Improvements in Machines for Feeding, Damping, and Attaching
Stay Pieces to the Corners of Paste-board and like Boxes.
I, HORACE INMAN of Amsterdam, Montgomery County, State of New York,
United States of America, Manufacturer, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to improvements in machines for attaching stays to the
corners of boxes, and it consists in the general construction, arrangement and
combination of parts of the machine as herein described and shown in the drawings
hereof.
My improved machine is of the class now well known for applying to the
corners of boxes made of paste-board, straw-board, veneer and other like materials,
staying pieces or strips composed ordinarily of paper, linen or other textile fabric,
whereby the corners are supported and made strong.

A, is the standard of the machine. It is preferably made of cast iron as usual
in such cases.
B is the upper part of the frame and is also preferably a casting.
It is bolted, as at C. C, to the top of the standard A. D is the driving wheel
which is mounted upon a shaft E which turns in bearing F, F, in the casting B, B.
G, G, are oil cups for lubricating the journals working in the bearings F, F. H, is
a cam keyed to the shaft E. At its forward (see more particularly Figs. 3, 8 and 9)
the shaft E is provided with a crank I. J is a sleeve which is slipped on the
crank I, and this sleeve has at one side a thickened portion K, which is eccentric
to the axis of the sleeve. L, is a lever adapted to be slipped on the forward end
of the sleeve and is provided with a number of pins N (see Fig. 9) which enter
holes M (see Fig. 8) in the thick part of the eccentric of the sleeve J. This
lever L (see Figs. 2 and 8) is provided with a slot O, through which pass
screws P, P, which engage with a bearing block Q, which slides through a
slideway R, made in the head of the plunger S. The plunger S, moves through
a slideway T, on the front of the machine and at its lower end the upper die and
its co-acting parts are arranged as will be hereinafter explained. The front of
the slideway T, may be removed by unscrewing and taking off the front plate, as
shown at T. U, is a cap (see Figs. 2, 3 and 9) which is screwed to the end of
the sleeve J, and confines the lever L, in place. This cap is removed in Fig. 8.
V (see Fig. 1) is a treadle which is pivoted to a vertical rod W (see Figs. 1 and 3)
which extends upwardly through the centre of the standard and through an
opening A', in the casting B, and at its upper end it is pivoted to a bell-crank B',
which is pivoted at C', to the frame B. The upper end of this lever engages
with the horizontally sliding pin D' (see Fig. 1) which is normally pressed to the
left by a spring E; the driving wheel or pulley D (see Fig. 12) is loose on the
shaft E, and that shaft is provided with a spring pawl F, which engages during
the revolution of the shaft E, with the end of the pin D', which projects so as to
engage with it. G', is an annular rack on the hub H', of the driving pulley D,
with which the pawl F¹ promptly engages the instant the pin D¹ is withdrawn by
the application of pressure to the treadle V. and when that pressure is removed, the
spring E again projects the pin which immediately thereafter engages with
the pawl F and lifts it out from the rack G', and the motion of the machine
ceases; the construction and arrangement of the parts being such that the plunger
is always elevated and the dies separated when the machine stops.
