Abstract

238,161. Harper, R. Oct. 13, 1924, [Convention date]. Variable-speed gearing comprises a double driving pulley 8 carrying planet pinions 17 which mesh with a sun gear 19 fast on a fixed shaft 3 and with a sun gear 14 fast to a sleeve 13 which is thus driven at twice the speed of the pulley 8. A belt 34 on a pulley 22 fast on the sleeve 13 may transmit the drive. The belt 34 may be moved to the pulley 8 for reduced speed. The speed may be further multiplied by a second set of planet pinions 30 carried by the sleeve 13 and meshing with a gear 31 fast on the fixed shaft 3 and with a gear 32 fast on a second sleeve 26. A pulley 38 transmits a drive multiplied four times. Pulleys 35, 21, 4 are loose.
