Improvements in Machines for the Manufacture of Paper Boxes.
1, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
The invention has for its object to produce a rapidly operating machine for the
manufacture of paper boxes and their covers, which machine shall be adjustable
within very wide limits, and shall act with equal facility upon the stock, whether
the latter be heavy or light, and produce the finished article accurately and quickly.
In a machine embodying the present invention the blanks from which the boxes
or covers are to be made are placed in position between guides that are located
above a tank containing wetting devices and pasting devices, the undermost blank
of the pile of blanks being supported between its ends on suitable tracks. The
wetting devices rise at the proper time and wet the said undermost blank trans-
versely and longitudinally along the lines on which subsequently it is to be folded
to form the flanges or sides and ends of the box or cover, the width of the said
flanges depending on the depth of the box or cover to be made, while simultaneously
therewith the pasting devices also rise and apply paste to the parts of the blank
which are to be turned over, in order that other parts of the flanges may be pasted
to them. The blanks are thereafter fed forward by a feeder, one by one, from the
bottom of the pile along supporting tracks into position between a former and a
follower, both of these latter being movable vertically with relation to said tracks
or to the bed of the machine, the wetted and pasted blank being carried up by the
former and the follower and caught and held between, and while it is thus held the
projecting portions of the blank are subjected to the action of side and lip turners,
which latter turn positively the side and corner flaps of the blank over the former,
after which the former rises further with the blank, still taking with it the follower
and moving the blank held between them past side and end wiper-plates, which
cause the end flaps of the blank to be wiped or turned down upon the corner flaps
or lips, said corner flaps or lips previously having been turned over against the
former by the side and lip turners. The side and lip turners are connected and
move together. The flanges or edges of the blank which are to constitute the sides
of the box or cover are turned down first by the side turners, after which the
continued movement of the lip turners folds the said lip turners around the corners
of the former and turns the corner flaps or lips of the blank snugly about the corners
of the former. The side and lip turners remain stationary in such position and hold
the side and corner flaps against the sides and ends of the former until further
vertical movement of the said former causes the end flanges or flaps of the blank to
be turned over the corner flaps. When the end flanges or flaps have been turned
down thus against the corner flaps, the former has reached the limit of upward
movement and it is arrested. The blank is then subjected to compression to
complete the sides and ends of the box or cover, after which the said former, the
follower, and the side and lip turners return to their normal position, and an ejector

page_text: delivers the completed, box or cover from between the separated former and
follower.
The main or driving shaft of the machine has loosely mounted thereon a belt
pulley forming one part of a friction clutch. The friction clutch may be of any
usual or well known, construction having an engaging portion for co-acting with
said belt pulley, said engaging portion being rotatable with the said shaft and
operated by a cone of usual character, the said cone being actuated by suitable
Connections, as for instance, by means of a yoke on a rock-shaft that is operated
through the medium of a band-lever in operative connection with the said rock-
shaft. In order that the machine may be stopped very quickly at times, a brake
wheel is secured to the driving shaft and adapted to be engaged by a friction-shoe
that is secured to a carrier pivoted to the base of the machine and having pivotally
secured thereto an internally threaded collar, said collar engaging with one end of
a rod which at its other end enters a threaded sleeve pivoted to a stud, the two ends
of the said rod being oppositely threaded for engagement with said collar and sleeve.
The rod has thereon between its ends a toothed gear that is in engagement with
the teeth of a rack-bar which is connected by a rod to an arm of the rock-shaft
aforesaid. When the hand-lever aforesaid is moved to one side the clutch will be
moved into engagement with the belt pulley to render the same fast on the main or
driving shaft; the movement of the rock-shaft also moves.the rock-bar in a manner
to rotate the threaded rod and draw the brake-shoe away from the brake-wheel.
When the machine is running, and it is desired to stop it, the hand-lever is moved
in the opposite direction, thereby bringing the clutch out of engagement with the
loose pulley and moving the rack bar in a manner to rotate the threaded rod in the
direction which causes the brake shoe to be formed firmly against the brake-wheel..
A guard-shoe pivotally supported at the opposite side of the brake wheel prevents
the main shaft from being deflected by the pressure of the brake shoe. The
application of the brake occurs simultaneously with the disengagement of the
clutch.
A cam on the cam-shaft of the machine actuates a link connected with an upright
pivoted arm which preferably is formed as a trussed structure. A sliding frame is
connected with the said trussed arm by means of a link, and the feeder, which has
formed therein longitudinal slots, is held to the reciprocating frame by bolts paššing
through such slots, the latter enabling the position of the forward end of the feeder
to be adjusted to the width of the blauk to be acted upon, such adjustment being
necessary in order to adapt the machine to various widths of blanks inasmuch as the
throw of the frame is constant. The feeder is slotted at midwidth to enable it to
pass the middle track hereinafter described, the said track extending to within a
short distance of the former, also hereinafter described.
Side tracks that are parallel to the middle track above referred to are located at
opposite sides of the said middle track, said side tracks being secured to the upper
portions of the paste pans, at the inner sides of the latter, and serving to support
the blank between the points where the latter is wet and where it is pasted, or just
outside the line on which the blank will be folded to constitute the ends of the box or
cover.
The guides between which the pile of blanks is placed preferably are formed as
plates, having at their opposite ends internally threaded bearings which receive
right and left screw-threaded adjusting rods. The said rods are geared to a
connecting shaft which has one end thereof shaped to receive a crank arm whereby
it may be rotated, the rotation thereof causing the opposite ends of the guides to be
moved simultaneously toward or from each other.
Each of the guides is slotted horizontally at the end thereof next the feed-end of
the machine to receive the shark of an adjusting screw which is secured to a block
having pivoted thereto a gauge-carrier. A laterally extending finger on said gauge-
carrier is slotted to surround a threaded post on said block, and a spring surrounds
the said post between its head and the slotted finger. An internally threaded collar
or nut engages the threaded portion of the post between the block and the slotted
.1

page_text: finger. The gauge-carrier is slotted longitudinally to receive the shank of a
clamping screw that is attached to a vertical gauge. The two vertical gauges at
the opposite sides of the machine determine the position to be occupied by the side
of the blank or pile of blauks which is nearer the feeding end of the machine. By
moving the blocks aforesaid bodily along the guides and securing them in place by
adjusting screws, the gauges are given approximately the desired position in the
direction of the length of the machine. The said gauges may be adjusted to the
desired extent toward or from the centre of the machine on the gauge-carriers and
secured in the desired position on the latter according to the length of the blanks.
After the blocks have been adjusted and secured in place, thus bringing the vertical
gauges approximately to the desired position lengthwise of the machine as aforesaid,
an extremely fine and exact adjustment may be given to each of the gauge-carriers
and its gauge by turning the nut or collar on the threaded post aforesaid, such
movement turning the gauge carrier on its pivot.
It happens sometimes that when the blanks are cut from thin or light stock the
ends thereof beyond the slotted portions, if not supported so as to prevent them
from bending, will fall below the level of the tracks out of a horizontal plane, after
receiving the paste. This results in an improper presentation of the blank to the
former. To obviate this bending, and present the blank always in a horizontal
plane, adjustable auxiliary tracks are provided laterally outside of or beyond the
side tracks aforesaid. These auxiliary tracks are mounted upon the side-guides
for the blanks, and are made adjustable both laterally and longitudinally with
relation thereto. The side tracks before referred to as being secured to the paste
pans move with the said paste pans when the latter are adjusted laterally. An
end-gauge or finger is placed in position for engagement with the leading ends of
the blanks as they lie between the side guides aforesaid. The said end-gauge or
finger is movable vertically in a grooved head having laterally extended ears or
flanges to enter guide-ways in a bracket that is secured to or forms a part of the
head of the machine, clamping plates being bolted to the undersides of the bracket
so as to form the bottoms of said guide-ways and maintain the head in horizontally
adjusted position according to the width of the blank. The upper end of the end-
gauge or finger is engaged by an adjusting screw whereby the said end-gauge or
finger may be raised or lowered according as the blanks are of different thicknesses,
so that but one blank can be moved forward under it at the same time. Inasmuch
as different blanks in the pile of blanks will vary in thickness somewhat, the end-
gauge or finger is adjusted vertically by the means described, so as to permit the
passage thereunder of the thickest blank that may be in the pile, and an end wise
yielding gauge-plate is secured to the beveled lower end of the end-gauge or finger,
the said gauge-plate normally leaving sufficient space for the passage thereunder of
a blank of average thickness. Should a blank which is thicker than the average
be presented, its leading edge will engage the exposed end of the yielding gauge-
plate, and in its advance will press the same slantingly upward along the beveled
under end of the end-gauge or finger until said end of the gauge plate has been
raised sufficiently to permit of the passage thereunder of said blank. After the
blank has been carried forward and positioned by the feeder the yielding finger
will be moved back into its normal position, preferably by a spring. It is
important to maintain the blank perfectly flat after it has been carried forward
beyond the end-gauge or finger. In order to accomplish this, there is secured on
the front of the grooved head one part of an adjustable presser-foot, the said part.
preferably being made as a longitudinally curved metallic plate which is slotted at
its end adjacent the head to embrace the end-gauge or finger and permit the
movement of the yielding gauge-plate, the said curved plate being held in position
on the head by screws extending through vertical slots in an ear or lug in the said
plate, the slots enabling the plate to be adjusted slightly in a vertical direction
according to the thickness of the blanks. The other part of the presser-foot is
formed, preferably, as a curved plate, supported by an upturned arm thereon which
is connected to a carrier that is adapted to slide and be maintained in adjusted

