I, ANDREAS WÜLKER, of 22 a Müllerstrasse, Berlin, Germany, Merchant, 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 follow-
ing statement;-
--
The present invention has reference to improvements in horse shoes and more
especially to horse shoes with projecting portions, known as heel and toe calks,
and the object of the invention is to provide a horse shoe, the calks of which
are readily exchangeable. As the calks are the parts of a horse shoe most sub-
jected to wear, they require frequent sharpening and replacement by new ones.
The shoes now in use, with the calks screwed in, are objectionable inasmuch
as the shoe has to be taken off the animals foot each time one of these screw
calks has broken off. The threaded end of the calk has then to be bored out of
the shoe, before a new one can be inserted. This process is expensive and
requires considerable time.
According to my invention I provide a horse shoe which permits of the broken
off or blunt calk being removed and a new one being set in, without necessi-
tating a removal of the shoes from the foot of the animal. The entire operation
only requires a few minutes without the least annoyance to the animal.
In order to make my invention more readily understood, I have illustrated it
on the accompanying sheet of drawings, Fig. 1 of which shows a plan view of a
horse shoe, according to my invention. Fig. 2 is a sectional elevation on line X--X
of Fig. 1, with part of the horse shoe broken away.
In the horse shoe 1 at the thickened portions, where the toe and heel calks are
to be arranged, I provide recesses 2 wider at the bottom than at the entrance.
The calks taper towards one end and are provided at the taper end with a flange
or base plate 4, as is clearly shown in Fig. 2. A groove 5 is arranged on one
side of the calk and extends from the flange or base plate 4 to or nearly to the
tread face of the calk. I may also see fit, to use two grooves 5, opposite each
other. The calks may have any desirable tread face; it may be flat, pointed,
grooved, H-shaped or of any other shape desired.
For securing the calks in the corresponding recesses, I insert them in the
manner shown in Fig. 2 and grip the horse shoe about the recessed portion with
a pair of hot tongs or apply a heated iron to it; I then apply a bismuth alloy,
for inst. the well known Wood's alloy, to the heated calk, when the alloy will
readily melt and run through the groove or grooves 5 into the recess 2. After
removal of the hot tongs or other tool, the alloy soon hardens and secures the calk
in the recess.
If a replacing of a broken or blunted calk by a new one is called for, the
shoe is heated, while on the animals foot, when the calk can readily be removed
and a new one set in. The whole operation only takes a few minutes and causes
to the hamsa

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
In a horse shoe the combination of recesses in the thickened toe and heel
portions, tapering towards the opening, and calks, tapering towards one end and
having a flange or base plate at the taper end and a groove or grooves, extending
from the said base plate to or nearly to the tread face of the calk, said calks being
adapted to be inserted, with the flanged end foremost, into the said recesses, and
means to secure the said calks in the said recesses, substantially as shown and
described.
