India Rubber Compositions, Farina, Starch, and French Chalk, and
Fabrics Producing a Bronzed Appearance.
I, JAMES FREDERICK KELLY, of 148 Monier Road, Old Ford, Bow, in the
County of Middlesex, "India Rubber Worker 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 :-
My invention relates to fabrics coated with india rubber, and india rubber
compositions after the said fabrics or the like has been through the ordinary
process of vulcanizing, liquid curing or vapour curing, to produce a bronzed
appearance.
The surface of the fabric, proofed article, or the like coated with india rubber or
india rubber composition, is passed over a rollar partly immersed in a trough
containing the coloured dye required, and passing the said fabric over an ordinary
steam cylinder to dry.
My invention consists of a process for producing a bronzed appearance of fabrics
coated with india rubber and india rubber compositions, by aniline dyes, dissolved in
strong solution of Alcohol Spirits, Nitric Acid, Wood Naptha, and Spirits of
Turpentine, by passing the said fabric over a roller partly immersed in a trough con-
taining the dye, and passing over a steam cylinder to dry, and when dry a bronzed
appearance is produced, it is then recoated with india rubber, or india rubber com-
position, the said fabric is then subjected to the process of being vulcanized, liquid
cured, or vapour cured.
My solution for dissolving aniline dyes consist of the following ingredients, viz.:—
2 oz. Alchol Spirits.
1 oz. Wood Naptha.
10 drops of Nitric Acid.
1 oz. Spirits of Turpentine.
The aforesaid provides the proportions required to make four ounces of liquid, which
will dye 3 pounds of india rubber or india rubber composition.
The process of dyeing before vulcanizing, liquid curing, or vapour curing; the
india rubber is subjected to steam washing, drying and masticating, it is then reduced
with naptha mixed in mixing rollers, as in common use, and when ready, the dye of
whatever colour required is added, in the solution as herein before described.
My mode of dyeing farina, starch, and french chalk, before being applied to fabrics
coated with india rubber, or india rubber compositions are by dissolving aniline dyes
in the aforesaid solution.
The farina, starch, or french chalk is then saturated and evaporated by heat which
leaves the farina, starch, or french chalk dyed in the required colour.
The advantage of my invention are that fabrics of any description, treated in the

page_text: aforesaid manner with the aniline dyes dissolved in the aforesaid solution, are
more attractive, transparent, and are less liable to decomposition under ordinary
summer temperature than the method of colouring by any other process now in use.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First The combination of the solution of Alcohol Spirits, Nitric Acid, Wood
Naptha, and Spirits of Turpentine, in the proportions described or otherwise, to
dissolve the Aniline dyes of any colour, for dyeing and otherwise treating india
rubber, india rubber compositions, farina, starch and french chalk and fabrics, to
produce a bronzed appearance, substantially as herein described.
Secondly I claim the process of producing the bronzed appearance on the fabrics
coated with india rubber, or india rubber compositions, by the aniline dye of any
colour, dissolved in the solution of Alcohol Spirits, Nitric Acid, Wood Naptha, and
Spirits of Turpentine, in the proportions described, by passing the coated surface of
the fabric over a roller partly immersed in a trough containing the dye in the solution,
and thence passing over a steam cylinder to dry, and when dry, a bronzed appearance
is produced, it is then recoated with india rubber, or india rubber composition,
and afterwards vulcanized, liquid cured, or vapour cured, substantially as herein
described.
Thirdly claim the advantage of my invention for treating fabrics, as they are
more attractive in appearance, transparent, and it leaves an entire coat of rubber on
the surface, and is less liable to decomposition than the present method of colouring
any like material, substantially as herein described.
