Abstract

637,563. Expanding-pulley gearing. MERCIER, R. M. Dec. 16 1947, No. 33171. Convention date, Sept. 29, 1942. [Class 80 (ii)] Automatic adjustmentof the diameter of the driven pulley 15, 16 of an expanding-pulley gear is effected by the axial movement under load torque of a worm 22 engaging an output worm wheel 26. As shown, the pulley drives a shaft 18 through a friction clutch 19, which may be disengaged at any time by a roller-ended member 25 co-acting with the pulley flange 15, thus disabling the drive. The pulley flanges 15, 16 are freely mounted on the shaft 18 and are urged apart by a spring into contact respectively with the clutch member 19 and a thrust bearing 20 oppositely acted on by a sleeve 21 carrying the worm and slidably splined on the shaft 18. A spring driving pulley (not shown) is used to follow the variations of the driven pulley. In Fig. 1 (not shown) the clutch 19 is dispensed with, the driven pulley flanges being rigid with the driven shaft and worm sleeve respectively.
