PROVISIONAL SPECIFICATION.
Improvements in Horseshoes and Hoof Pads.
I, MICHAEL HALLANAN, of 190, West 4th Street, New York City, United
States of America,. Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to certain improvements in combined shoes and hoof pads
for horses, and bas for its object to provide a pad having an elastic boaring surface
located at the heel portion which shall be adapted for use with shoes of different
shapes and sizes. Another object of the invention is to provide a shoe adapted.
for ready adjustment to the boof of the horse; a third object of the invention is
to provide independently formed calks provided with means for ready_attachment
to the shoe; to provide a pad especially designed for horses suffering from
navicular and kindred diseases; and further to improve the pad and shoe in various
particulars, all as will be bereinafter fully set forth.
I will first describe my improved adjustable pad in connection with a shoe
having independently formed calks. The body of the pad is usually made of
leather, and is provided with a raised bearing block at the heel portion usually
formed of rubber and extending across the frog and usually secured to the body
of the pad by stitching. At its forward edge a ledge or shoulder is formed ou
the block adapted to take under the shouldered rear ends of the metal shoe
provided with the usual nail grooves, the shoulders being produced by reversely
rabbetting both the shoe and the block. The calks are formed independently of
the shoe and are provided with screw threaded shanks or stems adapted to be
screwed into interiorly threaded perforations formed in the shoe. By preference
the perforations will be located adjacent to the ends of the nail grooves so that
when the calks are screwed in as tightly as possible they may each be held against
turning by the head of a nail which is left to project slightly.
In a modified construction the raised heel block is provided with a forward
extension extending parallel to the metal shoe which is made in three sections, a
toe section having nail apertures at opposite ends and having its extremities
recessed on their upper faces next the body of the pad to receive the extremities
of the side sections which are correspondingly recessed at their forward ends and
provided with pail grooves extending along them. The overlapping ends of the
sections are pivoted together by means of pins or screws the heads of which are
preferably located at the back or top surface of the toe section and at their rear
ends the side sections are provided with shoulders engaging corresponding seata
formed on the forward edge of the block at the sides thereof. The opposed ends
of the shoe and pad are cut square off and the inner ends of the rabbets are also
square, that is they rise vertically and also range transversely at right angles to
the axis of the shoe. Also the most rearward nail hole is in advance of the
forward rabbetted ends of the block. With this:construction the heel portion of
the pad, including the block, is allowed to yield to a limited degree relatively to
the foot under the pressure of the latter and is not held rigidly against the heel,
but at the same time, by reason of the lap joint aud squared ends, there is not
permitted such a freedom of movement of the pad as would allow it to flap and
admit of the entrance of sand when the weather becomes wet. The formation of
5 the shoe in a series of three sectione, a toe section and side sections reuders the

page_text: shoo more readily adjustable to the hoof and the calks being removable may be
replaced when worn by simply driving in the nail and unscrewing the calks.
It will be understood, of course, that the rubber pads may be solid, that is
extend to the shoes and be of uniform thickness throughout, thereby leaving no
hollow. The pads prevent balling of snow, the picking up of nails or pebbles,
and afford an absolute safeguard against lameness. It will also be understood that
the shoes may be provided with integral calks.
The improved rubber pad specially designed for horses suffering from uavicular
and similar diseases, is formed hollow on its inner side whereby when the pad is
secured to the leather backing a pneumatic cushion is formed in the pad of a size
to extend at all sides of the navicular bone. This formation of the pad prevents
all shock to the said bone, the shock being received by the surrounding solid
parts of the pad, and in the case of navicular disease the pad thus will go far
toward effecting a cure, especially if the disease is in its incipiency. The shoe
employed in this case is provided with a groove for the nail heads at one side or at
least the inner wall of such groove is curved to correspond with a curved dovetail
groove at the toc, said groove being closed at its inner side and in it a toe calk is
secured by producing a dovetail rib on its inner side, the said toe calk after having
slid into its groove being held in place by a screw or like device. The pad is
preferably formed with projections at each side at the heel. The heel calks in this
shoe would be secured in the same manner as the toe calk.

Improvements in Horseshoes and Hoof Pads.
I MICHAEL HALLANAN, of 190 West 4th Street, New York City in the
County and State of New York, United States of America, Manufacturer 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.:-
This invention relates to certain improvements in combined shoes and hoof pads
for horses, and it has for its object to provide a pad having an elastic bearing
surface located at the heel portion which shall be adapted for use with shoes of
different shapes and sizes.
Another object of the invention is to provide a shoe adapted for ready
adjustment to the hoof of the horse; a third Bbject of the invention is to provide
independently formed calks provided with means for ready attachment to the
shoe; to provide a pad especially designed for horses suffering from navicular and
kindred diseases, and further to improve the pad and shoe in various particulars,
all as will be hereinafter fully set forth.
In the accompanying drawings which serve to illustrate my invention,
Figure 1 is a face view showing my improved adjustable pad in connection with
a shoe having independently formed calks;
Figure 2 is an edge view of the same, one end of the shoe being shown in
section to illustrate the means employed for attaching the calks;
Figure 3 is a view similar to Figure 1, showing a pad of a slightly modified form
in connection with an adjustable shoe ;
Figure 4 is an edge view of the same, similar to Figure 2.
Figure 5 is a central vertical longitudinal section taken through a shoe having
one of my improved pads of a form adapted' for horses suffering from navicular
and similar diseases.
:

