Title: Processing apparatus for photographic material
IPC: G03D13/00
Filed: 1945-06-08
Abstract: 594,688. Photographic processing apparatus. DALY, W. J. June 8, 1945, No. 14535. [Class 98 (ii)] Apparatus for processing photographic materials comprises endless transporting means which is adapted to move the materials sequentially through a number of treatment stations and which controls mechanism for stopping or moving the means so as to halt materials successively at, and move them between, treatment stations. The apparatus shown consists of a light-tight cabinet made in two sections, the lower 1 containing three processing baths 4, 6, 9 with intermediate rinsing baths, and the upper 2 in which hot air from a dryer 12 carried on the exterior of the cabinet is blown over the films. The film carriers comprise vertical rods 38 connecting upper and lower sets of braced cross-rods 36 of which the lower rods carry fixed film clips 39 and the upper film clips 43 on spring leaves 41, 42 and hang by hooks 35 on equally spaced cross-rods 18 carried between two endless chains as 16 on opposite side walls of the cabinet. The chains are fed over sprockets 26, 27 to form five equally spaced bights to lower the carriers into, and raise them out of, the various baths. The controlling mechanism in a housing 53 comprises (1) an electric motor 54 which through chain 57 drives a shaft 59 engaging the chains 16 and (2) a relaycontrolled timing device 66 which determines the period of immersion of the carriers in the processing tanks. The motor circuit being closed by an external switch (not shown). The cycle of operations is as follows. A carrier containing undeveloped cut-films is placed on a, hanger rod 48 straddling the cabinet and as the chain moves forward a cross-rod 18 on the chain engages the carrier hooks 35 and transports the carrier into the developing tank 4. At this stage another cross-rod arrives at the drying station 10 and a pin on the end of the rod closes a switch 72 which causes a solenoid 63 to operate brake shoes 61 on the motor 54 and also to depress a switch 79, thus starting the timing device 66 and also de-energizing a solenoid 80 so that its spring-biassed armature 71 moves away from a contact 70, first breaking the motor supply circuit and then making through switch 84 the circuit of the heater 14 and fan 15 of the dryer. After a pre-set interval, the timer 66 re-energizes the solenoid 80 breaking the dryer circuit and remaking the motor circuit, thus restarting the chains and allowing the switch 72 to re-open. The carrier then moves out of the first bath, is dipped momentarily into the rinsing tank and transferred to the fixing bath 6 whereafter the same cycle of events is repeated to transfer the carrier successively to the washing and drying stations 9, 10. When the films are dried, each carrier is removed from the transporting chains by a hanger rod 49. The carrier at the same time closing a switch 51 in a signal circuit to warn the operator so that he may remove the carrier through an .opening in the cabinet normally closed by a light-tight roller shutter 44.
