Improvements in Machines for Securing Lacing-studs or Staples
to Boots or Shoes.
We, GUSTAVUS TROXLER, Jr., of Newark, residing at 293 Waverly Avenue,
in the County of Essex and State of New Jersey, United States of America, Shoe-
maker, and ISAAC LEVIT SILVERBERG, of 184 South 6th Street, Newark County
of Essex, and State of New Jersey, United States of America, Shoe Manu-
facturer, do hereby declare the nature of our invention and in what manner the
same is to be performed, and to be particularly described and ascertained in and by
the following statement :-
In British Patent Number 20502, dated December 16, 1890, which is for an
improved lacing stud for shoes, is illustrated a form of lacing stud, made from wire,
bent to form a staple provided with pointed ends, adapted to be passed through a
perforated bearing plate and secured to the shoe upper, and a tubular eye or pulley
being arranged on one of the arms comprising the staple.
The purpose of the present invention is to provide a machine for automatically
inserting the prongs of these lacing studs through the shoe upper, bending them
over upon the opposite side of the upper and thereby securely fastening the com-
plete lacing stud to the upper, the machine being of a simple construction.
This invention is further designed to automatically feed a second stud in position
under the punch, as soon as the former stud has been secured in position on the
shoe upper, such second stud being held in a recess in said punch, until it is attached
to the upper by the operation of the machine, when another stud moves down to be
secured in its position in the end of the punch.
In addition to this principle object, the invention is further designed to provide
an operative mechanism for regularly feeding the staples beneath the punch, and
also a simple and effective contrivance whereby the prongs of the staples are pressed
down close to the inner surface of the shoe upper.
The form of construction employed to embody the invention in an operative
machine is illustrated in the accompanying drawings, which show the novel features
of my invention.
In said drawings, Figure 1 is a side elevation of a machine in which is shown
the mechanism selected to illustrate the invention.
Figure 2 is a vertical section taken on line a in said Figure 1, and
Figure 3 is a plan of the machine.
Figure 4 is a side view of the mechanism embodying the present invention, in
a position which immediately precedes that shown in Figure 1, in which position
one of the lacing studs is clearly shown in position in the lower end of the punch,
the stud or staple-holding and feeding galley being in the operation of moving out
of the way of the downward movement of the staple holding punch.
Figure 5 is a similar view, in which position, however, the stud or staple has
been inserted through the shoe upper and the prongs of the stud or staple have
been brought in contact with the upsetting die, whereby the stud is firmly secured
to the shoe upper.

from when the prongs have been turned over upon the shoe upper.
Figure 11 is a plan of the upsetting die, and
Figure 12 is a vertical section of the same taken on line y in said figure.
Figure 13 is a side view and
Figure 14 a top view of the lacing stud or staple chute for feeding the same
beneath the punch;
Z
Figure 15 is a vertical section of the chute taken on line in Figure 13.
Figures 16 and 17 are detail views of an arm to which said chute can be attached
for operating the latter.
Figures 18 and 19 are a top and side view respectively of a lacing stud or staple
carrying galley provided with means for attaching and connecting the same to the
end of the chute illustrated in Figures 13, 14, and 15; and
Figure 20 is a vertical section of the galley taken on line y' in Figure 18.
Similar letters of reference are employed to indicate corresponding parts in each
of the several views.
The machine shown in full in Figure 1 is constructed and arranged to place the
improved lacing stud or staple in a recess or cavity in the lower end of a down-
wardly and upwardly moving punching rod, with the prongs projecting down from
said rod, which, during the downward movement of said rod are forced through the
shoe-upper placed upon a die which causes said prongs to be turned outwardly and
upwardly into the material of the shoe upper, whereby the lacing stud or staple is
firmly secured in position.
To accomplish this, the mechanism consists of a suitable upright A extending up
from a base A', which is bolted or otherwise secured to any suitable stand or
table B.
The upright A is provided with two outwardly extending arms a and a¹ having
suitable openings a² and ³ therein, in which is arranged the upwardly and down-
wardly moving staple holding and punching rod c. Said rod is provided on its
upper end with a slot c' formed by the two upwardly projecting portions c².
Between the arms a and a¹ encircling said rod c is a coiled spring, the lower end
of which is in contact with the upper surface of the arm a', while its upper end is
in contact with the lower side of a washer et, which in turn engages with a
shoulder near the upper portion of said rod c as will be clearly seen from
Figures 2 and 5.
C
Upon the base A' and in line with the central vertical axis of said rod c, is
arranged a die plate d. Said plate d can be suitably secured to the base plate A',
but it is preferably provided with a lug d' on its under side adapted to be inserted
into a perforation formed in a boss a ou said base plate A.'.
e,
The mechanism for producing the downward movement of said rod c consists of a
lever which is fulcrumed between upwardly projecting arms or ears A² on the
upright A, and the forwardly projecting portion el of said levere is provided with
a nosce which extends down into the slot c¹ formed by the arms on the rod c,
while the oppositely projecting portion of the lever e has pivoted thereto a
connecting rode which projects down beneath the table portion of the stand B
where it is pivotally secured to the end of a suitable foot-lever b, by means of which
said connecting rod and the arm can be forced upwardly, causing the nose-
portion e to engage with the surface e between the arins of the rod c thereby
forcing the same down upon the die d, as will be evident.
Of course any other suitable mechanism may be used instead of the foot lever b
for operating the rod et, as, for instance, the lower end of said rod can be connected
with a crank on a shaft operated by steam power.
The chute for feeding the lacing studs or staples successively beneath the
punching rode is preferably made from a piece of sheet metal, which is bent as
shown more especially in Figure 14, being provided with parallel sliding edges or
ways upon which the plates of the lacing study are arranged so that the
prongs project down between the two sides of the chute while the staple

