Abstract

383,658. Feeding films in recording or reproducing sound. CASTELLAIN, A. P., 8, Clydesdale Mansions, Bayswater, London. July 28, 1931, No. 21564. [Class 40 (ii).] In recording sound on, or reproducing it from, films which pass over and drive a drum associated with a flywheel and are driven by a sprocket, this sprocket is resiliently connected with the driving source, and friction means are provided to prevent " hunting " in the system comprising the flywheel, sprocket, and connecting film. In the arrangement shown the film is driven by a sprocket wheel 1 with sliding engagement with a key on a shaft 5 supported in a hollow shaft 4 mounted in a casing 11 and driven by a worm 2 from a source of power. The hollow shaft 4 drives the shaft 5 by one or two spiral springs 6, 7 secured at one end to the inner circumference of a flanged pulley 8 and at the other end to a collar 9, preferably with flattened sides, fixed to the hub of a gear wheel 10 secured to the shaft 5. The sprocket _ is pressed by a spring 15 against a friction disc 13 fixed to the casing 11 so that oscillations due to irregularities in the drive through the springs are rapidly damped. Further damping may be effected by oil filling the space between the spiral springs.
