Zusammenfassung:	1,027,509. Intermittent-feed mechanisms. EASTMAN KODAK Co. Feb. 15,1963 [Feb. 20, 1962], No. 6157/63. Heading G2E. [Also in Division F2] A kinematographic projector pulldown claw 29a is actuated by a cam follower (see Division F2) engaging in a groove 24 in a cam plate 20 attached to a rotating shutter 36. The claw 29a and the follower are carried on a lever 29 which rocks about a ball bearing 33 located on a fixed plate 42, a spring 31 (Figs. 5 and 7, not shown) holding the follower in engagement with the groove 24. A second spring 39 (Figs. 5 & 6, not shown) stabilizes the lever 29. The surface 27 of the cam plate 20 is contoured to lift the claw 29a clear of the film 38 during the return stroke.
