Year: 1881

page_text: LETTERS PATENT to John Porritt Rothwell, of Lytham, in the County of
Lancaster, Vetenary Surgeon, for an Invention of "IMPROVEMENTS IN
AND ATTACHMENTS TO SHOES FOR HORSES AND OTHER ANIMALS."
PROVISIONAL SPECIFICATION left by the said John Porritt Rothwell at
the Office of the Commissioners of Patents on the 7th April 1881.
JOHN PORRITT ROTHWELL, of Lytham, in the County of Lancaster, Vetenary
Surgeon. "IMPROVEMENTS IN AND ATTACHMENTS TO SHOES FOR HORSES AND
OTHER ANIMALS."
My Invention relates in the first place to improved means for fixing and attaching
to shoes for horses and other animals raised or elevation pieces in such a manner
that they can be readily and securley fixed thereto. To this end I form slots
on the interior rim of such shoes at the heel and toe thereof, and I fit loosely
therein the bottom or under part of the said raised or elevation pieces, the top
part thereof overlaping the width of the shoe. The said slots are made preferably
of an angular or vee shape form, but any other suitable form may be given to
them, the object being to dovetail the raised or elevation pieces into the body of
the shoe. I may employ one or more screws to hold the under part of the elevation
pieces against the shoe in a lateral direction, and which bears against but does not
screw into the side of slot in the shoe. The sides of the raised or elevation pieces
which are thus dovetailed into the body of the shoe is comparatively narrow, and
may be made equal to the width of the slot, the novel part of this part of my
Invention being the formation of slots on the interior or exterior rim of the shoe,
and dovetailing therein the raised or elevation pieces for the purpose of preventing
the animal slipping. By these means the jar or concussion of such combined
appliances with the shoe is lessened. The points of the said raised or elevation
pieces may be flat or pointed as required. The Invention relates in the next place
to improvements in the means employed for connecting the shoes with the feet or
hoofs.
In lieu of nailing the shoes thereto as now practised, I form the shoe with or
connect thereto two or more straps which clasp around the body of the shoe, and
are secured thereto by means of countersunk screws which pass into the body of
the shoe in a horizontal direction.

the said John Porritt Rothwell in the Great Seal Patent Office on the
21st September 1881.
JOHN PORRITT ROTHWELL, of Lytham, in the County of Lancaster, Veterinary
Surgeon. "IMPROVEMENTS IN AND ATTACHMENTS TO SHOES FOR HORSES AND
OTHER ANIMALS."
My Invention relates in the first place to improved means for fixing and attaching
to shoes for horses and other animals raised or elevation pieces to prevent the
animals slipping, and to assist them in drawing heavy loads. To this end I form
suitably shaped slots on the interior rim of such shoes at the heel and toe part, and
fit into such slots the said raised or elevation pieces, the part fitting into the slots
being made narrow, and the lower part overlaping the surface of the shoe to any
required extent. The said slots are preferably made of an angular or vee shape
at each end thereof, but may be formed of any other suitable shape, the object
being to dovetail the upper part of such raised or elevation pieces into the body of
the shoe. One or more screws may be employed to hold the said elevation pieces
in position, such screws bearing upon the said pieces and shoe in a lateral direction.
The points of the said elevation pieces may be flat or pointed, as may be required.
The Invention relates in the second place to improvements in the manner and
means for connecting the shoes with the feet or hoofs. In lieu of nailing the
shoes to the feet or hoofs I form the shoe with or connect to the shoe two or more
suitably shaped straps which fasten themselves onto the wall of the hoof and pass
through the hoof and shoe, and are secured in position by means of nuts. The
surface of the shoe being suitably recessed to receive the nut which is screwed on
the end of the said strap which consolidates the shoe with the hoof.
And in order that the said Invention may be more fully understood, I have
caused to be appended hereto a Sheet of Drawings marked with letters of reference,
to which I will now refer. Fig. 1 is a cross section, and Fig. 2 a plan of a hoof
with part of my Invention applied thereto. The shoe in this case is made in two
parts a, b, which fit face to face, the part 6 being combined with the part a by
means of the screws e. On the inner rim or edge of the part a suitably shaped
slots or recesses c are made, into which the projections on the part b fit. The said
shoe may have formed thereon any required number of slots, but in practice I have
found three to be sufficient, indentations g and openings h being made in the
horny substance of the hoof and on through the wall thereof; one or more metal
straps are inserted into the indentations g, and through the openings h near the
rim of the hoof. The free end of each strap f is formed with screw threads to
receive a nut i, which nut is screwed thereon and fits into a recess formed on the
surface of the shoe, and thereby consolidates the shoe to the foot. The part b is
cast or formed with projections j corresponding in size and number to the recesses c,
into which they fit, and the two parts are fixed face to face by screws e, which may
penetrate a short distance into the side of the slotted recess c as indicated, whereby
the two parts a and b are firmly combined together, and the connection of the
shoe to the foot by the straps f secured. By these means a more durable connection
or fastening of the shoe with the foot is obtained, and the evils arising through
pricking of the animal's feet remedied. Figs. 3, 4, 5, and 6 indicate separate views
of the two parts a and b before they are combined together, as shown in Fig. 1;
Figs. 7 and 8 represents a cross section and plan of a shoe m cast in one piece with
recesses and openings to receive the end of straps f and nuts i. Slots are formed
on the interior rim of the shoe m to receive the narrow part of raised or elevation
pieces n, which are employed to prevent the animal slipping, or to assist the
animal in drawing heavy burdens. The said raised or elevation pieces n when in

