COMPLETE SPECIFICATION.
Improvements in Machines for Making and Printing Envelopes.
I, CHARLES HENRY HEYWOOD, residing at number Ingraham Avenue, in the
City of Springfield, County of Hampden, and State of Massachusetts, United States
of America, mechanical engineer, do hereby declare the nature of this invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
This invention relates to envelope making and imprinting machinery, the object
thereof being to automatically feed and present envelope-blanks to the action of
gumming and printing mechanism, to thence convey the gummed and printed blanks
to the action of creasing and folding mechanism and to then dry and deliver the
envelopes in clearly defined bunches.
The invention comprises:
Improvements in mechanism controlled by the presence or non-presence of a blank
on the gumming bed and acting in conjunction with the gumming bed actuating
mechanism, whereby in the operation of the machine, in the event of the non-presence
of a blank on the gumming bed, accidental or otherwise, the said bed will then
he carried to and held at a height below the plane of impact thereupon of
the reciprocating gummer;-in conveying devices for moving the blanks from
the gumming bed to the creasing and folding frame, and in adjusting devices
operating in conjunction therewith;-in improvements in the seal-flap folder
mechanisin, and in co-acting devices for peculiarly delivering the envelopes to the
drying-chains-in devices for expelling the envelopes from the chains and in
receiving and bunching mechanism, and in counting mechanism. The invention
further consists in the combination with a gumming bed having an aperture or
recess in and through its body, of a platen above said aperture, a printing bed
adapted to have a reciprocating movement through said aperture, and a reciprocating
gummer, the said gummer and type-bed being arranged for their reciprocatory
movements in lines embraced within the area on said gumming bed to be covered by
the blank to be gummed and printed thereon, whereby a blank resting upon said bed
may be gummed and printed without moving the blank between the one operation
and the other. The invention further consists in minor details of construction as
will hereinafter more fully appear, and be set forth in the claims.
In the accompanying drawings forming part of this specification the mechanism
constituting the present invention is illustrated, and similar characters of reference

The operative parts of the machine are directly or indirectly supported on the end
standards, A, A2, and intermediate standard, B,-suitably braced by cross-girders, ‚‹i;——
and the table, C.
j, represents what is most properly termed the front-side of the machine, k, the
rear-side, 1, the front-end, and "m, the rear-end.
Four shafts are employed herein designated as shafts, 1, 2, 3 and 5, which
run from end to end of the machine, and there is also another shaft, 4, which
extends between the front end and intermediate standards, A, B.
Power is primarily communicated to the machine through the shaft, il, which,
through its spur-gear, n, meshing with the gear, o, of shaft, 2, secures the rotation
of the latter shaft. The gear, o, meshes with the spur-gear, p, on shaft, 3, securing
its rotation, and a spur-gear, n, on said shaft, 3, in an offset plane engages with a
gear, r, of the shaft, 4, with which an idler gear s, neshes and also engages with a
gear, t, on shaft, 5. A driving pulley, 6, is secured on shaft, 1, and on shaft 3, is
fixed a balance wheel, 7.
The gum rolls, 30, mounted in journals of the gun boxes, 32, with their
arbors, 33, 33, ranging horizontally lengthwise of the machine, receive rotary motion
through the cross-shaft, 34, having bevel-gears, 35, 35, meshing with bevel gears on

page_text: said gum-roll arbors, and said cross-shaft receives its rotation by being bevel geared
as at 38, with a vertical shaft, 39, which in turn is mitre-geared as at 40, with the
shaft, 5.
The gummer rollers, 42, 42, move with their boxes on horizontal tracks, 43, across the
lower face of the riciprocating gummers, 44, when raised, and normally rest upon
the gum-rolls as usual, receiving their sliding movements through the connecting
rods; 45, 45, secured to the slide boxes of said rolls, and to the ends of an inter-
mediately pivoted lever, 46, to a radial arm, 47, of which extending from the center
of rotation thereof a connecting rod, 48, is secured which by its other end is fastened
to the end of a lever, 49, swinging from a fixed girder-shaft, 50, between the
standards, and a cam on shaft, 3, not shown but working against an intermediate
part of said lever imparts the required vibratory motion thereto in a manner well
known in envelope machines.
Blanks from which the envelopes are to be formed are held at a proper and sub-
stantially uniform height by the blank-supporting table, M, of the elevator which may
be of any construction as well known in envelope-machines.
The picker, D, which is of the pneumatic class, comprises a series of vertical
tubes, 53, 53, vertically movable through and spring-pressed from horizontally pro-
jecting lugs, 54, of a carrier-plate, 55, which is vertically movable in ways, 56, secured
to the gum-box plate, E, or other suitable fixed part of the machine. Each tube (see
Figure 4) at a slight distance above the place of its passage through the socket, 57,
of the lower lug, 54, has a radially projecting pin, 58, between which and the under
side of the upper lug is placed a spiral spring, 59, the recoil of which serves to
maintain the picker-tubes normally in their lowermost presentation which is limited
and made uniform as to all the pickers by the regularly arranged and laterally extend-
ing abutment pins, 60, of the tubes a slight distance above said upper lug.
That on the downward thrust of the picker against the pile of blanks the tubes may
not be forced upwardly with relation to the socketed lugs to an excessive extent,
a stop-pin, 62, is placed on one or more of the said tubes a short distance below the
lower lug.
Each tube has a continuous passage- through it and is open at its lower end, and to
its upper end a flexible air-conduit, 63, is connected, which extends to a common
chamber, 64, conveniently located on a fixed part of the machine.
