COMPLETE SPECIFICATION.
Improvements in Lacing-studs for Boots and 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 Newark, residing at 184 South
6th Street, in the County of Essex, and State of New Jersey, United States
of America, Shoe Manufacturer, do hereby declare the nature of our invention,
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
The present invention relates more especially to improvements in lacing-studs of
that class provided with a forwardly projecting head or face-plate, and the object
of the invention is to provide a stud adapted to be secured near the meeting edges
of the shoe-upper having a revolving pulley or sheave and the lacing cord so
arranged, that, after the foot has been placed within the shoc, it can be firmly
laced by means of one pull on the ends of the lacing-cord and the meeting edges of
the upper thereby brought down on the front of the foot.
The invention consists of certain arrangements and combinations of parts as will
be hereinafter more fully described and finally embodied in the clauses of the
claim.
In the accompanying sheet of drawings, in which similar letters of reference are
employed to indicate corresponding parts in each of the several views,-
Figure is a perspective view of a shoe provided with lacing studs embodying
our invention.
Figure 2 is an enlarged top view of one of the studs applied to the shoe-upper,
Figure 3 is a side view of the same, and Figure 4 is a horizontal section taken on
line in said Figure 3.
Figure 5 represents a blank of sheet metal from which the form of stud
illustrated in Figures 2, 3 and 4 has been struck up.
In Figure 6 are illustrated a number of differently constructed pulleys or sheaves,
being represented in side elevation and top view.
Figures 7 and 8 are a side view and a vertical section respectively of a cast stud
provided with a tubular post for attaching the stud to the shoe-upper, a pulley or
sheave being arranged thereon as shown.
Figures 9 and 10 are side elevations of modified forms of studs provided with
differently arranged posts for securing the parts together.
Figures 11 and 12 are a side view and a vertical section respectively of a stud
provided with an eye or hollow post for attaching, the stud to the shoe-upper, and a
pulley or sheave being arranged thereon as shown.
Referring to the drawings, a indicates the shoe-upper; b, b, the meeting
edges adapted to come together down the front of the foot; c indicates the lacing
studs which are applied to each of said meeting edges, and d is a lacing cord
arranged in said studs, as will be clearly seen from Figure 1.
The lacing studs may be of any shape and may be provided with different
kinds of means for attaching them to the shoe-upper, the different constructions
shown herein serving to illustrate some of the various methods of carrying out
our invention.
The stud illustrated in Figures 2, 3 and 4 is struck up from a blank of sheet
metal, shown in Figure 5, which consists of a body-portion provided with a
perforation or hole and oppositely extending arms or prongs c
From one
end of the body-portion projects a neck c, in which is formed a head or
face-plate e provided with a small hole c. By means of the proper tools said

page_text: blank is bent into the shape illustrated more especially in Figure 3, and the down-
wardly projecting prongs c³ are forced through the material of the shoe-upper and
firmly bent down upon the opposite side thereof.
Before the parts of the stud are closed down; a post or pin upon which rotates
a pulley or sheave e is inserted through the perforation in the body-portion c¹.
and when the face-plate or head c has been bent to project over and above the
body-portion e', then the small end of the post is forced into said hole c in the
head and the several parts are firmly riveted together.
Of course the pulley or sheave e may be cylindrical or it may be provided with
a concave surface e, or its cylindrical surface may be corrugated as at e¹and e³,
but we intend to use a pulley, the peripheral surface of which shall be polygonal,
a hexagon or octagon, as at e, being the preferred form. It has been practically
demonstrated by experiment that the polygonal form of pulley is better adapted for
this use, than a plain cylinder. Upon pulling upon the ends of the lacing cord, it
has been found that when a cylindrical pulley is used, the cords slip and the pulleys
will not rotate, caused by their small size, and hence the meeting edges can not be
properly pulled together, but in using a pulley of a polygonal outline this difficulty
has been successfully overcome, and the pulleys are at all times caused to rotate
owing to the contact of the cords with the rough surfaces of the pulleys and thereby
preventing the slipping and hence the meeting edges of the shoe-upper can be
closely brought together.
In Figures 7 and 8 is illustrated a slightly modified form of stud which is made
from cast metal, being provided with a tubular shank c' closed at the top at c, as
will be seen from Figure 8. Said closed top e is provided with a hole in which.
the pin or post is inserted, a pulley or sheave being arranged thereon and the
other end of said pin or post being secured in a perforation in the head or face-
plate, as will be understood from said figure.
Figure 9 is a view of a stud struck up from sheet metal in which the body-
portion of the stud is provided with two posts c, and to which a separately formed
head or face-plate can be secured.
Figure 10 is still another modified form of construction in which the body-
portion has but one post and the separately formed head or face-plate is provided
with a post co. The ends of these posts can be riveted in holes formed respectively
in the said body-portion and the said head or face-plate, and the parts comprising
the stud can be firmly riveted together, as will be evident.
In lieu of these above described constructions, the stud c may be formed as shown
in Figures 11 and 12, in which the shank c" on the body-portion is formed into an
eyelet by means of which the stud can be secured to the leather. A small
pro-
jection or lip c can be made to project from one side of the shank and provided
with a hole in which the post or pin with the pulley or sheave e is secured. The
other end of the post or pin is fastened in a hollow head in any well known manner,
either by passing through a hole therein and being riveted or by being soldered
thereto.
When the meeting edges of the shoe-upper have been spread apart, the foot can
readily be placed in the shoe and by pulling on the ends of the lacing cord all the
pulleys in the studs are operated at one time, bringing the meeting edges of
the shoe-upper together, and the ends of the cord can be secured at the top of the
shoe.
By releasing said ends of the cord, the shoe can be removed from the foot
by simply withdrawing the latter from between the meeting edges, as will be
evident.
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 :-
1. A lacing stud consisting of a body-portion provided with means for attaching-
the same to the

page_text: projecting above and over said body-portion, in combination, with a pulley of a
polygonal or rough peripheral surface, substantially as and for the purposes set
forth.
2. In a lacing stud, the combination, with a body-portion c, provided with
prongs and a head or face-plate arranged over and above said body-portion, of
a post or pin secured between said body-portion and head or face-plate, and a
pulley on said post or pin, all substantially as and for the purposes set forth.
3. In a lacing stud, the combination, with a body-portion e', provided with
prongs and a head or face-plate arranged over and above said body-portion, of a
post or pin secured between said body portion and head or face-plate, and a pulley
of a polygonal or rough peripheral surface on said pin or post, all arranged sub-
stantially as and for the purposes set forth.
4. A lacing stud provided with a pulley having a polygonal or roughened
peripheral surface, as and for the purposes set forth.
