LIFT PLATE FOR RUBBER HORSESHOES

Application September 24, 1937, Serial No. 165,578
2 Claims. (Cl. 168-12)
The object of the invention is to provide a de
ments by providing for a quickly applied anti-skid
vice for use in conjunction with rubber covered or anti-slipping feature.
This anti-skid feature ,

With this object in view, the invention consists
in a construction and combination of parts of
which a preferred embodiment is illustrated in
the accompanying drawing but to which the in
vention is not to be restricted. Practical appli
cation may dictate certain changes or alterations
and the right is claimed to make any which fall
within the spirit of the invention.
In the drawing:
Figure 1 is a bottom plan View of the conven
tional rubber shoe showing the invention applied
in operative position.
Figure 2 is an edge elevational View of the struc
ture of Figure 1.
Figure 3 is a sectional view on the plane indi
cesses ! I, so that when the nails are used without
the lift plate, the lugs are held clear of the ground.
When the lift plate is employed, however, its
thickness is sui?cient to cause the lug heads 13
to project to the plane of the undersurface of
the shoe, or so close to the plane of the undersur
face that normal compression of the rubber un
der the animal's weight will bring the lug heads
into contact with the surface.
The ear l5 acts as a lateral bearing member for
the lift plate and when in contact with the inner
wall of the recess II will position the nail holes
l6 in the lift plate directly over the nail holes in
the shoe.

when the rubber is compressed, its lower edge will
be exposed to the surface to engage the same.
In a conventional rubber covered horseshoe,
such as illustrated at if], a metal core is entirely
claimed as new and useful is:
enclosed with a rubber covering which, however,
is reduced in thickness at opposite sides of the
shoe, as indicated at H, where the nails are ap—
plied to attach the shoe to the hoof, the lateral
recesses thus provided in the shoe serving as
clearance spaces for the nail heads.
In bad weather, however, the noise reducing
feature of the rubber shoe is of no value and
the rubber covering itself can be of little use in
preventing sliding on iced or sleety pavements, so
that the practice is to remove the rubber shoe
and replace it with a metal one, having the nec
essary non-skid feature. This practice, however
entails constant preparation for shoe changing
with the attendant expense of maintaining a
blacksmith constantly available to make the shoe
changes when necessary.
The present invention, however, contemplates
the use of the rubber shoe on sleety and icy pave
The invention having been described, what is
1. In combination with a horseshoe having a
rubber covering and recesses at the edge to pro
vide clearance spaces for the attaching nail heads, 3
a lift plate seated in a recess, and nails passing
through the plate and through the shoe and hav—
ing lug heads whose lower edges are approxi
mately in the plane of the undersurface of the
40
shoe.
2. In combination with a horseshoe having a
rubber covering and recesses at the edge to pro
vide clearance spaces for the attaching nail
heads, a lift plate seated in a recess and provided
with a lateral ear engaging the side wall of the
recess, and nails passing through the plate and
through the shoe and having lug heads Whose
lower edges are approximately in the plane of the
undersurface of the shoe.
