Improvements in Machines for Use in the Manufacture of Paper
and like Boxes.
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 to be as follows:-
My invention relates to machines for securing the joints in the manufacture of
boxes of paper, strawboard or other similar material; and more particularly to a
machine constructed for applying a single stay or fastening strip of suitable
material over the joint, at a point both outside and inside of the corner, which is
caused to adhere to the parts by paste or other suitable adhesive material.
My invention consists in the construction, arrangement and combination of parts
forming a machine for applying stay or fastening strips upon box corners in the
manner above referred to, as will hereinafter be described in detail.
A machine embodying my invention embraces as its main features, clamping dies
for pressing stay-strips in contact with the margins of the corners or parts to be
joined and secured; means for guiding between the clamping dies and lengthwise
over the corner of the inserted box, the strip from which the individual stay-strips
are severed; means for severing the individual stay-strips from the continuous
strip and of greater length than fed forward for location on the outer corner of the
box, to form a loose or projecting end beyond the inner edge of the latter, and
means directing and carrying such loose or projecting portion of the stay-strip
beneath or against the inner corners of the box.
The machine herein shown also embraces other further and additional improve.
ments than above referred to, all of which will hereinafter be described in
detail.

device, to be hereinafter referred to.
To explain in detail, the main frame of the machine is formed with a horizon-
tally arranged bed-plate A and two vertical parts or standards a and a' upon which
the several parts forming the machine are supported.
B is a non-reciprocating die.or anvil-block arranged horizontally with one end
projecting the front of the frame, which projecting end forms the working surface
of the die or anvil upon which the box or blank is placed and supported to be
operated upon as shown in Fig. 3. This die or anvil-block, which, in the present
instance shown, is formed with flat working faces b b upon its upper side arranged
at right angles to each other as shown, is supported within seats or bearings
located in studs all and a projecting from the bed-plate of the frame, in a manner
to be movable longitudinally whereby its projecting end may be moved a greater or
less distance from the face of the frame to be adjusted for boxes of different depths
as will be described.
The anvil-block. as herein illustrated, is provided with a central longitudinal
groove or recess for the support and operation of a reciprocating die as will
bereinafter be described, which said groove, for convenience in construction and
assembling of the parts, extends to the front end of the anvil-block, and a block b'
having oblique faces coinciding with the working face of the anvil-block, is
removably fitted into the said groove 63 at the front end thereof, and forms part of
the anvil-block or die in operation. Such block may however be formed integral
with the anvil-block.
The anvil-block, as herein illustrated, is arranged to be adjusted longitudinally
in its bearings and set in a desired position by means of a shaft d which is mounted
to turn or rotate in suitable bearings in studs d' and d² on the bed-plate of the
frame, and is provided with a pinion d³ thereon which meshes with a rack d' on the
under side of the anvil-block to form connection with the latter. This shaft d
as herein illustrated, is constructed for the detachable connection therewith of a
key d as a convenient means by which it may be operated, and is also arranged to
be locked from movement to hold the anvil block in a stationary position by incans

page_text: of a clamping arm d on the stud d'. Any suitable meaus other than above
described may, however, be employed for adjusting the position of the anvil-block
without departing from the spirit of my invention..
d', Fig. 1, is a yoke which engages with the anvil-block in seats de formed upon
opposite sides thereof as shown in Fig. 4, and is provided with a threaded stem d
having connection with the bed-plate of the supporting frame by means of a nut d¹º,
in order to hold the anvil-block from vertical movement and prevent its tipping
forward when pressure is brought to bear upon its front end in operation.
C is a reciprocating die for operating in combination with the non-reciprocating
die B to form the clamping or pressing device and is formed with a notch or
recess c, Fig. 7, in its under surface forming a working face to co-act with the
face bb of the die B. The die C is seated in a vertically sliding frame or carrier c¹
which is mounted in suitable ways upon the face of the standard a and may be
operated by any suitable means, the same being operated in the present instance
shown, from a rotating driving shaft a³ mounted in bearings in the standards a and a',
through the medium of a crank-pin a carried at the end thereof, and a link a con-
necting said crank-pin with a pin c² on a part of the slide as will be described.
The movable die C is supported to co-act with the non-reciprocating die B with
a yielding or elastic pressure to conform to material or stock of varied thickness
and also prevent jar or breakage to any of the connecting parts, such movement or
action being secured as follows,-A block es is seated within an opening in the
slide c of somewhat greater length than the block to have a longitudinal movement
therein, and is connected with a rod or stem c which is loosely seated in said slide
with one end having a screw-threaded connection with the block 3 and its opposite
end projecting the upper end of the slide. This stem has a flange or collar c
thereon, which in the instance shown, is located at a point within an opening in the
slide, against which one end of a spring 7, having its opposite end bearing against
the slide c', acts to hold the block towards the upper end of its seat or opening e
in a position as shown in Fig. 7, and cause the slide with its die C to co-act with
the stationary die B with a yielding pressure as described, when the block c³ is
carried or forced downward by its operating means, such means as herein shown
being the connecting link a' and its driving mechanism.
The tension of the spring e' may be regulated to adjust the pressure of the upper
die more or less as required to properly fasten the stay-strip, by turning the stem c
to adjust the position of the flange or collar thereon in its relation to the opposing
bearing surface of the spring on the frame. The stem is held stationary in. its
relation to the connecting block by a set-screw c³.
E is a vertically movable part or plunger arranged to operate at the rear of the
die C and is formed with a cutting edge e at its rear side to act in conjunction with
a stationary cutter F to sever the stay-strip at the proper point from the continuous
strip fed to the machine. Said plunger is attached to a slide e' which is mounted in
a suitable guide in the standard a, and as herein illustrated, is arranged at its upper
end to engage with a cam a on the driving shaft a³, by which it is operated to act
in combination with the several other co-acting parts for securing the stay-strip on
the blank, as will hereinafter be more fully set forth. The slide e¹ is provided with
an anti-friction roll e² supported thereon for engagement with its operating cam,
and is held in operative contact with the latter by means of a spring ³ which, as
shown in the drawings, is supported on a pin or bolt et attached to the rear side of
the slide, with one end having a bearing on the frame at e as shown in Fig. 2.
Any suitable mechanism for operating the plunger E other than as above described
may be employed without departing from the spirit of my invention.
The stationary cutter F, shown in detail in Fig. 17, is supported by a plate Fl
in a position above the line of the stationary die B and is formed with an opening f
for the passage of the stay-strip, the lower wall of which opening at its forward
edge f, forms the cutting edge with which the movable cutter E co-acts. The
plate F is shown removably attached to the standard a and is provided, as shown
in Figs. 15 and 16 with ribs f* f2 on its face, between which the said stationary

