COMPLETE SPECIFICATION. -
An Improved Photographic Print Washer.
1, GEORGE FREDERICK FIRTH, of Oakleigh House, Stanley, near Wakefield,
in the County of York, Woollen Merchant, 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 refers to an improved photographic print washer.
Fig. 1. is a side elevation showing my improved photographic print washer.
Fig. 2. is an end elevation in section of my improved photographic print
washer.
Fig. 3. is a plan showing inside of bottom tank (when top tank is removed) and
Joose trays placed therein.
Fig. 4. is an end view of trays showing how they rest upon one another.
According to my invention I employ top and bottom tanks A and B, which fit
the one into the other, and are provided with syphons C and D. The prints are
placed in loose perforated trays E, contained in a frame or cage F, which is
removable from the lower tank B, by means of handles or cross bars G.
The trays E are preferably arranged in the cage or frame F so as to rest
one upon another, with the exception of the lower tray, which is supported by
means of projections H, upon the frame or cage F. Water is poured into the top
tank A, and from there into the lower tank B, by means of the syphon C, and is
discharged from the lower tank, by means of the syphon D.
The prints are alternately soaked and drained, thereby effectually washing the
prints.
My said improved washer is made of zinc, tin, or other suitable metal or material
and is applicable for washing all kinds of prints, the images or pictures of which
have been "fixed" through the agency of any medium soluble in water.
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. A photographic print washer consisting in the combination of tanks A and B,
having syphons C and D, the tank B being fitted or provided with a series of loose

page_text: perforated trays E for holding the prints during the washing operation, sub-
stantially as set forth.
2. In a photographic print washer the construction and arrangement of trays, for
holding the prints during the washing operation, substantially as set forth.
3. A photographic print washer constructed and operating so that the prints
after being placed in the tank, can be alternately soaked and drained for any
required length of time, substantially as set forth.
