Complete Specification Accepted, 5th Feb., 1889
I HENRY WISKEN of Hazlethorpe Heywood Lancashire, Surgeon do hereby declare
the nature of this invention to be as follows:-
This invention relates to appliances to be attached to horse shoes to prevent them
from slipping, also to prolong the wear of such shoes.
To carry out this invention 1 form rectangular slots in the toes and heels of horse
shoes, into each of which I fit the top part of a metal stud such part being also
rectangular, the other part projects outwards, from the bottom of the shoo to a sharp
angle.
At or about the centre of one side of the rectangular part of the metal stud a groove
is formed to receive the end of a screw or screws which passes or pass through the
side or end of the shoe, to which it is thereby firmly secured.
In place of the angular projections hereinbefore mentioned I may form them
rectangular.

I, HENRY WISKEN, of Hazlethorpe, Heywood, Lancashire, Surgeon, do hereby
declare the nature of this invention and in what manner the same is to bu
performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to improvements in that type of horse shoe in which
independent cogs, too pieces, heel picces or other projections are attached to the face
of the shoes to afford a firmer foothold, provent slipping and also to prolong the wear
of the shoe, and the object of the said invention is to provido a simple and effective
mnothod of securing such independent projections to horse shoes, which allows them to
be readily removed without removing the shoe or exchanged for frost cogs or other
form of projections by an unskilled person.
•
Such projections are commonly provided with screw tenons screwing into holes in
the shoo or a slightly taper tenon is formed on each projection, generally of
rectangular section, and driven tightly into a correspondingly shaped mortise in the
shoo. In order to prevent these projections shaking loose and being lost out, it is
necessary to scrow or drive them in very tight and consequently when any change is
required to be made or frost cogs put in special appliances or considerable skill
is necessary to remove them, particularly if they are much worn.
My said improvements consist in the devices hereinafter described for securing or
locking the said tenons in the mortices.
For this purpose to fully describe my invention reference is to be had to the
accompanying sheet of drawings forming a part of this specification in which similar
letters of reference indicate corresponding parts in each of the figures.
Figure 1, represents a perspective view of the underside of a horse shoe provided
with loose cogs secured in accordance with my invention. Figuro 2 is a side view.
Figuro 3 is a front view of the same. Figure 4 is a full view of the under side
of the shoe without the cogs. Figures 5 and 6 are views at right angles to each
other of frost too cogs and figure 7 is a perspective view of a rectangular or blunt rear
or heel cog.
The cogs A are provided with tenons B fitting comparatively loose in the mortise C
formed in the shoe D. Screws E screwing into the holes F pass at right angles
through each of the tenons B and securely fix the cogs in position entirely obviating
the possibility of loosing them in use. The screws E preferably pass entirely through
the hole G in the tenons but it is obvious that a transverse notch, groove or other
depression may be formed in the tenon to receive the point of the screw and
prevent the cog being withdrawn. It is obvious that when it is desirable to renew
or change the cogs the screw E may be readily removed and the cogs taken out and
replaced by new ones.
Instead of screws 1 may employ pins to pass transversely through the tenons of the
cogs. In this case split pins are preferably employed and those fixing the heel cogs
pass through the shoe in the direction represented by the pin H figure 4.

page_text: Blunt or rectangular cogs similar to A¹ figures 1 and 7 or any other form of cog
or projection may be secured in the above described manner to horse shoes and it
is not essential especially in regard to the heel cogs for the tenons to be of rectangular
section.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what I
claim is:
The combination with a horse shoe having one or more independent cogs or other
similar projections, of a screw or pin, or screws or pins, arranged to pass transversely
through the tenon or tenons of said cog or cogs and thereby hold same in position,
substantially as herein shown and described and illustrated in the accompanying
drawings.
