Figure 27 shows construction whereby the wedge is adjusted under the anvil in
horizontal section.
In these figures, like reference marks indicate corresponding parts in all
the views.
I is the base, and 2 the main frame. 3 is a shaft mounted transversely of the
main frame which carries the fly-wheel and clutch mechanism on one end, and
projects through the frame stopping even with the face of the guide 4, Figures 1
and 4, and carries a wrist-pin 5. The piston 6 slides vertically on the guide 4,
gibs 7 serving to hold same in place thereon. This piston 6 is rectangular in form
and has an extension 8, which will be presently described. On the lower end of
the piston as shown in Figures 2, 3 and 22, is a V-shaped groove 9, which for
affixing corner-strips to a square box would have its sides slope to a right angle to
each other. Grooves 10 best shown in Figure 22, and adapted to grasp the edges
of a strip are formed in the sides of the groove 9 and extend its entire length.
The lower back corner of extension 8 is rounded as shown in Figures 1 and 3, and
extending along the edge thereof is a shallow channel 11 as wide as the strip to be
affixed to the box corner in which one of said strips may lie, and be forced forward.
Narrow strips 12 of thin metal are laid upon the remaining portion of the edge so
as to overhang the channel 11 and form a guide preventing displacement of the
strip, which will be understood on reference to Figure 8. These strips 12 extend as
shown in Figures 21 and 22 along the under side of the piston 6, overhanging
there what is virtually an extension of the channel 11 coextensively with the
groove 9, and so forming the aforesaid grooves 10. Thus it is seen that a strip
inserted in the upper end of the groove in the extension 8, may be passed around
and into the grooves 10 in the piston. As shown in Figure 1 a triangular hole is
cut through the piston 6 so as to register with the end of the shaft 3, and into this
projects the wrist 5 on said shaft, the pitman 13 being pivoted on said wrist and
extending to the lower angle of the triangular hole which is rounded to receive it
and there being pivotally secured to the piston. The anvil 14 consists of a block
of iron seated on a ledge on the side of the frame 2, and carrying on its upper side
near its front end flat inclined faces 15 at an angle to each other equal to that of
the slides of the groove 9 of the piston. If desired a bar of hard steel 16 may
be inserted at the apex for better wearing properties. A plate 17, conforming
on its top edge to the angle of the faces 15 of the anvil is secured to the end.
of the anvil to serve as a guide for holding the box on said anvil, the bottom
of the box being pressed against the face of the said plate whereby the edges of
the sides of the box which are to be joined and stayed are held parallel along
the apex of the anvil. The lower edge of this plate 17 is rounded to facilitate
turning the box upon as large a plate as can be used. The vertical and
horizontal diameter of the plate being the same, and several plates of different
sizes and interchangeable being provided it is obvious that a plate of the greatest
area of face may be obtained for each size of box and better results be thereby
secured. Vertical adjustment of the anvil 14 to provide for various thicknesses
of box-material is provided for in the use of a wedge 18 which is inserted upon
the correspondingly inclined ledge of the frame 2 hereinbefore mentioned, and so
lies between said ledge and the under side of the anvil, longitudinal movement of
said wedge obviously raising and lowering the anvil. This movement of the
wedge is conveniently obtained in the construction shown in Figure 27, in which
figure the back edge of the wedge is shown bent at right-angles and bifurcated.
A stud 18 is set in the franc, parallel to the wedge, so that it lies within the
said bifurcation, and a thumb-nut 18 screwed thereon, which has a neck engaging
the bifurcated end of the arm 18. This anvil is held in place by a strap 19
which lies upon same, having its ends fitted over studs 20 set in the frame 2 above
and below the said anvil, and held firmly pressed against the said anvil by means
of band-wheels 21 screw-threaded onto said studs and bearing on the outer side of
i
:

page_text: the said strap 19. In order to resist the downward thrust of the piston upon the
front end of the anvil, a hook-bolt 22 is set in a hole through the frame behind and
near the back-end of the anvil, its hook bearing upon the top of the anvil, and a
wheel 23 being screw-threaded upon its lower end whereby it is drawn forcibly
forward.
