Abstract

373,547. Sound reproducing apparatus associated with kinematographs. ZEISS IKON AKT.-GES., 72, Schandauerstrasse, Dresden, Germany. Nov. 18, 1931, No. 32007. Convention date, Nov. 25, 1930. [Class 40 (ii).] A sound-film reproducer and its driving motor are combined together to form a unitary structure which is adapted to be mounted on the platform of a kinematograph projector. As shown in Fig. 1, a sound reproducer 2 is mounted with its driving motor 3 on a common baseplate 1. The motor 3 drives the sound-film sprocket 4 and the shaft 5 of the motor 3 carries an axially adjustable chain wheel 6 which drives the kinematograph projector by means of a chain 9. The complete unit is mounted on the platform 8 of the kinematograph projector. In one modification, Fig. 4, the driving motor 3 is directly secured to the sound reproducer 2 which is mounted upon a baseplate 1 secured to the platform 8 of the kinematograph projector. The driving shaft of the motor 3 rotates an intermediate shaft 11 through gearing 12, 13, and on this shaft 11 is an axially adjustable chain wheel 6 which drives the kinematograph projector.
