IMPROVEMENTS IN BOOTS AND SHOES
Year: 1885

page_text: I GEORGE ALBERT SWEETSER, of 35, Kennington Park Road, in the county
of Surrey, Engineer, do hereby declare the nature of my said invention for
IMPROVEMENTS IN BOOTS AND SHOES to be as follows:-
"
"
My improvements in boots and shoes consist in pressing into or mixing with the
soles or other parts subjected to the greatest amount of wear, a suitable hard
substance such as corundum or emery quartz, or the like.
The said substance is used either in lumps or in cakes mixed with any suitable
cement, so as to wear with the leather, rubber, composition or other material of
which the soles are made, thereby greatly increasing their durability.
I use the corundum or emery or other hard substance with or without cement,
inner sole, plate, punching vulcanizing or other means to hold it in its place.

I GEORGE ALBERT SWEETSER of 35 Kennington Park Road, in the county of
Surrey, 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:-
My improvements in boots and shoes consist in pressing into the soles and heels
of boots or shoes a suitable hard substance such as corundum or emery, quartz or
the like

page_text: The said substance is used in lumps so as to form a body with, and which will
wear with the leather, rubber, composition or other material of which the soles and
heels, are made, thereby greatly increasing their durability.
In practice I have found that in treating the soles or heels of boots or shoes it
is advantageous to press the pieces of corundum, emery, quartz or the like into the
material of the sole or heel from the inner surface the pieces of hard material
being kept in the sole or heel by the inner or middle sole, or by the use of a
suitable cement.
For pressing the emery, corundum or quartz into the material of the sole or heel
of a boot or shoe, I employ a mould or die such as that shewn in the drawing in
which figure 1 represents a plan and figure 2 a section of a mould with the matrix
or plunger suitable for treating a boot or shoe sole; figure 3 is a plan of the mould
shewing the lumps of corundum or other material placed therein; figure 4 is a
section of a boot or shoe sole treated according to my invention.
a, is the mould provided with a number of pins or studs b; and c, is the matrix
or plunger provided with holes d, corresponding with the said pins b.
The pieces of emery, corundum or quartz e, e, are placed in the mould a, as
shewn in figure 3, and the sole f, is placed therein with its inner surface downwards
and the matrix or plunger being forced down by suitable pressure the sole will be
forced onto the pieces of emery, corundum or quartz which will thereby be
imbedded in the inner surface of the sole as shewn in the sectional view at
figure 4.
It will be seen by reference to figure 4, that the pieces of emery,
corundum or quartz are not large enough to pass through the thickness of the sole
so as to leave the outer surface of the sole with a polished or smooth face. The
holes formed by the pins or studs b, are for the usual rivets or screws by which the
sole is attached to the other part of the boot or shoe.
a
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. A boot or shoe provided with a sole and heel (or either) formed of leather or
other suitable material into which lumps or pieces of corundum or emery, quartz
or the like have been pressed substantially as hereinbefore describod.
2. The manufacture and use of the improved soles and heels for boots and shoes
such soles and heels being formed by pressing lumps or pieces of corundum or
emery quartz or the like into the leather or other material of which the soles and
heels are made substantially as and for the purposes herein before described and
illustrated in the accompanying drawing.
