Filed: 1935-02-28
Abstract: 452,789. Turning - gear. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. Feb. 28, 1935, No. 6388. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 2, 1935.] Addition to 452,788. [Class 7 (v)] In an engine starter having a pinion 11 or like wheel bodily movable transversely of its axis into and out of mesh with an engine member 12 and having a mechanical lock for holding the pinion in mesh during the cranking operation, the lock is effected and maintained, until the engine exceeds a predetermined speed, by electromagnetic means energized by the heavy current flowing through the starting- motor circuit. As shown, a gear 3, freely journalled on the shaft 2 of the starting motor and driven from the shaft 2 through a spring 5, connected to driving and driven heads 7, 49, is in constant mesh with the pinion 11, which is supported on a bearing member 54 carried by side members 55, 56 journalled on extended smooth portions of the driven head 49 and the pinion 3 to allow the pinion 11 to swing into mesh with the gear 12 when the starting motor is set in rotation. The pinion 11 is then locked in engagement with the gear 12 by a toggle 17, 21 brought into locking position by an electromagnet 65 in series with the starting- motor 1 and comprising a central polepiece 68 and an outer magnetic shell 69 mounted on a fixed pivot 71. A magnetic plunger 70 is adjustably mounted on a rod 73 provided with a crosshead slotted to engage an extension of the toggle pivot 22, and normally held in the position shown by an adjustable spring 81. A non-return valve 80 in the polepiece 68 allows the plunger 70 to move quickly into position for locking the toggle when the starting- motor circuit is closed by a switch 67. When the engine starts and the relief of the cranking load on the starting motor causes the current in the electromagnet 65 to be weakened, the plunger 70 acts as a dashpot and is returned slowly by the spring 81 until it passes an opening 76 in the tube 72. The pinion 3 may be driven through an overrunning clutch, so that the starting-motor is not accelerated above its free-running speed during the time delay period caused by the dashpot, which is adjustable by means of a needle valve 78 in a bleeder channel 77.
