Abstract
Abstract A permanent magnet motor which utilizes pairs of permanent magnets as the power source for the motor. The magnets of each pair are arranged with their like poles adjacent one another so that normally the magnets of the pairs oppose or repel one another. Shiftable means are provided for being inserted between the magnets of each pair so as to then to alter the magnetic field between the magnets to cause the magnets to move toward one another with considerable force. One magnet of each pair is connected to a common drive shaft member. The shiftable means for being inserted between and withdrawn from the magnets of each pair are shifted by any suitable means in timed relationship with one another.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
114 words
A dynamo-electro, permanent magnet motor comprising pairs of permanent magnets, one magnet of each pair being stationary and the other magnet of each pair being shiftable relative thereto, the magnets of each pair being arranged with their like poles adjacent one another to thereby normally place them in a repulse state, shiftable magnetic plate means, and means for shifting said plate means from a position withdrawn from between the magnets of each pair to a position directly between the magnets of each pair thereby, respectively, causing the magnets of each pair to repulse each other and then move toward each other, means connecting the shiftable magnets of each pair to a common drive shaft.
Claim 2
Dependent Claim
114 words
A dynamo-electro, permanent magnet motor comprising pairs of permanent magnets, one magnet of each pair being stationary and the other magnet of each pair being shiftable relative thereto, the magnets of each pair being arranged with their like poles adjacent one another to thereby normally place them in a repulse state, shiftable magnetic plate means, and means for shifting said plate means from a position withdrawn from between the magnets of each pair to a position directly between the magnets of each pair thereby, respectively, causing the magnets of each pair to repulse each other and then move toward each other, means connecting the shiftable magnets of each pair to a common drive shaft.
Claim 3
Dependent Claim
114 words
A dynamo-electro, permanent magnet motor comprising pairs of permanent magnets, one magnet of each pair being stationary and the other magnet of each pair being shiftable relative thereto, the magnets of each pair being arranged with their like poles adjacent one another to thereby normally place them in a repulse state, shiftable magnetic plate means, and means for shifting said plate means from a position withdrawn from between the magnets of each pair to a position directly between the magnets of each pair thereby, respectively, causing the magnets of each pair to repulse each other and then move toward each other, means connecting the shiftable magnets of each pair to a common drive shaft.
Claim 4
Dependent Claim
114 words
A dynamo-electro, permanent magnet motor comprising pairs of permanent magnets, one magnet of each pair being stationary and the other magnet of each pair being shiftable relative thereto, the magnets of each pair being arranged with their like poles adjacent one another to thereby normally place them in a repulse state, shiftable magnetic plate means, and means for shifting said plate means from a position withdrawn from between the magnets of each pair to a position directly between the magnets of each pair thereby, respectively, causing the magnets of each pair to repulse each other and then move toward each other, means connecting the shiftable magnets of each pair to a common drive shaft.
Claim 5
Dependent Claim
51 words
The motor set forth in claim 1 further characterized in that said means for shifting said plate means comprises electrical solenoid means attached to said plate means, and a distributor rotor for alternately energizing and deenergizing said solenoid means whereby said plate means are shifted in timed relationship with one another.
Claim 6
Dependent Claim
26 words
The motor set forth in claim 1 further characterized in that anti-friction means are provided for shifting and guiding said plate means in their shifting movement.
Claim 7
Dependent Claim
30 words
The motor set forth in claim 1 wherein said shiftable magnets are movable in a reciprocating movement, and crankshafts connect each of said shiftable magnets to a common drive shaft.
Claim 8
Dependent Claim
28 words
The motor set forth in claim 1 further characterized in that said shiftable magnets are all connected to a common rotor for rotary movement together as a unit.
