PROVISIONAL SPECIFICATION
Improvements in Envelope Machines.
1, FRANCIS HENRY RICHARDS, a resident of Hartford (No. 64 Farmington Avenue,)
in the County of Hartford, and State of Connecticut, one of the United States of
America. Mechanical Engineer, do hereby declare the nature of my invention for
an IMPROVEMENT IN ENVELOPE MACHINES to be as follows:-
This invention is in the nature of an improvement on the envelope machine
described in the Specification of the British Letters Patent granted to me, No. 5517,
dated 21st April, A.D. 1886. The machine herein described automatically manu-
factures printed envelopes from blanks previously cut to the required shape, and
delivers the completed envelopes in bunches of twenty-five counted and banded ready
for boxing.
The framework of my improved envelope-making machine comprises a main frame
or bed, and its accessories and details, and several sinaller framework elements carried
thereon or thereby. And it may properly be said that each mechanism of the machine
has its own frame or bed especially adapted therefor, and which constitutes a part of
the general framework of the machine. Owing to the high speed of the machine,
(it making about 150 completed envelopes per minute,) and the desirability of
protecting from dust and thoroughly lubricating the principal cams, I have designed
a box-shaped main frame, wherein the principal parts of the actuating mechanism
are enclosed.
The main frame comprises the bottom plate, the front wall, rear
wall, right-hand end wall, left-hand end wall, and the top plate or table. In this
bed or frame are formed numerous openings and bearings, adapting it to receive the
doors, the removable bearings, and several operative details. The frame has in its
front wall a large opening that is covered by the front door; an opening in the rear
wall for the rear door; an opening in the right-hand wall for the right-hand
door and an opening in the left-hand wall for the left-hand door. The said
end walls have slots or recesses for the right-hand and left-hand main bearings,
respectively; also bearings for the first rock-shaft; and holes for certain
bearings of the stop mechanism. Other features of the main frame will be referred to
when describing the parts for which such features are provided. The several doors
or covers above specified are or may be secured in place by hinges and catches, in a
well-known manner now commonly adopted for similar purposes in other classes of
machines. The bottom plate is depressed in the middle part thereof to form a basin
or reservoir to collect the oil for lubrication, of which a considerable quantity
ordinarily lies on said plate. Extending around the outside of the base of the frame
1 usually form a base flange for supporting the machine; and surround this flange
with a rim or guard for catching any oil dripping from the bearings and other openings
in the walls of the main frame, or which may run down from the parts above the
hed for frame.
On the table or top-plate of said bed, the main column is set, and is securely
fixed in place by bolts through holes in flanges which extend along the sides and.
at the base of said column. This column is formed hollow, having the front wall,"
the rear face, and the right-hand and left-hand side walls; it also has a number
of holes, bearings, and seats for receiving or carrying various details of the
mechanisms. The front face of said column is recessed to form a guide for receiving
the frame (or bracket) carrying the mechanism or devices for operating the upper
creasing die. The rear side of said column is open except at the top. The right-
hand side wall and left-hand side wall are brought together at about the middle
of the column and formed into a recessed vertical bearing guiding the printing
slide. Holes in the top and bottom respectively of said column support bearings
for the picker cam shaft; other parts of the column.are described in connection
with the several mechanisms that are attached thereunto.
ל

page_text: CONCERNING THE ORGANIZATION.
The organization of this machine is such, and the inter-relation of the several
mechanisms is so intimate, that it is not practicable to attempt a strictly consecutive
description thereof, in the order in which the several operations are performed. For
in the description of one mechanism, it sometimes happens that reference is
necessarily made to other mechanisms not then described, so that the reader must
resort, in such cases, to the paragraphs in which such other mechanisms are described.
Furthermore, the division herein assumed of the machine into separate mechanisms,
is largely arbitrary and a matter of convenience, since many of the combinations set
forth are comprised in more than one mechanism as these are herein described.
These points being now understood, I will proceed to a detailed description of the
machine, beginning with those parts which for convenience I denominate
THE DRIVING MECHANISM.
The main cam shaft is supported in bushings which are secured in the main
cam shaft bearings that are fitted into the aforesaid recesses in the bed and secured
by screws and dowel pins in the usual manner. This construction allows these
bearings, together with the main cam shaft and all the cams thereon, to be moved
by drawing the bearings forward out of said openings, without separating or dis-
arranging those parts relative to each other. The driving pulley is fitted to rotate
freely on the main cam shaft, and the inside of the rim thereof is turned to fit
the friction cone. The hub of said cone is shaped to serve as a. pulley from which
to drive the inking mechanism. By this hub the friction cone is secured to the
main cam shaft by means of a key, and an adjusting nut; which nut is fitted on
said shaft for adjusting the friction cone, so as to properly engage with the conical
rim of the driving pulley when the machine is in operation. Said pulley is thrown
into engagement with said cone by means of dogs or levers, which are supported on
pivots that have their bearings in the arms of said pulley, and take their fulcrum
against the outer one of a pair of nuts on said shaft; they are operated by the
usual cam or cone which is free to revolve on the bushing and is moved by pins
in the ends of the arms of a shipper shaft that is supported in bearings on the bed
and is operated by means of shipper levers or handles. Said shipper shaft is also
operated in certain cases by the automatic stop mechanism.
The cams and eccentrics on the main can shaft are mainly similar to such parts
in ordinary use. The first rock shaft eccentric is secured to the main cam shaft by
means of a clamp screw through its slotted hub, or in any other ordinary manner,
and has an eccentric strap fitted to freely turn thereon. A stud is fixed in the pro-
jecting arm of a sleeve on the first rock shaft, and fits into a hole in the end of an
eccentric strap thereby imparting an oscillating motion to the first rock shaft, when.
the main cam shaft is rotated. The printing cam is secured to the main cam shaft
and operates the printing apparatus. The picker turret cam, consists of two faces, or
roller tracks, forming the opposite edges of a wide concaved rib, extending through
somewhat more than three hundred and sixty degrees; which rib for a part of its
length, preferably at each end is concentric with the main shaft and which for the
remaining part of its length is of a spiral form connecting said end portions. This
cam is secured to said main shaft by an ordinary key and a set screw, or in other
suitable and well-known manner. The turret and rolls on which the said cam
operates are considered to be parts of the picker mechanism and will be described in
connection therewith. The creaser eccentric operates the creasing apparatus. The
packing plate eccentric operates the packing plate double-cam. The seal-fold cam
and the seal-fold-carrier cam are formed together. Suitable cams are provided for
operating the inking roller, the placer slide, the back-fold lever, and the bunch-
plunger. The main shaft has a hand wheel which is securely clamped onto the left
and end thereof; and is provided with screw-collars for adjusting its position in its
bearings.

THE PICKER MECHANISM.
This mechanism is carried by the column, which is provided with a lower bearing
driven into a hole in, the lower end of said column, and an upper bearing for the
tubular shaft, which I designate the turret shaft. At its lower end, this shaft carries
the roll-turret which is provided with a series of arms or rolls engaging with and
driven by the main cam, for imparting an intermittent rotary motion to said shaft,
and to the picker turret which is carried on the upper end thereof. Said turret is
secured to said shaft, by a holding screw and by a clamp screw. The roll turret has a
series of hubs, four in number which are bored to receive the cam roll siems which
carry the rollers. Said stems are preferably held in place by clamping them in the
hubs by screws; the hubs being cut open on one side for that purpose.
The lower end of the roll turret is bored larger than the turret shaft, and is
threaded to receive a tubular adjusting screw. The point of this screw is tapered
so as to form a circular wedge for pushing out the stems, the inner ends of which
are preferably correspondingly bevelled or tapered, to secure a better bearing-
surface. A check-nut is usually provided to securely hold in place the said
screw. When it is required to spread out or enlarge the circle of the cam rolls
to a greater diameter for adjusting the bearing-pressure of said rolls on the
driving-cam, it is only necessary to loosen the said nut, and the clamp screws if
these are very tightly screwed up, and to then screw up the said wedge, as the
particular case may demand. To set in the rollers, the reverse operation is performed.
The wedge, being screwed down, the said stems are then driven in against it, and
again clamped as before. The tubular wedge may be threaded on the inside and fit
a corresponding thread on the turret shaft, if this modification shall be for any
reason preferable; and it should be understood that the other details are also capable
of modification in various ways and degrees, after the manner of machines in general,
within the scope and limits of my invention.
By the term "picker turret," when speaking of the mechanisms in general, 1 allude
to the entire upper portion of the picker mechanism. But in considering this
mechanism in detail, I designate the disc or frame as the picker turret, it being the
turret proper, which serves as a frame or base for carrying the operative details.
This turret, is secured to the said turret shaft by a holding set-screw, and carries the
picker frames into which are fitted to slide vertically, the hollow picker-spindles. The
turret has formed therein recesses into which are firmly fitted the picker frames; said
frames being made fast therein by holding screws. The spindles have feet formed
on their lower ends, to which are adjustably secured the picker-arms.
Said spindles have guide arms secured thereto by pins. The spindles are pushed
down by springs, the tension of these springs being adjusted from above, by the
adjusting screws which are threaded into the screw caps, and secured by check nuts;
the screws bear on follower plugs, and are lifted up by the lifting cam.
This cam
acts on the cam rolls affixed to the guide arms in any convenient way-as, for
instance, by means of studs fixed in the ears of said guide arms. The picker arms
each have on their inner end a stud, which pass through holes formed in the
feet of the spindles; nuts and washers serve to hold the picker arms in their proper
position.
The picker cam shaft has at its upper end a sleeve over which is loosely fitted a
guide sleeve, which together with caps secured thereto by screws, form guides, in
which the inner end of the guide arms are fitted to slide vertically. The said sleeve
and guides are held in place on said shaft by a nut and washer. The picker-arms may
be considered in pairs; the seal arms, and the back arms.

page_text: A series of picker-face studs are fitted to slide vertically, in the picker arms, the
lower ends of said studs being inserted in the picker faces; the said faces being
constructed of vulcanized rubber, the lower portion of which is of a softer constituency
than the rest the proper degree of hardness being ascertained by trial. The seal
picker plates, and the back picker plates, are, secured to said faces to stiffen the same.
The said studs are provided with springs, and with stop-pins to limit their movement
in the picker arms. The picker-cam shaft, and the picker cam (secured thereto hy a
key) have a rotary reciprocating movement imparted to them by means of the following
devices Fixed on the lower end of said shaft is a bevel gear, which is secured thereto
by a key, washer and nut; or other equivalent well-known means. Said gear meshes
with a segment which is fixed on the first rock, shaft. This shaft is actuated by an
eccentric, through a rod connecting it to an arm of the hub of said gear segment.
On the picker cam shaft between the picker cam and turret, I usually place a washer
to take up the wear.
:
On rotating the tubular turret shaft the rotating mechanism operates, to impart
an intermittent forward movement to the turret, carrying each spindle successively
to each station. At the same time the reciprocating mechanism operates to impart
a forward movement to the picker lifting cam during the same movement of the
turret and spindles, and a corresponding backward movement to said cam while the
turret is at rest. The forward movement of the spindles, and the same movement of
said cam are of similar velocity and extent, so that, while moving forward, the picker
cam rolls stand at about the same point on said cain, and thus practically impart no
vertical movement to said spindles; but on the return movement of said cam which
turns back about ninety degrees, each spindle is operated according to the conformation
of that portion or division of the cam passing under its roller.
During the several operations each spindle is brought successively to every station
and every spindle successively to each station; but whichever spindle may, during
one complete movement, be at a given station, its operation while there is always the
same at each different station the spindles have a different vertical movement.
THE GUMMING MECHANISM.
The framework or gum-box bracket, is secured to the column by screws. Said
bracket supports the gum plate bed, which is carried by its stem fitting into a hole in.
said bracket and is held from rotation therein by a guide pin. Within the sleeve of
said bed which is formed tubular for such purpose, the gum plate driver is contained;
which driver is connected to the gum plate through the medium of a projecting boss.
or hub, and the driver pin. Said hub fits into a recess in the upper surface of the.
flange of said shaft; which shaft is intermittently rotated by the gum plate driving.
gear, which is affixed to the lower end thereof, and is driven by a gear formed on the
hub of the fold turret driving gear, through two intermediate gears, and a pinion, that
is secured to the driver by means of a screw, a washer, and an ordinary key not shown.
The gum plate is raised to its proper working point by means of the gum plate
lifting shaft, which has on its inner end a crank pin; this stud engages with a block
which is fitted to slide in a slot formed in the sleeve of the gum-plate bed. A
handle is provided to turn the lifting shaft in its bearing; said shaft being held in
place longitudinally by a plug and detent spring, which are held in place by a
detent screw. Said block or shoe bears on a reduced and flatted part of the lifting
shaft, thus tending to hold the same in proper position.
The "gum-box," at its ends, rests on the gum plate bed; it is held in place
thereon at its inner end by an end-strap, which is secured to the gum-plate bed by
screws, and has a guide pin, fitting into a notch in said end of the gum box. At
its outer end, the gum box is fastened to said bed by a binding screw which is
operated by a handle, and whose thread is cut away on one side, the remaining
thread being less than one-half of a circle and fitting a half-nut formed in said
outer end of the box. A gum plate guard is secured to the gum box by a screw,
and is constructed to prevent the gum from flowing over the edge of the plate,

page_text: by guiding back thereon, any gum that may have already overflowed onto the edge
of said plate. Adjustable gumi gauges are provided for the purpose of regulating
the flow of gum through guarded narrow passages onto the guin plate, from the
space constituting the gum-box proper. Corresponding passages are on the opposite
sides of the box. since the unused gum is carried by the plate into the box again,
through these unguarded passages. Said gum gauges have tongues, which are
fitted to slide in inclined grooves formed in the gum box, and are held in place
by the washers and binding screws. The adjustment of these guages is effected by
means of adjusting screws which are journaled in bearings that are formed on
said box; each screw being furnished with a thumb nut for turning the same.
Posts or guides, are fixed in the gum box for the purpose of supporting the gum
bottle. Said bottle rests with its outlet in a space which communicates by a passage
with the gum receiving space; said passage leads in a curved way, and downward,
into said space, so that the foam formed in the latter space is prevented from
working up into the bottle. Within the first mentioned space there is a stop or
ledge, on which rests the mouth of the bottle neck.
THE END GUMMER.
33
In the manufacture of envelopes of the " high-pocket style, it is customary to
stick one end flap to the other, and to use for this purpose an auxiliary gumming
apparatus usually designated as an "end gummer." In my machines, this apparatus
is a substantially independent fixture. The end gummer standard, stands on the
cover of the feed-box, being secured thereto by screws and washers; said screws
passing through the foot of the standard. Said standard carries the end gum-box,
which is provided with a dovetail foot or base-plate, that is fitted under the corre
sponding part of the standard. A clamp which is removably secured to the standard
by a pin, and is adjusted by a clamp screw, serves to clamp said gum box in its
proper place on the top of the said standard.
The gummer gauge, is secured to the gum box by holding screws, and is adjusted
toward and from the gum roller by an adjusting screw. Posts are made fast in the
gum box, to support the bottle for holding the gum solution, and which rests on
a ledge formed in the interior of said box. A ratchet wheel, is provided with a
stud or shaft fitted to turn in its bearings which are formed on the gum box. The
gum roll is removably fixed on said stud by a key or like device, while a nut on
said shaft serves to hold together the several paris. The end gummer ratchet wheel
is actuated by a pawl; said pawl being pivoted on a screw fixed in a bracket, carried
on the end gummer slide. A spring serves to hold said pawl in engagement with
said ratchet wheel
A series of gummer pads are carried in a rotary holder which is carried on a hollow
sleeve that has thereon a ratchet wheel. Said ratchet wheel sleeve is fitted to turn
on a stud, that is fixed in the end gummer slide bracket. The said ratchet wheel is
actuated by a pawl, and is carried by a stud which is fixed in a bracket, that is
adjustably fixed to the standard, by a screw and washer. A spring, connected to the
standard by a screw, serves to hold said pawl in engagement with the said ratchet-
wheel. The slide bracket is secured to a slide by mans of screws, and these parts
together constitute one element of mechanisms, and may be made integral, if so
desired. Said slide is actuated by a connecting rod which takes hold of a stud
secured to the slide by a screw. This rod has a slot formed in the upper end thereof,
and a spring, serves to normally hold said stud against the bottom end of said slot.
The lower end of the connecting rod is connected by a stud to an arm, which is fixed
by its hub to the right-hand end of the first rock-shaft.
The mode of operation of this apparatus is as follows:-The gum bottle, having
been filled with the usual solution of gum, is placed in position between the posts;
and with the mouth thereof resting on the above mentioned ledge. The gum now flows
down filling the box up to the level of the bottle mouth. The gum roll has an inter-
mittent rotary movement imparted thereto, by the first rock shaft; through the

page_text: connections above described, including the slide bracket and pawl; which pawl
engages with the end gummer ratchet wheel. The gauge, or roll-scraper, is next
adjusted to regulate the amount of gum adhering to the gum roll, being adjusted by
the above described thumb screw. The gummer pads being located on the periphery
of a wheel, are successively brought into working position below the axis of said wheel
or holder, and afterward to the upper side thereof, said holder being turned forward
on each upward movement thereof.
Through the end gummer slide and connections, one of said pads is brought to
bear on the end flap of the uppermost blank of a pile of blanks, which pile, rests on
a feed plate of the blank-feed mechanism. The face or pad holder ratchet has as
many teeth or catches formed thereon, as there are gum pads; being six in this case.
The pawl which operates the said ratchet being fixed to the standard, is stationary ;
and operates. on each upward movement of the slide bracket, to turn the holder one
sixth of a revolution; so that on every upward movement of the said bracket, one
gummer pad face takes gum from the gum roll and on every downward movement
thereof another said face delivers gum to the topmost blank of the said pile of blanks;
the spring herein before mentioned, accommodates the operation of this apparatus to
the varying height of the said pile of blanks.
•
THE BLANK FEEDING MECHANISM.
The framework of this mechanism, which is conveniently made box-shaped, to
contain the intermediate shafts and gearing. Said framework rests on a ledge of
the column, and is secured to said column by screws. A top plate, which forms the
cover of said frame or box, and to the top of which the usual guides are fixed for
bolding the blanks in proper position laterally. These guides are four in number,
in two pairs, one pair at the front, and one at the back.
All of said guides may, and usually do have a slight adjustment on the top plite
to accommodate slight variations in the blanks, being held down in the usual manner
by screws and washers. The front guides are supported by brackets. The guides
rise directly from their bases, but have in this case, as they usually do in practice,
an outwardly projecting arm, for holding the separator device. This device consists
of an arm or lever, pivoted to one of the above said arms, and provided with a
separator-finger, which may be clamped therein by a screw. Springs are provided
to produce a slight downward pressure of the fingers onto the pile of blanks, being
connected to said arm and posts. Spring separator-fingers are secured to the
front-guides by washers and screws, and pass through slots formed in the inner side
of said front-guides.
A pile of envelope blanks is placed in proper position for the gummer, to take
up blanks therefrom; the pile, being placed on one of the blank-supporting plates,
for holding up said pile. A similar blank-supporting plate, is provided for receiving
a similar pile of blanks. These blank-supporting plates are respectively each upheld
by a similar set of vertically-movable plate-lifters. Each set of lifters consisting
of three rods. For communicating a simultaneous and equal vertical motion to all
the lifters in a set, two horizontal rods are provided and arranged to slide in bearings
formed in the frame. These rods are connected to acinate said lifters by and through
a system of gearing which is or may be substantially the same as that described
for a similar purpose in the aforesaid British Letters Patent No. 5517, dated
21st April A.D. 1886.
Said horizontal rods are similar in construction, and mode of operation to those
described for the same purpose in said Letters Patent, and are actuated from one of
the picker spindles through intermediate feed-mechanisin also substantially similar to
what is therein set forth.
The blank-supporting plates may have any shape to adapt them for being upheld
by the lifters and for holding the pile of blanks, said shape depending somewhat,
of course, on the shape of the blanks they are to hold. Suitable springs are fixed to
the underside of the plates, to engage with the lifter rods, and thus to hold the

page_text: plates with some little force in their proper position on the top of said lifters.
The operation of this blank-feeding mechanism is as follows: One of the blank-
supporting plates is placed in position on its own set of lifters which then stand
down. A pile of blanks is then placed on said plate and the plate with said pile on
it is lifted up until the top of said pile is at the proper height. The envelope-machine
being now started up, the blanks are taken one by one from the pile, the plate
being fed up in the meantime by means the mechanism above referred to.
While this is going on the operator places the other plate in position on the other
set of lifters, and places thereon a pile of blanks. The rod for elevating said
other plate is now drawn forward, lifting the second plate until its pile of blanks
reaches the first plate, when said first plate is pulled out, letting the remainder
of the first pile rest on the second pile. The first rod is then turned to disengage
its feed-pawls and is slid back, thus lowering the first lifters when the first plate
is again placed on them and a third pile of blanks on that, to be fed up as
before. In this way the machine may be run continuously, the blanks being fed at
convenient intervals.
THE BLANK-OREASING MECHANISM.
The frame or upright, for carrying the creaser slide, is fitted to the front wall
of the column in a usual manner, being-secured thereto by holding screws.
Said
upright has formed thereon guides to which is fitted the creaser slide; which
slide has a vertical movement imparted to it by the creaser eccentric that is carried
on the main cam shaft, through the several arms and connecting rods hereinafter
described. The said slide has an adjusting bracket, which is adjusted by a screw; a
holding screw and washer serve to hold said bracket in place.
The angle-lever or rocker arm, is pivoted in the creaser upright, by a pin. Tho
creaser arm link connects the adjusting bracket and said arm; being furnished with
pivot pins for that purpose. The creaser connecting rod is pivoted to said rocker
arm by a pin, and to the inside creaser arm, by a similar pin. The creaser arm is
clamped onto the creaser arm shaft by a clamp screw, and may also be keyed thereto,
since, in practice, this fastening should be securely made. Said shaft also carries
the outside, creaser arm, whereby this shaft is actuated; said arm being clamped
thereto by a clamp screw, and connected to the creaser eccentric by a pin.. The said
eccentric rod passes through a hole or slot, formed in the top plate of the main bed,
and has at its lower end a creaser eccentric strap which is fitted to the creaser
eccentric on the main cam shaft. The creaser die base or bed, rests at its inner end.
on the column, and at its outer end on the creaser frame; it being held in place
thereon by screws which pass through the holes in said bed.
The creaser slide, has formed in the lower end thereof a dovetail groove to receive
a dovetail formed on the creaser-blade-holder; said holder having the creaser blades
secured thereto by the screws. The inside lower edges of the said creaser blades are
bevelled, and the outside of the same concaved; these blades are preferably constructed
of steel and should be well tempered; said blade holder, together with said blades,
constitutes the upper creasing die." The lower creasing die consists of the sido
blocks, the end blocks, the die bed, and the minor details supporting said blocks on
said bed. The blocks are fitted to turn on the hinge pins of the hinge plates; said
hinges being adjustably secured to the creaser bed, by the holding screws. The side
blocks have secured thereto the lower side spring plates, and the upper, side spring
plates, by screws. The end blocks have similarly secured thereto the lower end spring
plates and the upper end spring plates; the said side and end blocks are yieldingly
upheld by springs, their upward movement being limited by stop surfaces.
The lower spring plates rest on the side and end blocks, and are secured thereto
in the manner above described; they consist of a flat portion, an angular portion, and
a curved edge. The upper spring plates are similarly formed. The said plates are
in practice, made of spring steel; the edges, and angular portions thereof, are split.
or sawed forming numerous fingers; the cuts of the upper plate alternating with the
cuts of the lower plate so that one finger of an upper plate shall rest on two of the

