I HENRY THOMAS PEARCE of London Road, Stroud in the County of Gloucester
Shoeing smith, &c. do hereby declare the nature of this invention to be as follows:-
This invention relates to the manufacture of Frost screws or cogs, designed to afford
animals increased foothold in frosty or slippery weather.
A frost screw or cog constructed according to this invention is formed of iron,
stoel or other suitable metal, which may be either screwed or driven into the shoe, as
the case may be the part that projects below the under surface of shoe, to he made
with an indent or hole in same, so as to form cutting edges or ring on the outside of
the Frost screw or cog, and the indent or hole in the frost scrow or cog to be filled
with indiarubber or other suitable material to prevent snow or dirt from entering, and
also to prevent the animal from slipping. The sides of the frost screw or cog to be
parallel with each other, so that they will retain their efficiency until worn down level
with the shoe, and may be easily put into or taken out of the shoe with a spanner or
wrench without fear of the spanner or wrench slipping off, as is the case with chisol
shape or pointed cogs or frost screws.
Frost screws or cogs made in this manner are not so dangerous to horses or animals
cutting their legs, as is the case with the chisel shape or pointed cogs or frost screws.

I HENRY THOMAS PEAROE, of London Road, Stroud, in the County of Gloucester,
shoeing smith, 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 the manufacture of Frost screws or cogs, designed to
afford animals, increased foothold in frosty or slippery weather.
A Frost screw or cog, constructed according to this Invention, is formed of iron
or steel or other suitable metal, which may be either screwed or driven into the shoe
as the case may be; the part that projects below the under surface of the shoe, to be
made with an indented surface or hole in the same, so as to form cutting edges or ring
on the outside of the frost screw or cog, an the indent or hole in the frost screw or
cog to be filled with Indiarubber or other suitable material, to prevent snow or dirt
from entering, and also to prevent the animal from slipping. The sides of the frost
screws or cogs, to be parallel with each other, so that they will retain their efficiency
until worn down level with the shoe, and may be easily put into or taken out of the
shoe with a spanner or wrench without fear of the spanner or wrench slipping off as
is the case with chisel-shaped or pointed cogs or frost screws.

page_text: Fig. 2. shews one of the frost screws or cogs, made to drive into-shoe, shouldered,
and shank slightly tapered.
Fig. 3. shews frost screw or cog, as toe piece for front of shoe, made to drive.
Fig. 4. is a section of No. 2. through centre shewing the indent or hole.
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. A Frost screw or cog, formed with an indented surface, so as to form. cutting
edges or ring.
2. The indent or ring to be filled with Indiarubber or other suitable material.
3. That frost screws or cogs, made in this manner are not so dangerous to horses,
or animals-cutting their legs, as is the case with the chisel shaped or pointed cogs or
Frost screws.