The arrangement of the dies and of the devices which press upon and hold the
corner staying material, and bend it downwardly and inwardly so as to apply it to
the inside of the corners of the boxes are as follows, special reference being had to
Figs. 3, 5, 6, 10, 11, 19, 21 and 22. On the lower end of the plunger S, there is
formed a horizontal plate H', which has a vertical flange II, and through the flange
screws J¹ pass which fasten a block K' to the flange I and to this block, the parts
composing the upper die are attached, so that by simply unscrewing the screws or
bolts
all of these parts may be taken away from the machine for repair. To

page_text: the front of the block K' is screwed a plate L', in which is a slot Q1 (see Figs. 2
and 5). The upper die M' is provided with two upwardly extending studs or
fingers N¹, N', having cushions O, O', above them, which are housed in recesses or
cavities in the block K'. The die M' has a lip P', which moves in the slot Q¹,
made in the plate L'. On the other or rear side of the die M', there is a vertically
moving plate R¹ (see Figs. 10 and 11) having two upwardly extending parts S¹
which straddle a screw or bolt T', and a spring U which encircles a spindle V¹
which is fastened to the plate R', and abuts at its upper end against a stud W¹ on
the flange or on the block K as the case may be, which normally depresses the
sliding plate R¹. A2 is a stud fastened to the face of the sliding plate R¹, which
engages with the lower end of a swinging and vertically movable part B2, which I
will call the tucking finger. It is pivoted by pivot C2 to a rocking lever D2, which
is pivoted at E2, to the flange I. At its rear end this lever D2 is provided with a
set screw F2, which engages with a stop G2, on the frame of the machine and on
the under side of the stop G2 and attached to the lever D2 by bolt H2. are
springs I, so that as the plunger rises and falls, the lever D², will he rocked upon
its pivot E, by the impingement of the set screw F2 in one direction and the
springs 12, in the other against the stop G2, and it will be noticed that the set
screw F, is adjustable by means of the set nut J2, so that I can adjust exactly the
downward movement of the forward end of the tilting lever D². It will also be
noticed that the tucking finger B2 is slotted where the pivot C2 passes through it
(see Fig. 21) and that within the slot is a spring K2, which normally depresses the
tucking finger B². This is provided so that the tucking finger may move under
the corner of the box, loose, so to speak, prior to the squeeze of the upper die and
also so that the upper die may continue its downward movement and not affect the
position of the tucking finger; if the construction of the parts and their adjustinents
be suitable, this spring will not be necessary, because the spring of the parts, plus
inevitable lost motion will permit the stated operation of the parts even if the
spring be omitted. I employ an automatic oiler (not shown) in connection with
the tucking finger, so that it is lubricated at its lower end where it comes in contact
with the plate a, at each operation of the machine.
Referring to Fig. 19, the lower end of the tucking finger is cut out on its forward
end, so as to produce three thin edges or plates, two lateral ones a³, a³, which are at
right angles to each other, meeting on a right angle at the top, and a central one 6³,
midway between them. The central one ³, first comes in contact with the
upwardly presented angle of the projecting staying strip, and breaks it down before
the side plates a³, a³, act upon it; thus the strip is folded upon the inside of the box
corner smoothly and without wrinkles or breaks. The outer surfaces of the side
plates a³, a³, being at right angles to each other, properly fit the corner of the box
on its inside and press the folded in part of the staying strip thereon.
Referring now to the lower die and its co-acting parts; L2 is a heavy bar of any
preferred cross section (shown cylindrical in the present instance) which slides
horizontally through an opening in the main casing. It is recessed at its rear end
as at M2, which recess is interiorly threaded (see Fig. 5). The threads engage
with like threads on the part N2 of the spindle O2, which is collared as at P², against
a block or stop Q2, which is threaded into the casting B, and is provided on its
outer rear end with a hand-wheel Q³, so that by turning the hand-wheel the bar L²
is moved forwardly or rearwardly through the machine. R2 is a spindle which
slides longitudinally through a hole S2 made in the forward end of the bar L2 and
on the forward end of the spindle R2, is a plate T2, the upper end whereof is made
rectangular so as to fit the corner of the box, and U2 is a set screw whereby the
spindle R2 may be held in any desired projected position. There may be a groove
along the under side of the spindle R2 if desired, in which the end of the set screw U²
may engage to prevent rotation of the spindie. V is a circular piece of metal cut
out at its upper surface as at W2 (see Figs. 2, 13 and 20) and against this circular
plate the most forward edges of the boxes or covers as the case may be, abut. To
the upper surface of the bar L' is screwed a plate a (see particularly Figs. 5 and 14)-

page_text: which
This plate has two holes through it b, b. c is the lower die. It is supported upon
the plate a by a downwardly extending piece of metal d which passes through one
of the openings b in the plate a and catches under that plate by entering a longi-
tudinal passage or groove eo made in the upper surface of the bar L2 (see Fig. 15).