page_text: The operation of the above-described printing mechanism is as follows. An envelope
blank having been carried by the pickers to the proper position between the upper
and lower creasing dies, the upper die is now brought down forcibly onto said blank,
thereby holding the blank firmly in place by means of the creasing blades as before
set forth; and while said die remains on the paper, the type, being previously inked,
is brought up against, and prints the blank. The operation of the slide is so timed
by the proper shaping of the printing cam, that the printing is completed, and the
type withdrawn from contact with the blank, while this is firmly held between the
creasing dies. This feature, in practice, enables the printing to be performed very
rapidly, without any displacement of the blank on the pickers.
THE INKING MECHANISM.
The ink fountain has its seat on the column, being secured thereto by screws, the
lower edge of said fountain resting on a ledge of said column. The ink fountain roll
is carried on the ink fountain roll shaft; said shaft being journalled in the end walls of
the ink fountain. Said shaft has affixed to its outer end a ratchet-wheel through which
it is rotated by means of a pawl.
The ink fountain gauge plate or roll-scraper, is secured to the inclined front wall of
said fountain, by holding screws, and is provided with adjusting screws; the office of
said gauge plate being to regulate the quantity of ink carried on said roll. The ink
fountain pawl is operated by the ink fountain pawl eccentric, on the ink fountain cam
shaft said shaft also carries the transfer cams and a
worm gear.
The ink
transfer roll, is carried on the transfer roll shaft, said shaft being journalled
in slide bearings; these slides are provided with movable caps; springs
serve to hold said caps in their proper place, and yet allow the transfer
roll to recede under a certain pressure. The springs which bear on spring pins
fixed in the slides, serve to hold said slides always in contact with the transfer cams;
When the said slides are allowed
said cams imparting a vertical movement thereto.
by the revolving of said cams to assume their lowest position being forced down by
the said springs the transfer roll is brought in contact with the ink fountain roll from
which the said transfer roll receives a coating of ink. When in the course of
their revolution the transfer cams have raised the slides to their uppermost point, the
transfer roll is brought in contact with the ink distributing cylinder, to which
it delivers the ink it has received from the ink fountain roll.
Stop pin bosses formed on the ink fountain form bearings for the stop pins ;
these pins being provided with stop pin springs. Holes in the slides are provided
to receive the stop pins when the operator wishes to lock the slides, to prevent
the transfer roll taking ink from the ink fountain roll. The stop pin is provided
with a knob which has inserted therein a pin. When by means of the knob the
stop pin has been fully drawn out, and turned to one side, so that said pin shall
not re-enter one of said holes, in the said bosses, but shall rest on the face of said boss,
the stop pin is thus prevented from entering said hole in said slide; said slide is
then free to be operated as aforesaid. The ink distributer roll is carried on the
distributer roll shaft said shaft being journalled in vertically movable shaft bearings;
said bearings being provided with springs.
The oscillating ink-distributer-roll cam is carried on a supporting screw stud
which passes through the hub of said cam; an arm is formed on said hub, said
arm being forked at the end thereof to receive the cam actuating pin, which is
fixed in the ink fountain pawl. A grooved cam roll is made fast to the outer end
of the distributer roll shaft. The inclined or spirally-formed working edge or
face, of said cam is fitted to work in the said groove of said cam roll. The said
face of said cam being at an angle to the axis of the ink distributer roll shaft,
as the cam is oscillated by the ink fountain pawl through a pin, it gives a forward
and backward movement to the distributer roll, thereby distributing the ink evenly
over the surface of the ink distributing cylinder. This operation is strictly
analogous to the distribution of ink in ordinary printing presses, and hence need
B

page_text: not herein be further set forth. The ink-distributing cylinder is carried on the
distributing cylinder shaft; said shaft. being carried in proper bearings. Said shaft
also carries a spiral gear. The ink fountain vertical shaft passes through a hole
formed in the top plate of the bed, and has an upper bearing and a lower bearing.
Said shaft has secured thereto at its upper end a spiral gear which meshes with
the above-mentioned spiral gear; and said shaft also carries a worm that 'meshes*
with a worm gear on the ink fountain cam shaft. The said vertical shaft has
secured thereto at its lower enda mitre gear meshing with a mitre gear carried
on the ink fountain pulley shaft; said shaft being carried in a bushing, which in
turn has its bearing in the main bed. Tlie ink fountain pulley shaft is rotated
by the ink fountain pulley, which receives its power from the main cam shaft,
through a belt. The inking roll, on the inking roll shaft, is carried by a forked
inking roll carrier. Said carrier is held in the inking roll carrier clamp, by means
of a clamp screw; said clamp being pivoted at the upper end of the inking arm
by a pin a carrier spring is provided to give a downward pressure to the said
carrier. The inking arm is pivoted in the inking arm bearing by the inking arm
stud, and passes through a hole formed in the top plate of the main bed, and has:
at its lower end the inking arm cam roll, which is secured to said arm by a stud.:
Said cam roll bears on the inking roll cam on the main cam shaft, whereby said
roll is actuated in proper time. The inking arm bearing is secured to the top
plate of the main bed. The inking arm is provided with a pull spring the opposite
end of which is carried by a hook screwed into the column.
THE FOLDING MECHANISM.
"
This portion of the machine comprises the "folding turret," and folding apparatus
operating in connection therewith to fold the back-flap and the seal-flap. The
bearing sleeve, carrying the folding turret is affixed by its flange to a part of the
side-wall of the column by screws; its tenon being fitted into a hole in said
column. The turret-shaft is carried in said sleeve and at its enlarged outer end
is connected by a pin to the tubular shaft that carries the "spider" or frame of
the folding turret proper. The folding turret is actuated from the tubular .turret
shaft by closely-fitted gearing.
The driven bevel gear is keyed fast to the inner end of said fold turret shaft,
being held thereon by a nut; it meshes with the corresponding driving gear which
is fitted to slide on the tubular turret shaft and on the key or spline thereof, being
held in place in proper mesh with gear by an adjusting nut which may be a clamp-nut
or collar, held together by clamp-screws. By this means, as the teeth of said
gears wear away, the said gear may be mored upward to bring the said teeth
into a firm bearing again for in practice these gears should run without any play
or back-lash. Said pair of gears are skew bevels," the axis of the fold turret
shaft being about one-half of an inch rearward in the machine of the axis of the
tubular turret shaft; this arrangement is adopted to permit a better arrangement
of the fold plates, on the turret spider; said plates being set forward, in their
line of movement, for the purpose of co-acting with the back-flap folder, as
hereinafter more fully set forth.
The fold turret spider consists of the hub and four arms, each arm carrying one of
a series of folding-plates. Each folding plate has hinged thereto at each end, end-
fold wings right and left; which wings have adjustable shoes, right and left for
gauging the "thickness" of the edge of the folded envelope, being adjusted by set
screws and binding screws in a well-known manner. The hubs of said wings are
bored to receive studs, carrying cam rolls which run in the grooves of the oscillating
end-fold cams, whereby said end wings are actuated. Said cam roll studs are held in
place by binding screws which clamp said hubs (which are split on one side thereof,)
firmly to the stem of said studs. Thickness collars separate the end-fold cams from the
spider; the outer cam being held in its proper place on a sleeve by a washer and nut.
The end-fold cams have a rotary-reciprocating movement imparted thereto by

page_text: connecting rods which are secured to said cams by means of screws. Said connecting
rods are connected at their lower ends to studs which are fixed in arms on the second
rock shaft, by nuts. This rocker is actuated from the first rock shaft by an arm, a
connecting rod, and an arm on said second rocker; the arms having pins respectively,
for said rod. The back folding wing is carried by an arm or lever which is carried
on a shaft for that purpose, said arm passes through a hole formed in the top plate of
the bed, and has at its lower end a cam-roll, which bears on the back-fold cam, on
main cam shaft; which cam operates to draw forward said folder, the work of folding
the back flap being performed by a spring. Said shaft is an eccentric one, carried at
its inner end in a bearing on the column, and at its outer end in a clamp bearing
affixed to the bed by screws; by loosening said screws, said shaft may be turned to
throw the back-fold plate either toward or from the fold turret. Said plate is adjustably
attached to the upper end of the back folding arm by a stud which passes through said
upper end and is held therein by a nut.
The seal-folder consists of an arm, which has secured across its forked ends, a folder
bar. Said arm is adjustably secured to a carrier arm, which has formed thereon an
arm, to one side of which arm is fastened one end of a spring, whose opposite end is
made fast to the top plate of the bed. The carrier arm is forked at its upper end,
and is provided with a shaft, on which shaft, and between the said forks of the arm
is loosely fitted the seal fold carrier. The said arm is carried on the soal folder
eccentric stud, said stud being journalled in a bearing, that is formed in the left-hand
wall of the main bed. The lower part of the seal fold carrier arm passes through a
hole formed in the top plate of the bed, and carries at its end a cam roll, which bears
on the seal fold carrier cam. The seal folding arm, is also carried on the seal fold
eccentric stud and is formed at its upper end to bear on an arm of the carrier.
A spring is provided to always hold the said carrier arm in contact with the said
cam. The seal fold arm carries at its lower end a cam roll, bearing on the seal
folding cam, on the main cam shaft. The horizontal movement of the seal folder is
derived from the seal fold carrier cam through the carrier arm; and the vertical
movement thereof from the seal fold cam, through the seal fold arm; and these two
movements are so timed by the corresponding shaping of said cams, as to produce the
required movement as set forth of the seal-fold bar.
The operative parts of this mechanism are actuated from the second rock shaft.
The lower transfer arm has a hub, which is fitted onto said rock shaft, and is secured
thereto by a pin. The lower transfer arm has, secured to its outer end by a screw
stud, the transfer arm connecting rod; said rod being connected to the upper transfer
arm, by means of a stud. The said upper arm is adjustably secured to the transfer
shaft, by the transfer arm binding screw, the hub of said arm being split on one side
for that purpose; the transfer shaft has its bearing in the gum-box bracket, the sleeve
and boss forming a part of said bearing.
The upper nipper is pivoted to a hollow sleeve by the upper nipper stud, which
passes through the ears on said sleeve; the said nipper has secured thereto one end
of a spring, the other end of said spring being carried by an arm, on the said hollow
sleeve, the function of said spring being to hold up the outer end of the upper nipper;
said nipper also has formed thereon a stop-arm, to limit the upward movement thereof.
The lower nipper has at its outer end a hollow stud, (sometimes provided with a rubber
covering,) and also has formed integral therewith a sleeve, bored to loosely fit on the
transfer finger shaft, also a hub, bored to fit the rock shaft, to which it is secured by
a pin. The transfer finger is secured to a fixed shaft or stud, by means of a pin ;
the transfer finger is also secured to said shaft by a pin. The transfer finger connecting
arm which is formed integral with the said finger is pivoted on a stud, said stud being
fixed in an arm on the transfer shaft by the nut. The said arm is connected to the
outer end of the transfer shaft as to.a stud, by means of a screw and washer ; said

page_text: shaft has a rocking movement imparted to it by the second rock shaft through the
connections herein before described.
The transfer adjustable arm is adjustably clamped to the transfer shaft by a clamp
screw the hub of said arm being split to permit of this. The arm formed on the sleeve
is adjustably secured to the transfer adjusting arm by means of screws and washers,
said screws passing through slots in said arm and being screwed firmly into said
adjusting arm. The hollow sleeve is bored to receive the rock shaft which is fitted
to turn freely in said sleeve; the rock shaft arm is secured to the inner end of said
shaft, by a pin in the usual manner; said arm having a stud secured to its outer end
by a nut, said stud carrying one end of the transfer finger connecting rod. The
transfer friction clamp, is in two parts, binged together on a stud, said stud being
provided with a nut.
The friction clamp is provided with friction leathers, which bear on the outer
surface of a sleeve formed on the gum box bracket; a clamp screw, a spring, and a
check nut, are provided for regulating the pressure of said friction. The clamp
furnished with the leathers as set forth, is fitted to a reduced part of the said sleeve.
The rocking movement of the rock shaft is imparted thereto by the transfer shaft,
through the said clamp, a connecting rod, and rock shaft arm, pinned to said rock
shaft. A stop secured to the arm on the hollow sleeve by holding screws, and provided
with a stop screw, and a stop screw check nut, serve to limit the rocking movement
of the said rock shaft in its bearing.
When the transfer adjusting arm is carried up the said connections revolve the rock
shaft in its said bearing to throw up the upper nipper; at the same time throwing
down the lower nipper, and drawing back the transfer fingers. At this time the
folding plate has brought an envelope in position above the transfer trough ready to
be taken hold of by said nippers, and deposited in said trough. Next, the reverse
movement of said shaft operates to close said nippers onto the envelope, and firmly
grip the same. Continuing its motion, the said arm carries the closed nippers down
while the preceding envelope is pushed along by the transfer fingers to a position
between the fingers of the endless carrier.
The transfer trough is supported on a base that is securely fastened in place on top
of the framework of the machine, by means of ordinary screws. Said trough is made
fast to said base by screws, and is provided with caps, which are secured to the edges
of said trough by screws. The said caps have formed thereon ears, to receive the
pivot pin carrying the detent pawls. Pawl springs are provided to lightly hold down
said pawls; said springs being secured to the caps by holding screws. Said pawls are
arranged in pairs; designated the first pair, second pair.
When in the operation of the machine as aforesaid, the nippers have grasped the
envelope by the seal flap, (said envelope being still carried on the folding plate, and
held in place thereon by the end-fold wings); as the end-fold wings release said
envelope the nippers transfer it to a position below the detent pawls; the envelope
being still in the grasp. of the nippers. The nippers now release the envelope, and
return ready to grasp another envelope. The first pair of pawls serve to prevent the
return of the envelope, should it happen to adhere to the nippers in any way. The
nippers now take another envelope and, as before carry it to the transfer trough,
the transfer fingers at the same time push the first envelope beyond the second pair of
pawls, (whose office is the same as that of the first pair,) and into the endless carrier,
allowing it to rest on one of the carrier fingers. Grooves are formed in the trough
to provide for the free passage of the transfer fingers, as these project below the
envelope.
THE ENDLESS CARRIER.
This element of the machine consists in an endless belt or apron, provided with
fingers for holding the envelopes. Said fingers are formed or fixed on a finger base
which is provided with the envelope-stops, that overlap the bases of the adjacent
fingers. The driving bar having teeth, and the driver pins formed thereon, is secured
to the said base by screws this clamps the endless belt firmly between said parts,
the

page_text: A few details of this mechanism are carried by a bracket which is fitted on and
secured to a shelf that is formed on the rear side of the top plate of the main bed.
But the greater portion of said mechanism is carried by the packing box beil-plate,
which is secured on the main bed, adjoining the aforesaid part. The envelope plunger
slide is carried by said bracket, being fitted to move between suitable ways or guides
thereon; these ways comprise the upper guide, and the lower guide, said guides being
fixed to the bracket by screws.
The envelope plunger is pivoted to a slide by a screw stud; said plunger has two
stops, the upper stop which is formed on the said slide, and the lower stop which is
secured to the said slide by a screw. The plunger for the purpose of cushioning the
same, is provided with a leather strap or buffer, which is secured by screws on the
projecting end or stop-arm of said plunger.
The slide is usually provided with a friction device consisting of a cap, a piece of
leather, a screw, and a spring. By turning the screw, the tension of the spring may
be adjusted, for regulating the pressure of the clamp and leather on the lower guide,
and thus control the resistance of the friction device to the slide movement. The
purpose of that resistance is to furnish a means for operating the envelope plunger
on its pivot. The envelope plunger arm is carried on the envelope plunger shaft;

page_text: which turns in a bearing in the rear wall of the main bed, and has a second bearing,
formed on the left-hand wall of said bed.
The envelope plunger shaft is actuated forwardly by a spring which is connected
by a pin to an arm, that is secured by a pin to said shaft. The opposite end of said
envelope plunger spring is connected to a pin fixed in the rear wall of the bed. The:
envelope plunger is operated. backwardly by a cam on the first rock-shaft; which
cam acts through a roll which is carried on a stud, fixed in an arm, that is fixed by
its hub and clamp-screw to the plunger arm shaft, adjacent to its bearing. The face
: of said cam is shaped to impart to said plunger the proper movement. The said
cam is secured to the first rock shaft by its hub and a clamp screw. The envelope
plunger arm is adjustably secured to the outer end of the plunger arm shaft by
means of a clamp screw and is pivotally connected at its upper end to the said
envelope plunger by means of a stud fixed in said arm by a nut, and works in a slot
formed in said plunger.
"
دو
The nature of the said construction is such, that when the parts assembled sub-
stantially as described, that a reciprocating movement of the plunger arm imparts a
four-motion movement to the forward end of the envelope plunger. This is for
the purpose of permitting the said plunger to go forward while the chain or carrier
stands still, and to return while said chain is going forward. This movement being
completed, the plunger then goes back to its original position, ready for the next
operation.
THE ENVELOPE PLACER.
The first rock shaft also carries the envelope placer arm whose hub is bored to
fit loosely on said rock shaft. The curved face of said arm bears on the placer slide
roll which is carried on a stud fixed in said placer slide. The envelope placer cam is
carried on the main cam shaft, and actuates said arm through the placer cam roll,
which is carried by a stud, fixed in the said arm by a nut. The placer slide is provided
with a spring which with the placer arm operates the said slide; the inner end of
said spring being supported by a hook which is made fast in the main bel; the.
outer end being carried by a tension hook said hook being carried by an arm of said
placer slide, and being provided with an adjusting thumb nut; the said spring
passing through an opening. formed in the rear wall of the bed.
The placer slide is fitted to slide on a guide or rib on the packing box bed plate
which rib fits in a groove formed in said slide. At its inner or forward end said
slide rests on a shelf of the bed; and at its outer or rearward end is supported by
two caps or gibs, which are held by screws to the under side of said bed plate.
This bed plate (secured to the main bed by screws) has a shelf or ledge, on which
the envelope-way is set, being held thereon by screws. The purpose of said way is
to furnish a guide. or track onto which the envelope may be delivered by the chain
and accessory devices, and on which the envelope may be slid along into the
packing box.
Accordingly, the track on which the lower edge of the envelope rests, coincides in
height and alignment with the lower surface of the packing box. The envelope placer
is carried by the placer slide, being secured thereto by a holding screw. The counting
arm is carried on the counting arm stud, and is provided with one or more counting
.fingers which are fitted to normally pass through slots, formed in the placer. Said
counting arm is actuated in one direction by the counting cam which acts on a roll
that is carried on a stud; it is reversely actuated first by an envelope carried against
said counting fingers, and then by the releaser cam which is affixed by a screw to the
arm of the placer slide, and which strikes the releaser cam on said arm.
The mode of operation of said devices is as follows. On the backward movement
of said placer and placer-slide, the counting cam acting on a roll, throws, the counting
arm into a position with the fingers standing back of the way or track, and with the
shaft releaser, cam standing clearly below the long releaser cam. The envelope being
now brought by the chain nearly up to the way, the placer on its forward movement
carries it, against the counting fingers, and thus throws the counting arm into a

page_text: 4:
position where the short releaser cam stands above the line of the long releaser cam;
and on further forward movement of the placer. said cams engage, and (owing to the
steep inclination of their working faces.) instantly throws the counting fingers
forward of the said way, thus releasing the envelope from its clamped position between
said placer and counting fingers. This operation se:s "the counting devices ready
to turn the "stop wheel," but does not actually turn that wheel; this is done on the
outward sta oke of the counting cam; which acts in a positive manner on the counting
arm which is connected to actuate said wheel. By this means each complete move-
ment of the machine causes the stop-wheel to be turned; provided an envelope' is.

plate and is carried by a stud, that is removably fixed in a notch formed in said
bed plate Said wheel has a ratchet-wheel whereby it is turned. "The connections
for actuating the wheel from the counting arm, consist of a pawl arm-carried on the
hub of the said wheel; said arm being pivoted at its lower end, to a connecting rod
by a screw stud. A counting pawl is carried on the counting pawl by a pin; and
operates the ratchet. The said arm is actuated by the said connecting rod pivoted

