Abstract

599,081. Kinematograph apparatus. AVIMO, Ltd., and STEVENS, H. C. M. May 4, 1945, No. 11391. [Class 97 (i)] The invention comprises a film feed claw at the outer end of an arm, a rotary disc adapted to form a pair of cams, a stationary member with guides at right angles, and means engaging the cams and guides and adapted to transmit movement from the cams to the arm to give a rectangular claw movement. As shown in elevation in Fig. 1 and in section in Fig. 3, the claw is formed on a bent portion k of an arm i. These two pins m, n project into slots g and h in the plate f and into two cam tracks d, e formed in the face of a disc h secured to the driving spindle c. The pin m passes through a hole m<1> in the arm i and the pin n through a slot n<1>.
