PROVISIONAL SPECIFICATION left by the said John Edmund Jarvis at the

Surgeon, M.R.C.V.S. "IMPROVEMENTS IN HORSE-SHOES.'
shaped
My Invention relates to improvements in adapting elastic pads to horse-shoes, in
order to obtain a more secure foothold on slippery surfaces; and the Invention
consists in securing a pad or strip of india-rubber in a recess in the face or tread of
the shoe, formed either by flanges turned down at right angles; and extending
entirely around the inner and outer edges of the shoe, thus forming a
groove in cross section for the india-rubber strip to lie in, the strip being in this
case secured by studs or otherwise, or instead of an inner flange being formed on
the shoe a loose rim extending round the inner edge of the shoe in the same way as
the flange may be used, the said rim being secured to the plate of the shoe by
screws, and by its ends being received in holes in the outer flange at the heel of the
shoe. This loose rim serves to clamp the india-rubber strip to the shoe by a flange
with which the strip is provided, the strip in this case being made of
in cross
section. In either case the outer flange is notched where the nail holes occur to
allow of the nails being inserted without passing through the india-rubber pad,
which is inserted and secured before the shoe is applied. The strip or pad is of
such thickness as to project from the groove and come in contact with the ground,
and by its adhesion prevent slipping.

JOHN EDMUND JARVIS, of Knightsbridge, in the County of Middlesex, Veterinary
Surgeon, M.R.C.V.S. "IMPROVEMENTS IN HORSE-SHOES."
My Invention relates to improvements in adapting elastic pads to horse-shoes, in
order to obtain a more secure foothold on slippery surfaces; and the Invention
consists in securing a pad or strip of india-rubber (or it might be leather) in a
groove or recess in the ground surface of the shoe, formed by flanges or rims at the
inner and outer edges of the shoe, the elastic pad being secured therein by screws or
rivets, or instead of the inner rim being formed on the shoe a loose rim may be
employed to clamp the india-rubber strip to the shoe, the rim being secured and the
pad formed, as hereafter more fully described. In either case the outer rim is
notched where the nail holes occur to form calks to improve the foothold, and allow
of the nails being inserted without passing through the pad, which is secured to the
shoe before the latter is applied to the hoof. The clastic strip or pad is of such
thickness as to project beyond the rims, and by its adhesion on the ground prevent
slipping on smooth surfaces.
In order that my Invention may be more readily understood, I will proceed to
describe it in detail, with reference to the accompanying Drawings, in which
Figure 1 shows a face view, and Figure 2 a cross section of a shoe forged with
a rim at the inner and outer edges to form a groove for the reception of the
pad.
A, B, are the inner and outer rims; and C is the pad, made preferably of
vulcanized india-rubber, and of such thickness as to project slightly beyond the
rims, so as to come first into contact with the ground. The pad is secured to the
shoe by countersunk screws or rivets D. The outer rim A is notched at a, a, a,
leaving projections or calks to increase the foothold, and the nail holes are in these
notches, as shown. In making shoes of this description they would be rolled in the
form of straight bars, with the rims and notches, and afterwards bent to the horse-
shoe form.
Figure 3 shows a face view, and Figure 4 a cross section, on line 1-1, Figure 3,
of a shoe, in which the inner rim B is removable, and secured to the shoe by
countersunk screws at the heel, and by a lug or catch b formed on said rim, and
engaging in a recess in the upper surface of the shoe, near the toe, as shown. The
outer. rim is notched as before. This construction is especially designed for horses
that wear their shoes at the toe only. In this case the pad is made of india-rubber,
and of the form shown in cross section in Figure 5, in which C represents the pad,
and c a web of india-rubber covered fabric,. by which the pad is clamped to the
shoe by the rim B, as shown in Figures 3 and 4.
In the shoe shown in face view in Figure 6 the same form of pad is used, but the
inner rim is secured by a screw at the toe, and at the heel by the ends of the rim
being received in holes in the outer rim A, which is continued round the heels of
the shoe as shown.
One great advantage of these shoes is that they may be used with or without the
pads, as desired.
Having described the nature of the said Invention, and the manner of performing
the same, I declare that what I claim as the Invention to be protected by the
herein-before in part recited Letters Patent is,-
1st. A horse-shoe with inner and outer rims as described to form a groove for
the reception of an elastic pad, as shown and described:
2nd. The combination with a horse-shoe formed with rims, or provided with one

page_text: fixed and one loose rim, as specified, of an elastic pad applied and secured, as and
for the purpose set forth.
In witness whereof, I, the said John Edmund Jarvis, have hereunto set my
hand and seal, this Twenty-sixth day of May, in the year of our Lord One
thousand eight hundred and seventy-seven.
