Abstract
549,315. Feeding sound films. VIKING FILMS, Ltd., and HUMPHRISS, E. A. June 30, 1941, No. 8201. [Class 97 (i)] A film passing, in a sound recording camera, between a toothed sprocket and a recording drum, is led over one or more guides or pulleys so as to change its direction, and the curvature of the guides &c. and the tension of the film are such that the natural resilience of the film causes it to assume a curved path in the spaces between the guides &c. As shown, the film is fed by a sprocket 3 and passes round pulleys 4, 5, 6, 7 to a recording drum 8 ; thence it passes to a sprocket 11 and over a roller 12 to the sprocket 3. The pulley 7 is carried on an arm 10 that may be weighted and adjustable to determine the film tension. The' shaft of the sprocket 11 may be motor driven', through a resilient coupling, and the sprocket 3 may be driven tnerefrom through gears 15, 16, 17.
