Abstract

376,868. Optical sound-recording and reproducing apparatus. BROWN, F., Langley Works, Long Acre, London. April 30, 1931, No. 12762. [Class 40 (ii).] In sound film recording and reproducing apparatus, the film is guided through the gate 5 by rollers 6, 7 arranged at the entrance and exit, each roller having end flanges 9 engaging the film and being divided transversely and the flange of the portion 6b held resiliently against the edge of the film by a spring 13. Each roller is freely mounted on a headed spindle 10 screwed into a part 12 of the gate and by means of which the film can be adjusted laterally in the gate. The central part of the divided rollers may be recessed to be clear of the film and a washer may be interposed between the two parts of the roller.
