COMPLETE SPECIFICATION.
Washing Photographic Silver and other Prints.
BIRT ACRES 131 Richmond Road Hackney London N.E. Photographer 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:-
My invention relates to the washing of photographic silver and other prints, the
object of my invention is that the prints may be kept in an upright position in a tank
or other suitable vessel of water, in such a manner that they could not stick together
double up, become crumpled or in any other way damaged.
To secure this object I construct two light frames of wire or any other suitable
material (if of metal, protected by a coating of water-proof enamel, paint or varnish)
a little larger than the size of the print intended to be washed, the top of one of the
frames having a shoulder projecting at each end to allow of its being suspended in a
tank or other suitable vessel, each of these frames is covered with a network of wire
or other suitable material; the two frames are hinged together at the base so as to
open and shut in book form. When closed a simple clasp or any other suitable
fastening keeps the two frames closed in position. The networks being adjusted to
the frame in such a manner that they (the two networks) cannot touch each other,
but leave a space of about one-eighth of an inch betweeen their entire surfaces, in
which space the print to be washed is kept in position-the contacts of the two
frames when the apparatus is closed preventing the print slipping out of the
apparatus.

in Specification.
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
1st. The hinging together of the frames substantially as described.
2nd. That the two networks which confine the print in position are not allowed to
touch each other, but leave a clear space between them-the print to be washed being
kept in position by the frames as before described.
