Abstract

311,950. Morton, D. May 29, 1928. Variable-speed gearing comprises a series arrangement of two-speed epicyclic gears in which change from speed reduction to solid drive is effected by an automatic centrifugal clutch which does not transmit the load, the clutches becoming operative in succession. In Fig. 1, shaft 1 drives sleeve 21 through one of these gear units. Stepped planets 7, 8 carried by a drum 10 mesh with sun gears 6, 20 on the shaft 1 and sleeve 21 respectively. The drum 10 being kept from turning backwards by a roller detent 12, Fig. 3, reduced driving takes place through train 6, 7, 8, 20. When, owing to reduced load, the sleeve 21 accelerates, clutch shoes 29 are moved out by centrifugal force so that the drum 10 is drawn round at the same speed as the whole train. The arcuate shoes 29 are supported upon pins 28 which slide outwards in slots 27 against the pull of springs 30. The slots 27, which are formed in the arms of a spider 26 fast on sleeve 21, are inclined to increase the grip of the clutch after engagement. The second train 7<1>, 8<1>, 10<1>, &c. is similar to the first, the clutch being tuned for a different speed of engagement. Forward and reversed driving are obtained by moving a combined gear and clutch 53 to right and left respectively of Fig. 1.