page_text: position in a suitable clamp. The construction of the presser-foot is such that the
two parts thereof may be moved upon or relatively to each other so as to vary
their combined length, the said length' being varied by moving one part of the
presser foot toward or from the former, hereinafter to be described, according to
the width of the blank to be fed to the said former. The presser foot bears-upon
the upper side of the blank after it has been fed' forward beyond the end-gauge,
and maintains it perfectly flat as it is presented to the former. A spring stop is
secured to the underside of the movable part of the presser-foot, the said stop rising
to permit the passage of the blank as it is fed forward, but dropping back into its
normal position behind the rear edge of the blank as soon as the blank has been'
moved beyond the stop, to prevent any possibility of the blank sticking to and being
retracted by the feeder on the rearward movement of the feeder.
The side tracks terminate a slight distance beyond the forward edge of the tank
which contains the wetting devices and the paste boxes hereinafter referred to.
Continuations of said tracks are formed on the inner edges of longitudinally
corrugated side plates which are secured adjustably to the bed plate of the machine
adjacent to the former. The corrugations on said plates support the projecting
ends of the blank when the latter is in position over the former; and also afford a
clearance space for any dirt or scraps of material which may adhere to the under-
sides of the blanks. The grooved side plates are also grooved at their under sides
to receive the flange portions of filling plates which are located at opposite ends of
each side plate, at the front and rear of the former respectively. Said flange
portions are clamped between the side plates and the bed-plate when the securing
screws for the side plates are tightened to effect the securing of the said side plates.
When the said screws are loosened, each side plate and the adjacent filling plate
may be adjusted laterally simultaneously, or as one piece, upon or with relation to
the bed-plate of the machine, to adapt the machine for a longer or shorter former
and blank, and the filling plates may be adjusted or slid longitudinally with relation
to the side plate to provide for variations in the width of the box. Tightening the
said screws clamps the side and filling plates securely in adjusted position. To
avoid carrying the middle track up to the former, in order to support the middle
of the blank at its underside, each of the filling plates at the rear side of the former
has pivoted to the inner longitudinal vertical face thereof a yielding track-like
support or finger having the forward end thereof 'extended nearly to the rear side
of the former, the said forward end normally being held a little above the top of the
filling plate by a suitable spring. As the blank is fed forward and its leading edge
passes from the end of the middle track it rests upon the tops of these yielding
supports, and as the feeder completes its forward movement the said supports are
compressed momentarily and the middle portion of the underside of the blank rests
upon and is supported by them after the retraction of the feeder. By cutting away
the middle track and securing the yielding supports to the adjustable filling plates,
it is possible to obtain a much greater adjustment for the width of the box or cover
to be made than otherwise would be the case.
1
Each side guide is grooved longitudinally at its front end to receive a slide which
is held in its adjusted position in said groove by a screw, each of the said slides
having attached thereto an edge guide extended vertically upward, the said edge
guides acting as stops to position the blank when the same is ready to be moved
vertically by the former, so that the blank will be raised in a truly horizontal
position. Projecting ledges at the lower edges of the side guides support the
extreme edges of the blank and form a sort of track to keep the pasted portions of
the blank from contact with the fixed side plates.
4
The bed-plate is cut away at the point where the pile of blanks is supported and
has secured thereto the vat or pan which contains the water to be used for wetting
the blanks prior to feeding the same and also encloses the wetting and pasting
d'évices.
"The wetting devices or wetters consist of a series of blocks that are grooved or
recessed at their upper ends to receive sections of felt or other absorbent material

page_text: which constitute their acting surfaces. These blocks are recessed at their under-
sides to receive loosely the conical ends of bearings provided on skeleton holding
frames which are supported in longitudinally recessed or grooved supports.
Certain of these grooved supports extend transversely of the machine and are
secured to blocks which are adapted to slide horizontally toward and from each
other on standards secured to a yoke that is mounted upon or fixed to a spindle
extended up through a suitable stuffing box which is in the bottom of the vat, the
said spindle being vertically reciprocated to cause the wetters to be raised and
lowered in the vat. Movement is transmitted to the said spindle from a cam on
the cam-shaft through suitable operating connections. Certain of the grooved
holding frames are disposed at right angles to those just above described, namely,
longitudinally of the machine, and are supported upon uprights that are secured to
slides which are adapted to be moved laterally on the yoke toward or from the middle
of the machine, the said elides also forming the bases of spindles which extend
through'suitable stuffing boxes in the bottom of the paste pans, lateral adjustment
of the said paste-pans and the said spindles also adjusting the longitudinal wetters,
the said slides being held in adjusted position laterally on the arms of the yoke by
suitable securing means, such, for example, as clamping screws. Inasmuch as the
side tracks are secured rigidly to the paste pans, and the longitudinal or end
wetters are also secured to the slides on which the paste-paus are mounted, any
lateral adjustment of the paste pans will also be accompanied by a simultaneous
adjustment of the side tracks and end wetters so that they will always be main-
tained parallel and at the same distance apart, the one adjustment answering for
all. Slots are formed in the inner sides of the end wetter holders and when a very
long blank is used the transverse wetting devices are extended, the outer ends of
the endmost holding frames resting in the said slots while the inner ends of the said
frames rest in and are maintained upright by the grooved supports above referred
to. The slots are of sufficient length to admit of considerable adjustment of the
transverse wetters.
The pasters consist of a series of blocks which are grooved at their upper edges
and also are slotted or forked to embrace and rest upon flexible tubular bearings
which are mounted upon the longitudinally grooved upper sides of notched bars.
The notches serve to keep the blocks in position parallel to each other, and to
prevent them from twisting upon the bars, which latter are mounted on cross-bars
that are suitably supported at the upper ends of the spindles aforesaid. The said
notched bars may be more or less filled up with the pasters according to the size
and shape of the part of the blank to which it is desired to apply the paste. For
instance, alternate bars, only, may have pasters applied thereto, as when it is
desired to apply paste to a blank on separated lines. The cross-bars are supported
yieldingly by springs, on the upper ends of which they rest.
When the pasters
rise with the wetters, they rise up through the paste in each paste-pan and lift
portions of the paste up against the blank at the bottom of the pile of blanks. The
grooved tops of the paste blocks retain in them more or less paste, the quantity
depending upon the depth of the grooves. The wetters and the pasters having
operated simultaneously on the blank to wet the same and paste it at the
proper places, the actuating mechanism of the feeder then moves the latter forward
to engage the wet and pasted blank and carry it forward along the tracks into
position above the former. Standards are secured to the bottom of the tank to
support guide ways for the underside of the feeder in its reciprocations, the central
track being supported by a cross frame which is secured to the guide ways. Other.
guide ways are provided at the rear and front of the tank.
The former over which the blank is bent to give shape to the box or cover is
adapted to rise and fall through an opening in the bed-plate of sufficient size to
accommodate the largest former to be used, the effective opening for the passage
of the former being adjusted and formed by the longitudinal grooved side plates
and filling plates heretofore described, which are set to suit the size of the former
to be used. The under side of the former is secured to the upper end of a

page_text: reciprocating cross-head that is guided in ways on the machine framing; it having
rack-like bars. secured to or forming. part of the vertical sides thereof to be
-engaged hy gears which are secured to a short shaft carrying a pinion which is in
mesh with a rack that is acted upon by a cam on the cam shaft. By the action. of
this cam, the rack is reciprocuted and through the gears and short shaft referred
to the cross-head and former are reciprocated vertically. The rigid guide-ways
for the former render vibration thereof impossible, the actuating mechanism
-described insuring a positive, powerful and steady reciprocation of the former.
The follower which co-acts with the former is secured detachably to the lower
end of a slotted slide rod that is extended through a sleeve forming a fixed yoke-
like portion of the head of the machine framing, said follower moving vertically
within the said head. A cylinder is secured to the upper end of the slide-rod and
receives therein a piston which is secured to a piston rod that is extended within
and guided by the slotted slide-rod. The piston-rod is held in its normal position
by a latch mounted upon the sleeve, the end of the latch engaging a recess in
the lower end of the piston rod. A small vent or opening is made in the top of the
cylinder, through which air enters into or is discharged from the cylinder above the
piston. When the follower is raised, the air underneath the piston forms a cushion
preventing sudden shocks, and the space above the piston is filled with air, so that
when the follower descends the air will be slowly expelled through the vent and
the descent of the follower will be cushioned thereby. In order that the air may
pass from the under side to the upper side of the piston, the latter is provided
with a small passage. The weight of the follower is increased and its movement
steadied by attaching a heavy. annular weight to the cylinder. The lower end of
the slide rod is reduced and provided with oppositely extended ears, while the
follower has a hub formed on its upper side, in the opening of which are two
opposite inwardly projecting ledges having between them a narrow opening to
receive the end of the slide rod. The said end is inserted through the said
opening until the ears on the slide rod pass below the plane of the said ledges in
the hub, after which the follower is turned through an are of 90°, thus bringing the
ears beneath the ledges and supporting the follower on the slide rod, the shoulder
on the slide rod above the ears preventing the follower from being displaced. The.
follower is held from any rotation upon the slide-rod, when in place in the machine,
by the side and end wiper plates. order to enable the follower to be removed
or replaced, the latch aforesaid is disengaged from the piston-rod, permitting the
latter to drop and consequently allowing the slide rod to fall through the sleeve
until the bottom of the cylinder rests upon the top of the sleeve. The follower
thus is brought below the lower edges of the wiper plates, and it then can be
rotated upon the slide rod sufficiently to enable it to be removed therefrom. In
practice the area of the follower is slightly greater than the area of the former, the
difference being usually about of an inch.
The side wiper plates are supported in an adjustable manner on cross-braces
located at the front and rear of the follower, they being provided with extensions
which are rectangular in cross-section and fit in guide-ways in the cross-braces.
Each extension is engaged by an adjusting rod or screw by means of which the
corresponding side wiper plate may be moved in and out toward or from the
follower and former according to the thickness of the blank to be acted upon or
the size of the former to be used.
Suitable brackets are secured to the outer faces of the side wiper plates and are
provided with bearings for like rock-shafts, each having a longitudinal groove
therein, the said bearings being located at the lower ends of the side wiper plates and
at the extremities of the rock-shafts, and they are at such a distance apart that the
side and lip-turners presently to be referred to may be adjusted outwardly along
the rock-shafts to the extent required for the largest size of box or cover to be
made on the machine. The said rock-shafts are provided with beveled gears in
engagement with like gears that are secured to and rotatable with an actuating
shaft, the latter being supported in bearings in certain of the brackets above

