ABSTRACT:
A print-washing tank with generally rectangular spirally-looped pipes in parallel vertical arrays, fed by a horizontal input conduit in the upper portion of the tank, the arms of the pipes having holes to spray photographic prints on both sides with jets of water, the prints being supported between the vertical spray loops, using either wire baskets or being supported directly in the narrow vertical spaces between the spirally looped pipes. A drain pipe array is provided at the bottom of the tank, having a plurality of widely spaced intake ports and leading to a vertical siphon exit conduit near the back wall of the tank and which may be either inside the tank or may be located externally. The top loop of the siphon drain system is located slightly below the level of the water input pipe.
