PROVISIONAL DI FULTIVATION.
Improvements in and connected with Removable Studs, Cogs, or
Toe Pieces for Horse-shoes.
I, GEORGE HENRY DUDLEY, of Broadfield House, Kingswinford, near Dudley,
Staffordshire, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
-
The object of this invention is to facilitate the removal from horse shoes of those
studs, cogs or toc pieces (hereinafter all referred to as studs or cogs) which are
provided with a taper shank which is driven into a hole in the shoe.
In carrying out my invention the head of the stud or cog is made larger than the
shank part as is usual so as to form a shoulder at the sides of the shank but instead
of making the top of this shoulder flat as heretofore I make it rounded or inclined
preferably froin the centre of the stud towards the sides so that when the wedge
shaped tool hereinafter described is driven between the shoulder and the shoe the said
tool will bear upon the centres of the shoulders and extract the stud or cog from
the shoc.
The improved tool which I use for extracting the said studs or cogs from the shoe,
and which can also be used with shouldered studs or cogs of the ordinary kind, is
provided with two prongs at one end each prong being in the form of a wedge and
the other end of the tool is suitably formed for being struck with a hammer.
The studs or cogs are extracted from the shoe by inserting the ends of the prongs
between the shoulders of the stud or cog and the shoe, the shank of the stud or cog
being between the prongs.
Instead of the shoulders of the studs or cogs being inclined or rounded from the
centre of the stud or cog towards the sides thereof they may be rounded or inclined
from one side of the stud or cog to the other but the former method is preferable as
it enables the extracting tool to be used at either side of the stud or cog; or for
the same purpose the shoulders of the stud or cog may be pointed.

COMPLETE SPECIFICATION (AMENDED).
Improvements in and connected with Removable Studs, Cogs, or
Toe Pieces for Horse-shoes.
1, GEORGE HENRY DUDLEY, of Broadfield House, Kingswinford, near Dudley,
Staffordshire, 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 this invention is to facilitate the removal from horse-shoes of those
studs cogs or toe pieces (hereinafter all referred to as studs or cogs) which are
provided with a shank usually made taper which is driven into a hole in the shoe.

page_text: In carrying out my invention the head of the stud or cog is made larger than the
shank part as is usual so as to form a shoulder at the sides of the sbank, but instead
of making the top of this shoukler flat as heretofore I make it rounded or inclined,
preferably from the centre of the stud towards the sides, so that when the wedge
shaped tool hereinafter described is driven hetween the shoulders and the shoe the
said tool will bear upon the shoulders and extract the stud or cog from the shoe.
The improved tool which I use for extracting the said studs or cogs from the
shoe, nud which can also be used with shouldered studs or cogs of the ordinary
kind, is provided with two prongs at one end each prong being in the form of a
wedge and the other end of the tool is suitably formed for being struck with a
bammer. This tool forms no part of this invention.
The studs or cogs are extracted from the shoe by inserting the ends of the prongs
between the shoulders of the stud or cog and the shoe, the shank of the stud or
cog being between the prongs.
Instead of By the shoulders of the studs or cogs being inclined or rounded from the
centre of the stud or cog towards the sides thereof, they may be rounded or inclined
from-one-side of the stud or cog to the other, but the former-method is preferable
as it enables as abore described the extracting tool to can be used at either side of the
stur! or cog, er for-the-same-purpose the shoulders of the stud or cog may be pointed.
and the said tool acts in a direct line with the shank of the stud or cog.
On the accompanying drawings Fig. 1 represents in side clevation and Fig. 2 in
front elevation and in plan a stud or cog constructed according to this invention;
Figs. 3 and 4 shew the same fixed in part of a horse shoe; Figs. 5 and 6-shew-a
modification of my invention in side and front elevation-respectively; Fig. 7
represents a further-modifiention Figs. 8 and 9 shew a further modification in side
and front elevation respectively; and Fig. 10-shews a further modification, Fig. 11
represents the improved tool which I employ for extracting my improved studs cogs
or toe-pieces, and Fig. 12 shews how the said improved tool is used; and Fig. 13
shews in side elevation and Fig. 14 in front elevation a toe-piece constructed according
to this invention.
The same letters of reference indicate the same or corresponding parts in all the
Figures of the drawings.
a is the head of the stud cog or toe-piece and is the usual square taper shank of
the same represented in Figs. 3, 4, 13 and 14 as fitting in a hole in part of a
horse-shoe marked e. The shoulder or shoulders at the sides of the shank are
marked and, as will be seen, they are either rounded towards both sides.
(Figs. 1, 2, 3, 4, 13 and 14) or-rounded towards one-side-only (Figs. 5 and 6)
or inclined towards both sides (Figs. 8 and 9) or inclined towards one-side only
(Figs. 7-and-10) so as the better to enable the wedge shaped extracting tool to
be driven in between the shoulders and the shoe and to take a proper central bearing
on the shoulder to extract the stud or cog as hereinafter described. g¹ g² are the two
wedge shaped prongs of the extracting tool f (Fig. 11) and is the end which is
formed for being struck with a hammer. This tool is used for extracting a stud,
cog or toe piece (see Fig. 12) by driving the wedge shaped prongs g' g of the tool at
cach side of the shank b between the shoulders c and the shoe e.
The shank is by preference made so large that when the stud, cog or toe-piece
is driven into the shoe the shoulders c will not quite touch the same so as to leave
more room for the extracting tool to be driven in.
My invention is applied to other studs, cogs or toe-pieces having round, oval or
other shaped shanks, or square or other shaped heads similarly as above described and
illustrated as applied to those having square shanks and chisel shaped heads.
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. In removable studs cogs or toe-pieces which are constructed to be affixed to
horse shoes by being driven into holes therein, forming a rounded, or double inclined.

page_text: er-pointed shoulder or shoulders c at the sides of the shank to facilitate the insertion
of a wedge shaped extracting tool between the head of the stud cog or toe-piece and
the underside of the shoe for the purpose and substantially as hereinbefore described
and illustrated in the accompanying drawings.
2. The improved extracting tool/ provided with the forked wedge-shaped end gly
for-extracting studs cogs or toe pieces from horse-shoes-substantially ns-hereinbefore
described and illustrated by Figs. 11-and 12 of the necompanying drawings.