As shown in Figures 1, 20, 21 and 22 presser-plates 24 are pivoted by their
arms 25 on screws 26 in each edge of the piston 6, said plates projecting below the
face of the piston and a sufficient distance to press the paper firmly against the
faces of the anvil before the piston brings the strip to be affixed into contact there-
with, and may be if desired slightly rounded so that, as they contact with the box
sides and press downwardly, moving outwardly thereon, they will press the box
sides firmly against the anvil at the proper relative position to each other and have
no tendency to dislocate or abrade the said box sides. In the construction shown
in Figure 22 these plates are pressed normally against the sides of the piston by
means of a bow-spring 27 operating to diverge the arms 28 projecting upwardly
from one end of each plate. A saw-cut or slot 29, Figures 3, 5 and 6 is made
cross-wise of the groove 11 on the back edge of the extension 8 of the piston and
near said slot with its lower face on a level therewith is a lug 30, which has, in
passing, another lug 31 on its upper end, the use of which will hereinafter be
described. A screw 32 is set in the under side of the lower end of the lug 30, and
the stationary jaw 33 of the shear is placed upon said screw being perforated for
that purpose, and extends into the slot 29, a set-screw 36 serving to secure its free
end and a set-screw 37 bearing against its back edge serving to adjust the blade
and hold it in its adjustment, the hole through which the screw 36 passes being
slotted to allow a movement when said screw 36 is loosened. The movable. blade 38
(also shown in Figure 13) is also pivotally mounted on the screw 32; an excentric
bushing 41 intervening whereby said shear is adjusted, and enters the recess 29
below the blade 33 as best shown in Figure 6. The said blade 38 is extended on.
the side of the screw 32 opposite the cutting end of said blade to form an arm,
wherein is set a stud 39 which is, in the construction shown, bifurcated in its lower
end, and provided with a pin 40 for a purpose hereinafter more fully set forth.
The bottom of the channel 11 as shown in Figure 6 and by broken lines in Figure 5,
is rounded as shown at 34 so as to prevent the shear blade from bending the end
of the strip, with a short bend near the cut. Mounted in the lug 31 is a stud 42
which carries thereon, a gear 43, so as to revolve freely and which is provided in.
the construction shown in Figures 6 and 7 with a long hub 44 which is exteriorly
screw-threaded with a "left-hand " thread of fine pitch. A nut 45 is first screwed
on said hub after which the dentated feed-wheel 46 (further shown in Figures 9 and
10) is screwed thereon, the said nut 45 serving to hold the wheel 46 in any set
position on the said hub. This construction has particular merit in view of the
adjustment of the wheel 46 which is required, said wheel being the feed-wheel,
into the interdental spaces of which the spurs of the metal corner-strips enter in
being fed along the strip-way 11 and between the shears to be cut off. Owing to
the fact that it is desirable to cut the strip between the spurs thereof, the feed-
wheel 46 has circumferential adjustment on the hub 44 and owing to the fineness of
the thread thereon the said adjustment may be made without appreciable lateral
adjustment of the wheel 46. In said strip-way, back of the wheel 46 as shown in
Figures 9 and 10 is a recess 47, having ledges 48 at its ends whereon rest the ends
of a spring-plate 49, so set as to form a depressible bearing for the metal corner-
strip as it passes under the feed-wheel 46, whereby in case of the said strip sticking
in the channel 11 for any cause, said strip will be depressed by the feed-wheel into
the recess 47 against the action of the spring-plate 49 which will allow the feed-
wheel 46 to revolve in contact with the points of the spurs on the metal corner-strip
without feeding said strip or subjecting the feed-mechanism to unnecessary strain..
The mechanism for intermittently revolving the said feed-wheel and stopping same.
at the right place will be now set forth. Mounted in the piston 6 concentrally with
the curvature of the lower back corner thereof, is the shaft 50 to which is secured.