page_text: referred to as mounted on the side wiper plates. The beveled gears on this.
actuating shaft are moved longitudinally thereof by the adjustment of the side.
wiper plates. A pinion on the said actuating shaft is engaged by a reciprocating
rack-bar actuated through suitable connections by one of the cams on the cam--
shaft.
The side and lip turners which are mounted on the said grooved shafts are
adapted to act upon the blank, first to turn the side flanges thereof down bodily
upon the vertical faces of the former, and thereafter to bend the lips or flaps at
the ends of the said sides about the corners of the former and over upon the end
faces thereof, and to hold the portions so bent in such position until the former in
its continued vertical movement has carried them above and beyond the side and
lip turners and against the inner faces of the side wiper plates, the said side wiper
plates maintaining the side of the box or cover against the former while the end
wiper plates are moved forward to compress the pasted ends of the blank upon the
Corner Haps, the said ends having been previously bent down as will be described.
The side and lip turners are composed of plates or wings, the side turners being
provided with hubs loose on the grooved shafts. Other hubs are splined to the said
grooved shafts to rotate therewith, each of said hubs having thereon a segment beveled
gear to engage a similar gear on the end of a pintle which is extended through suitable
like ears on a side turner plate and a lip turner plate, a set screw being extended
through one of the ears of the lip turner to cause the latter to move with the pintle
when it is rotated on its own axis. A spring applied to the parts normally unfolds.
the lip turner and maintains it in the same plane with the side turner. Until. the
former has raised the blank against the follower the folding plates forming the side
and lip turners are held unfolded or extended, the grooved shafts occupying
positions which cause the said plates to assume outwardly directed positions.
horizontally. When the blank has been clamped firmly between the former and
follower, and before it is carried upwardly between the side and end wiper plates,.
the grooved shafts are rotated in a direction to positively swing the side and lip
turners, which are still extended or unfolded, down from their horizontal position
into vertical planes parallel to the front and rear faces of the former, thereby
bending the projecting side flanges of the blank over against the vertical sides of
the former, the springs being of sufficient strength to maintain the lip turners in.
unfolded or open condition and cause each pair of connected plates or turners to
move as one in over-coming the resistance offered by the blank to the bending of
its sides. As soon, however, as the sides of the blank are brought against the
vertical faces of the former, further movement of the side-plates or turners is
prevented thereby, and as the grooved shafts continue to rotate, the geared hubs
moving therewith and engaging the segment gears on the pintles will rotate the
said pintles in the ears of the side turners, thereby turning the lip turners into
positions at right angles to the side turners and bending the lips or flaps at the ends
of the side flanges of the blank sharply around the vertical corners of the former
and presenting each bent lip or corner flap against the ends of the former. The
compound side and lip turners are held in adjusted position upon the grooved shaft
and are restrained from movement longitudinally thereof by clamp collars which
can be clamped rigidly upon the shafts at the desired points, said collars preventing
longitudinal movement of the side and lip turners. The cam which acts to
reciprocate the rack-bar by which the grooved shafts are operated is of such shape
that the side and lip turners are maintained folded and closed upon the blank until
the former has moved upward sufficiently to carry the blank above them and into
position to be held by the side and end wiper plates.
Four pressure screw shafts extend across the head of the machine and have
secured to their opposite ends similar gears, all of the said gears at one end of the
series of said shafts being engaged by a reciprocating rack and all of the said gears
at the other end of the series being engaged by a similar rack. Each of the said
racks is actuated by a cam on the cam-shaft. Two of the said shafts are provided
at the left-hand side of the machine with right-hand screw threads while at the

page_text: :
right-hand end of the machine said shafts are provided with left-hand screw threads.
The other two shafts atithe right hand side of the machine are provided with
right-hand screw threads and at the left hand side of the machine are provided
with deft hand screw threads. A pressure head is supported on the threaded
portions of the said shafts at the right hand side of the machine, and a like pressure
head is supported at the left-hand side of the machine by the threaded portions of
.sáid'shafts at that end thereof, each of the said pressure heads having at each of
its ends two sleeve like nuts and each of said nuts. fitting the thread on one end
of one of the pressure shafts. The engagement of these nuts with the threads of
the shafts provides for moving the pressure-heads positively backward and forward
along the pressure shafts by the rotation of the latter, the said pressure-heads being
moved to carry the end wiper-plates thereon up against the partially made box
held upon the former to compress the pasted ends of the box upon the corner flaps,
previously turned over as described. Each nut is mounted loosely in its pressure
head so as to rotate therein and has attached to it a pinion or gear, and with the
set of pinions or gears of each pressure head are combined intermediate gears and
a worm gear which is engaged and adapted to be rotated by a worm on a vertical
shaft which is provided with a suitable bandle by means of which it may be turned
by hand when it is desired to adjust the pressure heads toward or from each other
to adapt the end wiper plates carried by them to the thickness of the blank, and
also to the size of the particular former to be used... With the pressure-heads properly
adjusted to the size of the blank they are reciprocated toward and from each other
during the completion of each box or cover, and toward and from the former, by
.the reciprocation of the racks which engage with the gears carried by the pressure
screw shafts. The end wiper plates are not rigidly held to the pressure heads, for
if they were the result would be that in case of any irregularity in the thickness of
the blank on the former the thinner portion of the blank would not be subjected to
sufficient pressure, and, particularly, the corner:where the stock was thinnest would
not be properly pasted smooth.or united. To obviate this trouble, each end wiper
plate is applied to a bearing block having preferably a convex back to rest in a
suitable concavity in the pressure head as a seat, said block being adapted, to rock
on or about vertical pivots. The lug containing the bearing for the upper of said
pivots is pivoted and held in position by a spring catch. Should it be necessary
for any reason to remove an end wiper plate, the spring catch is withdrawn, and, the
lug swung to one side to disengage the pivot, after which the .wiper plate readily
may be moved out of its seat. The pressure head has recesses formed therein on
opposite sides of the vertical concavity in its face, şaid recesses being threaded. to
receive threaded sleeves which are provided at their inner ends. with polygonal
heads by which they may be rotated and adjusted in the recesses. Headed shanks
are extended through the sleeves and nuts are secured upon their projecting inner
ends to prevent them from being forced outwardly by the pressure of coiled springs
surrounding said shanks within the sleeves. The springs bear upon the heads. of
the shanks and the inner ends of the sleeves. The outer ends of the shanks bear
against the backs of the bearing-blocks at opposite sides of the convex portion,, so
that the end wiper plates. and attached blocks are free to rock slightly in the
pressure-heads and thereby adapt. themselves to any variation in the thickness, of
the ends of the blank, longitudinal adjustment being made by moving the threaded
sleeves in or out of the recesses, as may be necessary.

I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 :-
My invention has for its object the production of a rapidly operating machine
adjustable within very wide limits for the manufacture of paper boxes and their covers,
whereby the stock from which they are made whether heavy or light, may be acted
upon with equal facility, and the finished article accurately and quickly produced.
In my improved machine, as will be hereinafter described, the blanks from which
the boxes or covers are to be made are placed in position between adjustable guides
located above a tank containing wetting devices and pasting devices, the undermost
blank of the pile of blanks being supported between its ends on suitable tracks, the
wetting devices rising at the proper time and wetting the said .undermost blank
transversely and longitudinally along the lines on which it is to be subsequently
folded to form the flanges or sides and ends of the box or cover, the width of the
said flanges depending on the depth of the box or cover to be made, while the
pasting devices also rise and apply paste to the desired parts of the blank to be
turned over in order that other parts of the flanges may be pasted to them. The
blanks of the pile are thereafter fed forward by a feeder one by one from the bottom
of the pile along supporting tracks into position between a former and a follower,
both of which latter are made movable vertically with relation to said tracks or to
the bed of the machine, the wet and pasted blank being carried up by the former to
the follower and caught and held between them, and while it is thus held the
projecting portions of the blank are subjected to the action of side and lip turners,
which latter positively turn the side and corner flaps of the blank over the former
after which the former further rises with the blank, still taking with it the follower,
and moving the blank held between them past side and end plates or wipers, the
last of which causes the end flaps of the blank to be wiped or turned down upou
the corner flaps or lips, the latter having been previously turned over and held upon
the former by the side and lip turners. As herein shown, the side and lip turners
are connected and move together, the flanges or edges of the blank which are to
constitute the sides of the box or cover are first turned down by the side turners,
after which continued movement of the lip turners fold the latter around the
corners of the former, and turns the corner flaps or lips of the blank snugly about
the corners of the former, the side and lip turners remaining stationary in such
position and holding the side and corner flaps against the sides and ends of the
former, until further vertical movement of the former causes the end flanges or flaps
of the blank to be turned over upon the corner flaps. When the end flanges or
flaps have been thus turned down against the corner flaps, the former has reached
the limit of its upward movement and it is arrested. The blank is then subjected
to compressing mechanism to complete the sides and ends of the box or cover, after
which the former, the follower, and the side and lip turners return to their normal
positions, and an ejector delivers the completed box or cover from between the
separated former and follower.
The invention will be described first with reference to the accompanying
drawings, after which the characteristic features thereof will be particularly
pointed out in the claims at the close of this Specification.