:
MODE OF OPERATION.
The completed envelopes having been delivered to the endless carrier or chain,
said carrier being operated by the endless carrier driving mechanism as hereinbefore
described, said envelopes are carried upward over an ordinary supporting pulley, and
down on the opposite side, between the right-hand and left-hand guides, and forward
of the outer: or. rear guide. The envelope placer which is operated as before
t

page_text: described, pushes the said envelope one by one slightly forward to its proper position
on the envelope way; the upper edge of said envelope resting against the said
projection of the packing box front plate; from this point the said envelope, after
being counted as herein before set forth, is pushed by the envelope plunger into the
packing box, and rests with its edge on the supporting plate of said box.
The operation of the packing plates and of the course of an envelope entering said
box, may be described as follows. Suppose a number of envelopes to be in the
packing box, the first packing plate being fully closed, and holding said envelopes in
place; the second packing plate being fully open, and the envelope plunger pushing
an envelope into said box; the first packing plate now opens to admit of the full
entrance of said envelope. Both packing plates now fully open, and the envelope
plunger pushes the envelope into the packing box and against the end plate; said plate
thus acting as a stop for the envelope. Both the first and second packing plates now
fully close, carrying the last entered envelope to place; and the plunger returns to its
position, preparatory to bringing forward another envelope. The first and second
packing plates are operated by the packing plate cams hereinbefore described, said
cams being constructed and timed suitably therefor. The above operations are
repeated until twenty-five envelopes have been packed in the said packing box, when
the bunch plunger pushes the said bunch of envelopes out of the packing box and into
the bunch trough a band being placed thereon as the bunch passes from the packing
box to said trough; the said banding operation being accomplished in a manner
hereinafter described.
The operation of the bunch plunger is as follows. A pull spring operates to
turn the bunch plunger. arm shaft in its bearing, through a cam roll arm, the
turning of said shaft giving a forward movement to the said plunger, through the
bunch plunger arm. Each time an envelope is taken by the piacer, and is placed
upon the envelope way in the manner above described, the counting ratchet plate
(which is fixed to or formed on the counting ratchet,) is turned on its stud (by
means of said ratchet, and the connections hereinbefore described,) through the
one twenty-fifth part of a complete revolution. The form and timing of the bunch
plunger cam is such as to allow the bunch plunger to be thrown forward, (by
the means above described) on the completion of each movement of the said plate.
The bunch plunger stop hook coming in contact with the said plate, prevents the
further forward movement of said plunger, which is immediately returned to its
position by the said cam (the forward movement of the plunger, in this case,
being very slight, usually about the one thirty-second part of an inch): on the
completion of the twenty-fifth movement, or one complete revolution of said
ratchet plate, at which time twenty-five envelopes have been placed in the packing
box by the envelope plunger, a notch, formed in the said plate has been brought
into line with the stop hook, the plunger is thrown forward by the means above
described, pushing twenty-five envelopes out of the packing box and into the
bunch trough; the bunch plunger being immediately returned to its original
position by means of the bunch plunger cam.
THE BANDING MECHANISM.
:
For convenience of description, this mechanism may be considered in two divisions,
consisting of the hand-placing apparatus, and the band-making apparatus. The latter
takes a previously prepared tube of band material, feeds the same to the shears

slide is provided with a spring; said spring being connected at one end by a pin which
is fixed in the said slide, the opposite end being connected to a pin that is fixed in the
slide cap. Said slide cap is secured to the band carrier arm by holding screws, which
0

page_text: arm is provided with stop screws; and with a holding screw and washer; said holding
screw serving to adjustably secure said carrier arm to the band carrier arm, whose hub
is bored to turn freely on the fixed band carrier shaft or stud, it being held in place on
said shaft, by collars; said collars being fixed on the said shaft by set screws.
Ears formed on the hub of the band carrier arm, are provided with a chain pin,
carrying a chain; said chain having at its lower end a pin, which carries one end of
the band-carrier-spring whose opposite end is held by a spring hook that is fixed in the
main bed near the base thereof.
The band pusher is provided with a holding screw and washer, by which it is
adjustably secured to the band pusher arm, whose hub is fitted freely on the band
carrier shaft. Said pusher is moved in one direction by a spring that is connected at
one end to a pin in the hub of the band carrier arm, and at the other end to a pin in
the hub of the band pusher arm. A leather washer is usually provided to cushion the
blow of the said hub as the same is thrown forward.
The band pusher arm has formed thereon a lug, which stands forward of the point
of the outside let-off arm. The said arm is fixed by its hub and pin to the let-off shaft.
The inside let-off arm has a hub fixed on the let-off-arm shaft by a set screw; said
shaft having its bearing in the bed of the banding mechanism. Said inside lot off arm
engages with the stop arm which is formed on the banding-cam-shaft sleeve.
The band knock-off connecting rod is pivoted to the outside let-off-arm by a screw
stud or pin; and said rod is connected by a stud or pin to the lower knock-off arm,
said stud being held in place by a nut. The said arm passes through an opening
which is formed for that purpose in the rear wall of the bed, and is fixed by a pin or
otherwise to the lower end of the band knock-off shaft or stud. Said shaft has its
bearing in the bed-plate of the packing mechanism, but passes freely through a hole
formed in the shelf of the main bed. The band knock-off cam lever is fixed or formed
on the upper end of said shaft, and has adjustably secured thereto (by screws and
washers) the band knock-off cam; which cam is adjusted on said arm by an adjusting
screw usually having a check nut. The knock-off cam is actuated by a roll on the
bunch-plunger lever as hereinbefore referred to.
The band carrier shaft or stud is supported in a hole formed in the bed or frame of
the banding mechanism bed being fixed therein by a set screw. Said bed rests on a
ledge or shelf, and against a wall at the rear side of the bed. The hub of the band
carrier arm has formed thereon a connecting rod arm provided with a stud (held in
place by a nut,) for the band carrier connecting rod; which rod passes through an
opening formed in the rear wall, of the bed, and is connected by a stud (held in place
by a nut,) to the band carrier rock arm, whose hub is fitted to turn freely on the band-
carrier rock-shaft, this shaft being carried in the bearings that are supported within
the main bed by screws. Said hub has formed thereon another arm, provided with a
stud (held in place by a nut,) carrying a cam roll, that bears on the bending cam.
The banding cam-shaft is carried in a right-hand bearing and a left-hand bearing
which bearings are secured to the main bed by screws; the right-hand bearing has a
set screw for holding in place therein the said shaft. The banding cam is formed on
the banding-cam sleeve on which are also formed various other cams and parts, herein-
after mentioned. The banding cam gear is carried on the said sleeve between two
leather friction washers; which are clamped between the fixed. friction-plate, and the
movable friction-plate that is forced against said washer by the friction spring plate
and the friction adjusting nut.
The banding pinion shaft bearing is secured to the right-hand wall, of the main bed
or frame, by holding screws; the hub of said bearing passing through a hole formed
in the said wall. The pinion shaft has on its inner end the banding pinion, fixed
thereto by a pin. The said shaft carries at its outer end a hand wheel having a
handle.
The banding-mechanism driving-pulley, is fitted to turn freely on the pinion shaft
and its hub is bored to receive a pawl, and a spring for actuating said pawl; said
pawl engaging with the ratchet teeth, formed on the hub of said hand wheel. The
aid pulley is driven by an ordinary band or belt from a pulley-face on a sleeve which

page_text: extends inwardly from the ink fountain pulley that is fixed on its shaft. Said shaft is
driven by a band from a pulley formed on the friction cones as hereinbefore stated in
connection with the inking mechanism.
The arrangement of driving mechanism here described, permits the handing
mechanism to be operated forwardly by hand, the pawl yielding whenever the hand-
wheel is turned faster than said pulley.
THE BAND-MAKING APPARATUS.
The band-tube feed-roll bracket is secured, as before stated, to the band mechanism
bed by holding screws. The band-tube upper feed-roll shaft is provided with a knob
pinned to said shaft; said shaft is carried by bearings which are fitted to slide vertically
in rectangular slots, formed in the said bracket, and are provided with bearing springs,
bearing spring washers, and bearing spring tension-screws; which screws are carried
in bearing caps that are fixed on the said bracket by cap screws.
The upper feed-roll shaft carries a sleeve fixed thereon by a pin ; which sleeve has
formed or assembled thereon the upper band feed rolls, the shuttle guide flanges, and
a gear. The band-tube lower feeds-roll shaft has it bearings in the banding
mechanism bed, and in the feed-roll bracket, and passes freely through an opening in
the rear wall of the main bed. Said shaft carries freely thereon a sleeve which has
formed thereon the band-tube lower feed-rolls, a gear meshing with and driving the
before-mentioned gear; also a ratchet-wheel whereby said sleeve and feed-rolls are
driven.
The hand-tube feed-pawl, which engages with the said ratchet wheel, is carried
on a pawl stud that is fixed by a nut in the feed-pawl arm. A spring is secured
to the said arm and bears on à flattened part of the said pawl, to hold said pawl
in engagement with the said ratchet. Said pawl arm is secured to the lower feed
roll shaft by a pin, and is actuated backward by the pawl-arm-spring, that is
connected at one end to a hook on said arm, and at the other end to a hook
on the feed-roll bracket. The movement of the pawl-arm is regulated by a stop
that is adjustably fixed on the said bracket by a screw.
The said lower shaft has
secured at its inner end the hand-feed arm, which has a stud, (fixed therein by a
nut,) that carries a cam roll which roll bears on the hand-feed cam, that is
formed on the banding-cam-shaft sleeve. The rotation of said cam imparts a
forward movement to band feed arm and through the lower shaft and through the
pawl-arm, pawl and ratchet, to the feed-rolls; the return movement being made by a
spring, as aforesaid.
OPERATION OF THE BANDING MECHANISM.
A rocking movement is imparted to the band carrier by the banding cam through
the arms and connections hereinbefore described. When the bunch plunger arm
is allowed, as before described, to throw forward the bunch planger, it also operates
through a cam roll, the knock-off cam, and the knock-off lever, to turn the knock-off
arm shaft in its bearing; and the turning of said shaft operates, through an arm, the
knock-off connecting rod, the outside let-off arm, and the let-off arm shaft, to
disengage the inside let-off arm from the stop-arm, which is formed on the banding
cam sleeve. As soon as this disengagement takes place the said sleeve, and the
cams thereon are revolved, on its shaft by the frictional driving apparatus hereinl efore
described, through one full revolution, and until said let-off arm again strikes said stop
armi and thus arrests said movement. During said revolution, said cams on said sleeve
severally perform the work for which they are designated. Said sleeve is allowed to
make but one revolution each time it is started; since the inside arm is immediately
returned to place, in the path of said stop arm.
The banding cam, formed or the banding cam sleeve, operates through a cam roll,
and the connections before described, to turn the band carrier arm, on the band carrier
shaft down to one side; at the lower part of said movement, the band carrier slide

page_text: strikes a stop and thus closes the long band carrier finger against or nearly to, the
short band carrier finger. The band tube is now fed forward in a manner hereinafter
described, the band carrier fingers receiving the end of the said tube; the band shears
are next operated by the shear cam, through the connections described, to cut off a
band, which is deposited on the said band-carrier fingers. As the band carrier arm
now returns to its first or upright position, the slide spring operates to separate the said
band carrier fingers, which thus expand the said band thereon.
.
The operation of placing a band on a bunch of envelopes, may be described as
follows. The desired number of envelopes having been placed in the packing box by
the envelope plunger, the bunch plunger pushes said envelopes out of said box in the
manner hereinbefore described. At the same time that the bunch plunger moves
forward the outside let-off arm engages with a lug formed on the hub of the band-
pusher-arm; this causes the said hub to slide on the band carrier shaft, carrying with
it the band pusher, which pushes the band off from the band carrier fingers, and places
it on the bunch of envelopes as they leave the packing box, said bunch being deposited
in the bunch trough, forward of the bunch pusher.
The operation of feeding the band tube onto the band carrier fingers, is as follows.
The tube is slipped by hand over the tube opener of the band shuttle, and between the
band shuttle rolls, and the upper and lower feed rolls; paper guides are provided to
prevent the band tube from passing between the two front shuttle rolls, as it might
sometimes do in the absence of said guides. The tube material is held firmly between
said rolls by reason of the springs hereinbefore described. The band tube is now
ready to be automatically fed forward; this being accomplished by the band feed
cam, and its connections herein before described.
The rocking of the lower feed-roll shaft, operates through the feed pawl arm, and
the feed pawl, which engages with the feed ratchet, to intermittently revolve the band-
feed rolls. The four small band shuttle rolls being fitted to freely turn on pivot screws,
and the feed-rolls being firmly pressed against the tube material by said springs, the
turning of said feed rolls acts to draw forward the band tube over the shuttle, leaving
this always in the same position. The pressure of the said feed rolls on the band
tube is regulated by thumb screws. The normal longitudinal position of the shuttle
between the feed rolls, is maintained by reason of the entering of said feed rolls between
the small shuttle rolls.
The upper band-shear blade is screwed to the upper band-shear-arm, by the upper
blade screws; the upper shear arm is carried on the upper shear-arm-bushing, which
is secured to the feed-roll bracket by a screw stud. The lower band shear blade is
screwed to the lower band shear arm; the said arm is carried on the lower shear
arm bushing which is screwed to the feed roll bracket by a screw stud. The upper
shear arm has formed thereon the upper shear segment, whose teeth mesh with those
of a segment which is formed on the lower shear arm. A shear guard provided
with band-tube guide-arms is secured to the said bracket by holding screws.
The shears are operated by a connecting rod which is connected to an arm that is
formed on the lower shear, and has a stud fixed therein by a nut; said rod passes
through an opening formed in the rear wall, of the main bed and at its inner end,
is connected by a stud and nut, to the shear cam-roll-arm. Said arm carries, ou a
stud held therein by a nut, a cam-roll, which bears on the shear cam, that is formed
on the banding-cam sleeve. The said arm is fixed by its hub and a pin to the band-
carrier rock-shaft; which shaft is thus turned forwardly by said arm. The opposite
movement of said shaft and arm, is effected by a pull-spring which is connected by
a chain to the bunch-pusher arm that is also fixed on said shaft, and hereinafter again
refered to.
THE BAND TUBE SHUTTLE.
This part consists of the shuttle-frame, four hand-shuttle rolls which are screwed
into the said frame; one upper shuttle-spring secured to the frame by two holding
screws; one lower shuttle-spring also secured to the frame by two holding
Cl
مسم

page_text: one end of which is carried on the said stud, and the opposite end by a hook fixed
in the said lower bearing is provided to impart a downward pressure to the said latch.
The stop rod has a right-hand and a left-hand bearing, fixed in the end walls of the
main bed. The said stop rod is provided with a stop rod collar, pinned to said rod,
and a stop-rod spring; said rod has near its left-hand end a notch formed therein, to
receive the point of the said latch.
The operation of this stop-motion apparatus is as follows: The envelope plunger
receives its backward and forward motion from the plunger arm shaft as hereinbefore
described; the office of said plunger being to push the completed envelopes one by
one, out of the endless carrier, and into the packing box. The machine is set in operation
by throwing the main driving pulley into engagement with the friction cone, by means
of either of the shipper-handles this at the same time, through the shipper handle
arm pushes back the stop rod until the latch drops into the notch formed in the
said rod.
The machine being now in operation, and having pushed an envelope into the said
packing box, the plunger immediately starts on its backward movement; the stop-
motion connecting rod simultaneously moving forward (being carried by the stop-
motion arm) the pawl arm strikes one of the contact pins, causing the friction disc
to turn on the stop-motion shaft, until the notch of said disc is brought into line with
the notch formed in the edge of the shaft disc. The plunger is now fully back; and
immediately starts on its next forward movement, the said connecting rod at the same
time moving in the opposite direction; the pawl arm strikes the other contact pin,
thus returning the disc to place.
This return is thus accomplished provided that the plunger moves fully forward;
but should the movement of said plunger be obstructed in any manner, as, for instance,
by disarranged envelopes, then the plunger does not move fully forward; the said
arm is not thrown back far enough to strike the contact pin; the said disc remains
in its position, and the notches are still in line. As the plunger now moves backward,
the said rod moves forward causing the pawl to slide on the edge of the discs; the
notches being in line, the point of said pawl drops into said notches.
The said pawl cannot engage with the notches until these are brought into line; at
any other time said pawl may pass over said notches, the edge of one disc acting as a
bridge, to carry the pawl over the notch in the other disc. When the said notches
are in line, the connecting rod on continuing its forward movement turns the discs
by means of the said pawl; as the guard disc is fixed to the stop-motion shaft by a
pin, said shaft is turned in connection therewith, causing the latch arm to lift the latch
out of said notch; and thus release the said stop rod, then thrown forward by the
stop rod spring; this movement of said stop rod operates through the shipper handle
arm, to turn the shipper shaft, and said shaft through the shipper shaft arms, disengage
the driving pulley, from the friction cone, in a manner hereinbefore described, thereby
stopping the machine.
THE AUTOMATIC BUNCH PLUNGER STOP MOTION.
This mechanism is similar in construction and operation, to the envelope-plunger
stop-motion above described. A stud is fixed in the bunch plunger arm and carries
one end of a connecting rod, whose opposite end is connected to the connecting rod
stud that is fixed by a nut in the pawl arm. This arm is carried on the hub of the
friction disc; the stop-motion pawl is carried on said stud, and is beld by the pawl-
spring against the edges of the stop-motion discs. The bunch-plunger stop-motion
shaft has its upper bearing in a bracket which is secured to the top plate of the main
bed by screws; the lower bearing of said shaft is formed on the flange of the left-
hand bearing of the first rock-shaft. At the lower end of the said shaft, is
secured a mitre gear which meshes with a similar gear that is fixed on the stop-
motion shaft.
The bunch-plunger stop-motion disc is pinned to the bunch-plunger shaft, and has
formed in the edge thereof a notch similar to the notches above described; the friction

page_text: disc is provided with a hub, bored to fit the said shaft and has formed in the edge
thereof a similar notch; said disc is also provided with a similar pair of contact pins.
Friction clamps, provided with leather friction washers, which bear on the hub of
the friction disc. The clamps are provided with a clamp screw, a nut, and a
spring said clamps are also provided with a stud, fixed in the bunch stop-
motion bracket. The operation of this mechanism will be understood without further
explanation, it being the same as that of the envelope stop motion hereinbefore
described. Any obstruction preventing the full forward movement of the plunger,
causes the notches formed in the discs to be brought into line, so that on the return
stroke the pawl catches in said notches and thus turns the bunch stop-motion
shaft to release the stop rod and thus allow the stop rod spring to stop the
machine, as heretofore more fully pointed in connection with the envelope-plunger
stop-motion.
GENERAL OPERATION.
The general operation of my improved envelope-machine is as follows: A pile of
blanks, which have been previously cut to the required shape and size, are placed
upon the blank-supporting plate between the guides; and the blank-feeding devices
are then set to properly feed up said plate to bring the uppermost blank to the
separators. The gum box is next supplied with suitable solution of gum, and the gum
spreading appliances suitably adjusted to properly spread the gum on the gum-plate;
and this plate is elevated by means of a handle and the devices hereinbefore described
to bring its upper surface to the proper plane for the descending rearward picker to
strike thereon. The ink fountain is also supplied with ink; the machine being run
idle for a few moments, to properly distribute the ink over the several rollers of the
inking apparatus.
The machine now being started, by means of one of the shipper handles and con-
nections described for that purpose, the picket turret carrying the picker arms is
intermittently revolved in the manner, and by the means set forth in the description
of the picker mechanism." On the first downward movement of the pickers, (said.
movement being governed by the picker cam,) one pair of pickers is lowered onto
the gum plate receiving a coating of gum therefrom; these pickers are now raised by
the said cam, and the turret is turned forward one quarter of a revolution, thereby
carrying the pickers that have just taken gum to a position immediately above the
said pile of blanks. One end Hap of the topmost blank, of the said pile of blanks,
having been gummed by the end gumming mechanism as hereinbefore set forth, the
return movement of the said cam now allows the pickers to be again lowered, the
gummed pair onto the pile of blanks, and the second pair onto the gum plate.
This done, the said pickers are immediately lifted by said cam, the first-mentioned
pair carrying with it a blank, from the said pile, which the gum has caused to adhere
thereto; the picker turret is again turned forward one quarter of a revolution,
carrying the biank on the first pair of pickers to a position immediately between the
upper and lower creasing dies. The picker turret cam again allowing the pickers
to be lowered, the blank carried by the first pair is lowered onto the upper side spring
plates, and the upper end spring plates of the lower creasing die. At the same time,
the second pair of pickers is lowered onto the gun plate.
The upper creaser die is now brought down in the manner, and by the means
herein before described, and the afore-mentioned blank is creased, without removing
it from the pickers by which it is carried. While the first-mentioned blank
is firmly held between the upper and lower creasing dies, the type, (having been pre-
viously inked by the inking roller in the manner hereinbefore fully described, and by
means of the inking cam and its connections,) is brought up against the said blank by
means of the printing cam, (and the arms and connecting mechanism hereinbefore
described therefor,) thus printing the said blank, and being immediately withdrawn
therefrom. As soon as the blank has been printed, the upper creasing die is raised,
and releases the blank.

page_text: The can now raises again the pickers, and the turret is turned forward one
quarter of a revolution, carrying the first blank to the folding station, the second blank
to the creasing station, the third pair of pickers to the blank station, and the fourth-
pair of pickers to the gumming station. The picker turret cam now allowing the
pickers to again be lowered, the first blank rests on one of the folding plates; the
second blank on the lower creasing die; the third pair of pickers on the pile of blanks,
and the fourth pair of pickers on the gum plate. The end-fold wings are now
operated by means of the end-fold cams, to fold down the end flaps of the first blank;
the outer wing operating a little in advance of the inner wing, so that the outermost
flap, (which has been previously gumnied as before stated,) shall overlap the inner-
most flap. While this operation is being perforined, the second blank is being creased
and printed in the manner before described. The pickers being again raised as before,
and the end-fold wings holding the first blank firmly to the folding plate the upward
movement of the pickers detaches the blank from said pickers. The said turret is
now revolved one quarter of a turn in the same direction, by means of the gearing
hereinbefore described. This brings the back-flap of the envelope against the upper
edge of the back-flap folder, and thus partially folds over the said flap. The back-fold
cam now operates, through an arm, and its connections, to press the back-fold wing
firmly against the back flap of the first blank, sticking the gummed edge of said
flap firmly to the end flaps. While the last-mentioned operation is being performed,
the end flaps of the second blank are being folded, and a third blank is being creased
and printed, all in the manner above described. The fold turret is again turned one
quarter of a revolution in the same direction; and the seal-folder is operated by the
Seal-fold cam, and the connections described, to turn or fold over the seal flap of the
first blank on its creased line, without pressing the gummed edge thereof to the back
flap of the said blank; this being prevented by the edges of the end-fold wings, which
are shaped therefor in a well-known manner. During the performance of the last-
mentioned operation, the back flap of the second blank is being folded over and closed.
down; the end flaps of the third blank are being folded; and a fourth blank is being
creased and printed. The fold turret spider now makes another quarter turn in the same
direction; this movement having been completed, the seal flap of the first blank,
(which has now been completely folded, and should therefore be designated as an
envelope,) is grasped by the upper and lower nippers of the transfer mechanism; at
the same time, the end-fold cams operate to raise the end-fold wings, and release the
said envelope from the folding plate of the fold-turret. The said transfer mechanism
now operates as hereinbefore described to transfer the envelope that has just been
folded, from the fold-turret to the transfer trough. The nippers having transferred
one envelope from the folding turret to the transfer trough return immediately for
a second envelope; and as this is delivered to the said trough, the transfer fingers
push the first envelope into the endless carrier or apron, said envelope resting on one
of the fingers of said carrier. As herein before described, said endless carrier is carried
on a supporting pulley suspended overhead in a well-known manner, and is operated by
the endless carrier driving apparatus, to carry the envelopes up and over said pulley
and down on the opposite side thereof; this circuit taking a sufficient time to allow
the gum on said envelope to thoroughly dry. As the envelopes are brought one
by one by the carrier to the counting apparatus, they are placed by the placer, onto
the envelope way, and are there counted as hereinbefore particularly described.
The envelope-plunger operates to push the envelopes one by one along said envelope
way into the packing box; and as hereinbefore stated in the detailed description of
the said packing box, when twenty-five envelopes have been placed in said box, the
bunch plunger is operated to push the said envelopes, out of said packing box, and
into the bunch trough; the band being placed on the said bunch as it passes through
the band-carrier, on which carrier the band has previously been placed, as explained
in detailed description of the banding mechanism. Thus the bunches of completed
envelopes are banded and delivered to the bunch trough forward of the bunch pusher,
which operates as hereinbefore described to push the said bunches along the said

page_text: trough between, and past the bunch hooks to the front of the machine, where they are
taken by the operator and packed into boxes for shipment.

