Abstract

159,754. Hatcher, E. C., and Rooke, T. Feb. 4, 1920. Gearing varying in ratio as drive is applied to one or other terminal shaft.-Two worm or helical trains in series are used with a ratchet clutch and applied as hand or power starting-gear for internal-combustion) engines. A worm d upon the driving-shaft a in line with the engine shaft b meshes with two worm-wheels e upon spindles g mounted transversely in a casing n. The spindles g are connected by skew gear pairs f to perpendicular spindles i also in the casing. Worms j upon the spindles i mesh with a worm-wheel k fast on the shaft b. When the shaft a is actuated, the casing n is prevented from turning backwards by a ratchet clutch t, and the shaft b is driven slowly in the same direction. When the shaft b is driven by its engine, the gearing turns solid, the clutch t overrunning. Any resistance upon the shaft a would cause the casing n to overrun the shaft b. Such effect is limited by having the worm d movable axially to bring clutch dogs u into action. Alternatively, a ratchet clutch between the shafts a and b may be used for this purpose. A yielding spring latch s, Fig. 1, or magnetic friction clutch may be used to prevent damage due to a backfire.
