Abstract

601,071. Apparatus for recording and reproducing sound on films. LAFFON Y SOTO, A., and SELGAS Y MARIN, E. DE. Aug. 30, 1945, No. 22361. Convention date, Jan. 30. [Class 40 (ii)] In an apparatus for recording and reproducing sound on film, constant speed of the film past the sound gate is maintained by passing the film over a drum 1 mounted on the upper end of a vertical shaft 3, supported by a central pivot 9, and having a flywheel 7 at its lower end. The shaft 3 is driven by a member 4 encircling the shaft 3, and coupled to it by springs 13 connecting a cross-bar 12 on the member 4 to a cross-bar 11 on the shaft 3.
