1237. Dougill, A. Jan. 17. Variable - speed gearing.-Relates to variablespeed friction disk driving-mechanism for bicycles, tricycle, and light three-wheeled carriages driven by a motor or motors, and comprises the use of eccentric bearings for the shaft carrying the driven disk. In the arrangement shown in Figs. 1 and 2, the motor A is provided with two fly-wheels F, F<1>, which drive friction disks F<2>, F<3>, the latter being put in or out of gear by means of eccentricallymounted bearings G carrying the driven shafts D, D<1>, which are connected to one another and to the road-wheel axle by chain, belt, or like gearing. In a modification, only the fly-wheel F<1> farthest from the axle is employed, the shaft D<1> being geared directly to the axle, and in another only the fly-wheel F nearest to the axle is retained.
