page_text: I, FREDERICK AUGUSTUS ROE, of the City and State of New York, United States
of America, at present residing at 10 Duchess Street, Regent Street, in the County
of Middlesex, Gentleman, do hereby declare the nature of this invention to be as
follows:-
My invention relates to horse-shoes of the kind or class described in the
specifications of former Letters Patent dated 30th October, A.D, 1879, N° 4424,
and 5th July A.D, 1882 N° 3177.
These horse-shoes are divided for a portion of their length on each side so as to
form springs or elastic portions which will yield under the horse's weight and thus
prevent or avoid injury by concussion when the horse is travelling upon a hard
road or pavement.
I have ascertained that such shoes, as heretofore made, do not
possess sufficient elasticity to enable the horse's weight to compress the springs, and
bring their ends in contact with the body or main portion of the shoe. The chief
object of my present invention therefore is to increase the elasticity of such shoes.
In the manufacture of these spring horse-shoes, as heretofore practised, the inner
or outer part of each side of the shoe is pressed downward and sheared by a pair
of dies the object being to form the springs or elastic portions. These portions are,
however, of such thickness that they are too stiff or rigid and will not yield
properly under the horse's weight. In making horse-shoes according to my present
invention, I make the springs or elastic portions in such a manner that they
gradually decrease in thickness from the heels of the shoe to, or nearly to, the toe
thereof. The said springs therefore at those points where they are required to
yield or bend, are thin as compared with the body or main portion of the shoe and
consequently have considerable elasticity.
I prefer to make the upper surface of the inner part of the shoe at the toe slightly
concave in order to avoid any contact of the soft part or sole of the horse's foot
with the shoe. These results I usually accomplish by the use of rolls or drop-dies
or both rolls and drop-dies of such shape or configuration that they will impart the
desired shape to the shoes.
By making horse-shoes in this manner I provide for greatly facilitating the
travelling of horses over hard roads or pavements, as the said shoes have much
more elasticity than those wherein the springs are made throughout of the same
thickness as the body or main portion of the shoe.

page_text: I sometimes make the shoe rounded or bevelled at its outer edge on the under-
side instead of forming it with a sharp corner in the ordinary manner. I thus
provide for facilitating the rolling motion of the horse's foot in lifting his heel from
a road or other surface, and for enabling the horse to get over easily on his toes,
thereby relieving the back tendons from the strain that is put upon them when the
shoes are made with sharp corners. Shoes made with rounded corners in the
manner above described are very advantageous for sore or lame horses.
My spring shoes are sometimes formed by bending and otherwise shaping two
plates or pieces of metal and uniting the same at the toe of the shoe by welding.
In shoes of this kind I prefer to bevel the said two plates or pieces so that, when
the shoe is completed, the relative positions of these bevelled parts will be such
that the shoe will not be liable to be clogged by mud or other substance entering
and accumulating between the springs and the body or main portion of the shoe.
Or I form the said plates or pieces in any other suitable manner for this purpose.

page_text: I, FREDERICK AUGUSTUS ROE, of the City and State of New York, United States
of America, at present residing at 10 Duchess Street, Regent Street, in the County
of Middlesex, Gentleman, do hereby declare the nature of my invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
My invention relates to horse-shoes of the kind or class described in the
Specifications of former Letters Patent dated 30th October A.D. 1879, No 4424,
and 5th July A.D. 1882, N° 3177, that is to say, horse-shoes which are cut or divided
vertically for a portion of their length on each side in such a manner as to form
springs or elastic portions that will yield under the horse's weight and thus
avoid injury by concussion when the horse is travelling upon a hard road or
pavement.
I have ascertained that the springs of such shoes, as heretofore made, do not
possess sufficient elasticity to permit their compression by the horse's weight to an
adequate extent to ensure contact between their rear ends and the body or main
portion of the shoe. The chief object of my present invention, therefore, is to
increase the elasticity of these springs.
My said invention, moreover, comprises various improvements herein-after
set forth.
In the accompanying drawing.

Specifications.

invention.
Like letters indicate corresponding parts throughout the drawing.
In the manufacture of the said spring horse-shoe, as heretofore practised, each
side of the shoe is sheared from near the heel to within a short distance from the
toe, as shown in Figures 1 and 2, and the inner parts a of the shoe are bent
downward by means of a pair of dies, the object being to make the parts a serve
as springs or elastic portions. These portions, however, are of the same thickness
throughout as the body or main portion of the shoe, and are, therefore, too stiff or
rigid to yield properly under the horse's weight.
In making horse-shoes according to my present invention, I make the springs or
elastic portions in such a manner that they gradually decrease in thickness from
the heels of the shoe to near the toe thereof, as shown in Figure 4, the thinnest
parts being preferably at a¹, that is to say, at the points where they are required
to yield or bend. The said springs, therefore, at these points, are thin as compared
with the body or main portion of the shoe and consequently have considerable
elasticity.

page_text: I prefer to make the upper surface of the inner part of the shoe at the toe slightly
concave, as shown at a' in Figure 4, in order to avoid any contact of the soft part
or sole of the horse's foot with the shoe.
I usually reduce the thickness of the springs or elastic portions, in the manu-
facture of the shoe, by means of rolls or drop-dies or both rolls and drop-dies of
such shape that they will impart the desired configuration to the shoe.
By making horse-shoes in this manner, I provide for greatly facilitating the
travelling of horses over hard roads or pavements, as the said shoes have much
more elasticity than those wherein the springs and the body or main portion of the
shoe are of the same thickness throughout as shown in Figure 2.
The shoe shown in Figure 5 is rounded or bevelled at its lower front edge b,
instead of being formed with a sharp corner in the ordinary manner. By this
improved formation of the shoe, I provide for facilitating the rolling motion of the
horse's foot in lifting his heel from a road or other surface, and for enabling the
horse to get over easily on his toes and thereby relieving the back tendons from
the strain that is put upon them with shoes having the ordinary sharp corners.
Shoes which are rounded or bevelled in the manner above described are very
advantageous for sore or lame horses. This part of my invention is applicable
to horse-shoes made without springs or clastic portions, as well as to spring
horse-shoes.
I sometimes make my spring shoes by bending and otherwise shaping two
plates or bars of metal a, a Figures 6, 7 and 8, and uniting the same at the toe
by welding. In shoes of this kind, I bevel the said plates or bars as at a, a, so
that, when the shoe is completed, the bevelled parts will occupy such relative
positions that the shoe will not be liable to be clogged by mud or other substance
entering and accumulating between the springs and the body or main portion of
the shoe. Or I bevel the said plates or bars in any other suitable manner for this
purpose.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I wish it understood
that I claim :-
First A spring horse-shoe wherein the springs or clastic portions are reduced
in thickness, substantially as, and for the purpose, set forth.
Second A horse-shoe which is made with its lower front edge rounded or
bevelled, as, and for the purpose, set forth.
Third A spring horse-shoe consisting of two plates or bars bent to the required
shape and bevelled for the purpose specified, and united by welding as above
set forth.
Fourth The .improved horse-shoe made substantially as shown in Figures 3
and 4, or in Figure 5, or in Figures 6, 7 and 8 of the drawing for the purposes
specified.
