Improvements in Machines for Making and Driving Wire Staples,
Chiefly Designed for use in the Manufacture of Boots and Shoes.
I, PETER AMABLE COUPAL, of 710 East Fifth Street, in the City of Boston,
in the County of Suffolk and State of Massachusetts, United States of America,
Machinist, do hereby declare the nature of my invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention has for its object to provide a machine adapted to make staples
from a continuous wire, and drive the same into a boot or shoe sole for the purpose
of securing said sole to the inner sole and upper, and to automatically vary the
length of the staples so that their length may correspond to the particular portion
of the boot or shoe bottom into which they are driven, so that the staples driven
may be automatically conformed in length to variations in the thickness of the boot
or shoe bottom and to any thickness of bottom that may be employed.
The invention has most particularly for its object to vary the length of the
staples without causing any variation in the length of the legs of each staple, so
that in changing from the production of a shorter to the production of a longer
staple the increase in length will be distributed uniformly, both legs being
correspondingly lengthened. This is a feature of much importance, it having been
found very difficult, if not impossible, heretofore to effect a change in the length of
the staples without making at least one staple with legs of unequal length.
The invention also has for its object to produce staples having pointed legs, the
points of which are substantially in line with one of the longitudinal sides of the
legs, or, in other words, are beveled on one side without cutting out chips or pieces
of the wire in forming said beveled sides.
The invention also has for its object to provide various other improvements
looking to the production of an efficient and simple machine for making and driving
staples into boot and shoe bottoms.
The invention consists-first, in an organized machine in which are combined an
anvil and a reciprocating former which co-operate in bending a length of wire into
a staple, the anvil being arranged to retreat from the staple after the bending
operation, cutters arranged to sever the wire preparatory to the operation of bending
it into a staple, a reciprocating driver arranged to drive each staple into a boot
or shoe bottom presented to the machine, a work supporting horn arranged to
support the boot or shoe bottom for the action of the driver, a wire feeding device
whereby the wire is fed forward for each staple, and connections between the work
supporting horn (which is vertically movable) and the wire severing cutters and
wire feeding devices whereby any change in the vertical position of the horn, such
as would be caused by variations in the thickness of the work interposed between
the horn and the throat of the machine, are caused to effect two results, iz.: to
increase the feed of the wire so that the forward end of the latter will project an
increased distance over the anvil, thus increasing the length of one leg of the staple
next formed; and, secondly, the cutters will be moved away from the anvil a
distance corresponding to the increase in the feed movement of the wire, so that the
other leg of the staple will have a corresponding and equal increase in length. The
invention also consists in the combination with the wire cutters arranged to sever
the wire diagonally and thereby form pointed ends on the main wire and on the
severed length, of means for bending one of the pointed portions so that the point
instead of being left in the plane of one edge of the wire, as it would be without
the bending operation, is left in the plane of the opposite edge of the wire, thus
giving both legs of the staple a tendency to turn in the same direction. The

page_text: auso consists in various other details and combinations of parts relating
to a staple making and driving machine, all of which will now proceed to
describe and claim."

In the drawings,
a represents the supporting standard or pedestal on which is mounted the head
or frame supporting the driving shaft e To said shaft are affixed the cams,
hereinafter described, which give motion to the various parts of the machine.
d represents the throat through which the staples are driven into the work,
and e represents the horn that supports the work under the throat d. represents
the driver which is attached to a vertically movable slide fitted to move in a guide
in the head or frame b, and is reciprocated by means of a cam groove in a disc on
a driving shaft, said groove being shown in dotted lines in Fig. 7, and receiving a
trundle roll on the slide y. The driver is reciprocated vertically by the rotation
of the driving shaft, and when it descends it enters the staple receiving channel in
the throat and drives the staple therefrom, as hereinafter described. represents
the anvil or former over which the wire is bent into a staple. Said anvil is horizon-
tally movable in a guide in the head and is reciprocated by means of a lever k,
pivoted at to the head and having a trundle roll mat its upper end engaged
with the cam groove a in a disc on the driving shaft, and a link o
lower end of said lever with the rear end of the anvil, as shown in Fig. 15.
connecting the
p represents the former which bends the wire into a staple over the anvil. Said
former has a slot which is adapted to receive the auvil when the former is