The other end of the die c is held in place by a piece of metal f which is fastened
at its upper end to the die c and at its lower end to the bar L² by a screw
passes through it and enters the bar. The connections between these parts are not
rigid. On the contrary they allow considerable lateral movement of the lower die
for reasons hereinafter explained. The under side of the die c is made convex or
rounding (see particularly Figs. 2 and 20) and it will be observed that since the
means for holding the die upon the plate a are not rigid they allow a rocking
motion of the die c. This has a co-acting effect in conjunction with the upwardly
yielding upper die M' during the first portion of their squeezing action upon the
staying material, because owing to there being nothing rigid or absolutely fixed in
the position or exact angles of these dies relative to each other, they will readily
vield to accomodate themselves to differences in thickness of the material between
them. This is a valuable feature of my machine, for I ordinarily apply great
pressure through my dies, much more than is usually employed in such machines,
and strawboard which is the material from which the boxes are most generally
made is very apt to be irregular in thickness, also in density, and is also apt to have
foreign matter in its body, and if the dies were not adapted to accommodate
themselves to these irregularities or differences, fracture of the machine might
result, and in any event the pressure upon the two sides of a box corner would
frequently not be even, and since I prefer to use but little adhesive material and
heavy pressure it is important to have the pressure equal on both sides. I find
that but little adhesive material and considerable pressure gives much more
satisfactory results than the old methods, because the corners of the box are
smoother and more firm and the staying strip is partly embedded therein, so that
the thickness is reduced. The two slots or holes b are made in the plate a, so that
when the lower die is a short one the finger d may be placed in the left hand
opening or slot b, and it will catch under the rib which runs across between these
openings and hold the die in place. Where the die is very short I arrange the
parts as shown in Fig. 16, that is to say, I attach to the underside of the short die
a long finger or wire e which is substantially the same shape as the finger d of the
other die, except that the horizontal part is much longer and this long finger enters
a notch a (see Fig. 14) and extends through an elongated channel or hole a* cut
or made in the bar L².
To consider now more specifically the devices which press upon, hold and turn
the portion of the staying strip which projects beyond the edges of the boxes
inwardly over those edges and adjusts the same to the inside of the boxes, special
attention is called to Figs. 5, 6, 10, 11, 19, 21 and 22. The parts when at rest
before descent are in the position shown in Fig. 5. As the plunger descends it
carries down with it the pressure plate R¹, which being depressed by the spring U1
is about even with the lower edge of the die M', which it will be noticed is depressed
by the springs O', and the stud A2 upon the pressure plate R' engaging with the
lower end of the tucking finger B2 carries that down with it, tipping the lever D²
in so doing; thus soon bringing the set screw F2 down upon the stop G2. After
the plunger carrying the parts above stated has descended a certain distance
(see for illustration Fig. 21) the two dies come together, clamping the box
corner and the staying material between them with however a yielding pressure
because of the springs O which permit the plunger still further to descend
without however depressing the upper die M' and about this time the pressure
plate R has also reached the staying strip and presses upon it, the adjustment
of the parts being such that the corner of the box is so located by the guide
plate V2 that the pressure plate is just covered by the protecting edge of the
box, in other words the box projects inwardly beyond the inner end of the die M',
a distance about equal to the thickness of the pressure plate, and the parts being

page_text: in the position above set forth the lower forward point of the tucking finger B2
sliding downwardly in contact with the surface of the plate a engages with the
projecting end of the staying strip, bending it downwardly, and the plunger further
descending causes the tucking finger to descend still further and make contact with
the upper side of the plate a, and owing to the fact that the point of first contact is
forward of the point of support, i.e., the pivot C2, the tucking finger is swung
inwardly under the plate R', and also under the inner end of the die M' carrying
the end of the staying strip with it. The parts then assume the position shown
in Figs. 6 and 22. The plunger S continues to descend, still further compressing
the springs and closing the opening between the lower side of the block K' and
the die M. Thus it will be observed that the pressure plate R' which maintains
its pressure upon the staying at the edge of the corner during the above stated
operations holds it against displacement and prevents it from buckling or
"humping" up as it is called, while the tucking finger is bending it downwardly
and carrying it to the inside of the corner of the box.
And it will also be observed that the front end of the tucking finger, being
formed with the three edges or plates a³ and b³, that the portion of the carrying
strip that is carried within the corner is folded and bent in such manner as to be
free from wrinkles and that the total result is a smooth handsomely finished and
securely stayed corner. As before stated, by the time the tucking finger has
reached its ultimate position under the upper die then the plunger proper or rather
he block K attached to it makes contact with the upper side of the upper die and
the final squeeze is exerted upon the box corner and upon the staying strip,
whereby the latter is firmly pressed upon and in fact in most instances partially
embedded in the material forming the box both on the cutside and inside of the
corner, thus making the box smoother and more marketable.