The framework of my improved envelope-making machine comprises a main frame
or bed, and its accessories and details, and several smaller framework elements carried
thereon or thereby. And it may properly be said that each mechanism of the machine
has its own frame or bed especially adapted therefor, and which constitutes a part of
the general framework of the machine.. Owing to the high speed of the machine, (it
making about 150 completed envelopes per minute,) and the desirability of protecting
from dust and thoroughly lubricating the principal cams, I have designed a box-
shaped main frame, wherein the principal parts of the actuating mechanism are
enclosed. The main frame is designated in a general way by A, and as shown herein
(see Figs. 5-8) it comprises the bottom plate 2, the front wall 3, rear wall 4, right-
hand end wall 5, left-hand end wall 6, and the top plate or table, 7. In this bed or
frame are formed numerous openings and bearings, adapting it to receive the doors,
the removable bearings, and several operative details. The front wall 3 has the
larger opening 8, covered by the front door 8"; opening 9, in wall 4, for the rear
door 9 opening 10 in wall 5, for the right-hand door 10; and opening 12 in wall 6,
for the left-hand door 12". The end walls 5 and 6 have the slots or recesses 13
and 14 for the right-hand and left-hand main bearings, respectively; also bearings 15
and 16 for the first rock-shaft 119; and holes 17 and 18 for certain bearings of the
stop mechanism. The other features of the main frame will be referred to when
describing the paris for which such features are provided. The several doors or
covers above specified are or may be secured in place by hinges and catches, in the
well-known manner now commonly adopted for similar purposes in other classes of
machines. The bottom plate, 2, is depressed in the middle part thereof to form a
basin or reservoir to collect the oil for lubrication, of which a considerable quantity
ordinarily lies on said plate. Extending around the base of the frame A, I usually
form a base flange, 2ª, for supporting the machine, and surround this flange with a
rim or guard, 2b, for catching any oil dripping from the bearings and other openings
in the walls of the main frame, or which may run down from the parts above the
bed A.
On the table or top-plate 7, of bed A, the column B is set, and is securely fixed
in place by bolts through the holes 4 (Figs. 9 and 11) in the flanges 51 and 52
which extend along the sides and at the base of said column. The column B is
formed hollow, having the front wall 49, rear face 50, and right-hand and left-hand

page_text: side walls 53 and 54; it also has a number of holes, bearings, and seats for receiving
or carrying various details of the mechanisms. The front face 49, of column B. is
recessed to form a guide for receiving the frame (or bracket) carrying the mechanism
or devices for operating the upper creasing-die. The rear side of column B,
designated by 50, is open except at the top. The right-hand side wall 53 and left-
hand side wall 54 are brought together about the middle of the column and formed
into a recessed vertical bearing, 59, guiding the printing-slide. The holes 55 and 56
in the top and bottom respectively of column B support bearings for the picker-cam
shaft. 62 and 63 designate the recesses for the inking-cams. The other parts of
column B are described in connection with the several mechanisms that are attached
thereto.
CONCERNING THE ORGANIZATION.
The organization of this machine is such, and the inter-relation of the several
mechanisms is so intimate, that it is not practicable to attempt a strictly con-
secutive description thereof, in the order in which the several operations are
performed. For in the description of one mechanism, it sometimes happens that
reference is necessarily made to other mechanisms not then described, so that the
reader must resort, in such cases, to the paragraphs in which such other
mechanisms are described. Furthermore, the division herein assumed of the machine
into separate mechanisms, is largely arbitrary and a matter of convenience, since
many of the combinations set forth and claimed are comprised in more than one
mechanism as these are herein described. These points being now understood, I
will proceed to a detailed description of the machine, beginning with those parts
which for convenience I denominate
The main cam shaft, designated by numeral 70, is shown best in Fig. 13. It is
supported in bushings 45 and 46, which bushings are secured in the main cam-shaft
bearings 47 and 48. These bearings are fitted into the recesses 13 and 14 in the bed A,
and secured by screws and dowel pins in the usual manner. This construction allows
these bearings, together with the main cam-shaft and all the cams thereon, to be
removed by drawing the bearings forward out of openings 13 14, without separating.
or disarranging these parts relative to each other. The driving-pulley 72, Figs. 13
and 64, is fitted to rotate freely on the main cam shaft 70. The inside of the rim of
driving-pulley 72, designated by numeral 73, is turned to fit the friction-cone 74.
The hub, 75, of cone 74, is shaped to serve as a pulley from which to drive the inking
mechanism. By this hub the friction-cone 74 is secured to the main cam-shaft 70, by
means of the key 77 and the adjusting nut 76; which nut is fitted on said shaft; for
adjusting the friction-cone 74, so as to properly engage with the conical rim 73 of
driving-pulley 72 when the machine is in operation. Said pulley 72 is thrown into
engagement with said cone 74 by means of the dogs 80 and 81. which are supported
on pivots 82 and 83 that have their bearings in the arms of said pulley 72, and take
their fulcrum against the outer nut 84, (of the pair of nuts 84 and 85.) on shaft 70;
they are operated by the usual cam or cone 86, which is free to revolve on the
bushing 45, and is moved by pins in the ends of arms 88 and 89 (Figs. 64 and 65);
which arms are attached to and form a part of the shipper shaft 87, that is supported
in bearings 90 and 91 on bed A, and is operated by means of the shipper levers or
handles 92 and 93. The arm 94 on shipper handle 93 is operated by the automatic
stop-mechanism. Springs 78, acting against the collar 79, are usually provided to
force apart the pulley 72 and said rim or cone 74, in a well-known manner.
cams and eccentrics on main cam-shaft. 70 are shown in Figs. 13, 14, 19 and 67. The
first rock-shaft eccentric 101, is secured to the main cam-shaft 70 by means of a
clamp screw throngh its slotted hub, not shown, or in any other ordinary manner,
The

page_text: "
;
and on this eccentric the strap 131 is fitted to freely turn. A stud 132 is fixed in the
projecting arm 134 (of the sleeve 133) on the first rock-shaft, and fits into a hole
in the end of eccentric-strap 131, thereby imparting an oscillating motion to the first
rock-shaft, when the main cam-shaft 70 is rotated. The printing cam 102 is secured
to the main cam-shaft 70, and operates the printing apparatus.. The picker-turret
cam, C, is part of a mechanism for converting motion shown in U.S. Patent
No. 297,165, granted to me April 22, 1884, and as described in said prior patent
consists of two faces, or roller tracks 136 and 137, forming the opposite edges of a
wide concaved rib, extending through somewhat more than three hundred and sixty
degrees which rib for a part of its length, preferably at each end is concentric with
the main shaft 70 and which for the remaining part of its length is of a spiral form
connecting said end portions, substantially as shown. This cam is secured to shaft 70
by an ordinary key, not shown, and set-screw 103, or in any other suitable and well-
known manner.
The turret and rolls on which the cam C operates are considered to
be parts of the picker mechanism and will be described in connection therewith. The
creaser eccentric 104 operates the creasing apparatus. The packing-plate eccentric 105
operates the packing-plate double cam. The seal-fold cam is designated by 106, and
the seal-fold-carrier cam by 107; these two cams are shown formed together.
Cam 108 is for operating the inking roller. Cam 109 operates the placer-slide ;
110, the back-fold lever and 111, the bunch-plunger. The direction of the rotation
of the respective cams is shown by the arrows in Fig. 14, their relative positions on
shaft 70 being indicated by their position relative to the lines ab ab. The numeral 112
designates the hand-wheel which is securely clamped on to the left-hand end of the
cam-shaft 70, in the usual manner; 113 designates a nut, and 114 a jam nut on said
shaft. The first rock-shaft, designated by the numeral 119, is best shown in Fig. 13.
Said shaft is supported in the bearings 120 and 122; these bearings are fitted in the
holes 15 and 16 respectively, formed in the walls 5 and 6, of the main bed A. The
numeral 121 designates a flange formed on the bearing 120, a similar flange 123
being formed on the hearing 122. The rocker arm sleeve 133 is secured to shaft 119
by a pin, in the usual manner; the arm 134 is usually formed, as shown, integral with
said sleeve, as also the segment 135 which operates the picker cam shaft 241.
Shaft 119 also carries the second rock-shaft driving arm 140, the envelope-placer
arm 143, and the envelope-plunger cam 148.
THE PICKER MECHANISM.
This mechanism is carried by the column B, which is provided with a lower
bearing 185 (which is fitted at 185" (Fig. 20) to be driven into the hole 56 in the
lower end of column B,) and the upper bearing 184, for the tubular shaft 186, which
I designate the turret-shaft. This shaft passes through the hole 19, in the top plate 7,
of the bed A, and at its lower end carries the roll-turret D, provided with a series of
arms or rolls engaging with and driven by cam C, for imparting an intermittent
rotary motion to said shaft, and to the picker-turret 210 carried on the upper end
thereof. Said turret D is secured to shaft 186, by holding screw 187 and a clamp
screw at 188. (See Figs. 19 and 20.) Turret D has a series of hubs, four in number
as shown, which are designated as 189, 189, 189, and 189, respectively, and are
bored to receive the cam roll stems 190, 190, 190, and 190°, which carry the
rollers 191, 191, 191, and 191. Said stems are preferably held in place by clamping
them in the hubs by screws 192, 192ª, 192, and 192°; the hubs being cut open on one
side, as shown, for that purpose. The lower end of turret D is bored larger than the
shaft 186, and is threaded to receive the tubular adjusting-screw 193. The point of
this screw is tapered as at 194, Fig. 20, to form a circular wedge for pushing out the
stems, the inner ends of which are preferably correspondingly beveled or tapered, as
at 195, to secure a better bearing-surface. A check-nut, 196, is usually provided to
securely hold in place the screw 193. When it is required to spread out or enlarge
the circle of the cam-rolls to a greater diameter for adjusting the bearing-pressure of
said rolls on the driving-cam C, it is only necessary to loosen nut 196, (and perhaps

page_text: screws 192, if these are very tightly screwed up,) and to then screw up the wedge 193
as the particular case may demand. To set in the rollers, the reverse operation is
performed. Wedge 193 being screwed down, the said stems are then driven in against
it, and again clamped as before. The tubular wedge 193 may be threaded on the
inside and fit a corresponding thread on shaft 186, if this modification shall be for
any reason preferable to that shown in the drawings; and it should be understood
that the other details are also capable of modification in various ways and degrees,
after the manner of machines in general, within the scope and limits of my
invention.
The
By the term "picker-turret," when speaking of the mechanisms in general, I
allude to the entire upper portion of the picker mechanism, which is shown in
Figs. 24 and 25. But in considering this mechanism in detail, I designate the
. disk or frame 210 as the picker-turret, it being the turret proper, which serves as
a frame or base for carrying the operative details. This turret, 210, is secured to
shaft 186, by a holding set-screw, 211, and carries the picker frames 212, into
which are fitted to slide vertically the hollow stems or picker-spindles 213.
turret 210 has formed therein the recesses 232, into which are firmly fitted the
picker-frames 212, said frames being made fast therein by the holding-screws 233.
(See Fig. 26.) The spindles 213 have formed on their lower end the plates or
feet 214, to which are adjustably secured the picker-arms, 219 and 219. (See
Fig. 32.) Said spindles 213 have the guide-arms 215 secured thereto by pins 216.
Said spindles 213 are pushed down by springs, 209, the tension of these springs
being adjusted from above, by the adjusting-screws 208, threaded into the screw-
caps 207, and secured by check-nuts 206; the screws 208 bear on the follower
plugs 205, and are lifted up by the lifting-cam 240. This cam acts on the cam-
rolls, 217, affixed to the guide-arms 215, in any convenient way, as for instance,
by means of studs, 218, fixed in the ears, 215", of said guide-arms. The picker-
arms, 219, each have on its inner end a stud, 220. (see Fig. 23,) which studs
pass through holes 221, formed in the feet, 214, of the spindles 213; and the
nuts 222 and washers 223 serve to hold the picker-arms in their proper position.
The shaft 241 has at its upper end a sleeve, 242, over which is loosely fitted the
guide-sleeve 243, which together with the caps 244, secured thereto by screws 245,
form guides, in which the inner end of the guide-aruns are fitted to slide vertically.
See Figs. 24 and 27. The said sleeve and guides are held in place on shaft 241
by nut 246 and washer 247. The picker-arms 219 may be considered in pairs:
the seal arms, designated by 219, and the back arms, designated by 219. A
series of picker-face studs, 226, are fitted to slide vertically in the picker-
arms 219; the lower ends of said studs 226 are inserted in the picker-faces, 227
and 227, as shown in Figs. 21 and 22; the said faces being constructed of
vulcanized rubber; the lower portion, shown by the finer shading and designated
by 234, (see Figs. 21 22,) is of a softer constituency than the rest, the proper
degree of hardness being ascertained by trial. The seal picker plates, 228, and
the back picker plates, 228, are secured to said faces 227 and 227", to stiffen
the same. The studs 226 are provided with the springs 229, and with stop-
pins, 230, to limit their movement in the picker-arms. The picker-cam shaft, 241,
and cam 240, (secured thereto by key 248,) have a rotary reciprocating movement
imparted to them by means of the following devices. Fixed on the lower end of
said shaft is the bevel gear 250, which is secured thereto by key 251, washer 252,
and nut 253; or other equivalent well-known means. Said gear meshes with a
segment, 13, which is fixed on rock-shaft 119. This shaft, 119, is actuated, as
shown in Figs. 13 and 67, by the eccentric 101 through rod 131 connecting to
arm 134 of the hub 133 of said gear segment 135. On shaft 241, hetween
cam 240 and turret 210, I usually place a washer, 249, to take up the wear.
In Fig. 133, the picker-cam 240 is shown in perspective, the better to exhibit the
several portions thereof. In Fig. 134 I have shown the rim of said cam as if broken
in two and straightened out, and have supposed the picker-spindles 213 to be situated
in a straight line alongside thereof; and as the spindles have the same movement

page_text: as the rollers 217, I have for the sake of simplicity omitted in this figure the
drawing of said spindles, and have shown the rollers designated by their proper
numerals said rollers being considered as symbols of themselves and of the spindles
together. In this Figure 134, I have mapped out the several successive movements
of the pickers as these pass around the circuit of the mechanisms, showing five
successive positions of the system of pickers, as designated in the column at the left-
hand of said fig. The operation is as follows: On rotating shaft 186, the rotating
mechanism operates, as above described, to impart an intermittent forward motion to
the turret, carrying each spindle 214 successively to each station (1, 0³, 0³, C+, C¹,
respectively. At the same time the reciprocating mechanism operates to impart a
forward movement to the cam 240 during the same movement of the turret
and spindles, and a corresponding backward movement to said cam 240 while the
turret is at rest. The forward movement of the spindles, and the same movement of
cam 240, are of similar velocity and extent, so that, while moving forward, rolls 217
stand at about the same points as 240, 240, 240, 240, on said cam, and thus
practically impart no vertical movement to said spindles; but on the return movement
of cam 240, which turns back about ninety degrees, each spindle is operated accord-
ing to the conformation of that portion or division of the cam passing under its roller.
In position 1st is shown the positions of the spindles 213 and the several parts of
cam 240 relative to each other and to the stations indicated by C1, C2, C3, C4, at the
completion of a forward movement of the whole, this being toward the left-hand. In
position 2nd the cam is represented as in the middle of its return movement toward the
right-hand, the several spindles standing at different elevations, corresponding to the
various shapes of the respective portions 241ª, 241, 241°, 241", of said cam. In
position 3rd the return movement of the cam has been completed, the relation of
spindles and cam being the same as in position 1st, except that all the spindles are
advanced one station in respect to the cam, but themselves continuo to stand at the
same stations. In position 4th the cam and spindles are shown advanced through
one-half of their forward movement, having all gone forward together without any
change in respect to each other. In position 5th this forward movement is com-
pleted, the spindles being each advanced to next succoeding station from the place
thereof in the 1st position. The several operations continuing as described, cach
spindle is brought successively to every station and every spindle successively to each
station; but whichever spindle may, during one complete movement, be at a given
station, its operation while there is always the same; at each different station the
spindles have a different vertical movement.
THE GUMMING MECHANISM.
In the general views, Figs. 1, 2 and 3, this mechanism is designated in a general
way by the letter G. The framework or gum-box bracket, 391, is secured to the
column B, by screws 392, as shown in Fig. 36. See also Figs. 66 and 67. Bracket 391
supports the gum-plate bed 396, which is carried by its stem 398 fitting in the
hole 396, Fig. 66, and is held from rotation therein by guide-pin 397. Within the
sleeve 398, which is formed tubular for such purpose, the gum-plate driver 399 is
contained, which driver is connected to the gum-plate 406, through the medium of the
projecting boss or hub 405 and the driver-pin 400. Said hub fits into a recess 404, in
the upper surface of the flange of said shaft 399, which shaft is intermittently rotated
by the gum-plate driving gear 410, which is affixed to the lower end thereof (Fig. 38)
and is driven by the gear 407, on the hub of gear 816. through the intermediate
gears 408 and 409, and the pinion 410, that is secured to the driver 399 by means of
a screw 411, a washer 412, and an ordinary key not shown. The gum-plate 406 is
raised to its proper working point by means of the gum-plate lifting shaft 431, which
has on its inner end the crank-pin 432; this stud engages with the block 433, which
is fitted to slide in a slot in the sleeve 398, as shown in Figs. 35, 36 and 40.
handle, 434, is provided to turn shaft 431 in its bearing; said shaft being held in
place longitudinally. by the plug 435 and detent-spring 436, which are held in place by
A
E

page_text: the detent-screw 437. Said shoe 435 bears on the reduced and flatted part 430 of the
shaft 431, thus tending to hold the same in proper position. The "gum-box," 441, at
its ends rests on the gum-plate bed 396; it is held in place thercon at its inner end
by the end-strap 401, which strap is secured to bed 396 by screws 402, and has a
guide-pin, 403, fitting into the notch 442, in said end of the gum-box. At its outer
end, the gum-box is fastened to said bed by a binding-screw, 443, which is operated
by handle 444, .and whose thread is cut away on one side as at 443ª, the remaining
thread being less than one-half of a circle and fitting the half-nut 480, (Fig. 4.1.)
formed in said outer end of the box. A gum-plate guard, 445, is secured to the
gum-box by a screw, 446, and is constructed to prevent the gum from flowing
over the edge of the plate, by guiding back thereon any gum that may have already
overflowed onto the edge of said plate. The adjustable gum-gauges or scrapers, 447
and 448, are provided for the purpose of regulating the flow of gum through the
guarded narrow passages 426 and 427, (see Figs. 36, 40, 41 and 42,) onto the
gum plate from the space 440 constituting the gum-box proper. Corresponding
passages 428 and 429, are on the opposite sides of the box 441, since the unused gum is
carried by the plate into the box again, through these unguarded passages. Said
gum-gauges have tongues, 449 and 450, respectively, which are fitted to slide in the
inclined grooves 451 and 452, formed in the gum-box, and are held in place by
the washers and binding-screws 453. The adjustment of these gauges is effected by
means of adjusting-screws 454 and 455, which are journalled in bearings 456 and 457
that are formed on said box 441, each screw being furnished with a thumb nut for
turning the same. Posts or guides, 481, are fixed in the gum-box 441, for the
purpose of supporting the gum-bottle 482, as illustrated in Figs. 36, 37 and 39.
Said bottle rests with its outlet in the receptacle or space 483, which communicates
by passage 484 with the space 440. Said passage 484 leads in a curved way, and
downward, into space 440, so that the foam formed in the latter space is prevented
from working up into the bottle. Within space 483 there is a stop or ledge, 485,
(Figs. 39 41,) on which rests the mouth, 4824, of the bottle neck.
THE END GUMMER.
In the manufacture of envelopes of the "high-pocket" style, it is customary to
stick one end-flap to the other, and to use for this purpose an auxiliary gumming
apparatus usually designated as an "End Gummer." In my machines, this appa-
ratus is a substantially independent fixture, designated in the general views by EI,
and shown more in detail on a larger scale in Figs. 43 to 46, inclusive. The
standard 486 stands on the cover F2, of the feed-box F, as shown in Figs. 28 and 29,
being secured thereto by screws and washers 488; said screws passing through the
foot, 487, of the standard. Said standard 486 carries the gun-box 489, which is
provided with a dovetail foot or base-plate 490, that is fitted under the correspond-
ing part, 491, of the standard. The clamp 494, which is removably secured to the
standard 486 by the pin 495, and is adjusted by the clamp-screw 496, serves to clamp
said gum-box in its proper place on the top of the said standard.
The gummer
gauge, 500, is secured to the gum-box 489 by holding-screws 501, and is adjusted
toward and from the roller 515 by the adjusting screw 502. The posts 507, made
fast in the gum-box 489, serve to support the bottle 508, for holding the gum
solution, and which rests on a ledge 509, formed in the interior of said box. The
ratchet-wheel 513 is provided with a stud or shaft 514, said stud being fitted to
turn in its bearings 512 512, formed on the gum-box 489. The gum-roll, 515, is
removably fixed on said stud 514, by a key or like device not shown, while the
nut 516 on said ratchet-shaft serves to hold together the several parts. The ratchet-
wheel 513 is actuated by the pawl 517, said pawl being pivoted on a screw, 518,
fixed in the bracket 545 carried on the slide 546. A spring 519, (Fig. 43,) serves
to hold said pawl in engagement with said ratchet-wheel. The series of gummer
pads, 526, are carried in a rotary holder, 525, which is carried on the hollow
sleeve 528, that has thereon the ratchet-wheel 527. Said ratchet-wheel sleeve is

