Abstract
172,115. Svistounoff, B. Aug. 31, 1920. Variable-speed and reversing ratchet gearing comprises a swash-plate A, Figs. 1 and 2, of adjustable inclination driving through linkwork and reversible friction ratchet grips B which are characterized by the presence of rollers 37, Fig. 10, in a loose gapped ring 38, the movement of which is controlled by stops. When the gear is applied to a vehicle, a pair of reversible ratchet clutches, Fig. 2, constructed on a like principle are used for differential driving. The swash device comprises a ring 5, Figs. 5 and 7, connected by a pivot 4 so as to turn with a driving- shaft 3. This ring may be balanced. A link 7 makes connection with a sliding sleeve 9 operated to vary the speed by a link 16. An outer ballbearing supported ring 20 kept from rotating by rollers 24 engaging fixed guides 28 is universally connected to two pairs of links 25, 26, Fig. 1. Through levers 31, 32 and links 29, 27 connection is made to arms 33, Figs. 8 and 10. The rollers 37 of each grip reside between doubly-inclined recesses in the oscillating driving-member 39 and a smooth internal surface on a member 34 secured to a driven shaft 35. In order to control the direction in which the grips will drive, the cage ring 38 is provided with teeth 46, .52 adapted to coact with stops 45, 51 upon a control-ring 42 according to the setting of this ring. An arm 43 projects from the ring 42 and is normally locked by lugs 44 engaging recesses in a spring 48. To effect reversal, a cam 55 is turned pressing the spring 48 out of engagement so that a striker 56 can shift the arm 43, Fig. 9. Oneof the differential clutches C, Fig. 2, is shown. in Figs. 14 and 15. The rollers 58 are between a boss 57 on the shaft 35 and an internal drum 60 on a part-axle 61. The cage-ring 59 has teeth 66, 72 in different planes adapted to coact with stops. 65, 71 alternatively for driving in one direction or the other. Reversal is effected by sliding axially a ring 62 carrying these stops. The devices B and C, Fig. 2, are reversed simultaneously by turning a common cam-shaft 53.
