ABSTRACT:
A photographic developing tank is described to aid in processing light-sensitized photographic materials such as paper, plates, or film. The tank is formed as a unitary body structure having an enclosed water cavity extending between and defined by integral walls of the tank structure. A top wall of the structure includes two or more indentations to form integral photographic processing trays. The indentations extend downwardly into the water cavity to bottom walls that are spaced upwardly from the unitary base wall of the tank. Drain passageways extend from the indentations outward through the cavity to the exterior of the tank. Petcocks are provided at the outer ends of the passageways to allow individual drainage of the fluid contents from the respective trays. Inlet and discharge ports are provided that enable water to flow through the water cavity. The water while in the water cavity completely surrounds the peripheral walls of the indentations as well as the bottom walls thereof. The indentation walls are of uniform thickness so heat is transferred evenly through the walls to the processing chemicals held within the indentations. Consequently the chemicals in the various trays are held to the same temperature to improve the photographic developing process.
