PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Waterproof Fabrics.
I, LOUIS FRANKENSTEIN, of the Firm of P. Frankenstein & Sons, Miller
Street, Manchester, in the County of Lancaster, Manufacturers of Waterproof
Fabrics, do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to the printing or producing ornamental designs on the
proofed surface of waterproof garments. It is difficult to print with ordinary
printing or dyeing material upon the bare surface of the rubber and this has
hitherto been coated with farina and other substances for the purpose.
My invention consists essentially in the preparation of the proofed surface for
printing upon or to receive a dye by treating with a coating or covering of bone
dust or material of similar chemical composition.
In carrying out the invention the rubber is first spread upon the cloth and the
cloth proofed in the usual way.
Upon the proofed surface thus produced I apply a fine layer or coating of bone
dust (or material of similar chemical composition) and upon the proofing when so
treated or upon the surface thus prepared I print the desired designs in any required
colours in the ordinary manner of calico printing.
The proofing is preferably vulcanised after it has been printed upon though it
may be vulcanised before if found more convenient.
Upon the printed surface may be applied another layer or coat of the proofing
of any degree of thickness to render the colour and the designs fast and prevent
them becoming spoiled by rubbing or friction.
Dated this 8th day of March 1895.

Improvements in the Manufacture of Waterproof Fabrics.
:
I, LOUIS FRANKENSTEIN, of the Firm of P. Frankenstein & Sons, Miller
Street, Manchester, in the County of Lancaster, Manufacturers of Waterproof
Fabrics 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 :-
This invention relates to printing or producing ornamental designs on the
proofed surface of waterproof garments. It is difficult to print with ordinary
printing or dyeing material upon the bare surface of the rubber and this has
hitherto been coated with farina and other substances for the purpose.
I have found that bone dust is a material that will absorb dyes or printing
materials and that when spread upon a material to which it will adhere presents a
surface upon which ordinary printing or dyeing material may be printed with
facility in any desired pattern.

page_text: My invention consists essentially in the preparation of the proofed surface for
printing upon or to receive a dye by treating with a coating or covering of bone
dust or material of similar chemical composition..
In carrying out the invention the rubber is first spread upon the cloth and the
cloth proofed in the usual way.
Upon the proofed surface thus produced whilst still in an unfinished or tacky
condition I apply a fine layer of bone dust (or material of similar chemical
composition) so as to présent à coating thereof over the whole or any desired part
of the cloth. The bone dust may be spread over the proofed side of the cloth in
any desired way to make an even layer.
Upon the surface thus prepared upon the proofed side of the cloth I print
designs of any required pattern and in any desired colours in the ordinary manner
of calico printing.
The bone dust may be applied in a white or bleached state or may be dyed to
any desired colour before being applied to the proofed surface of the cloth' in
order to give a ground of any desired colour.
The proofing is preferably vulcanised after it has been printed upon though it
may be vulcanised before if found more convenient.
Upon the printed surface may be applied another layer or coat of the proofing
of any degree of thickness to render the colour and the designs fast and prevent
them becoming spoiled by rubbing or friction.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I wish it to be understood
that I am well aware that farina and oxy-cellulose have been applied to proofed
surfaces for printing upon and I make no claim to the application of absorbent
substances per se to proofed cloths for printing designs upon but what I
élaim is :-
:-
The method or process of preparing the proofed surface of waterproof fabrics
for printing upon or to receive a dye by treating it with or applying thereto a
layer or coating of bone dust (or material of similar chemical composition)
substantially as described.
