Abstract: 396,908. Variable - speed gearing ; driving superchargers. FAIREY AVIATION CO., Ltd., Cranford Lane, Hayes, Middlesex, and FORSYTH, A. G., Venlaw, Burdon Lane, Cheam, Surrey. June 8, 1932, No. 16196. [Class 80 (ii).] Two-speed epicyclic gearing for driving a supercharger shaft 22, Fig. 1, of an internalcombustion engine upon an aircraft comprises a ratchet wheel 25 and a pawl 27, Fig. 3, for preventing the backward rotation of a sun gear 23 on low speed, and means for withdrawing the pawl and preventing it from clicking on high speed. Secured to the engine crank shaft 12, Fig. 1, is an internal gear 14 and clutch drum 13. Planets 15 meshing with the gears 14, 23 are supported on a spider 16 connected by a sleeve 17 to a splined gear 18 geared to the shaft 22 through a train 19, 20, 21. The sun gear 23 is connected to the ratchet wheel 25 by a sleeve 24 passing over the shaft 12 and under the sleeve 17. On low speed, the pawl 27, Fig. 3, which is supported on a fixed pivot 26 and biased by a spring 28, engages the wheel 25 so that the gear 23 forms a fulcrum gear around which the planets 15 roll, the spider 16 &c. being driven at a definite reduced speed. This position is shown in Fig. 1. Clutch shoes 29, Fig. 2, carried by the spider 16 are adapted to be expanded by the simultaneous rocking of two right and left handed nuts 31. When a control sleeve 35 is moved to the left from the position of Fig. 1, two levers 33 are tilted and so rock the nuts 31 to expand the shoes 29 into engagement with the drum 13 so that the epicyclic gearing turns solid and the gear 18 turns at the same speed as the shaft 12. In this changing operation, a projecting pin 41, Fig. 2, on one of a pair of strikers 38 strikes the end of a spring dog 42, with a tapered nose 42a, Fig. 3, which is thrust into an eccentric opening 43 in the pawl 27. The opening 43 is moved to concentricity with the dog 42, which has the effect of withdrawing the pawl 27 from the ratchet wheel 25. A lever 40, Fig. 2, is used to effect the speed change. Between the dog 42, Fig. 4, and its coned noseend 42a is a spring 44, and between a sleeve upon the nose-end and a fixed socket 26a is a retraction spring 45.
