Office," Southampton Buildings, London, Doctor of Laws, for the
Invention of "IMPROVEMENTS IN HORSE-SHOES." -A communication

COMPLETE SPECIFICATION filed by the said George Haseltine at the
Office of the Commissioners of Patents, with his Petition and
Declaration, on the 15th July 1874, pursuant to the 9th Section
of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," Southampton Build-
ings, London, Doctor of Laws, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS
IN HORSE-SHOES," and have petitioned Her Majesty to grant unto me,
my executors, administrators, and assigns, Her Royal Letters Patent for
the same, and have made solemn Declaration that it has been com

NOW KNOW YE, that I, the said George Haseltine, do hereby declare
that the following Complete Specification, under my hand and seal,
fully describes and ascertains the nature of the said Invention, and in
what manner the same is to be performed, in and by the following
statement, reference being had to the accompanying Drawing forming
a part of this Specification:-
Figure 18 a bottom view of the said horse-shoe; Figure 2 a side
elevation of the same; Figure 3 is a section at ; and Figure 4, à
section at y, Figure 2; Figure 5 is a horizontal section of part of the
shoe at 2, Figure 3.
In Figure 1 I have represented the under side of my improved shoe.
a, a, represent a series of side calks, each of which is convex on the
outside and concave on the inside. Between these side calks are deep
recesses b. The calks being convex upon the outside a space i, see
Figures 1 and 4, is left between the several calks to receive the nails.
7 may be considered as a plate to which the calks are attached, although
in manufacturing the part and calks may be all made together. e is
the toe calk of ordinary construction. It is not necessary to have a
recess 6 between the last side calk and the heel calk, but I prefer this
construction. The heel calk d is grooved out or cut away on the top
furnishing two. bearings for each calk.
It will be observed that what might be considered as the base of the
calk is very broad and strong, the calk on the inside running down on
an incline to the inner edge of the plate h. The outside of the calk is
slightly inclined as well as curved to allow the shoe to be easily drawn
from the earth. By this mode of construction I provide the shoe with a
number of side calks upon each side, each independent of the other, and
yet sufficiently connected to be strong, furnishing a number of points to
prevent slipping. The form of these calks upon the inside is such that

page_text: the shoe will be self-cleaning: This shoe is suitable for summer or
winter use.
The most convenient way of manufacturing the said shoe so that it
will be durable is to cast it from steel, but I do not wish to limit myself
to this specific mode of manufacturing.
This improved shoe furnishes a support for the foot of a horse at all
points as perfectly as does a shoe having a continuous calk without the
objections to such calk. At the same time the construction of the side
calks is such that in whatever position the foot comes in contact with
the ground it will be almost impossible for the horse to slip. The
convex form upon the outside of the calk is the most perfect that can
be devised for the purpose, and at the same time it enables me to provide
the recesses i to receive the nails.
Having thus fully described the said Invention as communicated to
me by my foreign correspondents, and the manner of performing the
same, I wish it understood I am aware that shoes have been made
having side calks, and do not therefore claim broadly such a shoe, but
I claim,―
First. A horse-shoc with a series of side calks a, convex on the out-
side, with spaces i for the nails, and with recesses 6 between the several
calks, as herein set forth and for the purposes specified.
Second. The heel calk & cut away to form two bearing surfaces for
the same, as herein set forth.
In witness whereof, I, the said George Haseltine, have hereunto set
my hand and seal, this Fifteenth day of July, in the year of our
Lord One thousand eight hundred and seventy-four..
