Abstract: 374,687. Variable-speed gearing. GOVAN, W., 36, Well Street, West Paisley. Aug. 11, 1931, No. 22661. [Classes 80 (i) and 80 (ii).] Continuously variable toothed gearing comprises. two toothed members or b, discs a, Fig. 1,. with parallel teeth in sectors a<1>, b<1> as shown in Fig. 9. The discs are geared together so that the toothed sectors upon them come into mesh successively with a pinion c which has laminated teeth which adapt themselves to obliquity in a position such as that shown in Fig. 9. A driving-shaft f has splined connections with gears a<3>, b<3> which drive the discs a, b simultaneously. These discs are supported on brackets d, g adapted to slide on guides e, e<1>, e<2> so that the discs are moved in unison in opposite directions over the pinion c which thus engages the teeth of both discs at the same distance radially of each disc. The speed of a driven shaft i is varied by turning a hand-wheel e<5>, Fig. 2, which actuates a right-and left-hand screw e3, e<4> engaging the brackets d, g respectively. As a toothed sector b<1>, Fig. 9, of disc b moves across below the pinion c, toothed laminations on plates m, Fig. 11, constituting the pinion turn relatively and as they leave the sector b<1> they are just in proper relative position to engage the advancing edges of a sector a<1>, Fig. 1, on the disc a above the pinion. The plates m of the pinion c are constrained to swing angularly in union by being connected by lugs q, Figs. 12 and 13, on the peripheries of two sectors o of a sphere which turn about central pivots p in the body n of the sphere and are effective balance levers. The sphere body n is fast on the shaft i and side-plates r support the plates m laterally. The shaft i may drive and the shaft f be driven. According to the Provisional Specification, reversed driving may be effected by moving the disc centres beyond the pinion, and automatic control may be effected by a governor.
