Abstract
An apparatus for use in the development of photographic film comprising a tank for holding a substantially constant temperature bath. Two axles carrying wheels or rollers thereon are journaled in the side walls of the tank. The first axle and thereby wheels or rollers attached thereto is driven by a motor. The second axle has a plurality of positions relative to the first where it may be journaled. Thus the apparatus may be adapted to receive a plurality of sizes of drum processors used in the processing of photographic film by variously positioning the second axle. Thus the drum processor resting on the wheels is rotated through the bath as the driven axle is turned to thus maintain the processor and its contents near the bath temperature.
Claims10
Apparatus for use in the chemical development of photographic film comprising
- (a) a tank for holding liquid at a selected temperature,
- (b) means for circulating liquid within the tank controlling the temperature of the liquid,
- (c) a driven axle with at least two wheels thereon of equal diameter journaled across the tank,
- (d) a movable idler axle with at least two wheels of equal diameter thereon,
- (e) a plurality of means for receiving the idler axle arranged in a plurality of journaled positions parallel to the driven axle,
- (f) means for driving the driven axle to turn the wheels attached thereto, and
- (g) said wheels movable along the axles without loss of turning engagement,
- whereby the apparatus may be used to rotate and maintain the temperature of a processing drum placed upon the wheels, the distance between the axles being adjusted to insure adequate immersion of the drum in the liquid.
