Abstract
A watertight enclosure for washing photographic material. The enclosure has individual print chambers (24), that are separated by dividers (8), (10). The dividers (8), (10), are sectioned into levels with each level having slots (22), (23) at predetermined intervals along the length of each divider that accept rods (9), (11) to hold the material being washed at the top of the washer. The rods (9), (10) also suspend the material in the water at all levels. The washers inlet chamber (2) is suspended above the bottom of the washer so that water and residual chemical can pass under and away from the print chambers (24) as it exits the washer.
