Abstract

322,235. Beatty, W. E., (Bell Telephone Laboratories, Inc.). July 20, 1928. Divided on 321,148. Drawings to Specification. Combined working of sound-reproducing apparatus with kinematographs.-To provide a compact talking motion-picture apparatus which enables picture projection to be accompanied by soundreproduction either from an optical film record or from a gramophone record, both types of soundreproducing apparatus are mounted together with a picture projector, on a common base. The invention is shown as embodied in an apparatus, having a common driving motor, which is fully described and shown in Specification 322,233. Specifications 271,810; 320,864, [Class 80 (ii), Gearing, Variable-speed &c.], 321,148, and 322,234 also are referred to.
