AN IMPROVED MANUFACTURE OF ARTIFICIAL LEATHER
Year: 1884

page_text: I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for "AN IMPROVED
MANUFACTURE OF ARTIFICIAL LEATHER a communication to me from abroad by
Henry Schwabacher of 24 Rue Taitbout, Paris, France Gentleman to be as
follows:-
"
This Invention relates to a new process of manufacturing artificial leather having
the appearance, strength, suppleness, elasticity and durability of real leather.
This new product which I designate Cuir Parisien is prepared in the following
manner:-
I take or manufacture a cotton fabric of which the warp threads are very
slightly twisted (like those used for candle wicks) and the weft twisted as usual,
but finer than the warp; this fabric, when woven, is strongly teaseled on both
sides in order to completely conceal the woven appearance of the fabric. The fabric
thus made is immersed in the following preparation which is mixed and emulsioned
in a perfectly homogeneous manner. The quantities given are calculated to coat
a surface of 100 metres of fabric.
Decoction of linseed
Rabbit skin glue
Boiled, linseed oil previously prepared for being emulsioned
Coloring matter (leather color)

The fabric suitably impregnated with this preparation is stretched on a polished
zine plate and laid upon a steam heated hot-plate; the desiccation is continued
until the aqueous portion is entirely evaporated. The fabric thus treated is then
very readily detached from the zinc plate, from the surface of which it will have
received a polished appearance. In this condition the artificial leather is susceptible

embossing, shagreening, gilding, moroccoing, paring, coloring, stamping, sewing,
glazing, &c, and it may be employed for all purposes for which animal leather is
used, particularly by upholsterers, trunk makers, hatters, coach and harness makers,
boot makers, military outfitters, book binders, etc.

same is to be performed, to be particularly described and ascertained in and by the
following statement :-

The fabric suitably impregnated with this preparation is stretched on a polished
zinc plate and laid upon a steam heated hot plute; the desiccation being continued
until the aqueous portion is entirely evaporated. The fabric thus treated is then
very readily detached from the zinc plate, from the surface of which it will have
received a polished appearance. In this condition the artificial leather is susceptible

page_text: of being finished in all the various ways of finishing natural leather viz:-
embossing, shagreening, gilding moroccoing, paring, colouring, stamping, sewing,
glazing & and it may be employed for all purposes for which animal leather is used,
particularly by upholsterers, trunk makers, hatters, coach and harness makers, boot
makers, hatters, coach and harness makers, boot makers military outfitters, book
binders ect.
The artificial leather thus produced is capable of being used as a substitute for
ordinary leather in all its various applications, it having the same appearance and
possessing the same strength, suppleness, elasticity and durability as leather, while
it can moreover be produced at a very cheap rate.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that what
I claim is
The manufacture of artificial leather by impregnating a cotton fabric specially
prepared as herein described, with a composition made of the ingredients and
prepared in the manner herein specified, and drying the fabric in contact with a
heated polished metal plate substantially as herein set forth.
Dated this 1st day of August 1885.
