885,058. Engine starter drives. GARBE, LAHMEYER & CO. A.G. July 12, 1960 [July 13, 1959], No. 24204/60. Class 7(5). A starter drive incorporates an overrunning clutch and is characterized in that the clutch comprises needle rollers 42, 65 located between inner and outer sleeves and in that the outer sleeve is journalled for rotation in a bearing of the motor casing whilst the inner sleeve carries the starter pinion 29, 58, the two sleeves being connected for simultaneous axial movement through the bearing. In Fig. I the inner bore of the threaded bushing 18 is formed with a worm groove 21 which engages a similar worm thread 22 of high pitch formed on the surface of the motor shaft 15. When the starter button is pressed the detent sleeve 28 is moved in a conventional manner and the detent ball 24 moves through the aperture 23 and out of the groove 25. Figs. 2 and 3 show a modification. A series of V-shaped wire springs 69 are connected at one end to the cage 64 and lie within grooves 57 in the outer sleeve. These springs maintain a peripheral preloading of the one-way clutch.
