Foregate York Currier do hereby declare the nature of this invention to be as
follows:-
Our invention consists of a Boot sole made of canvas cloth, saturated with an
impervious composition, or varnish, mixed with a portion of sand, and which we
propose to call a concrete Boot sole. The sole is placed on the top of an ordinary
leather sole, covering the whole of the bottom, or in such sized pieces, as may be
needful to place, on the worn out parts, to regulate the tread.

page_text: We, HENRY GEORGE BOSTON, Manufacturing Chemist, Piccadilly, York, and
ROBERT COMBE, Currier, of Foregate York, 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 saturating cloth, linen, or any other suitable flexible
material with a solution of tar, afterwards applying to such material the composition
as hereinafter set forth, and finally dredging sand upon the said composition; whereby
we produce a durable and cheap sole for boots and shoes.
The composition is as follows:-16 Parts of Black Pitch, 1 Part of Plaster of Paris,
2 Parts of Gutta Percha, 2 Parts of Rosin, 1 Part of India Rubber, or 1 Part (as
preferable) of dried Saw Dust, 2 Parts of Litharge, 8 Parts of Raw Linseed Oil and
8 Parts of Sand, preferably Calais.
The following is the method of compounding or of making the said composition.
The rosin after having been reduced to a fine powder is mixed with the Litharge
and Saw Dust. The other ingredients having been previously melted in an iron pan
or other suitable vessel, the powdered substances (Rosin, Saw Dust and Litharge) are
gradually added and stirred in until the whole is thoroughly well mixed.
After the material (for the foundation) has been saturated with the solution of tar,
the composition while hot or heated is applied thereto.
After which the said composition is pressed into the material by passing the same
between iron rollers, heated sufficiently to keep the composition in a molten state,
after which we finally dredge sand over the composition.
The improved sole is placed on the top of an ordinary leather sole, covering the
whole of the same, or in such sized pieces as it may be needful to place on the worn
out parts to regulate the tread.
For the soles of boots and shoes this improved material possesses greater durability
tban leather, and effectually keeps the feet dry and wears much longer. The material
does not become "spongy" like ordinary leather in "slushy" weather but is absolutely
weather proof.
Having now particularly described and ascertained the nature of this Inven-
tion and in what manner the same is to be performed, we would have it understood
that we do not confine or limit ourselves to any particular material for the foundation
but we declare that what we do claim is:-
1. The new or improved material substantially as and for the purpose shown and
described.
2. The composition as herein setforth for applying to cloth, and other suitable
flexible materials substantially as and for the purpose shown and described.
Dated this 20th day of November 1000.
