Abstract

17,403. Laffond, A. Aug. 21, 1911, [Convention date]. Converting reciprocating into rotary motion. -For imparting a continuous rotary drive to the back wheel of a bicycle by a reciprocating motion of the cranks, the axle a is connected bv oppositely-acting one-way clutches e, e' to toothed rings f, f<1>, the ring f gearing directly with a pinion h on an intermediate shaft c carrying the driving chain-wheel j and the ring f<1> gearing with a pinion i on the intermediate shaft through a pinion g. In this way, depression of the forward crank d<1> drives the wheel j through the gearing f<1>, g, i, and the depression of the rear crank d drives the chainwheel through the gearing f, h. When desired, the cranks may be used in the ordinary way as rotary members, and the drive is then maintained by the three wheels f<1>, g, i.
