Abstract

615,215. Ratchet clutches. JACK & HEINTZ, Inc. Oct. 19, 1945, No. 27502. Convention date, Nov. 2, 1944. [Class 80 (ii)] [Also in Group XXVII] In a reversible ratchet clutch mechanism a driving member 12 has symmetrically pivoted centrifugal pawls 22, 23, Fig. 4, which coact with one side of symmetrical stops 25, 26 formed on the inner surface of a driven drum 13. The driving and driven members are mounted in spaced bearings 8, 9 and 10, 11, respectively, in the two parts 6, 7 of a split housing. Thus, if the housing parts are separated, the pawls 22, 23 can be turned to engage the opposite sides of the stops 25, 26 to permit a one-way drive in the opposite direction. As shown, applied to an aeroplane engine turning gear, an emergency hand crank 29, Fig. 1, drives an inertia fly-wheel 2 through a flexible shaft 5, the ratchet clutch, bevel gears 4, 3 and the normal turning motor 1, which during such normal turning therefore drives the fly-wheel but not the crank. Specification 566,176 is referred to.