page_text: cutter F is supported with its face in line with the rear surface of the plunger E,
and said plate is also provided with plates 133 secured on the ribs ff having
under cut sides at their inner edges forming guide-ways f*f* in which the projecting
sides of the plunger extend and move to guide the latter.
Said stationary cutter, see Figs. 3, 15 and 25, is movably supported on the
plate F by means of a pin f projecting therefrom and is rendered adjustable in
its relation to the movable cutter by means of pins f, fo, which are loosely
supported in the plate F' with one end projecting the latter in contact with the
cutter F at or near the line of its cutting edge and their opposite end in position
for engagement with an adjusting plate secured on the outer face of the plate F¹
by means of an adjusting-screw 8. By means of this adjusting plate the said pins
may be moved to adjust the cutter F in its relation to the reciprocating cutter to
insure proper co-operation therewith and also take-up for wear of the engaging
parts. In operation, the upper end of the cutter F tilts slightly backward on the
pins ff, when the movable cutter is above the latter, thus allowing free and easy
movement of said movable cutter, and is moved or tilted forward in close contact
with the movable cutter as the latter moves over said bearing pins and the cutting
edges co-act with each other.
f³, as more clearly shown in Fig. 15, represents a projection on the face of the
plate F¹, termed the "stripper," which projects within the opening in the stationary
cutter plate over its cutting edge and is formed with a V-shaped depression in its
lower edge slightly above the edge of the cutter, to engage with and prevent the
end of the continuous strip from being drawn upward from position over the cutting.
edge, on the return upward throw of the movable cutter.
The non-reciprocating die B is adjusted to support the box thereon with its inner
edge in a line with the front face of the plunger E as shown in Fig. 3, and the
latter having its cutting edge at the rear side thereof as described, severs the stay
or jointing strips from the continuous strip, of a length equal to the width of the
plunger, greater than the length fed between the clamping dies for location on the
outer margin of the box sides, which additional length projects beyond the inner
edge of the box, and is forced below the inner edge of the box by the continued
downward movement of the plunger E, which latter for this purpose is termed the
tucker," into a position to be engaged by a horizontally moving plunger or die G,
termed the "turn-in" device, and carried inside the box to be pressed against its
inner margins by the pressure of the movable die C as will hereinafter be
described.
G is a horizontally movable plate, which like the plunger G is supported to slide
in the anvil-block B and formed with a working face corresponding with the die B
as shown.
"
The plate g, in the present instance and as more clearly shown in Figs. 3 and 5,
is attached at one end of a rod g¹ which extends loosely through the plunger G
with its rear end in contact with an adjustable stop g to hold said plate 9 in its
normal position just forward of the path of the tucker E, and in a position to
support or hold up the inner edge of the box, as shown in Fig. 3, in order to prevent
its being turned or bent down below the line of the "turn-in device by the
tucker E on its downward movement to bend or tuck down the loose end of the
stay-strip as before described. This plate ġ is also operated to remain stationary
or nearly so to support the end of the box, until the "turn-in "G has moved forward
in close proximity thereto and serve as a guide to insure the free and unobstructed
entrance of said "turn-in" beneath the corners of the box. Such movement or
operation of the plate g is secured by a spring g' having its opposing bearings on
the "turn-in" G and on a collar or flange 9 on the rod g' as shown in Fig. 5, which
expands and serves to hold the rod g₁ stationary, or nearly so, while the "turn-in
is being moved forward in close position to said plate 9 as described, at which time,
a second and lighter spring 93 located between the plate g and "turn-in" G or
connecting bearings, is sufficiently compressed to move the plate g forward with the
"turn-in.' This spring 93 also serves as a cushion against which the "turn-iu "
"

page_text: acts when the plate 9 comes in contact with the stationary block or die B, and
serves to prevent any undue jar or breakage of parts.
1
The vertically movable plate 64 at the forward end of the stationary die is yieldingly
held or supported by a spring in a normal position with its upper edge slightly
above the working faces of said stationary die, in order to hold the box corner or
sides above the latter and the line of the faces of the "turn-in" G, to insure the
free passage of the plunger beneath the sides of said box, and is also adapted to
act in conjunction with the upper die C to support the box, and hold the severed
stay-strip in position thereon to prevent its being drawn forward and into the box
when its loose end is carried therein by the "turn-in " G, as follows,
1
The upper die C is arranged to have a certain amount of lost motion in relation
to its connecting driving link a through the medium of the elongated opening in
the latter at its point of connection with the pin or stud on the vertical slide
carrying said die C, whereby the latter, when it first contacts with the end of the
projecting plate or with the sides of the interposed box and the stay-strip thereon,
may only engage therewith with a pressure equal to its own weight and not sufficient
to lower said projecting plate, to hold the box and stay-strip in position while the
tucker E descends to press down the loose or projecting end of the latter and the
"turn-in" G moves forward to carry said end against the inner margins of the box.
At this time the lost motion between the upper movable die and its connecting link
is taken up and the pressure brought to bear upon the former so that it may co-act
with the faces of the lower die and the "turn-in" G, which latter is within the
box at this time, to clamp or press the stay-strip upon the opposite margins of
the box.
The tucker E on its down stroke only moves across the edge of the box a distance
equal to the thickness of the latter, (which is sufficient to turn the loose end of the
stay-strip down the proper distance), and not below the line of the faces of the
"turn-in" device, thus preventing any liability of being struck by the latter in its
forward movement. The tucker E is also provided with a centrally arranged
groove or notch e in its forward face and at the lower edge thereof, which is
arranged at an angle as more clearly shown in Figs. 3 and 23, and is adapted to
take-up or receive the rib formed at the center or apex of the loose or projecting
end of the stay-strip when the sides of the same are turned downward and
necessarily toward each other by reason of their oblique position, as clearly shown
in Fig. 24; and the "turn-in" G is also provided with a centrally arranged curved
guide groove g in its front face which is adapted to receive the end of the rib i¹
taken up by the notch in the tucker and guide or turn the same under the box
corner with the sides of the stay-strip. By this construction for handling the rib
formed at the center of the loose end of the stay-strip when the same is turned
down and carried beneath the box-corner, the said end is located smoothly against
the inner margins of the box, and all liability of breaking or wrinkling the paper,
as would occur if not thus provided for, is obviated.
The "turn-in" device G and connecting parts may be operated by any suitable
means to act in unison with the several co-acting parts in the operation of securing.
the stay-strip upon box-corners as described, the means as herein shown, consisting
of a lever H which is pivoted at one end upon the supporting frame at hand at its
opposite end connects with an arm or part 9 of the plunger G, said lever being
provided with an anti-friction roll h¹ secured thereto which is held in operative
contact with a cam a' on the driving shaft, from which the lever is operated, by a
spring 2.
The continuous strip of paper or other material to be fed to the machine for
staying box-corners is carried upon a reel I which is supported by an arm I¹
attached to the machine.
The stay-strip after leaving the reel is first passed through a folder J which acts
upon the strip to double and fold the same at its center, so that it will take and
maintain a V-shape to conform to the box-corner when it is fed over the latter
between the clamping dies.

