Abstract
471,893. Kinematograph apparatus. MAYTUM, J. A., and SMITH, L. Feb. 11, 1936, No. 4157. [Class 97 (i)] A beater feed mechanism is operated by a crank cam or the like 9 located between the beater 13, Fig. 1, and a pivoted arm 11 bearing a shutter 12, the crank &c. being connected to the beater and the shutter arm by links 19 and 18 respectively so that rotation of the crank oscillates both shutter and beater. The film 2, fed by a sprocket 3, is pulled intermittently through the gate 4 by the beater 13, which is preferably in the form of a segment of a cycloid, and passes over a take-up sprocket 4 rotating on the same axis as the beater. The driven shaft 8 of the crank 9 is coupled to the sprocket 5 by a six-to-one reduction gear, and each of the sprockets 3 and 5 has a circumference equal to the length of six pictures so that the film is advanced by one step for each complete turn of the crank 9. The gate 4, Fig. 5, has an aperture a, and a pressure plate 22 carrying pins 23 and pressed against a front plate 26 by springs 28.