page_text: fitted to turn on the stud 529, that is fixed in the slide bracket 545, as shown in the
sectional view Fig. 46. The ratchet-wheel 527 is actuated by the pawl 530,
(similar to pawl 517,) and is carried by the stud 536, which is fixed in a bracket, 537,
that is adjustably fixed to the standard 486, by a screw and washer 538.
spring, 539, connected to the standard 486 by a screw 540, serves to hold pawl 530
in engagement with the ratchet-wheel 527. The slide bracket 545 is secured to the
slide 546 by means of screws 547, and these parts together constitute one element
of mechanism, and may be made integral, if so desired. Said slide is actuated by
the connecting-rod 550, which takes hold of stud 552, secured to the slide by
screw 553. The rod has a slot, 551, formed in the upper end thereof, and a
spring, 555, (carried on the hook 556 fixed in the stud or bushing 552, and the
pin 557 fixed in the rod 550,) serves to normally hold said stud against the bottom
end of said slot. The lower end of the connecting-rod 550 is connected by a stud
to the arm 558, which is fixed by its hub 559 to the right-hand end of the first
rock-shaft 119, as will be seen from Figs. 1, 65 and 130.
The mode of operation of this apparatus is as follows: The gum bottle 508,
having been filled with the usual solution of gum, is placed in position as shown in
Fig. 45, between the posts 507, and with the mouth thereof resting on the ledge 509.
The gun now flows down, filling the box up to the level of the hottle mouth. The
gum roll 515 has an intermittent rotary movement imparted thereto by the rock-
shaft 119, through the connections above described, including the slide bracket 545
and pawl 517, which pawl engages with the ratchet-wheel 513. The gauge, or
roll scraper, 500, is next adjusted to regulate the amount of gum adhering to
the gum roll, being adjusted by the thumb screw 502. The gummer pads 526
being located on the periphery of the wheel 525, are successively brought into
working position below the axis of said wheel or holder, and afterward to the
upper side thereof, said holder being turned forward on each upward movement
thereof, as will be readily understood from Figs. 44, 45 and 46. Fig. 45 shows
the slide bracket in its uppermost position, with one of the gummer pads
taking gum from the gum roll 515, as indicated by solid lines in the drawing ;
the dotted lines 525 show the holder lowered, thus bringing one of said pads to
bear on the end-flap of the uppermost blank of the pile 303, which pile rests on the
plate 270 of the blank-feed mechanism. The ratchet 527 has as many teeth or
catches formed thereon as there are gum pads 526; being six in this case.
The
pawl 530, being fixed to the standard 486, is stationary, and operates, on each
upward movement of the slide bracket, to turn the holder 525 one-sixth of a
revolution; so that on every upward movement of the said bracket, one gummer
pad face takes gum from the gum roll, and on every downward movement thereof
another said face delivers gum to the then topmost blank of the pile 303; the
spring 555, hereinbefore mentioned, accommodates the operation of this apparatus
to the varying height of the said pile of blanks.
THE BLANK FEEDING MECHANISM.
This portion of the machine is shown in a plan view in Fig. 28. Fig. 29, drawn
in projection thereto, illustrates the operation of the same. Figs. 30 to 34, inclusive,
are views showing the construction in detail of this mechanism." Figs. 33 and 34 ore
sectional views illustrative of the operation of engaging, and disengaging the feed-
pawls and holding pawls. I designates the framework of this mechanism, which is
conveniently made box-shaped, as shown, to contain the intermediate shafts and
gearing. Said framework, F, rests on ledge 65 of column B, and is secured to said
column by screws 307, as shown in Fig. 32. F' is a top plate, which forms the cover
of frame or box F, and to the top of which the usual guides are fixed for holding
the blanks in proper position laterally. These guides are four in number, arranged
in two pairs, of which one pair is at the front, (marked 260 and 200%) and one at
the back, marked 261 and 261ª. All of said guides may, and usually do have a
slight adjustment on the top plate to accommodate slight variations in the blanks,

page_text: •
being held down in the usual manner by screws and washers, 316", Fig. 28, sub-
stantially as shown. Guides 260 are shown supported by brackets 262, as in Fig. 29.
The back guides 261 rise directly from their bases 263, but have in this case, as
they usually do in practice, an outwardly-projecting arm, 264, for holding the
separator device. This device consists of an arm or lever, 265, pivoted to said
arm 264 at 266, and each provided with a separator finger 267, which may be
clamped therein by a screw, 268. Springs 269 are provided to produce a slight
downward pressure of the fingers onto the pile of blanks, being connected to
arms 265 and posts 261 (see Fig. 32). Spring separator-fingers 308 are secured to
the front-guides by washers 309, and screws 310, and pass through slots formed in
the inner side of said front-guides, as shown. 303 designates a pile of envelope-
blanks in proper position for the gummers, 227 and 227, Fig. 24, to take up
blanks therefrom; the pile, as shown, being nearly exhausted. 270 is one of the
blank-supporting plates, shown in position for holding up pile 303, and near the
uppermost point of its vertical travel. 271 is a similar blank-supporting plate, which
is shown in position for receiving the pile of blanks 304. These blank-supporting
plates are respectively each upheld by a similar set of vertically-movable plate-
lifters, 272 and 273. Each set of lifters consists of three rods arranged as shown in
Figs. 28 and 30. For communicating a simultaneous and equal vertical motion to all
the lifters in a set, a horizontal rod, 274 for lifters 272, and 275 for lifters 273,
is provided and arranged to slide in bearings formed in the frame F. Underneath
and at right angles to rods 274 and 275 are the revolving shafts 276 and 277 and a
fixed shaft 278, carrying a system of gearing intermediate to said rods and lifters.
Each rod has thereon rack teeth 279, which mesh into a gear on shaft 276, and into
another on shaft 278. In Fig. 30 a part of rod 274 is broken away the better to show
the arrangement of the gearing. Rod 279 meshes into gear 280, which is fixed on
shaft 276, and into gear 281 which revolves loosely on shaft 278. Shaft 276 has two
gears, 282 and 283, each of which meshes into rack teeth 311 on one of the front
lifters 273, (see Fig. 30) and gear 281 has secured thereto a gear, 284, that meshes into
similar rack teeth 312 on the rear lifter 273. Rod 274 meshes into gear 285, (similar
to gear 280,) which is loosely fitted on shaft 276, and into gear 286 on shaft 278,
which is similar to gear 281. Gear 285 has fixed thereto a gear, 287, which meshes
into another and similar one, 288, fixed on shaft 277. This shaft has two gears, 289
and 290, fixed thereon, each of which meshes into rack teeth in one of the front
lifters 272, and gear 286 has another, 291, (similar to 284) which meshes into
rack teeth 314 on the rear lifter 272. The relative proportions of the members of
these systems of gearing are such that when either of the rods 274 and 275 are
drawn forward the set of lifters connected thereto will all be raised np equally.
It is desirable, also, that said rods shall move somewhat faster than the lifters, so
that the operator can control the elevation of the pile with greater ease and accuracy.
The rear lifters 272 and 273 have horizontal arms, 315, the ends of which are
fitted to slide vertically in slots in the upright guide post 316, which is secured
to plate F by screws as shown. The rods 274 and 275 have ratchet-teeth, 292,
on their upper sides, whereby they are automatically fed forward. For this purpose
a rock-shaft, 293, carried on a bracket 294, and having arms 295, is provided with
feeding-pawls 296, and with holding-pawls 297, which operate in the usual manner.
Said shaft has an oscillating motion imparted thereto through connecting-rod 298
and arm 299, from some suitable menuber, (as the picker-spindle,) of the envelope-
machine. The extent of said motion should be sufficient to move pawl 296 through
the distance of one of the teeth 292, and a little in excess to insure certainty of
action. The rods 274 and 275 are each provided with a handle, 300, whereby they
may be operated by hand. Said rods have been described as having a horizontal
sliding movement; but they may also have, and as herein shown do have, a rotary
motion of about ninety degrees for the purpose of disengaging the pawls from the
notches 292, handle 300 being then in the position shown in Fig. 34. In order that
said rotary motion may not also disengage said rods and the gears 280 and 285, the
rack-teeth 279 are made to extend around these rods about one-half of their circum-

page_text: ference, as shown in the section of rod 274, Figs. 33 and 34. By turning rod 2741
from the position shown in Fig. 33 to the position shown in Fig. 34, teeth 292 are
turned down to one side and surface 301 brought under the feeding and holding
pawls. Then said rod may be moved by hand forward or backward at any point of
its stroke and thrown into engagement with the pawls by simply turning it
back to its original position-that is, with handle 300 hanging down, as in
Figs. 31 and 33.
The "connecting-rod" 208 is shown constructed to serve the special purpose of
automatically feeding the blanks up to a given height only. To this end said rod has
a hook, 317, at its upper end, for engaging with a corresponding hook, 231, on one
(or more) of the picker-spindles 213. The rod 298 is made laterally movable at its
upper end, being carried in a bearing, 318, on column B, and normally held out by
a spring and plug, 319, Fig. 32. The particular construction and arrangement of
these parts is such that when the picker-hook 231 descends below a given point, as
line a e. Fig. 29, it will catch the hook 317 of rod 298 and draw up the same, thus
actuating shaft 293 and causing the blank-plate to be elevated. But if the picker-
hook does not descend to said line a e, then the hook-shaped end, 317, of rod 298, is
simply pressed toward one side and thus fails to act, until the removal of blanks from
the pile 303 shall permit of such engagement and action as aforesaid.
The blank-supporting plates 270 and 271 may have any shape to adapt them for
being upheld by the lifters and for holding the pile of blanks, said shape depending
somewhat, of course, on the shape of the blanks they are to hold.
In Fig. 28,
270 designates a plate of convenient form, having fingers, 302, for supporting the end-
flaps 305. Suitable springs not shown, are or may be in practice, fixed to the under-
side of the plates, to engage with the lifter-rods, and thus to hold the plates with
some little force in their proper position on the top of said lifters. The operation
of this blank-feeding mechanism is as follows: One of the blank-supporting plates,
as 270, is placed in position 271 on the lifters 272, which then stand down. A
pile of blanks, as 303, is then placed on plate 270, and the plate with said pile on it
is lifted up until the top of said pile is at the point shown in Fig. 29. The
envelope-machine being now started up, the blanks are taken up one by one from
the pile, the plate being fed up in the meantime by means of the mechanism above
described. While this is going on, the operator places plate 271 in position on
the lifters 273, and places a pile of blanks, 30, on said plate. Rod 275 is now
drawn forward, lifting plate 271 until pile 304 reaches plate 270, when said
plate 270 is pulled out, letting the remainder of pile 303 rest on pile 304. Rod 274
is then turned to disengage the pawls 296 and 297 and is slid back, thus lowering
the lifters 272, when plate 270 is again placed on them and another pile of blanks
on that, to be fed up as before. In this way the machine may be run continuously,
the blanks being fed at convenient intervals."
THE BLANK CREASING MECHANISM.
The frame or upright, 566, for carrying the creaser-slide, is fitted to the front
wall 49, of the column B, in a usual manner, being secured thereto by the holding
screws 565. (See Figs. 1, 2, 4, 66 and 67.) Said upright 566 has formed thereon
the guides, 561, to which is fitted the creaser-slide 595, which has a vertical move-
ment imparted to it by the creaser eccentric 104, on the main cam shaft 70, through
the several arms and connecting-rods hereinafter described. Slide 595 has an
adjusting bracket or block 581, which is adjusted by screw 584; a holding
screw 582, and washer 583, serve to hold said bracket in place. The angle-lever or
rocker arm, 576, is pivoted in the creaser upright 506, by pin 577. The creaser
arm link 578 connects the adjusting bracket 581 and said arm 576, being furnished
with the pivot pins 579 and 580, for that purpose. The creaser connecting-rod 573
is pivoted to arm 576, by pin 575, and to the inside creaser arm 568, by pin 574.
The creaser arm 568 is clamped onto the creaser arm shaft 571, by a clamp screw 570,
The frame or upright, 566, for carrying the creaser-slide, is fitted to the front
wall 49, of the column B, in a usual manner, being secured thereto by the holding
screws 565. (See Figs. 1, 2, 4, 66 and 67.) Said upright 566 has formed thereon
the guides, 561, to which is fitted the creaser-slide 595, which has a vertical move-
ment imparted to it by the creaser eccentric 104, on the main cam shaft 70, through
the several arms and connecting-rods hereinafter described. Slide 595 has an
adjusting bracket or block 581, which is adjusted by screw 584; a holding
screw 582, and washer 583, serve to hold said bracket in place. The angle-lever or
rocker arm, 576, is pivoted in the creaser upright 566, by pin 577. The creaser
arm link 578 connects the adjusting bracket 581 and said arm 576, being furnished
with the pivot pins 579 and 580, for that purpose. The creaser connecting-rod 573
is pivoted to arm 576, by pin 575, and to the inside creaser arm 568, by pin 574.
The creaser arm 568 is clamped onto the creaser arm shaft 571, by a clamp screw 570,

page_text: and may also be keyed thereto, since in practice this fastening should be securely
made. Shaft 571 also carries the outside creaser arm 567, whereby this shaft is
actuated; said arm being clamped thereto by clamp screw 569, and connected to
eccentric rod 560 by pin 572. The eccentric rod 560 passes through the hole or
slot 22; formed in the top plate 7, of the main bed A, and has at its lower end the
creaser eccentric strap 561, which is fitted to the creaser eccentric 104, on the main
cam shaft 70. The creaser-die base or bed 613 rests at its inner end on the column B,
and at its outer end on the frame 566, it being held in place thereon by screws not
shown, which pass through the holes 614, (Fig. 47,) in said bed 613. The creaser-
slide 595 has formed in the lower end thereof the dovetail groove 596, to receive the
dovetail 596, formed on the creaser-blade-holder 605; said holder having the
creaser-blades 606 secured thereto by the screws 607. The inside lower edges of
the said creaser-blades 606 are bevelled, and the outside of the same concaved, as best
shown in Fig. 48; these blades are preferably constructed of steel and should be well-
tempered; said blade-holder 605, together with said blades 606, constitutes the
"upper creasing-die." The lower creasing-die consists of the side blocks 615, the
end blocks 616, the die bed 613, and the minor details supporting said blocks on said
bed. The blocks 615 and 616 are fitted to turn on the hinge-pins, 617, of the
hinge-plates 618; said hinges being adjustably secured to the creaser-bed 613, by
the holding-screws 619. The side blocks 615 have secured thereon the lower side
spring plates 631, and the upper side spring plates 632, by the screws 635. The end
blocks 616 have similarly secured thereto the lower spring plates 633, and the upper
spring plates 634, by the screws 635"; the said side and end blocks are yieldingly
upheld by the springs 620, their upward movement being limited by stop surfaces
at 620, Figs. 48, 51-53, and 61.
The numeral 306, Figs. 51-53, designates an envelope-blank being operated upon.
The upper and lower spring plates above referred to are shown on a larger scale
in Fig. 61; and the form and construction thereof may be best understood by con-
sulting said view. As shown, the lower spring plates rest on the side and end blocks,
and are secured thereto in the manner above described; they consist of the flat
portion 630, the angular portion 633, and the curved edge 629. The upper spring
plates consist of the flat portion 626, (resting on the portion, 630, of the lower
plates,) the angular portion 627, and the rounded edge 628. The said plates are, in
practice, made of spring steel; and as best shown in Figs. 47 and 48, the edges and
angular portions thereof are split or sawed, forming numerous fingers; the cuts of
one plate alternating with the cuts of the other plate so that one finger 636 of an
upper plate shall rest on two of the fingers 637 of a lower plate. This construction
secures a very perfect operation of the creasing die, since the narrow fingers, 636
and 637, constitute, in effect, independent springs, each bearing against the paper as
in Fig. 61, and thus folding the sheet equally close to the edge of blade 606,
throughout the whole length of said.blade. The operation of creasing an envelope-
blank by means of the above-described mechanism will be understood by referring
to Figs. 49 to 53 inclusive. A sheet of paper of proper blank form, 306, as shown
in Fig. 49, is placed on the lower die, as in Fig. 51, resting on the edge 628. The
upper die is then brought down onto the paper, the edges of said die pressing said
paper down against the curved portion or edge, 629, of the lower spring plates, as
in Fig. 52, and at a little distance from the rounded edge or border, 628, of the
upper spring plate. On now continuing the downward motion of said die, the
edge 629 is carried by the blocks downward and sidewise, as clearly shown
in Figs. 53 and 61, closing the edge 628 up against the side of the creaser-blade
as it presses the paper into the corner formed by, and between the upper and lower
spring plates. This operation being simultaneously performed on the four sides, the
blank (shown plain in Fig. 49) is folded up as shown in Fig. 50, and without
tearing or breaking the paper. It will be understood that during this operation the
blank is held by its side-flaps adhering to the seal and back-flap pickers respectively,
in proper position at the creasing station, C³ of the machine.

page_text: This portion of the machine consists of the upper and lower platens, and the means
for actuating the same. But the upper platen, or "platen proper, is also the block
or blade-holder, 603, of the upper creaser-die, which block is carried on the lower end
of the creaser-slide 595, as herein before described. Said slide, therefore, constitutes
an element of two mechanisms, which, however, are herein constructed and arranged
for conjoint operation. In practice, said platen 605 is furnished on the underside
thereof with a suitable blanket, 685, Fig. 61, of paper or papier-maché, or other
material usually used for like purposes by printers.
The type to be printed from may be secured in any well-known manner to the
platen 676, of the printing-slide 676. Usually, however, I use to print from an
electrotype. 683, which is secured in the usual manner (as by nails not shown)
to the block 682, that is secured by screws 684 to the removable "forme" or
chase 680. See Figs. 54, 55 and 61. Said chase is held in place on the said
platen by screws 681, which pass through the flange, 680, of said platen, as shown
in Fig. 63. The printing-slide 676 is fitted for vertical movement in the channel 59
(see Figs. 9, 11, 12 and 54,) formed in the right-hand side of the column B,
being held therein by slide-straps 677 and 678, that are secured to said column
by the screws 679. Said printing-slide is actuated by the printing-cam 102, on
the main cam shaft 70, through the following intermediate devices: The printing
cam roll 648 is carried on the cam roll stud 650; said stud being made fast in
the arm 649, by the nut 651. Said arm 649 is carried on the printing shaft or
stud 652 said shaft being fixed in the hole 39, in the wall 5 of the main bed A.
A spring, 653, serves to hold said cam roll normally in contact with the cam 102:
Said shaft 652 also carries the link arm 654, which is pivoted on the stud 656,
that is fixed in the printing-slide link, 655, by means of the nut 657. The said
link passes through the hole 20, formed in the top plate 7 of the bed A, the upper
end thereof being carried on the printing-slide adjustment eccentric 665: said
eccentric being, bored to receive the eccentric-supporting stud 666, which is firmly
screwed into the slide 676. The eccentric arm or lever 667 is adjustably secured
to the eccentric 665, by the clamp screw 668, the hub of said arm being split on
one side for that purpose. The eccentric arm 667 has at its upper end the index
pin 669, said pin being provided with the spring 670 and knob 671. (See Fig. 56.)
Holes, 672 and 678, are formed in the printing-slide 676 to receive the point of
the index pin 669. When the eccentric arm 667 is thrown over to the right-hand
and the index pin 669 is inserted in hole 672, as shown in Figs. 54 and 56, the
eccentric 665 is in the position shown by the dotted line in Fig. 54, being locked in
said position by said index pin, and the mechanism is ready to print. If arm 667 is
thrown over to the left, to the position indicated by the dotted lines in Fig. 54, and
the index pin is inserted in hole 673, the slide 676 is lowered by the eccentric 665 to
a position below the printing point; said eccentric being again locked by said indox
pin. By this means the operator may at any time instantly throw down the type
forme into an inoperative position. The operation of the above-described printing
mechanism is as follows: An envelope-blank having been carried by the pickers to
the proper position between the upper and lower creasing-dies, the upper die is now
brought down forcibly onto said blank, thereby holding the blank firmly in place
by means of the creasing-blades, as before set forth; and while said die remains on
the paper,
the type 683, being previously inked, is brought up against, and prints the
blank, as shown in Fig. 61. The operation of the slide 676 is so timed by the proper
shaping of the printing-cam 102 that the printing is completed and the type with-
drawn from contact with the blank while this is firmly held between the creasing-
dies. This feature, in practice, enables the printing to be performed very rapidly
without any displacement of the blank on the pickers.