page_text: K is a pasting roller, the periphery of which is made V-shape to fit within the
creased lower surface of the strip, and K' is a presser-roll for holding the strip in
contact with the said pasting roll.
L is a scraper located forward of the pasting roller, through which the
strip passes to have the superfluous glue or other adhesive material removed
therefrom.
.
The strip is fed forward over a suitable guide M to the clamping dies, after
leaving the device L, by a suitable feeding device which operates to give an
intermittent forward movement of the strip whereby the end of the latter is fed
forward between the clamping dies and over the margin of the box sides located
on the stationary die, and remains immovable while the jointing strip to be attached
to the box is being severed from the continuous strip and secured upon the outer
and inner margins of the box-corner in a manner as described.
A device or mechanism of any suitable construction may be employed for thus
feeding and guiding the stay-strip; a simple and convenient means as herein
illustrated, consisting of a reciprocating gripping device which operates to engage
and carry forward the paper strip in its forward movement and becomes released
from the strip at the limit of its forward throw, so as to move backwardly without
producing any corresponding movement in the strip, the several parts of such
gripping device and the means for guiding the strip to the same and from said
feeding device to the clamping dies, being as follows,―
M Fig. 1, is a guide-plate upon which the main operative parts of the feeding
device are supported, provided with a vertical flange M' at one side thereof having
a longitudinal guide-slot m in which the gripping and carrying device is held and
guided. The said gripping device comprises a sliding plate m arranged vertically
against the flange M', and held in place by means of a plate or piece m², located at
the opposite or exterior face of said flange M¹ and connected with the plate m¹
through the guide-slot m as more clearly shown in Fig. 26.
7113 is the lower jaw of the gripping device, the same being arranged centrally
beneath the path of the stay-strip and provided with a sharp or narrow bearing-
edge m' to engage the inner surface of the strip in the center or crease of the same.
This jaw m³ is connected with and operated by the sliding-plate m².
m is the upper or movable jaw of the gripping device, which is arranged above
the lower jaw and made vertically movable, so that it may be either engaged with
or lifted free from the lower jaw. Said movable jaw is mounted upon a pivot-
pin m projecting from the sliding plate m¹ in a position to overhang the path of
the stay-strip.
As herein illustrated, the sliding plate m' and the gripping jaws carried thereby,
are driven by operating mechanism engaging with the movable jaw me alone, such
mechanism, in the present instance shown, consisting of a pivoted lever m³ which
is operated by a cam or eccentric m³ on the driving shaft a³ and connected with an
arm or part m10 of the gripper jaw me through the medium of a connecting
hink Said lever mis held in operative contact with the cam m³ by a
„spring m¹²
The gripping device being thus operated, I provide frictional engagement
between the sliding plate m' and its guide-plate, tending to retard the movement of
the plate, so that when pressure is applied to the upper end of the gripper-jaw min
a direction to carry the said upper end of the arm forward, the gripper-jaw will
first be depressed, after which a continued forward pressure upon the end of its
arm will carry the sliding plate and gripping jaws bodily forward. Likewise when
the pressure is applied to the arm of the movable jaw me to move the same
backwardly, the jaws will first be opened and the entire gripping device be then
moved bodily backward. Any suitable means may be employed for producing
such frictional engagement between the sliding plate m¹ and its guide-plate. The
means employed as herein shown, see Fig. 27, comprises a flat spring m¹ which
bears at its center against the plate m, and two screws or pins m which extend
losely through said plate m² and have screw-threaded engagement with the

page_text: plate m, whereby the spring may be caused to hold the plates m' and 'm² in contact.
with the opposite sides of the plate M¹ with more or less pressure as may be
desired.
In applying the jointing-strips upon the corner of boxes of different sizes it is.
desirable that the distance to which the strip is fed forward past the cutting or
severing device at each advance movement of the feeding device, should be capable
of variation in order that the length of the strip used upon the box may correspond
with the depth of the same. In connection with the stationary die or anvil-block,
which is adjustable to afford a greater or less distance between the end of the same
and the cutting mechanism as hereinbefore described, I have provided a connecting
mechanism between such movable anvil-block and the feeding device actuating
mechanism, whereby the movement of the block a certain distance will produce a
corresponding change in the throw of the gripping-jaws, whereby the length of the
strip fed at each reciprocation of the feeding jaws will correspond with the length
of the exposed part of the anvil-block and the joint to be made.
The means as herein illustrated for securing such connection, consists of a lever o
which is pivoted upon the frame at o' with one end connecting with the anvil-
block to be moved thereby, and its opposite end extending in a position to be
engaged by the feed operating lever or part thereof at the limit of its backward
throw and form a stop for the same. By this arrangement of parts, when the
auvil-block is moved outwardly, the upper end of the lever o is thrown backward
and allows a correspondingly greater backward throw to the feed operating lever m³-
and consequently a greater movement to the gripping-jaw. When, on the
contrary, the anvil-block is moved inwardly, the upper end of the lever o is thrown
forward and limits the throw of the feed lever m accordingly to decrease the
distance at which the stay-strip is fed forward at each action of the feeding
device.
An adjusting-serew 2 is supported by the lever m8 with one end in position to
be engaged by the lever o and forms an adjusting medium between said parts,
whereby the throw of the feeding device may have an adjustment independent
of the automatic adjustmeut secured by its connection with the anvil-block as
described, in order to be regulated for any desired length of stay-strip regardless.
of the depth of the box being operated upon, and also to take up for wear of
the parts.
A further adjustment of the feeding device is secured by locating an adjusting-
screw m¹³ in an arm or extension m14 of the sliding plate m', at a point to engage.
the arm of the movable gripping-jaw m' and regulate the vertical or upward
movement of its working face or end to conform to stay-strips of different
thickness. By such adjustment of the movable gripping-jaw
may also be made
to bite or engage the strip sooner or later at the beginning of its forward
movement and consequently regulate the length of strip fed forward, as will be
readily understood.
Any suitable means may be employed for guiding the stay-strip from the
scraper L to the gripping-jaws and from the latter to the clamping dies, a simple
and convenient construction for such purpose as herein illustrated, consisting of a
longitudinal guide-bar p which is arranged in line with the center of the stay-strip,,.
and with its upper and guiding surface in approximately the same horizontal plane
as the working face of the lower gripping-jaw m³ and in position to engage the
under surface of the stay-strip at a point within the seam or crease thereof. This.
guide-strip, which is supported at each end upon the guide-plate M in the position
described, serves to guide the strip and hold the same in proper position with
relation to the gripping jaws, to prevent an undue bending or twisting of the strip.
when the same is engaged by and between the said jaws..
The folder J, through which the stay-strip is, passed to be folded and take a
V-shape as and for the purpose herein before described, consists of two vertically
arranged plates or jaws j, j, between which the stay-strip is passed to be creased,
which are supported upon a stationary plate ;¹ in a manner to be adjusted in. their