When relatively deep boxes or covers are being made the rod R2 will be projected
as far as necessary so that the plate T2 on its outer end will serve as a support for
the outer or bottom part of the box. It is made adjustable so as to accommodate
boxes or covers having different depths. The plate T2 is rectangular or of such
other shape as to fit into the corner upon which the stay is to be applied, and in
order to properly support or guide the box or cover as a whole I provide what
I term horns k, k, (see Figs. 1 and 2) which if desired may be adjusted toward and
from the machine by screwing them on and off from a stem / (see Fig. 1) and
holding them in any desired position by a set nut m. It will be observed that it is
necessary to adjust the lower die in its forward or rearward position, because the
tucking finger B2 has always a fixed position when in position to receive the final
squeeze, consequently I provide to and fro adjustments for the bar L2 and also the
openings in the plate a whereby I can use lower dies of greater or less length and
when necessary to use very short lower dies, as for instance when making very
shallow covers I provide special means for holding them upon the plate a as before
stated.
Referring now to the devices which automatically dampen and apply the
adhesive material to the strip of staying material, and which cut it off in pieces
for application to the corners of the boxes, special reference being had to
Figs. 2, 4 and 7, n is an arm projecting from the side of the machine, upon which
is fastened a spindle o over which a rotary reel slips and on which it rotates.
This reel comprises or may comprise a metallic disc p and a series of fingers g
which are attached to a hub r. s is a coil of the staying material in the form
of a long strip or tape which is preferably, although not necessarily square in
shape, and provided with a card-board or wooden centre piece which has a hole in
the centre adapted to fit over the spindle o. u (see Fig. 7) is a tray or box
adapted to contain water which dampeus the staying strip, it preferably having
already been treated with adhesive material and only requiring to be dampened to
make it adhere. This box may be of any suitable construction and supported in
any suitable way, but is shown as supported upon a bracket 10 (see Fig. 20),

page_text: projecting from the plate u and held by a thumb-screw u². v, w, are two rollers
suitably journaled on the sides of the box u; the upper one has thumb-
screws y, y, whereby its journals may be elevated or depressed as desired, and on
the shaft of the upper roller there is a ratchet a¹ with which operates a pawl b
normally held up against the ratchet by a spring c. d and e¹ are two levers
which are pivoted together, and 7' is a lever which runs upwardly and is pivoted
at g (see Fig. 3) to the frame of the machine, and it has a short arm h' upon
which is a roller which engages with the cam H on the main driving shaft of the
machine. 2 (see Fig. 4) is a spring which always pulls the lower end of the
lever backwardly so as to maintain the roller on the short arm ¹ in contact
with the cam H.
,, (see Figures 4 and 7) are two rods which project from a permanent block
fastened to one side of the box u, by a set screw or bolt kl and upon these rods j'
slide guides m', n' which are clamped together and held in the desired position
upon the rods by the set screw o¹. The surfaces of the two rollers and ware
grooved as shown in Figs. 4 and 18, the upper roller w being broken away in the
first figure, and these grooves preferably run from right to left, in one of the
rollers, and from left to right in the other, so that they intersect or cross each
other, and in the lower roller which revolves in the water or adhesive material as
the case may be, in the box u, these grooves are filled with thread or cord r which,
becoming soaked with the water conveys it more plentifully and more evenly to
the under side of the staying strip. The grooves intersected or crossed as
described serve to better distribute the water or adhesive material and apply it
to the surface of the strip more evenly. p is a projecting pivoted part of the box
and g' is a comb-like device which is fastened rigidly to the part p', being provided
with lips or lateral connecting plates, there being, however, a space between them
as shown, which is wider at the rear than at the front, where it simply a slit
through which the staying material may pass. is a piece of metal soldered to
the upper side of the comb against which a finger t' (see Figs. 2 and 13) strikes
when the plunger is depressed. The upper side of the part p₁is corrugated or
made in the form of ribs u¹ (see Fig. 7). These corrugations on the upper side of
the part and also the teeth s' of the comb run in the direction of the movement
of the staying material and are provided so that there may be as little surface as
possible against which the staying material v² (see Fig. 7) shall rest during its
passage through the device. These parts p' and q taken as a whole are pivoted at
their rear ends to the sides of the box u by pivots p² projecting from the rear
enlarged part of the part p¹ (see Fig. 17). These pivots p² enter holes in the sides
of the box u and act as axes for the conjoined parts p¹ and g¹; and a spring w
(see Figs. 7 and 13) rests under the edge of the part pl and normally throws it
upwardly thus pulling the staying strip away from the lower cutting die against
which it has been pressed by the upper cutting die at each operation of the
machine, thus preventing any sticking of the strip to the lower cutter, which would
interfere with the proper feeding of it.
