Abstract

460,719. Kinematograph cameras. CANNELL, J., and SNAPE, A. Aug. 6, 1935, No. 22210. [Class 97 (i)] In apparatus wherein the film is fed intermittently by a pawl, the pawl being actuated by a connecting rod from a crank on a driving shaft and sliding over the film on its return stroke, the mechanism is controlled by an external stud or plunger engaging a rocker engaging a stop pin on the driving shaft. As shown, a pawl P, having a feed tooth p<2> and a tooth p held by a spring R in engagement with the surface of the film during the feed stroke, is pivoted in a bearing m<1> on a slide M moved in guides N by a connecting rod J and crank disc E. The shaft d<8> of the crank disc carries a stop pin d<9> engaged, when the mechanism is at rest, by a member F which may be rocked about a crossbar f<2>, and against the action of a spring f<3>, by a finger-operated plunger G.
