COMPLETE SPECIFICATION.
An Improved Stud, Spike, or Calk for the purpose of Attaching to
the Shoes of Horses or other Animals.
COLLIN CHESTER 17 North Street Edgware Road London N.W. Engineer
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 an improved method of fixing and attaching to the
shoes, of horses or other animals, a stud spike or calk.
For this purpose, I make a stud spike or calk, of steel, iron, or other suitable
material, the head or portion of the said, calk, stud or, spike, that projects beyond
the underside of the shoe (or that part of the shoe that goes next to the ground)
shall be either round, square, oval hexican or any other suitable shape and to be
flat, dimond chisel or hollow pointed. The upper portion of the said calk &c., or
the portion that is intended to go into the shoe of the animal shall be made any
length that is desired, and of any shape, either round, square, oval &c. &c. and to
be made with a slot, cut, or crevice, or any number, of slots, cuts or crevices made
longitudinally tranversley or at any angle and extending from the upper end any
distance down the said calk or stud &c. &c. thus forming a spring in the upper end
of the calk for the purpose of holding the calk in position. The calk or stud &c.
to be made with a shoulder at the division of the upper and lower portions or shall
be made without a shoulder.
In the shoes of the animals that is intended to receive the said calk their shall be
punched drilled or otherwise made holes of any suitable size or shape for the
purpose of receiving the calk or stud in any part of the shoe and in any kind or
shape of shoe.
When the slots, cuts, or crevices, are extended down the upper portion of calk,
stud, or spike, lower than the underside of the shoe, into the lower portion, so that
when the lower portion of the calk, stud, or spike is worn away to the end of the
slots, cuts, or crevices, the upper portion of the calks will become seperated, and
thus loose its holding power wich will cause them to leave the shoe and the holes
theerin free.

Having now particularly described, and ascertained, the nature of my said inven-
tion, and in what manner the same is to be performed, I wish it to be understood
that I do not claim as my invention the making of animals shoe calks or studs or
spikes irrespective of the peculiar and novel manner of fixing the same to the shoe
in such a manner or way as to allow the said calks studs or spikes to be removed or
replaced without taking the shoe from the animals foot. I declare what I claim
First, A calk stud or spike to be attached to the shoes of animals in the manner
herein described, namley by having a slot, cut, or crevice, or any number of slots,
cuts, or crevices, made in the upper portion or shank of the calk and extending
down the calk any distance required.
Secondly, Any shape, calk, stud or, spike of any size, calk, stud, or, spike that is
made with slots cuts or crevices in its upper end of the said calks and extending
down any distance; that will allow the calk to be removed and replaced and when
the lower portion of the calk is worn away to the end of the slots, cuts or, crevices
the upper portions of the calk will become seperated thus lose its holding power
wich will cause them to leave the shoe and the holes theirin free.
Thirdly, The calk stud or spike to be made and constructed and for the purposes
herein specified.
