PROVISIONAL SPECIFICATION.
An Improved Washing Apparatus for Photographic Prints.
I WILLIAM MORRISON SIMPSON of 41 Elphinstone Road Hastings in the
County of Sussex Engineer do hereby declare the nature of this invention to
be as follows:-
My invention consists of a tank in which trays are arranged horizontally one
above another with a suitable space between each. The trays consist of rectangular
frames across which tape is interlaced so as to form a suitable lattice-work on which
the prints to be washed are supported. One side of the framework is made of tube,
preferably brass, of suitable substance. The other sides are made of stout wire
suitably bent and attached to the tube at a short distance from each end thereof. In
one corner of the tank I place an upright supply-pipe having a row of holes along
one side of it at a suitable distance apart, and in an adjacent corner of the tank I
place an upright bearing piece pierced with holes corresponding oppositely with
those in the supply-pipe. The holes form bearings into which the short projections
of the ends of the frame-tubes are inserted. The ends of the frame-tubes bearing
in the supply-pipe are left open and the opposite ends are closed. Small jet-holes
are bored at intervals in the frame-tubes in the direction of the plane of the frames.
I provide suitable step-pieces or feet to support the sides of the frames opposite
to the tubes so that the trays may be parallel to each other. The frames are made
each one a little larger than the one immediately below it, and the tank is preferably
made wider at the top than at the bottom. The frames can be turned from the
horizontal to a vertical position, turning in the bearings before mentioned. The
action is as follows. The prints to be washed are placed on the frames or trays,
beginning with the lowest tray. The other trays are in the vertical position while
this is being done and are turned down successively as required. Water is then
turned on to the supply-pipe and thence traversing the frame-tubes issues from the
small jet-holes and gradually fills the tank. When the tank is filled there will be a
constant circulation of water between each tray of prints. I provide a suitable
overflow with means for emptying the tank when required, such as a syphon with
an air valve or tap at the top of the bend, to act either as overflow or syphon as
may be desired.