page_text: position overlap the surface of the shoe at the part where the recesses are made,
and form the bearing or wearing surface. The said elevation pieces are thus dove-
tailed into the shoe, and are securely held in position by the screws k which pass
through the narrow part thereof and penetrate a short distance into the shoe.
When not required for use the said elevation pieces n can be readily removed by
and nut i
removing the screws k; Fig. 9 represents a front view of the strap
employed to fasten the shoe onto the foot. The portion of the strap f which is in
contact with the wall of the hoof may be made flat as shown, and the other end
rounded to receive the nut, but I do not bind myself to any particular shape of
strap; Figs. 10, 11, and 12 represent a side view, front view, and plan respectively
of the hereinbefore described raised or elevation parts n; Fig. 13 represents a
modification in the form of strap and manner of connecting the shoe with the foot.
In this case a single opening is made in the hoof to receive the strap, which is
formed of an angular form at its upper part, which part grips the front edge of the
said opening, and lays flat on the outer wall of the hoof. An important part of
my Invention consists in dispensing with the use of nails for fastening the shoe onto
the foot, and employing in lieu thereof the indicated or other suitable form of strap,
as various forms may be employed without departing from the principal of my
Invention. A variation is shown by Fig. 13.
Having now described and indicated the nature and intent of my Invention,
and some methods for carrying the same into practical effect, I would have it to be
distinctly understood that what I claim as secured to me by the hereinbefore in part
recited Letters Patent is,-
First. The use and employment of straps of the indicated or other suitable
shape for fixing and consolidating the shoe with the foot for the purpose
specified.
Secondly. The manner and means employed for connecting the said straps with
the wall of the hoof and the shoe, substantially as set forth and illustrated in the
Drawings.
Thirdly. Forming the said shoes with slots or spaces on the inner rim to receive
raised or elevation pieces for the purpose specified.
Fourthly. The form of the said elevation pieces and the manner of fastening
the same to the shoe.
Fifthly. Forming the shoe in two parts, and combining the same together by
means of angular recesses and projections, and consolidating the same to the foot
of the animal by means of straps formed at one end to receive a nut.
In witness whereof, I, the said John Porritt Rothwell, have hereunto set
my hand and seal, this Seventeenth day of August, in the year of our
Lord One thousand eight hundred and eighty-one.
