PROVISIONAL SPECIFICATION.
Improvements in or appertaining to Frost Cogs for Horseshoes.
I, ARTHUR HARRISON, of 40, James Street, Bradford, in the County of York,
Blacksmith, do hereby declare the nature of this invention to be as follows:-
:―
This invention relates to improvements in that type of frost cog for horseshoes
in which the cog is provided with a tenon or projection fitting a mortise or hole in
the shoe, and the said improvements consist in forming the said tenon of "three-
square or triangular cross section and in making the said mortise of corresponding
form.
"
By this construction in case the cog wears or becomes loose it may be wedged
tightly in its mortise on all sides by inserting one piece of thin sheet metal or other
suitable packing against one of the sides of the tenon. Hitherto with the usual
rectangular form of tenon when the cog is loose it is generally necessary to insert
two pieces of packing, which besides being more awkward to deal with are difficult
to fit.
In case a front or " toe cog is fitted to the shoe it may have one triangular
tenon and two or more pins or equivalent projections as well.

Improvements in or appertaining to Frost Cogs for Horseshoes.
I, ARTHUR HARRISON, of 40, James Street, Bradford, in the County of York,
Blacksmith, 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 :-
This invention relates to improvements in that type of frost cog for horseshoes
in which the cog is provided with a tenon or projection fitting a mortise or hole in
the shoe, and the said improvements consist in forming the said tenon of "three-
square or triangular cross section and in making the said mortise of corresponding
form.
"
By this construction in case the cog wears or becomes loose it may be wedged
tightly in its mortise on all sides by inserting one piece of thin sheet metal or other
suitable picking against one of the sides of the tenon. Hitherto with the usual
rectangula form of tenon when the cog is loose it is generally necessary to insert
two pieces f packing, which besides being more awkward to deal with are difficult
to fit.
Reference is to be had to the accompanying sheet of drawings forming a part
of this Specification, in which similar letters of reference indicate corresponding
parts in each of the figures.
Figure 1, represents a plan view of the upper side of a horseshoe.
Figure 2, represents a view of the underside of the same.

page_text: Figure 4, represents a section on the broken line a, b Figure 1.
Figure 5, represents a section on the line y, z Figure 1.
Figures 6 and 7 respectively represent a front elevation and a plan view of a toe
cog. And Figures 8 and 9 are similar views of one of the rear or "heel" cogs.
The shoe A has a triangular hole B. formed in each extremity and a similar
hole B 2 formed at the front in the middle of the shoe. The heel cogs C, C have
each a triangular tenon C 2 formed on them which tenon is tightly driven into the
mortise to secure the cog in position.
The toe cog C3 is also provided with a triangular tenon C 2 which is driven
tightly into the hole B 2 and as this cog is comparatively broad the round pins or
studs D are formed on the cog to fit the holes E in the shoe and thus strengthen
the attachment of the cog to the shoe. Instead of one toe cog two or more narrow
cogs may be placed side by side each secured by a triangular tenon fitting &
triangular hole in the shoe.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1. The combination with a horseshoe having a triangular hole, of a cog provided
with a triangular tenon adapted to be secured in said hole, substantially as herein
shown and described.
"
2. A "toe cog for horseshoes having a triangular tenon to fit a triangular hole
in the shoe and one or more pins adapted to fit holes in the shoe, substantially as
herein shown and described.