page_text: relation to each other according to the thickness of the material forming the
stay-strip and also for the purpose of producing a crease of more or less sharpness
as may be required in material of different. kinds. Each of said creasing jaws, as
more clearly shown in Fig. 11, are carried by plates 22, which are arranged to
slide on the plate j¹ and are provided with lugs 3 3 on their under side having
screw-threaded openings therein to receive a threaded stem by means of which
the creasing jaws are adjusted. This said stem is centrally mounted to turn or
rotate in a suitable bearing in a lug on the under side of the supporting plate j',
and is formed with a right and left hand screw-thread at opposite sides of its
bearing for engaging with the lugs whereby the creasing jaws may be
moved to and from each other by a single operating stem as described. The
latter is provided with a knob as a convenient means by which it may be
operated.
8
The plate is provided with an upturned flange at one end thereof having a
guide-opening through which the strip is entered, and with side walls:
arranged at some distance apart at their rear end, so as to gradually bring together
the margins of the strip and guide the same in a folded position between the
creasing jaws j j.
is
The folder J, see Fig. 1, is supported on a vertically adjustable holder or
support whereby it may be adjusted, according to the width of stay-strip being
used, so as to bring the upper edge of the folded stay-strip in line with the top of
the paste-wheel and secure a uniform line of travel for the same. Said holder
supported on a stud j¹ on the bed-plate H and is adjustable thereon in the present
instance shown, by means of an elongated opening located therein and a set-
screw which engages with said holder and extends through the opening thereiu
into engagement with the stud j¹¹.
A guide-plate is adjustably supported in a position above the guiding walls 18 js
at the rear of the creasing jaws jj, in order to engage the upper edge or fold of the
stay-strip and hold both lower edges against the plate to insure the folding of
the strip at its center as it is passed between the jaws jj. Said guide-plate is
supported in a vertically movable position on a threaded post 10 located on the
plate j, and is held in contact with an adjusting-screw to be moved vertically,
either up or down therewith, by means of a spring ". Such adjustment of
the guide-plate is necessary to move the same for different widths of stay-strip
employed.
The presser-roll K' supported above the paste roll K, is carried by an arm
extending from a block or collar k, which latter is supported on a post or standard k¹
in a manner to rotate and be vertically movable thereon, whereby the roll may be
adjusted to bear with more or less pressure on the pasting roll according to the
thickness of the stay-strip, and also be removable from its position over said pasting
roll to allow for the ready placing of the stay-strip thereon when the latter is first
placed on or through the several parts from the roll, preparatory to using the
machine. The presser-roll is held in yielding contact with the pasting roll to be
self-adjusting to material of different thickness and also to any irregularities in the
same, by means of a spring k² which is supported on the post k with one end having
a bearing against the block k and its opposite end bearing against an adjusting-
screw located on said post, the latter being threaded part way of its length for
the operation of said adjusting-screw. The tension of said spring upon the block k
to cause the presser-roll to bear with more or less pressure upon the pasting roll,
is regulated by the adjusting-screw as will be obvious.
The presser-roll is movably locked from rotary movement in a horizontal plane,
by means of a pin on the post k which is adapted to be received in a slot or
opening located in the lower edge of the block or collar k, as more clearly shewn
in Fig. 13. In order to move the presser-roll from above the paste-roll, the
collark is simply raised from connection with said pin k and is then free to
be turned as desired.
S, Figs. 1 and 13, is a scraper adapted for removing the superfluous adhesive

page_text: material from the paste-wheel before reaching the stay-strip and regulate the
quantity to be placed on the latter.
The scraper L, herein before referred to, is more particularly adapted to spread
the adhesive material uniformly upon the stay-strip after passing over the paste-
roll and also remove the superfluous material therefrom. This device consists of
two plates and which are supported, one above the other, on a post or rod 12
projecting from the tank or receptacle 13, and are formed to present a V-shaped
opening between their adjacent faces to receive the stay-strip which is fed to the
same in such form. One of said plates is adjustable in its relation to the other in
order to vary the space between the same for different thickness of stay-strip, by
means of an adjusting-screw 4, which, in the present instance shown, is supported
in a vertically stationary position on an arm of the post with its threaded end
in engagement with an arm or part 1 of the plate l', to move the latter vertically
and adjust the same.
i
The adjacent edges of the plates and are constructed to be movable, one past
the other, in a manner as clearly shown in Fig. 14, which represents a vertical
section through said plates, whereby they may be regulated to remove or less of the
adhesive material from the stay-strip without liability of tearing or otherwise:
damaging the latter, as might be caused if the strip engaging surfaces were arrange
to move in the same line to or from each other and thereby be liable to pinch or bite
said strip between the same.
The scraper L, as herein shown, is detachably supported on a tank 1, its
supporting post being seated within a suitable socket or seat at one side of said
tank, as it is obvious that when a previously prepared gummed strip is used, such
scraper is not necessary and therefore it is desirable to have the same removable
from the path of said strip.
The machine herein shown is arranged to be operated by power, the same being
provided with a belt-wheel R on the driving shaft, although it is obvious that
the same may be arranged to be actuated by a foot-lever or other convenient
means.
Having thus set forth my invention and illustrated the same in one practical
form, it will be obvious that the machine shown may be more or less modified as
to the various details of construction and arrangement of the parts, and
certain features be entirely omitted, without departing from the spirit of my
invention.

