COMPLETE SPECIFICATION.
Improvements in Horse Shoes.
I, ELI BOUCHARD, a citizen of the United States of America, residing at
No. 2 Armory Court, in the City of Worcester, in the County of Worcester and
State of Massachusetts, Manufacturer, 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:-—
My invention relates to horse shoes, and to that class of horse shoes which are
provided with removable toe, and heel calks, and the object of my invention is to
improve upon the construction of said horse shoes, as now ordinarily made, and to
make a horse shoe having removable toe, and heel calks, which calks can be quickly
and easily attached to, and detached from the shoe proper, without removing
the shoe, and be rigidly secured thereto without any liability of becoming
accidentally detached therefrom.
My invention consists in certain novel features of construction of a horse shoe
provided with removable toe, and heel calks, and of the calks, as will be hereinafter
fully described.
Referring to the drawings:-
1
Fig. 1 is a view of the bottom of a horse shoe, embodying my improvements, with
the removable toe, and heel calks in place.
Fig. 2 is a cross section, taken on line 2, 2, Fig. 1, looking in the direction of
arrow a, same fig.
Fig. 3 is a cross section of the toe calks removed, taken on line 3, 3, Fig. 1,
looking in the direction of arrow b, same fig.
Fig. 4 is a side view of the right hand heel calk, removed, looking in the direction
of arrow c, Fig. 1.
Fig. 5 is a plan view of the left hand heel portion of the shoe, with the calk
removed, and,
Fig. 6 is a longitudinal section, on line 6, 6, Fig. 5, looking in the direction of
arrow d, same fig.
In the accompanying drawing, 1 is the shoe, which may be of any ordinary shape,
and provided with nail holes 2, and grooves 3 for the nail heads, in the ordinary
way, 4 is the toe calk, and 5 the heel calks.
The shoe 1 is provided with a depression or recess 6, in the underside thereof, at
the toe and heel portions, where the calks are attached to the shoe..
The recess 6, at the toe portion, and also at the heel portion of the shoe, is
preferably of a depth equal to one-third or more of the thickness of the shoe, and
of the same width as the width of the shoe, and of a length corresponding to the
length of the base of the calks, which are fitted in said recess, so that the ends of
the base of the calks will bear against the ends of the recess, as shown in the case
of the toe calk, in Fig. 2.
The recess 6 is provided with a boss or thimble 7, extending up therefrom, said
thimble 7 has a screw threaded hole 8 extending through it, and also through the
shoe, see Figs. 2 and 6, and the length of the thimble 7 is a little less than the
thickness of the base of the calk.
In the recessed portion 6 of the shoe is a hole 9, extending through the shoe.
In the heel portion of the shoe there is preferably one hole 9, see Figs. 5 and 6;
and in the toe portion, two holes 9, as indicated by dotted lines Fig. 1.
The toe calk 4; and the heel calks 5 are provided with the base portions 4',
and 51, adapted to fit into the recesses 6, said base portions have a hole 10 therein,
to receive the thimble 7, and a stud 11 on the underside thereof, to extend into the
holes 9 in the shoe.

page_text: In the case of the toe calk 4, there are preferably two studs 11, as shown in
Fig. 2, while in the heel calks 5, there is preferably only one stud, 11, as shown in
Fig. 4.
The toe calk 4, and heel calks 5 are secured in the recesses 4, and to the shoe,
by screws or bolts 12, which are screwed into the threaded hole 8, in the thimble 7
and in the shoe, and have their heads bearing on the outer surface of the base of
the calks, as shown in Fig. 2.
The outer surface of the base portion of the calks is preferably provided with
ridges or extensions. In the case of the toe calk 4 there are two ridges or
extensions 13, one on each side of the bolt head 12, extending at right angles to the
calk to enclose the bolt head, and in the case of the heel calks 5, there is one ridge
or extension 14, on the inner end of the base portion 5', opposite from the calk
end, which ridge 14 is preferably made angular as shown in Fig. 1, and partially
encloses the head of the bolt 12.
The ridges or extensions on the outer surface of the base portions of the calks,
extend slightly beyond the outer surface of the bolt head 12, when the calks are
secured to the shoe, as shown in Fig. 2.
The object of the ridges 13 and 14 is, in connection with the calk, to form an
enclosed space substantially enclosing the bolt head, which space will become filled
up with dirt, etc., as the shoe is used. The dirt, etc., will serve to hold the bolt
head, and prevent it from turning, and getting loose; and the ridges or extensions
will also protect the bolt head, and prevent it from coming in contact with the
ground, and from striking on stones or hard substances, which might turn it, and
loosen it.
The advantages of my improved horse shoe, will be readily appreciated by those
skilled in the art.
It is only necessary to remove the screw bolt 12,-to, take off the calks, and new
calks are secured by simply screwing in the bolt 12 without removing the shoe.
In the winter time, when there is ice, long sharp calks may be used, and in summer,
and on pavements, short, or smooth calks may be used, as desired.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination with a horse shoe, of calks fitting in recesses in the shoe, and
provided with one or more studs fitting in, holes in the shoe, and an opening fitting
over a boss or thimble on the shoe, and a ridge, or ridges extending out from the
base of the calk to protect the head of the bolt or screw which secures the calk to
the shoe, and said bolt or screw, adapted to engage a threaded hole in the shoe,
substantially as set forth.
2. The combination with a horse shoe, having a recess in its toe, and heel
portions, and a hole, or holes in said recess, and a boss or thimble extending up
from said recess provided with a threaded hole, said hole extending through said
thimble and shoe, of a calk adapted to fit into the recess, and having one or more
studs extending into the holes in the recess, and provided with a ridge or ridges on
its base to protect the head of the bolt or screw which secures the calk to the shoe,
and said bolt or screw, substantially as set forth.
3. A horse shoe having removable calks fitting in recesses in the shoe, and
provided with one or more studs fitting in holes in the shoe, and an opening fitting
over a boss or thimble on the shoe, and a bolt or screw holding the calks in place
on the shoe, substantially as described.
