IMPROVEMENTS IN INNER SOLES FOR BOOTS AND SHOES OR OTHER COVERINGS FOR THE FEET
Year: 1884

page_text: I THOMAS HENRY HARRISON of 40 Hatton Garden in the County of Middlesex
and 242 Notre Dame Street Montreal Canada Optician do hereby declare the
nature of said invention for "IMPROVEMENTS IN INNER SOLES FOR BOOTS AND
SHOES OR OTHER COVERINGS FOR THE FEET" to be as follows:-
This invention relates to an improved manufacture of inner soles for boots and
shoes or other coverings for the feet whether such soles be intended to be used as
loose soles to be placed inside the boot or shoe or as a fixed inner sole to be united
by stitches or otherwise to the uppers.
The chief object of my invention is to obtain a perfectly damp proof durable
and ventilated sole of a neater appearance than the ordinary cork soles hitherto
employed. In carrying out my invention I take a sheet composed of rubber with
which is incorporated any well known fibre such for example as manila hemp and
which is afterwards vulcanized. With this sheet which I call "sheet vulcanite
fibre "I combine a sheet of cork or of what is known as celluloid or sheets of cork
and of celluloid and I unite the said sheets by metal eyelets, the eyelet holes serving
to promote ventilation, or by stitching or otherwise. When the sole is to be united
to the uppers I prepare them for that operation by perforating them round the
edges so that the stitching needle can be readily passed through the perforations
the whole forming a useful and entirely new article of manufacture suitable for
ready attachment to the uppers of slippers and such like coverings for the feet by
any person.

and 242 Notre Dame Street Montreal Canada Optician do hereby declare the nature
of my invention for "IMPROVEMENTS IN INNER SOLES FOR BOOTS AND SHOES OR

to be particularly described and ascertained in and by the following statement:—
This Invention relates to an improved manufacture of inner soles for boots and
shoes or other coverings for the feet whether such soles be intended to be used as
loose soles to be placed inside the boot or shoe or as a fixed inner sole to be
permanently united by stitches or otherwise to the uppers and has for its object
the obtaining an inner sole which shall be perfectly damp proof and more durable
whilst presenting a neater appearance than the ordinary cork soles hitherto
employed.

My said invention consists in the manufacture of inner soles for boots and shoes
or other coverings for the feet from the compound known as Vulcanite fibre
consisting of caoutchouc or rubber having incorporated therewith a fibrous material
such for example as Manilla Hemp which compound is rolled into sheets and
afterwards vulcanized or from the compound known as Celluloid reduced to a sheet
form from which sheets I cut out the soles by punches or otherwise. I sometimes
combine together in one sole a sheet of the vulcanite fibre and a sheet of Celluloid
or I combine with either of the said sheets a sheet of cork and where the soles are
composed of two or more sheets of material I unite the said sheets by metal eyelets
(the eyelet holes serving to promote ventilation) or by stitching or otherwise I
sometimes when greater warmth is required face the said soles with a layer of cloth,
wool, Tamarac bark or other like material and where ventilation is required I
perforate the said soles for that purpose. When the sole is intended to be
permanently united to the uppers of a foot. covering such as a Slipper for example
I prepare it for that operation by perforating it round the edges so that the stitching
needle employed in uniting it to the uppers can be readily passed through the
perforations the operation being thereby greatly facilitated.
i
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. The application and use to and in the manufacture of inner soles for boots
and shoes or other coverings for the feet of Vulcanite fibre or of celluloid in a sheet
form whether perforated or not substantially as hereinbefore described.
2. An inner sole for boots and shoes or other coverings for the feet composed of
vulcanite fibre or of celluloid in a sheet form either separately or combined together
or combined with a sheet of cork the said sheets when two or more are employed
being united by metal eyelets or by stitching or otherwise as hereinbefore
described.
3. An inner sole composed of the materials or compounds specified coated or
faced with cloth wool Tamarac bark or other like substance for the purpose
herein before described.

round the edges for facilitating the stitching of the same to the uppers of slippers
or other like coverings for the feet as herein before described.