page_text: At C is the main or driving shaft, it having loose thereon a belt pulley C³
forming one part of a friction clutch C', see Figs. 2 and 34, the latter being of any
usual or well known construction rotatable with the driving shaft. C³ and operated
by the usual cone C³, Figs. 2 and 34, which is actuated by a yoke C on a
rock shaft C10 that is operated through the medium of the lever C" and its
connections.
It is most desirable to be able to stop the machine very quickly at times, and in
order to do so, I have secured to the driving shaft C a brake wheel B', see
Figs. 1, 3, 5 and 34, adapted to be engaged by a friction shoe B³ secured to a
carrier B³ pivoted at 80 to the base of the machine, said carrier being pivotally
secured to an internally threaded collar B₁ engaging with the threaded end of a
rod B³, the other end of said rod, also threaled, entering a similar threaded
sleeve B pivoted to a suitable stand B7 said rod having formed thereon or secured
to it between its ends a toothed gear B³, Figs. 3, 34, and 35, in engagement with
the teeth of a rack bar B' which is slotted to embrace the said gear, and is
connected by a rod Bo to an arm B of the rock-shaft C1º.
When the lever C₁ is moved to the left, viewing Fig. 2, the clutch will be
moved into engagement with the belt pulley C to render the same fast on the main
or driving shaft, the movement of the rock-shaft C10 also moving the rod B10 to the
left, Fig. 2, and the rack-bar B at such time rotating the threaded rod B' in its
sleeve-like bearings B and B to thereby draw the shoe and its carrier B³ toward
the sleeve B and away from the brake-wheel B'.
When the machine is running and it is desired to stop it, the hand-lever C¹¹ is
moved to the right, Fig. 2, thereby throwing the clutch out of engagement, and
at the same time rotating the threaded rod B in the proper direction to move the
carrier B toward shaft C' and force its shoe B2 firmly against the brake wheel in
a most powerful and efficient manner, the power applied to the shoe being great
enough to deflect the main shaft C were it not for the guard shoe B" pivotally
supported at the opposite side of the brake wheel, as clearly shown in Figs. 1, 3, 5
and 34.
The application of the brake is simultaneous with the releasing or disengagement
of the clutch and is so effective and rapid in operation that the machine may
be stopped, when running at full speed, in less than half a revolution of the
main shaft.
At C is a pinion on the main or driving shaft C engaging with a large gear (*
on the shaft C the latter being supported in suitable bearings and also having
thereon a pinion C', see Fig. 5, that engages with a toothed gear C fast on the
cam shaft A which is mounted in bearings A3 A3 provided with suitable pedestals
carried by the side frames and base of the machine. The gear C has formed in
the side thereof a cam-groove Cx as shown in Figs. 27, Sheet 7. In addition, the
cam-shaft A has mounted thereon a series of cams B, D, E and F, these latter
being shown separately in Fig. 28, Sheet 4; Fig. 29, Sheet 7; Fig. 30, Sheet 7,
and Fig. 31, Sheet 4, respectively there being a cam B at each end of the cam-shaft
and the two cams B being oppositely fixed.
The link E, Figs. 1, 3 and 5 is shaped at one end to form a guide slot E³, see
more particularly Figs. 1 and 3, to embrace the cam-shaft A' the said link E³
having thereon a suitable roller or other stud E to engage and be actuated by the
cam surface Ex of the cam E, shown separately in Fig. 30, Sheet 7, the guide slot
acting to steady the link in its movements as it is reciprocated by the cam.
opposite end the link E³ is pivotally connected at E to an arm El preferably formed
as a trussed structure, said arm being pivoted at E to a suitable support on the
base of the machine.
At its
The arm E¹ is herein shown as a truss, combining strength and rigidity with
lightness of construction, although it is obvious that any other suitable or desirable
construction may be used.
The bed-plate A' is rearwardly extended at the feed end of the machine, see

page_text: Figs. 1, 14, and 4, Sheets 1, 4, and 7, and undercut plates a are secured thereto to
form longitudinal guides or ways for the frame G, see Fig. 14, Sheet 7, Fig. 4,
Sheet 4, and Fig. 6, Sheet 6, to which is adjustably secured the feeder G' by
suitable bolts g, the said frame G which is shown separately in Fig. 6, Sheet 6,
being connected to the upper end of the arm-E' by a short link g' shown in section
in Fig. 3, and in dotted lines in Fig. 1, and thereby being reciprocated horizontally
back and forth in the guide ways a¹.
The adjusting bolts g are extended through longitudinal slots g³ of the feeder G',
see Fig. 4, Sheet 4, whereby the position of the forward end of the feeder is
adjusted to the width of the blank M, see Fig. 36, Sheet 1, to be acted upon, such
adjustment being necessary to adapt the machine to various widths of blanks,
inasmuch as the throw of the frame G is constant.
The feeder G¹ is slotted at midwidth at G2, see Fig. 4, Sheet 4, and Fig. 7,
Sheet 6, to enable it to pass the middle track b, to be described, the said track
extending to within a short distance of the former, as best shown in section,
Fig. 3.
The forward end of the feeder G' is beveled as at 2, Figs. 4, Sheet 4, and Fig. 7,
Sheet 6, to readily pass under the blank, the said fecder immediately back of the
heveled front end 2 having attached to it plates 98, the front edges of the said
plates meeting one of the long sides of the blank in the movement of the feeder in
the direction of the arrow 200, Fig. 4, the contacting edges of the said plates
preventing the blank from slipping on the feeder while being fed. The plates g³
are attached to the feeder by suitable screws 3, whereby they may be readily
removed and replaced when worn.
Side tracks 6 parallel to the middle track bare located at opposite sides of the
said middle track b said tracks being secured to the upper portions of the paste
pans H at the inner sides of the latter and serving to support the blank between
the points where the said blank is wet and where it is pasted. or just outside
the line on which the blank will he folded to constitute the ends of the box or
Cover.
The blanks M of paper-board, all properly notched as in dotted lines, Fig. 36,
Sheet 1, to form end and corner flaps and side flanges, are placed in a pile between
suitable guides K-herein shown as plates, see Fig. 3-having at their opposite
ends internally threaded bearings k, l, respectively, see Fig. 4, to receive therein
the right and left-hand screw threaded adjusting guide rods K', K³, the said guide
rod K being supported in suitable stands erected upon the bed-plate A' and the
said guide rod K³ in brackets ³ secured to the head of the machine. Like
bevel-gears are secured to the rods K' K best shown in Fig. 4, to engage
gears and k³ on a connecting shaft suitably supported in bearings on the bed
plate A', and as herein shown one end of the rod K³ is shaped to receive a crank
arm k', see Figs. 1 and 2, whereby it may be rotated, such rotation by means of the
described bevel gears and connecting shaft also rotating the rod K', to
simultaneously move the opposite ends of the guides K towards or from each other,
thereby maintaining them in parallelism, the described arrangement enabling the
operator to rapidly and accurately adjust them to the length of the blank.
Each of the guides K is horizontally slotted at the end thereof next the feed end
of the machine, as at k³, see Figs. 1 and 3, to receive therethrough the shank of an
adjusting screw secured to a block 0 provided with a fin 20 shown in Fig. 8,
Sheet 6, to enter and be guided by the longitudinal recess at the inner side of
the guide K, see Fig. 3, the said block having pivoted thereto a gauge carrier k¹³,
Figs. 3, 4 and 8, extending laterally from the inner side of the guide, and which
carrier is provided with a slotted finger surrounding a threaded post k¹. A
springs, Fig. 8, surrounds the said post between its head and the finger k" and an
internally threaded collar or nut engages the threaded portion of the post
between the fin 20 of block ko and the finger k". The gauge carrier is slotted
longitudinally to receive the shank of a clamping screw 5 attached to the vertical

