ABSTRACT:
A practical vehicle for riding propelled by reciprocating occupant motion comprising a sliding seat on rails mounted on a vehicle frame in which frame three or four wheels are rotatively mounted. The mechanism comprises a chain attached by its two ends to the movable seat and which chain transmits the reciprocating motion through loose sprockets to two freewheels mounted on separate and parallel axles on bearings. On the same axles a pair of intermeshed spurgears are driven in each back and forth motion of the chain by one of the two freewheels, the one locked on its axle which is the driving element. The second spurgear is following freely the motion of the first, and vice versa. The combination of both the freewheels and the intermeshed spurgears alters the reciprocating motion to a continuous and single direction motion of the chainwheel which is attached to the extension of one of the two parallel axles. The chainwheel with a separate chain gives through the shaft supporting the rear wheels the forward propulsion to the vehicle.
