For transferring a rotary drive to a movable member in order that the latter may be reciprocated with a variable amplitude stroke, a mechanism is disclosed which comprises two parallel shafts each, carrying an arm or a disc, a peripheral pin on each disc being pivoted to one end of a connecting rod the opposite end of which is pivoted to the either end of a rocker. The central pivot of the rocker is borne by a member which is so guided that only a reciprocal motion is permitted thereto.
