Improvements in Horse Shoes.
We, CHARLES VER TREESE POLLOCK, of No. 658, West 17th Street, in the City
of Des Moines, in the County of Polk, and State of Iowa, and JOHN W. MONARCH, of
No. 847, Third Street, in the City of Des Moines, in the County of Polk, and State of
Iowa, United States of America, Manufacturers, 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 new and useful improvements in that class of
horse-shoes which are provided with a yielding tread having for its objects to provide
a shoe of this character, which is simple and cheap and one which will effectively
relieve the joints of a horse from the shocks and jars consequent upon its feet
striking a hard pavement, and prevent slipping upon a smooth or wet and icy pave-
ment or when the horse is brought to a sudden stop. With these objects in view,
the invention consists in the novel features of construction and arrangement of the
parts hereinafter more particularly referred to.
In the accompanying drawings forming a part of this specification and in which
like letters of reference indicate corresponding parts,
Fig. 1 is a perspective view of the invention.
Fig. 2 is a transverse sectional view on the line x-x of Fig. 1.
Fig. 3 is a detail sectional view of one end of the horse-shoe illustrating more
particularly the adjustable securing and tightening devices for the yielding tread.
Fig. 4 is a detail perspective view of the opposite ends of a modified form of the
invention, the intermediate portion of the shoe being broken away.
Fig. 5 is a similar view of another modification, and
Figs. 6, 7, 8, 9 and 10 are detail cross sectional views of modified forms of
the tread.
Heretofore in this class of inventions, it has been proposed to provide a horse-shoe
having a solid metal base with a yielding rubber tread which is either vulcanized
directly to the base or otherwise secured permanently thereto, but such shoes are
objectionable for the reason that when the tread becomes worn or injured, the
whole shoe must be removed and thrown away. In addition to this, horse-shoes
provided with yielding treads wear away much more rapidly than those formed
wholly of metal and when the construction of a shoe of this kind makes it
necessary to remove the shoe, whenever the tread becomes worn, and to replace it
with a new shoe, the hoof of a horse soon becomes ruined by the numerous holes
formed by frequent shoeing. Such shoeing, too, is expensive and the employment of
shoes such as referred to is attended with considerable expense, and they are
objectionable on this account.
It is the purpose of the present invention to overcome all of these disadvantages,
and to this end is provided a shoe having a solid base adapted to be attached directly
to a hoof, and a yielding tread supported upon the base by means of adjustable
securing devices which permit the ready removal of the tread from the base without
necessitating the removal of the base itself from the hoof, and which securing devices
likewise permit the equally expeditious attachment and tightening of the tread to the
base when the base is attached to a hoof..

page_text: Referring more particularly to the drawings, A designates the shoe which may be
of any required shape and size, comprising a base 1 of suitable metal having at
its inner edge a downwardly projecting flange 2, the outer face 3 of which is beveled
or inclined inwardly and upwardly, forming a channel or recess 4. At its opposite
ends the hase 1 is provided with projecting lugs or bearings 5, one
which is preferably provided with a conical opening 5* which extends through the lug
from the rear face thereof to its inner face.
or both of
Within the channel 4, bearing upon the base 1 and the outer face of the flange 2
and projecting beyond the edge of said flange is a yielding tread B formed of any
suitable material such as rubber, fibre, etc. or of a combination of such materials with
metal or canvas, and this tread may be of any desired thickness and of any desired
contour in cross-section. Connected to this tread are suitable means for securing it
within the channel 4. As shown in Figs. 1 to 3, this means consists of a non-
extensible flexible metallic rod or wire 6 extending longitudinally through the tread
near its base and having its ends screw-threaded and projecting beyond the ends of
the tread. These threaded ends are adapted to extend into the contracted ends of
the openings 5ª to receive conical securing and tightening nuts 7, which likewise
extend into the openings and bear upon the conical sides thereof.
By forming these openings conical as indicated and adapting the securing nuts
to extend practically through them it will be seen that the threaded ends of the
rod 6 may be comparatively short, as it is only necessary to extend them a short
distance into the openings 5ª in order to be engaged by the nuts.
It will be noted, too, that the securing nuts may thus be afforded an extensive
threaded bearing surface upon the ends of the rod 6 and that the nut by being
practically wholly countersunk in the lug 5 is protected against injury or from
accidental loosening by coming into contact with a stone or other hard object.
Upon tightening the securing nuts.7 upon the ends of the rod 6, the tread is
drawn into the channel 4 to closely conform to the outer face of flange 2 and during
such tightening by virtue of the inclination of such face, the tendency of the rod
is to force the tread upwardly into the channel and into firm contact with the base i
thereby providing a solid bearing not only for the inner face of the tread but for
its base also.
It very often happens in use that the tread is stretched or worn causing it to
become loose upon the solid portion of the shoe and when this occurs the looseness
may be readily taken up by tightening the securing nuts 7, thereby drawing the
tread into closer contact with the base and flange of the shoe.
In practice, while it is preferable to vulcanize the flexible securing rod within the
yielding tread, it may be detachable therefrom to permit its use with a new tread,
making it only necessary to throw away the worn out tread.
As herein before stated, the yielding tread B may be formed of a combination
of flexible rubber or fibre and metal and in Fig. 6 is illustrated one form of tread
constructed in this manner, which consists of a series of yielding sections 10
between the adjacent ends of which are interposed metallic leather or wood
washers 12, which may or may not be vulcanized to the yielding sections and may
be of the same diameter and contour as the tread to lie flush with the outer surface
thereof, or of less diameter than the tread to permit greater yielding but prevent
undue wear.
The washers 12 shown in the modified form of the invention indicated in Fig. 7
are provided with projecting points 12" which extend beyond the outer face of the
tread and serve as calks, this construction being very desirable when pavements are
covered with ice or snow.
In Fig. 8, the tread is provided with longitudinal strips of wire gauze 13 which
are embedded and vulcanized in it and in Fig. 9, the tread is vulcanized to a
non-extensible canvas strip 14 and is provided with a series of embedded wires 15
vulcanized within the same.
Instead of the parallel wires shown in Fig. 9, a coil of spring wire 15ª may be
embedded or vulcanized within the tread. to extend longitudinally through it as

page_text: shown in Fig. 10, which spring in addition to serving to prevent tearing or wear of
the yielding tread, also serves to maintain its shape."
In the modified form of the invention illustrated in Fig. 4, one end of the rod 6 is
secured in the manner herein before described but at its opposite end the rod is
provided with a head 16 adapted to fit into an enlargement 17 of an opening 18
through the lug 5. Intersecting this opening 18 is a slot 19 extending to the side
of the lug through which the end of the rod is inserted laterally into the opening 18.
After this, the head 16 is drawn into the enlargement 17 by the nut at the opposite
end of the rod and the lateral disengagement of the rod with the opening 18 is
thereby prevented.
In the modified form of the invention shown in Fig. 5, the rod 6 is dispensed with
and the tread B is vulcanized or otherwise permanently connected to a thin flexible
metallic strip 20 provided at its ends with thickened turned up portions 21 having
threaded projections 22 which receive securing nuts 23. These nuts instead of
being conical are formed with internally threaded nipples 24 which extend wholly
through and turn freely in openings in the lugs 5.
Froin the above, it will be apparent that a horse-shoe having a yielding tread is
provided, which is not only simple and effective, but one in which a worn tread may
be quickly and easily replaced by a new one by an unskilled person without removing
the main body of the shoe from a hoof, thereby saving the expense of shoeing and
making it only necessary to throw away the worn tread of the shoe without the
securing devices.
