Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
96 words
A motor of the class described comprising in combination: rotatable output shaft means; permanently magnetized means mounted for rotation with said output shaft means; movable permanent magnet means operable to move periodically into a position proximate to said magnetized means so as to induce rotation about said output shaft means; solenoid means connected to said movable magnet means adapted to generate said periodic movement; and cam timing means on said output shaft means operable to activate said solenoid means at the proper intervals to achieve optimum rotation of said magnetized means and said output shaft means.
Claim 2
Dependent Claim
96 words
A motor of the class described comprising in combination: rotatable output shaft means; permanently magnetized means mounted for rotation with said output shaft means; movable permanent magnet means operable to move periodically into a position proximate to said magnetized means so as to induce rotation about said output shaft means; solenoid means connected to said movable magnet means adapted to generate said periodic movement; and cam timing means on said output shaft means operable to activate said solenoid means at the proper intervals to achieve optimum rotation of said magnetized means and said output shaft means.
Claim 3
Dependent Claim
37 words
The apparatus of claim 1 including cam timing means on said output shaft means operable to activate said solenoid means at the proper intervals to achieve optimum rotation of said magnetized means and said output shaft means.
Claim 4
Dependent Claim
34 words
The apparatus of claim 1 in which said cam timing means comprise cams on said output shaft means adapted to periodically activate switches connected to supply power to said solenoid means from a battery.
Claim 5
Dependent Claim
41 words
The apparatus of claim 3 in which said magnetized means comprises a plurality of elongated members mounted on the output shaft, each member having a magnet mounted on each end of the member at a predetermined distance from said output shaft.
Claim 6
Dependent Claim
43 words
The apparatus of claim 4 in which said movable magnet means comprises magnets mounted on pivoting members operable to periodically pivot toward said magnets on said elongated members in a repelling position so as to push the elongated members about the output shaft.
Claim 7
Dependent Claim
29 words
The apparatus of claim 5 in which said cam activated switches are pivotably mounted about said output shaft so as to permit the adjustable timing of said solenoid means.