page_text: Figure 7 is a face view thereof.
In Figures 1 to 4 of the drawings, A represents the body of the pad usually of
leather, and B represents the raised bearing block at the heel portion thereof,
usually formed of rubber and extending across the frog, being usually secured to
the body A by stitching 6 as indicated in Figure 1.
At its forward edge, a ledge or shoulder B is formed on the block B, adapted to
take under the shouldered rear ends c-of a metal shoe C provided with the usual
nail grooves c, the shoulders being produced by reversely rabbetting both the shoe..
and the block B.
The calks D are formed independently of the shoe C and are provided with
screw threaded shanks or stems d, adapted to be screwed into interiorly threaded
perforations formed in the shoe C at proper points as iudicated in Figure 1. By
preference the perforations will be located adjacent to the ends of the nail
grooves cl, so that when the calks are screwed in as tightly as possible they may
each be held against turning by the bead of a nail which is left to project.
slightly as indicated in Figure 2.
The construction shown in Figure 3, is very similar to that above described. In
this case, however, the block B is provided with a forward extension B², extending
parallel to the metal shoe E which is made in three sections, a toe section E,
having unil apertures e at opposite ends, and baving its extremities recessed on.
their upper faces next the body A of the pad to receive the extremities of the side
sections E, E³, which are correspondingly recessed at their forward ends and
provided with nail grooves el extending along them.
The overlapping ends of the sections E, E are pivoted together by means of
pius or screws e, the heads of which are preferably located at the back or top
surface of section E, and at their rear ends the side sections E, E³, are provided
with shoulders engaging corresponding seats formed on the forward edge of
block B at the sides thereof.
↑
The opposed ends of the shoe and pad are cut square off and the inner ends of.
the rabbets are also square, that is rise vertically and also range transversely at
right angles to the axis of the shoc. Also the most rearward nail hole is in
advance of the forward rabbeted ends of the block B. With this construction the
heel portion of the pad, including block B is allowed to yield to a limited degree
relatively to the foot under the pressure of the latter and is not held rigidly
against the heel, but at the same time, by reason of the lap joint and squared
ends, there is not permitted such a freedom of movement of the pad as would
allow it to flap or permit of the entrance of sand when the leather becomes wet.
The formation of the shoe in a series of three sections, a toc section and side
sections renders the shoe more readily adjustable to the hoof, and the calks D
being removable may be replaced when worn, by simply driving in the nails d' and
unscrewing the calks.
It will be understood, of course, that the rubber pads may be solid, that is,
extend to the shoes and be of uniform thickness throughout, thereby leaving Do
hollow. The pads prevent balling of snow, the picking up of nails or pebbles, and
afford an absolute safeguard against lameness. It will also be understood that the
shoes may be provided with integral calks if desired.
Referring to Figures 5, 6 and 7, the rubber pad F is formed hollow on its inner
side as shown at f, in Figure 5 and indicated by the same letter in Figure 7,
whereby when the pad is secured to the leather backing G, a pneumatic cushion is
formed in the pad of a size to extend at all sides of the navicular bone. This
formation of the pad prevents all shock to the said bone, the shock being received
by the surrounding solid parts of the pad, and in the case of navicular disease, the
pad will thus go far toward effecting cure especially if the disease is in its
incipiency.
In these figures I also have a shoe H having a groove for the nail heads, at
one side of the shoe, or at least the inner wall of such groove curved to correspond

page_text: with a curved dovetail groove h¹ at the toe, said groove being closed at its inner
sido as at and in the groove h a toe calk His secured by producing a dovetail
rib on its inner side, as clearly shown in Figure 5, the said toe calk, after
having slid into its groove h¹ being held in place by a screw h, or like device.
Preferably the pad is of increased thickness at points f,, to form projectious at
each side at the heel. The rabbetted meeting points of the shociand pad in these
figures are the same as described in reference to Figures 1 to.4..
The heel calks in this shoe would be secured in the same manner as the toe
calk H¹.
-
Having now particularly described and ascertained the naturo of my said inven-
tion, and in what manner the same is to be performed; I declare that what I
claim is;-
1. A horse shoe pad having an elastic block, the sides of which, at the heels
project laterally to the side edges of the pad, the said side extensions terminating
rearwardly of the nail holes and formed with squared rabbeted ends, substantially
as described.
2. A foot covering for horses, comprising the pad having a yielding block at the
heel provided with side extensions, and a shoe terminating at such side extensions,
the said extensions and the shoe having squared meeting ends that are each
rabbeted and lap each other, substantially as described.
3. A foot covering for horses, comprising a pad having at the beel a yielding
block formed with side extensions, and a shoe terminating at such side extensions,
the said extensions terminating forwardly at a point rearward of the rearmost nail
boles of the shoe, and the opposed ends of the shoe and extensions being rabbeted
and overlapping, substantially as described.
4. The herein described pad for borse shoes having the pneumatic cushion and
the solid parts, substantially as and for the purpose specified.
5. The horse shoe having the calks secured in the manner shown, substantially
as described.
