Abstract

244,712. Spezial - Werk - Zeugfabrik Feuerbach Ges. Dec. 20, 1924, [Convention date]. Ratchet gearing.-The pawls of a reversible ratchet wrench are arranged in the head parallel to the axis of rotation in a circle round it and are provided on part of their circumference with teeth engaging teeth on the inner surface of an adjusting ring for the purpose of reversing the pawls. The pawls f are urged by springs g into engagement with notches h in the driver b. Rotation of the pawls on their axes through 180‹ for reversing the action of the wrench is effected by the adjusting ring e having internal toothed portions k engaging spaces i between teeth on the circumference of the pawls, the ends of the toothed sections k limiting the rotation of the ring.