forming a machine for applying stay or fastening strips upon box corners in the
manner above referred to, as will hereinafter be described in detail.
A machine embodying my invention embraces as its main features, clamping dies
for pressing stay-strips in contact with the margins of the corners or parts to be
joined and secured; means for guiding between the clamping dies and lengthwise
over the corner of the inserted box, the strip from which the individual stay-strips
are severed; means for severing the individual stay-strips from the continuous strip
and of greater length than fed forward for location on the outer corner of the box,
to form a loose or projecting end beyond the inner edge of the latter, and means
directing and carrying such loose or projecting portion of the stay-strip beneath or
against the inner corners of the box."
The machine herein shown also embraces other further and additional improve-
ments than above referred to, all of which will hereinafter be described in detail.

page_text: Figure 26, is a sectional view through line 26-26 of Figure 1, and
Figure 27, is a detail plan view of some of the parts forming the paper feeding-
device, to be hereinafter referred to.
To explain in detail, the main frame of the machine is formed with a horizontally
arranged bed-plate A and two vertical parts or standards a and a¹ upon which the
several parts forming the machine are supported.
B is a non-reciprocating die or anvil-block arranged horizontally with one end
projecting in front of the frame, which projecting end forms the working surface of
the die or anvil upon which the box or blank is placed and supported to be operated
upon as shown in Figure 3. This die or anvil-block, which, in the present instance
shown, is formed with flat working faces bb upon its upper side arranged at right
angles to each other as shown, is supported within seats or bearings located in
studs a and a projecting from the bed-plate of the frame, in a manner to be
movable longitudinally whereby its projecting end may be moved a greater or less
distance from the face of the frame to be adjusted for boxes of different depths as
will be described.
The anvil-block, as herein illustrated, is provided with a central longitudinal
groove or recess 63 for the support and operation of a reciprocating die as will here-
inafter be described, which said groove, for convenience in construction and
assembling of the parts, extends to the front end of the anvil-block, and a block b
having oblique faces coinciding with the working face of the anvil-block, is
removably fitted into the said groove 63 at the front end thereof, and forms part of
the anvil-block or die in operation. Such block may however be formed integral
with the anvil-block.
The anvil-block, as herein illustrated, is arranged to be adjusted longitudinally
in its bearings and set in a desired position by means of a shaft d which is mounted
to turn or rotate in suitable bearings in studs and d² on the bed-plate of the
frame, and is provided with a pinion d³ thereon which meshes with a rack on
the under side of the anvil-block to form connection with the latter. This
shaft d as herein illustrated, is constructed for the detachable connection therewith
of a key d as a convenient means by which it may be operated, and is also
arranged to be locked from movement to hold the anvil-block in a stationary
position by means of a clamping arm d³ on the stud d'. Any suitable means other
than above described may, however, be employed for adjusting the position of the
anvil-block without departing from the spirit of my invention.
d', Figure 1, is a yoke which engages with the anvil-block in seats de formed
upon opposite sides thereof as shown in Figure 4, and is provided with a threaded
stem d having connection with the bed-plate of the supporting frame by means of
a nut, in order to hold the anvil-block from vertical movement and prevent
its tipping forward when pressure is brought to bear upon its front end in
operation.
C is a reciprocating die for operating in combination with the non-reciprocating
die B to form the clamping or pressing device and is formed with a notch or
recess c, Figure 7, in its under surface forming a working face to co-act with the
face bb of the die B. The die C is seated in a vertically sliding frame or
carrier c¹ which is mounted in suitable ways upon the face of the standard a and
may be operated by any suitable means, the same being operated in the present
instance shown, from a rotating driving shaft a³ mounted in bearings in the
standards a and a¹, through the medium of a crank-pin a¹ carried at the end
thereof, and a link a³ connecting said crank-pin with a pin c² on a part of the
slide as will be described.
The movable die C is supported to co-act with the non-reciprocating die B with
a yielding or elastic pressure to conform to material or stock of varied thickness
and also prevent jar or breakage to any of the connecting parts, such movement
or action being secured as follows, a block c³ is seated within an opening cª in the
slide c of somewhat greater length than the block to have a longitudinal movement
therein, and is connected with a rod or stem c³ which is loosely seated in said
•

page_text: slide with one end having a screw-threaded connection with the block and its
opposite end projecting the upper end of the slide. This stem has a flange or
collar thereon, which in the instance shown is located at a point within an
opening in the slide, against which one end of a spring c', having its opposite end
bearing against the slide c', acts to hold the block e towards the upper end of its
seat or opening in a position as shown in Figure 7, and cause the slide with its
die C to co-act with the stationary die B with a yielding pressure as described,
when the block 3 is carried or forced downward by its operating means, such
means as herein shown being the connecting link a' and its driving mechanism.
The tension of the spring may be regulated to adjust the pressure of the upper die
more or less as required to properly fasten the stay-strip, by turning the stem co to
adjust the position of the flange or collar thereon in its relation to the opposing
bearing surface of the spring on the frame. The stem is held stationary in its
relation to the counecting block by a set-screw c³.
E is a vertically movable part or plunger arranged to operate at the rear of the
die C and is formed with a cutting edge e at it rear side to act in conjunction
with a stationary cutter F to sever the stay-strip at the proper point from the
continuous strip fed to the machine. Said plunger is attached to a slide e¹ which
is mounted in a suitable guide in the standard a, and as herein illustrated, is
arranged at its upper end to engage with a cam as on the driving shaft a³, by which
it is operated to act in combination with the several other co-acting parts for
securing the stay-strip on the blank, as will hereinafter be more fully set forth.
The slide el is provided with an anti friction roll & supported thereon for engage-
ment with its operating cam, and is held in operative contact with the latter by
means of a spring which, as shown in the drawings, is supported on a pin or
bolt attached to the rear side of the slide, with one eud having a bearing on the
frame at e as shown in Figure 2. Any suitable mechanism for operating the
plunger E other than as above described may be employed without departing from
the spirit of my invention.
The stationary cutter F, shown in detail in Figure 17, is supported by a plate F
in a position above the line of the stationary die B and is formed with an opening ƒ
for the passage of the stay-strip, the lower wall of which opening at its forward
edge, forms the cutting edge with which the movable cutter E co-acts. The
plate F is shown removably attached to the standard a and is provided, as shown
in Figures 15 and 16 with ribs ff on its face, between which the said stationary
cutter F is supported with its face in line with the rear surface of the plunger E,
and said plate F¹ is also provided with plates f³f secured on the ribs ff having
under cut sides at their inner edges forming guide-ways ff in which the
projecting sides of the plunger extend and move to guide the latter.
Said stationary cutter, see Figures 3, 15 and 25, is movably supported on the
plate F¹ by means of a pin f projecting therefrom and is rendered adjustable in
its relation to the movable cutter by means of pins f6, f, which are loosely
supported in the plate F1 with one end projecting the latter in contact with the
cutter F at or near the line of its cutting edge and their opposite end in position for
engagement with an adjusting plate f7 secured on the outer face of the plate F
by means of an adjusting-screw f8. By means of this adjusting plate the said pins
may be moved to adjust the cutter F in its relation to the reciprocating cutter to
insure proper co-operation there with and also take-up for wear of the engaging
parts. In operation, the upper end of the cutter F tilts slightly backward on the
pins ff, when the movable cutter is above the latter, thus allowing free and
easy movement of said movable cutter, and is moved or tilted forward in close
contact with the movable cutter as the latter moves over said bearing pins and
the cutting edges co-act with each other.
f", as more clearly shown in Figure 15, represents a projection on the face of
the plate F¹, termed the "stripper," which projects within the opening in the
stationary cutter plate over its cutting edge and is formed with a V-shaped
depression in its lower edge slightly above, the edge of the cutter, to engage with