page_text: gauge . The two gauges 17 at the opposite sides of the machine determine the
position to be occupied by the rearmost side of the blank or pile of blanks, that is
to say, the side thereof which is nearer the feeding end of the machine. The main
adjustment of the gauges 7 is made by moving the blocks 10 bodily along the
guides K and securing them in place by the screws k³. In this manner the said
gauges are given approximately the desired position in the direction of the length
of the machine. The gauges may be adjusted to the desired extent toward or
from the center of the machine on the gauge carriers and secured in the desired
position by the screws 5, according to, the length of the blanks. After the
blocks 10 have been adjusted and secured in place, thus bringing gauges k" to their
proximate position lengthwise of the machine as aforesaid, a finer and extremely
exact adjustment may be given to each of the carriers and its gauge by turning
the nut or collar on the threaded post, such movement turning the gauge
carrier on its pivot and enabling a very fine adjustment of the vertical gauges
to be made.
It sometimes happens, when the blanks are cut from thin or light stock, that the
ends thereof beyond the wetted portions, after receiving the paste, will bend or fall
below the level of the tracks b, 61 or out of a horizontal plane, if not supported so
as to prevent them from thus bending, this resulting in an improper presentation of
the blank to the former. To obviate this bending, and always present the blank in
a horizontal plane, I have provided adjustable auxiliary tracks 62 laterally outside
of or beyond the tracks 61 as best shown in Fig. 4. The lower flauge or base of
each guide K is slotted longitudinally, as at 6* see dotted lines, Figs. 1 and 4, to
receive therein an upturned threaded shank of a clamp block 63, and between the
top of the clamp and the bottom of the guide is extended a lateral extension 6*
connected with the adjacent auxiliary track 6 and having a longitudinal slot bl*,
the threaded shank of the clamp block extending upward through the slot in said
extension and having at its upper end a suitable clamping nut 65. By loosening
the clamping nuts 66 the pressure exerted by the clamp blocks upon the lateral
extensions is relieved and the slots 6x 6x enable the auxiliary tracks 62 to be
moved toward or from the guides K, and also longitudinally along the said guides
so as to adapt them to blanks of various sizes.
The side tracks are secured rigidly to and adjusted laterally with the paste
pans H, the said pans being provided at the ends thereof with the slotted horizontal
flanges h, see Figs. 4, 9, Sheet 7, and 10, Sheet 6, which rest on suitable
supports to be hereinafter described, forming parts of the tank H¹, screws 6
being extended through the slots of the flanges and into the said supports to hold
the paste pans H in the desired positions of lateral adjustment.
An end gauge or finger c is placed in position for engagement with the forward
erds of the blanks as they lie between the guides K, K, see Fig. 3. This end
gauge c is vertically movable in a suitable grooved head c' having laterally extended
ears or flanges at its upper end, see Fig. 12, Sheet 3, to enter guide-ways c
Fig. 3, in brackets c, Figs. 1, and 4, secured to or forming a part of the head of
the machine to be described, clamping plates c, see Fig. 3, bolted to the underside
of the brackets and forming the bottoms of said guide-ways, maintaining the
head c¹ in horizontally adjusted position, according to the width of the blank. The
upper end of the end gauge or finger c is engaged by the lower flange of the hend
of an adjusting screw c' having its bearing in the head c' rotation of the said screw
in one or the other direction raising or lowering the gauge or finger to accommodate
blanks of different thicknesses, so that but one blank can be moved forward under
it at the same time. Inasmuch as different blanks in the pile of blanks will vary
somewhat in thickness, the gauge or finger is vertically adjusted by the means
described so as to permit the passage thereunder of the thickest blank that may be
in the pile, and an endwise yielding gauge plate cx, Fig. 3, Fig. 12 Sheet 5, and
Fig. 13, Sheet 7, is secured to the beveled lower end of the finger or end gauge c,
by a screw c*, Fig. 13, passing through a slot in said gauge-plate into the said
lower end of the end gauge c, the said gauge plate normally leaving sufficient space

page_text: beneath the same for the passage thereunder of a blank of average thickness.
Should a thicker blank than the average be presented, its leading edge will engage
the exposed end of the yielding gauge-plate c* and will press the same slantingly
upward along the beveled under end of the end gauge or finger c until said end of
the gauge plate c* has been raised sufficiently to permit the passage thereunder of
said blank, and, after the latter has been carried forward and positioned by the
feeder, the yielding finger will be moved back into its normal position, preferably
by a spring x acting thereon, as in Fig. 13.
It is important to maintain the blank perfectly flat after it has been fed forward
beyond the end gauge or finger c, and in order to accomplish this, I have secured
to the front of the grooved head c', une part es of an adjustable presser-foot,
see Fig. 12, Sheet 5, and 14, Sheet 3, shown as a longitudinally curved metallic
plate, slotted at eat its end adjacent the head see Fig. 4, Sheet 3, to embrace
the end gauge or finger, aud permit the movement of the yielding gauge plate c*,
the curved plate being held in position on the head c' as shown in Fig. 3, by set
screws 7 extended through vertical slots in an arm co of the said plate, whereby
the latter may be slightly adjusted in a vertical direction according to the thickness
of the blanks. The other part of the presser foot is also shown as a curved plate c¹²
cut away or slotted at 18 and supported by an upturned arm c" thereon which is
connected to a carrier c adapted to slide and be maintained in adjusted position in
a suitable clamp c one-half of which is shown in Fig. 3, see also Fig. 12, Sheet 5,
the grooved head c and end-gauge or finger c having openings therein to receive
the end of the carrier, as best shown in Figs. 3 and 12. In Fig. 3, the two parts
of the presser are shown as pushed in, one upon the other, while in Fig. 12, Sheet 5,
and Fig. 14, Sheet 3, they are shown as drawn out or extended in order to more
clearly illustrate their construction and manner of adjustment. The part c" of the
presser is moved toward or from the former, to be described, according to the
width of the blank to be fed, and it will be seen from the foregoing description and
an inspection of Fig. 3, that the presser foot will bear upon the upper side of the
blank after it has been fed forward beyond the end gauge c, maintaining it perfectly
flat as it is presented to the former.
A spring stop, Fig. 3, is secured to the underside of the plate " and extended
to the end thereof nearer the former, the said stop rising to permit the passage of
the blank as it is fed forward, but dropping back into its normal position shown in
Fig. 3, behind the rear edge of the blank as soon as it has been moved beyond the
stop, to prevent any possibility of the blank sticking to and being retracted by the
feeder on its rearward movement, as such retrograde movement would obviate its
proper presentation to the former.
The side tracks 6' terminate a slight distance beyond the forward edge of the
tank H¹, see Fig. 4, which contain the wetting devices and the paste boxes, to be
described, continuations of the said tracks being shown at 6x, Fig. 1, and Figs. 22,
23, Sheet 6, formed on the inner edges of the longitudinally corrugated side
plates 6, the said side plates being adjustably secured to the bed-plate A¹ as will
be described, adjacent to the former, the corrugations on said plates supporting the
projecting ends of the blanks when the latter is in position over the former, and
also affording a clearance space for any dirt or scraps of material which may adtere
to the undersides of the blanks.
The side plates 66 are grooved at their undersides as at 7 best shown in Fig. 2,
to receive the flange portion d of the filling plates d', shown only in Fig. 2, and
omitted for the sake of clearness in Fig. 3, the said flange portions being clamped
between the plates 6 and the bed-plate when the securing screws or bolts d²
that are extended from beneath through lateral slots d' Fig. 23, in the bed-plate,
and into the corrugated plates 66, are tightened to effect the securing of the
plates 6º.
When the screws or bolts d² are loosened each of the plates 6 and the adjacent
plate d¹ may be simultaneously adjusted laterally as one piece with relation to the
bed-plate A' of the machine to adapt the same for a longer or shorter former and

page_text: blank, and the filling plates d' may be adjusted or slid longitudinally with relation
to the side plates 6 to provide for variations in the width of the box. Tightening
the securing screws clamps the side and filling plates securely in adjusted
position.
A filling plate is located at each end of each side plate 60 at the front and rear-
of the former, respectively, but in order to avoid carrying the middle track up to
the former in order to support the middle of the blank at its underside, I have
pivoted to the inner longitudinal vertical face of each of the filling plates d', at
the rear side of the former, a yielding-track-like support or finger d³, see Fig. 3,
Fig. 15, Sheet 7, and Figs. 22 and 23, Sheet 6, the forward end of said support or
finger extending nearly to the rear side of the former, and being normally held a.
little above the top thereof by a suitable spring, such, for instance, as that shown.
at Fig. 15, Sheet 7, coiled upon the pivotal pin d of the said support, or
finger d, it having an end fast to the said pin and the other to the filling plate d'..
As the blank is fed forward and its leading edge passes from the end of the middle
track, it rests upon the tops of these yielding supports, and as the feeder G
completes its forward movement they are depressed thereby momentarily, and the
middle portion of the underside of the blank rests upon and is supported by thein
after the retraction of the feeder. By cutting away the middle track, as shown,
and securing the yielding supports to the adjustable rear filling plates, I am
enabled to obtain a much greater adjustment for the width of the box or cover to.
be made than would be otherwise possible.
Each guide K is grooved longitudinally at its front end as at m to receive in it a
slide m' see Fig. 2, held in adjusted position in said groove by a screw m³, extended
through a slot m* in the guide, each of the said slides having attached thereto an
edge guide m³ extended vertically upward, as clearly shown in Figs. 2 and 3, the
lower ends thereof resting upon inturned ledges at the lower edges of the
guides K, the said edge guides m³ acting as stops to position the blank when
the latter is ready to be moved vertically by the former to be described, and is
clamped between the former and the follower, so that the blank will be raised in a
truly horizontal position. It will be noticed in Fig. 2, that the said stops extend
slightly above the horizontal plane occupied by the bottom of the follower D³
when the latter is in normal position. The projecting ledges n at the lower edges
of the guides K form a sort of track to keep the pasted portions of the blank from
contact with the plates 6º.
The bed plate A is cut away at the point where the pile of blanks is supported,
and has secured thereto the vat or pan H' which contains the water to be used for
wetting the blanks prior to feeding the same, and also encloses the wetting and
pasting devices. The wetting is effected along the dotted and full lines shown
in Fig. 36, Sheet 1, and along the full lines showing the bent over sides of the box.
The wetting devices or wetters shown in Fig. 4, Sheet 4, and Fig. 9, Sheet 7,
consist of a series of blocks e that are grooved or recessed at their upper ends to
receive sections of felt or other absorbent material e¹ to constitute the acting
surfaces of the wetters.
These blocks are recessed at their undersides, see dotted lines Fig. 9, to receive
loosely the preferably conical ends of bearings e² of skeleton holding frames e*,
supported in longitudinally recessed or grooved supports e and e¹. The grooved
supports e extend transversely of the machine and are each secured to a block et
adapted to slide horizontally in an undercut clamping groove e, formed in the top
of a standard e secured to a yoke e', shown only in Figs. 3 and 9, that is mounted
upon or fixed to a spindle extended up through a suitable stuffing-box e, see
Figs. 1 and 3, attached to the bottom of the vat H', the vertical movement of the
said spindle by or through the short link e10 connected to one arm ell of a rock-
shaft es, see Fig. 3, causing the wetters to be raised and lowered in the vat. The
rock-shaft is suitably supported in bearings on pedestals A³× and has rigidly
secured thereto a suitable roller or other stud F to enter and be actuated by the
cam surface F* of the cam F, shown separately in Fig. 31, Sheet 4, the rotation-of

