I, PATRICK MILLAR MATTHEW Jr., of the Victoria Rubber Company Leith Walk,
Edinburgh, in the County of Midlothian, India Rubber Manufacturer do hereby
declare the nature of this invention to be as follows:-
These Improvements as hereinafter described, relate to the manufacture of Water-
proof Fabrics, composed of India Rubber in combination with Cotton, Woolen, Silk
or other textile material, and are principally applicable to the lighter textures such as
are employed in the manufacture of garments and domestic articles.
For several years Waterproof textures similar to those above-mentioned, have been
made by coating the various fabrics with a thin film of India Rubber, and thereafter
applying to the India Rubber surface a coating of Farina or other substance capable
of producing a lustrous or ornainental effect.
By my process the India Rubber surface of such textures is, previous to being
coated with the farina or other ornamental powder, covered with some light fabric of
an open nature, such as lace or similar material, in such a manner that the greater
portion of the Rubber surface remains exposed. This network or open fabric is
attached to the Rubber surface while the latter is still "tacky" or adhesive & is firmly
united to it by passing the combined fabrics between a pair of suitable rollers.
The farina or other ornamental powder is then spread over the whole surface, &
adheres to those portions of the Rubber which are still exposed.
The fabric may be vulcanized by the well known liquid process either immediately
before the application of the farina or ornamental powder, or thereafter. It may

page_text: also be vulcanized in the ordinary manner by the vapour of a solution of Bisulphide
of Carbon & Chloride of Sulphur.
The waterproof textures manufactured by my process have an exceedingly rich &
silky appearance and are greatly superior in durability to those presently in use, which
have their entire surface coated or covered with farina or other powders, in so far as
these ornamental substances are by my process protected from friction by the over-
lying network of lace or other material.
Having described my invention & the means which appear to me best adapted for
carrying it out, I declare that what 1 claim is the method of producing India
Rubber Waterproof fabrics, having an ornamental surface, substantially as hereinbefore
described.

Improvements in the Manufacture of India Rubber Waterproof
Textile Fabrics.
I, PATRICK MILLAR MATTHEW Jr. of The Victoria Rubber Co. Leith Walk in the
city of Edinburgh & county of Midlothian, India Rubber Manufacturer 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 :-
These improvements as hereinafter described relate to the manufacture of Water-
proof fabrics, composed of India Rubber in combination with cotton, woolen, silk &
other textile materials, and are principally applicable to textures of a light description
such as those used in the manufacture of garments, aprons and other domestic
articles.
Fer several years it has been common practice to manufacture Waterproof fabrics
by apprying to them a thin filmn of India Rubber, & thereafter coating the surface
of the said India Rubber, either before or after vulcanization, with Farina or other
substance capable of producing a silky, lustrous or ornamental effect. By my process
the India Rubber surface of such textures, is, previous to being coated with the Farina
or other ornamental substance, covered with some light fabric of an open nature, such
as lace or similar material, in such a manner that a considerable portion of the India
Rubber surface remains exposed. This network or open fabric which may be composed
of silk, wool, cotton, or any fibrous substance capable of being woven in a manner
suitable for the purpose above described, is attached to the India Rubber surface,
while the latter is still tacky or adhesive, by bringing the two fabrics in contact with
each other under considerable pressure, which may be applied by rollers or other suit-
able means.
If greater adhesion be required, the network or open fabric may,
previous to being brought in contact with the India Rubber surface of the cloth, be
rendered adhesive on one side by a very thin coating of a solution of India Rubber
or other adhesive substance, which may be applied by any of the well known means
of applying such solutions.
If the Farina or other ornamental substance is to be applied before vulcani-
zation, I then spread it over the whole surface by any of the means in common
use for applying such substances. A sufficient portion of the Farina or other
substance thus becomes attached to those portions of the Rubber surface, which
are still exposed, & the surplus or loose granules may be brushed off in the
ordinary way. I prefer to vulcanize the fabric, either by bringing it in contact
with a solution of Chloride of Sulphur in Bisulphide of Carbon, or by the vapour of
said solution, but any of the methods of vulcanization may be employed which are
commonly used in the manufacture of the ordinary farina-coated or "electric" proofed
fabrics.
If the Farina or other ornamental substance is to be applied after vulcanization, I
pass the exposed India Rubber surface of the fabric over a roller revolving in the
vulcanizing solution above mentioned, & apply the Farina or other ornamental

page_text: substance to it immediately thereafter, & while the Rubber surface is still soft &
adhesive from the action of the solution. The surplus may then be brushed off as
before mentioned & the fabric is complete.
Waterproof textures manufactured by my process, have an exceedingly rich &
silky appearance, & are greatly superior in durability, to those presently in use,
which have their entire surface coated or covered with Farina or other powder in so
far as these ornamental substances are by my process protected from friction by the
overlying network of lace or other material.
Having now particularly described and ascertained the nature of my said
Invention, & in what manner the same is to be performed, I declare that what
I claim is
The production of India Rubber Waterproof fabrics having an ornamental surface,
in the manner and by the means, substantially as hereinbefore set forth and described.