page_text: and prevent the end of the continuous strip from being drawn upward from position
over the cutting edge, on the return upward throw of the movable cutter.
The non-reciprocating die B is adjusted to support the box thereon with its
inner edge in a line with the front face of the plunger E as shown in Figure 3,
and the latter having its cutting edge at the rear side thereof as described, severs
the stay or jointing strips from the continuous strip, of a length equal to the
width of the plunger, greater than the length fed between the clamping dies for
location on the outer margin of the box sides, which additional length projects
beyond the inner edge of the box, and is forced below the inner edge of the box
by the continued downward movement of the plunger E, which latter for this
purpose is termed the "tucker," into a position to be engaged by a horizontally
moving plunger or die G, termed the "turn-in" device, and carried inside the
box to be pressed against its inner margins by the pressure of the movable die C
as will hereinafter be described.
g is a horizontally movable plate, which like the plunger G is supported to
slide in the anvil-block B and formed with a working face corresponding with the
die C as shown.
""
The plate g, in the present instance and as more clearly shown in Figures 3
and 5, is attached at one end of a rod g' which extends loosely through the
plunger G with its rear end in contact with an adjustable stop 9' to hold said
plate g in its normal position just forward of the path of the tucker E, and in a
position to support or hold up the inner edge of the box, as shown in Figure 3, in
order to prevent its being. turned or bent down below the line of the "turn-in
device by the tucker E on its downward movement to bend or tuck down the loose
end of the stay-strip as before described. This plate g is also operated to remain
stationary or nearly so to support the end of the box, until the "turn-in" G has
moved forward in close proximity thereto and serve as a guide to ensure the free
and unobstructed entrance of said "turn-in" beneath the corners of the box. Such
movement or operation of the plate g is secured by a spring 9 having its opposing
bearings on the "turn-in" G and on a collar or flange 9 on the rod g¹ as shown in
Figure 5, which expands and serves to hold the rod g¹ stationary, or nearly so,
while the "turn-in" is being moved forward in close position to said plate gas
described, at which time, a second and lighter spring g³ located between the plate g
and "turn-in" G or connecting bearings, is sufficiently compressed to move the
plate 9 forward with the "turn-in." This spring g also serves as a cushion
against which the "turn-in" acts when the plate 9 comes in contact with the
stationary block or die B, and serves to prevent any undue jar or breakage of
parts.
The vertically movable plate 64 at the forward end of the stationary die is
yieldingly held or supported by a spring in a normal position with its upper edge
slightly above the working faces of said stationary die, in order to hold the box
corner or sides above the latter and the line of the faces of the "turn-in" G, to
insure the free passage of the plunger beneath the sides of said box, and is also
adapted to act in conjunction with the upper die C to support the box, and hold¹
the severed stay-strip in position thereon to prevent its being drawn forward
and into the box when its loose end is carried therein by the "turn-in" G, as
follows,
The upper die C is arranged to have a certain amount of lost motion in relation
to its connecting driving link a through the medium of the elongated opening in
the latter at its point of connection with the pin or stud on the vertical slide
carrying said die C, whereby the latter, when it first contacts with the end of the
projecting plate or with the sides of the interposed box and the stay-strip
thereon, may only engage therewith with a pressure equal to its own weight and
not sufficient to lower said projecting plate, to hold the box and stay-strip in
position while the tucker E descends to press down the loose or projecting end of
the latter and the "turn-in "G.moves forward to carry said end against the inner

