our executors, administrators, and assigns, or such others as we, the
said Richard Winder and Henry Pritchett, our executors, administrators,
and assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed,
5 should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN HORSE-SHOES,'
upon the condition (amongst others) that we, tho said Richard Winder
and Henry Pritchett, our executors or administrators, by an instrument
0 in writing under our, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention,
∙and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters
5 Patent.
NOW KNOW YE, that I, the said Richard Winder, on behalf of myself
and the said Henry Pritchett, do hereby declare the nature of the said
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 (that is to say) :-
Our Invention consists in the form of that part of the shoe that is
nailed to the horse's foot; also in placing india-rubber or other clastic
material in this shoe, and in the use and form of the steel or iron plate
that goes upon the ground, and incloses and protects the india-rubber
or other elastic material from the road, and which acts as a spring to
resist the jar and consequent injury to horses' legs that travel upon
hard roads.
To enable the horse to travel over ice or other slippery material we
sometimes take off the lower steel or iron plate and so let the india-
rubber come upon the ice.
Sometimes we make the steel or iron plato that goes on the ground
in several parts, and so leave spaces for the india-rubber to come upon
the ground when the weight of the horse is on the shoc, and so provent
dinning

page_text: these holes on to the ground with the horse's weight to prevent
slipping.
We sometimes attach the india-rubber to the iron by cement alone,
sometimes with cement and other fastenings, such as clips, lugs, or
other arrangements, which are made to allow full elasticity to the india- 5
rubber or other elastic material used; and sometimes we make the shoes
and enclose the india-rubber or other springs in place by lugs, rivets,
and clips alone without cement.
The accompanying Drawings show more fully the manner in which
we carry our Invention into effect.
Figs. 1, 2, 3, 4, Sheet 1, show four plans of horse-shoes under this
Patent, as well as the details of four modes of fixing the upper and
lower parts of the shoe together, and allowing still more elasticity to the
india-rubber between them, as described below by reference letters.
1
In Fig. 1, A is a plan, showing the under side of the part of the shoo 1
that is nailed on to the hoof; B is the hollow channel in the shoe, in
which the india-rubber is placed on the tops of the nail heads after the
part A has been securely fixed to the hoof; O is the india-rubber, partly
shown in section, that the shape may be the better understood; D are
the nail holes at the bottom of the channel B; E is the plate that goes 2
on the ground and takes the whole wear; F is the lug on the inside of
the toe end of the plate E. It is made with an elongated holc to allow
elasticity at the front part of the shoc at each step of the horse. The
plate E is held in position by a round pin G passing through the lug F
through each rib K and rivetted on the outside at A; G, the pin just 2
mentioned above; H shows one of two lugs at the heels of the plate E
to allow elasticity at each step of the horse, and yet secure the two parts
of the shoe A and E together; I, a recess moulded in the india-rubber
to allow space for the projecting nail heads.
In Fig. 2 the plan is shewn where dovetailed keys are used to secure
the parts of the shoe A and E together, and yet allow elasticity at each
tread of the horse.
The plan is more fully described as follows:-A shows the under side
of the part of the shoe that is nailed to the hoof; B, the recessed part
of the shoe, in which the nail holes arc punched; B', three thicker flat
parts of the shoc, one at the toc, and one at each hoel; these hold the

page_text: dovetailed keys; they have also a hole in the centre of each, in which
the pins on the plate E work; O, the india-rubber, partly in section, to
show more clearly the different thicknesses that are necessary to fit the
shoe A, and take an even bearing on the plate E; D, the nail holes,
the same as in ordinary shoes, except more in quantity, so as to have
fresh holes for nailing at each romove; this applies to each design.
E, the plate that goes on the ground; F, the front pin on the plate E,
which has a part hollowed out, more clearly seen at H. After this pin
is fixed in position the dovetailed key G is driven in and secured by
> spreading open the narrow end. The amount of elasticity is then equal
to the part hollowed out working against the side of the key. The
plate E is then secured from falling off. G, three dovetailed keys to
hold A and E together, and yet allow full and free elasticity for the
whole thickness of the india-rubber; H shows one of two pins at each
5 heel of the plate E; I, recess moulded in the india-rubber to allow space
for the projecting nail heads, and to keep the india-rubber in position as
well.
Fig. 3 shews another mode of securing the parts A and E together
at the same time allowing proper elasticity. A, the under side of the
O part of the shoe that is nailed to the hoof; B shews a section of A on
the line c, d; C shews the form the india-rubber has to be moulded for
this particular plan; D, the nail holes at the bottom of the channel, as
in Fig. 1; E shews the plate that goes on the ground (in section);
F shews one of three lugs to hold A and E together, and yet allow
5 elasticity, see section on line a, b; G, the wire that passes around on the
inside of A, and secures A and E together, as described at F. The wire
is held in position by burring up the two ends at the heels.
in india-rubber over the nail heads, see section on line c, d.
I, recess
Fig. 4 shews another method of securing the parts A and E together,
O proper allowance being made for elasticity. A, the under side of the
part nailed to the hoof; B, the hollow channel to hold the india-rubber.
The section on the line c, d, is shewn in the side view. C, the india-
rubber; D, the nail holes; E, the plate that goes on the ground; F, the
front lug, two views shewn of it, a plan also of the recess in which it
5 works is shewn at A; G, the pin that holds the plate E in position and
allows free action to the india-rubber; H, shews one of two lugs at the
heel of the shoe. The mode of fixing these in position is shewn at the
heel of A at K; L shews the end view of K before the plate N is fixed

page_text: by cement.
Fifthly. Roughening the plates that go upon the ground to prevent 20
horses slipping in frosty weather, or while travelling upon any slippery
roads.
In witness whereof, I, the said Richard Winder, on behalf of
myself and the said Henry Pritchett, have hereunto set my
hand and scal, this Seventeenth day of September, in the year 25
of our Lord One thousand eight hundred and seventy-five.