page_text: which by shaft A* causes the wetters to rise at the proper time and moisten the
blank parallel to its front and rear edges along the lines upon which it is to be
hent. The grooved holding frames e¹s are disposed at right angles to the frames e
and are supported upon uprights 14 suitably secured to slides fadapted to be
longitudinally moved on the yoke e' towards or from the center of the machine,
the said slides forming the bases of spindles f¹ which are extended through suitable
stuffing-boxes in the bottoms of the paste pans H, to be described, lateral
adjustment of said paste pans and their entering spindles falso adjusting the
longitudinal wetters carried on the supports e, the slides f being held in adjusted
position on the yoke e' by set screws 500, see Fig. 9. Referring to Figs. 4 and 9,
it will be seen that inasmuch as the side tracks 61 are rigidly secured to the paste
pans, and the longitudinal or end wetters to the slides f, any lateral adjustment of
the said paste pans, and necessarily of their spindles, will also and simultaneously
adjust the side tracks 6' and the end wetters, so that they will always be
maintained parallel and the same distance apart, the one adjustment answering
for both. The inner sides of the end wetter holders e¹³ are slotted as at 15
see Fig. 3, and when a very long blank is used the transverse wetting
devices e, e¹ are extended, the outer ends of the endmost holding frames (*,
resting in the slots e while the inner ends of the said frames rest in and are
maintained upright by the lateral support es described, see Fig. 9. The slots
are of sufficient length to admit of considerable adjustment of the transverse
wetters, the lateral supports 8 of the latter being held in adjusted position, see
Fig. 9, Sheet 7, by the clamp el forming one side of the undercut groove e
formed in the top of the standard as best shown in Fig. 9, the said clamp being
moved by means of the screw 161. As best shown in Fig. 3, the transverse wetters
are independently adjustable and have independent supports or standards
therefor, said supports being secured to the yoke e' at the front and rear of the
spindle. A suitable hand-hole provided with a removable cover 20 is made in one
wall of the tank or vat H', whereby access to the lower part may be had, when
desired, see Fig. 3.
A horizontal web or flange h* is formed in the upper part of each corner of
the tank or vat H', see Figs. 4 and Fig. 10, Sheet 6, and the horizontally extende:I
slotted ears of the paste pan rest upon the said webs * as clearly shown ia
Fig. 10 to thereby sustain the paste pans in the vat, and the paste pans are
held in adjusted position by the set screws 6 extended through the slots in the
said ears and into the horizontal webs 4*.
The pasting devices are shown in Fig. 4, and Figs. 9 and 11, Sheet 7, a
portion of one of the paste pans H being broken away in Fig. 9, in order to
show better the internal arrangement, the pasters being shown as a series of
blocks f³, grooved at their upper edges and slotted or forked to embrace and
rest upon flexible tubular bearings fix preferably mounted upon the longitudinally
grooved upper sides of bars f which latter are notched on their lateral sides
to keep the blocks in position parallel with each other and to prevent them
from twisting upon the bars, the bars being rigidly attached at their ends to
cross bars In Fig. 4, I have shown the pasters as applied to all the bars
In practice, the said bars may be more or less filled up with these pasters,
according to the size and shape of the part of the blank to which it is desired
to apply the paste. For instance, alternate bars only may have pasters applied
thereto as when it is desired to apply paste to a blank on separated lines.
best shown in the detail Fig. 11, the bars f are yieldingly supported by
springs on the upper ends of which rest the cross bars, and the lower
ends of which bear on the bolder f, the latter being suitably recessed to
receive them, and the holder in turn being provided at its underside with a
hub or collar to receive the top of the spindle f¹ to which it is clamped by a
set screw extended through the collar to bear against the spindle. The
entire pasting device may be removed bodily from the paste pan by loosening
said set screw f8 and detaching the holder from the spindle. Inasmuch as the
B
As

page_text: pasters, are independent,, they may be applied to the bars fin such number
and position as to accommodate a blank of any desired shape, and to apply
the paste to, any desired portions thereof. In Fig. 4, the adjustable tracks b
overhang the pasting devices. In practice when the said tracks occupy the
positions in which they are shown in Fig. 4, the pasters which would be
immediately below the same are taken out. As has been stated, the spindles fl
are secured to the slides of carried by the yoke e' so that the pasters rise and fall
in unison therewith and with the wetting devices already described. When the
pasters rise with the wetters, they pass up through the paste in each paste pan H
and lift portions of the paste up against the blank above it, that is the blank at the
bottom of the pile of blanks, applying paste to the blank as at 75, Fig. 36. The
grooved tops of the blocks fretain in them more or less paste, depending upon
the depth of the grooves..
It
The wetters and the pasters thus operate on the blank to wet the same and
paste it at the proper places, and thereafter the actuating mechanism of the
feeder; G¹ moves the latter, forward as described, to engage, the wet and pasted
blank and carry it forward along the tracks into position above the former.
may be herein stated, that standards H2, Fig. 9, are secured to the bottom of the
tank H to support guide-ways H³ for the underside of the feeder in its recipro-
cations, the central track 6 being also supported by a cross-frame 30 secured to
the, guide-ways H'. Other guide ways H and H are provided at the rear and
front of the tank H' as shown in dotted lines Fig. 3.
The former over which the blank is bent to give shape to the box or cover to
be, made is composed of a rectangular casting N, Figs. 2 and 3, preferably of
hardened steel and of the exact size and shape of the interior of the box or
cover. The said former is adapted to rise and fall through an opening in the
bed-plate A of the machine of sufficient size to accommodate the largest former
to be used see Fig. 23, the effective opening for the passage of, the former being
adjusted and formed by the longitudinal side plates 6 and the filling plates d'
heretofore described, which, are adjusted to the size of the former to be. used.
Vertical guide ways; N₁, see Figs. 2, 3 and 5, are secured to the base of the
machine and to the bed plate A¹ to which cover plates N1x are attached, Fig. 5,
to receive and guide a reciprocating cross head T having rack bars T¹ secured
to or forming a part of the vertical sides thereof Figs. 3 and 5, to be engaged
by the toothed portions of like partly-toothed gears L, Figs. 1, 2, 3 and 5,
secured to a short shaft. L' supported in suitable bearings Lx on the guide
ways Nas best shown in Fig. 5. a small pinion L2, Fig. 1, being also secured
to the shaft L' and provided with teeth upon a portion of its periphery. An
armee Figs. 1 and 2, provided with rack teeth L' at its upper end and in
cgagement with the teeth on the pinion L' is shaped at its lower end to form
a slot L', see dotted lines Fig. 1, embracing the cam shaft A, and a roller or
other stud. L to be acted upon by a cam D shown detached in Fig. 29,
Sheet 7, is secured to the. arm L³, rotation of the said cam raising and lowering
the bar L³, and, by means of the teeth L' rotating the pinion I and thereby
5. the shaft L first in one and then in the other direction. As shown in Fig. 1
of the drawings, the bar L is at its lowermost position, and at rest, and it will
be seen that as said bar rises, it will rotate the shaft L' and the gears L
thereon in the direction of the arrow 100, Figs. 1 and 3, the toothed portion of
said gears at such time engaging the rack tooth T₁ of the cross head and raising
D. the latter, the upper end of which is secured to the underside of the former N
by a threaded bolt N extended through an opening in the horizontal face of
the former and secured by a set nut No. By the construction herein described
the former and cross-head are reciprocated vertically, the cross head moving in
rigid guide ways, so that no vibration thereof is possible, the rotary motion
5 given to the shaft L' being transformed into linear movement of the cross-head
by means of the gears Land rack teeth T' such mechanism ensuring a positive
powerful and steady reciprocation of the former.

