    • 16,573. Williams, J. N. July 24, 1912, [Convention date]. Motor - wheels. - A wheel of the suspension type encloses an independent revolving-cylinder motor, which drives the wheel through a clutch and reducing- gearing. Fig. 2 shows an axial section of the motor wheel as applied to a bicycle, and Fig. 3 shows a side elevation of the motor. Three cylinders I, II, III arc bolted to a crank casing 1 which turns upon a crank-shaft 2 fixed in the forks 3. The separated and independent spoke flanges 35, 40 are mounted upon and held apart by thrust bearings 36, 42, so as to maintain the tension of the spokes 37 and the rigidity of the wheel. The rotation of the crank case is transmitted to the wheel through toothed gearing and a clutch on the non-rotating stud 19. The clutch surfaces consist of cone - shaped annular projections and grooves, and are operated by axial movement of the stud 19. The exhaust valves 10 in the cylinder head are operated by levers 11, 52, a link 13 and cams 51 geared to the crank casing by means of epicyclic gearing 46, 47. A cap 8 secured to the cylinder head forms an exhaust chamber, the exhaust escaping through holes 6. Electric current for the ignition is transmitted from the wire 56 through an insulated segment 55 and contact 58.
