I, RICHARD BRADSHAW of Daisy Bank, Swinton, in the County of Lancaster,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object a horse shoe that shall be less slippery than iron or
steel.
I form the bottom surface mainly of lead, or of lead and wood alternately, or wood
only, but as the lead itself would soon wear off and come away, if unprotected, I form
the skeleton of the horse-shoe of a dove tail trough of iron or steel. This is rolled in
straight channel bars, is then bent to shape, and then the sides are pressed to the right
dove tail form in a press or otherwise. The lead is run in, and when freshly cast,
projects slightly above the iron edges. When in use, pieces of quartz, etcetera, get
embedded in the lead, greatly increasing its holding power. The holes are pierced
through the iron, and afterwards holes of slightly larger diameter are formed through
the lead and nails, preferably with heads, equal in length to the thickness of lead, are
driven in the usual manner. Occasionally divisions can be welded across the shoe, or
a shoe of malleable cast iron can be formed with these divisions. In this case the
divisions preferably carry the holes for the nails.
When ordinary nails are used, they are driven in by a punch resting with their
heads on the iron of the horse-shoe.
In place of lead, I may use wood, preferably with its fibre placed end wise to the
wearing surface. One good plan is to form the shoe with lead and wood alternately.
The wood is thoroughly dried, and forced into the iron trough end on so that the grain
shall be vertical, then the lead is run in. By making the wood of dovetail shape
laterally, the lead run in and the wood mutually support each other in the shoe and as
the wood expands again with moisture the whole is compacted together in the most
rigid manner.

page_text: Improvements in or Appertaining to Shoes for Horses or other
Animals.
I, RICHARD BRADSHAW, of Daisy Bank, Swinton, in the County of Lancaster,
Mechanical Engineer, 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 :-
The object of this invention is to provide a horse shoe that will render the animal
less liable to slip than those made wholly of iron or stool.
It consists essentially in forming a portion of the bottom or wearing surface of the
shoc of lead or other soft metal or metallic compound the lead being imbedded in
recesses or holes in the harder metal-iron or steel of which the base of the shoe is
made.
It will be readily understood by reference to the annexed drawings Fig. 1 being a
plan view of the bottom or wearing surface of the shoe and Fig. 2 a sectional elevation
on line xy.
The base A of the shoe is formed with a groove or channel preferably extending its
entire length as shown and this groove or channel is filled in with lead B ; or other
soft metal or metallic composition may be used instead.
The base A of the shoo may be formed either from wrought iron or steel and the
groove rolled or forged therein or it may be made of malleable cast iron which I prefer
for light work on account of its greater cheapness and the facility with which the
shoes can be manufactured.
Wrought iron or steel shoes may be forged from bars of proper cross section or may
be stamped out and the sides of the groove may be turned over or inclined to form a
dovetail groove.
When the hard metal part A of the shoo is formed the lead B is run into the groove
and completely filled providing an extended wearing surface of soft metal between the
edges a of hard metal. Care studs or other projecting pieces fitted to the shoe A
round which the lead flows and is thereby prevented coming out. Instead of studs
such as shown pieces may be cast in position or forged across according to the
material with which the shoe is made. In practice it may be found unnecessary to
provide any projecting pieces or studs to retain the lead as the continual concussion
will tend to keep it tightly wedged in the groove or hole. D, are the nail holes formed
in the soft metal by inserting pegs in the holes in the hard metal while the former
is being run in. When in use the edges a protect the lead and confine it in
position.
As already described I prefer to make the base of the shoe of malleable cast iron
and fill the groove with molten lead and allow the two to cool together before being
applied to the horses foot and then apply and fit the shoe while cold. Where it is
deemed necessary to heat the shoe to fit it to the horse's foot the shoe may be fitted
before being filled with lead and when cool nailed in position.

page_text: It will be obvious that although one groove is mentioned two or more grooves may
be used passing partly or wholly round the shoe or a series of holes may be
formed to receive the lead but I at present prefer the single groove shown.
Having now particularly described and ascertained the nature 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 having a base of hard metal and a wearing surface in part formed
of lead (or other soft metal or metallic composition) run into or carried in
the base of the shoe for the purpose of preventing slipping substantially as
described.
2. In a horse shoe the combination with a groove or channel to receive molten lead
or the like of studs or projections to retain thelead in position substantially as described.