ways
The toothed portions of the gears L and the pinion L³ are so arranged with
relation to each other that the former N completes its movement in either direction
simultaneously with the throw of the bar L³.
1.7.
The bed plate A¹ bas secured thereto standards D' to support the transverse
braces D of the head D', see Figs. 1, 2, 3 and 4, which sustains and guides the
follower, to be described, and also the co-operating parts which act to turn the
sides and ends of the blank over the former and the devices to thereafter compress
the same to form the cover or box.
Referring now to Figs. 2, 3, 4, and Figs. 16 and 17, Sheet 1, the follower D³ is
shown as detachably secured to the lower end of a slotted slide rod D extended
through a sleeve forming part of a fixed yoke-like portion of the head D³, and
a cylinder D is secured to the upper end of the slide rod D, said cylinder having
therein a piston D³, secured to a piston rod Do, which is extended within and
guided by the slotted slide rod D, and the piston rod is held in its normal position,
shown in Figs. 2 and 3, by a suitable spring-actuated latch 7 mounted upon the
sleeve D', see Fig. 2, the end of the latch. extending into a recess 200 in the lower
end of the piston rod, see Fig. 3. A small vent or opening 60 is made in the top
of the cylinder D8 through which air enters into or is discharged from the cylinder
above the piston. When the follower is raised, as will be described, the air
underneath the piston forms a cushion preventing sudden shocks, and the space
above the piston is filled with air, so that when the follower descends the air will
be slowly expelled through the vent 60 and the descent of the follower will be
cushioned thereby. In order at the air may pass from the under to the upper
side of the piston U have provided the latter with a small passage 65. The
weight of the follower D is increased, and its movement steadied by attaching a
heavy annular weight W to the cylinder D³.
The lower end of the slide rod D is reduced as at 1, Fig. 3, and Figs. 16 and 17,
Sheet 1 and provided with oppositely extended ears 1, while the follower has a
hub Dox formed upon its upper side, in the opening of which are two opposite
inwardly projecting ledges leaving the opening of the shape shown in Fig. 16 to
receive the end of the slide rod, which is inserted therein until the ears pass.
below the plane of the ledges 13 after which the follower is turned through an arc
of 90° thus bringing the ears / beneath the ledges and supporting the follower
thereby, the shoulder of the slide-rod De preventing the follower from being
displaced upwardly. The follower is normally held from any rotation upon the
slide-rod by the side wiper-plates i and end pressure-plates so to be described, as
shown best in Fig. 3. With the parts in the position in Fig. 3, the follower could
Bot be removed from the slide-rod, as it could not be rotated thereon; so, when it
becomes necessary to remove or replace a follower, the latch is withdrawn from
engagement with the recess 200 of the piston-rod, permitting it to drop, and
consequently allowing the slide rod to fall through the sleeve D' until the bottom
of the cylinder D³ rests upon the top of the sleeve. The follower is thus brought
below the lower edges of the side wiper and end pressure-plates, and it can be
rotated sufficiently upon the slide-rod to enable it to be removed therefrom. In
practice, the area of the follower will be slightly larger than the area of the former,
the difference being usually about one-thirty-second of an inch.
"
Side wiper-plates i, Fig. 3, which carry the lip-turners to be described, are
supported in an adjustable manner in the cross-braces D³ at the front and rear of
the follower, and are provided with shanks or extensions i rectangular in cross-
section and fitting in guide ways in the cross-braces D³, see Figs. 1, 3 and 4. Each
shank in practice is provided with a threaded hole in its outer end to receive the
threaded portions of an adjusting rod extended through suitable bearings in the
head in which the said rod may be rotated by a suitable hand-wheel 52, the rod
being restrained from longitudinal movement by a- slotted plate 50 fitting an

page_text: annular groove 51 in the shank of the corresponding rod. The extensions of the
side wiper-plates are of sufficient width, see dotted lines Fig. 4, to afford a firm
support for the said plates to maintain their inner acting faces in truly vertical
position and by means of the adjusting rods the said plates are adjusted toward
or from the path of the follower and former according to the thickness of the blank
to be acted upon, or the size of the former to be used.
A
Suitable brackets n, n' are secured to the outer faces of the side wiper-plates,
see Fig. 2, Figs. 19, 20 Sheet 8 and Fig. 21, Sheet 8, and are provided with
bearings n n for like rock shafts n² each having a longitudinal groove n³ therein,
the said bearings being located at the lower edges of the wiper-plates and at the
extremities of the rock-shafts, and they are at such a distance apart that the side
and lip turners, now to be described, inay be adjusted outwardly along the rock-
shafts to the extent required for the largest size of box or cover to be made on the
machine, the said shafts n being provided at one end with bevel gears n', as clearly
shown in Figs. 19, 20 and 21 to be engaged by like gears n° splined to and rotatable
with an actuating shaft n supported in bearings n in the brackets n'. The bevel
gears n' are moved longitudinally on the actuating shaft n when the side wiper
plates to which the brackets are attached are adjusted. The said gears 7 being
held between the bearings n' and the bevel gears n so as to cause gears nº to slide
along the shaft n when the side wiper plates are adjusted and, also being held
normally from longitudinal movement by said bearings and bevel gears.
pinion n is rigidly secured to the actuating shaft n and is engaged by a rack barn³,
see Figs. 2, 19, 20 and 21, upon the upper end of a link n10 jointed at its lower end
to a rocker arm n which is pivotally connected to the side frame n" and having
thereon a roller or other stud n Figs. 1, 2 and 5, adapted to enter and be actuated
by the cam groove C* on the gear C, shown separately in Fig. 27, Sheet 7, rotation
of the said gear C reciprocating the link n at the proper time and causing a
rotation of the actuating shaft n° first in one and then in the other direction, and
through the bevel gears n n causing rotation of the grooved shafts n² in opposite
directions. I have herein shown the side and lip-turners as adapted to act upon
the blank to first turn the side flanges 90 thereof, see Fig. 36, Sheet 1, down bodily
upon the vertical faces of the former, and to thereafter bend the lips or flaps 95 at
the ends of the said sides about the corners of the former and over upon the end
faces thereof and to hold the portions so bent in such position until the former in
its continued vertical movement has carried the bent blank grasped between the
former and follower, above and beyond the side and lip-turners, and against the
inner faces of the side wiper-plates i, hereinbefore described, which maintain
the sides of the box or cover against the former while the end pressure plates, to
be described, are moved forward to compress the pasted ends 77 of the blank upon
the corner flaps, as will be described, the ends 77 having been previously bent
down as hereinafter described. The side and lip turners are herein shown as
composed of plates or wings o and o¹, the former being provided with hubs o* loose
on the shafts 2 other hubз olx being splined by keys 300 to the shafts n² to rotate
therewith, each of said hubs ox having thereon a segment bevel gear o² to engage
a similar gear o³ on the end of a pintle o extending through suitable like ears o
on and pivotally connecting the adjacent pair of plates o and o', a set screw 12
extended through one of the ears o' of each wing o' bearing against the pintle and
thereby causing the said wings to move with the pintle when it is rotated on its
own axis. A spiral spring surrounds the pintle o, one end thereof pressing
against the plate o' and the other end thereof against the plate o, one end being
confined to said plate by a projection of the action of the spring normally
unfolding the plate o' as shown in Figs. 2, 3 19 and 21, and maintaining it in the
same plane with the plate o. Until the former has raised the blank against the
follower, the folding plates forming the side and lip turners are held normally in
unfolded or extended position, the shafts n occupying positions which cause said.
plates to occupy outwardly directed positions horizontally as shown in Figs. 2 and 3.

page_text: '
When the blank has been firmly clamped between the former and follower;-and-
hefore it is carried upward between the side wiper plates, the shafts'n' are rotated
in the direction of the arrows' Fig. 19, and the toothed hubs o¹* are turned-
therewith to positively swing the plates 'o and o still extended or unfolded, down
from the position shown in Figs. 2 and 3, into vertical planes parallel to the front
and reat faces of the former, thereby bending the projecting side flanges: 90 of the
blank over against the vertical sides of the former, the springs- being of sufficient
strength to maintain the plates o in unfolded-or open condition and cause each pair
of connected plates or wings o and o¹ to move as one in overcoming the resistance
offered by the blank to the bending of its sides. As soon, however, as the sides of
the blank are brought against the vertical faces of the former, further movement
of the plates or wings o is prevented thereby and as the shafts n² continue to
rotate, the geared hubs o* moving therewith and engaging the segment gears o
on the pintles of will rotate the said pintles in the ears of of the plates or wings o,
thereby turning the plates or wings of fixed to the pintles by the screws 12, into
the position shown in Fig. 20, at right angles to the plates or wings o, such
movement bending the lips or flaps 95 at the ends of the side flanges of the blank
sharply around the vertical corners of the former and pressing such bent lips or
corner flaps against the ends of the former. The compound side and lip turners
are held in adjusted position upon the shafts n² and restrained from longitudinal
movement thereon by clamp collars of which can be rigidly clamped upon the
shafts at the desired points, and as the said collars are located between the hubs ox
of the plates or wings o they prevent longitudinal movement of the side and lip
turners. The cam groove Cx by which reciprocation of the rack bar n is
controlled is of such shape that the side and lip turners are maintained folded and
closed upon the blank until the former has moved upward sufficiently to carry the
blank above them and into position to be held by the side wiper plates.
By the herein before described construction and operation of the side and
lip turners, the corners of the box or cover are sharply defined and positively.
made, and with much greater accuracy than would be otherwise possible while
rapid and extended adjustment for different sizes is readily secured.
The supports D' have suitable- bearings formed therein to receive and properly
hold four pressure screw shafts R, R1, R2 and R3, the 'said shafts extending across
the head and having secured thereto at their opposite ends similar gears 7 all of
which are engaged and partly rotated by reciprocating racks-R there being one at
each side of the machine in engagement with the pinions on the corresponding ends
of the said shafts, see Figs. 1, 2 and 4, each rack having a slot to receive a
guiding screw having its threaded end entered into the corresponding end of the
head D, see Fig. 22.
Each rack bar is provided with an extension cut away to embrace the can
shaft A and provided with a roller or stud Re to enter a groove B* in a cam B,
Fig. 2 and Fig. 28, Sheet 4, there being two such cams,-one at each end of the
shaft A the extensions being additionally guided by grooved bearing: rolls,
suitably secured to the side frames. The shafts R and R at the right hand side
of the machine viewing Fig. 1, are provided with right and left hand-threads,
see Fig 4, while at the left hand side of the machine, Fig. 1, the shafts-R³ R³ are
also provided with right and left hand screw threads, see Fig. 4, the same as the
shafts at the right hand side of the mathine.
A pressure head S, Figs. 1, 4 and 22 is supported upon the threaded portions of
the shafts at the right hand of the machine in Fig. 1, and a like pressure head S¹
is supported at the left hand side of the machine by the threaded portions of the
said shafts at that end thereof, each of said pressure heads having at each of its
ends two sleeve-like nuts S* Fig. 2, each of said nuts fitting the thread on one end
of one of the pressure shafts. The engagement of these nuts with the threads of
the shafts provides for moving the pressure heads S₁ positively backward and
forward along the pressure shafts by the rotation of the latter, the said pressure

