Abstract

322,234. 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. - Talking motionpicture apparatus comprising a picture projector and an apparatus for reproducing sound by a photo-electric system, is provided with means for detachably coupling apparatus of the gramophone or phonograph type, employing grooved records. By this means, either system of sound reproduction may be used in association with the projection of kinematograph pictures. The invention is shown as embodied in an apparatus in which a single stand carries a picture, projector and photo-electric apparatus for reproducing sound recorded on the picture film, a driving motor, and a disc record machine which is detachably mounted on the stand and is adapted to be driven by the same motor. This apparatus is fully described and shown in Specification 322,233. Specifications 271,810,; 320,864, [Class 80 (ii), Gearing, Variable-speed &c.], 320,872 and 322,235 also are referred to.
