Abstract
A sequential flow washer for photographic prints and film consisting of a tank having sidewalls, endwalls and a base, said tank being divided into multiple compartments by a series of alternately arranged baffles located between the sidewalls, one of said baffles being an overflow baffle and the adjacent baffle being an underflow baffle. From an intake manifold, water overflows one sidewall into the first of the multiple compartments and then flows down through said compartment which is created by an underflow baffle and up into the next compartment defined by an overflow baffle and over the top thereof and continues serially through compartments created by alternating underflow and overflow baffles and out over the opposite sidewall into an exit manifold. The upper edges of both sidewalls are preferably slotted to allow for the uniform flow of water into and out of the adjacent manifolds.
