PROVISIONAL SPECIFICATION.
Improvements in Horse-shoes.
We GEORGE WILLIAM ALCOCK of Attercliffe Sheffield in the County of York
Grocer and JOSEPH OATES of Springvale Road Sheffield aforesaid Commercial
Traveller do hereby declare the nature of this invention to be as follows:-
Our present invention relates to those kind of horse shoes which are arranged
with attachable or removable calks or projections and has for its object the better
securing of the said calks or projections to the shoe-plate for which purpose we
form the shoe plate of the ordinary pattern and arrange a square or other suitable
hole vertically through it at each part where it is required to fit or fix an attachable
calk or projection for instance it is usual to wear a toe projection and two heel
projectious or calks and where each of these are situated under the shoe in the form
of attachable calks we form a hole vertically through the shoe. Each said vertical
hole receives a stem which is arranged on each projection for the purpose.
On either side of each vertical hole in the shoe-plate is arranged a lug one said
lug has an oblong parallel hole formed laterally through it and the opposite lug has
a lateral tapering hole.
An oblong parallel hole is also formed through the stem of each calk or
projection corresponding to the parallel hole in the lug.
When the calk or projection is fitted to the shoe-plate the parallel and tapered
lateral holes in the lugs come in line with the lateral hole in the stem of calk or
projection and in order to fix said calk or projection firmly and securely to said
shoe-plate we employ a specially formed key one part of which fits in the parallel
hole in the lug and stem of calk or projection and the other part of said key is
arranged with two spring prongs which spring outwards and press on the sides of
the tapered oblong hole in the opposite lug. Each said key is preferably composed
of steel and the parallel portion thereof is hardened while the pronged part is
tempered in order to give it the required elasticity or spring. It is advisable to
drive each key in from the outside edge of shoe. The pronged ends of the key are
first pressed towards each other and placed into the oblong hole on the side of shoe
or outer lug and subsequently the key is driven home with force the pronged ends
thereof automatically opening to fill up the tapered hole in opposite lug formed on
the shoe plate as will be well understood.

COMPLETE SPECIFICATION.
Improvements in Horse-shoes.
We GEORGE WILLIAM ALCOCK of Attercliffe Sheffield in the County of York
Grocer and JOSEPH OATES of Springvale Road Sheffield aforesaid Commercial
Traveller 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:--
Our present invention relates to those kind of horse shoes which are arranged
with attachable or removable calks or projections and has for its object the better
securing of the said calks or projections to the shoe-plate for which purpose we
form the shoe plate of the ordinary pattern and arrange a square or other suitable
hole vertically through it at each part where it is required to fit or fix an
attachable calk or projection for instance it is usual to wear a toe projection and

page_text: two heel projections or calks and where each of these are situated under the shoe
in the form of attachable calks we form a hole vertically through the shoe. Each
said vertical hole receives a stem which is arranged on each projection for the
purpose.
On either side of each vertical hole in the shoe plate is arranged a lug one said
lug has an oblong parallel hole formed laterally through it and the opposite lug has
a lateral tapering hole.
An oblong parallel hole is also formed through the stem of each calk or
projection corresponding to the parallel hole in the lug.
When the calk or projection is fitted to the shoe-plate the parallel and tapered
lateral holes in the lugs come in line with the lateral hole in the stem of calk or
projection and in order to fix said calk or projection firmly and securely to said
shoe plate we employ a specially formed key one part of which fits in the parallel
hole in the lug and stem of calk or projection and the other part of said key is
arranged with two spring prongs which spring outwards and press on the sides' of
the tapered oblong hole in the opposite lug.
Each said key is preferably composed of steel and the parallel portion thereof is
hardened and the pronged part is tempered in order to give it the required
elasticity or spring.
It is advisable to drive each key in from the outside edge of shoe. The pronged
ends of the key are first pressed towards each other and placed into the oblong
hole on the side of shoe or outer lug and subsequently the key is driven home with
force the pronged ends thereof automatically opening to fill up the tapered hole' in
opposite lug formed on the shoe plate.
In order that our said invention may be fully understood and readily carried
into effect we will proceed to further describe the same by the aid of the
accompanying drawings in which Fig. 1 is a side elevation and Fig. 2 an inverted
plan of a horse shoe constructed in accordance with our invention and Fig. 3 is a
side elevation of part of shoe illustrating a modification.
Similar letters of reference denote corresponding parts in each view.
The shoe plate A is arranged with vertical holes B at each part thereof where it
be required to fit or fix an attachable calk or projection C.
Each hole B receives a stem c¹ which is arranged on each projection or calk C.
The shoe plate A is arranged with lugs D and D₁ and through each lug D is a
parallel hole oblong in cross section and through each lug D' is a tapering hole e¹
also oblong in cross section and corresponding in a horizontal plane with the
hole e.
An oblong parallel hole fis also formed through the stem c¹ of each calk C and
said hole comes in the same horizontal plane between the holes e¹ and e.
When the projection c¹ is fitted to the shoe plate the parallel and tapered lateral
holes e and e¹ in the lugs come in line with the lateral hole f formed in the stem of
calk or projection c¹ and in order to fix said calk or projection C firmly and securely
to the shoe plate A we employ a specially formed key G the part g of which fits
into the parallel holes e and fand the part g' is arranged with two prongs which
spring outwards and press on the sides of the tapered oblong hole e¹ in the lug D¹.
Each said key G is preferably composed of steel and the parallel portion 9 thereof
is hardened while the pronged part g is tempered in order to give it the required
elasticity or spring.
Each key G is driven into the shoe plate C from the outside edge of shoe.
The pronged ends g of the key G are first pressed towards each other and
placed into the oblong hole e formed in the outer lug D and subsequently the said
key G is driven home with force when the pronged portion g thereof automatically
opens out so as to fill up or press against the tapered sides of the hole e¹ in
lug D¹.
In the modification shown at Fig. 3 this is the arrangement we prefer to adopt
where the shoe plate C is stamped or forged out of steel or other malleable
metal.

page_text: The lugs D and D¹ are arranged with gaps at the upper sides of which the
key G bears. The stem c¹ of calk C is made in the manner hereinbefore
described.
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. In horse shoes arranged with attachable or removable calks or projections C
the combination with oblong parallel and tapered holes e, f and e¹ of a key G
arranged with a hardened parallel portion g and a pronged tempered portion g
substantially as described and used for the purpose specified.