The picker is reciprocated by means of a connecting rod, 65, between a radial
arm, 66, on a rocker-shaft, 67, supported in stands from the gum-box plate, and an
ear-piece 69, formed on the supporting plate, 55, of the picker, the said rocker-shaft
being actuated in any desired manner.
The vacuum is produced in the chamber, 64, through the conduit, u, from the suction
pump; F, seen in Figure 2, which is pivotally hung by one end on the machine frame,
the reciprocating motion to the plunger, 70, of which is imparted by the swinging of
a lever, 72; hung on said girder-shaft, 50, and moved by the forked thrust-rod, 73,
receiving its motion in one direction by a cam, 52, on shaft, 3, the return movements
of the parts being under the reaction of a spring, 74.
The blanks,, by their front edge portions are raised by the pneumatic picker,
which is properly located therefor, and are then carried by the action of sliding feed-in
mechanism to the feeding-in tapes. A feed-in mechanism is substantially shown
at F, in Figures 1 and 2, the same being guided and receiving its horizontal and
reciprocating motion through any suitable mechanism such as is commonly used for
imparting to a device a properly timed reciprocatory movement, and as particularly
shown the front horizontal carrier-bar is provided with flat horizontal inwardly
extending slide fingers, 75, 75, located in a plane slightly above the level of the top
of the pile of blanks and provided with abutment lugs, 76, on its upper side.
improved construction of the slide finger, 75, consists in forming the lug, 76, which is
screwed to the said slide finger with an angular extension, 76, which extends across
the edge of the slide finger, and thereby no crevice between the adjoining faces of
the lug and finger is left open into which the edge of, the blank might catch.
An

page_text: .
After the picker has lifted the front edge portion of a blank and the suction thereof
has ceased, such portion drops, but the feed-in slide fingers at such time have been
moved inwardly nearly or quite to the position seen in Figure 1, and, having a slight
further inward movement the blank is fed to enter by its rear edge to the bind and
carrying action of the carrier-tapes, 77-78.
Upper and lower pairs of slide-strips, 79-80, are arranged at each side of the
main middle portion of the blank, extending from the front towards the rear of the
machine, and at their rear ends terminating at or about at the rear side of the gum-
ming bed, which is located at the rear of said feed-in tapes. The lower slide-strip of
each pair has its forward ends just at the rear of the edges of the end flaps of
the blanks being downwardly deflected thereat and are held stationary by any suitable
supporting means.
The upper slide-strips, 79, of both pairs extend by their forward ends over the end
flaps of the blanks, being supported thereat by pending rods, 82, secured to the under
side of the gum-box plate and the one towards the front end, 7, of the machine is
similarly fixed and suspended by its rear end while the upper slide-strip towards the
rear end, m, of the machine is hung on the end of a radial arm, 83, which is loosely
supported on a horizontal shaft, 84, having suitable bearings in bangers from the
gum-box plate; and to a laterally projecting stud, 85, on an intermediate part of said
radial arm, 83, a connecting rod, 88, is secured, its other end being in engagement
with and to receive a reciprocating motion from a cam, 81, on the driving shaft, 5,
and at a certain instant in each operation of the machine said slide-strip will be
raised by its rear end, swinging from its. forward end as a pivotal point.
G, represents a blank supporting bed and in an envelope-machine such as described
is termed the "gumming-bed "which is of a general rectangular form, having an
aperture 89, in its middle portion outside of which it is of a form to serve as a support
for the flaps or extremities of the blanks, the proper location of one thereon being
indicated in dotted lines at a¹, in Figure 1.
Adjusting and abutment lugs, 90, 90, are to be provided on the slide-strips, 79, so
that the blanks may not be carried rearwardly further than desired and necessary to
be in proper position to be gummed or printed or both, and the one on the upper
slide-strip, 79, towards the end, m, of the machine, projecting downwardly and
normally to be across the plane of travel of the envelope blank of course moves
upwardly out of such plane when the slide-strip is upwardly moved as already
explained. It is immaterial on which of the slide-strips the abutment lug, 90,
towards the front end of the machine is located, whether on the upper or lower one,
it being observed that it must always, however, project across the horizontal plane of
travel of the blank.
As seen in Figures 14 and 15, the feed-in tapes, 77, 78, are carried on two sets
of rolls, 92 and 93, upper and lower. The rolls of the upper set are carried in
bearings suspended from the gum-box plate, or other stationary part. The arbor, 94,
of one of the rolls of the upper set is provided with a spur-gear,, 95, and receives its
rotation in the proper direction through a train of gears, indicated at, 96, Figure 2,
from the arbor, 33, of one of the gum-box rolls, to which rotation is imparted
as usual.
The lower set of rolls, 93, for the other tape is journalled in bearings of a stand
resting on the table, C, and its endless tape being in frictional contact with the upper
tape is moved thereby and therewith. The stand for the lower set of tape-rolls is
provided with a slot, 97, having a general direction at an angle to the line of the tape
from the lower edge of the one roll to that of the other, and an adjustable tightener-
roli, 98, is guided and adapted to be fixed at any point in the length of said slot
whereby it may take up any slack in the tape. A similar tightener roll, plainly, may
be employed for the upper set of tapes.
