Abstract
An adapter for reciprocal lever friction drive mechanism comprises one first element as driven-driver, and one second element as the driver. The adapter consists of a pair of mechanism, one fixed at one end of the drive shaft, and the other fixed at the other end of the drive shaft, on which means of transmission of power generated is fitted. Each first element has a band shell for cylindrical friction drive engagement means fixed to it. Adjacent to each first element is disposed a second element coaxial with the first element. Each second element consists of a plural number of links pivoting about the drive shaft, and connecting with cams substantially engaging the cylindrical friction drive engagement means, and the cams pivoting on pinshafts disposed on the links. The turn of the second element in one direction engages the first element in friction drive while the turn of the second element in the opposite direction disengages the friction engagement, for reciprocal operation to turn the shaft in unidirectional motion.