page_text: margins of the box. At this time the lost motion between the upper movable die
and its connecting link is taken up and the pressure brought to bear upon the
former so that it may co-act with the faces of the lower die and the "turn-in" G,
which latter is within the box at this time, to clamp or press the stay-strip upon
the opposite margins of the box.
65
The tucker E on its down stroke only moves across the edge of the box a
distance equal to the thickness of the latter, (which is sufficient to turn the loose
end of the stay-strip down the proper distance), and not below the line of the faces
of the turn-iu" device, thus preventing any liability of being struck by the latter
in its forward movement. The tucker E is also provided with a centrally arranged
groove or notch e in its forward face and at the lower edge thereof, which is
arranged at an angle as more clearly shown in Figures 3 and 23, and is adapted to
take-up or receive the rib formed at the centre or apex of the loose or projecting
end of the stay-strip when the sides of the same are turned downward and
necessarily toward each other by reason of their oblique position, as clearly shown
in Figure 24; and the "turn-in "G is also provided with a centrally arranged
curved guide groove 9' in its front face which is adapted to receive the end of the
rib taken up by the notch in the tucker and guide or turn the same under the
box corner with the sides of the stay-strip. By this construction for handling
the rib formed at the centre of the loose end of the stay-strip when the same is
turned down and carried beneath the box-corner, the said end is located smoothly
against the inner margins of the box, and all liability of breaking or wrinkling the
paper, as would occur if not thus provided for, is obviated.
The "turn-in" device G and connecting parts may be operated by any suitable
means to act in unison with the several coacting parts in the operation of
securing the stay-strip upon box-corners as described, the means as herein shown,
consisting of a lever H which is pivoted at one end upon the supporting frame at h
and at its opposite end connects with an arm or part g of the plunger &, said lever
being provided with an anti-friction roll secured thereto which is held in
operative contact with a cam a² on the driving shaft, from which the lever is
operated, by a spring h².
The continuous strip of paper or other material to be fed to the machine for
staying box-corners is carried upon a reel I which is supported by an arm I¹
attached to the machine.
The stay-strip after leaving the reel is first passed through a folder J which acts
upon the strip to double and fold the same at its centre, so that it will take and
maintain a V-shape to conform to the box-corner when it is fed over the latter
between the clamping dies.
K is a pasting roller, the periphery of which is made V-shape to fit within the
creased lower surface of the strip, and K' is a presser-roll for holding the strip in
contact with the said pasting roll.
L is a scraper located forward of the pasting roller, through which the
strip passes to have the superfluous glue or other adhesive material removed
therefrom.
The strip is fed forward over a suitable guide M to the clamping dies, after
leaving the device L, by a suitable feeding device which operates to give an
intermittent forward movement of the strip whereby the end of the latter is fed
forward between the clamping dies and over the margin of the box sides located on
the stationary die, and remains immovable while the jointing strip to be attached to
the box is being severed from the continuous strip and secured upon the outer and
inner margins of the box-corner in a manner as described.
A device or mechanism of any suitable construction may be employed for thus
feeding and guiding the stay-strip i; a simple and convenient means as herein
illustrated, consisting of a reciprocating gripping device which operates to engage
and carry forward the paper strip in its forward movement and becomes released
from the strip at the limit of its forward throw, so as to move backwardly without

page_text: producing any corresponding movement in the strip, the several parts of such
gripping device and the means for guiding the strip to the same and from said
feeding device to the clamping dies, being as follows,
M, Figure 1, is a guide-plate upon which the main operative parts of the feeding
device are supported, provided with a vertical flange M¹ at one side thereof having
a longitudinal guide-slot m in which the gripping and carrying device is held and
guided. The said gripping device comprises a sliding plate m¹ arranged vertically
against the flange M', and held in place by means of a plate or piece m², located at
the opposite or exterior face of said flange M¹ and connected with the plate m
through the guide-slot m as more clearly shown in Figure 26.
m³ is the lower jaw of the gripping device, the same being arranged centrally
beneath the path of the stay-strip and provided with a sharp or narrow bearing-
edge in to engage the inner surface of the strip in the centre or crease of the same.
This jaw m³ is connected with and operated by the sliding plate m¹.
m is the upper or movable jaw of the gripping device, which is arranged above
the lower jaw and made vertically movable, so that it may be either engaged
with or lifted free from the lower jaw. Said movable jaw is mounted upon a
pivot-pin m² projecting from the sliding plate m¹ in a position to overhang the path
of the stay-strip.
As herein illustrated, the sliding plate m' and the gripping jaws carried thereby,
are driven by operating mechanism engaging with the movable jaw me alone, such
mechanism, in the present instance shown, consisting of a pivoted lever m³ which is
operated by a cam or eccentric m² on the driving shaft a³ and connected with an
arm or part mo of the gripper jaw me through the medium of a connecting link m".
Said lever m³ is held in operative contact with the cam m by a spring m³.
The gripping device being thus operated, I provide frictional engagement
between the sliding plate m' and its guide-plate, tending to retard the movement of
the plate, so that when pressure is applied to the upper end of the gripper-jaw m³.
in a direction to carry the said upper end of the arm forward, the gripper-jaw will
first be depressed, after which a continued forward pressure upon the end of its
arm will
carry the sliding plate and gripping jaws bodily forward. Likewise when
the pressure is applied to the arm of the movable jaw me to move the same back-
wardly, the jaws will first be opened and the entire gripping device be then moved
bodily backward. Any suitable means may be employed for producing such
frictional engagement between the sliding plate m' and its guide-plate. The means
employed as herein shown, see Figure 27, comprises a flat spring me which bears
at its centre against the plate m³, and two screws or pins m17 which extend loosely
through said plate m² and have screw-threaded engagement with the plate m',.
whereby the spring may be caused to hold the plates m' and m² in contact with the
opposite sides of the plate M¹ with more or less pressure as may be desired.
In applying the jointing-strips upon the corner of boxes of different sizes it is
desirable that the distance to which the strip is fed forward past the cutting or
severing device at each advance movement of the feeding device, should be capable
of variation in order that the length of the strip used upon the box may correspond.
with the depth of the same. In connection with the stationary die or anvil-block,.
which is adjustable to afford a greater or less distance between the end of the same.
and the cutting mechanism as herein before described, I have provided a connecting
mechanism between such movable anvil-block and the feeding device actuating
mechanism, whereby the movement of the block a certain distance will produce a
corresponding change in the throw of the gripping-jaws, whereby the length of the
strip fed at each reciprocation of the feeding jaws will correspond with the length.
of the exposed part of the anvil-block and the joint to be made.
The means as herein illustrated for securing such connection, consists of a lever o
which is pivoted upon the frame at o' with one end connecting with the anvil-block
to be moved thereby, and its opposite end extending in a position to be engaged by
the feed operating lever or part thereof at the limit of its backward throw and
form a stop for the same. By this arrangement of parts, when the anvil-block is.

