Improvements relating to Horse-shoes.
I, ALLEN HENRY ROWE, of 5, Rowe Avenue, Hartford, Conn., U.S.A., Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to produce a horse-shoe having calks which will
prevent slipping, which will not work loose, which can be readily removed when
worn, and be replaced by new ones, and which will be found to be self-sharpening.
The invention comprises a horse-shoe having screw-threaded apertures through
it, at intervals. Calks are fitted into these apertures, and consist of screw-threaded
studs having square heads adapted to be manipulated with a wrench so as to
adjust the screw-threaded portion into the apertures in the shoe with the under
face of the head impinging tightly against the under face of the shoe. The face
of the nut is roughened with inclined chisel cuts forming teeth which tend to
bite into the under face of the horseshoe and prevent the calk from working loose.
The upper surface of the head of the calk has a conical-shaped projection upon
it.
It will be found that calks of the shape described will wear pointed as it wears
shorter owing to the friction of gravel etc. on its circumference. The calk may
be made entirely of steel or it may be made with a steel centre portion.

Improvements relating to Horse-shoes.
I, ALLEN HENRY ROWE, of 5, Rowe Avenue, Hartford, Conn., U.S.A., Manu-
facturer, 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 object of this invention is to produce a horse-shoe having calks which will
prevent slipping, which will not work loose, which can be readily removed when.
worn and be replaced by new ones, and which will be found to be self sharpening.
In the drawings hereunto attached, Figure 1 is a plan of the underside of a
horseshoe comprising my invention. Fig. 2 is a side view of a calk. Fig. 3 is
a view of the underside of a calk.
The invention comprises a horseshoe A. The calks B consist of screw-threaded
studs C having square or angular heads D adapted to be manipulated with a

page_text: wrench to adjust the screw-threaded portion into the screw-threaded apertures
in the shoe, with the under face E of the head impinging tightly against the
under face of the shoe. The under face of the head is roughened with inclined
chisel-cuts forming teeth F which tend to bite into the under face of the horse-
shoe and prevent the calks from working loose.
The upper surface of the head of the calk has a conical-shaped projection G
upon it. If preferred, the conical-shaped projection may be squared to form the
head as shewn at H.
It will be found that a calk of the shape described will wear pointed as they
wear shorter, in consequence of the friction of gravel etc. on its circumference.
The calk may be made entirely of steel or it may have its centre made of steel
and its outer part of softer metal, such as iron.
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;
-
(1) In a horseshoe provided with calks upon its underside, said calks consisting
of a screw-threaded stud adapted for engagement with screw-threaded apertures
in the shoe, a square or angular head on said stud, and a conical-shaped projec-
tion upon said head, substantially as and for the purposes herein before set forth
and illustrated in the drawings hereunto annexed.
(2) In a horseshoe provided with calks, said calk consisting of a screw-threaded
stud adapted for insertion in screw-threaded apertures in the shoe, a head on the
stud having its underside roughened or formed with teeth, and a conical shaped
projection on the upper surface of the head, substantially as and for the purposes
herein before set forth and illustrated in the drawings hereunto annexed.
(3) In a horseshoe provided with calks upon its underside, said calks consisting
of a screw-threaded stud adapted for engagement with screw-threaded apertures
in the shoe, a square or angular head on said stud, and a conical shaped projec-
tion upon said head, having its interior portion made of hard steel and its outer
portion of softer metal, substantially as and for the purposes herein before set
forth and illustrated in the drawings hereunto annexed.
Dated this 9th day of November 1898.
