JOSEPH BROWN 3 Stanley Terrace Norbiton Kingston-on-Thames Surrey "Artist"
do hereby declare the nature of my said invention to be as follows:-
This invention has for its object Improvements in the use of Transparent
Gelatine as a substitute for Glass or Paper for the support of the Sensitive Gelatinous
films used for photographic purposes.
My mode of proceeding is as follows. I take a sheet of paper which I coat with a
layer of Gelatine, This when dry I coat with another layer of Wax or Grease
On this prepared surface I proceed to place a sheet of insensitive transparent Gelatine
by means of a vacuum, This sheet of Gelatine after it has sufficiently dried on its
support I proceed to coat with a layer of any of the usual sensitive Photoc. Emulsion's
This is left to dry and then cut up to any required size. This prepared Gelatine
attached to its paper, support is now ready to receive the photoc. image I now
proceed to develope the image by any of the well known methods after the image is
developed I proceed to place the photoc. image face downwards on a sheet of Glass
or other prepared surface when sufficiently dry I take away the Paper support and
leave the coated Gelatine to dry compleatly. When dry I lift up the sheet of
Gelatine which carries with it the photoc. image and which is now ready to be printed
from by any of the usual methods.
