ABSTRACT:
A power take-off mechanism which converts rotational motion to a variety of available rotating, reciprocating and/or oscillating motions. The device comprises a rocking frame within which is mounted a rotating shaft on which is mounted an unbalanced weight. One end of the shaft is connected through a constant velocity type joint to a power source and the opposite end of the shaft rotates within a restraining ring or area on the frame. The rotating unbalanced weight transmits force through the shaft to the rocking frame which is free to pivot or move rotationally about one axis and at the same time to reciprocate axially along the same axis. Power may be taken off from various points on the frame as either reciprocating motion, reciprocating motion with a cyclicly reversing twist, circular motion inscribed on a plane of rotation, or eliptical motion inscribed on a plane of rotation.
