Improvements in Horse Shoes.
THOMAS CALVERT CLAYTON, Merchant Starkie House Adlington near
Macclesfield & FREDERICK WRIGHT, Coachman c/o the above do hereby declare
the nature of this invention to be as follows:-
An invention for the convenient & economical sharpening or roughing of horse-
shoes to give horses a firm foothold on slippery ground. We propose to make
horse-shoes in 2 parts, one part we call the false shoe, this is attached to the hoof
by nails in the usual manner. The second part or treading shoe hereinafter culled
the "tread" is attached to the false shoe by three or more screws, the heads of
which are countersunk below the metal of the tread. In the tread are four slots,
the sides of which are bevelled so that the diameter next to the false shoe is
greater than that next the floor. Before the tread is screwed on to the false shoc,
4 pieces of iron or steel, the exact length of the slots, & the transverse section of
which is an equilateral triangle, are placed in the slots so that one angle of the
triangle rests on the ground & the side subtending this angle is level with the
upper surface of the tread.
The tread is then screwed on to the false shoe & the triangular sharps are then
quite secure. The three sides of the sharps are scored with parallel lines, similar
to those on a file. When one edge of the sharp is, worn, the second can then be
used & then the third. Thus one sharp can be used three times with a minimum
of labour.
The shoes may be used without the sharps, or, the slots may be filled in with
wedge shaped blocks of india rubber or steel, or iron wedges with blunted edges.
The vital point of our invention is the use of the triangular sharps.
The invention is equally applicable to light or heavy horseshoes.

COMPLETE SPECIFICATION.
Improvements in Horse Shoes.
We THOMAS CALVERT CLAYTON and FREDERICK WRIGHT of 30 Pall Mall,
Manchester in the County of Lancaster 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 and accompanying
drawings:-
"
Our said invention relates to an improved description of horse shoc suitable for
use in frosty or slippery weather. The chief feature of our invention is that we
are enabled to apply and renew the "sharps" or anti-slipping pieces of the shoe in
an economical manner and with but little expenditure of time and trouble. We
form our improved shoe in two halves or thicknesses and confine the said " sharps
between the two halves which are secured together by means of countersunk
screws. The "sharps" are of a triangular shape one apex of each "sharp" pro-
jecting above the level of the confining plate. By separating the halves of the
shoe and turning the "sharps" round so as to expose a new angle we obtain what
is practically a new “sharp."

page_text: The invention will be best understood by a reference to the annexed 'sheet of
drawings which clearly illustrates our invention.

Fig. 1 is a plan view of the lower half or tread plate through which the
sharps" project.

Fig. 2 is a cross section of the shoe at the line A. B. Fig. 1. .
Fig. 3 is a similar cross section at the line C. D. Fig. 1.
Fig. 4 is a cross section at the line E. F.
Fig. 5 is a separate cross section of the sharp.
Figs. 6 and 7 illustrate the method of fixing the holding screws in place to
prevent them from working loose.
As already said the shoe is composed of two plates or halves a and b. The
first or base plate a is fixed by nails or other means to the hoof in the ordinary
manner. The second or cover plate bis fixed to the half a by means of screws c
the heads of which occupy countersunk recesses in the cover plate b as clearly
shown in Fig. 3. Where the screws c unite the two halves together we preferably
form a slight elevation or thickness on the base plate a and form a corresponding
recess in the cover plate 6 as shown at Fig. 7. Thus we secure a more extended
holdfast for the screws c and also in a measure interlock the two halves of the shoe
together and prevent the screws c from being sheared by longitudinal shocks and
strains. To prevent the screws from working loose we cut a nick in the side of
the screw and form a small keyway in the halves of the shoe through which we drive
a tapered cottar d, the narrow end being hammered down into a recess in the upper
half or base plate a (see Figs. 3 and 7). Thus the cottar d cannot drop out and
the screw being locked by the cottar cannot work loose."
We
In the cover plate we form slots at e e, Fig. 1, the said slots tapering inward
and downward as clearly shown in the sectional view Fig. 4. In conjunction with
these slots we use "sharps" which consist of short lengths of hardened steel
triangular in cross section as shown in Figs. 4 and 5. When combining these
"sharps" with the shoe, we first place the "sharp "fupon the base plate a.
then superpose the cover plate b causing the apices of the triangular "sharps" to
project through the tapering slots at e, as plainly shown at Fig. 4. The base and
cover plate are then secured together by means of the screws c and the shoe is
ready for use.
"
As regards the rear calks g which appear in Fig. 1 and in cross section in Fig. 2
they are applied in a manner precisely similar to the mode in which the "sharps
are combined with the shoc and simultaneously therewith. These calks g might
be of the same form as the " sharps" and of the same material or they might be
of the form indicated in the drawings and might be of vulcanised rubber or other
suitable anti-slipping or elastic material. In some instances the employment of
separate calks might be dispensed with and the calks formed by welding,
forging or forming immovable calks upon the rear tips of the cover plate b as in
the case of ordinary shoes.
It will now be readily apparent that when the " sharps" have become worn and
ineffective it is an easy matter to renew their efficiency by removing the cover
plate and turning the sharps so as to present fresh and unworn apices. The
calks g may also be renewed by placing fresh calks in the shoe when the old ones
are worn out. The illustrated forms of the "sharps" and calks might be varied
to some extent. When the "sharps are not required the shoe may be applied
and worn without the "sharps" and the calks 9 can also be changed and adapted
to suit circumstances.

The halves comprising the base and cover plates of the shoe might be forged,
stamped or cast in the required shapes and sizes.
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 the construction of a horse shoe for use in frosty and slippery weather the

page_text: "
combination of two separate halves comprising a base and a cover plate, the latter
being secured to the former by means of screws and formed with slots or apertures
so as to admit of the application of triangular or other suitably shaped "sharps
and removable calks which can be turned, changed and renewed by removing the
cover plate substantially as and in the manner hereinbefore described and shown.
2. In combination with a shoe of the indicated description the triangular
"sharps" capable of being turned so as to present in succession the unworn apices
to the road for the purposes and substantially as described and shown.
3. In a shoe of the indicated nature the method of preventing the screws which
secure the cover and base plates together, from working loose substantially as
described and shown.