page_text: The ink-fountain, 686, has its seat at 60, on the column B, being secured thereto by
screws 687, and the lower edge of said fountain resting on the ledge, 61, of said
column. The ink-fountain roll 699 is carried on the ink-fountain-roll shaft 700, said
shaft being journalled in the end walls 702 and 703, of the ink-fountain 686. Said
shaft 700 has affixed to its outer end the ratchet-wheel 701, through which it is
rotated by means of the pawl 708. The ink-fountain gauge-plate or roll-
scraper, 688, is secured to the inclined front wall, 704, of said fountain, by the
holding-screws 689, and is provided with the adjusting-screws 690; the office of said
gauge-plate being to regulate the quantity of ink carried on said roll 699. The ink-
fountain-pawl, 706, is operated by the ink-fountain-pawl eccentric 707, on the
ink-fountain cam shaft 708; said shaft also carries the transfer cams 709 and 710.
and the worm gear 711. The ink-transfer roll, 716, is carried on the transfer roll
shaft 717, said shaft having its bearings in the slides 718; these slides are provided
with the movable caps 719; springs 720 serving to hold said caps in their proper
place and yet allow the transfer roll 716 to recede under a certain pressure. The
springs 721, which bear on the spring pins 722 fixed in the slides, serve to hold said
slides always in contact with the transfer cams 709 and 710, said cams imparting a
vertical movement thereto. When the slides 718 are allowed by the revolving of
said cams!709 and 710 to assume their lowest position, being forced down by the
springs 721, the transfer roll 716 is brought in contact with the ink-fountain roll 699,
(as shown in dotted lines in Fig. 57,) from which the said transfer roll receives a
coating of ink. When in the course of their revolution the transfer cams have
raised the slides 718 to their uppermost point, the transfer roll is brought in contact
with the cylinder 751, to which it delivers the ink it has received from the ink-
fountain roll 699. The stop-pin bosses 723, formed on the ink-fountain 686, form
bearings for the stop-pins 724, these pins being provided with the stop-pin springs 725.
The holes 726, in the slides 718, are provided to receive the stop-pins 724 when the
operator wishes to lock the slides, as in Fig. 58, to prevent the transfer roll 716
taking ink from the ink-fountain roll 699. Fig. 60 is a fragmentary view showing
one of the stop-pins 724 drawn out, and one of the slides 718 free to be operated by
one of the transfer cams, assisted by spring 721. As shown in Fig. 60, the stop-
pin 724 is provided with the knob 727, which has inserted therein a pin, 728. When
by means of the knob 727 the stop-pin 724 has been fully drawn out and turned to
one side, so that pin 728 shall not re-enter hole 729 in the boss 723, but shall rest on
the face of said boss, the stop-pin 724 is prevented from entering hole 726, in
slide 718; said slide is then free to be operated as aforesaid. The ink-distributer
roll 737 is carried on the distributer roll-shaft 738, said shaft being journalled in the
vertically-movable shaft bearings 739; said bearings being provided with the bearing-
springs 740, (see Fig. 58, Sheet 17). The oscillating ink-distributer-roll cam 745
is carried on the supporting screw stud 746, which passes through the hub of said
cam; an arm, 747, is formed on said hub, said arm being forked at the end thereof
to receive the cam-actuating pin 748, which is fixed in the pawl 706. A grooved
cam roll, 736, is made fast to the outer end of the distributer-roll shaft 738. The
inclined or spirally-formed working edge or face, 745ª, Fig. 62, of the cam 745, is
fitted to work in the groove of said cam roll 736. The said face 745, of cam 745,
being at an angle to the axis of the shaft 738, as the cam is oscillated by the
pawl 706, through the pin 748, it gives a forward and backward movement to the
distributer-roll 737, thereby distributing the ink evenly over the surface of the ink-
distributing cylinder or roll 751. This operation is strictly analogous to the
distribution of ink in ordinary printing presses, and hence need not herein be further
set forth.. The ink-distributing cylinder 751 is carried on the distributing-cylinder
shaft 752; said shaft being carried in the bearings 753 and 754. Said shaft 752 also

page_text: carries the spiral gear 755. The ink-fountain vertical shaft, 766, passes through the
hole 21, formed in the top plate 7 of the bed A, and has an upper bearing, 767, and
a lower bearing, 768. Said shaft has secured thereto at its upper end the spiral
gear 769, which meshes with the spiral gear 755; and said shaft also carries the
worm 770, that meshes with the worm gear 751. The vertical shaft 766 has secured
thereto at its lower end the mitre gear 773, meshing with the mitre gear 774 carried
on the ink-fountain pulley shaft 775; said shaft 775 being carried in the bushing 776,
which in turn has its bearing in the main bed A, at 40, (see Fig. 5, Sheet 4).
Shaft 775 is rotated by the ink-fountain pulley 777, which receives its power from
the main cam shaft 70, through the belt 778, (see Fig. 1). The inking-roll 788, on
the inking-roll shaft 789, is carried by the forked inking-roll carrier or lever 790.
Said carrier 790 is held in the inking-roll carrier clamp, 795, by means of the
clamp screw 796; said clamp being pivoted at the upper end of the inking-arm or
lever 798, by the pin 797; the carrier spring 799 is provided to give a downward
pressure to the said carrier. The inking-arm 798, pivoted in the inking-arm
bearing 800, by the inking-arm stud 801, passes through the hole 23, formed in the
top plate 7 of the main bed A, and has at its lower end the inking-arm cam roll 802,
which is secured to said arm 798 by the cam roll stud 803. Said cam roll 802 bears
on the inking roll cam 108, on the main cam shaft 70, whereby said roll is actuated
in proper time. The inking-arm bearing 800 is secured to the top plate 7 of the
main bed A. The inking-arm 798 is provided with the pull spring 804, the
opposite end of which is carried by a hook screwed into the column B, as shown in
Fig. 57.
THE FOLDING MECHANISM.
This portion of the machine will be best understood by comparison of Figs. 16,
66, 67, and 69 to 73 inclusive; it comprises the "folding turret," and folding
apparatus operating in connection therewith to fold the back-flap and the seal-flap.
Referring to said figures, (and also in a general way to Figs. 1, 2 and 3,) it will be
seen that bearing sleeve 826 carrying the folding turret is affixed by its flange 832 to
the part 58 of the side wall 54 of column B (by screws not shown,) its tenon 833
being fitted into the hole 57 (Fig. 10) in said column. The turret-shaft 823 is carried
in said sleeve, as shown best in Fig. 69, and at its enlarged outer end 823* is con-
nected by pin 828 to the tubular shaft 827 that carries the "spider" or frame 830 of
the folding turret proper. Said shaft 823 is actuated from shaft 186 by closely-fitted
gearing. The driven bevel gear 824 is keyed fast to the inner end of said shaft 823, being
held thereon by a nut, 825; it meshes with the corresponding driving gear 816, which
is fitted to slide on shaft 186, and on the key or spline 817 thereof, being held in place
in proper mesh with gear 824 by the adjusting nut 818, which is shown to be a clamp-
nut or collar, held together by clamp-screws, as shown in Fig. 36. By this means, as
the teeth of gears 824 and 816 wear away, the gear 816 may be moved upward to bring
the said teeth into a firm bearing again; for in practice these gears should run without
any play or back-lash. Said pair of gears are" skew bevels," the axis of shaft 823 being
about one-half of an inch rearward in the machine of the axis of shaft 186; this arrange-
ment is adopted to permit a better arrangement of the fold plates, 831, on the turret
spider 830, as shown in Figs. 71 and 73; said plates being set forward, in their line
of movement, of a radius 834, (Fig. 73,) for the purpose of co-acting with the back-
flap folder, as hereinafter more fully set forth.
The fold turret spider, 830, consists of the hub and the four arms referred to
as 830", 830, 830°, and 8301 respectively; each arm carrying one of the series of
folding-plates 831, 831, 831b, and 831. Each folding-plate has hinged thereto at
each end, the end-fold wings right and left designated by 836 and 837 respectively;
which wings have adjustable shoes, right 838 and left 838", for gauging the
"thickness
of the edge of the folded envelope, being adjusted by set screws 839,
and binding screws 835, (Fig. 70,) in a well-known manner. The hubs 840 of said
wings are bored to receive studs 841, carrying cam rolls 842 which run in the
F

page_text: grooves 845 of the oscillating end-fold cams 843 and 844, respectively, whereby said
end wings are actuated. Said cam roll studs are held in place by the binding-
screws 840, which clamp said hubs 840, (which are split on one side thereof,) firmly.
to the stem of said studs. Thickness collars 816 and 847 separate cams 843 and 844
from the spider 830; the outer cam being held in its proper place on sleeve 827 by
a washer 829 and nut 829ª. The end-fold cams 843 and 844 have a rotary-
reciprocating movement imparted thereto by connecting-rods 848 and 849, which
rods are secured to said cams by means of screws 850 which pass through
bushings 851. Said connecting-rods are connected at their lower ends to
studs 82, which are fixed in arms 159 on the second rock-shaft 153, by nuts 853.
This rocker 153 is actuated from shaft 119 by arm 140, connecting-rod 160, and
arm 166 on said second rocker, the arms having pins 162 and 161, respectively, for
said rod. The back folding wing 856 is carried by the arm or lever 858, which is
carried on shaft. 859; said arm 858 passes through the hole 24, formed in the top
plate 7 of the bed A, and has at its lower end a cam-roll 860, which bears on back-
fold cam 110, on main cam shaft 70; which cam (see Fig. 67,) operates to draw
forward said folder, (toward the right-hand in this figure,) the work of folding the
back-flap being performed by the spring 857. Said shaft 859 is an eccentric one,
carried at its inner end in bearing 66 of column B, and at its outer end in the clamp-
bearing 67, affixed to bed A by screws 68 and 68; by loosening screw 68, said shaft
may be turned to throw the back-fold plate 856 either toward or from the fold turret.
Said plate 856 is adjustably attached to the upper end, 861, of arm 858, by a
stud, 862, which passes through said upper end and is held therein by nut 863. The
form and construction of the end-fold cams 843 and 844 will be best understood by
reference to Fig. 124.
The seal-folder consists of the arm 866, which has secured across its forked ends
the folder-bar 867. The movement of this bar is shown by dotted line 865, in Figs. 71
and 73. Arm 866 is adjustably-secured to a carrier arm 868, see Figs. 67, 71
and 73. Said carrier has formed thereon an arm, 869, to one side of which, 870, is
fastened one end of a spring, 871, the opposite end which is made fast to the top
plate 7, of the bed A. The carrier arm or lever, 875, is forked at its upper end, and is
provided with the shaft 876, (see Fig. 69,) on which shaft, and between the said forks
of the arm 875, is loosely fitted the seal fold carrier 868. The arm 875 is carried on
the seal-folder eccentric stud 42, said stud being journalled in the bearing 41, that is
formed in the wall 6, of the main bed. The lower part of arm 875 passes through
the hole 26, formed in the top plate 7 of the bed A, and carries at its end the cam
roll 877, which bears on the seal-fold carrier cam 107. The seal folding arm, 878,
is also carried on the eccentric 42, and is formed at its upper end, 879, to bear on the
arm 869 of the carrier 868. The office of spring 871 is to always hold the arm 869
in contact with the said face 879. Arm 878 carries at its lower end the cam roll 880,
bearing on the seal folding cam 106, on the main cam shaft 70. The horizontal
movement of the seal folder 866 is derived from the cam 107 through the arm 875;
and the vertical movement thereof from the cain 106, through the armi 878; and these
two movements are so timed by the corresponding shaping of said cams as to
produce the required movement, as set forth, of the seal-fold bar 867.
THE TRANSFER MECHANISM.
3
The operative parts of this mechanism are actuated from the second rock-shaft 153.
The lower transfer arm 181 has a hub, 182, which is fitted onto said rock-shaft 153,
and is secured thereto by the pin 183. Arm 181 has secured to its outer end, by
the screw stud 934, the transfer arm connecting rod 935, (Fig. 16, Sheet 7,) said rod
being connected to the upper transfer arm 930, by means of the stud 931, Fig. 3,
Sheet 3. The arm 93 is adjustably secured to the transfer shaft 932, by the transfer
arm binding screw 933, (Fig. 3,) the hub of said arm being split on one side for that
purpose; the shaft 932 has its bearing, 393, Fig. 36, in the gum-box bracket 391,
the sleeve 393 and the base 394 forming a part of said bearing.

page_text: The upper nipper 886 is pivoted to the hollow sleeve 902 by the upper nipper
stud 887, which passes through the ears 899, on said sleeve 902; the said
nipper 886 has secured thereto one end of a spring, SSS, the other end of said
spring being carried by the arm 885, the function of said spring being to hold up
the outer end of nipper 886; said nipper also has formed thereon a stop-arm 884,
to limit the upward movement thereof. The lower nipper has at its outer end the
hollow stud 892, (sometimes provided with the rubber covering 893, (see Fig. 79,)
and also has formed integral therewith the sleeve S94, bored to loosely fit on the
transfer finger shaft 919; also the hub 895, bored to fit the rock-shaft 917, to
which it is secured by the pin 896. The transfer finger or pusher 920 is secured
to the fixed shaft or stud 919, by means of the pin 918; the transfer finger 921
is also secured to shaft 919 by a pin 922. The transfer finger connecting-arm 923,
which is formed integral with the finger 921, is pivoted on the stud 925, said
stud being fixed in the arm 924 by the nut 926. The arm 924 is connected to
the outer end of shaft 932, as to a stud, by means of the screw 927 and the
washer 928; said shaft. 932 has a rocking movement imparted to it by the second
rock-shaft 153, through the connections hereinbefore described. The transfer
adjustable arm 889 is adjustably clamped to the shaft 932, by the clamp screw 890,
the hub of said arm being split to permit of this. The arm 900, formed on the
sleeve 902, is adjustably secured to arm 889, by means of the screws and
washers 901, said screws passing through slots, (indicated by dotted lines 901", in
Figs. 75 and 76,) in said arm 900, and being screwed firmly into arm 889. The
sleeve 902 is bored to receive the rock-shaft 917, which is fitted to turn freely in said
sleeve; the arm 911 is secured to the inner end of said shaft, by a pin 911ª, in the
usual manner; said arm having a stud, 916, secured to its outer ond by the nut 916",
said stud carrying one end of the transfer finger connecting-rod 903. The transfer
friction clamp, 904, is in two parts, hinged together on the stud 905, said stud
being provided with the nut 9.6. The friction clamp 904 is provided with the
friction leathers 907, which bear on the outer surface of the sleeve 393; the
clamp screw 908, the spring 909, and the check-nut 910 are provided for regulating
the pressure of said friction. The clamp furnished with the leathers as set forth,
is fittted to the reduced part 393, of the said sleeve 393. The rocking movement of
shaft 917 is imparted thereto by the shaft 932, through the clamp 904, the con-
necting-rod 903, and rock-shaft arm 911, pinned to said rock-shaft 917. The
stop 912, secured to the arm 900 by the holding-screws 913, and provided with
the stop screw 914 and the stop screw check-nut 915, serves to limit the rocking
movement of the rock-shaft 917 in its bearing 902.
•
When the arm 889 is carried up as in Fig. 77, the said connections revolve
shaft 917 in its said bearing to throw up the nipper 886 as in Fig. 77, at the
same time throwing down nipper 891, and drawing back the fingers 920 and 921,
as there shown. At this time the folding-plate 831 has brought an envelope, 306,
in position above the trough 938, ready to be taken hold of by said nippers
and deposited in said trough. Next, the reverse movement of said shaft 932
operates to close said nippers or gripper fingers 886 and 891 onto the envelope
as in Fig. 76, and firmly grip the same. Continuing its motion, the arm 889
carries the closed nippers down to the position shown in Fig. 78; at this point
the envelope is brought to position 7, while the preceding one is pushed along by the
fingers 920 921 to the position p, between the fingers of the carrier, as in Fig. 78.
The transfer trough 938 is supported on a base, 939, that is securely fastened
in place on top of the framework of the machine, by means of ordinary screws
not shown. Said trough 938 is made fast to said base by screws not shown, and
is provided with the trough-caps 943 and 944, which are secured to the edges of
said trough by the cap-screws 945. The said caps have formed thereon ears, to
receive the pivot pins 947, 947ª, 947, and 947, carrying the detent-latches or
pawls 946, 946, 946, and 946, respectively. The pawl springs 948, 948, 948, and 948°
are provided to lightly hold down said pawls; said springs being secured to the

page_text: caps 943 and 944, by the holding-screws 949. Said pawls are arranged in pairs;
the two designated by the numerals 946 and 946ª comprising the first pair; and
the two designated 946 and 946°, the second pair. In Figs. 76 and 77, the
numeral 831 designates one of the folding-plates of the folding-turret, and 306
designates a folded envelope thereon. When in the operation of the machine as
aforesaid the nippers 886 and 891 have grasped the envelope 306 by the seal-flap,
as shown in Fig. 76, (said envelopes being still carried on the folding-plate 831,
and held in place thereon by the end-fold wings,) as the end-fold wings release
said envelope 306, the nippers transfer it to the position r, shown in Fig. 78 below
the detent pawls 946 and 946ª; the envelope being still in the grasp of the nippers.
The nippers now release the envelope, and return to the position shown in Fig. 77,
ready to grasp another envelope. The first pair of pawls serve to prevent the
return of the envelope, should it happen to adhere to the nippers in any way.
The nippers now take another envelope, and, as before, carry it to the transfer
trough; the transfer fingers 920 and 921 at the same time push the first envelope
beyond the second pair of pawls, (whose office is the same as that of the first pair,)
and into the endless carrier, allowing it to rest on one of the carrier fingers 956,
as shown in Figs. 78 and 80. The grooves 937 are formed in the trough 938,
to provide for the free passage of the transfer fingers 920 and 921, as these
project below the envelope, as illustrated in Figs. 76 and 78.
THE ENDLESS CARRIER.
This element of the machine consists in an endless belt or apron, 955, provided
with fingers for holding the envelopes. Said fingers, 956, are formed or fixed on
the finger-base 957, which is provided with the envelope-stops 958, that overlap
the bases of the adjacent fingers, as shown in Figs. 82 and 83. The driving-
bar 959, having the teeth 960 and the driver-pins 961 formed thereon, is secured
to the base 957 by screws 962; this clamps the endless belt 955 firmly between
said parts, the teeth or pins 960 being firmly imbedded in the substance of the
belt. The envelope-blanks having, one by one in rapid succession, been gummed,
creased, printed and folded, are taken by the transfer mechanism from the folding-
turret and carried to the transfer-trough as completed envelopes; from the said
trough they are delivered to the endless carrier at the position p, Fig. 78. From
this point the envelopes pass upward, and come down on the rear side of the
carrier, pass between the guides 982 and 983, and forward of the rear guide 981,
until they reach the position 7, Fig. 86, where they stand on the envelope-
way 985, at the entrance to the packing-box. The said carrier, which is of
sufficient length to allow the gum and the printing ink to thoroughly dry, is
driven by an apparatus hereinafter described, and is supported or suspended
by a pulley that is placed above the machine. Said pulley may be supported by
a shaft carried in hangers depending from the ceiling of the room, in a well-known
manner; which shaft should be arranged, in practice, to be vertically-adjustable,
for the purpose of taking up the stretch of the belt 955, as this becomes lengthened
by long use. At its lower end, said carrier passes under the driving gear or
sleeve 966, which has the driving teeth 964 for engaging with the driving pins 961,
and is carried on a fixed shaft or stud, 965, that is supported by the hearing 1095
formed on the packing-box frame 1072; said shaft being held in place by a
set-screw 1097", or by other suitable means. The driving gear ratchet 967 is
securely clamped to the sleeve 966, by means of the clamp-screw 968, the hub of
said ratchet being split on one side for that purpose. In practice, it is found
desirable to control the movement of the sleeve 966 by a frictional resistance, for
which purpose clamp said sleeve between the leather friction-washer 972 fitted
onto the stud 965, against the bearing 1095, and a similar washer, 971, that is
fitted onto the said stud 965, between the hub of the ratchet 967 and the
friction-collar 973; a-sheet-metal spring-washer 974, between said collar and the

page_text: ALTIOW
the washer $74 to spring under the pressure of the nut 975.
The carrier driving-sleeve 966 is driven by the end-fold rocker 167, through the
driving-pawl 977, which engages with the ratchet 967, being held thereon by
gravity; the said pawl is carried by the stud 978, which is fixed in the ear 979,
formed on the arm 159 of said rocker 167, this rocker being carried on the second
rock-shaft 153. The operation of said carrier-driving apparatus will be readily
understood without further description, the pawl having a simple reciprocating
movement, and acting in a well-known manner.
PLACING AND COUNTING MECHANISM.
A few details of this mechanism are carried by the bracket 1042, which is fitted
on and secured to the shelf 27 that is formed on the rear side of the top plate, 7,
of the main bed A. But the greater portion of said mechanism is carried by the
packing-box bed-plate 1070, which is fully shown in Figs. 85, 85%, and 85ª, and
is secured on the main bed A, adjoining the aforesaid part 1042. The envelope-
plunger slide 1035 is carried by said bracket 1042, being fitted to move between
suitable ways or guides thereon; as herein shown, these ways comprise the upper
guide 1043 and the lower guide 1044, said guides being fixed to the bracket by
screws as shown. The envelope-plunger, 1025, is pivoted to the slide 1035, by the
screw stud 1026; said plunger has two stops, the upper stop 1027, which is
formed on the slide 1035, and the lower stop 1028, which is secured to the
slide 1035 by the screw 1029. (See Fig. 84.) The plunger 1025, for the purpose
of cushioning the same, is provided with the leather strap or buffer 1030, which
is secured by screws, as shown, on the projecting end or stop-arm, 1031, of said.
plunger 1025. The slide 1035 is usually provided with a friction device con-
sisting of the cap 1036, the leather 1037, the screw 1038, and the spring 1039.
By turning the screw, the tension of the spring may be adjusted, for regulating
the pressure of the clamp and leather on the lower guide 1044, and thus control
the resistance of the friction device to the slide movement. The purpose of that
resistance is to furnish a means for operating the envelope-plunger on its pivot 1026.
The envelope-plunger arm 1049 is carried on the envelope-plunger shaft 1050,
which turns in the bearing 30, (Fig. 85,) in the rear wall, 4, of the main bed A,
and in a second bearing, 31, formed on the wall, 6, of said bed A. Said shaft 1050
is actuated forwardly by a spring, 1057, which is connected by a pin, 1056, to
the arm 1055, that is secured by the pin 1052 to said shaft. The opposite end
of said envelope-plunger spring is connected to a pin, 1058, fixed in the rear
wall of the bed A. The envelope-plunger 1025 is operated backwardly by the
cam 148 on the first rock-shaft; which cam acts through the roll 1048, which is
carried on a stud, 1047, fixed in an arm, 1046, that is fixed by its hub and clamp-
screw 1045, to shaft 1050, adjacent to bearing 31. The face of said cam 148 is
shaped to impart to said plunger the proper movement. The cam 148 is secured
to shaft 119 by its hub 149 and the clamp-screw 150. See Figs. 84 and 85.
The envelope-plunger arm, 1049, is adjustably-secured to the outer end of the
shaft 1050 by means of the clamp-screws 1049, and is pivotally-connected at its
upper end to the envelope-plunger 1025, by means of the stud 1053, fixed in said
arm by the nut 1054, and werks in the slot 1034 in said plunger.

