I, WILLIAM ENOS SHAW, of the City and County of San Francisco, State of
California, No. 1,619, Market Street, Carriage Manufacturer, do hereby declare the
nature of this invention to be as follows:-
My present invention has for its objects to provide a simple, durable, compact,
and comparatively inexpensive and light shoe, by the use of which the speed and
general action of the horse is benefited, while slipping and shock from concussion
18 obviated.
The main portion of the shoe including the toe, heel, quarters clip and fuller-
ing for nails are formed as in the ordinary metal shoe.
Leading backward from the toe of the shoe and equidistant from opposite legs
thereof is a central spring web which extends slightly beyond the heels of the
shoe. The plane of this web is not coincident with the plane of the shoe but
intersects it in the neighborhood of the. toe.
It is manifest that as the shod hoof strikes the ground, the rear extremity of
the web will come in contact with the ground first, and its springy yielding
nature will prevent any sudden concussion to the animal, but on the contrary,
let the hoof down gradually as the weight of the horse overcomes the spring in
the web and causes it to occupy approximately the same plane as that of the shoe
proper. It suffices merely to mention that in forcing this web down, it comes in
contact with the frog and produces a most desirable pressure.
As a means for increasing the foot hold of the shoe, I have provided a cup
shaped member into the cavity of which is molded under pressure, a sufficient
body of rubber.
The manner of securing. this member to the outer extremity of the web con-
sists in causing the opposite edges of the web to diverge as they advance from
the toe, while a dove-tailed groove in the under surface of the member engages
with this. wedge shaped web.
The web can be either welded to the shoe or a dove-tailed groove may be
formed in the toe of the shoe to receive a correspondingly formed portion of the
web..
It is manifest that the use of my shoe relieves the foot with "low heels" and
obviates the inclination of the pastern which fatigues the tendons.
:
I have practically demonstrated by actual trial, that by use of my shoe animals
previously suffering from contraction or knee sprung are absolutely cured, while
he perceptible improvement in the beauty of gait of the horse is worthy of especial
nention.

page_text: I, WILLIAM ENOS SHAW, Carriage Manufacturer, of 1,619, Market Street, City
and County of San Francisco, State of California, in the United States of America,
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:-
-.
The prime objects of my present invention are to provide a simple, durable,
compact, comparatively inexpensive and light horse-shoe, by the use of which the
speed and general action of the horse is benefited, while slipping and shock from
concussion is obviated.
A further object of my invention is to produce such a pressure on the frog of
the shod horse, as would naturally be felt were the horse's hoof in its free, uncon-
fined, natural state. This frog is of extreme importance in considering the after
effects of shoeing, and with this experience I have formed my shoe to meet such
requirements.
As the weight of the animal brings the shoe down against the ground, the
parts act as a lock which is especially valuable where a secure foot-hold is desired.
In the accompanying drawings:-
Figure 1 is a view of a horse's leg, with my shoe positioned on the hoof. The
hoof is shown resting flat on the ground.
Figure 2 is a similar view with the hoof raised.
Figure 3 is a top view of the shoe.
Figure 4 is a section through the line x x Figure 3..
Figure 5 is a section through line yy.
Figure 6 is a view of a modification.
Figure 7 is a section on line AA, Figure 6.
Figure 8 is a section on line B B.
Figure 9 is a modification.
Figure 10 is a view of a modification.
1 represents the main portion of the shoe, from the toe of which, and equi-
distant from opposite legs 2, 2, leads backward the spring web 3, which extends
slightly beyond the heels of the shoe. The plane of this web 3 is not coincident
with the plane of the shoe proper, but intersects it in the neighborhood of the
toe.
it is manifest that as the web comes in contact with the ground first, any
sudden concussion of the animal is prevented, while a most desirable frog pressure.
is produced.
As a means for increasing the foot-hold, I have provided the cup-shaped
member 4, into the cavity of which is moulded under pressure a body of rubber.
The central shank 5 is to hold the rubber within the cavity..
The opposite edges of the web 3 diverge as they advance from the toe, while
the dove-tailed groove in the underside of the member 4 engages with the web.
The lip 6 enters a corresponding cavity 7 in member 4.
The screw 8 which passes through the lug 9. holds member 4 in place, and can
be removed at will for re-placing.
This member 4 can also be used on the heels and toe of ordinary shoes..
In order to make the web detachable, I have provided the means shown in
Figures 6 and 10, which consists in forcing a tapered end of the web into a dove-
tailed groove in the toe or a projection 11 thereof. Screw 12 prevents acci-
dental withdrawal of the web. In Figure 9 the spring is formed of a series of
leaves, similar to a wagon spring.

page_text: In Figure 10 the dove-tail in the projection 11 diverges from the toe back-
ward and the spring is forced inward from the front. The split or groove 13
allows the spring to yield as it is driven home thereby binding it securely in
place, which does away with the screw 12, shown in Figure 6.
I have practically demonstrated that by the use of my shoe animals previously
suffering from contraction or knee sprung are absolutely cured, while the percep-
tible improvement in the beauty of gait of the horse is worthy of especial mention.
I wish to protect myself in the matter of mechanical equivalents.
Having now particularly described & 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-In combination with a horse-shoe, a spring web formed independent of said
shoe and a tapered dove-tailed groove in said shoe adapted to receive one ex-
tremity of said web, for the purpose set forth.
2-A horse-shoe provided with a central spring web, and a non-slipping surface
formed independent thereof but secured to said web and adapted to come in
direct contact with the ground, for the purpose set forth.
3-A horse-shoe provided with an independently formed central spring web, a
non-slipping surface removably secured to said web, said shoe being widened
at its point of union with said web, for the purpose set forth.
4-A non-slipping member for horse-shoes adapted for contact with the ground
or pavement, consisting of an outer shell having an inwardly flaring mouth, an
inner body of rubber moulded within said shell, a headed pin within said shell
and a cavity in the underside of said shell, substantially as set forth.
5-In combination with an ordinarily formed horse-shoe, of a central spring
web leading backward from the toe, and at an angle with the plane of the legs
of the shoe, for the purpose set forth.