Slide ways, 99, are formed in the under side of the gum-box plate above and
having a direction parallel with the feed of the last described tapes, and a frame, 100,
is movable in said ways carrying a pair of legs, 102, extending obliquely downward

page_text: at each side of the feed-in tapes, and on the lower ends of said legs are pivoted
dogs, 10, adapted to swing from a pivotal point intermediate thereof with their for-
ward ends lowermost.
The said frame, 100, receives its horizontal reciprocatory motion from the
connecting rod, 104, attached thereto and to the radial arm, 105, on a rocker-
shaft, 106, the rocking motion being imparted to said shaft by the engagement
with another radial arm, 107, thereof of a rod, 108, actuated by a cam, 109, on the
shaft, 2.
The gumming-bed, G,is carried by a pair of parallel arms 110, which by their
forward ends are pivoted on stands, 111, near the front of the table, C, from which
they may swing, and said arms at their rear ends behind the gumming-bed are
carried on the lower ends of links, 112, 112, which by their upper ends are
carried by radial arms, 113, 113, of a rocker-shaft, 114, which is also provided with
another radial arm, 115, which receives its back and forth swinging movement
from its connection with a thrust rod, 116, operated from a cam, 117, on shaft 5, see
Figure 6.
'
A peculiar latching form of connection between the thrust rod, 116, and the radial
arm, 115, will be hereafter described in connection with the mechanism for securing a
non-gumming effect on the absence of a blank on the gumming-bed when the same is
carried upwardly.
The printing bed, H, is movable in vertical slide ways 118, in the standards, A, B,
below the table and at its upper side carries the form and type for printing through
the aperture of the gumming-bed upon the middle portion of the blank, and against
a fixed platen, P, supported under the arch-frame of the machine.
A pair of toggles, g, g, operated by cams, 120, on the shaft 2, gives the rising and
falling motion to the type bed. Each of the duplicated toggle devices consists of the
stirrup, 122, pivotally connected at 123, to the type-bed, and receiving a tension
rod, 124, having a screw-thread and set-nut engagement therewith, and a triangular
lever, 12, which by one end of its hypothenuse line is pivoted to the lower end of
the said rod, 124, is fulcrumed at its apex as at, h, and at its other point is provided
with a roller, 126, against which the said cam, 120, operates, to straighten the toggle,
a suitable spring, 127, causing the doubling of the levers for lowering the bed at the
proper period.
The gummers, 44, are carried on two rods, 130, 130, playing through bearing
guides, 132, of a fixed standard, 133, supported from the arch, J, above the gumming-
bed, united by a tie-beam, 134, on the side and at the center of which, a roller, 131,
is journalled. The gummer rods are moved upwardly by the bearing of the upper
side of the end portion of a radial swinging arm, 135, against said roller, said radial
arm being carried on a rocker-shaft, 136, supported in stands on the arch, J, and
having another radial arm, 138, to which one end of a connecting rod, 137, is
secured, its other being connected to the end of a lever, 139, swinging from the
girder-shaft, 50, said lever receiving its upward movement from a cam on shaft, 3, as
seen in Figure 22.
The gunimers, raised in the manner described, are permitted to fall for their
gumming action by their own weight with and on the radial lever arm, 135, the limit
of the downward movement of said arm being made to correspond approximately to
the required downward throw of the gummers.
Upon the standard, 133, above the pintle, 142, for the roller, 131, which is projected
laterally, is a short rocker-shaft 143, having thereon a radially projecting hooked
arm, 144, a lapted to be swung into and out of a position of engagement with said
roll-pintle, 132. To a radial arm, 145, on said rocker-shaft, 143, one end of a
connecting rod, 146, is fastened, which is curved by its other end to encircle the
shaft, 67, on the stand at the front of the machine and pivotally engages by its end
with the loose collar, 147, on said shaft, as seen in Figure 2, and in detail in
Figure 20. A curved arm. 148, is also pivoted to said collar to which a spring, 151,
by its one end is attached, being by its other end secured to a stationary part of the
machine. The turning of the collar by the radial handle, 149, or otherwise, in one

page_text: direction, places the hook into position for engagement with the pintle, 131, the
reverse movement of the collar placing the collar out of engagement therewith, and
thereby the gummers may be supported in an elevated position and without any
interference with the running of the machine, it being understood that the said
spring, 151, will act to maintain the parts in whichever positive position they may be
placed, whether for the hook to be in or out of engagement with the pintle carried on
the plunger tie-beam, according as the point of the pivotal engagement of said curved
arm, 148, is at either side of the line of spring strain.
150 represents a reciprocating bridging slide about on a level with the slide-
strips, 80, for being projected into a position over the rear part of the gumming bed
when in its lowermost position, for supporting the rear flap when fed forward to its
position to be gummed and printed, the said slide being withdrawn just before the
gumming-bed is carried into its uppermost position. The said slide plays through
ways of a hanger, 152, its upper surface being provided with rack-teeth with which
a spur-gear, 153, meshes which is carried on a rock-shaft, 84, which has bearings in
said hanger and is further supported on another hanger, 154.
The said rock-shaft is provided at a suitable portion of its length with a
pinion, 155, and supports a guiding shoe K, through which a rack, 156, reciprocates
and is held thereby in engagement with the pinion, said rack being actuated by the
cam, 157, on shaft, 5.
