Purposes in Monochrome or Polychrome.
JOSEPH BROWN, Artist Cluny Lodge, London Street Norbiton Kingston-on-Thames,
Surrey, do hereby declare the nature of my said invention to be as follows:-
This Invention relates to a preparation of Gelatine and flexible Gums on a
Temporary flexible basis, which Temporary flexible basis is finally removed-leaving
the photographic image supported by a transparent flexible skin or film of Gelatine
& Gums for the purposes of producing Negative Pictures or Positive Pictures
either in Monochrome or when transferred to a rigid support for Coloring purposes
at the or on the backside of positive picture.
The manner in which I carry out my Invention is as follows-I take a sheet of
prepared Paper or other suitable flexible material-on this aforesaid flexible material
I proceed to lay a coating of Gelatine-rendered insoluble. The surface of this―
Gelatinous flexible paper-I now coat with a layer of liquid caoutchouc or India
Rubber, to which I add a mineral oil or grease, glycerine or wax. On the surface
of this Gummy preparation I place a coating or layer of Cotton wool that has
been prepared with acid and dissolved in Etherated Alcohol. I then coat this
cotton surface, or surface of diluted Cotton with a layer of Gelatine either clear
or colored as desired. When sufficiently set I then coat with a solution of Gelatine
& Bromide of Silver. I sometimes place the layer of Gelatine containing the
Bromide of Silver direct on the layer of dissolved Cotton wool leaving out the
intermediate layer of clear or coloured Gelatine. This is now ready to receive
the Photographic image and be treated in the ordinary Photographic manner; after
the image is developed and the Film cleansed from the various Chemicals used in the
development of the Photographic image--I leave the Film with its image upon it to
dry. When dry I either strip it of its temporary paper or other flexible support or I
place it face downwards on a rigid support and then strip away its temporary paper
or other flexible support, leaving me in either case a transparent film or Škin. I
sometimes use this in the production of negative pictures or in the production of
positive pictures or I apply color at the backside of such positive pictures when trans-
fered on its rigid support.

JOSEPH BROWN Cluny Lodge, London Street Norbiton, Kingston-on-Thames
Artist I do hereby declare the nature of my said 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 the preparation of Gelatine and other flexible Gums on a
temporary flexible support or basis which temporary support is finally removed after
the Photographic image has been obtained either in its Monochromatic condition or
after colors has been applied and then transferred to a rigid support such as Card,
Glass, Wood, or any other suitable material.
The manner in which I carry out my invention is as follows-I take a sheet of
Paper or other suitable flexible material on this flexible materia! I lay a coating of
Gelatine rendered insoluble, when dry, I lay another conting of liquid caoutchouc or
India Rubber to which I add a mineral oil or Grease or Wax, when dry I then coat
with a Solution o fCotton Wool that has been prepared with acid and dissolved in
Etheral Alchol. After this is dry I again coat it with a Solution of Gelatine cither
Clear or Colored and on the surface of this layer of Gelatine I place a layer of
Bromide of Silver Emulsion. I sometimes omit this thin layer of Gelatine, and
place the Bromide of Silver Emulsion direct on the preparation of the dissolved Cotton
Wool as above. The prepared Bromide Emulsion surface is ready to receive the
Monochromatic Photographic Image I proceed for the Polychromatic to place
colors at the surface of the Monochromatics Image before removing the film of Gelatine
& Gums from its flexible support after the colors are dry I proceed to transfer the film
on to a rigid support and then remove the flexible temporary support.
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
The Process herein mentioned in the preparation of Gelatinous films for Photo-
graphic purposes in Monochrome or in Polychrome as herein set forth.
