page_text: I, CHARLES WALDRON HAYES, residing at 812, Thirteenth Street, N.W. Wash-
ington, in the District of Columbia, and United States of America, gentleman 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 has reference to horseshoes and consists in the improvements and
features of construction hereinafter described and set forth.
The object of the invention is, more particularly to provide a shoe and devices
for connecting the same to the hoof, that the shoe may be quickly and firmly.
secured in position on the hoof without the use of nails or other permanent
fasteninge, the said shoe being adapted to be as quickly removed when desired.
Numerous objections are incident to the prevailing manner of shoeing and for
many purposes the common form of shoe is unsatisfactory. Among such objec-
tions and disadvantages may be noted the fact that the shoes are secured perina-
nently to the foot, for an extended period, and are generally not removed. and
renewed until they are considerably worn away.
Then, again a large number of nails are used from which considerable danger
ensues from being driven carelessly into the tender parts of the foot; and when
such shoes are removed, they are generally taken off, so as to withdraw the nails at
the same time. Before, however, the shoes and nails can be so removed, it is
necessary for the smith to straighten the clinched ends of the nails after which
operation, the nails are mostly irregular to some slight degree, which causes them
to tear their openings when withdrawn. As a consequence the nail openings in
the wall or crust of the hoof, become so numerous and large, that it is impossible'
to secure a firm bearing for the nails of the succeeding shoe..
The wear of the shoes of many horses is occasioned for the most part by their'
stamping or pawing in their stalls, rather than from actual service. Further,
the permanently attached shoes subject the foot, when the horse is stalled, to
the same unresisting and rigid strain, experienced during working hours, and con-
sequently, no provision is made for allowing the hoof a healthy expansion and rest,
when the horse is not in service.

page_text: By my invention all of the foregoing objections and disadvantages are obviated,
whilst an effective shoe is provided at but a slight if any, increase in the expense
of the shoe.
In the accompanying drawings forming part of this specification.

applied thereto.

of the fastening plates.
Fig. 3 is a perspective view of the upper side of the shoe.

Figs. 5 and 6 are perspective views of the side and toe plates.
Fig. 7 is a transverse section of Fig. 5 andr
Fig. 8 is a perspective view illustrating the construction of the toe clamps.
In order to convey a clear understanding of the invention, the description will
be first confined to the construction and arrangement of the fastening plates, and
then with respect to the shoe proper.
The under face of the wall or crust of the hoof, at the point known as the
quarters, is provided with a recess at each side, each of which recesses, is of such
depth and shape as to adapt it to snugly receive and contain one of the plates A,
which, as seen in Fig. 2, contracts, toward the center of the foot. Each of the said
plates, A, is provided with a central opening, a, which is countersunk on the bottom
face of said plate. At either side of the opening, a, are arranged holes, b, b,
through which nails are driven to firmly secure the plate to the wall or crust. On
the outer edge face of each plate A, and extending from one end to slightly
beyond the center of such edge, is a longitudinal depression, the inner end of which
is intersected by a conical opening, a', which also communicates with the opening, a.
Within the said depression is located a spring, a², which is secured at its outer
end by a rivet, whilst its inner end carries a conical pin, a³, which plays through
the opening, a¹, and transversely across the opening, a.
B refers to a plate which is to be located at the toe of the hoof, and is secured
thereat in a recess therein by nails, substantially the same as the plates, A. The
plate, B, however in addition to its nail holes, is provided with two horizontal
openings, b¹, 61, as shown most clearly in Figs. 4 and 6.
The shoe, C, which may be of any preferred form is provided at each side, at
the point which registers with the plates AA, with an upwardly projecting lug, c
(Fig. 3) which lug is of conical form and adapted to enter the opening, a, in the
plate A. Each lug, c, has an opening c³, passing horizontally through the same.
The shoe C, is recessed on its underside at the toe, for the reception of the
horizontal portion or base, D, of a toe clamp E, Figs. 4 and 8, the said base, D,
being provided with two openings d, d, through which pass screws to secure the
clamp, E, rigidly to the shoe. It will be noted by reference to Fig. 1, that the
base D, is Bush with the underface of the shoe.
Extending rearwardly from the curved portion E¹³, of the toe clamp are two
horizontal pins, e, e. In practice, the toe clamp E, is secured to the shoe as before
explained, and the shoe manipulated so that the pins, e, e, enter the openings, b¹, b₁,
to permit the curved part E', to bear firmly against the front or toe portion of
the hoof The shoe is then forced up against the bearing on the underside of the
wall or crust, thereby causing the lugs, c to enter the openings b', 6', in the plates A,
the conical form of said lugs resulting in pushing aside the pins, a³, until the
openings in said lugs come opposite the openings, a¹, in the plates, when the
springs, a², project the pins, as, through the openings in the lugs and lock the latter
with the shoe firmly to the hoof.
It will be noted that the length of the pins, e, e, is relatively much greater
than that of the other pins and parts, but this is amply provided for from the fact
that the wall or crust of the hoof is greatest both in thickness and in height
at the toe of the hoof, consequently a greater bearing is afforded for the fastening
devices at such point, which is the place where the greatest strain is received.

page_text: Moreover, the strain or tension on the shoe is received by the latter in sub-
stantially horizontal direction thus serving in my arrangement, to more effectively
hold the plates and shoe together, which would not be the case, if the power or
force was in a vertical direction. In the latter event the effect would be to tear
or rend the shoe from the plates A A and B.
When it is desired to remove the shoe it will only be necessary to insert some
pointed instrument or piece of metal under the springs, a², so as to lift or move
their free ends out of their recesses, causing the pins, a³, to be withdrawn from the
lugs and then finally disengaging the toe clamps from the plate B.
As the natural tendency of the wall or crust is to grow laterally, it will be only
necessary to occasionally rasp the outer face of the crust in order to preserve the
outer edge of the plates flush with said crust.
Some of the advantages incident to my invention may be noted as follows.
The foot can be permitted to expand whenever desirable.
The shoes can be quickly applied and removed. They can be interchanged
whenever necessary so as to substitute rough shoes suitable for bad weather or a
light or heavy shoe, and by the occasional removal of the shoes, accumulations of
foreign matter between the shoe and hoof will be guarded against.
I do not limit myself to the precise construction of fastening devices described,
as the same may be subject to modification and change without departing from the
spirit of my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. The combination with a horseshoe provided with projections, of plates adapted
to be secured to the underside of the foot to engage said projections, substantially
as set forth.
2. The combination with a horseshoe provided with projections, as described, of
plates adapted to be secured to the underside of the foot, openings in said plates
to engage said projections, and a locking device for securing said projections in said

tions as described, of plates adapted to be secured to the underside of the foot,