The form of guiding shoe, K, above mentioned is shown more in detail in connec-
tion with the mechanism employed for operating the reciprocating folder-plunger,
Figures 11 12 and 13, in which is also employed, and consists of a back-plate, 158,
provided with right-angled ear-pieces 159, 159, having perforations, 160, for bearings,
loosely sui rounding the shaft and between which ear-pieces the fixed pinion of the
shaft is disposed. The rack playing through the said shoe behind the pinion, being
guided by the back wall and insides of the ear-pieces, by its rack-teeth on its front
side engages the pinion. The shoe being loosely supported on the shaft may swing
thereon to correspond to the swinging motion of the cam actuated rod, which motion
is imparted thereto by the lateral throw of the cam.
The mechanism for ensuring the rising of the gumming-bed a less distance than
usual in the event of the non-presence of a blank on said gumming-bed at the time of
its being carried upwardly consists in the combination of parts, and operates, as
follows:-
170 respresents a horizontal rocker-shaft supported on a stand 171, of the table C,
and carries a radially extending fixed arm, 172, having a downwardly extending
foot, 173, which stands over an aperture 174, in the portion of the gumming-bed for
supporting one end flap of the blank so that when the gumming-bed rises with a blank
thereon the said foot will, by said blank, be raised and the shaft 170, rocked. There
is on said shaft 170, an upwardly entending radial arm, 175, having near its upper
end a lateral shoulder or abutment extension, 176.
The cam-operated and vertically reciprocated thrust-rod, 116, is provided with an
angular pawl, f, one arm, 177, of which is hooked and the other, 178, thereof extends
into proximity to the abutment shoulder, 176, on the arm, 175, and is provided with
- a laterally extending pin, 179, which projects to intersect the line of the said shoulder
when the same is in the position seen in Figure 6, such position being only ensured,
however, by the non-presence of a blank over the gumming-bed.
Therefore so assuming the absence of a blank from the gumming bed and the
relation of the parts as shown in Figure 6, on the then continued upward throw of
the thrust rod, 116, the pawl will be swung on its pivot, 180, owing to the contact
of the pin, 179, against the shoulder, 176, as explained, and the hooked arm, 177,
will be swung out of engagement with the laterally projecting stud, 182, on the radial
arm, 115, and just before the gummers descend to their limit of downward movement
said radial arm will fall back or swing downwardly, its pin, 182, moving down
through the slot, 183, of the thrust-rod until the abutment-pin, 114, on the rock-
shaft, 114, comes to a bearing on the stop, 114, of the bearing support (see
Figure 8) and the radial arms, 113, 113, on said rock-shaft which carry the

page_text: gumming-bed through the link connection will also fall downwardly and the thrust-
rod finishing its upward movement will not operate to carry the gumming bed
upwardly so that it would be in position to receive the impact of the gummers.
The thrust-rod next moving downwardly, the pin, 182, with the arm, 115, being
in its lowermost position (as determined by the abutment-pin and rest for affecting
the roll of the rock-shaft, 114, (shown in Figure 8) the pawl, f, swings back to its
normal position, and it will here be noted that the thrust-rod has such an extent of
downward throw as to carry the pawl-hook below the position of the pin, 182, and
before said thrust-rod again moves upwardly the hooked arm of the pawl carried
thereon will snap into engagement with said pin, 182, and then on an upward throw
of the said thrust-rod and with a blank over the gumming-bed covering the said
aperture, 174, the rock-shaft, 170, will be swung so that the abutment shoulder, 176,
on arm, 175, will be carried across and beyond the vertical line of travel of the
pawl pin, 179, and then, of course, said pawl will not be swung, its hook support
for the radial arm pin, 182, remaining intact and a full upward throw of said arm
with the thrust-rod is secured, a full extent of upward throw of the gumming-bed
being also, obviously, effected. The angular pawl, f, is to be provided with
a spring, 181, or properly weighted, whereby it is caused to retain its normal
operative position.
The mechanism for securing a controlling of the upward movement of the printing.
bed, H, by the non-presence of an envolope-blank on the gumming-bed depends on
securing a lowering of the fulcrum-point, ½, for the triangular members, 125, 125, of
the toggle mechanism.
The said fulcrum-points, h. for the triangular toggle members, 125, are formed by
the cranked portions of a horizontal crank-shaft, I, mounted in fixed supports of the
machine frame extending between the standards, A and B, and also projecting
through the one, B, receiving at its extension a disk, 185, the same being keyed
thereon. The crank-shaft is normally set to present its cranked portions about
vertically over its axis, as indicated. The shifter disk has a nose, 186, for abutment
against a stop-lug, 187, on the frame for limiting its swing when carried into its said
normal position, and, is also provided with another abutment nose, 188, for permitting
the engagement and rest thereon of a vertically disposed locking lever, 189, pivotally
hung on the frame, a spring, 190, tending to keep said lever in its position of
engagement as shown. The said disk, 185, has a notch, 192, formed in its upper
edge and its periphery is rebated as at 193, between said notch, 192, and its abutment
nose, 186, so that the said disk may be partially rotated in the direction of the
arrow, 194, Figure 9.
a
N represents a shifter provided with a hub, 195, loosely surrounding the crank-
shaft outside of the crank-shaft disk having radially extending arm, 196, with an
extension, 197, off-set to lie across the vertical plane of said disk and having therein
a radial socket 198, in which is disposed a slide-dog, 199, held therein by a strap, 200,
said dog being provided with a laterally extending pin, 202, the outward movement
of which on and with said dog, 199, is limited by the end of a short slot, 203, in said
strap (see Figure 26).
