page_text: I, THEODORE BIRNBAUM, of Wick Lane Rubber Works, Bow, in the County of
Middlesex, India Rubber Manufacturer, do hereby declare the nature of this
invention to be as follows:-
-
This invention relates to an improved manufacture of striped and other water-
proof fabrics.
In the Specification of Letters Patent granted to me dated June 6th 1893
No. 11110 I described a method of obtaining a shot effect by the use of farina
superposed on a coloured ground.
In the Specification of a subsequent Patent also granted to
me dated
January 10th 1894 No. 561 I have described a method of obtaining on ornamental
waterproof fabrics effects or patterns by applying stripes or streaks of dough
differing in colour from the colour forming the ground thereof, the stripes or
streaks being applied by means of a comb or other suitable apparatus.
The object of my present invention is to obtain a heightened or improved
ornamental effect on such fabrics by the following means: that is to say.
I spread a coloured rubber ground upon the fabric to be waterproofed.
I then superimpose upon this coloured ground a coloured dough striping, or a dye
striping.
I then finish this so treated surface with farina, or equivalent light material,
mixed with a coloured metallic powder, in suitable relative proportions according
to the material and the effect to be produced.
The fine metallic powders are selected of suitable shades and grades in order to
attain the desired effects in relation to the coloured grounds to which they are to
be applied.
When it is desired to produce plain coloured ornamental effects, instead of
stripings, as surfaces for the waterproof fabrics I apply the metallic powders
accordingly on the ground.
Amongst the advantages attendant on the use of metallic powders in the manner
I have described in preference to the sole use of farina for the purpose, are that
the metallic powders take a firmer hold upon the ground rubber surface than is
found to be the case with dyed farina; that the metallic powders are insoluble in
water and are therefore not absorbent and are practically unaffected by moisture,
whilst effects of greatly enhanced beauty and lustre can be attained by the use of
such metallic powders, than by the use of farina alone.
The metallic powders are preferably mixed with a suitable proportion of farina, or
equivalent light matter, to lessen their density, for the reason that in most cases
too great density would obscure the coloured ground too much, and further such
addition serves to adulterate the metallic powder, or to bring it down to a required
shade,

page_text: I, THEODORE BIRNBAUM, of Wick Lane Rubber Works, Bow, in the County of
Middlesex, 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:-

ornamental effect on such fabrics by the following means: that is to say: -
I spread a coloured rubber ground upon the fabric to be waterproofed.
I then superimpose upon this coloured ground a coloured dough striping, or a dye
striping, such as by means of the method of application described in the Specification
of my Letters Patent dated December 23rd 1896 No. 29556.
I then finish this so treated surface with farina, or equivalent light material,
mixed with a coloured metallic powder, in suitable relative proportions according
to the material and the effect to be produced.
The fine metallic powders are selected of suitable shades and grades in order to
attain the desired effects in relation to the coloured grounds to which they are to

too great density would obscure the coloured ground too much, and further such
addition serves to adulterate the metallic powder, or to bring it down to a required
shade,
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
1. The improved manufacture of waterproof fabrics by spreading a coloured
rubber ground upon a fabric to be waterproofed, then superimposing upon this
coloured rubber ground a coloured dough striping, or a dye striping, and finishing

page_text: this treated surface with farina or the like mixed with coloured metallic powder in
suitable shades and proportions, substantially as and for the purpose set forth.
2. The method of obtaining improved ornamental effects upon india rubber
waterproof fabrics by the application upon coloured rubber grounds of coloured
dough stripings, or alternatively dye stripings and mixed farina (or the like) and
metallic powder finishings, as set forth.
3. The production of plain coloured ornamental effects upon india rubber water-
proof fabrics by the applications of metallic powders admixed with farina or the
like upon the coloured rubber grounds spread on the fabric to be waterproofed,
as set forth.
