Abstract
316,255. PathÚ CinÚma, Anciens Etablissements PathÚ FrÞres. July 26, 1928, [Convention date]. Kinematograph apparatus. - In an intermittent - feed mechanism comprising claws 2 carried by a link 1 moved by a crank pin 3, the crank pin carries a member 8 which controls the vertical movement of t h e link so that the claws enter and leave the film perforations horizontally. As shown, the pin 3 engages a slot in a member 10 secured to the link 1 and thereby effects the horizontal movements of the claws. The end of the link 1 is kept in engagement with the cam member 8 by a spring 9, and the cam surfaces 13, 14 are shaped to produce the required horizontal movements of insertion and withdrawal, and to increase the speed of the feed movements.
