456,705. Turning-gear. BOSCH AKT.- GES., R., 4, Militõrstrasse, Stuttgart, Germany. March 9, 1936, No. 6977. Convention date, March 9, 1935. [Class 7 (v)] In a starter comprising a flywheel or the like driven from a cranking handle b through a shaft a and toothed 01 other gearing, the slots d of a pin- and-slot connection between the handle b and the shaft a are such that the handle can assume a normal position, in which automatic disengagement of the handle is effected when the engine starts, or a second position, in which the shaft a can be turned backwards by means of the handle if the engine comes to rest with the starter clutch or pinion still in engagement. As shown, the slots d have an axial portion e, and a plunger g acted on by a spring h is arranged in the hollow shaft a. In normal use, the handle a is inserted until it touches the plunger g, the pins c being in the inclined part of the slots d. To enable the shaft a to be turned backwards, the handle b is pushed in against the pressure of the spring h to bring the pins c into the axial portion e of the slots. In a modification, the pins c are provided on the shaft a and the slots d, plunger g and spring h in the hollow hub of the cranking handle.
