PROVISIONAL SPECIFICATION.
Improvements in Horse Shoes.
We, HENRY MARTIN of 25 Almeric Road, Battersea Rise, in the County of
Surrey, Gentleman, and ERNEST HENRY WYLEB of 9 Stone Buildings, Lincoln's
Inn, in the County of Middlesex, Solicitor, do hereby declare the nature of our
Invention to be as follows:-
The present invention is an improvement on Henry Martin's Patent No. 17616,
dated 22nd December 1887 which describes a shoe formed with a double groove, in
one of which is fixed a strip of indiarubber which projects beyond the shoe so that
the tread of the horse is taken on the elastic strip. The strip of indiarubber,
caoutchouc or other elastic material was placed in a deep groove of circular section,
and the lower face of the strip was formed of circular section to fit into the groove
while the upper face was of square section, the strip being secured to the groove by
a suitable cement.
We have found in practice that in hot weather the cement becomes more or less
plastic and the strip of rubber is consequently loosened; to obviate this defect we
have devised means whereby if necessary the rubber can be fixed in the groove
without the application of cement, but we reserve to ourselves the right of using a
small quantity of cement if found desirable.
In the Patent above referred to it was stated that the shoes would preferably be
made of wrought iron, but we have found steel more suitable to our purpose, and
our improvements consist in forming the groove for retaining the rubber strip of
square instead of circular section; and by this arrangement the face of the rubber
strip is reversed, that is to say, the square section of the rubber fits into the square
groove, while the circular section now becomes the face on which the tread of the
horse is taken. The sides forming the groove in which the rubber strip is placed
are turned over the rubber by any suitable tool and thus form a dovetail groove out
of which it will be impossible for the rubber to work loose.
The rubber strip will last as long as the shoe, and although its surface will wear
down in course of time, the shoe will prove efficacious so long as the rubber
projects ever so slightly above the ribs of the groove, and we have found by
experience that the shoe is worn out before the rubber has worn level with the top
of the ribs..
:
If desired the groove may be ribbed or corrugated in which case it will be
preferable to form the rubber with corresponding corrugations or ribs.

Improvements in Horse Shoes.
We, HENRY MARTIN of 25 Almeric Road, Battersea Rise, in the County of
Surrey, Gentleman, and ERNEST HENRY WYLES of 9 Stone Buildings, Lincoln's
Inn, in the County of Middlesex, Solicitor, 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 present invention is an improvement on Henry Martin's Patent No. 17616,
dated 22nd December 1887 which describes a shoe formed with a double groove, in

page_text: one of which is fixed a strip of indiarubber which projects beyond the shoe so that
the tread of the horse is taken on the elastic strip. The strip of indiarubber,.
caoutchouc or other elastic material was placed in a deep groove of circular section,.
and the lower face of the strip was formed of circular. section to fit into the groove
while the upper face was of square section, the strip being secured to the groove by
a suitable cement.
We have found in practice that in hot weather the cement becomes more or less
plastic and the strip of rubber is consequently loosened; to obviate this defect we
have devised means whereby if necessary. the rubber can be fixed in the groove,
without the application of cement, but we reserve to ourselves the right of using a
small quantity of cement if found desirable.
In the Patent above referred to it was stated that the shoes would preferably be
made of wrought iron, but we have found steel more suitable to our purpose, and.
our improvements consist in forming the groove for retaining the rubber strip of
square instead of circular section; and by this arrangement the face of the rubber
strip is reversed; that is to say, the square section of the rubber fits into the square
groove, while the circular section now becomes the face on which the tread of the
horse is taken. The sides forming the groove in which the rubber strip is placed
are turned over the rubber by any suitable tool and thus form a dovetail groove out
of which it will be impossible for the rubber to work loose. If preferred however
we may employ rubber. strips of square or rectangular section.
If desired the groove, may be ribbed or corrugated in which case it will be
preferable to form the rubber with corresponding corrugations or ribs.
The invention will be best understood by reference to the accompanying drawings
in which
Figs. 1 and 2 are respectively a plan and a cross section of a portion of a bar
from which the shoe is made.

Figure 8 is a section of the rubber strip for fitting into said shoe.
Figure 4 is a plan of a horse shoe constructed of the materials illustrated in
Figures 1, 2 and 3, and
Figure 5 is a section of the same on lines 5-5 of Figure 4.
Like letters indicate like parts throughout the drawings.
is
The shoe is constructed of a bar A shown in Figures 1 and 2 and in which
formed the grooves A and B. The grooves A and B are approximately
rectangular and the groove A¹ is adapted to receive a rubber strip C of the section
shown in Figure 3. In course of construction the bar A is bent to the desired
shape and the holes bare punched through the top of the groove B; the nails for
Becuring the shoe to the horse's hoof are driven in through these holes b. The
rubber strip C is held in the groove A by swaging or bending in the walls a as
shown in Figure 5; cement also if desired being used to give additional security.
It will of course be understood that the rubber wears down in course of time but
we have found by experience that the rubber lasts, practically as long as the other
parts of the shoe, and so long as the face of the rubber projects beyond the metal
part of the shoe even though it is only to a very slight extent the horse's tread will
be upon the rubber.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is ;-
1. A horse or similar shoe formed out of a curved metal strip having two
approximately rectangular channels one to receive the pad and the other to
receive the nails substantially as described and illustrated in the accompanying
drawings.
2. In a horse or similar shoe the combination with the metallic portion having
two channels one for the nails and one for the pad of a pad secured in its channel
by swaging or. bending over the walls thereof substantially as described and
illustrated in the accompanying drawings.
