Abstract
Apparatus comprising a support structure having first and second members rotatably mounted on the support structure and drive apparatus for rotating the first and second members so that the second member rotates in a direction opposite to the direction of rotation of the first member. A movable member for performing work is mounted on the support structure for reciprocating linear movement and is connected to the first and second members so that rotation of the first and second members reciprocates the movable member. In one embodiment, the movable member does not rotate during the reciprocation thereof but in another embodiment the movable member rotates during the reciprocation thereof.