page_text: depressed, the sides of said slot and the sides of the anvil co-operating in bending
the wire into a staple. In Fig. 14 the wire q is shown extending across the anvil
and under the former, the former being raised preparatory to its descent to bend the
wire into a staple. The shank p' of the former extends upwardly and is provided
at or near its upper end with a trundle roll p² which enters a cam groove p³ in a disc
on the driving shaft, whereby the former is vertically reciprocated by the rotation
of said shaft. represents a lever which is mounted to oscillate upon a stud s
affixed to the head, said lever having its outer end formed as a segmental slide or
head, which is supported and adapted to move upon a segmental guide formed
on the head. The lever is provided with a bearing for a feed roll shaft u, which
is journaled to rotate freely in said bearing and is provided at one end with a feed
roll, the periphery of which has a groove formed to receive the wire q. w repre-
sents an idle roll which is pressed by a spring against the roll and into the
groove thereof, said idle roll keeping the wire in operative engagement with the
roll. The roll is rotated to feed the wire by the following means, wiz.: a ratchet
wheely affixed to the shaft w, a dog or pawl pivoted to an arm a', which is
mounted to oscillate loosely upon the shaft and has a pinion 6' formed upon it,
and a rack meshing with said pinion, said rack being pivoted at its upper end to
a lever which is pivotally connected at e' to the head or frame and carries a
trundle roll, Fig. 9, which enters a cam groove in a disc upon the driving
shaft. The rotation of the driving shaft causes the lever to oscillate vertically.
and reciprocate the rack e', the latter, by its engagement with the pinion, causing
the arm a to oscillate and thereby carry the pawl back and forth over the ratchet y,
the movement of the pawl in one direction causing it to rotate the shaft u and feed
roll e, as will be readily seen.
1:
The work supporting horn e is vertically movable as already stated, so that its
upper end or anvil which supports the under surface of the boot or shoe bottom is
separated from the throat d by a space equal to the thickness of said bottom, said
space being variable according to the thickness of the bottom. I have provided
means whereby the vertical position of the horn, or, in other words, the extent of
its separation from the throat d, will determine the extent of the feed movement
given to the feed roll by the pawl and its operating mechanism above described.
To this end connect one arm of the lever with a lever 1, Fig. 4, which is
pivoted at to the head or frame, and is connected at its opposite end with a
vertical rod which extends downwardly and is connected at its lower end with a
lever, which is pivoted at to the standard a and is connected at one end
with a collar m' on the standard o' that supports the horn e. When the horn is
depressed it communicates, to the lever through the described intermediate
devices, a motion in the direction indicated by the arrows in Figures 12 and 18.
represents a sleeve or collar mounted to rotate loosely upon the feed roll shaft u
and provided with a flange s', to which is affixed a gear wheel t' which meshes with
a rack segment attached to the frame or head. To the flange
is attached a segmental shield e¹ which partially covers the ratchet wheel
and is adapted to throw the pawl = out of engagement with the teeth of
said ratchet during a greater or less part of the movement of the said pawl when
the latter is moving forward to rotate the ratchet. The described movement of the
lever in the direction indicated in Figures 12 and 18, by the depression of the
horn, causes the fixed gear segment u 10 rotate the gear and the flanged sleeve
thereto affixed, in such direction as to draw the shield backwardly so that it will
permit the pawl to remain in engagement with the ratchet during a greater
portion of its forward movement than before, so that the extent of the feed move-
ment imparted to the feed roll is increased by the depression of the horn, the
extent of the increase depending upon the extent of the said depression. This
increase in the extent of the feed movement causes the feed roll to feed the wire
farther across the anvil, so that the leg of the staple formed on the right hand
side of the anvil, as viewed in Fig. 14, will be increased.
י