page_text: the segment. 51, as shown in Figures 1, 14,and:15 which revolves freely on said shaft
and has.on its peripheral..surface..teeth, . as shown in.the, first-named: figure. A
pitman 52 is connected with one of the arms of this segment: by. means of a wrist-
pin. 54. set: in.the end of the wrist-pin. 5 on the shaft.3. The said wrist-pin 54 is
set in the end of the said wrist-pin slightly ahead of the centre thereof, so that the
segment will be caused to partially revolve with its shaft: upwardly a sufficient
distance to clear the feed-pawl hereinafter described from the anvil before the piston
shall descend sufficiently to catch the same.. Just inside the teeth on the segment is
a semi-circular series of holes 55,. there being one of said holes near each tooth of
the segment except a few at the top, where they are unnecessary..
The second row
of holes 56 are screw-threaded, and are situated in the inner edge of the segment.
A strap 57 is slotted in one end as shown in Figures 11 and 12 and a thumb-screw 58
is inserted therein, which is adapted. to secure the said strap to the segment by
being screwed into one of the holes 56, said strap carrying a roller 59,on.a pin on
its other extremity, a leader 60 on the end of said pin entering one-of the smaller
holes 55 ensuring stability and, exactitude of adjustment. Three or more adjust-
ments of the roller 59 may be made without. moving the screw 58 to another
hole 56. Secured to the upper end of the segment 51 is a bracket 61, .which
carries on its end' a pin 62, and a roller. 63. The rollers 59 and 63 are merely
abutments, and it is.not necessary that they be rollers, although it is preferable.
Reference being had to Figures 1, 5, 6 and 7 it will be seen that. mounted loosely
on the end of the stud 42 is a lever 64, on: the distal extremity of said lever is
journalled a pinion 65, which meshes-with. the gear 43 on.said stud. On. the upper
end of this lever 64 is an arm 66. adapted to engage the roller 63, as shown in
Figures 1, 2, 3 and 5, and by said engagement to depress.that end of the lever 64
slightly, moving it from the position shown in Figure 5 towards the position shown
in Figure 1. On the downwardly projecting end of the lever 64 is a block. 67
provided with a face 68, a face 69.inclined.thereto, and stops.70 and 71. Fastened
on.the.stud 42 so as to have adjustment pivotally thereon is an.arm 72, which is
curved so as to bring its end parallel. to .the. said. stud. A bell crank lever 73 is
pivoted on the end of said arm and extends so as to contact with the roller 59
on the upward movement of the segment when the said lever is in the position
shown in Figure 1 said contact throwing the lever into the position shown in
Figure 5, a lug 74.thereon engaging a tooth of the gear 43. On the upper side
of the opposite end of the lever 73.and in a position thereon correlatively opposite
the block: 67 is a block 75 provided with an inclined face 76, a face 77, and stop.
surfaces 78 and 79. In the end of the lever 73 is a pin 80 and. in, the side.of.the
lever 64 is a pin 181, a. pulling-string 82 being connected, at each end, to the free
end of said pin and acting to draw them. toward. each other.
The reasons. for this somewhat, complicated construction will be seen on a
description hereinafter of the operation of the device..
Secured to the end of the.shaft. 50 is.a disc 84, which has thereon. a wrist pin 85,
and revolves with the shaft. As.shown in Figures: 14 and 15, the said disc and the
hub of the segment 51 on the same shaft is engaged by means of a spring-pressed
pin 86, which is set in the said hub, and projects into an oblong recess 87 in, the
disc, its end being pointed and entering conical depressions in each end of the said
recess 87, by means of which a slight movement of the disc independently of the
hub of the segment is allowed. As shown in Figures 1, 16, and 17 a guide is
formed in the lower end of the segment 51 radially thereof and through this passes
the stem 88 of the feed pawl, said pawl being formed of a strip of steel bent.
inwardly as shown in Figure 17 and backwardly as shown in Figure 16, having on
its extremity an upturned lip.89, as shown in both these figures, which days across
the channel 11 in such a position that it will when elevated, enter between two
opposite pairs of spurs on the tin-strip next below the shear, and as the segment
descends after the piece of tin is cut from the strip, will carry the piece so cut off
downwardly through the groove 11 and so deliver it to the groove in the under end
of the piston 6. The stem 88 of the feed pawl is connected by a pitman 90 to the

page_text: wrist pin 85 of the disc 84, and it is hence obvious that the movement allowed
the feed-pawl
by the construction shown in Figures 14 and 15 will cause
to engage and disengage the tin strip. It is necessary to cause this engagement at
the same moment the shear works and the segment starts down, and to cause the
disengagement just before the time the said segment begins its upward movement.