Referring to Fig. 3: a² is the upper cutting die which may form part of the
block K¹, or for convenience of sharpening, it may be separate and screwed to one
side of the block. It is moved vertically at each up and down movement of the
plunger S. The counterpart or lower cutting die is seen at Fig. 13 at 62, it being
secured to a portion of the frame by screws. The staying strip or tape is fed by a
pawl and ratchet movement which operates the feeding rollers and w already
explained, between the part p', and the comb q and just the right amount of
tape is caused to project beyond the cutting dies, and as the plunger comes
down, they sever the small piece of the strip necessary for staying each corner,
from the main strip; this takes place immediately after the initial yielding
pressure of the dies has been applied to the staying piece so that no displacement
of it is possible and the spindle t¹, at this time presses the parts p' and comb q
down upon the lower cutting die, so as to lay the staying strip squarely and

page_text: smoothly upon it, that the cutting may be evenly and easily effected, and after
each cut, the spring w³ again lifts the strip free from contact with the lower
cutter, as before stated.
The operation of the machine is as follows: reference being had for the details
of operation of particular parts to the specific description already given. Normally
the driving wheel D turns loose on the main driving shaft. The operator having
adjusted all parts to adapt them to stay the particular boxes or covers desired,
picks up a box and places it over the lower die, and against the supporting
horns k, k, and upon the plate T2 if it be used, and up against the guide plate or
stop V2. He then applies his foot to the treadle, whereupon the pin D₁ is with-
drawn from contact with the spring pawl F1 and immediately that pawl engages
with a tooth in the rack G' opposite to it, whereupon the machine is thrown into
gear and commences to operate. Its first operation is to actuate the feed devices
for the staying strip. Immediately thereafter the plunger commences to descen:1
and the dies primarily and with yielding pressure engage with the staying strip as
stated and hold it; the cutting dies, meantime, cut off the necessary length to stay
one corner, and the pressure plate engages the cut off piece near the edge of the
corner of the box, the tucking finger then folds and bends it downwardly and
carries it within the box corner; during all this time, the plunger has been
descending and finally, when the tucking finger has swung on a curve fully in plac
beneath the corner, the final bard squeeze takes place, and the corner is completed.
The parts then all return to their primary position, the box or cover is moved to
present another corner and the operation is repeated, until all the corners are
stayed.
It will be noticed that in my machine the parts are so constructed and combined
that when properly adjusted and "timed all of the above recited steps or
operations, with the exception of feeding the strip, take place during the descent
of the plunger and in fact are effected by that descent, so that they take place in
succession and with the least possible power and in the shortest possible time.
This latter feature is of great importance and value in this line of manufacture.
This result is obtained because in my machine, there is no backward or reciprocating
movement, and no dwells until the act of staying the corner is completed, and then
all parts return to primary position while the operator is shifting the box from
corner to corner; thus there is no lost time or power. Also in my machine, lower
dies of any length may be placed in position in a moment's time, and without
altering the position and arrangement of any part of the machine, except to adjust
the bar L2; and the lower dies are simply blocks or pieces of metal, all in one
piece and adapted to rock as a whole on their supporting plate, and they being as
a whole, free from longitudinal movement, support the corner of the box during
the entire squeezing operation. Also my tucking finger, because of its movements
first vertically downward then swinging inwardly on a curve under the corner of
the box, performs the dual functions of a bender for the staying strip and as a
tucker to fold it over the edge of the box and tuck it snugly in the inside thereof
during which operations, the pressure plate prevents displacement or puckering on
the outside, and it will be noted that the movements and action of the tucking
finger are almost identical with those of the finger of an operative when this work
is done by hand, that is to say, there is first a bending movement, at say, right
angles to the corner of the box, whereby the staying strip is pushed over, and
then a curved and tucking movement, practically identical with that of the finger
of an operator, which "wipes" as it is called, the end of the strip on to the inside
of the corner and presses it thereon.
I do not limit myself to the details of construction shown and described, because
they may be considerably varied without departing materially from the essentials
of my invention. In particular it is not always necessary to employ the pressure
plate R', the upper die M' may be extended the width of the pressure plate and
the tucking finger will then co-act with it, the same as with the pressure plate.
