Abstract

334,095. Couade, M. Oct. 17, 1928, [Convention date]. Kinematograph apparatus. -A projector is provided with a curved film slide having apertures 4 for the passage of feed claws and two resilient pressers 13, 14 comprising single strips with rounded ends for holding the film in contact with the slide. These pressers may, as shown, be formed of a single sheet having an opening for the passage of light or may consist of independent strips mounted above and below the lens. The bearing surfaces of the springs may be ribbed or roughened.
