Abstract
363,381. Kinematograph apparatus. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Assignees of Siemens & Halske Akt.-Ges. ; Siemensstadt, Berlin.) Aug. 12; 1930, No. 24164. [Class 97 (i).] A film-driving means, particularly for soundrecord films, is equipped with a flywheel to ensure uniform speed and this flywheel is accelerated to its proper speed before being coupled with the film-driving mechanism and before the latter is started. A film x is fed by a main winder b over a drum a past the illuminating point z. Between the take-off spool h and a front-winder c1 and between a back-winder c2 and the take-off spool k, respectively, are inserted double tension rollers e, d. These rollers in each pair are connected by a plate f which is spring-pressed about the axis g to keep the film band tight. The front and back winders cl, c2 are elastically coupled to their shafts v1, v2 respectively by springs u. The shaft s of the main winder b is geared to a shaft t which is driven by the main driving motor o and drives through a bevel gear w the shafts v1, v2 of the front and back winders. The flywheel q is coupled with the shaft s through a magnetic coupling r1 after the flywheel has previously been accelerated to its proper speed by an auxiliary motor p. The coupling between the flywheel q and the auxiliary motor p is effected through a coupling disc a which is engaged only when the coupling r is not energized. The switching-in device for the motor o is arranged so that starting takes place simultaneously with the energizing of the coupling r. Alternatively the motor o may be arranged to accelerate the flywheel.
