Carrier for processing photographic material and apparatus for rotating the carrier

Abstract

Apparatus for axially rotating and vertically oscillating a horizontally disposed cylindrical carrier for processing photographic material, in which a ring on one end of the carrier is supported on a rotatable eccentric and the other end of the carrier rests on rollers. The present invention relates to apparatus for oscillating a cylindrical carrier for the processing of photographic sheet or roll material. A device now marketed for processing photographic material in sheet or roll form consists of a cylindrical carrier having spaced cams located circumferentially on the outside of the carrier cylinder, or on its end caps, for oscillating the carrier about a fulcrum located in its longitudinal axis when the carrier is rotated reciprocally. Such a device is described in U.S. Pat. No. 3,688,997 issued June 13, 1972, in the name of Simon Ratowsky assignor to Monrick Holdings Limited. A device for reciprocating such a carrier is described in U.S. Pat. No. 3,735,961 issued May 29, 1973, in the name of Gordon G. Taylor assignor to Monrick Holdings Limited. The device of Taylor suffers from the disadvantage that it is expensive to manufacture and it is not adjustable for carriers of different lengths. It is an object of the present invention to provide a simplified apparatus for rotating and vertically oscillating a carrier for processing photographic material. It is a further object of the invention to provide an apparatus for rotating and vertically oscillating a carrier for processing photographic material, which will accommodate carriers of different lengths. Another object of the invention is to provide a carrier for use with such apparatus. In its broadest aspect the invention resides in apparatus for axially rotating and vertically oscillating a horizontally disposed cylindrical carrier for processing photographic material, the carrier having a ring projecting longitudinally from at least one end thereof, comprising: a frame; vertically oriented eccentric means rotatably mounted on the frame and engagable with the ring of the carrier along the trackway thereof; support means rotatably mounted on the frame and spaced from the eccentric means; and drive means to rotate the eccentric means. In another aspect the invention resides in a carrier for use with apparatus for rotating and vertically oscillating said carrier for processing photographic material, the carrier comprising a ring concentric therewith and extending longitudinally therefrom to form an inner trackway engagable with eccentric means of the apparatus. The invention also resides in apparatus for processing photographic apparatus for processing photographic material, comprising: a frame; vertically oriented eccentric means rotatably mounted on the frame; support means rotatably mounted on the frame and spaced from the eccentric means; a carrier having a cylindrical drum with a ring mounted concentrically on the drum and extending longitudinally from one end thereof to form a trackway, the eccentric means being engagable with the ring along the trackway; and drive means to rotate the eccentric means whereby the carrier is rotated and simultaneously vertically oscillated.
