page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings, in the County of Middlesex 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 consists in an improved method of attaching the caulks to a
horse-shoe, and in the adaptation of the caulks and the horse-shoe for that
purpose.
In the accompanying drawing,
Figure 1 represents a bottom view of a horse-shoe with the caulks attached, the
means of attachment being indicated by dotted lines.
Figure 2 represents a section on the line 1, 1, of figure 1.
Figure 3 represents a section on the line 2, 2 of figure 1.
- Figure 4 is an isometric view showing the side of the toe-caulk next the shoe.
Figure 5 is a similar view of one of the heel-caulks.
Figure 6 is a section on the line 3, 3, of figure 1.
In practice the shoe and caulks are manufactured, and may be sold, separately.
The heel-caulks A are made of the form shown in Figures 5 and 6, their wearing
Burface being of any of the usual forms. On the under side, the heel-caulk is
provided with a projection or lug a. This projection or lug is shown as square but
that form is not essential. The object of this projection or lug is to fit into a
corresponding recess formed in the shoe, and receives substantially all of the strain
which occurs between the caulk and the shoe. In order the better to sustain this
strain the lug is to be preferably inclined towards the heel of the shoe, so that the
strain which occurs in the direction of the arrow, figure 6, will meet with greater
resistance between the lug and the shoe than would be the case if the lug were not
inclined.
.
In order to hold the lug in place within the shoe, and prevent the caulk and shoe
from falling apart, I provide a tapering pin b, which forms a dovetail joint both
with the caulk and with the shoe, as shown in figure 6. The larger end of this
pin, when in position, is flush with the outside surface of the shoe and of the caulk;

page_text: but the smaller end projects sufficiently beyond the inside surface of the shoe and
the caulk to be turned over and rivetted or clinched so as to prevent the pin from
falling out. The caulk, as shown in figure 5, and also the shoe, are, of course
provided with suitable dovetail recesses to receive the pin b.
The toe-caulk is shown at B figure 1, and in figures 2, 3 and 4. The exposed
surfaces of this toe-caulk are of any of the usual forms. cc are two lugs on the
surface of this caulk next the shoe, which lugs are formed like the lug a of the
heel-caulk, but are, preferably, inclined towards the toe of the shoe. The object of
inclining the lugs towards the toe of the shoe is that, in case the horse should
suddenly stub bis toe and thus produce a severe strain in the direction of the arrow
figure 2, the inclination of the lugs will cause them to better sustain the strain
between the caulk and the shoe. Between the two lugs c c is a tapering pin d,
similar to the pin b, and adapted to form a dove-tail joint both with the shoe and
with the caulk B. The large end of this pin, when in position, is about flush with
the shoe and with the caulk on the outer surface; and the smaller end of the pin
extends sufficiently beyond the inner surface of the shoe and the caulk to enable
it to be rivetted or clinched so as to be held in position.
In practice I expect that the shoe and the caulk and the connecting pin will be
manufactured and sold separately and that they will be purchased in lots and
combined by the horse-shoer.
I am aware that attempts have been made to construct a horse shoe in which
the caulks and the main portion of the shoe were separate, and I therefore do not
claim broadly a shoe in which the caulks are separate from the main portion of
the shoe.
The advantages of my improvements over horse-shoes in which the caulks and
the shoe are in one piece are obvious, and the advantages which my invention has
over those shoes in which the caulks and the shoe have been separate arise from
the efficiency of the means of connection which I have provided both as to durability
and facility of attachment and cheapness of manufacture.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign Correspondents, I declare-that what I claim is :-
First. The combination with a horse-shoe of a removable caulk, the said shoe
and the said caulk being secured together by a lug extending from one into the
other, and a pin forming a dove-tail joint with each, substantially as described.
Second. The combination of the horse-shoe with a removable caulk, the said
horse-shoe and the said caulk being connected together by an inclined lug projecting
from one into the other, and a pin forming a dove-tail joint with each, substantially
as described.
Third. A horse-shoe caulk provided with a projecting lug and dovetail recess
whereby it is adapted to be secured to a horse-shoe, substantially as described.
Fourth. A horse-shoe provided at the toe and heel with dove-tail recesses and
holes adapted to receive corresponding projections on the caulks, whereby the
horse-shoe is adapted to be connected with the caulks, substantially as described.
