Abstract: A transmission includes an input coupled to reciprocate a lug along a stroke path. The lug is coupled between a shuttle and a persuader, the shuttle is coupled to drive an output in response to reciprocation of the shuttle along a drive path, and the persuader is coupled between the lug and the shuttle and is operable to change the stroke path between an inoperative direction relative to the drive path isolating the shuttle from the forcible reciprocation of the lug and an operative direction relative to the drive path transferring the forcible reciprocation of the lug along the stroke path to the shuttle imparting reciprocation to the shuttle along the drive path. Forcible reciprocation of the lug is transferred to the shuttle along an infinitely variable gearing range between the inoperative and operative directions of the stroke path of the lug relative to the drive path of the shuttle.
