An Improvement in Horse-shoes.

page_text: An Improvement in Horse-shoes.
We Comte MAURICE D'AMILLY of 63 Avenue de l'Alma and JUSTIN CAILLET
of 146 Rue Cardinet both in Paris, France 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 an improved horse shoe which is elastic in the lateral
direction so as to readily adapt itself to and avoid cramping the hoof, is very light,
and is sufficiently resilient in itself to lessen the shocks to the foot.
The improved horse shoe which thus fulfils all the conditions essential to a healthy
condition of the animals foot consists essentially of a steel band set edgewise and
forming inner and outer walls, the intervening space being filled by a packing formed
of a core of hard twisted rope or other material fixed therein by any suitable means
and covered on the wearing surface with agglomerated. and..compressed emery or
other equivalent material.
In order that the invention may be more readily understood I have illustrated it in
the accompanying drawings forming part of this Specification wherein
Figure 1 is a top plan of the improved shoe,
Figure 2 is a rear view partly in section on line 1-2 Figure 1.
The same letters of reference indicate the same parts in both figures.
a is a core formed of a hard twisted hemp rope which may be coated or
impregnated with a suitable antiseptic substance. Twisted or plaited hemp has
been found to give the best results, as in use, and especially when covered as hereafter
described, it becomes macadamised so to speak and constitutes a compact mass having
great cohesion, but we do not restrict ourselves to the use of such cord.
This core is held between the inner and outer members of an endless strip b of steel
bent to the form of a horse shoe as shown, the said inner and outer members being
held at the requisite distance apart to form the inner and outer walls of the shoe by
cross rivets c which transfix the rope a and so hold it in place. The said strip of
steel is cut out with the toe clip d in one with it and being placed edgewise, as shown,
the lateral elasticity of the shoe will be readily understood. Upon the under side of
the rope core is applied a filling of a rough character whereby slipping is entirely
prevented. This consists of a basis of coarse emery fixed by glue or other
suitable agglutinant and filling up the interstices between the rope core and the
surrounding steel band, the agglomerated mass being pressed into the said interstices
by any suitable means and partially filling up the space between the inner and outer
walls. A second layer of finer emery is then applied and compressed, this facing
layer standing out beyond the metal so as alone to come into contact with the
ground. The agglomerated emery becomes incorporated with the rope and the whole
constitutes a compound shoe which although its wearing surface is wholly composed
of emery possesses all the necessary elasticity.
Although emery has been specified as being the best for the purpose, other
materials may be used for producing the same results.
The horse shoe thus made is affixed by nailing directly through the rope, the
direction of the nails through the wall of the hoof being determined at will without
regard to the fullering necessarily formed in iron shoes whether of flat, angle, or
channelled, section. The wall of the hoof rests directly upon the rope filling which
forms an elastic cushion to deaden the shock of striking hard ground and the elastic
shoe readily adapts itself to hoofs of different form. This improved shoe replaces
with advantage the ordinary iron shoe, of whatever form of bar it may be made,
which has no lateral elasticity whereas the improved shoe being formed of a steel
strip placed edgewise is very elastic, requires much less metal, and is very light,

page_text: 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. An elastic horse-shoe composed of a core of flexible material surrounded by
a metal band placed edgewise so as to have lateral elasticity, substantially as
specified.
2. A horse-shoe composed of an endless strip of steel bent to form the inner
and outer walls of the shoe, the strip being placed edgewise and of a rope core
secured between the inner and outer walls and covered on the underside with a
facing of emery to form the wearing surface the upper side of the rope forming
a soft bed for the hoof, substantially as specified.