On the opposite end of the shaft 50 and made integrally therewith in the
construction shown in Figures 3, 18 and 18 is a wheel 91 which is provided with
a cam projection 92 having a curved face, while slightly above the cam a stud
projects from the side of said wheel 91 and carries. a roller 93. A plate 95 shown
in the figure just named and also in Figure 19, is secured to the side of the frame
in such a manner that the tappets 96 and 97 will be contacted with by, and act upon
the projection 92 and the roller 93 at the proper time in the movement of the piston,
the wheel 91 being carried upon and moving with the piston while the plate 95 is
stationary on the frame. The pitman 98 is connected, with the wheel 91 by means
of a pin 99, its distal extremity being provided. with an. open-sided slot 100 which is
hooked over and engages the pin 40 in the stud 39 Figures 6 and 18. By means
of the slot the shear is opened and closed at the extremes of the reciprocating
movement of the pitman 98 and in removing from the machine the moving shear-
blade 38 a slight twist thereof will detach it from the said pitman, by pressing the
pin 40 out of the open side of the slot.
102.
As shown in Figures 1, 23, 24, and 25,.an upright 101. is secured to the back
upper corner of the piston. (extension 8) in such a manner as to leave the groove 11
open between the said upright and piston, and a groove 102 is milled in the face,
which groove is so formed and situated as to guide the strip by one row of its spurs,
along the upright 101 and into the groove 11, a presser-plate 103 being hinged to
the said bar so as to press upon the strip and keep it in its place in the groove
A spring 104 acts to keep the said plate pressed into place. This presser-plate
also serves to hold two lengths of strip together after being hooked, as will be
understood upon a description, hereinafter of the operation of the device. The
free edge of the plate 103 may be curved backward if desired as shown in
Figure 25, thereby rendering easier the operation of swinging the said plate slightly
back to enable the operator to hook on a new strip the strip slipping freely under
the plate in inserting. The upper end of the upright 101 is curved backwardly as .
A lever 107
shown at 105 and a bell 106 is carried on the upper extremity thereof.
is pivoted thereon as shown in Figure 24 its end being turned back forming an
aim 108 to which is secured a clapper 109 the arm and clapper being so formed and
extended as to bring the latter close to the bell. A spring 110 acts to draw the
lever in such a direction as to cause the bell to be struck by the clapper, namely,
in the direction shown by the arrow a Figure 24. The object of this bell is to
sound an alarm as soon as the upper end of the strip enters between the upright 101
and the presser plate 103. The construction necessary to complete this function is
as follows; An arm 112 is formed on the lever 107 and has a backwardly extending
lip 113 turned thereon. When the strip is in the position shown by broken lines
in Figure 24 this lip 113 rests against its edge, the engagement of the spurs on the
strip with the groove 102 preventing a displacement of the strip thereby. As soon
as the strip is drawn downwardly by the feed-wheel until the upper end of the strip
is below the said lip 113 the tractile spring 110, having its fixed end fastened to the
upright 101 above the pivotal point of the lines 107, will cause a movement of the
lever to sound the alarm. In order that there shall be no strain edgewise on
the strip which could possibly cause a displacement thereof under any conditions
and to hold the lip 113 out of constant engagement therewith, an upward projec-
tion 114 may be provided if desired on the lever 107 opposite the lip 113, and bear
upon the opposite edge of the tin-strip.
A finger 111 on the upper corner of the part 105 of the upright 101 serves as a
bearing point for the strip opposite the arm 114 and acts also to prevent the strip
becoming disengaged from the said arm upon the sudden downward movement of
the piston in operating. The strip now has two opposite bearing points above the

page_text: lip 113 and the lever 107 is by the bearing of the arm 114 on the edge of the strip,
held in such a position that the lip does not touch the strip until same is drawn
below said arm 114 when the lever moves slightly and brings the lip against the
said strip from which position it trips the lever 107 as soon as the strip descends a
.sufficient distance.
