COMPLETE SPECIFICATION.
An Improved Horse Shoe.
We, JOSEPH HIRSCH, of Kansas City, Missouri, U.S.A., Veterinary Surgeon, and
ALBERT JAMES DAVIES, of Kansas City, Missouri, U.S.A., Clerk Armour Packing
Co., 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:―
The invention relates to an improved horse shoe.
The object of the invention is to provide a shoe with an interchangeable calk,
and with means for securely retaining the calk in position, while at the same time
permitting the calk being removed when worn or damaged, and replaced by a
new one.
With this object in view, the invention consists in certain features of con-
struction and combination of parts which will be hereinafter fully described and
claimed.
In the drawings:-
Figure is a perspective view of our improved horse shoe, showing the calks in
position, the screw studs at the rear of the calk, and the binding lips in the posi-
tion they assume before they are clinched or forced downward over the head of
the screw stud.
Figure 2 is a fragmentary view of the heel of the shoe, showing the position of
the lips after they have been bent down over the head of the screw stud.
Figure 3 is a transverse sectional view through the horse shoe and one of tho
calks.
In the drawings, I represents the horse shoe, which is formed of suitablo
material, preferably high grade wrought iron. The shoe is provided with three
integral sockets 2-3 and 4. formed by the parallel ribs 23 and 4. The toe
socket 2 is arranged transversely across the shoe, while the sockets 3 and 4 are
arranged at the heel of the shoe. These sockets are closed at one end 5 and open
at the other end 6, and are dovetailed in cross section.
7 denotes the detachable calks, the lower edges of which are formed dovetailed,
to correspond with the dovetailed sockets with which they are engaged.
S denotes screw studs that engage screw threaded apertures at the entrance to the
sockets, and act as stops to prevent the calks sliding from engagement with said
sockets.
By referring to Figs. 1 and 2, it will be noticed that the ribs forming the
sockets are of greater length than the calks, and partially surround the heads of
the screw studs. For convenience of reference, we will term these portions that
surround the heads of the screw studs "lips
" and b."
After the calks have been inserted, as shown in Fig. 1, and the screws worked
into their respective apertures, to prevent the disengagement of the calks from
their sockets, we compress the lips and b partially over the heads of the screw
studs. so as to prevent said studs working loose.

When it is desired to remove the worn calks, for the purpose of replacing them

page_text: with new ones, these lips may be spread apart by any suitable tool, the screw
studs removed, and the calks taken out and new ones substituted.
The screw
studs are then engaged with the shoe, and the lips compressed over their heads
to prevent them unscrewing. By using good material for the shoe, we are enabled
to repeat this operation of bending the lips several times, or we might say, until
the shoe has worn out.
While we have shown and described screw studs for holding the calks in post-
tion, and while we prefer to employ screw studs for this purpose, we would have
it distinctly understood that we reserve to ourselves the right to use any form
of stud or locking means that will perform the same function, and be retained
by the compression of the lips.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that whai
we claim is:-
1. A horse shoe formed with dovetailed sockets open at one end and closed at
the other, the ribs forming said sockets being provided with compressible lips at
the open end of said sockets, calks having dovetailed portions to engage said
sockets, and studs arranged at the open end of said sockets between the lips,
whereby when the lips are compressed the removal of the studs is prevented, sub-
stantially as and for the purpose set forth.
2. A horse shoe formed with dovetailed sockets open at one end and closed at the
other, the ribs forming said sockets being provided with compressible lips at the
open end of said sockets, calks having dovetailed portions to engage said sockets,
and screw threaded studs arranged at the open end of said sockets between the
lips, whereby when the lips are compressed the removal of the studs is prevented,
substantially as and for the purpose set forth.
