Abstract

344,819. Kinematograph apparatus. VISIONTONE TALKING PICTURES, Ltd., St. Lawrence House, Trump Street, King Street, London. Dec. 5, 1929, No. 37387. Convention date, Dec. 6, 1928. [Class 97 (i).] A self-contained combined gramophone and kinematograph apparatus includes as a unit construction a cabinet 14 (see plan, Fig. 3), carrying on a baseplate x a motor 18 driving a vertical shaft 36 geared to the spindle 76 of the gramophone turntable, and on a vertical panel 25 the driving sprockets and the feed and take-up spools for the picture film, the spools being driven from the motor through horizontal shafts 108, 100 fitted with clutches y which are alternatively coupled and uncoupled by operating a lever 116. The arrangement is such that one of the spools can be clutched to the prime mover for feeding and the other for rewinding the film. The light source 126, when in the position shown in Fig. 1, projects light downwardly through the film which is moved in the horizontal plane over a gate 66 by continuous feed sprockets 62, 64, and an intermittent sprocket 139. Prisms (not shown) deflect the beam through a lens system 128 mounted on a front door 26 hinged along its bottom edge and carrying the shutter 130. When the door is raised to the closed position, the shutter is placed in engagement with its driving shaft by a spring clutch 132. The light source may be pivoted so that it may be turned to the inoperative position shown in Fig. 3, and may be removed from the apparatus by withdrawing the pivot pin 124. The sprocket shafts 92 include ratchet couplings 90 and drive the spool shafts 100, 108 through belts 96, 104.
