IMPROVEMENTS IN INDIA RUBBER SOLES FOR BOOTS AND SHOES
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I RALPH SLAZENGER Moss of 56 Cannon Street in the City of London,
Merchant do hereby declare the nature of my Invention for IMPROVEMENTS
IN INDIA RUBBER SOLES FOR BOOTS AND SHOES to be as follows:-
In attaching India rubber soles to boots and shoes for use in playing at Lawn
Tenuis, and for other purposes, it has been the custom hitherto to cement a piece
of leather or rubber between the sole and the heel part of the shoe to form the
heel.
Now the object of my invention is to make the sole and heel-piece all in
one; and thereby effect a great saving in labour and cost and also prevent a great
waste of material and add to the durability of the sole.
I form my improved entire soles by casting them in one piece which entirely
obviates the necessity of cementing or attaching an additional piece of rubber or
other material which has hitherto been necessary thereby effecting a considerable
saving of labour and obtaining perfect solidity and firmness of attachment which
has hitherto not been achieved in rubber soles intended to be attached to boots and
shoes with leather or other insoles.
In some cases I also add to the sole a toe piece similarly forward to that of the
heel whereby greater durability is obtained'; the toe part being that part of the
sole which is most subject to wear.

Merchant, do hereby declare the nature of my said Invention for "IMPROVEMENTS
IN INDIA RUBBER SOLES FOR BOOTS AND SHOES" and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
In attaching india rubber soles to boots and shoes for use in playing at
Lawn Tennis, and for other purposes, it has been the custom hitherto to cement a
piece of leather or rubber between the sole and the heel part of the shoe to form
the heel. Now the object of my invention is to make the sole and heel piece all
in one; and thereby effect a great saving in labour and cost and also prevent a
great waste of material, and add to the durability of the sole.
I form my improved entire soles by casting them in one piece which entirely
obviates the necessity of cementing or attaching an additional piece of rubber or
other material which has hitherto been necessary, thereby effecting a considerable
Baving of labour and obtaining perfect solidity and firmness of attachment which
has hitherto not been achieved in rubber soles intended to be attached to boots
and shoes with leather or other insoles.
In some cases I also add to the sole a toe piece similarly formed to that of the
heel, whereby greater durability is obtained; the toe. part being that part of the
sole which is most subject to wear.
And in order that my said invention may be clearly understood, reference is
hereby made to the accompanying drawings, in which similar letters of reference
indicate corresponding parts:-
Fig 1 is a side view of a shoe applicable for Lawn Tennis and other analogous
purposes having my improved india rubber soles attached thereto. The soles are
formed with ribs a, pyramids b, and plain toe and heel surface pieces c c, as shewn
in Fig 2. In addition to the toe and heel pieces I form the wearing surface
piece d, where the tread is heaviest ; and such surfaces may be placed at other
parts of the sole where required.
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:-
The use and manufacture of India Rubber soles for boots and shoes made in one
piece and provided with ridges and surface pieces in the manner substantially as
herein before described and shewn on drawings Figs 1 and 2.