page_text: on
The same movement of the lever is caused to correspondingly increase the other
leg of the staple by the following means: Attached to the segmental head
the lever is a cutter of hardened steel. represents a corresponding cutter on
a lever which is pivoted at to an ear on the segmental head. Said
lever has a lug or car y which projects upwardly and is provided with a trundle
roll, which engages a groove in a segmental head a² formed on a vertical slide 12
which is fitted to move in a guide in the head or frame , said slide having at its
upper end a trundle roll e² which enters a cam groove in a dise on the driving
shaft.
The rotation of the driving shaft reciprocates the slide 2 vertically and causes
the lower edge of its segmental head to press downwardly upon the lever .c²,
thereby depressing the cutter al on said lever and causing said cutter to co-operate
with the cutter in severing the wire said cutters being arranged to extend
diagonally across the path of the wire, so that in severing it they give each end
formed by the severing operation a diagonal form, whereby both ends are
pointed.
"
It will be seen that the cutters and are both carried by the lever and its
head, so that the described movement of the lever caused by a depression of
the horn will move the cutters and away from the anvil to an extent equal to
the increase above described in the feed movement of the wire by the feed roll.
The other leg of the staple, ri:.: that which is formed by bending down the end of
the wire between the anvil and the cutters, is thus made of the same length as the
opposite leg, the increase in the length of the staple being therefore equally dis-
tributed.
e² represents a wire guide attached to a dovetail slide which is fitted in a dove-
tail guide in the head, the wire passing through a channel e³ in said guide
is
between the feed roll and the cutters w' and ..
On the upper surface of the cutter is formed a shoulder 2 which is oblique to
the cutting edge of said cutter, and is arranged so that when the wire guide
moved from the position shown in Figures 21, 26 and 28 to that shown in
Figures 22, 27 and 29, the pointed end of the wire in said guide will be pressed by
said movement against the shoulder and will be bent by contact with the latter,
the point of the wire being thereby bent outwardly, as shown in Figures 22, 23,
27 and 29. The adjacent point q³ on the rear end of the blank, or the portion of
wire that has been cut off, is not bent by this operation but remains in line with the
outer edge of the wire, because the wire is severed by the cutters before the bending
operation, so that the blank is detached from the portion of the wire that is engaged
by the wire guide e, hence when said wire guide is moved, as described, to bend
the point against the shoulder w², the blank remains in the position in which
it was when severed from the wire, as shown in Fig. 29, and is not moved laterally.
Figures 28 and 29 show the parts in the same positions as in Figures 21 and 22,
and also show the blank in the position it occupies during the operation of bending
the point . The bending of the point by the above described operation is suffi-
cient to carry said point across the longitudinal centre of the wire and bring it in
line, or nearly so, with the point 3, so that when the staple formed from the blank
is driven both its legs will be clinched in the same direction, as shown in Fig. 25.
It will be seen, therefore, that the staples may be driven into the sole of a boot or
shoe in such position that the legs of the staple will be turned or clinched inwardly
toward the centre of the sole, so that there will be no liability of the staples being
turned outwardly and passing through the edge of the sole.

The slide is moved to cause the wire guide e² to bend the wire as described, by
means of a screw or stud 2 in a post on the anvil (see Figures 19 and 20) and
an arm attached to the slide and arranged to be moved by contact with the
stud when the anvil is moved backwardly to clear it from the staple, said move-
ment of the anvil carrying the wire guide to its bending position shown in Fig. 22.
When the anvil is moved forward a spring ³, interposed between the rear end of

