PROVISIONAL SPECIFICATION.
An Improvement in Horse Shoes.
I, JAMES MCHARRIE, of Charlotte Street, Stranraer, Wigtownshire, Ironmonger,
do hereby declare the nature of this invention to be as follows:-
This invention relates to horse-shoes and it has for its object to so make the shoe
that the hoof, when treading, can spread laterally.
In carrying out my invention, I make the shoe of the usual shape, but the nail
holes are dove-tailed or tapered and open at the outside, that is to say they are cut
away so as to allow the heads of the nails, when the hoof is expanded, to move
outwards, i.e. laterally in the holes. The tapered shape of the holes, prevents the
shoe falling off. The nails at the toe of the sboe, may pass through holes in the
usual manner.
A horse-shoe, made as herein before described, allows the hoof to expand
naturally and it also prevents, or aids in the prevention, of contraction and
concussion. Whilst giving the necessary protection to the foot, the improved shoe
gives a much greater freedom of action than those generally in use.
Dated this 1st day of March 1892.

COMPLETE SPECIFICATION.
An Improvement in Horse Shoes.
I, JAMES MCHARRIE, of Charlotte Street, Stranraer, Wigtownshire, Ironmonger,
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 horse shoes and it has for its object to so make the shoe
that the hoof, when treading, can spread laterally.
In carrying out my invention, I make the shoe of the usual shape, but the nail
holes are dove-tailed or tapered and open at the outside, that is to say they are cut
away so as to allow the heads of the nails, when the hoof is expanded to move
outwards, i.e. laterally in the holes. The tapered shape of the holes, prevents the
shoe falling off. The nails at the toe of the shoe, may pass through holes in the
usual manner.
A horse-shoe made as herein before described, allows the hoof to expand
naturally and it also prevents, or aids in the prevention, of contraction and
concussion. Whilst giving the necessary protection to the foot, the improved shoe
gives a much greater freedom of action than those generally in use.
And in order that my said invention may be properly understood, I have
hereunto appended an explanatory sheet of drawings, whereon
Fig. 1 is a plan view of the shoe.
Fig. 2 is a side view.
Fig. 3 is a plan view of a slightly altered shoe.
Figs. 4 and 5 are enlarged detail views.
Referring to the drawings:-
The shoe a which may otherwise be of the ordinary shape and make has nail
holes which, as shown, are open at the side, i.e. the holes appear as recesses or
cuts made in the shoe. The holes bare tapered or narrowed towards their under-
side so as to, when the shoe is fitted in place, grip the tapered heads of the nails

on the drawings. The position of the nail d, in the hole b, is shown clearly at
Fig. 4. Four holes are shown, although there may be six or other number. The
front or "toe" holes e are preferably made of the usual form.
In Fig. 4 the dotted lines indicate the sideward travel of the nail d, in the hole b,
due to the lateral expansion or spread of the hoof when the horse sets its foot
down.
at c.
In Fig. 3 the holes are made dove-tail shape and are also tapered vertically
When the holes are made dove-tail-shape the nail d, in its lateral travel due
to the spread of the hoof, is prevented from coming right out of the hole or
recess as the opening is made sufficiently narrow to prevent the passage
outwards of the nail. Instead, however, of dovetailing the holes b, two small
projections or a bridge piece, or its equivalent, may be made or left across the
opening for this purpose.
The improved shoe allows the hoof to have a natural and healthy action when
the horse is running.
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 :-
A horse-shoe made with nail holes (or their equivalent) substantially as
hereinbefore described with reference to the drawings annexed and for the
purpose of allowing the horse's hoof to have a natural and healthy action when
running.
