Improvements in Horse-shoes.
We, OWEN MCQUILLEN, of 201 Dovercourt Road, in the City of Toronto, in
the County of York, and Province of Ontario, Canada, Blacksmith, and WILLIAM
ALEXANDER VERNER, of 16 Spruce Street, in the said City of Toronto, Soda
Water Manufacturer, 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 the invention is to design a horse-shoe in which the calks may be
readily renewed when desired, and it consists essentially of a horse-shoe_blank
having dovetailed recesses formed at the points where the calks are placed, each
calk being made to fit its respective recess and held in position by a removable
block secured by a pin, substantially as hereinafter more particularly explained.
Figure 1 is a perspective bottom view of our improved shoe.
Figure 2 is a cross section through the toe calk.
Figure 3 is a longitudinal section through the toe calk.
Figure 4 is an alternative method of fastening the metal block.
A is the toe calk and B are the side or rear calks.
A dovetailed recess is made in the shoe blank C into which the calk A is fitted.
In order that the said toe calk may be prevented from falling out of its dovetailed
recess, we place behind the calk A, a metal block D, which is dovetailed to fit into
the recess for which it is intended.
A pin E is fitted into a hole made through the shoe blank C behind the metal
block D. This pin may be rivetted at each end so as to prevent it falling out, but
when the calks are made of rubber or similar elastic material, the weight of the
horse standing on the calk causes it to expand so as to press out the metal block D
against the pin E, which pressure we find sufficient to prevent the longitudinal
movement of the pin.
The calks B are slipped into a dove-tailed recess made in each heel, and in front
of each calk B we place a metal block F and hold it in position by a pin G. These
pins may be rivetted, but when the calks B are made of rubber or other elastic
material, their expansion will act in the same manner as the rubber calk A.
When the roads are made of asphalt or similar hard smooth material, the rubber
calks will be found of great advantage as they will enable the horse to travel on
the road without fear of slipping.
We do not confine ourselves to the pin E and block D for securing the calk in
position, as the pin E, by which the calk may be held in the dovetailed recess, will
suffice the purpose.-
In Figure 4, instead of the pin-E-passing sideways through the shoe, we show a
spring pin E passed through the front of the shoe-and through the calk and
passing over the block D¹, so that by springing up the spring pin E¹-the-block
may be removed. There are of course other plans of securing the calk in its
dovetailed recess and therefore we do not, as we have before said, wish to confine
ourselves to the exact means shown.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
1. As a new article of manufacture, a horse-shoe blank having calks fitted into
dove-tailed recesses formed in the said blank, each calk being detachably held in
position by suitable means, substantially as herein shown and described and for the

dove-tailed recesses formed in the said blank, each calk being held in position by a
block fitted into the recess and held by a removable pin, substantially as and for
the purpose specified.
3. The peculiar combination and arrangement of parts, substantially as herein
shown and described and for the purpose stated.
Dated this 1st day of April 1893.
