ABSTRACT:
A photographic processing apparatus for uniformly processing roll film and photographic sheet material in a rolling stainless steel tank. The tank rolls back and forth along a platform that is tilted one way, and then the other, by means of an air bellows placed under one end of the platform. A mechanical air valve automatically shuts and opens to inflate and deflate the bellows. The apparatus can be placed in a constant temperature water bath. Electrical shock hazards are avoided since none of the electrical components are located in or near the water bath.
