Abstract

332,505. Petit, J. P. Dec. 22, 1928, [Convention date]. Expanding pulleys for flat belts comprise tread segments 7 passing through radial slots 6 in inner discs 5 and supported in spiral grooves 10 in outer discs 9. The spirally-grooved disc 9 is clamped against the slotted disc 5 at each side of the pulley by a ring or pair of rings 12 screwed on to a central hub-member 1, so that all the discs can be unlocked by unscrewing a single ring. The thrust of the screwed ring or rings 12 is taken on an annular member 2 keyed to the hub 1 in the middle of the pulley.