The nature of the said construction is such that when the parts are assembled
substantially as shown and described, a reciprocating movement of the arm 1049
imparts a * four-motion movement to the forward end 1025* of the plunger 1025.
This is for the purpose of permitting the plunger to go forward (toward the left-
hand in Fig. 84,) while the chain 955 stands still, and to return while said chain
is going forward. As shown in said Fig. 84, said plunger is in the middle of its
forward movement; the pressure of arm 1049 on stud 1053 keeping the arm. 1031.

page_text: in said chains. This movement being completed, the plunger then goes back to
its original position, ready for the next operation.
THE ENVELOPE PLACER.
The first rock-shaft, 119, also carries the envelope-placer arm 143, whose hub 143
is bored to fit loosely on said rock-shaft. The curved face, 144, of said arm 143 bears
on the placer-slide roll 995, which is carried on the stud 996, fixed in said placer-
slide 989, (see Figs. 84 and 85). The envelope-placer cam 109 is carried on the
main cam shaft 70, and actuates said arm 143 through the placer-cam-roll 145, which
is carried by a stud, 146, fixed in the arm 143 by the nut 147. The slide 989 is
provided with the spring 991, which with the arm 143 operates the said slide; the
inner end of said spring being supported by the hook 992, which is made fast in the
main bed A; the outer end being carried by the tension-look 993, said hook being
carried by the arm 989b of said placer-slide, and being provided with the adjusting
thumb-unt 994, the said spring passing through the opening 33, formed in the wall 4
of the bed A, as shown in Fig 85. The placer-slide is fitted to slide on a guide or
rib, 997, on the bed 1070, (see Figs. 84 to 85, inclusive,) which rib fits in the
groove 989 formed in said slide. At its inner or forward end said slide rests on the
shelf 7 of bed A; and at its outer or rearward end is supported by two caps or
gibs, 990, which are held by screws 990 to the under side of said bed 1070. This
bed 1070 (secured to bed A by screws in holes 1071°) has a shelf or ledge, 984, on
which the envelope-way 985 is set. being held thereon by screws not shown. The
purpose of said part 985 is to furnish a guide or track onto which the envelope may
be delivered by the chain and accessory devices, and on which the envelope may be
slid along into the packing-box. Accordingly, the track 985", Fig. 86, on which the
lower edge of the envelope 306 rests, coincides in height and alignment with the lower
surface of the packing-box. The envelope-placer, 986, is carried by the placer-
slide 989, being secured thereto by the holding-screw 987. The counting-arm, 998, is
carried on the counting-arm stud 999, and is provided with one or more counting-
fingers 1000, which are fitted to normally pass through slots 988 formed in the
placer 986. Said counting-arm is actuated in one direction by the cam 1008, which
acts on the roll 1001, that is carried on the stud 1002; it is reversely actuated, first
by an envelope carried against said fingers 1000, and then by the releaser-cam 1009,
which is affixed by screw 1010 to the arm 989 of the placer-slide, and which strikes
the cam, 1011, on said arm 998.
The mode of operation of said devices is illustrated in Figs. 85, 86 and 86. On the
backward movement of said placer and placer-slide, shown by dotted lines in Fig. 86,
the cam 1008, acting on roll 1001, throws arm 998 into the position shown in
Fig. 86, with the fingers 1000 standing back of the way or track 985", and with the
cam 1011 standing clearly below the cam 1009. The envelope being now brought
by the chain nearly up to the way 985", as in Fig. 86, the placer on its forward
movement carries it against the fingers 1000, and thus throws the arm 998 into the
position shown in Fig. 86, where the cam 1011 stands above the line of cam 1009,
as there shown; and on further forward movement of the placer, the cam 1011
strikes cam 1009 as in Fig. 85, and (owing to the steep inclination of their working-
faces) instantly throws the fingers forward of said way 985, thus releasing the
envelope from its clamped position between said placer and counting-fingers. This
operation sets the counting devices ready to turn the "stop-wheel" 1020, but does
not actually turn that wheel; this is done on the outward stroke of the cam 1008,
which acts in a positive manner on the arm 998, which is connected to actuate said
wheel. By this means each complete movement of the machine causes the stop-wheel
to be turned, provided an envelope is forward of the placer; but in the absence of
the envelope at that point, the fingers 1000 are not thrown back, the cam 1011
remains below cam 1009, and..the arm .998. remains idle. Thus, the presence or

said bed. Said wheel has a ratchet-wheel 1019 whereby it is turned. The connections
for actuating the wheel 1020 from the arm 998 consist of the pawl-arm 1016,
carried on the hub 1012, Figs. 101 and 104, of the wheel 1020, said arm being
pivoted at its lower end to the connecting-rod 1004, by the screw-stud 1005. The
counting-pawl 1017 is carried on the arm 1016, by the pin 1018, and operates the
ratchet 1019. The arm 1016 is actuated by the rod 1004 pivoted thereto at 1005,
and to arm 998 at 1003.

the tension-hooks 1134 and 1135, said hooks being provided with the adjusting thumb-
nuts 1141 and 1142; the bracket 395, which is screwed fast to the gum-plate-
bracket 391, is provided to carry the said hooks 1134 and 1135. See Figs. 2, 3, 36
and 100.
The packing-box upper hook, 1136, is secured by holding-screws 1137 to the upper
hook-arm 1138, said arm being carried on the upper hook-arm shaft 1139, and
secured thereto by the set-screw 1140. The packing-box lower hook, 1143, is secured
by holding-screws 1144 to the lower hook-arm 1145, said arm being carried on the
lower hook-arm shaft 1146, and secured thereto by the set-screws 11.97. The packing-
box-hook spring, 1148, is held in place by the holding-screws 1149; see Fig. 98.
The packing-box cam-arm 1151 is fixed to the shaft 1146; the packing-box-hook let-
off or latch-cam, 1152, is pivoted to the arm 1153 by the pin 1154, and is provided
with the spring 1155, said arm 1153 being pivoted to the packing-box frame by the
pivot-screw 1156. The connecting-rod 1157 is connected to the arm 1153 by the
screw-stud 1158, and by stud 1159 to the car 170, which is formed on the arm 159,
of the end-fold-rocker 167, that is carried on the second rock-shaft 153.
The packing-box retaining-hook 1166, Fig. 97, is carried on the pin 1167, and is
provided with the spring 1168. The upper guide-block 1160 is secured to the packing-
box frame by the screws 1161, and the lower guide-block 1162 is secured to said
frame by the screws 1163. The packing-box front-plate, 1075, is secured to said box
by the screw 1075, said plate being backed up by the upper and lower blocking
pieces, or envelope-stops, 1076 and 1076"; the said front plate has the projection 1077
formed thereon. See Figs. 90 to 98 inclusive. The envelope-supporting plate, 1100,
of the packing-box is secured to the frame 1072 by the screws 1101. The packing-
box end-plate, 1104, is secured to the packing-box frame by the screws 1105. The
bunch-plunger proper, 1179, is provided with the upper guide-shoe 1180, and the
lower guide-shoe 1181, loosely fitted to the stud 1182, said stud being fixed in

nut 1201, the stud 1200, carrying the cam-roll 1202, which bears on the band-knock-
off cam 1383, which is hereinafter described in connection with the banding
mechanism.

page_text: The completed envelopes having been delivered to the endless-carrier or
chain, said carrier being operated by the endless-carrier driving mechanism, as
hereinbefore described, said envelopes are carried upward in the direction indicated
by the arrow in Fig. 78, over an ordinary supporting-pulley not shown, and down on
the opposite side, between the right-hand and left-hand guides 982 and 983 and
forward of the outer or rear guide 981. The envelope-placer 986, which is operated
as before described, pushes the said envelopes one by one slightly forward to their
proper position on the envelope-way 985, the upper edges of said envelopes resting
against the projection 1077 of the front-plate 1075, as shown in Fig. 78 from this
point the said envelopes, after being counted as hereinbefore set forth, are pushed by
the envelope-plunger 1025 into the packing-box, and rest with their edges on the
supporting-plate 1100. The operation of the packing-plates and of the course of an
envelope entering said box, is best shown in Figs. 87, 88 and 89, which views show
said box in horizontal section. Fig. 87 shows a number of envelopes, 1102, in the
packing-box, the first packing-plate, 1086, being fully closed and holding said
envelopes in place; the second packing-plate, 1090, is fully open, and the envelope-
plunger, 1025, is pushing an envelope, 306, into said box; the first packing-plate
now opens to admit of the full entrance of envelope 306, as in the next fig. In
Fig. 88 both packing-plates are shown fully open, and the plunger 1025 has pushed
the envelope 306 into the packing-box and against the cn l-plate 1104, said plate thus
acting as a stop for the envelope. In Fig. 89 both the first and second packing-plates
are shown fully closed, they having carried the last-entered envelope to place; and
the plunger 1025 is shown returning to its position, preparatory to bringing forward
another envelope. The first and second packing-plates are operated by the packing-
plate cams 171 and 177, hereinbefore described, said cams being constructed and
timed suitably therefor. The above operations are repeated until twenty-five envelopes
have been packed in the said packing-box, when the bunch-plunger 1179 pushes the
said bunch of envelopes out of the packing-box and into the bunch-trough 1575; a
band being placed thereon as the bunch passes from the packing-box to said trough;
the said banding operation being accomplished in a manner hereinafter described.
The operation of the bunch-plunger, 1179, is as follows: The pull-spring 1207
operates to turn the shaft. 1199 in its bearing, through the cam-roll-arm 1203, the
turning of said shaft giving a forward movement to the said plunger 1179, through
the bunch-plunger arm 1194. Each time an envelope is taken by the placer 986 and
is placed upon the envelope-way 985, in the manner above described, the ratchet-
plate 1020, (which is fixed to or formed on the ratchet 1019,) is turned on the stud 1022
(by means of said ratchet and the connections hereinbefore described) through the
one twenty-fifth part of a complete revolution. The form and timing of the cam 111
is such as to allow the plunger 1179 to be thrown forward (by the means above
described) on the completion of each movement of the plate 1020. The stop-hook 1185,
coming in contact with the plate 1020, prevents the further forward movement
of said plunger, which is immediately returned to its position by the cam 111, (the
forward movement of the plunger, in this case, being very slight, usually about the
one thirty-second part of an inch :) on the completion of the twenty-fifth movement,
or one complete revolution of the ratchet-plate 1020, at which time twenty-five
envelopes have been placed in the packing-box by the envelope-plunger 1025, and
the plate 1020 is in the position shown in Figs. 101 and 104; the notch 1021,
formed in the plate 1020, has been brought into line with the stop-hook 1185, the
plunger 1179 is thrown forward by the means above described, pushing the twenty-
five envelopes out of the packing-box into the bunch-trough 1575; the bunch-
plunger 1179 being immediately returned to its original position by means of the
cam 111, as before.

page_text: For convenience of description, this mechanism may be considered in two divisions,
consisting of the band-placing apparatus and the band-making apparatus. The latter
takes a previously prepared tub of band material, feeds the same to the shears, cuts
off the band and delivers this to the band-placing apparatus. Said placing apparatus
receives the band thus made, carries it to, and hold the same expanded in, position to
be placed at the proper time on the bunch of envelopes. The construction of this
portion of the banding mechanism will be best understood from Figs. 126 to 131,
inclusive.
The movable band-carrying finger 1307 is riveted to the band-carrier slide 1308;
the opposite and shorter band-carrying fingers, 1309 and 1310, are riveted to the
band-carrier arm 1325. Said carrier-slide 1308 is provided with the spring 1311;
said spring being connected at one end by the pin 1312, which is fixed in the
slide 1308, the opposite end being connected to the pin 1313, that is fixed in the
slide-cap 1314. Said slide-cap is secured to the band-carrier-arm 1325, by the holding-
screws 1315, which arm is provided with the stop-screws 1326 and 1327, the
holding-screw 1328, and the washer 1329; said holding-screws serving to adjustably
secure said carrier-arm to the arm 1331, whose hub 1331" is bored to turn freely on
the fixed band-carrier shaft or stud 1338, it being held in place on said shaft by the
collars 1339 and 1340; and said collars being fixed on the shaft 1338 by the set
screws 1341 and 1342 respectively. The ears 1332, formed on the hub 1331", are
provided with the chain-pin 1333, carrying the chain 1334; said chain having at its
lower end the pin 1835, which carries one end of the band-carrier-spring 1336,
whose opposite end is held by the spring-hook 1337, that is fixed in the main bed A,
near the base thereof. See Fig. 3.
The band-pusher, 1351, is provided with the holding-screw 1352, and the washer 1353,
by which it is adjustably-secured to the band-pusher-arm 1354, whose hub, 1354ª,
is fitted freely on the shaft 1338. Said pusher is moved in one direction by
the spring 1355 that is connected at one end to pin 1357 in hub 1331, and at the
other end to the pin 1356 in the hub 1354". A leather washer, 1343, is usually
provided to cushion the blow of the hub 1354" as the same is thrown forward toward
the left-hand, in Fig. 126. The arm 1354 has formed thereon the lug 1368, which
stands forward of the point of the outside let-off' arm 1365, as best shown in Fig. 129.
The arm 1365 is fixed by its hub 1366 and pin 1367 to the let-off shaft 1363. (See
Figs. 126 and 127.) The inside let-off arm 1361, (see Fig. 131,) has a hub 1362,
fixed on the shaft 1363, by the set-screw 1364, said shaft 1363 having its bearing in
the bed, 1345, of the banding mechanism. Said arm 1361 engages with the
stop-arm 1413 which is formed on the banding-cam shaft sleeve 1412.
The band-knock-off connecting-rod 1371 is pivoted to the arm 1365 by the screw-
stud or pin 1372; and said rod is connected by the stud or pin 1373, (Fig. 84,)
to the lower knock-off arm 1375, said stud being held in place by the nut 1374.
The said arm 1375 passes through the opening 32, which is formed for that purpose
in the rear wall 4 of the bed A, and is fixed by the pin 1376 or otherwise to the
lower end of the band-knock-off shaft or stud 1382, Fig. 85. Said shaft 1382 has its
bearing 1041 (Fig. 85b) in the bed-plate 1070 of the packing mechanism, but passes
freely through the hole 29, formed in the shelf 27 of the main bed A. (See Fig. 5.)
The band-knock-off cam-lever 1381 is fixed or formed on the upper end of said
shaft 1382, and has adjustably secured thereto (by screws and washers 1384) the
band-knock-off cam 1383; which cam is adjusted on said arm by the adjusting-
screw 1385, usually having a check-nut, 1386. The knock-off cam is actuated by the
roll 1202 on the bunch-plunger lever 1194, as shown in Figs. 108 and 109, and
hereinbefore referred to.
The band-carrier shaft or stud 1338 is supported in the hole 1348, (Figs. 116

page_text: and 117) formed in the bed or frame 1345, being fixed therein by the set-screw 1346,
Fig. 126. Said bed 1345 rests on the ledge or shaft 27, and against the wall 28,
at the rear side of the bed A, (sec Fig. 7) and is shown in detail in said Figs. 116
and 117, with the bracket 1495 attached thereto by screws 1496. The hub 1331°, of
the band-carrier arm 1331, has formed thereon the connecting-rod arm 1331,
provided with the stad 1391, (held in place by nut 1392,) for the band-carrier
connecting-rod 1393; which rod passes through the opening 34, formed in the wall 4
of the bed A, and is connected by the stud 1394, (held in place by the nut 1395,)
to the band-carrier rock-arm 1396, whose hub 1397 is fitted to turn freely on the
band-carrier rock-shaft 1398; this shaft being carried in the bearings 1399 and 1400,
that are supported within the main bed A, by screws 1405, one of which is shown by
dotted lines in Fig. 125. Said hub 1397 has formed thereon another arm, 1401,
provided with the stud 1402, (held in place by nut 1403,) carrying the cam-roll 1404,
that bears on the banding-cam 1411. See Figs. 115, and 125 to 131. The
banding-cam shaft 1421 is carried in the right-hand bearing 1422 and the left-hand
bearing 1423, which bearings are secured to the main bed A, by screws not shown;
the bearing 1422 has a set-screw, 1424, for holding in place therein the said
shaft 1421. The banding-cam 1411 is formed on the banding-cam-sleeve 1412,
(shown in detail in Fig. 125.) on which are also formed various other cams and
parts hereinafter mentioned. The banding-cam gear 1429 is carried on the sleeve 1412
between the leather friction washers 1430 and 1431, which are clamped between.
the fixed friction-plate or surface 1526, (Fig. 125,) and the movable friction-
plate 1432, that is forced against said washer 1430 by the friction-spring-plate 1433,
and the friction-adjusting-nut 1434. See Fig. 130. The banding-pinion shaft
bearing 1443 is secured to the wall 5 of the main bed or frame A, by the holding-
screws, 1444; the hub of said bearing passing through the hole 38 formed in the
said wall. The pinion-shaft 1445 is carried in the bearing 1443, and has on its

mechanism driving-pulley 1454 is fitted to turn freely on shaft 1445, and its
hub 1454 is bored to receive the pawl 1455, and the spring 1456 for actuating
said pawl said pawl engaging with the ratchet-teeth 1457, formed on the hub, 1458,
of said hand-wheel 1452. The pulley 1454 is driven by an ordinary band or belt 781,
(Fig. 65,) from the pulley-face 779, (Fig. 1) on the sleeve 750; which sleeve
extends inwardly from the pulley 777 that is fixed on shaft 775. See Figs. 1, 63,
65 and 65ª. Said shaft 775 is driven by the band 778, from the pulley 75, as
hereinbefore stated in connection with the inking mechanism. The arrangement
of driving mechanism here described permits the banding mechanism to be operated
forwardly by hand, whether or not the pulley 1454 is revolving, the pawl 1455
yielding whenever the hand-wheel 1452 is turned faster than said pulley 1454.
THE BAND-MAKING APPARATUS.
are
The band-tube feed-roll bracket 1495 is secured, as before stated, to the bed 1345
by the holding-screws 1496. The band-tube upper feed-roll shaft, 1486, is provided
with the knob 1487, pinned to said shaft by a pin 1488; said shaft is carried by
the bearings 1489 and 1490, which are fitted to slide vertically in the rectangular
slots, 1497 and 1498, respectively, formed in the said bracket 1495, and
provided with the bearing-springs 1499 and 14992, the, bearing-spring-washers 1500
and 1500, and the bearing-spring tension-screws 1501 and 1501; which screws
are carried in the bearing-caps 1502 and 1503, that are fixed on the bracket 1495
by the cap-screws 1504. (See Figs. 114 to 120, and 125.) The shaft 1486 carries
the sleeve 1491, fixed thereon by the pin 1491; which sleeve has formed or
assembled thereon the band-feed rolls 1491, the shuttle-guide flanges 1492, and the
gear 1493.
The band-tube lower feed-roll shaft, 1519, has its bearings in the
bed 1345 and in the bracket 1495, and passes freely through the opening 36 in
the wall 4 of the main bed A. Said shaft 1519 carries freely thereon the sleeve 1506,

page_text: which has formed thereon the band-tube lower feed-rolls 1507, the gear 1508
meshing with and driving the gear 1493; also the ratchet-wheel 1509, whereby said
sleeve and feed-rolls are driven. The band-tube feed-pawl 1510, which engages with
the ratchet 1509, is carried on the pawl-stud 1511, that is fixed by the nut 1512 in
the feed-pawl arm 1513. A spring 1525 (Fig. 119,) is secured to the arm 1513, and
bears on a flattened part of the pawl 1510, so as to hold said pawl in engagement
with the ratchet 1509. Said arm 1513 is secured to shaft 1519, by the pin 1514;
and is actuated backward by the pawl-arm-spring 1515, that is connected at one end
to the hook 1516 on said arm, and at the other end to a hook or bracket 1495. The
movement of the pawl-arm is regulated by a stop, 1517, that is adjustably-fixed on
the bracket 1495, by the screw 1518. (See Fig. 118.) The shaft 1519 has
secured at its inner end the band-feed arm 1520, which has a stud 1521, (fixed therein
by nut 1522,) that carries cam-roll 1523; which roll bears on the band-feed
cam 124, that is formed on the banding-cam-shaft sleeve 1412. The rotation of
cam 1524 imparts a forward movement to arm 1520, and through shaft 1519 and
through the pawl-arm, pawl and ratchet, to the feed-rolls 1491 and 1507; the
return movement being made by the spring 1515, as aforesaid.
"
OPERATION OF THE BANDING MECHANISM.
A diagram or time-chart" of the cam movements of this mechanism is shown
in Fig. 15. A rocking movement is imparted to the band-carrier by the cam 1411,
through the arms and connections hereinbeforo described. When the bunch-
plunger-arm, 1194, is allowed, as before described, to throw forward the
bunch-plunger 1179, it also operates through the cam-roll 1202, the cam 1383,
and lever 1381, to turn the shaft 1382 in its bearings; and the turning of said
shaft operates, through the arm 1375, the connecting-rod 1371, the arm 1365,
and the shaft 1363, to disengage the let-off arm 1361 from the stop-
arm 1413, (Figs. 130 and 131,) on sleeve 1412. As soon as this disengagement takes
place, the sleeve 1412 and the cains thereon are revolved on the shaft 1421 by the
frictional driving apparatus hereinbefore described, through one full revolution,
and until said let-off arm again strikes said stop-arm and thus arrests said movement.
During said revolution, said cams on sleeve 1412 severally perform the work
for which they are designed. Said sleeve is allowed to make but one revolution
each time it is started; since the arm 1361 is immediately returned to place, in the
path of said stop-arm 1413. The cam 1411, formed on the sleeve 1412, operates
through the cam-roll 1404 and the connections before described, to turn the band-
carrier arm 1331, on the shaft 1338, down to one side as in Figs. 126 and 127; at
the lower part of said movement the slide 1308 strikes the stop 1316, as shown
in said figs., and thus closes the band-carrier-finger 1307 against or nearly to the
band-carrier-fingers 1309 and 1310. The band-tube 1485 is now fed forward in a
manner hereinafter described, the band-carrier-fingers receiving the end of the said
tube; the band-shears are next operated by the shear-cam 1554, through the
connections described, to cut off a band, which is deposited on the said band-carrier
fingers. As the band-carrier arm now returns to its first or upright position, as in
Figs. 126 and 127, the spring 1311 operates to separate the said band-carrier-fingers,
which thus expand the said band 1476, thereon, as illustrated by dotted lines in
Fig. 105.
The operation of placing a band on a bunch of envelopes is best illustrated in
Figs. 105, 106 and 107. The desired number of envelopes having been placed in
the packing-box by the envelope-plunger 1025, the bunch-plunger 1179 pushes said
envelopes out of said box in the mauner herein before described. At the same time
that the bunch-plunger moves forward, the arm 1365 engages with the lug 1368,
formed on the hub 1354 of the band-pusher-arm 1354; this causes tho said hub to
slide on the shaft 1338, carrying with it the band-pusher 1351, which pushes the
band 1476 off from the band-carrier fingers, and places it on the bunch of envelopes
as they leave the packing-box, as shown in Fig. 106. In Fig. 107 the bunch is

