PROVISIONAL SPECIFICATION.
Improvements in Roughing Cogs and Toe Pieces for Horse Shoes
and Mule Shoes.
I, BENJAMIN WATKINS, of Peers Cottage, Penzer Street, Kingswinford, near
Dudley, Worcestershire, Nail Merchant, do hereby declare the nature of this
invention to be as follows:-
This invention consists in the hereindescribed improvements in roughing cogs
and toe pieces for horse shoes and mule shoes.
Heretofore it has been customary to make each of the said roughing cogs with a
shank, either square or round or of other form which has entered a corresponding
hole in the horse shoe or mule shoe and been there secured to the shoe in various
ways; and in some instances toe pieces have been made with two of these shanks
engaging in corresponding holes in the shoes. It is well known that unless very
carefully made the said roughing cogs and toe pieces formed with a shank or shanks
engaging in a hole or holes in the shoe as above referred to are liable to become loose
and detached from the shoe.
This defect it is the object of my invention to overcome.
In a roughing cog or a toe piece formed according to my invention the shank
or shanks of the cog or toc piece is or are prolonged in the form of the shank of
a horse nail which is driven through the shoe into the hoof and clenched over like a
horse nail thus making the roughing cog or toe piece very secure.
The shank or
shanks proper of my improved cog or toe piece is or are of about the usual size and
of round square or other suitable cross section fitting in a corresponding hole or
holes in the horse shoe or mule shoe and the said prolongation is reduced in cross
section and tapered and pointed to about the same shape and length as the shank
of a horse nail.
My improved cogs and toe pieces can be made of either steel or iron or other
suitable metal or alloy and when made of the former metal the wearing end is
hardened and the shank is tempered so as to be pliable for clenching.
Sometimes instead of making the nail like prolongation to each of the shanks of
a toe piece I make the said prolongation to only one of the said shanks.

Improvements in Roughing Cogs and Toe Pieces for Horse Shoes
and Mule Shoes.
I, BENJAMIN WATKINS, of Peers Cottage, Penzer Street, Kingswinford, near
Dudley, Worcestershire, Nail Merchant, 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 consists in the hereindescribed improvements in roughing cogs
and toe pieces for horse shoes and mule shoes.
Heretofore it has been customary to make each of the said roughing cogs with
a shank, either square or round or of other form which has entered a corresponding

hole in the horse shoe or mule shoe and been there secured to the shoe in various
ways; and in some instances toe pieces have been made with two of these shanks
engaging in corresponding holes in the shoes. It is well known that unless very
carefully made the said roughing cogs and toe pieces formed with a shank or shanks
engaging in a hole or holes in the shoe as above referred to are liable to become
loose and detached from the shoc.
This defect it is the object of my invention to overcome.
I will describe my invention by referring to the accompanying drawings.on
which
Figure 1 represents in front and side elevations a roughing cog or toe picce
made according to this invention and furnished with one shank;
Fig. 2 shews similar views of a modification of the same made with two shanks; .
Fig. 3 is another form of the same;
Fig. 4 represents in front and side elevation another form of the said toe piece;
and
Fig. 5 shews by similar views another form of the same;
Fig. 6 represents in front and side elevations a cog made according to this
invention which is suitable only for fixing to the heel part of the shoes; and
Fig. 7 is a modified form of the same;
Fig. 8 is a further modification;
Fig. 9 is a side elevation, Fig.10 a front elevation and Fig. 11 an inverted plan
of a horse's hoof with shoe attached and provided with a toe piece like that shewn
by Fig. 4 and a cog like that shewn by Fig. 6.
The same letters of reference indicate the same or corresponding parts in all the
figures.
That part of the cog or toe piece which projects below the shoe (and which is
usually made chisel pointed) is marked a and the shank or shanks of the same
which engages or engage in a corresponding hole or holes in the shoe is or are
marked b.
The
In a roughing cog or toe piece formed according to my invention the usual shank
or shanks 6 of the cog or toe pieces is or are prolonged at c in the form of the shank
of a horse shoe nail which is driven through the shoe d into the hoof and clenched
over like a horse nail thus making the roughing cog or toe piece very secure.
shank or shanks proper marked b of my improved cog or toe piece is or are of
about the usual size and of round (Fig. 4) square (Figs. 1, 2, 3, 5, 6, 7 and 8)
or other suitable cross section fitting in a corresponding hole or holes in the
horse shoe d or in the mule shoe and the said prolongation c is as shewn reduced
in cross section beyond the shank or shanks proper b and tapered and pointed to
about the same shape and length as the shank of a horse nail.
My improved.cogs and toe pieces can be made of either steel or iron or other
suitable metal or alloy and when made of the former metal the wearing end a is
hardened and the nail like shank c is tempered so as to be pliable for clenching.
As before stated my improved roughing cogs and toe pieces can be made cither
with one shank (Fig. 1) or with two shanks 6 (Figs. 2, 3, 4, 5, 6, 7 and 8).
When, as shewn in these latter figures, the cogs or toe pieces are long I prefer two
shanks so as the better to prevent the cog or toc piece twisting in the shoe.
7
Sometimes instead of making the nail like prolongation c to each of the shanks b
of a toe piece (see Fig. 3) I make the said prolongation c to only one of the said
shanks as shewn in Figs 2, 4, 5, 6, and 7.
The accompanying drawing shews what I consider to be the best way of carrying
my invention into practice but it is to be understood that my invention is not limited
to the precise forms of cogs and toe pieces shewn.
I am aware that prior to this invention horse shoe nails have been made with
large heads shaped to serve as roughing cogs but these, not having been made
with the enlarged shanks b, as hereindescribed, have been liable to break when
in use, the head breaking off the shank.

page_text: 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 improvements in roughing cogs and toe pieces for horse shoes and
mule shoes herein before described and illustrated by the accompanying drawing,
consisting in prolonging one or more of the shanks b of a roughing cog or toe piece
in the form of the shank of a horse shoe nail c, for the better securing of the cog
or toe piece to the shoe, substantially as herein before set forth.
2. The improved roughing cogs and toe pieces for horse shoes and mule shoes
made in the various forms hereinbefore described and illustrated by the accompanying
drawing.
