Improvements in and connected with Washing Photographic Prints,
Plates, Films and the like.
RICHARD GREENLAND, 40, Cambridge Street, Farmers Road, Camberwell, S.E.,
Cycle Frame Maker, do hereby declare the nature of this invention to be as
follows:-
1
A description of the apparatus to carry out the process, is as follows. A light
tight portable tank, with detachable lid, containing a sieve like tray, raised
slightly from the bottom, and made in compartments to hold prints, plates,
lengths of film, and the like, seperately. Each compartment is covered on all
sides, and the bottom, with a fine wire netting, to prevent water driving them
against each other. A tube is fixed to tank, the other end of tube, can be
attached to any ordinary water tap. Covering the entrance of water, "inside,"
is a director to send a steady, even, current, across the tank, flowing over the prints,
plates, and the like, in its course. The water then passes over a partition,
which being lower than the top of tray," prevents water dislodging anything,
in the compartments. The water then passes out of washer, through holes in the
bottom, between the partition, and the end of the tank. The partition slopes at
an angle of 45° degrees, from the bottom of tank, towards the top, and away
from entrance of water, the holes are placed under partition. Any light entering
through holes, is prevented from coming in contact, with sensitive matter, in the
tank, by the partition, which slopes, directly over them. The tank is raised
slightly on V shaped legs.

RICHARD GREENLAND, 40, Cambridge Street, Camberwell, London, S.E., Cycle
Frame Maker, 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:-
A tank or dish for washing photographic prints, plates, films and the like as
shown in Fig. 1, containing a tray or trays as Fig. 3. Fig. 4 shows a side
elevation of Fig. 3. The said trays to be made in seperate compartments, as
shown at D, Fig. 3. Each compartment having all four sides hinged, shown at b,
and covered with a wire netting. The framework of the bottom of tray V Fig. 3
forms spindles for the sides B1, B2, B3, and B4 to work upon. The said sides

page_text: are looped round V at O. B1 goes under B2 and over B4. B2 goes over B1
and over B3. B3 goes under B2 and under B4. B4 goes under B1, and
over B 3. Projections are shown at W which prevents sides falling on to prints
in the compartments. The said sides of tray 6 can be opened to place prints and
the like in and closed and fastened as shown in Fig. 3 at 6, by this means the
water passing under and over the said prints cannot dislodge them, or allow them
to come in contact with each other. The bottom of tray is covered with netting
as shown at f, Fig. 3. Fig. 2 is section A, A, of Fig. 1. A tube G is fitted to
tank, the other end of tube can be fitted to any ordinary water tap. Water pass-
ing down the said tube g into a director or guide E "as shown in Fig. 1, and
Fig. 2," to break the force and send a steady current along the tank flowing over
and under the prints in its course. The water then passes over a partition, weir,
or overfall H, which slopes at an angle as shown in Fig. 2, from the bottom
of tank towards the top and away from entrance of water. Holes are placed in
the bottom of tank as shown at K, under partition H, to let off the exhaust
water. Any light that might enter exhaust holes K is prevented from coming in
contact with sensitive matter in the tank by the said weir or overfall or partition H
which slopes directly over the said exhaust holes K. The tank or dish is fitted
with a light tight lid M, Fig. 2. The tank is raised upon legs as shown at P,
Fig. 2.
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. Placing a partition, weir, or overfall, in a dish or tank and by having means
of exhaust between said weir, partition or overfall and the end of said tank.
2. Trays made in seperate compartments, each compartment having all four
sides hinged which can be opened to place prints and the like in, and closed and
fastened as shown in the accompanying drawings. The bottom and all the sides
are covered with wire netting.
3. Placing the said tray in a tank or dish which has a weir, partition, or over-
fall, and means of exhaust fitted at the one end, and a distributor or guide at the
other end.
