Improvements in Horse Shoes.
I, JACOB BENNETT WALLACE, of the City of Erie, County of Erie, and State of
Pennsylvania, United States of America, Mechanical Engineer, 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:-
This invention relates to horse shoes, and consists in certain improvements in
the construction thereof, as will be hereafter fully described and pointed out in
the claims.
Heretofore horse shoes have been sold to horse shoers in the form of flat metal
plates, and the shoer has formed calks on these plates by turning down the ends
for the rear calks, and by welding on the front calk. This construction has
certain limitations, among which may be stated the difficulty in using for the
calks, a different metal from that of the plates; restrictions as the metals possible
or practical to use for calks; the difficulty in replacing the calks; and restrictions
as to the location of the calks on the shoe.
I propose to remedy this and as additional feature to form the calks of some
metal preferably different from that of the plates, the temper or wearing quality
of which is not interfered with by the heat incident to brazing.
The invention is illustrated in the accompanying drawings as follows:
Fig. 1 shows an end elevation of the shoe.
Fig. 2 shows a plan view.
Fig. 3 shows a side elevation.
Figs. 4, 5 and 6 show the calks detached.
A marks the hoof plate; B the front calk; and C the rear calk.
I prefer using what is known as self hardening steel, as the material for the
calks, as it is not readily abraded, and from its inherent quality, remains hard
after the heating due to brazing. Other material not affected as to quality by
the heat of brazing may be used.
The calks may be placed in any position on the shoe; thus the plate may be
extended back to the rear calk, to support the heel of the horse, and the point of the
calk may be placed away from the edge of the plate; if desired to change
the calks or renew them, it is only necessary to heat the shoe sufficiently to melt
the brazing material. The calks will then drop off, or can be easily removed.
This feature is particularly desirable when the horse is used on icy pavements as
the non-abrading quality of the harder metal, thus made practical, wears longer,
and when the calks become smooth they can be readily replaced.
The plates may be of some easily worked material. As the range of metals
which can be joined by brazing is much greater than those which can be united
by welding, so that the most desirable material for both the plates and calks can
be used. Numerous attempts, involving the expenditure of large sums of money,
have been made to effect this result as by casting; by making special drop forgings;
using peculiar methods of tempering, etc. but so far as I am able to ascertain
nothing has been devised which is so effectual as my device.

page_text: Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
1. As an article of manufacture, a horse shoe comprising a metal hoof plate
and a calk or calks secured to said plate by brazing.
2. As an article of manufacture, a horse shoe comprising a metal hoof plate
and a calk or calks, secured to said plate by brazing; said calk or calks being
formed of material the non-abrading quality of which does not deteriorate by
reason of the heating incident to brazing.
3. As an article of manufacture, a horse shoe comprising a metal hoof plate and
a calk or calks, secured to said plate by brazing; said calk or calks being formed
of material differing in quality or character from the material of the plate, and
being of such quality or character as not to be injured relatively to its use as a
calk by the heat incident to brazing.
4. As an article of manufacture, a horse shoe comprising a metal hoof plate,
and a calk or calks, secured to said plate by brazing, said calk or calks being formed
of a material differing in quality or character from the material of the plate, the
non-abrading quality of which material forming the calk or calks, does not
deteriorate by reason of the heating incident to brazing.
