ABSTRACT:
Apparatus and method for processing and treating sheets and rolls of photographic materials. Sheets are placed within a first cylindrical container and also within and outside of second cylindrical containers which coaxially fit within the first container such that a plurality of concentric sheet-mounting surfaces are formed; whereby, several different sheets of materials may be simultaneously processed and treated. A rotatable shaft is cooperatively mounted with the first container to provide for rotatably mounting the second containers and also reels loaded with films. The shaft mounts with the containers and reels along their common central axes such that when the shaft is rotated, the second container can be axially rotated and likewise, the reels can be rotated. The rotation described provides for circulation of fluids relative to the materials. A light-tight cap cooperatively fits with the first container and provides vents for passage of fluids and gases into and out of the inner chambers of the first and second containers, which are in fluid-communication with each other. At the opposite end from the cap, in the containers, additional vents are placed to cooperate with those in the cap. The apparatus provides a carrier for materials which can move the materials through stepped processing and treatment fluids. A plurality of fluids can be contained in tanks which can be temperature-controlled by an external surrounding temperature-regulated water jacket. Means are provided for washing materials in parts of the apparatus.
