PROVISIONAL SPECIFICATION.
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 pro-
vided 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 or shoulders at the sides of the shank,
but in addition to the usual shoulders I form a set-off, or lateral projecting part at
one or more of the sides or corners, or sides and corners, of the shank between the
usual shoulders and the end of the shank so that when the stud or cog is driven into
the shoe the said set-off or lateral projecting part or parts will, by bearing against the
underside of the shoe, ensure an open space or open spaces being left between the
underside of the shoe and the usual shoulder or shoulders, so that the wedge shaped
tool hereinafter described can be driven between the shoulder or shoulders and the
shoe so as to extract the stud or cog therefrom.
Instead of employing an additional set-off or lateral projecting part or parts as
above described, one or more of the usual shoulders may be formed nearer to the end
of the shank than the others so as to enable a wedge shaped extracting tool to be
inserted between the said other shoulders and the underside of the slioc as above
described.
The shoulders on the stud or cog against which the extracting tool bears may eithor
be flat as usual or rounded or inclined, either from the centre of the stud or cog
towards the sides, or from one side of the stud or cog to the other, so as the better
to enable the said wedge shaped extracting tool to be driven in between the shoulder
and the shoe and to ensure the extracting tool bearing centrally upon the shoulder or
shoulders; or for the same purpose the shoulders of the stud or cog may be pointed;
and in some cases, when the shoulders are made rounded, inclined or pointed as above
described, the said additional set-off or lateral projecting part or parts on the shank
may be dispensed with.
In some cases, as in very wide toe-pieces, I form a cross groove in the shoulder at
one or both sides of the shank into which the extracting tool can be driven in
extracting the toe-piece as above described.
The improved tool which I use for extracting the said studs or cogs from the shoe,
and which can also be used with shouldered cogs or studs 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 driving the wedge shaped prongs
of the tool between the shoulders of the stud or cog and the shoe, the shank of the
stud or cog being between the prongs.

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 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 taper shank which is driven into a hole in the shoe.
I will describe my invention by referring to the accompanying drawings on which
Fig. 1 illustrates in side elevation, Fig. 2 in front elevation and in plan a stud or cog
constructed according to this invention; Fig. 3 represents a modified form of the
same Fig. 4 represents a further modified form; Fig. 5 represents in front elevation
and Fig. 6 in side elevation a further modification; Fig. 7 is a further modification;
Figs. 8 and 9 shew the stud or cog illustrated by Figs. 1 and 2 fixed in position in
a horse-shoe; Fig. 10 represents in side elevation and Fig. 11 in front elevation a
further modification of my invention; Figs. 12 and 13 shew a further modification;
Fig. 14 illustrates an improved extracting tool for use with studs cogs or toe-pieces;
Fig. 15 illustrates how the said tool is used; and Fig. 16 illustrates in side elevation
and Fig. 17 in front elevation a wide toe-piece constructed according to this invention
and Fig. 18 is another form of the same.
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 taper shank of the
same. In carrying out my invention the head a of the stud or cog is made larger
than the shink part has is usual so as to form a shoulder or shoulders marked cat
the sides of the shank, but in addition to these shoulders I form a set-off or lateral
projecting part & at one or more of the sides or corners or sides and corners of the
shank between the shoulders c and the end 6' of the shank so that when the stud or
cog is driven into the shoe (see Figs. 8 and 9) the said set-off or lateral projecting part
or parts d will by bearing against the underside of the shoe (part of the shoe is shewn
and marked e) ensure an open space or spaces being left between the underside of the
shoe and the shoulder or shoulders e so that the stud or cog can be extracted by the
improved extracting tool fillustrated by Fig. 14.
The said tool which I use for extracting my improved 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 marked gl g² at one end each of these prongs being in the
form of a wedge and the other end h of the said tool is suitably formed for being
struck with a hammer. The studs or cogs are extracted from the shoe by driving the
wedge shaped prongs g¹ g² of the tool between the shoulders c of the stud or cog and
the shoe as shewn by Fig. 15 the shank b of the stud or cog being between the
prongs g³ g³.
The shoulders c on the stud or cog against which the extracting tool bears may
either be flat as is usual or of other form so as to enable the extracting tool to be
inserted between the shoulders and the underside of the shoe; for instance the
shoulders c may be rounded towards both sides as illustrated by Figs. 1 and 2, or
rounded towards one side only as illustrated by Fig. 3; or they may be inclined on
one side as shewn by Fig. 4, or inclined on both sides as shewn by Figs. 5 and 6, so
as to form pointed shoulders, or inclined right across the shoulder from one side to
the other as shewn by Fig. 7; so as the better to enable the wedge shaped extracting
tool to be driven in between the shoulder and the shoe and to ensure the extracting
tool bearing centrally upon the shoulder or shoulders. When the said shoulder or
shoulders is or are made rounded inclined or pointed as above described the additional
set-off or lateral projecting part or parts d may if preferred be dispensed with, as in

page_text: the example illustrated by Figs. 10 and 11, as the shape of the shoulder or shoulders
will enable the extracting tool to be inserted between them and the underside of
the shoe.
When the stud cog or toe-piece is made very wide as in the toe-piece illustrated by
Figs. 16 and 17 I prefer to form a cross groove i in the shoulders at one or both
sides of the shank into which the extracting tool can be driven in extracting the
toe-piece as above described.
The stud or cog illustrated by Figs. 12 and 13 is made without any additional
set-off or lateral projecting part or parts d and the shoulders c are made flat as usual
but one or more of the shoulders marked c' is or are formed nearer to the end of the
shank than the others so as to enable the wedge shaped extracting tool to be
inserted between the shoulders c and the underside of the shoe for extracting the
stud or cog as above described.
It will be evident that my invention can be applied to all other kinds of studs cogs
or toe-pieces which are made to drive whether their shanks are round oval or of other
shape similarly as above described and illustrated with reference 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 those removable studs cogs or toe-pieces which are constructed to be affixed
to horse-shoes by being driven into holes therein, forming a set-off or lateral pro-
jecting part at one or more of the sides or corners or sides and corners of the shank
between the usual shoulder or shoulders and the end of the shank, so as to ensure a
space or spaces between the said shoulder or shoulders and the underside of the shoe
when the stud cog or toc-piece is driven therein, for the purpose and substantially as
herein before set forth.
2. 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 inclined or pointed
shoulder or shoulders c at the sides of the shank, and with or without one or more
sets-off d between the shoulder or shoulders c and the end 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 herein-
before described and illustrated in the accompanying drawings.
3. A removable taper shanked stud cog or toe-piece for horse-shoes having a
groove i across one or more of its shoulders for the purpose and substantially as
herein before described and illustrated by Figs. 16 and 17 of the accompanying
drawings.
4. The improved tool f for extracting studs cogs and toe-pieces from horse-shoes
provided with a forked wedge shaped end for the purpose and substantially as herein-
before described and illustrated by Figs. 14 and 15 of the accompanying drawings.
Dated this 3rd day of January 1896.
