Abstract
339,087. Riley, P. Nov. 13, 1929. Variable-speed gearing comprises two parallel lay shafts 7, 8, constantly connected through constant-mesh gear pairs 9, 10 and 13, 12 to the coaxial driving and driven shafts 2, 6 respectively. Each lay shaft is connected by selective means to the shaft to which it is not permanently geared by a loose constant-mesh gear pair (12, 11 and 14, 15, 20 respectively) on the operation of a dog clutch (17, 21 and 16, 19 respectively) to give two speeds, and a third speed is obtained by clutching together the shafts 2, 6 by moving the double clutch 16, which is splined on the shaft 2, to the right so as to engage teeth 18 in the gear 12 integral with the driven shaft 6. A fourth speed is obtained by sliding a gear 23 splined on the lay shaft 7 into mesh with the teeth 22 on the pinion 20, 15, when drive takes place through gears 10, 9, 23, 20, 15, 14, 13 and 12. Reverse drive may be obtained by sliding interconnected gears 24, 25, which are freely rotatable on the lay shaft 8, so as to mesh with gears 20, 23, respectively, the gear 20 being free on the shaft 2 and interconnected with the pinion 15. Drive then takes place through gears 10, 9, 23, 25, 24, 20, 15, 14, 13 and 12. Alternatively, for reverse drive, a. single gear (not shown) splined on the lay shaft 8 may be brought into mesh with the gear 23, in which case a higher gear ratio is obtained.
