PROVISIONAL SPECIFICATION.
An Improved Horse-shoe.
I, WILLIAM TORY, of Guysborough, Nova Scotia, Canada, Gentleman, do
hereby declare the nature of this invention to be as follows:-
The special object of this invention is to make a horse shoe which is capable of
spreading the hoofs of horses, and thereby relieve the inconvenience to the animals
occasioned by contracted feet.
By this my invention I form a horse shoe which in shape is approximately the
same as the ordinary shoe. In construction, however, the shoe is made in two
parts which are pivoted together at their most forward point, thus forming two side
pieces which are capable of swinging horizontally around the pivot-pin. A two-
armed spring is secured upon the pivot-pin in such manner that it tends to press
the two side pieces of the shoe outwardly. When the shoe is nailed to the hoof of
the horse the tendency of the spring is to diverge the two portions of the shoe
and the hoofs to which they are secured.

COMPLETE SPECIFICATION.
An Improved Horse-shoe.
I, WILLIAM TORY, of Guysborough, Nova Scotia, Canada, Inventor, 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 special object of the invention is to make a hoof and shoe spreader for
horses whereby contracted feet may be relieved and cured.
The invention will first be described in connection with the drawings, and then
pointed out in the claim.
Figure 1 of the drawings is a perspective view, Fig. 2 a plan view, and Fig. 3 a
median longitudinal vertical section.
In the drawings I show a shoe of the usual shape, but made in three pieces A
BA, connected by the two pivots a a. The sides A A are provided with five
nail-holes a¹, by which they may be nailed to the hoof. Two of these holes are
made very near the rear ends or heels of the side pieces, so as to give the expanding-
spring C greater power over the hoof and adapt the strength of spring to the
requirements of the hoof for its expansion.
make the toe-calk D, hinge-plates E, and clip F, which taken together con-
stitute the piece B, all in one piece and so arrange them as to cover the opposing
ends of the pieces A A. The plates E are placed one above the other and con-
nected by the two hinge bolts or pivots a a.
In the central shoe-section B, between the two plates E E, I secure the two-
armed spring C by means of a bolt G, screwed through the upper plate directly
over the middle of the toc-calk and through the middle of the spring. Each prong
or arm of the spring presses against one side A of the shoc, so as to tend to throw
the heels outwardly.
The clip F fits over the end of the hoof in order to secure the front part of the
shoe more firmly to the animal's hoof, the nails being set back to free the hinge-
joint.

page_text: The plates are so shaped where they approach the convex and concave edges
of the shoe as to prevent clay or other substances from getting into the joints.
The recess or open space between the front ends of the sides of the shoe and the
plates E E is for the reception of the expanding-spring, one of whose legs bears
against the end of each shoe side. The spring is pivoted at its notch or nearly
middle or quite in line with the pivots of the shoe sides. If the plates E E,
calk D, and clip F were in separate pieces jointed together, the impact of travel
would soon loosen some of these joints and the shoe sides would not work properly
on their pivots. The plates E E are shaped so as to cover the spring and space
between the pivoted ends of the shoe sides, so as to effectually prevent clay, sand,
grit, or other matter from getting between the jointed ends of the shoe and the
plates. It will be perceived that the upper plate E carries the clip F, while the
lower plate E has the calks D, making solid where the impact and wear come.
The plates and calk being in one piece, the hinge joint is a very strong one,
while the toe-calk is also strengthened, as the horse's weight on the upper plate
binds the joints together, while perfect freedom of action is left to the hind-joints
and to the spring.
In the event of a very thin hoof where the pressure of the spring will be too
great, the last nail at each heel of the sides A may be omitted or withdrawn. By
this means the pressure may be always adapted to the requirements of the hoof.
It will be observed that the integrally-connected plates E E cover the joints of the
shoe at top, bottom, and rear, while the calk and clip form a close joint in front of
the shoe.
I am aware that it is not new to divide a horseshoe in front and then pivot them
(the parts) together on a lap-joint or to an intermediate piece, also to use a two-
pronged spring pressing outwardly on the inside of the shoe.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
The plates E E, integrally connected at the rear and provided in front with the
calk D and clip F, in combination with the two pivoted sections A A and the two-
armed spring C, the latter held by a pivot G in the space between the plates E E
and sections A. A, substantially as shown and described.
