Abstract

1,105,947. Ratchet gearing. EASTMAN KODAK CO. 24 Sept., 1965 [9 Oct., 1964], No. 40712/65. Heading F2Q. Pivoted nylon pawls 13, 14 are loaded by a common spring 21 against a metal driven diso 12 to continuously rotate the same in a clockwise direction and are alternately slid anticlockwise on the disc before recommencing a driving stroke by the ends 32, 33 of an oscillating rocker arm 26. The pawls 13, 14 have wedge-shaped ends which engage a corresponding groove in the disc 12 and are concentric with the pin and slot pivots 16, 17 of the pawls.