A regular parti-rotatable reciprocatory movement is secured to said shafter N, by
means of the pivotal engagement with the radially extending arm, 204, thereof, of
the end of one member, 205, of a toggle, v, the other member, 206, thereof being
pivotally hung as at 207, on a stud of the machine-frame, the distending action being
imparted to said toggle by a cam, 208, on shaft, 2, working against the intermediate
pivotally connected part of the toggle, a spring suitably secured to the toggle
causing the doubling up thereof when permitted so to do under the rotation of
the cam.
w represents a spider lever having three substantially radial arms, 210, 213 and 215,
said spider being intermediately pivoted on a boss of the frame B, as at 211.
One leg, 210, of said spider-lever is properly formed and normally located in the
path of a tappet-cam, 212, on shaft. 3, to receive at each revolution thereof a rearward
movement therefrom, swinging its arm, 213, which has a notch, 214, in its end,

page_text: downwardly, and its upwardly projecting arm, 21ª, swings forward so that its end
may be engaged by the hook, 216, of a catch-lever, 217, located in the
vertical plane of said arm, 215, and carried on a horizontal shaft 217", which is
adapted to roll or oscillate and for its support may be extended from the standard A,
to, through and beyond the standard B, and said shaft, 217ª, also has another radially
extending lever, 217", affixed thereto which is, however, in a plane coincident with or
adjacent to that of a "gravity-bar, 228" to be soon hereinafter mentioned, and which
gravity-bar as at present arranged is in the same vertical plane as the arm, 172, and
the gum-bed aperture, 174, hereinhefore referred to.
The forwardly extending arm, 213, is also provided with an upwardly extending
stud, 218.
The lever, 189, has a rearwardly extending arm carrying in an offset plane a
pivoted dog, 220, having a spring, 219, applied between it and said arm, 189, for
maintaining said dog normally depressed, said dog being provided with a stop lug, 222,
for limiting its downward swing.
.
225 represents a horizontally disposed thrust-rod operated from a cam 221, on
shaft 2, in one direction and under the recoil of a spring in the other across the line
of said dog, 220, when in its depressed position.
228 represents a gravity-bar capable of a vertical movement within certain limits
and guided by any suitable means upon the frame of the machine. Said gravity-bar
is hooked at its upper end as at 229, and is provided towards its lower end with a
lateral stud 230, to abut against the forward arm of the intermediately pivoted
catch, 217, when said bar is permitted to drop.
A downwardly extending radial arm, 232, is fixed on the rocker-shaft, 170, which
is oscillated as heretofore explained, said radial arm being hooked at its lower end as
at 233.
On the shaft 5, (see Figure 6) is a snail cam, 234, which operates upon one arm, 235,
of an angular lever, O, its other arm, 236, extending forwardly for an engagement
with a pin, 237, on said gravity-bar.
Under the usual running of the machine, and envelope-blanks being regularly fed
on to the gumming-bed, at each reciprocating of the parts the shifter is swing through
a quarter of a circle, the pin, 202, of its dog, 199, being carried into the notch, 214,
of the spider-arm, 213, and then said pin by the movement of said spider is quickly
carried downwardly and the dog is moved with it into and then out of the notch, 192,
in the crank-shaft disk. The spider-lever is permitted to be moved by its spring to
carry the dog out of the said notch by the disengagement of its arm, 215, with the
catch-hook, 216, the same being accomplished by the dropping of the gravity-bar,
when the snail cam under its rotation permits the arm to suddenly swing inward, its
arm swinging downward, out of support for the gravity-bar, and no effect is had by
the shifter to move the crank shaft disk and crank-shaft.
By the non-presence, however, of an envelope blank on the gumming-bed, the
shaft, 170, is not oscillated, and at the time it would otherwise be permitted to drop,
by the operation of the lever, 0, and snail cam mechanism, it, the gravity-bar, is
prevented from so dropping, being caught or held by the hooked arm, 232, and after
the dog has been carried down into the notch of the crank-shaft disk it is not lifted
out thereof by the arm, 213, for the same is engaged by the catch, 216, and not
permitted to make the return swing with its spring, and the dog, 199, is not upwardly
moved out of the notch, 192; and then, on the rearward movement of the thrust-
rod, 225, it abuts by its nose against the pivoted dog, 220, forcing the arm, 189,
rearwardly so that its lower end passes out of engagement with the nose, 188, of the
crank-shaft disk freeing the same for rotation when, on the doubling up of the
toggle, v, carrying the shifter arm, 196, downward and forward, the shifter disk is
partially rotated therewith, and the center line of the cranked portions of the shaft is
carried downwardly so that the distance between the fulcrum point of said toggle and
the face of the platen is increased, and whereby, on the upward projection of the
printing-bed thereby, it will be carried only to within a short distance of the plane of
printing.

page_text: A rib 240, of quadrant form is cast on or secured to the frame, B, as indicated in
dotted lines in Figure 9, and in plan, Figure 10, said rib serving to maintain the
dog, 199, through its pin, 202, from any end wise movement on the shifter arm, 196,
in its traverse so that when the dog is raised out of the notch, 192, in the regular
and proper running of the machine, the pin will be made to traverse on the upper side
of the rib, but when the dog is not lifted out of the notch, owing to the failure of the
gravity-bar to drop, the pin will traverse on the under side of said rib and will
continue so to do for as many times as the machine reciprocates and the gravity-bar
is held from dropping, and of course, under such a disposition of the parts the crank-
shaft will be partially rotated at each reciprocation of the machine to afford the
lowered fuleruin from which the printing-bed toggle mechanism is operated.
