JOHN PERKS Crown Works Lye near Stourbridge Nail Manufacturer do

I JOHN PERKS, of Lye near Stourbridge in the County of Worcester Nail
Manufacturer, do hereby declare the nature of this invention and in what manner
the same is to he performed, to be particularly described and ascertained in and
by the following statement:-
This invention relates to certain improvements in, or applicable to the construction
of horse shoe cogs for roughing horse shoes in frosty weather, the especial object
being to provide a simple and effectual method of securing the cog to the shoe,
and to render the same more generally servicable, of greater strength, more
durable, and better capable of answering its intended purpose and to attain other
advantages hereinafter pointed out.
As hitherto constructed such cogs with square, or screwed shauks possess certain
disadvantages, as the unscrewing of the screwed cog when in use and consequent
risk of injury to the horses feet, or the decreased strength of the shoe when punched
to receive the square shank.
In accordance with the present improvements, the shanks of my improved self
fitting cogs have six, or more sides round the periphery of the said shanks.
On the accompanying drawing
Fig. 1, represents the end elevation of the hexagon shank A with chisel
point B

By making the shanks with six or more sides (or flats) preferably hexagonal
and octagonal, as in Figs. 3, and 4, a greater area is obtained and consequently
the stability of the cog is enhanced which renders it less liable to fall out of the
shoe than the square shank now generally used.
The square shank is less effectual than the shanks of my invention, as the
former is capable of adjustment only in two positions in the shoe riz. parallel
with the shoe longitudinally, or at right angles with the shoe, whereas the
hexagonal or octagonal shanks can be fixed at any desired angle with the shoe
corresponding with the relative squares in the hole of the shoe, this angularity
of placement is effective in preventing the horses foot slipping in either
direction.

page_text: My improved cogs are forged from steel or other suitable material, in various
sizes from inch upwards.
In order to secure them to the shoe it is necessary only to tap them with a small
hammer.
The set off E, E, Fig. 2, prevents the cog from driving close up to the shoe and
leaves a space between the cog and the surface of the shoe into which the drawing
out tool is inserted and the cog is withdrawn or secured to the shoe in a more
efficient manner than hitherto.
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,
1st. The novelty of the said horse shoe cogs with shanks having six or more
sides (or flats) round the periphery of the said shanks as illustrated in the
accompanying drawing.
2nd. The manufacture and use of the said shanks for all descriptions of horse
shoe cogs as herein before described.