page_text: moved outwardly, the upper end of the lever o is thrown backward and allows a
correspondingly greater backward throw to the feed operating lever m³ and cou-
sequently a greater movement to the gripping-jaw. When, on the contrary, the
anvil-block is moved inwardly, the upper end of the lever o is thrown forward and
limits the throw of the feed lever m³ accordingly to decrease the distance at which
the stay-strip is fed forward at each action of the feeding device.
"
An adjusting-screw o² is supported by the lever m8 with one end in position to
be engaged by the lever o and forms an adjusting medium between said parts,
whereby the throw of the feeding device may have an adjustment independent of
the automatic adjustment secured by its connection with the anvil-block as
described, in order to be regulated for any desired length of stay-strip regardless
of the depth of the box being operated upon, and also to take up for wear of
the parts.
A further adjustment of the feeding device is secured by locating an adjusting-
screw m¹³ in an arm or extension m¹ of the sliding plate m', at a point to engage the
arm of the movable gripping-jaw mand regulate the vertical or upward movement
of its working face or end to conform to stay-strips of different thickness. By
such adjustment of the movable gripping-jaw it may also be made to bite or engage
the strip sooner or later at the beginning of its forward movement and consequently
regulate the length of strip fed forward, as will be readily understood.
Any suitable means may be employed for guiding the stay-strip from the
scraper L to the gripping-jaws and from the latter to the clamping dies, a simple
and convenient construction for such purpose as herein illustrated, consisting of a
longitudinal guide-bar p which is arranged in line with the centre of the stay-strip,
and with its upper and guiding surface in approximately the same horizontal plane
as the working face of the lower gripping-jaw m³ and in position to engage the
under surface of the stay-strip at a point within the seam or crease thereof. This
guide-strip, which is supported at each end upon the guide-plate M in the position
described, serves to guide the strip and hold the same in proper position with
relation to the gripping jaws, to prevent an undue bending or twisting of the strip
when the same is engaged by and between the said jaws.
The folder J, through which the stay-strip is passed to be folded and take a
V-shape as and for the purpose herein before described, consists of two vertically
arranged plates or jaws j, j, between which the stay-strip is passed to be creased,
which are supported upon a stationary plate j' in a manner to be adjusted in their
relation to each other according to the thickness of the material forming the stay-
strip and also for the purpose of producing a crease of more or less sharpness as
may be required in material of different kinds. Each of said creasing jaws, as
more clearly shown in Figure 11, are carried by plates j2j2, which are arranged to
slide on the plate and are provided with lugs on their under side having
screw-threaded openings therein to receive a threaded stem by means of which
the creasing jaws are adjusted. This said stem is centrally mounted to turn
or rotate in a suitable bearing in a lug on the under side of the supporting
plate, and is formed with a right and left hand screw-thread at opposite sides of
its bearing for engaging with the lugs whereby the creasing jaws may be
moved to and from each other by a single operating stem as described. The latter
is provided with a knob je as a convenient means by which it may be operated.
The plate is provided with an upturned flange at one end thereof having a
guide-opening through which the strip is entered, and with side walls j
arranged at some distance apart at their rear end, so as to gradually bring
together the margins of the strip and guide the same in a folded position between
the creasing jaws jj.
The folder J, see Figure 1, is supported on a vertically adjustable holder or
support whereby it may be adjusted, according to the width of stay-strip being
used, so as to bring the upper edge of the folded stay-strip in line with the top of
the paste-wheel and secure a uniform line of travel for the same. Said holder 13
is supported on a stud j" on the bed-plate H and is adjustable thereon in the present

page_text: instance shown, by means of an elongated opening is located therein and a
'set-screw which engages with said holder and extends through the opening
therein into engagement with the stud 14.
A guide-plate is adjustably supported in a position above the guiding
walls at the rear of the creasing jaws jj, in order to engage the upper edge or
fold of the stay-strip and hold both lower edges against the plate ji to insure the
folding of the strip at its centre as it is passed between the jaws jj. Said guide-
plate is supported in a vertically movable position on a threaded post 10 located
on the plate, and is held in contact with an adjusting-screw to be moved
vertically, either up or down therewith, by means of a spring 12. Such adjustment
of the guide-plate is necessary to move the same for different widths of stay-strip
employed..
The presser-roll K¹ supported above the paste roll K, is carried by an arm
extending from a block or collar k, which latter is supported on a post or standard k
in a manner to rotate and be vertically movable thereon, whereby the roll may be
adjusted to bear with more or less pressure on the pasting roll according to the
thickness of the stay-strip, and also be removable from its position over said pasting
roll to allow for the ready placing of the stay-strip thereon when the latter is first
placed on or through the several parts from the roll, preparatory to using the
machine. The presser-roll is held in yielding contact with the pasting roll to
be self-adjusting to material of different thickness and also to any irregularities of
the same, by means of a spring 2 which is supported on the post with one end
having a bearing against the block k and its opposite end bearing against an
adjusting-screw located on said post, the latter being threaded part way of its
length for the operation of said adjusting-screw. The tension of said spring upon
the block k to cause the presser-roll to bear with more or less pressure upon the
pasting roll, is regulated by the adjusting-screw k³ as will be obvious.
The presser-roll is movably locked from rotary movement in a horizontal plane,
by means of a pink on the post which is adapted to be received in a slot or
opening located in the lower edge of the block or collar k, as more clearly shown
in Figure 13. In order to move the presser-roll from above the paste-roll, the
collar is simply raised from connection with said pin k³ and is then free to be
turned as desired.
S, Figures 1 and 13, is a scraper adapted for removing the superfluous adhesive
material from the paste-wheel before reaching the stay-strip and regulate the
quantity to be placed on the latter.
The scraper L, herein before referred to, is more particularly adapted to spread
the adhesive material uniformly upon the stay-strip after passing over the paste-roll
and also remove the superfluous material therefrom. This device consists of two
plates and which are supported, one above the other, on a post or rod *
projecting from the tank or receptacle 1³, and are formed to present a V-shaped
opening between their adjacent faces to receive the stay-strip which is fed to the
same in such form. One of said plates is adjustable in its relation to the other in
order to vary the space between the same for different thickness of stay-strip, by
nieans of an adjusting-screw ', which, in the present instance shown, is supported
in a vertically stationary position on an arm of the post with its threaded end.
in engagement with an arm or part of the plate l', to move the latter vertically
and adjust the same.
The adjacent. edges of the plates and are constructed to he movable, one past
the other, in a manner as clearly shown in Figure 14, which represents a vertical
section through said plates, whereby they may be regulated to remove more or less
of the adhesive material from the stay-strip without liability of tearing or otherwise
damaging the latter, as might be caused if the strip engaging surfaces were
arranged to move in the same line to or from each other and thereby be liable to
pinch or bite said strip between the same.
The scraper L, as herein shown, is detachably supported
supporting post- being seated within a suitable socket or seat
on the tank 1, its
at one side of said
α

page_text: tank, as it is obvious that when a previously prepared gummed strip is used, such
scraper is not necessary and therefore it is desirable to have the same removable
from the path of said strip.
The machine herein shown is arranged to be operated by power, the same being
provided with a belt-wheel R on the driving shaft, although it is obvious that
the same may be arranged to be actuated by a foot-lever or other convenient
means.
Having thus set forth my invention and illustrated the same in one practical
form, it will be obvious that the machine shown may be more or less modified as to
the various details of construction and arrangement of the parts, and certain
features be entirely omitted, without departing from the spirit of my invention.
