I HARRY HERBERT WADDINGTON manager for Messieurs Charles Macintosh
and Company of Cambridge Street Manchester India Rubber Manufacturers
do hereby declare the nature of my invention for IMPROVEMENTS IN THE
MANUFACTURE OF WATERPROOF AND INDIA RUBBER GOODS to be as follows
I take the "proofed" cloth or the finished article (such as a playing Ball &c)
and apply a coating or covering of Farina Chalk Glitter Bronze or other powder
by making the surface sticky by the application of Varnish Vulcanizing liquor or
any other method either before during or after the process of vulcanizing, and to
the surface so coated I apply by means of a roller brush or other convenient method
a liquid varnish composed of methylated spirits of Wine or other solvent in which
18 dissolved a suitable quantity of shellao or other analogous gum for the purpose
of fastening or fixing the Farina or other Powder more firmly to the surface than
has hitherto been done. For the purpose of imparting a pleasing colour in contrast
to the uniform grey surface usually produced I add a small quantity of Aniline or
other colouring matter of the desired shade. This invention does not refer to the
production of the ordinary well known farina surface but to the fixing of the same
by a coloured varnish as above described.

I, HARRY HERBERT WADDINGTON Manager for Messrs Chas Macintosh & C° of
Cambridge St Manchester in the county of Lancaster, India Rubber Manufacturers
do hereby declare the nature of my invention for IMPROVEMENTS IN THE MANU-
FACTURE OF INDIA RUBBER & WATERPROOF GOODS, and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement
-
-
Whereas India-Rubber coated fabrics have until within the last few years been
produced with a uniform black or drab surface, but recently, efforts have been
made to produce a surface which while retaining all the advantages of the India
Rubber coating or "proofing" shall at the same time present a more pleasing
appearance than before
This object has been attained by covering the surface of
the fabric after applying the India Rubber coating, with Farina starch Flour or
other powder, either before, during or after the process of "vulcanizing" or
'curing," and while the surface is sticky or soft, so that the Farina or other powder
may adhere to the surface
Now, to the material produced by the above well-known process, there are
several material objections, the principal of which is that the Farine or other
powder is not so impressed or embedded in the body of the India-Rubber surface
that it will withstand the wear to which such goods are exposed On the contrary
it is found that in a shorter or longer time according to the manner of applying the
Farina or other powder, the latter wears off and leaves unsightly patches or bare
places where the India Rubber is not covered
In addition to this another objection is that the appearance presented by the
material treated as above described is that of a grey lustrous surface devoid of
colour and in consequence capable of little or no variety
Further the above process has not so far as I am aware been applied to the
production of an ornamental or lustrous surface upon other than woven fabrics
whilst I propose to apply my improved process to other Goods such as Toys &c.
My Improvements are as follows
I take the "proofed" cloth or the manufactured article such as a playing Ball &c
and apply a coating or covering of Farina Flour Chalk Glitter Bronze or other
powder by making the surface sticky by the application of Varnish vulcanizing
liquor or any other method either before during or after the process of vulcanizing
and to the surface so coated I apply by means of a roller brush or other convenient
method a liquid varnish which may be composed of methylated spirits of wine or
other solvent in which is dissolved a suitable quantity of shellac or other analogous
gum for the purpose of fastening or fixing the Farina or other powder more firmly
to the surface than has hitherto been effected For the purpose of imparting
pleasing colour in contrast to the uniform grey surface usually produced I add
a suitable quantity of Aniline or other colouring matter of the desired shade

page_text: This invention does not refer to the production of the ordinary well-known
Farina surface but to the fixing of the same or similarly produced surface by the
application of a coloured or uncoloured varnish substantially as above described.
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 fastening or fixing of Farina Flour Chalk Glitter Bronze or other powder
previously applied to the surface of Waterproof and India Rabber Goods, by the
application thereto of a coloured or uncoloured Varnish substantially as above
described