page_text: heads being moved up against the partially made box.held between. them upon the
former, to. compress the pasted ends of the box upon the corner flaps previously
turned over as described.
Each nut S is mounted loosely in the pressure head so as to rotate therein, and
has attached to it a pinion or gear. S³ Figs. 2, and Fig. 24, Sheet 6, and each.
vertical pair of the pinions or gears S2 being engaged and rotated in unison by one
intermediate gear S³, Figs. 4 and 24, adapted to rotate on a stud S*, carried by
the pressure head. There are two intermediate gears S³ for each pressure-head,
and these gears mesh together, one intermediate gear of each pair having attached
thereto or arranged to rotate therewith a worm gear S, Fig. 24, which is engaged.
and adapted to be rotated by a worm on a vertical shaft Se having its bearings in
a part of the pressure head, said shaft Se being provided at its upper end with a
suitable handle S' by which it may be turned by hand when it is desired to adjust
plates
the pressure heads toward or from each other, to adapt the end wipers or
carried by them to the thickness of the blank, and also to the size of the particular
former to. be used.
With the pressure heads S,. S', properly adjusted to the size of the blank

box or cover and toward and from the former N, by the reciprocation of the
racks-R*.

The end wiper-plates are not rigidly held on the pressure heads, for if they were

withdrawn and the lugs 14 swung to one side to disengage the pivot s¹³ from the

upon the heads of the shanks and the inner ends of the sleev. The outer
ends of said shanks preferably are rounded as at $25 and are projected beyond
the heads of the sleeves by the force of the springs so as to bear against
the backs of the hearing blocks at opposite sides of the convex portion, so
that the end wiper plates 810 and attached blocks are free to rock slightly in the
pressure heads. to adapt themselves to any variation in the thickness of the ends of
the blank, longitudinal adjustment of the shanks being made by moving the
threaded sleeves in or out of the recesses as may be necessary. Inasmuch as the
headed shanks are held in the pressure blocks by the threaded sleeves, it will be
evident that the end pressure plates may be removed and replaced without
interfering at all therewith.

After the sides and corner flaps of the blank have been bent over about the
former N, as described, the former is raised and the ends -77 of the blank come in
contact with and are bent-down by the bottom of.the end, wiper plates, 10.

page_text: Referring now to Fig. 14, Sheet 7, and Fig. 4, Sheet 4; I have shown a piston G³
-secured to the feeder frame G adapted to enter an open-end cylinder G when
the feeding frame is retracted preparatory to engaging a blank to feed the
same, the piston G³ compressing the air in the cylinder G to thereby form a
cushion for the feeder and its frame, to obviate a shock at the end of its
rearward throw due to the momentum of the moving parts. The cylinder G
is suitably secured to the extended portion of the bed-plate A' as by bolts 40 and
the piston G³ may have any suitable packing applied thereto to make it tight in
the cylinder, while a suitable opening or openings will be made in the end of the
cylinder to permit the compressed air to pass slowly therethrough.
I have shown a modified form of supporting and cushioning mechanism for the
follower in Figs. 32 and 33, Sheet 3, wherein the cylindrical sleeve dix in the
head D is somewhat lengthened and heads t, t are secured to the top and bottom
thereof, having openings therethrough to admit a slide rod 2 to the lower end of
the rod the follower D³ is secured. A piston ³ is secured to said rod within the
cylindrical sleeve D the slide rod extending above the bearing and through
its head to receive thereon a stop collar to limit the extreme downward
movement or drop of the follower, said collar normally resting on the top of
a locking device, shown as a hub-like block pivoted to the head t, and.
normally held in the position shown by the spring . By moving the locking
block to one side, away from the path of the collar the latter will descend until it
rests upon the head t¹ of the sleeve D* thereby lowering the follower sufficiently
to permit it to be readily removed from the lower end of the slide rod 2. The
follower on its up-stroke is cushioned by a spiral spring t loosely encircling the
rod t, and supported by the piston t³, the said spring being compressed between
the piston and head t¹ when the follower is raised. In this modification the piston t³
may be made tight enough to compress the air between it and the heads t, tif
desired and thus secure an additional cushion.
In operation a series of blanks notched at their ends substantially as in Eig. 36,
are placed between the guides K with their front and rear edges against the gauge
or finger c and the gauges K respectively the lowermost blank of the pile of..
blanks resting upon the tracks 6, 6 and a portion of the auxiliary tracks 6, the
tracks being so arranged as to permit the wetters to pass up between them. The
drawings show the machine with the feeder as having passed over. a .sufficient
portion of its forward stroke to move the undermost blank of the pile forward.
underneath the parts c³, c¹³ of the presser foot, prior to completing the forward
stroke to position the blank upon the former and underneath the follower; but
prior to the beginning of the forward movement of the feeder the wetting devices
will have been raised to wet the underside of the blank along the dotted lines 20
shown in Fig. 36, and along the lines where the side flanges 90 are shown bent
up, thus slightly moistening the stock to prevent the same from cracking when
bent or folded. The pasters, as have been described, will also be lifted to apply
paste to the end flap of the box or cover, as shown at 75, in Fig. 36. The blank
having been wet and pasted, is moved forward by the feeder, under the gauge or
finger c and the presser foot c, c, the space below the finger being sufficient to
permit one blank to be so fed forward at a time, as has been described, the feeder
carrying the blank forward until its leading edge meets the vertical gauges.m³,
Fig. 3, before referred to, which act as stops for the blank, and correctly position
the latter. When the blank is thus positioned over the former N, the latter is
raised by the mechanism hereinbefore described, the said former carrying with it
the wetted and pasted blank to meet the underside of the follower D°, the
gauges m³ during such time acting against the end of the blank to keep the same
in position during its vertical movement, so that the blank is in the proper position
with relation to the former to be bent or folded in the desired lines. As soon as
the blank is brought up against the underside of the follower, the latter begins.to
rise, owing to the continued movement of the former, the blank being firmly
grasped between them. While the blank is thus clamped between the follower

page_text: and former, the upward movement is arrested and the side and lip turners, which
then stand at the level of the top of the former, are positively actuated, as described,.
to bend the side flanges of the blank over the front and rear vertical faces of the
former after which the plates o' bend the corner flaps or lips of the side flanges.
around the former and against its ends. Immediately thereafter and while the turners
are held in the last-named folded position, the upward movement of the former is
resumed, thereby carrying the bent blank upward into position between the side wiper
plates i, and the end wiper plates 10, the latter hending down the end flaps .77
upon the corner flaps 95 and when the blank is in proper position between the end
and side wiper plates, the racks R' actuate the shafts R, R1, R2 R as described:
to move the pressure heads S and S¹ toward each other and the former to press, as
described, the end wiper plates 10 against the ends of the blanks, forcing them.
tightly and smoothly against the corner lips or flaps to thereby set and hold the-
paste previously applied to the end lips or flaps, thus completing the box while, the
former remains stationary. The box or cover having been completed, by such
compression, the former descends, the racks R having been lowered to rotate the
shalis R, R, etc., in the opposite direction so as to withdraw the end wiper
plates so away from the end Haps of the box, so that the latter is free to descend
with the former, the follower following it in contact with the box until the stop-
latch entering the depression 200 in the piston rod D arrests its downward
movement and consequently limits that of the follower, thereby unclamping the
box or cover which moves down with the former until the down-turned edges of the
sides and ends of the box or cover come against the tops of the plates 6º and d³,
Fig. 23, which then act as clearers, stopping the descent of and stripping the box or
cover from the former which continues to descend until it is in its normal position
ready to receive the next blank to be fed. The box or cover thus stripped from
the former is left standing upon the said plates, and is now discharged from the
machine which is accomplished by an ejector w, shown in Figs. 2 and 5, striking
the box or cover and throwing it out at the delivery end of the machine, this being.
done at the same time that the feeder is acting to carry forward a wetted and
pasted blank.
The ejector w.is shown as a curved rod, carried by a vertical rock shaft w',.
Figs. 2 and 5, held in suitable bearings in the side of the machine and having at
its lower end an arm on which are mounted at opposite sides of the rock-shaft
suitable roller or other studs w² w in the path of movement of and to be acted
upon by in turn a cam lug w secured to the side of the cam F, see Figs. 2 and 5,
said cam lug acting to turn the rock-shaft quickly in its bearings and thereby
throw the ejector inwards to strike the box or cover a smart blow and throw it
from the machine, the return of the ejector into its normal inoperative position
being aided and quickened by a strong spring w coiled around the rock-shaft and
secured at one end thereto, the other end of the spring bearing against some fixed
part of the machine.
This invention is not restricted to the exact construction and arrangement of
parts as herein shown and described, as the same may be altered or modified without
departing from the spirit of my invention.
In the claims, the term "box" is also intended to include a cover, inasmuch as.
a cover is nothing more than a box with low sides and ends, and as will be evident
my herein described apparatus is equally applicable to the manufacture of either.
Having now particularly ascertained and described the nature of my said
invention, and in what manner the same is to be performed, as communicated
to me by my foreign correspondent, I declare that what I claim is :
1. A former upon which a blank is supported to be shaped, and compound lip
turners located adjacent the corners thereof, combined with actuating mechanism to
automatically move the lip turners bodily towards the former and thereby turn
projecting portions of a blank against some of the walls thereof, continued operation
of said mechanism turning a portion of each lip turner about the corners of: said.
