PROVISIONAL SPECIFICATION.
Improvements in Horse Shoes.
We THOMAS BOLAS of S Grove Terrace, Chiswick, Analytical Chemist & LENA
WARDLE, of 9 Charlotte Street Bedford Square London do hereby declare the nature
of this invention to be as follows:-
Our invention consists in the introduction of certain hard studs or pins into the
substance of a soft iron horse shoe, so that as the shoe wears it shall constantly
present an irregular surface to the road.
The hard pins or studs must be constructed of some metal or alloy which-unlike
the ordinary qualities of steel-is not made soft by the heating to low redness and
rather slow cooling, which takes place in the usual process of shoeing a horse. An
alloy well suited for the purpose is an alloy of steel and tungsten, an alloy of this
kind being sometimes commercially known as Mushet's special steel or tungsten steel,
and although we prefer to use pins made of an alloy of steel and tungsten, we may
use other hard metals or alloys, which do not soften by slow cooling.
To carry out our invention we may drill a number of holes through the shoe from
face to back or through the bar of iron from which the shoe is to be fashioned, and in
each of these holes we drive a pin or stud of the hard metal or alloy. We prefer to
leave the holes a little contracted on the top face of the shoe, or on that face of the
bar which is to form the top face of the shoe, and to drive in the pins from the lower
face.
Sometimes we set the studs or pins of bard metal in a mould, and then pour in a
quality of iron or steel which will be soft when cold.
Sometimes instead of drilling holes for the reception of the pins or studs of hard
metal we make the shoe or the bar from which the shoe is to be constructed red hot,
& then drive the studs or pins of hard metal into the plastic metal.
We claim the above described method of constructing a composite horse shoe of
hard & soft metal substantially as described.

Improvements in Horse Shoes.
We THOMAS BOLAS, 8 Grove Terrace Chiswick Experimentalist and LENA
WARDLE, 9 Charlotte Street Bedford Square London 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:-
Our invention consists in imbedding certain hard pins or studs in the softer body
of the shoe, so that as the shoe wears it shall constantly present an irregular surface
to the road. The hard pins or studs must consist of a metal or alloy which-unlike
ordinary steel is not made soft by the heating to low redness and rather slow
cooling which takes place in the usual process of shoeing a horse. Special non-
softening steels containing tungsten may be used for the pins or studs; the alloy
which we generally prefer to use being sold by Samuel Osborn Co. of Clyde Works
Sheffield, under the name of "R. Mushet's special steel." In some cases we, use studs
or pins of tungsten in the simple condition.
We drill or punch holes cavities or grooves through or almost through the shoes
from front to back, or we similarly treat the bars of iron from which the shoes are to
be fashioned; and in these cavities we drive pins or studs of the hard metal or alloy.

page_text: We generally prefer to leave the cavities a little contracted towards the top face of
the shoe, or towards that face of the bar which is to form the top face of the shoe.
We then drive the pins or studs in the cavities from the lower face. Sometimes we
fix the studs or pins in position by the process of hard soldering or brazing.
When the shoes are to be of cast metal we set the studs or pins in the mould and
then pour in iron or steel of a quality which will be soft when cold.
Instead of drilling or punching holes for the reception of the hard studs or pins, we
in some cases, make the shoe of the bar from which the shoe is to be fashioned, red
hot and then drive the pins or studs into the plastic material.
The pins or studs may be round, triangular or otherwise formed in section; and by
the term "stud" we intend to signify a more nodular & irregularly formed piece of
metal than would ordinarily be called a pin.
We claim the above described method of constructing a horse shoe compounded of
hard studs or pins not capable of being softened by slow cooling, and set in a body of
softer metal, substantially as described.