page_text: shown pushed fully out of the packing-box, and having a band in place thereon. In
Fig. 114 said bunch is shown deposited in the bunch-trough 1575, forward of the
bunch-pusher 1572.
The operation of feeding the hand-tube onto the band-carrier-fingers is best shown
in Fig. 120. The tube is slipped by hand over the tube-opener 1484 of the band-
shuttle, and between the band-shuttle-rolls 1469 and the upper and lower feed-
rolls 1491 and 1507; the paper guides 1478 and 1479 serving to prevent the
band-tube from passing between the two front shuttle-rolls, as it might sometimes do
in the absence of said guides. The tube material is held firmly between said rolls by
reason of the springs 1499 and 1499, herein before described. The band-tube is now
ready to be automatically fed forward; this being accomplished by the band-tube
feed-cam 1524 and its connections hereinbefore described. The rocking of the
shaft 1519 operates through the feed-pawl arm 1513, and the feed-pawl 1510, which
engages with the ratchet 1509, to intermittently revolve the band-feed rolls. The
four small band-shuttle-rolls being fitted to freely turn on the pivot screws 1471,
(see Fig. 121,) and the feed-rolls being firmly pressed against the tube material by
said springs, the turning of said feed-rolls acts to draw forward the band-tube over
the shuttle, leaving this always in the same position. The pressure of the said feed-
rolls on the band-tube is regulated by the thumb-screws 1501 and 1501". The normal
longitudinal position of the shuttle between the feed-rolls is maintained by reason
of the entering of said feed-rolls between the small shuttle-rolls, as well shown in
Fig. 120.
The upper band-shear-blade 1528 is screwed to the upper band-shear-arm 1530,
by the upper blade-screws 1529; the arm 1530 is carried on the upper shear-arm-
bushing 1531, which is secured to the bracket 1495 by the screw-stud 1532. See
Figs. 114 and 115, and 118 to 12. The lower band-shear-blade 1533 is screwed to
the lower band-shear-arm 1535, by the lower blade-screws 1534; the arm 1535 is
carried on the lower shear-arm-bushing 1536, which is screwed to the bracket 1495
by the screw-stud 1537. The upper shear-arm 1530 has formed thereon the upper-
shear-segment 1538, whose teeth mesh with those of the segment 1539, which is
formed on the lower-shear-arm 1535, as will be understood from Figs. 119 and 120.
The shear-guard 1540 is provided with the band-tube guide-arms 1541 and 1542,
and is secured to the bracket 1495 by the guard-holding screws 1543.
The shears are operated by a connecting-rod 1547, which is connected to arm 1544,
that is formed on the lower shear and has the stud 1545 fixed therein by the
nut 1546; said rod passes through the opening 35, formed in the wall 4 of the main
bed, and at its inner end is connected by stud 1548 and nut 1549 to the shear-cam.
roll-arm 1550. See Figs. 130 and 131. Said arm carries on the stud 1551, (held
therein by nut 1552,) the cam-roll 1553, which bears on the shear-cam 1554, that is
formed on the banding-cam-sleeve 1412. The arm 1550 is fixed by its hub 1555,
and pin 1556, to the band-carrier rock-shaft 1398; which shaft is thus turned
forwardly by said arm 1550. The opposite movement of said shaft 1398 and
arm 1550 is effected by the pull-spring 1564, which is connected by chain 1563 to
the bunch-pusher-arm that is also fixed on said shaft, as shown in Figs. 125 and 130,
and hereinafter again referred to.
THE BAND-TUBE SHUTTLE.
This part, (see Figs. 120 to 123,) consists of the shuttle-frame 1463; four band-
shuttle rolls 1469, which are carried on the points of the roll-carrying screws 1471,
that are screwed into the frame 1463; one upper shuttle-spring 1480, secured to the
frame 1463 by two holding-screws 1481; one lower shuttle-spring 1482, secured to
the frame 1463 by two holding-screws 1483; the upper and lower paper-guides 1478
and 1479; and the band-tube-opener 1484. Said opener serves to separate the
upper and lower sides of the band-tube 1485, (Fig 120,) as this tube comes from
the roll, 1475, of previously prepared tubing; which roll is supported by an arbor

page_text: or reel, in a well-known manner. The shuttle is supported by and between the
feed-rolls 1491 and 1507, being guided as to its lateral position by the flanges 1492,
as best indicated in Fig. 125.
THE BUNCH-DELIVERY APPARATUS.
The bunch-pusher arm 1560 is secured by means of the clamp-screw 1561 to the
band-carrier rock-shaft 1398, and is provided with the pin 1562, to which is
connected one end of the chain 1563, which chain passes through the opening 37
in the main bed A, and at its opposite end is connected to the pusher-actuating
spring 1564, that is connected to the pin 1565 fixed in the bed 1345. The bunch-
pusher or plate 1572. is carried by the arm 1570, having the slot 1573 formed therein
for the bottom plate 1574 of the bunch-trough 1575. The arm 1570 is carried by
the pusher-slide 1569, which is fitted to slide on the bed 1345, and in a recess or
channel formed in the underside of said trough 1575; said slide has in the end
thereof a notch, 1571, to receive the head of the pusher-arm 1560. The bunch-
trough 1575 rests at the right-hand side of the machine, on the top plate 7 of the
main bed A, to which it is secured by screws, not shown, in a well-known manner.
Said trough is provided with the bunch-stop hooks or catches 1576 and 1577,
having the retaining-springs 1580 and 1581, respectively; said springs are carried
by the spring-hooks 1582 and 1583 in the side walls of the said trough 1575. See
Figs. 114, 115 and 125. In Fig. 114, a bunch of envelopes, 1584, is shown in the
delivery-trough, forward of the bunch-pusher 1572.
The operation of this apparatus is as follows: The shaft 1398 is oscillated in one
direction by the cam 1554 (on the sleeve 1412) acting through the connections
hereinbefore described, and in the other direction by said spring 1564, shown in
dotted lines in Fig. 125. The bunch of envelopes, 1584, having been deposited in
the bunch-receiving trough 1575, as shown in Fig. 114, the bunch-pusher is moved
forward as above described, and carries said bunch forward against the stop-
hooks 1576 and 1577. The said hooks recede under the pressure of said bunch and
allow it to pass, and then return to place close behind the bunch, preventing this
from falling back, and thus leaving the space behind said hooks for the reception
of next succeeding bunch, when the operation as above outlined is repeated.
The operator takes the bunches from the trough, and packs them in boxes for
shipment.
THE AUTOMATIC STOP-MOTION.
This mechanism comprises two portions, one being for the envelope-plunger, ard
the other for the bunch-plunger, and they will be described in this order.
The stop-motion arm 1211 is fixed by pin 1212 on the envelope-plunger rock-
shaft 1050. A stud, 1213, in the end of said arm 1211, carries one end of the
connecting-rod 1214, the opposite end of said rod being connected by the stud 1215
(which is held therein by nut 1216 and the washer 1217 see Figs. 111 and 112)
to the pawl-arm 1221, whose hub 1222 is fitted to turn freely on hub 1242 of the
friction-plate of disc 1240. The stop-motion pawl 1223 is carried on the stud 1215,
and is provided with the pawl-spring 1224, said spring being carried on the spring-
hooks 1225 and 1226. The outer end of the envelope-stop-motion shaft 1228 is
supported by the bracket 1229, which is secured to the main bed A by the bracket-
screws 1230; the inner end of shaft 1228 has its bearing, 125, formed on the
flange, 123, of the left-hand bearing, 122, of the first rock-shaft 119. The shaft 1228
has secured to its inner edge the mitre gear 1231 by a pin in the usual manner.
The stop-motion guard disc or plate 1236 is fixed by its hub 1237 and pin 1238 to
the shaft 1228. Said disc 1236 has formed in its edge the notch 1239. The
envelope-stop-motion friction-disc 1240 has the similar notch 1241 formed in the edge
thereof, and has two contact-pins, 1249 and 1250, which are or may be formed
integral with said dise; its hub 1242 being fitted freely on the said shaft 1228. The
friction-clamps 1243 are provided with the leathers 1244, which bear
on the

page_text: laterally-projecting hub 1242 of the friction-disc 1240; said clamps are also
provided with the clamp-screw 1245, the clamp-screw-nut 1246, the friction-clamp-
spring 1247, and the friction-clamp-stud 1248, which stud is fixed in the bracket 1229.
The stop-motion latch-arm 1251 is fixed on the shaft 1228 by a pin in the usual
manner said arm 1221 is provided with the stud 1252 and the stud-nut 1253, for
carrying the stop-motion latch 1255. This latch has a lower bearing 1256, formed
on the flange, 1264, of the left-hand bearing, 1263, of the stop or shipper-rod 1251;
a spring, 1254, one end of which is carried on the stud 1252, and the opposite end by
a hook fixed in the bearing 1256, is provided to impart a downward pressure to the
said latch 1255. The stop-rod 1261 has a right-hand bearing 1262, and a left-hand
bearing 1263, fixed in the walls 5 and 6 respectively of the main bed A. (See
Fig. 68.) The said stop-rod is provided with the stop-rod-collar 1265, pinned to
said rod, and the stop-rod-spring 1206; said rod has near its left-hand end the
notch 1267 formed therein to receive the point of said latch 1255.
The operation of this stop-motion apparatus as follows: The envelope-plunger 1025
receives its backward and forward motion from the shaft 1050, as hereinbefore
described, the office of said plunger being to push the completed envelopes one by
one out of the endless-carrier and into the packing-box. The machine is set in
operation by throwing the pulley 72 into engagement with the friction-cone 74, by
means of either of the shipper-handles 92 and 93; this at the same time, through
the arm 94 (see Figs. 65 and 68) pushes back the stop-rod 1261 until the latch 1255
drops into the notch 1267 formed in the said rod. The machine being now in
operation, and having pushed an envelope into the said packing-box, the plunger
immediately starts on its backward movement; the connecting-rod 1214 simultaneously
moving forward (being carried by the arm 1211), the pawl-arm 1221 strikes the
contact-pin 1249, causing the friction-disc 1240 to turn on the shaft 1228, until the
notch 1241 of said disc 1240 is brought into line with the notch 1239, formed in
the edge of the shaft-disc 1236. (See Fig. 113.) The plunger is now fully back,
and immediately starts on its next forward movement, the rod 1214 at the same
time moving in the opposite directien; the pawl-arm 1221 strikes the contact-
pin 1250, thus returning the disc 1240 to place. This return is thus accomplished
provided that the plunger 1025 moves fully forward; but should the movement of
said plunger be obstructed in any manner, as, for instance, by disarranged envelopes,
then the plunger does not move fully forward, the arm 1221 is not thrown back far
enough to strike the contact-pin 1250, the dise 1240 remains in its position, and
the notches 1241 and 1239 are still in line, as shown in Fig. 113. As the plunger
now moves backward, the rod 1214 moves forward, causing the pawl 1223 to slide on
the edge of the discs; the notches 1241 and 1239 being in line, the point of said
pawl drops into said notches. The pawl 1223 cannot engage with the notches 1239
and 1241 until these are brought into line; at any other time said pawl may pass
over said notches, the edge of one disc acting as a bridge to carry the pawl over the
notch in the other disc. When the said notches are in line, the rod 1214, on
continuing its forward movement, turns the discs by means of the said pawl; as the
disc 1236 is fixed to the shaft 1228, by pin 1238, said shaft is turned in connection
therewith, causing the arm 1251 to lift the latch 1255 out of said notch 1267, and
thus release the said stop-rod, which is then thrown forward by the spring 1266;
this movement of said stop-rod operates through the arm 94 to turn the shaft $7,
and said shaft through the arms 88 and 89 disengages the pulley 72 from the
friction-cone 74 in a manner hereinbefore described, thereby stopping the machine.
THE AUTOMATIC BUNCH-PLUNGER STOP-MOTION.
This mechanism is similar in construction and operation to the envelope-plunger
stop-motion above described. The stud 1271 is fixed in the bunch-plunger-arm 1194,
and carries one end of the connecting-rod 1272, whose opposite end is connected to
the stud 1273 that is fixed by the nut 1274 in the pawl-arm 1278. This arm is carried

page_text: on the hub 1295 of the friction-disc 1294; the stop-motion pawl 1279 is carried on
the stud 1273, and is held by the pawl-spring 1280 against the edges of the stop-
motion disc. The bunch-plunger stop-motion shaft 1285 has its upper bearing in the
bracket 1286, which is secured to the top plate 7 of the main bed A by the bracket-
screws 1287; the lower bearing, 126, of said shaft 1285 is formed on the flange, 123,
of the left-hand bearing, 122, of the first rock-shaft 119. At the lower end of the
shaft 1285 is secured the mitre gear 1288, which meshes with the gear 1231_that_is
fixed on the shaft 1228. The bunch-plunger stop-motion disc 1293 is pinned to the
shaft 1285, and has formed in the edge thereof a notch similar to notch 1239 formed
in the disc 1236; the friction-dise 1294 is provided with the hub 1295, bored to fit
the shaft 1285, and has formed in the edge thereof a notch similar to notch 1241,
formed in the edge of disc 1240; said disc is also provided with contact-pins
similar to pins 1249 and 1250. The friction-clamps 1299 are provided with the
leather friction-washers 1300, which bear on the hub, 1295, of the friction-disc 1294.
The clamps 1299 are provided with the clamp-screw 1301, nut 1302, and the
spring 1303; said clamps are also provided with the stud 1304 fixed in the
bracket 1286. The operation of this mechanism will be understood without further
explanation, it being the same as that of the envelope stop-motion herein before
described. Any obstruction preventing the full forward movement of the plunger
causes the notches formed in the discs 1293 and 1294 (which are similar to notches 1239
and 1241, but are not shown in the drawings) to be brought into line, so that on the
return stroke the pawl catches in said notches and thus turns shaft 1285 to release the
rod 1261, and thus allow the spring 1266 to stop the machine, as heretofore more
fully pointed out in connection with the envelope-plunger stop-motion.
Figs. 135, 136, 137 and 138 are views illustrating the operation of the machine, by
showing the progress of the pickers in their course from station to station, and the
manner of carrying an envelope-blank through some of the steps of its manufacture
into a complete envelope. The several stations are designated by C1, C2, C³ and C³,
as in the diagrammatic view, Fig. 134. The picker-turret 210 has an intermittent
rotary motion in the direction indicated by the arrow, and turns ninety degrees at
each movement thereof; it carries the four picker-frames 212, each frame carrying a
stem or spindle 213, which spindles each carry a pair of picker-arms 219 and 219
(see also Fig. 24, Sheet 9) that are respectively the seal-picker and the back-picker of
the several pairs of them. When referred to collectively, said pickers are generally
called "pickers 212"; or separately without choice, "picker 219." The pickers are
arranged in pairs, which are set substantially radial to the axis of turret 210. The
picker-faces; or "pickers" proper, are formed of india rubber properly vulcanized.
(See Figs. 21 and 22, Sheet 9.) 406 designates a gum-delivering plate, made to
revolve simultaneously and uniformly with the pickers. 303 designates a pile of
blanks as placed upon the blank-feed-plate 270 (see Fig. 24, Sheet 9). When, in the
operation of the machine, one pair of pickers has taken the required supply of gum
from plate 406, said pickers move one station in the direction indicated by the arrow,
as shown in Fig. 135. The gum on the picker-faces causes the topmost blank of the
pile 303 to adhere thereto; when the first pair of pickers is taking up a blank, the
second is taking gum from plate 406. The pickers again move in the direction
indicated by the arrow, and come to the position shown in Fig. 136; the first pair of
pickers having carried the aforementioned blank to the creasing-station, as shown.
The second pair of pickers is now taking up a blank from pile 303, and the third pair
taking gum from plate 406. In the group of figures now under consideration, 595
designates the creaser-slide carrying the upper creaser-die; the upper portion of said
slide being broken away. The blank carried by the first pair of pickers having been
creased, the pickers move again, always in the direction of the arrow; the first pair
of pickers delivering the blank carried thereby onto the folding-plate 831, the second
pair carrying its blank to the creaser ; while the third pair of pickers is taking up
. another blank, and the fourth pair is taking gun from the gum-plate 406. Each pair
of pickers go in turn to each station, and at the same station each operates in the same
manner.

page_text: The general operation of my improved envelope-machine is as follows: A pile of
blanks. 303. which have been previously cut to the required shape and size, are placed
upon the blank-supporting plate 270 between the guides 260, 200, 261 and 261ª, and
the blank-feeding devices are then set to properly feed up said plate to bring the
uppermost blank to the separators. The gum-box 441 is next supplied with suitable
solution of gum, and the gum-spreading appliances suitably adjusted to properly
spread the gum on the gum-plate 406; and this plate is elevated by means of the
handle 434 and the devices hereinbefore described to bring its upper surface to the
The ink-
proper plane for the descending rearward picker to strike thereon.
fountain 686 is also supplied with ink; the machine being run idle for a few moments,
to properly distribute the ink over the several rollers of the inking apparatus. The
machine now being started by means of one of the handles 92 and 93 and connections
described for that purpose, the picker-turret 210, carrying the picker-arms 219
and 219, is intermittently revolved in the manner and by the means set forth in the
description of the. " picker mechanism." On the first downward movement of the
pickers, (said movement being governed by the picker-cam 240,) one pair of pickers
is lowered onto. the gum-plate 406, receiving a coat of gum therefrom these pickers
are now raised by the said cam 240, and the turret is turned forward one-quarter of a
revolution, thereby carrying the pickers that have just taken gum to a position
immediately above the said pile of blanks 303. One end-flap of the topmost blank of
the said pile of blanks having been gummed by the end-gumming mechanism as
herein before set forth, the return movement of the cam 240 now allows the pickers to
be again lowered, the gummed pair onto the pile of blanks 303, and the second pair
onto the gum-plate 406. This done, the said pickers are immediately lifted by
cam 240, the first-mentioned pair carrying with it a blank from the said pile, which
the gum has caused to adhere thereto; the picker-turret 210 is again turned forward
one-quarter of a revolution, carrying the blank on the first pair of pickers to a position
immediately between the upper and lower creasing-dies. The cam 240 again allowing
the pickers to be lowered, the blank carried by the first pair is lowered onto the upper
side spring-plates, 632, and the upper end spring-plates, 634, of the lower creasing-
die, as shown in Fig. 51. At the same time, the second pair of pickers is lowered
onto the pile of blanks, and the third pair onto the gum-plate 406. The upper
creaser-die 605 is now brought down in the manner and by the means hereinbefore
described, and the aforementioned blank is creased without removing it from the
pickers by which it is carried. While the first-mentioned blank is firmly held between
the upper and lower creasing-dies, the type (having been previously inked by the
inking-roller 788 in the manner herein before fully described, and by means of the
inking-cam. 108 and its connections) is brought up against the said blank by means of
the printing-cam 102 (and the aims and connecting mechanism hereinbefore described
therefor), thus printing the blank, and being immediately withdrawn therefrom.. As
soon as the blank has been printed, the upper creasing-die 605 is raised, and releases.
the blank. The cam 240 now raises again the pickers, and the turret is turned forward
one-quarter of a revolution, carrying the first blank to the folding-station, the second
blank to the creasing-station, the third pair of pickers to the blank-station,, and the
fourth pair of pickers to the gumming-station. Cam 240 now allowing the pickers to
again be lowered the first blank rests on one of the folding-plates 831; the second
blank on the lower creasing-die; the third pair of pickers on the pile of blanks 303;
and the fourth pair of pickers on the gum-plate 406. (See Figs. 135 to 138 inclusive.)
The end-fold wings 836 and 837 are now operated by means of the end-fold .tams 843
and 844, to fold down the end-flaps of the first blank; wing 836 operating a little in
advance of wing 837, so that the outermost flap (which has been previously gummed
as before stated) shall overlap the innermost flap. While this operation is being per-
formed, the second blank is being creased and printed in the manner before described.
The pickers being, again raised as before, and the end-fold wings holding the first
H

page_text: blank firmly to the folding-plate 831, the upward movement of the pickers detaches
the blank from said pickers. The said turret is now revolved one-quarter of a turn in
the direction indicated by the arrows in Figs. 70 to 73 by means of the gearing herein-
before described. (See Fig. 69.) This brings the back-flap of the envelope against
the upper edge of the back-flap folder, and thus partially folds over the said flap. The
back-fold cam 110 now operates, through the arm 858 and its connections, to press
the back-fold wing 856 firmly against the back-flap of the first blank, sticking the
gummed edge of said flap firmly to the end-flaps. (See Figs. 71 and 75.) While the
last-mentioned operation is being performed, the end-flaps of the second blank are
being folded, and a third blank is being creased and printed, all in the manner above
described. The fold-turret is again turned one-quarter of a revolution in the same
direction, and the seal-folder is operated by the seal-fold cam 106 and the connections
described (see Figs. 71 and 73) to turn or fold over the seal-flap of the first blank
on its creased line, without pressing the gummed edge thereof to the back-flap of the
said blank; this being prevented by the edges of the end-fold wings, which are shaped
therefor in a well-known manner. During the performance of the last-mentioned
operation, the back-flap of the second blank is being folded over and closed down; the
end-flaps of the third blank are being folded; and a fourth blank is being creased and
printed. The fold-turret spider now makes another quarter-turn in the direction of
the arrow; this movement having been completed, the seal-flap of the first blank
(which has now been completely folded, and should therefore be designated as an
envelope) is grasped by the upper nipper SS6 and the lower nipper 891 of the transfer
mechanism; at the same time the end-fold cams 843 and 844 operate to raise the end-
fold wings, and release the said envelope from the plate 831 of the fold-turret. The
said transfer mechanism now operates as hereinbefore described to transfer the envelope
that has just been folded from the fold-turret to the transfer-trough 938. (See Figs. 75
to 78 inclusive.) The nippers or fingers 886 and 891 having transferred one envelope
from the folding-turret to the transfer-trough 983, return immediately for a second
envelope; and as this is delivered to the said trough 983, the transfer-fingers 920
and 921 push the first envelope into the endless-carrier or apron 955, said envelope
resting on one of the fingers 956 of said carrier. As hereinbefore described, said
endless carrier is carried on a supporting pulley suspended overhead in a well-known
manner, and is operated by the endless-carrier driving apparatus, to carry the envelopes
up and over said pulley and down on the opposite side thereof; this circuit taking a
sufficient time to allow the gum on said envelopes to thoroughly dry. As the envelopes
are brought one by one by the carrier to the counting apparatus, they are placed by
the placer 986 onto the envelope-way 985, and are there counted as herein before
particularly described. The envelope-plunger 1025 operates to push the envelopes
one by one along said envelope-way into the packing-box; and, as hereinbefore
stated in the detailed description of the said packing-box, when twenty-five envelopes
have been packed in said Lox, the bunch-plunger 1179 is operated to push the said
envelopes out of said packing-box and into the bunch-trough 1575; the band 1476
being placed on the said bunch as it passes through the band-carrier, on which carrier
the band has previously been placed, as explained in the detailed description of the
banding mechanism. Thus the bunches of completed envelopes are banded and
delivered to the bunch-trough forward of the bunch-pusher 1572, which operates as
herein before described to push the said bunches along the said trough between and
past the bunch-hooks or catches 1576 and 1577, to the front of the machine, where
they are taken by the operator and packed into boxes for shipment.
