Abstract

344,514. Kinematograph apparatus. KINGSTON, A. W., 9, Newman Street, Oxford Street, and SPICERS, Ltd., 19, New Bridge Street, both in London. Dec. 7, 1929, No. 37614. [Class 97 (i).] The take-up sprocket and the take-up spool are driven from the spindle of the feed spool by means of a plate 91 receiving crank pins 69, 92, 93, carried by a pinion 68 and by discs 94, 95 on the spindles. The plate 91 may be triangular, and its middle part may be cut away. A main shaft 62 of the mechanism may be driven by a clockwork motor or by hand, and may drive the pinion 68 by means of pinions 65, 66, 67. Alternatively, an electric motor may drive a shaft 63 geared to the shaft 62. The apparatus may be provided with two lenses &c., as described in Specification 344,511, so that it may be used as a camera or as a projector.
