Abstract

138,575. Ramsay, A., and Mort, A. Oct. 6, 1919. Variable -speed and reversing epicyclic gearing suitable for motor-vehicles comprises stepped planet gears C meshing with a sun gear B secured to driving- shaft A, with a loose internallytoothed ring D, and with a sun gear 0 loose on a driven shaft H in line with the shaft A. A sleeve J sliding on a feather on the shaft H carries clutch teeth J' adapted to engage teeth 0<1> on the gear O. A second feathered sliding sleeve K has teeth K<1> adapted to engage teeth E' on the planet carrier E. A third like sleeve P has a friction cone L adapted to engage a cone on the member D, and has also teeth P<1> adapted to engage teeth D<2> on the member D. A first or lowest speed is obtained when the ring D is held against rotation and the shaft H is clutched to the carrier E by the sleeve K. A second speed is obtained by holding the carrier E and clutching the shaft H to the gear 0. A third speed is obtained by then releasing the carrier E and holding the ring D. If now both the carrier and ring are released and the sleeve P advanced, the cone L picks up the ring D, the teeth P<1> afterwards making a positive connexion, and the gearing turns solid yielding the fourth or highest speed. For reversed driving, the ring D is clutched to the shaft H, the carrier E being held.