By the automatic controlling of the gumming-bed and of the printing-bed as
described, plainly, when no envelope-blank is on the gumming-bed, the said bed will
not be covered with gum from the gummers, nor will the platen be covered with ink
from the type on the printing-bed.
After the envelope-blanks have been gummed and printed they are conveyed from
the gumming-bed to the creasing-frame in a direction at right angles to the line of
feed to the gumming-bed.
As indicated by dotted lines in the plan view Figure 1, the envelope-blank by
its end-flap towards the folder mechanism projects beyond the edge of the gumming-
bed slightly, which may be recessed as shown at 250), and above said projecting
end of the blank is a roller, 252, around which and one or more other rollers, 253,
suitably supported in hangers, 254, from the arch J, is an endless carrier tape, 255.
Below the carrier tape is another carrier tape 256, having a portion of its length in
contact with a portion of the length of the upper tape, and another portion of its
length towards the gumming-bed is adapted to be carried into and out of contact
with the tape thereabove.
257 represents a roll for driving and partially supporting the tape, receiving its
rotary motion by its shaft through any suitable means, the tape thence passes onto
the under periphery of the two rolls, 258, 259, and partly around the latter, and
thence rearward over and beyond the periphery of the roll, 258, to above the
periphery of said driving roll, to and partially around another roll, 260, thence
around one or more tightener rolls, 262, to the point therein at which the above
description was commenced.
The roll 259, is carried on the radial arm, 263, of an oscillating hub, 264, loosely
supported on a horizontal arbor, 266, and receiving its rocking motion through the
other radial arm, 265, thereof, the same being fastened to one end of a connecting
rod, 267, receiving its rotation from a cam in the same manner as described and
shown for many of the other connecting rods employed in this machine. The said
arbor forms the support and bearing for the roll, 258. At the time of gumming and
printing the blank the roll is carried downwardly, but after the blank has been
gummed and printed and the mechanisms for performing such functions have been
withdrawn, the roll, 259, is swung upwardly with the tape, 256, thereon to bind the
blank between it and the upper tape, when the blank will be, by said moving tapes,
fed forward over the creasing box under the plunger-block, 268.
269, 269, represents a pair of blank-adjusting arms swinging on and radially from,
a rock-shaft, 270, to the one end of another radial arm, 272, of which a connecting
rod, 273, is secured, its other end being secured to a radial arm, 274, on another rock-
shaft, 275, receiving its roll from a rod, 271, connected to a radial arm, 271º, thereof
and engaging a cam, 271b, on the shaft 5. The said arms are swung upwardly forward
at the time of the feed of a blank from the gumming-bed and after such blank has
been carried out from between said tapes, 255, 256, onto the creasing-frame, I', said
arms swing against the edge of said blank and move slightly forward to the
adjusting abutment guages, 276, 276, the blank being then in position to be forced
downwardly through the rectangular opening in said frame by the creasing plunger,
on to the folding-bed, Q, to be then acted on by the flap folder wings.
The novel mechanism for operating the folder-plunger will be now described, and
B

page_text: consists in providing a rack bar, 278 on the rear edge of the folder plunger-shaft, 279,
and providing to mesh therewith a spur-gear, 280, which is carried on a horizontal
shaft, 281, journalled in boxes of the arch. The said shaft carries a pinion, 282, at
another portion of its length, and through a loosely journalled shoe, K, of the
construction already described and supported on said shaft plays a racked reciprocating
rod, 283, the upward movement of which is imparted thereto in one direction
by, a cam, 284, on the shaft, a spring, 285, securing the return movement of the said
rod.
The blank having been forced on to the solid folding-bed Q, with its flaps creased as
usual, the flaps thereof are then folded down by end-flap folder-wings, 286, 286,
operated by ordinary rack and pinion mechanism which are not herein claimed to be
particularly novel, and are therefor not described and by a rear flap folder-wing, 287,
of ordinary construction, and by a front flap-folder, 288, which possesses many features
of novelty.
The practically solid folder-bed which is immovable and fastened to and partially
filling a recess, 289, in the table, C, serves the same purpose as the usual hinged and
downwardly swinging trap-door, the envelopes being delivered to the drier chains
below the table, C, in a peculiar manner, as will shortly appear.
290, represents a frame pivotally supported intermediate thereof by which it may be
rocked, its forward end, 292, serving as an abutment to limit the swing of said frame
in one direction when brought in contact with the under side of the table C, the face of
the platform, 293, carried by its other end being then about flush with the top of the
table and extending through the open recessed part of the said table at the front of the
A block having ear-pieces, 294, to which the front flap-folder is pivoted
as at 295, is supported on and moves as one with said platform.
folder-bed.
The said frame, 290, receives its swinging motion by being provided with a fixed
arm, 296, extending radially from its center of oscillation to which a connecting rod 297,
by one end is secured its other being fastened to one end of a lever, 298, which lever
by its other end if hung for a swing on the girder-shaft, 299, supporting one end of
the drier chain, 300, and a cam, 301, on shaft, 3, works against the intermediate
portion of said lever imparting the swinging notion thereto in the same manner already
described for other similar movable connections.
The front flap-folder receives its opening and closing swinging movement through
the connecting rod, 302, intermediately pivoted swinging arm, 303, and thrust-rod, 30-1,
operated from the cam, 305, on shaft, 5.