page_text: the slide and a part of the lever r. presses the slide and wire guide outwardly,
the outward movement being limited by a stop screw attached to the lever
head r.
A represents a feed dog which is pivoted at B to an ear on a slide C which is
fitted in a dovetail groove in the head, said dog being located just behind the
throat d (see Figures 10 and 11). The slide C is reciprocated horizontally to give
the feed dog its forward or work feeding, and backward or retracting movements,
by means of a lever D which is pivoted at E (Fig. 7) to an ear on the head, and
is arranged to bear at its upper end against a cam G on the driving shaft, the lower
end of said lever being pivoted to the slide C. The cam G is formed to oscillate
the lever D by the aid of a spring H (Fig. 4) which holds the upper end of the
lever against the cam G. The feed dog is oscillated on its pivot B so that it is
depressed during its horizontal movement one way, and raised during its horizontal
movement the other way. Said oscillating movements of the cam are effected by
means of a bell crank lever 1 1¹ mounted on a stud which is journaled in ears K K
on the head, and a link L connecting the arm 1 of the bell crank lever with the
oscillating lever which imparts motion to the anvil j. The arm I of the bell
crank lever is adapted to oscillate to a certain extent independently of the arms
and is connected thereto by a spiral spring 0 (Figures 10 and 11). One end of
said spring is connected with the arm and the other end with one of the arms P,
said arms being connected by a pin M which passes through a slot N in the rear
end of the dog A.
The spring O gives the feed dog a yielding pressure on the work, as will be
readily seen.
The machine is provided, as usual in nailing machines in which the
work is supported by a horn, with suitable means whereby the horn is positively
depressed after the driving of each staple to permit the feeding of the work, said
means being a lever S (Fig. 3) pivoted at S¹ to the standard a and engaged at one
end with a collar T on the horn standard o¹, a rod V connected with the other end
of said lever and a stud W (Figures 4, 5 and 19) at the upper end of said rod,
entering a cam groove Y (Fig. 9) in the rear side of the disc X on the driving
shaft. The collar T rests loosely on a collar U which is attached to the standard o'
and when the rod V is raised by the action of the cam groove Y the lever S is
turned so as to depress the collar T and the horn standard and horn. A spring Z
raises the horn as far as the collar T will permit.
The driving shaft is provided with a driving pulley A having a hub B', said
pulley is normally loose on the shaft and is provided with a suitable clutch whereby
it is connected with the driving shaft by a depression of a treadle C, Fig. 1, said
treadle being connected by a rod D' with the automatic clutch. Any suitable
clutch mechanism may be employed.
The operation of the machine is as follows:
The anvil being in its forward position under the former and the former being
raised above the anvil, the wire is fed forward by the feeding devices across the
anvil, the length of wire fed across the anvil and the distance of the wire cutters
from the anvil being determined by the thickness of the stock between the throat d
and horne, the wire being fed farther across the anvil and cut off farther from the
anvil when a sole of maximum thickness is interposed between the throat and horn
than when a thinner sole is so interposed.
The cutters sever the wire immediately after the feeding thereof, and the former
thereupon descends and bends the severed length of wire into a staple. The anvil
is then moved backwardly leaving the staple, which is immediately thereafter driven
by the descent of the driver, the wire guide e being moved with the anvil to bend
the point as above described.
The feed dog is depressed and engages the bottom of the sole while the driver
is descending, and is moved to feed the sole forward to position to receive another
staple while the driver is ascending.
As already indicated, a very important feature of my invention is the provision
of means for the automatic adjustment of the cutters relatively to the anvil, and the

page_text: automatic adjustment of the length of the feed movement given to the wire, both
of said adjustments being determined simultaneously by the position of the horn.
It is not new to adjust the length of the feed movement of a continuous wire by
the position of the horn in a machine which makes single mails, said adjustment
being effected by means of a shield which is connected by intermediate mechanism
with the horn and determines the extent of rotation imparted to a feed roll by an
oscillating pawl; but I am the first, so far as I am aware, to combine automatic
means for the adjustment of the length of the wire feed with automatic means for
the adjustment of the wire severing cutters, and staple forming devices so arranged
relatively to the wire and cutters that the automatic adjustment of the feed
determines the length of one leg of the staple and the automatic adjustment of the
cutters determines the length of the other leg, hence I do not limit myself to the
particular details of mechanism herein described, whereby said adjustments are
simultaneously effected.
The provision of means for bending one of the points formed on the wire, so that
both points will be at one and the same side of the longitudinal centre of the wire
that forms the staple, is also an important feature and is new with me, hence the
means for effecting said bending may be variously modified without departing from
the spirit of my invention,