The piston stops at midstroke in its downward movement and hence starts at the
same point, the shaft making a single complete revolution. To stop the movement
of the operative parts of the machine at the completion of each operation, the
shaft 3 should be provided with any form of clutch that will engage the revolving
element of fly wheel and cause said shaft to make one complete revolution,
and stop.
The operation of this device is as follows: The device is in its normal position
as shown in Figure 1. A strip of tin bearing spurs suitable for affixing is placed
between the projection 114 and the lip 113 of the bell-lever 107, and pressed under
the free edge of the spring pressed plate 103 until the spurs register with the
groove 102, when the plate closes, pressing said spurs into the groove.
The strip
is then manually drawn downwardly until its lower end enters the groove 11 and
passes downwardly through same to the feed-wheel 46, after which one revolution
of the main shaft of the machine, will, as hereinafter specified cause the said feed-
wheel to force the strip down to and slightly through the shear, and cause said
shear to cut off the projecting piece which is the only waste occurring at any time
during the operation of the machine, unless from accident it shall be necessary to
insert another strip to form the initial one of a connected series. The strips are fed
continuously to the machine by allowing the strip to be fed downward as it is used
until the bell rings, which occurs as herein before mentioned as soon as the upper
end of the strip has passed the projection 113 and hence is between the bar 101 and
the hinged plate 103. The operator then takes a new strip and places same on the
bell-lever as just described above, and enters same in the above-described manner
between the upright and hinged plate drawing it downward therebetween and
hooking the first or first and second pair of spurs of the new strip into the holes
left in punching the first or first and second spurs of the strip previously inserted.
The presser-plate 103 will obviously hold the said strips thus engaged until they
enter the groove 11 when it will, of course, be impossible for them to disengage,
and their operation both in feeding and being affixed to the box-corner is precisely
the same as a continuous strip the length of both. Strips may thus be successively
inserted and connected and their entire length is utilized, leaving no waste of metal
which is an item of considerable importance.
The machine is now in its normal position and is charged with a strip ready to
be fed downward. The anvil 14 is moved on its seat until it projects under the
piston from its back side just the depth of the box to which the strip is to be
affixed, and, by means of the wedge 18 the said anvil is raised or lowered to accom-
modate the thickness of the board used in the box. The number of spurs which a
strip should have which would be of a length sufficient for the depth of the box is
then determined, and the strap 57 is so set that the leader 60 will enter a hole in
the series 55, which is a proper number in the series. These adjustments being
made, the machine is then started by throwing in a suitable clutch whereby
connection is made between the fly-wheel which has been previously set revolving
and the shaft 3, starting said shaft to revolve in the direction of the arrow thereon
in Figure 1. This movement of the shaft starts the piston descending, and through
the pitman starts the segment upward on its partially rotary movement.
The cam 91
is in a position normally which is shown in Figure 184, and on the movement of
the segment revolves in the direction of the arrow c thereon. The descent of this
piston, and the revolution of the segment and cam 91 brings the projection 92
into contact with the tapper 96, which causes a movement of the shaft 50 to
the limit of the slot 87, Figure 15, independently of the movement of the segment,
and in the direction of the arrow d, Figure 1, which causes the feed
pawl 89 to move downwardly as in disengaging from between the spurs of a strip,

page_text: were one of said strips at this point of the operation is in the die on the under
end of the piston. As the segment 51 ascends, it actuates the gear 65, said gear-
having been previously thrown into engagement therewith, which will be herein--
after described, and through it drives the feed-wheel 46, by means of the gear 43,
said feed-wheel revolving in the direction of the arrow e Figure 1, and drives the
strip downward through the groove 11 and the shears, and continues so to do until
the roller 59 on the strap 57 comes into contact with the end of the arm 73, which
partially revolves said lever in the direction of the arrow f Figure 1, releasing the
engagement between the blocks 67 and 75 and inserting the block 74 between two-
teeth of the gear 43 whereby the revolution of the gear 43 and the feed-wheel is
instantly stopped allowing the spring 82 to swing the arm 64 on the stud 42-
which swings the axis of the gear 65 in a direction from the segment and causes-
the said gear 65 to travel upon the teeth of the gear 43 and so be revolved in the
same direction as previously shown and thus be drawn out of mesh with the teeth.