page_text: portion and the pulley project above said ways f¹ as clearly illustrated in Figures 1
and 4. Said chute is provided with the downwardly projecting end portions f
connected by stiffening bar f suitably arranged therebetween, which causes said
ways to retain their proper positions in relation to each other. A suitable
opening is formed in said portions f2, whereby the chute can be arranged on
a projection formed on the lower end of a lever h which is provided at its upper
end with an eye for pivotally attaching said lever to the upright A, as will be
seen from Figures 1, 2, et sequeter.
From said projection extends a cylindrical arm ³ on which is arranged a
suitable link i, secured thereto by means of a nut working on a threaded portion *,
extending from said arm . The upper end of said rod is pivotally attached by
means of an eye to a pin on the lever e.
As will be seen from Figures 1, 4, and 5, and as also indicated in dotted lines in
Figures 13 and 15. said chute may be provided with a suitable covering * formed
integral with the sides of the chute or soldered or secured thereto in any well-
known manner, which acts as a guard and prevents the lacing studs or staples from
being displaced from the ways when said chute has been tilted.
As will be clearly seen from Figures 2, 6, 7, 8, 9, and 10, the lower portion of
the rod is provided with a recess or cavity e, which conforms in outline to the
shape of the lacing stud, thereby allowing the staple portion and its pulley to be
inserted into said cavity, when the chute is in the position indicated in Figure 1.
The means for holding the stud or staple in said cavity c' consists of a spring arm j,
suitably secured to the lower portion of the rod c, being provided with a spring,
which normally projects into a slot or perforation, communicating with said
recess, and thereby holds said staple portion within said cavity, as indicated in
Figure 9.
I contemplate using with this machine a lacing stud or staple holding galley k,
which is similar in construction to the chute, being provided with ways k¹ and a
suitable formed guard ².
At the forward end of said galley k, the same is provided with a tongue ³ which
can be inserted into a slot in the portions of the chute f and thereby held in
position therein, as indicated in Figures 1, 4, and 5.
A. peculiarly bent spring projects in front of the ways of the galley k, as
indicated in Figure 18. This spring is attached to one side of said galley k by
means of a pin or rivet . Said galley can be filled at its upper end with any
desirable number of lacing studs or staples, the bent spring preventing the
displacement of any of such studs or staples. When the tongue is being
inserted into the perforation in the chute / said spring k is forced to one
side of said chute, as clearly indicated in Figure 3, and an unobstructed passage-
way is thereby formed between the galley and said chute for the sliding down of
the staples into position beneath the rod c.
The mode of operation of the above described devices for inserting the lacing
studs or staples through the shoe-upper, and bending down the prongs thereof is
after the following manner:
The galley, which has previously been filled with lacing studs or staples is
attached to the end of the chute f, in the manner just above described, or in any
other well known manner.
The mechanism is caused to assume the position indicated in Figure 5, whereby
the studs or staples are caused to slide down upon the ways fl of the chute f
until the forward stud or staple reaches the curved end of the chute.
The coiled spring, while the mechanism is in this position, is compressed, and
as soon as the power is taken from the rod et, said spring causes the return of the
rod c to the position indicated in Figure 1.
At the same time the lever e assumes its normal position, and by means of the
intermediately placed link and the lever h, said chute fand the galley are
brought in the position-shown in Figure 1, causing the forward end or nose por-
tion of the chute to project directly beneath the lower recessed end of the

page_text: rod c, while the staple portion of the forward stud comes in contact with the
rounded end of the spring actuated pin (see Figure 10) forcing the latter out
and allowing the insertion of the staple portion and its tubular eye or pulley into
the recess or cavity e, where it is held by the action of the pin which has
been immediately returned to its normal position by the spring j, as indicated in
Figure 9.
In order to attach the lacing stud or staple to the shoe upper, the latter is
placed upon the upper surface of the die d, and by means of the foot lever, or
other suitable power, the rod e causes the lever to swing upon its fulcruunal
supports A whereby the chute becomes tilted, as indicated in Figure 4, leaving
the lacing stud or staple, which is held by the spring actuated pin j', depending
from the recess or cavity e' in the bottom of the rod c. By this time the nose
portion of the lever e engages with the surface, between the arms c², on the
rod c, which moves downwardly in the perforated arms or sleeves a and a', the
chute at the same time moving still further out of the way, until the prongs of
the stud or staple are forced through the upper and come in contact with the
inclined portions of the cavities in the die . The inclined portions cause said
prongs to be spread outwardly until their ends reach the inclined portions in the
same cavities, which cause the ends to be slightly turned upwards and into the back
of the shoe upper, so that they will not project therefrom and thereby be apt to
tear the wearer's stocking. When the stud or staple has thus been clinched, the
spring causes the return of the several parts of the mechanism to their normal
positions indicated in Figure 1, whereby another stud or staple is inserted in the
cavity and the operation of attaching the same to the shoe upper can be repeated.
In this manner, the studs or staples are automatically inserted and held in place
in the recessed end of the rod c, and then firmly secured by means of said rod and
the die to the shoe upper, until the lacing studs contained in the galley k have
been exhausted, when the empty galley can be removed from the chute fand a filled
one inserted in its position.
One form of mechanism for producing the reciprocatory movement of the rod et
is illustrated in Figure 1, but not described herein, not being considered essential
to an understanding of that portion of the machine, it being my intention to employ
any other well known means for operating said rod e".
It will be understood that many variations of construction of the various parts
herein described may be made. For instance instead of soldering or otherwise
securing the guards or coverings to the chute and the galleys k, said part
can be formed integral with the sides of the chute, or, said coverings may be
entirely dispensed with.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
