Abstract
A claw feed mechanism for a motion picture camera for intermittently advancing film for exposure. A first end of an elongated, light-weight film feeding pin is pivotally coupled to a first crank. The film feeding pin includes an advancing taper at the second end thereof for engaging with and advancing the film. A second crank includes a guide for guiding the film feeding pin. The first and second cranks are mutually eccentrically driven so that the film feeder pin reciprocates with respect to the guide, while the film feeder pin and the guide synchronously pivot so that the advancing taper on the film feeder pin defines an elliptical path thereby intermittently engaging with and advancing the film for exposure.
