Brewer, and WILLIAM SEEDHOUSE, Bolsover Street, Sheffield aforesaid, Manufacturer
do hereby declare the nature of this invention to be as follows:-―
This invention relates to improvements in the method of attaching or securing
Calks, Studs and frostbits to Horseshoes; the object being to combine simplicity and
efficiency.
We make the Horseshoe with suitable openings or recesses to receive the shanks of
the calks, studs or frostbits; thus we prefer to make one at each heel end of the shoe,
and two near together at the toe.
They may be of any desired shape to receive the shank of the calk or stud or frost
bit, such as square, oval, or round, and they are better to be slightly tapered to match
the tapered shanks, so as to ensure a fit.
The shoes are preferably made in malleable cast iron, and a cotter hole is cast
horizontally through the side of the shoe, alongside and opening into the hole for the
stud or calk.
The shank of the calk, stud or frost bit is made with a shallow groove or keyway,
a little way below the head, into which the edge of the cotter or key cakes, when driven
into position in the Cotter hole before mentioned.
We form the cotter hole at the toe of the shoe between the two stud openings, and
50 that the one cotter will engage with the shanks of both studs or calks or frostbits,
thus if one side is worn quicker than the other, that side calk can be replaced
without removing the other, which is an advantage.
The cotter we prefer to use is flat, (say for example x or thereabouts,) and
either solid or split as desired, but round split pins may be used if preferred.

Improvements in Attaching Calks, Studs, and Frostbits to Horse
Shoes.
We ALBERT LUKE LADE of Eldon Street Sheffield in the County of York Brewer,
and WILLIAM SEED HOUSE Bolsover Strect Sheffield aforesaid 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 an improved method of attaching or securing calks,
studs, and frostbits to Horse Shoes; the object being to combine simplicity and
efficiency.
And in order that our invention may be clearly understood we annex a sheet of
drawings illustrating same.
Fig. 1, represents a Horse shoe, and the method of securing the calks or studs.
Fig. 2, side view of same.
Fig. 3, front view of same.
Fig. 4, elevation of a toc calk.
In carrying out our invention we make the Horse Shoe with suitable openings A,
to receive the shanks of the calks, studs, or frost bits B, thus for example we make
two openings at the toe and one at each heel-end of the shoe.
The said openings and the shanks of the calks may be of any suitable shape, such
as round, square, octagonal, or like shape, those shown in the drawings being
square, but we prefer to make them slightly tapered, so that there may be no
slackness of fit.
We preferably make the shoe by casting it in steel or in malleable cast iron, and we
cast a cotter hole horizontally through the side of the shoe, so as to pass through
one side of each of the said openings for the calk shanks; those for the heel calks are
marked C, and that for the toebit is marked D.
We prefer to make the toebit with two shanks such as shown in Figs. 3 & 4, on
account of its greater width, and in the side of each shank we make a shallow slot
clearly seen in Fig. 4; similar slots are made in the side of the single shank calks ;
when the calk is put into the shoc a cotter E, is driven into the cotter hole and
through the slot in the shank of the Calk or stud, which effectually prevents it turning
round or becoming loose.
The Cotters may be solid or split, oblong or round, and of any suitable material, as
desired.
It will be seen that the cotter hole for the toebit is made between the shanks,
thus one cotter will engage with both shanks of the bit but instead of a single
bit, two separate bits may be used, the shanks being secured by a single cotter in the
way described.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1-The improvements in attaching Calks, Studs, and frost bits to horse shoes,
substantially as herein before described and as illustrated in the drawings.
2-In attaching studs and frost-bits to Horse shoes, passing a cotter through the
shoe and through a groove or slot in the side of the shank of the stud or frost bit
substantially as described and shown.
