1. In a motion transformer for converting oscillatory to rotary motion comprising a ratchet wheel mounted both for oscillatory back-and-forth motion substantially on a diameter thereof and for rotary motion substantially about its center, a pair of stops fixedly mounted for limiting the amplitude of said oscillatory motion, and a pair of pawls engaging the teeth of said ratchet wheel substantially at the ends of a wheel diameter approximately normal to the direction of said oscillatory motion, the improvement comprising a resilient shock-absorbing braking member secured to each of said stops in position to abut the teeth of said ratchet wheel as it approaches each end of its oscillatory path of travel, whereby the motion of the ratchet wheel at each end of its oscillatory path of travel is gently braked to a stop without injury to the teeth.
