Abstract

8908. Davies, P. A. C. April 16. Variable-speed gearing for motor-vehicles comprises a cone 5 secured to a shaft 3 and encircled by a band 11, which is gripped between the cone 5 and a cone 4 slidable on a parallel shaft 2. A spring 6 encircles the shaft 2 and presses against the cone 4 so as to maintain engagement with the band 11, which is movable to vary the speed. Reversed driving may be obtained by a chain 17 connecting a chain-wheel 16 on the shaft 2 to a chain-wheel 18 on a shaft 19 in line with the shaft 3 and adapted to be connected thereto by a clutch 20.