of the segment, rolling as it is drawn out. In this manner the piece of tin has
been fed down so as to project below the shears a sufficient distance to fit the-
box-corner, and it now remains for the mechanism to cut same off and feed it into.
the grooves on the lower end of the piston 6. The piston 6 then reaches its limit
of depression applying the pressure, and commencing its ascent, the upward
movement of the segment 51 continuing, and hence the revolution of the cam-wheel,
continuing in the direction of the arrow e Figure 18 until when the piston reaches
the position shown in Figure 1, the wrist-pin 5 being diametrically opposite the
position shown in said figure and the segment having reached its point of
ultimate elevation relative to the piston, the cam-wheel 91 is in the position shown
in Figure 18, as is, also, the pitman 98, the shear being ready to close, the
feed-pawl being directly under the shear and ready to engage between the spurs
of the strip as before stated said strip being in position to be cut and engaged.
The wrist-pin 5 is, at this time, approaching and passing the dead-centre relative
to and distal from the pin 53 of the segment, and hence the segment is, practically
at a stand-still, and the shaft 50 is moving upward in the direction of the arrow c¹
in Figure 18. Owing to this motion the roller 93 is brought into forcible and
operative contact with the tappet 97 which partially revolves the cam-wheel 91
in the direction of the arrow c Figure 18 imparting thereto a very quick motion
to the limit of the slot 87 which partially revolves the disc in the direction
opposite the arrow d Figure 1 thereby quickly pulling the lip 89 on the feed-
pawl 88 between the pair of spurs of the strip next below the shear, thereby
engaging same, and simultaneously closing the shear, thereby severing the strip.
The segment 51 now starts downward carrying the section of the strips so cut off
downwardly through the groove 11 carrying it to the grooves in the lower end
of the piston 6 and into a position to be affixed. During the time the segment
continues downwardly carrying the strip the shears stand closed on account of
the lost motion due to the slot 10 in the pitman 98, but during the latter part of
such movement the shear is partially opened by the end of the slot 100 coming:
into contact with the pin 40 of the shear, and the opening is completed by the
action of the cam wheel and tappet which disengages the feed-pawl in which open
position it remains until again closed, as hereinbefore specified. Just before the
segment reaches its downward movement the roller 63, Figure 1 is brought into.

in the position shown in Figure 5 at this time, as they were left by the operation.
previously described, the feed-wheel 46 being at rest, and engaging spurs of the
strip to be fed. This engagement of the roller 63 and arm 66 moves the lever 64
on the pivot 42 in the direction of the arrow Figure 5 a sufficient distance to
bring into operation the two inclined faces 69 and 76 of the blocks 67 and 75.
respectively, and at that time the spring 82 acting through the arm 80 moves the
lever 73 in a direction opposite the arrow f Figure 1, which causes the said
inclined faces to move upon each other and continue the movement of the lever 64
just mentioned until the gear 65 shall be meshed with the teeth of the segment..

page_text: During this time the block 74; has been engaged with the teeth of the gear 43
holding same from 'revolving, whereby a planetary movement has been imparted to
the gear 65 causing it to roll into engagement with the teeth of the segment.
As soon as this engagement is completed the block 74 has been withdrawn from
the teeth of the gear 43 and hence same is ready to be revolved and perform the
operation of feeding the strip and being released from engagement with the segment,
both of which have been described. The stops 70 and 71 and the stop surfaces 78
and 79 co-operate to limit the movement of the lever 72 in obedience to the action
of the spring 82; and may obviously be so constructed and placed as to subserve
this purpose in any desired way. The parts are now in position to repeat the
operation from 'the beginning.
The operation of affixing the strip as far as it relates to the operation of those
parts and not heretofore described is as follows: The strip of tin has been by
the mechanism inserted in the piston as herein before set up. The operator then
places the box in position the bottom resting on the plate 17 and held thereon by
his thumbs, pressing the fore-finger of each hand upon the sides to be joined and
bringing the same against the faces 15 of the anvil, causing the edges thereof that
are to be joined to lie approximately parallel along the apex of the anvil. The
piston descending first sets the sides in position by bringing the rounded edges
of the presser-plates 24 into contact therewith and then affixes the strip in the
usual manner by pressure.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
