MENTS IN THE MANUFACTURE OF WATERPROOF FABRICS
Year: 1884

Rubber Manufacturers do hereby declare the nature of my invention for IMPROVE-
MENTS IN THE MANUFACTURE OF WATERPROOF FABRICS to be as follows:-
Having invented and patented (29 February 1884, No 4127) a process for
producing a "single texture' Waterproof Fabric with a transparent coloured
surface, I now propose to apply the same invention to "double textures" i.e. cloths
having the waterproof material inserted between two fabrics, with the twofold
object of producing a good appearance and as a means of identification and
recognition of the prooting; so that certain standards being introduced, each
having a distinct colour imparted to it; the same may be known and recognized
by the said distinct colour.
In carrying out my invention, I dissolve aniline or other transparent colours in
alcohol or in any other liquid which will act as a solvent to the colouring matter
and at the same time will mix freely with the naphtha wherein the rubber is
dissolved in the process of preparing it for spreading upon the cloth and then
mixing with the "dough" or prepared rubber, such a proportion of the colouring
matter as will impart a proper degree of colour to the body of the material or
"dough" which is then applied to the two fabrics in the usual well-known manner
by spreading and afterwards "vulcanized
or cured" also as usual.

Having invented and patented (29 February 1884, No 4127) a process for
producing a single texture Waterproof Fabric with a transparent coloured
surface, I now propose to apply the same invention to "double textures" i.e. cloths
having the waterproof material inserted between two fabrics with the twofold
object of producing a good appearance and as a means of identification and
recognition of the proofing, so that certain standards being introduced, each having
a distinct colour imparted to it, the same may be known and recognized by the
Baid distinct colour.
In carrying out my invention, I dissolve aniline or other transparent colours in
alcohol, or in any other liquid which will act as a solvent to the colouring matter
and at the same time will mix freely with the naphtha wherein the rubber is

by spreading and afterwards " vulcanized"

"
The above is the process which I have found to produce the best results, but the
materials used may be different and the mode of manufacture may be varied by
grinding the colours with the dough.
<<
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I wish it to be
understood that I am aware that an opaque coloured "proofing" has been applied
to woven fabrics, such "proofing" being made by mixing opaque" pigment
colours with the rubber in forming the dough, but to such process I desire to lay
no claim as it will not produce the effect which constitutes one of the chief features
of my invention, but I declare that what I claim as my invention is
The manufacture of a transparent coloured "proofing" material, or mixture, and
the application thereof to the fabric, substantially as heretofore described.
