IMPROVEMENTS IN THE MANUFACTURE OF SOLES FOR LAWN TENNIS, CRICKET AND OTHER BOOTS AND SHOES
Year: 1884

page_text: I HERBERT ISAAC LIVERMORE of Basinghall Street in the City of London do
hereby declare the nature of the said Invention for IMPROVEMENTS IN THE
MANUFACTURE OF SOLES FOR LAWN TENNIS, CRICKET AND OTHER BOOTS AND
SHOES to be as follows:-
"
The invention has for its object improvements in the manufacture of soles for
lawn tennis, cricket and other boots and shoes requiring roughened surfaces
whereby an efficient foothold is obtained combined with durability.
For this purpose I take raw caoutchouc preferably that known in the trade as
Fine Para Rubber" in the condition in which it is imported into this country
and mix therewith by the aid of the ordinary crushing rollers or by means of a
masticator any suitable vulcanizing material or substance and if desired coloring
matter or pigment.
I then pass the compound of caoutchouc and vulcanizing and coloring material
through ordinary crushing rollers and the caoutchouc compound issues therefrom
in the form of a rough porous tape, strip or sheet which is thus colored and
prepared for vulcanization.
Tapes, strips or sheets of caoutchouc prepared as above described are then cut
into the forms required for the soles of boots and shoes and afterwards submitted
to the ordinary vulcanizing process, which soles are then fixed in position by
means of india rubber solution or in any other convenient manner, as is well
understood.

do hereby declare the nature of the said Invention for IMPROVEMENTS IN THE
MANUFACTURE OF SOLES FOR LAWN TENNIS, CRICKET AND OTHER 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 :-
The invention has for its object improvements in the manufacture of soles for
lawn tennis, cricket and other boots and shoes requiring roughened surfaces,
whereby an efficient foothold is obtained combined with durability.
For this purpose I take raw caoutchouc preferably that known in the trade as
"Fine Para Rubber" in the condition in which it is imported into this country
and after cleansing it, mix therewith by the aid of the ordinary mixing rollers or
by means of a masticator any suitable vulcanizing material or substance and if
desired coloring matter or 'pigment.
I then pass the compound of caoutchouc, and vulcanizing and coloring material
several times through ordinary crushing rollers and the caoutchouc compound
issues therefrom in the form of a rough porous tape, strip or sheet which is thus
colored and prepared for vulcanization..
Tapes strips or sheets of caoutchouc prepared as above described are then cut
into the forms required for the soles of boots and shoes, and afterwards submitted
to the ordinary vulcanizing process, which soles are then fixed in position by
means of india rubber solution by sewing or in any other convenient manner as is
well understood.
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 Improvements in the manufacture of soles for lawn tennis, cricket and
other boots and shoes substantially as herein described.
