PROVISIONAL SPECIFICATION.
Improvements in Shoes for Horses and other Animals of Draught
or Burden.
I, GEORGE EDWARD PRITCHETT, of Oak Hall, Bishop's Stortford, in the
County of Hertford, Architect, do hereby declare the nature of my invention to
be as follows:-
My invention relates to improvements in shoes for horses and other animals of
draught or burden, and its object is to make provision for the shoe automatically
acquiring a trustworthy grip of the ground from the moment the foot is down,
without exacting any extra effort or attention from the animal.
In carrying my invention into effect, I slot or form sinks or mortices in the shoe,
either in front or at either or both the sides, and in the slot or its equivalent I
pivot, in a more or less loose manner, a biting device consisting of a toothed plate,
or a strip of metal, or piece of wire, bent so as to present one or more points of
contact or bearing surfaces to the ground.
The object and intention of having the point or points of contact is to provide
for the shod hoof being in operative contact with, or biting, the ground in spite of
any irregularity in its surface. The biting device at the side of the shoe is or may
be pivotted to a clip suitably positioned on the shoe to receive it. There may be
as many clips as may be necessary so fitted each with a biting device. It will be
seen that as a supporter of the biting device, the clip is the equivalent of the slot
above mentioned. When a clip is so used, the biting device is pivotted upon it
from the outside, by a suitable pivotal pin or screw, and the teeth of the said device
are crooked inwards so as to pass downwards through the shoe. A side biting
device such as last described, may be fitted to the front clip, or, on the other hand,
a biting device such as that first described may be fitted to the side of the shoe.
It will be obvious that the fixation of a biting device may be easily accomplished
at any time without removing the shoe, for the slots and holes through which the
teeth of the biting devices pass are outside the line of the nails.
The shoes may be widened and thickened to strengthen them where the slots
and mortices are to receive fastenings in connection with the biting devices.
There may also be added to the shoe, one, or more, set screws adapted to pass
downwards through the shoe and in virtue of the bearing of its, or their, noses upon
the ground, to more or less balance the shoe.

Improvements in Shoes for Horses and other Animals of Draught
or Burden.
I, GEORGE EDWARD PRITOHETT, of Oak Hall, Bishop's Stortford, in the
County of Hertford, Architect, do hereby declare the nature of this invention, and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
My invention relates to improvements in shoes for horses and other animals of
draught or burden, and its object is to make provision for the shoes automatically
acquiring a trustworthy grip of the ground from the moment the foot is put down,
without requiring any extra effort or attention on the part of the animal.