After the creased blank has been forced upon the folding-bed and having been
operated upon by the folders, the parts shown in Figure 16, being indicated as in the
positions they are made to occupy at this stage of the operation, the folder flaps are
then swung up and the frame, 290), is then swung carrying the front-folder upward
and forward and leaving the recess, 289, directly in front of the folding bed
unobstructed. The folded envelope is then forced forwardly and downwardly into the
chain, being guided by a chute formed by vertical side walls, 306, 306, and an inclined
rear wall, 307.
The devices for so discharging the envelope from the folder-bed consist of a pair of
curved finger-levers, z, z, intermediately carried by a rock-shaft, 308, under the said
bed. Each finger to be described with relation to its position of inaction, is curved
rearwardly and upwardly to about the level of the top of the folder-bed, and thence is
continued rearwardly in a horizontal extension, 309, to or beyond the rear edge of
said bed, and then terminates in an upwardly and forwardly extending hook, 10.
The finger-carrying rock-shaft, 308, is provided with a radial arm, 11, to which a
cam-operated thrust-rod is connected as indicated in Figure 16, and in the operation
of the said mechanism the fingers force and carry the envelope forward and upward by
its rear end, its forward end moving down the chute, and the fingers, before being
returned to their positions illustrated, follow up the envelope until it stands nearly
vertical, or is in line with and upon the rear plate, 307, of the said chute to be
guided to the chains, the same having certain of its members distended as usual.
The folding-bed is slotted vertically as at, 311, to accommodate the said fingers, and

page_text: the block to which the rear flap-folder is pivoted is to be cut away that the rear
hooked ends of said fingers may be disposed within and across portions of its length.
The endless drier-chain, 300, supported at its forward end as usual and receiving its
intermittent feed movement through ratchet and pallet devices, 312, operated by a
cam-actuated rod, 313, is also at its rear end supported and guided on a pulley, 314,
in substantially the usual manner, but said pulley is eccentrically mounted on its
supporting girder-shaft, 299, so that the distance between the axis of said pulley and
the usual sprocket, supporting and driving the forward end of the chain, may be
varied. 315, represents a sleeve eccentrically bored fitting over the said girder-shaft,
having an extension beyond the side frame, 316, of the chain and there provided with
a handle for turning it, and a set-screw for securing it when properly disposed on said
shaft. The hub of the pulley loosely fits over said sleeve, and by properly turning the
said sleeve, any slack in the chain may be taken up. The envelopes are carried by
the chain around the said pulley and returned to where the position of an envelope
therein is indicated by the dotted line at 318, and the envelope is then expelled from
the chain into a frame like mechanism, T, from which it is then carried to the
receiving box, V.
The blank is forced out of the chain by a splined pusher shaft, 320, having at its
end an arm, 321, provided with a U-shaped socket, 322, therein which is adapted to
overlie the rear upper corner of an envelope and the corner thereof diagonally opposite
thereto (see Figures 18 and 19) is supported on a short narrow horizontal plate, 345,
being carried thereto by the chain, and the so forced envelope is moved from the
position shown in dotted lines at, 323, Figure 18, into a position indicated by the
dotted lines at 324, in the same Figure, and also in Figure 19, within the upper
portion of the said frame.
The endwise motion is imparted to the pusher-shaft, 320, by the link, 325,
Figure 18, connected thereto and to the upper end of a radial arm, 326, swinging on a
rocker-shaft, 327, supported in brackets from the frame, A³. A radial arm, 328, is
formed on or secured to the said rocker-shaft, 327, and to the same is fastened one
end of a connecting rod, 329, (indicated in Figure 16) its other end being attached
to a lever, 330, swinging from the girder-shaft, 299, and receiving its swinging
motion by a cam, 332, on shaft, 3, working against an intermediate portion thereof.
The frame, T, in addition to the narrow short lower horizontal plate, 345, before
mentioned as on a plane with the lower edge of an envelope in the chain to be
next discharged, comprises also an upper parallel plate, 346, of about the length
of the envelope, a little above the upper edge of the envelope to be discharged
from the chain, and over the envelope when it is in its position indicated by
the dotted lines, 324. The said frame also comprises a rear wall plate, 852,
ranging in a plane more or less nearly parallel to and behind the discharged envelope
and also a front. plate, 350, nearly parallel thereto.
The said plates, 345, 346, 350 and 352, are supported or suspended from a
casting, 353, secured on the frame B, and 354, 355, represent vertical shifter-blades
carried by a horizontally sliding sleeve, 56, which is guided and supported on a
long stud or rod, 357, rigidly fixed to the supporting casting on the frame, B.
The means employed for moving said shifter-sleeve will be hereinafter set forth
in connection with the counting mechanism of which said sleeve and its blades
form an essential part.
The shifter-blade, 355, furthest from the chain extends nearly to the upper plate and
also below same for about as great a distance, while the shifter-blade, 354, nearer the
chain has no upward extension beyond its carrying sleeve but has a downward
extension similar to that of its opposing blade, and said blade, 354, is cut away as
at 358, so that it will offer no obstruction to the entrance of an envelope within
the said frame.
W represents a horizontally reciprocating pusher movable in the direction of the
length of the receiving box being located, at the time of the entrance of an envelope
into the frame T, from the chain under the forward portion of said frame,-it being
indicated in Figure 19, as withdrawn from such a position, and it is provided at its

page_text: .
top and in a plane at or slightly below the short and narrow plate, 345, with a
rearwardly extending envelope-supporting bar, 336, onto which the envelope is pushed
and by which it is supported momentarily when fully entered into said frame and
beyond the short ledge or plate, 345, to await the operation of the parts of the
counting mechanism
359 represents a reciprocating curved feeler-finger carried on a horizontal rock-
shaft, 360, bearing in the casting 353, receiving its rocking motion through a con-
necting rod, 362, engaging its radial arm, 361, and extending to the counter below
the receiving box, and said feeler-finger plays rearwardly against an envelope when
resting on the supporting bar, 336, of the pusher, and alongside the plate, 352, or,
when there is no envelope in said frame after a reciprocation of the machine the end
of the feeler-finger enters an aperture, 363, through the wall, 352.
