Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
128 words
Power take-off apparatus, comprising: a frame having an opening therethrough, means supporting said frame for oscillatory and axial movement relative to an axis, a shaft rotatably mounted on said frame and having a free end extending through said opening in spaced relation to at least a portion of the surrounding frame surface defining said openings, a weight mounted in off-center relation of said shaft, means for rotating said shaft and said weight thereon to cause the free end of said shaft to move along the frame surface defining said opeinig to effect oscillation and axial movement of said frame relative to said axis, and means mounted on said frame to enable power to be taken off said frame at different points thereon which generate different power output motions.
Claim 2
Dependent Claim
128 words
Power take-off apparatus, comprising: a frame having an opening therethrough, means supporting said frame for oscillatory and axial movement relative to an axis, a shaft rotatably mounted on said frame and having a free end extending through said opening in spaced relation to at least a portion of the surrounding frame surface defining said openings, a weight mounted in off-center relation of said shaft, means for rotating said shaft and said weight thereon to cause the free end of said shaft to move along the frame surface defining said opeinig to effect oscillation and axial movement of said frame relative to said axis, and means mounted on said frame to enable power to be taken off said frame at different points thereon which generate different power output motions.
Claim 3
Dependent Claim
49 words
The apparatus of claim 1 wherein said frame comprises a pair of depending posts connected at the upper end thereof by a cross piece having said opening therein, and said supporting means comprises a rotatable and axially movable axle member connected to said posts at the lower portion thereof.
Claim 4
Dependent Claim
30 words
The apparatus of claim 2 wherein said rotating means comprises a motor mounted on said frame, and wherein said motor is connected to said shaft by a constant velocity joint.
Claim 5
Dependent Claim
55 words
The apparatus of claim 2 wherein the longitudinal axis of said axle member is substantially horizontal, and said shaft is disposed in an upright position in substantially perpendicular relation to said axle member, the lower end of said shaft being connected to said motor and the upper end of said shaft extending through said openings.
Claim 6
Dependent Claim
22 words
The apparatus of claim 4 wherein a collar is adjustably mounted on said shaft, and said weight is mounted on said collar.
Claim 7
Dependent Claim
23 words
The apparatus of claim 5 wherein spring means engage one of said frame posts to normally maintain said posts in an upright position.
Claim 8
Dependent Claim
17 words
The apparatus of claim 6 wherein a power take-off point is secured to one of said posts.
Claim 9
Dependent Claim
16 words
The apparatus of claim 6 wherein a power take-off point is secured to said axle member.
Claim 10
Dependent Claim
28 words
The apparatus of claim 6 wherein a cross bar is connected to said posts near the lower portion thereof, and said motor is secured to said cross bar.
Claim 11
Dependent Claim
18 words
The apparatus of claim 6 wherein said opening is defined by a member secured to said cross piece.
