Abstract
26,087. Balloch, G. R. Nov. 9. Driving-mechanism, variable-speed, for bicycles. The hub A, which is mounted to run on ball bearings B, B', is provided internally with toothed rings F, F<1> with which may be caused to gear the wheels G, G<1> to give different speeds. The wheels G, G' are eccentrically mounted on balls H carried by a disc I, which may be slid along the hollow axle E to throw the wheels G, G<1> in and out of gear. Motion is imparted to the wheels G, G<1> from the usual chain-wheel D, which is mounted on the ball bearings E, E<1> and connected to a wheel D<1>, which always remains in gear with internal teeth G<2> on the wheel G<1>. The gearing is varied by moving the disc I along the hollow axle C by means of the longitudinal rod J and a series of bell-crank levers and rods carried along the frame to a lever pivoted on the handle-bar. In a modification, the disc I is fixed and the pinion G always remains in gear with the wheel F. The wheel F' is, however, carried by a sleeve which slides over the extended hub of the chain-wheel, and is provided with clutch-teeth for engaging corresponding clutch teeth on the driving-wheel hub. When the clutch teeth are in engagement the hub rotates at the same speed as the chain-wheel, but when the wheel F<1> is slid into engagement with the wheel G<1> a different speed is obtained.
