Abstract

504,499. Photographic cameras. ZEISS IKON AKT.-GES. May 4, 1938, No. 13345. Convention date, May 4, 1937. [Class 98 (i)] A ring mounted coaxially on the objective shutter of a photographic roll film camera advances the film through a reciprocatory lever system, winds the shutter and advances an exposure counter. A catch 3 on the coaxial ring 2 operates a lever 5 against the action of the spring 4. The lever 5 is pivoted on a lever 6 which acts through a free wheel drive 7 on gears 8, 9 and a film-advancing drum 10. The gear wheel 11 of the film take-up spool is similarly connected. An eccentric 12 is connected to the free wheel drive 7 and actuates the pawl 13 of the counter 15.
