A reciprocating action drive for converting reciprocating linear motion to uni-directional rotational motion is disclosed. The reciprocating action drive has a lever arm connected to a drive shaft via a first overrunning clutch such that when the lever arm is rotated in a first direction of rotation by a reciprocating linear motion, the drive shaft is rotates in the same direction. A further overrunning clutch connects the drive shaft such that the drive shaft may rotate in the first direction with respect to the frame, but not in the second, opposite direction. Such an arrangement prevents the drive shaft being driven in the second opposite, direction with respect to the frame. This prevents the lever arms being driven to interfere with any connection they may have to a source of linear reciprocating motion, thereby avoiding damage to such a connection.
