Complete Specification Left, 6th July, 1892-Accepted, 6th Aug., 1892.
PROVISIONAL SPECIFICATION.
Improvements in Horse-shoes.
I, ALFRED WILLIAM KNIGHT, of Cuckfield, in the County of Sussex, Engineer,
do hereby declare the nature of this invention to be as follows :-
This invention relates to what I call a compound horse-shoe for the purpose of
preventing concussion and slipping.
According to my invention I form a skeleton or open metal frame or frames
into and around which I place a suitable elastic or yielding material such as india-
rubber, and I then attach the whole by suitable means such as cement and studs
to the bottom surface of a horse shoe, holes being left in the said material for
the reception of the usual nails for attaching the compound shoe to the animal's
hoof.
My invention is particularly applicable to horse-shoes, having roughing studs or
calks, such for example as those described in the Specification of, my, former
application No. 1266 of 1891. In this case. the elastic or yielding, material also
surrounds the said studs which serve to assist in holding the said material in place
and decrease the wear of the same.
Instead of employing a skeleton frame or frames as hereinbefore described I
may use wire gauze or other suitable substance which will give the.elastic or yielding
material the required rigidity.

COMPLETE SPECIFICATION.
Improvements in Horse-shoes.
I, ALFRED WILLIAM KNIGHT, of Cuckfield, in the County of Sussex, Engineer,
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:-
This invention relates to what I call a compound horse-shoe for the purpose. of
preventing concussion and slipping.
According to my invention I form a solid or a skeleton or open metal frame-or
frames, in conjunction with which I use a cushion of suitable elastic or yielding
material such as india-rubber, and I then place this cushioned frame in a channel
in the bottom of the shoe, secure it therein by cement or by closing in the walls
of the channel.
My invention is particularly applicable to horse shoes having roughing studs.or
calks, such for example as those described in the Specification of my former
application No. 1266 of 1891. In this case the elastic or yielding material also
surrounds the said studs which serve to assist in holding the said material in place
and decrease the wear of the same.
Instead of employing a solid or skeleton frame or frames--as hereinbefore
described I may use wire gauze or other suitable substance which will-givo the
elastic or yielding material the required rigidity.
To enable my invention, to be fully understood I will describe the same, by
reference.to the accompanying drawing, in which:.
Figure 1 is a view of the underside of a horse-shoe, constructed according to my
invention, for the off fore foot of a horse:

page_text: Figures 2, 3 and 4 are sections on the lines z z, y y and = z respectively of
Figure 1:
Figure 5 is an underside view of a part of the skeleton metal frame; and,
Figure 6 is a longitudinal section of the same:
Figures 7 and 8 are an underside view and side elevation hereinafter described.
Similar letters of reference indicate corresponding parts in all the figures.
a indicates the shoe proper which is provided with the ordinary nail-holes b, b
and with the creases c, c and in the bottom face of which is formed a groove or
channel d corresponding approximately with the shape of the shoe, as indicated
most clearly by the dotted lines in Figure 1.
e indicates the metal frame adapted to fit into the groove d and f is the india-
rubber or other suitable cushioning material with which the said frame is provided
on the top and bottom faces, that part of the india-rubber upon the top face and
which is indicated by the letter g in Figures 2, 3 and 4, serving as a cushion between
the skeleton frame and the shoe proper and that upon which is on the bottom of
the shoe and which is indicated by the letter h, Figures 2, 3 and 4, serving to
deaden the concussion between the shoe and the ground.
In practice I prefer that the india-rubber facings upon the frame should be
vulcanized thereon, and in this case I form through the frame a series of
openings i, i which, when the plastic india-rubber is applied, before vulcanization,
become filled with india-rubber, as shewn in Figures 2 and 3, so that the india-
rubber upon the opposite faces of this skeleton frame is practically all in one piece.
Instead of vulcanizing the india-rubber upon the shoe I may apply loose pieces of
india-rubber or other suitable flexible material of the required shape by means of
cement, and in cases where the frame is fixed in the shoe by closing in the walls
of the channel the cement is unnecessary upon the cushion g.
In order to prevent the india-rubber upon the wearing face of the shoe from
becoming worn too quickly and at the same time to afford a firm grip for the horse
I advantageously form upon the said frame a series of projections j, j, Figures 5
and 6, the height of which corresponds with the thickness of india-rubber to be
applied, as will be readily understood by reference to Figure 2.
It is to be understood that when my frame is to be used in conjunction with the
removable studs of the kind described in the Specification of my former application
.No. 1266 of 1891 suitable holes will be formed in the said frame to receive the
said studs.
The india-rubber facing 9 is made of the same size as the groove d in the shoe
but the facing his made wider than the frame e so that on the inner side of the
shoe it will extend to the edge thereof and on the outer edge so that it will extend
nearly up to the creases c, c and at the heel portions to the outside edge of the
shoe, as clearly shewn in Figure 1.
When my invention is applied to hind shoes the calks or heels k are formed upon
the frame e, as shewn in Figures 7 and 8, and in some cases I may dispense with
the outer cushion h so that the said frame remains uncovered. I advantageously
form the calks with grooves also as shewn in Figures 7 and 8 to afford a firmer
grip than is afforded with plain calks.
The shoe represented in the drawing is supposed to be made of malleable metal
and the ends of the channel d made solid, that is to say, the walls of the groove
are continued round the heels, as indicated. In this case I form in one side of
the shoe a notch m through which a tool may be introduced to prise the frame e
out of the channel. When my shoe is made of wrought metal, in which case the
grooved would be rolled therein, this notch is unnecessary as the ends of the
channel are open as indicated by the dotted line n, n Figure 1.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A horse-shoe having formed in its under side a channel adapted to receive a

page_text: frame and a cushion of india-rubber or other elastic or yielding material between
the said frame and the shoo, all substantially as described.
2. A horse-shoe having a channel formed therein adapted to receive a frame,
the upper
and under sides of which are faced with india-rubber, substantially as
¡ described.
3. The manufacture and use of horse-shoes constructed substantially in the
manner hereinbefore described and illustrated in the accompanying drawing.
