20,202. Perron, G., and Philippe, R. Sept. 17, 1913, [Convention date]. Turning-gear. -To prevent a fluid-pressure starting - motor from rotating before it is engaged with the engine to be started, the fluid is admitted through a pipe 11 to one side of a piston 4, which normally closes the supply passage 12 to the starting-motor, and which is connected to a pinion 1 used to engage the starting motor to the engine. When the fluid under pressure acts on the piston, it moves the pinion into full engagement before the supply passage is opened. The motor is connected to the shaft 9. The apparatus is particularly applicable to aeroplane engines.