page_text: I slot or form sinks or mortices in the shoe, either in front or at either or both
the sides, and in these lots or their equivalents I more or less loosely pivot a
biting or gripping device consisting of a toothed plate or strip of metal or piece of
wire so shaped a to present one or more bearing surfaces or points of contact with
the ground.
In order that my invention and the means by which it is to be carried into
practical effect may be thoroughly understood, I will now describe it and them in
detail, referring in so doing to the accompanying drawings which are to be taken
as part of this Specification and read therewith.
Fig. 1 is a front elevation of the underside of the near shoe of a horse.
Fig. 2 is a sectional plan taken on the line A-B of Fig. 1.
Fig. 3 is a side elevation of Fig. 1 seen from the right hand side.
Fig. 4 is a transverse section taken on the line C-D of Fig. 1.
Fig.
5 is a sectional side elevation showing the pin or rivet in a slanting
position.
Fig. 6 is a front elevation of the upper side of the near shoe of a horse fitted
with a modified form of biting or gripping device.
Fig. 7 is a side elevation of the same.
Fig. 8 is another modified form of biting or gripping device.
Fig. 9 is a front elevation of the underside of a shoe fitted with a further modified
form of biting device.
Fig. 10 is a side elevation and partly in section of Fig. 9.
Fig. 11 is a side elevation and partly in section of another modified form of
biting or gripping dovice.
Fig. 12 is a front elevation of the underside of the shoe.
In the simple form of my invention shown in Figs. 1 2 and 3 the slot or mortice a
is cut through the front part of the shoe b. Into this slot or mortice the bitor or
gripper, several forms and modifications of which are shown in detail, is inserted
and pivoted by the split-pin or rivet d, which passes through a hole in the shoe
and biter, and is of sufficient size to allow the biter e to turn upon the pin or
rivet and so always assume a horizontal position or nearly so, no matter what the
position of the hoof or shoe may be. A similar groove or mortice a with biter or
grippere similarly arranged but eccentrically pivoted, is shown at the back part of
the shoe in Fig. 1. For the split pin or rivet da serew serving likewise as a
pivot may be substitute.
A different arrangement in which also the grippers or biters c are differently
shaped and differently attached is shown at Fig. & 7.
Referring to Figures 6 and 7. Instead of the slot or mortice a two holes or
perforations, are made near the periphery of the shoe, while a clip horn or
projection, formed in the upper side of the shoe, serves as a point of attachment
for the pivoting pin, screw or rivet d. In this variation of my invention it is
advantageous to impart any convenient curve to the legs h of the biter or
gripper c instead of being straight as shown or, if necessary, to the whole piece
forming the biter or gripper, so as to facilitate the insertion or removal of the
same from the wide.
I have found it practically advisable in order to relieve the pin, rivet or
screw from the necessity of bearing the whole weight which the biters or
grippers are compelled to sustain, to make the ends and the sides of the slots a
inclined instead of being vertical throughout as shewn at 6, 6 Figs. 2 and 12,
the inclined sides and ends being shewn in Figs. 1, 2, 3, 4 & 12. The biters
aud grippers as shown in Figs. 1, 2, 3, 4 & 3, whether the sides of the slots
elinel or vertiche conciled or havelled to prevent the
top of the biter pressing into the horn of the hoof, and the holo through which
the pivoting pin or rivet d passes is made sufficiently large to enable tho gripper
to freely oscillate, thereby allowing the upper surface of said biter to bear upon
the inclined ends of the slot or mortices a.

page_text: By pivoting the biter eccentrically as shown in Fig. 2, it may be caused to
take a better and firmer hold of the ground.
A further variation of the arrangement is represented in Figs. 9, 10 and 11.
In this case a special form is given to the biter or gripper, so that when the
weight of the horse or other animal comes upon it, it spreads out and assumes
the shape shown by the dotted lines in Fig. 10. These biters or grippers c may
be formed out of strips of metal or pieces of wire j formed in any convenient
shape. This gives a certain amount of spring to the biter and also enables a better
grip of the ground to be obtained and checks concussion to the hoof. When
these forms of biter are adopted, it is pivoted on one or more pins, rivets or
screws d, d, d as shewn in Figs. 9 and 10, or the biter or gripper c may be pivoted
on a central pin, rivet or screw k as shewn in Fig. 11.
In Fig. 5 the pin, rivet or screw d is shown in an inclined position, in order to.
prevent its being damaged or loosened should the front of the shoe 6 as frequently
happens become worn away.
It should in all cases be remembered that the biters may or may not be made of
the same curvature as the shoe, while the slots or mortices serving for the reception
of the biters or grippers need not be pierced completely through, but merely
thinned out to the required degree, thus preventing the top of the biter or gripper
pressing against the horn of the hoof; this is shown at 7, 7 Figs. 10 and 11.
I do not confine myself to the form of the biters or grippers as shewn, but
I may use any forms as may be found convenient without departing from my
invention.
Instead of thickening or caulking the inner side or other parts of the shoe I may
use a set screw i which can be adjusted to the required depth of the biters or
grippers placed around the said shoe, so as to form a more even pressure for the
whole underside surface of the shoe.
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:
1. The arrangements of biters or grippers in slots or mortices in a horse or
other shoe, in the manner described in order to enable a better grip of the ground
to be obtained.
2. The eccentric pivoting of the biter as shewn, for the better attainment of the
same end.
3. Imparting a curved or cranked shape to part or the whole of the gripper or
biter to facilitate its insertion or removal.
4. The bevelling of the slots or mortices to enable the weight or thrust of the
biter or gripper, to be partially borne by the metal of the shoe instead of wholly
by the pivot or pin.
Dated this 8th day of August 1892.