364 represents a ratchet wheel loosely mounted on a stud, 365, of the casting, 353,
and having a number of teeth corresponding to that desired for a bunch of envelopes,
say twenty-five, and from a cam, 366, on shaft, 3, to work against the outer end of
an arm, 367, carrying a spring-pallet. 368, and swinging from said stud, the return of
said arm being under the action of the spring, 369, said ratchet is moved around to
the extent of a tooth at each operation of the machine, except as hereinafter provided.
On the upper end of said arm, 367, above its pivotal point is an extension, 370,
provided in its side with a notch, 372. 373 represents a horizontal rocker-shaft
having a hearing through the lower part of the casting, 353, and at its end furthest
from the chain it is provided with a radial arm, 374, with which said connecting
rod, 362, attached to the radial arm for the feeler is connected. The said rocker-
shaft at its forward end is provided with a radial arm, 375, hooked at its forward end,
and adapted at the time of the non-presence of an envelope in the frame, T, to be
depressed to engage the notch on the arm projection, 370, and prevent the arm, 367,
from following its cam, 366, under the action of its spring, and so draw the pallet
back far enough as to take a new tooth of the ratchet.
377 represents an arm also loosely swinging from the said stud, and operated
by a cam, 378, on the shaft, 3, and a refracting spring, 379, to give the positive
rising and falling and swing motions to the radial arms and rock-shaft, 373, for
operating the said feeler through the connecting rod, 380, engaged with said arm, 377,
and said hooked radial arm, 375.
The engagement of the said connecting rod, 380, with the swinging arm, 375, is
by a pin, 381, on the arm passing through a slot, 382, in the said rod, the latter
being normally supported with the top of its slot resting upon the said pin, and all
so that on the rotation of the cam, 378, to permit the downward swing of the
arm 377, an envelope being in the frame, T, and the finger, 359, not being permitted
to have its full rearward swing owing to its abutment against the said envelope, the
said radial arm will not be depressed to permit its hook to take into the notch, 372,
of the extension of the pallet-carrying-arm and yet the full downward movement of
the arm will be permitted its pin passing downwardly through the slot, 382, of the
connecting rod, 880.
The tendency for a downward swing or movement of the parts, viz. :-the radial
arm, 361, radial arms, 374 and 375, and the connecting rod, 380, ensures the return
movement of such parts after they have been moved in one direction positively by
the cam, 378, and it is this weight which the envelope sustains when in the frame, T,
to prevent the full downward movements of said parts, (the greater portion of said
movement being, however, always permitted in any event) and to permit consequently
the taking of a tooth by the pallet, 368.
384 represents an abutment dog on the front side of the ratchet-wheel which in
each complete rotation of the same passes against and raises the depressed radial
arm, 385, of a rock-shaft, 386, bearing in and through the casting, 353, said rock-
shaft being provided with another radial arm, 387, engaging one arm, 388, of an
angular lever which by its other arm, 389, is secured to a fixed projection of the
shifter-blade sleeve, and at the time of the passage of said abutment dog past the
said radial arm the shifter-blades will be moved laterally.

page_text: The pusher slide, W, receives its reciprocatory movement through the connection
therewith of a thrust-rod, 390, operated in the one direction by a cam, 392, on
shaft, 5, and in the other by the retracting spring, 393, see Figure 23.
The envelope expelled from the chain by the pusher, 321, guided at top and bottom
by the upper plate, 346, and short narrow lower plate, 345, and held against undue
movement across the plane of its face by the front and rear plates 350, 352, on
passing to the position indicated by the dotted lines, Figure 18, its rear lower corner
passing from the short plate, 345, rests by its lower edge on the supporting-bar, 336,
of the pusher, which at such time is forwardly presented.
By the abutment and impediment of the feeler-finger against the envelope, the
mechanism controlled by said feeler as described, is permitted to operate and the
ratchet is moved to the extent of one tooth. The pusher then receding from its
position of support for the envelope in the frame T, the envelope falls at the rear of
the
open end of the receiving box V, such position being indicated by the dotted lines
in Figures 18 and 19. The said pusher W, then moving forward the envelope is
forced into the receiving box, V, being when therein placed, retained, or otherwise
disposed of in any usual or approved manner.
The counter ratchet-wheel once at each revolution thereof by its abutment dog, 384,
through the intervening mechanism, causes, after the envelope has dropped from the
frame to the level of the receiving box bottom, and before the envelope is pushed
into the said receiving box, a slight lateral moving of said shifter-blades, the envelope
being slightly moved therewith in the direction of its length, with its end out of
alignment with the edges of the preceding twenty-four envelopes, is then pushed into
the receiving box, and the number of envelopes to constitute bunches are accurately
and clearly indicated.
As soon as the abutment, 384, has passed out of a position of contact, the time
of which contact is less than the duration of one operation of the machine, the
shifter-blades are returned to their normal positions under the action of the
spring, 396.

tion and in what manner the same is to be performed, I declare that what I
claim is :-
