18,740. Wall, A. W. Aug. 20. Driving-mechanism.-In a two-speed hub gear for motor-cycles, tri-cars, &c., the driving-member C is coupled to a sun-pinion c<1> on a live axle or on a sleeve loose on a fixed axle. Double planetpinions d<1>, d<2> are mounted in an independent carrier or casing D, and engage with the pinion c' and with a pinion E on the hub respectively. A direct drive is obtained by clutching the driving-member to the casing by means of a clutch c<3>. Another speed is obtained by holding the casing D stationary by means of a brake F. When the direct drive is in operation, the brake F may be employed to retard the vehicle.
