Abstract
Abstract A means for imparting rotational movement to a drive shaft comprising a support frame having the drive shaft rotatably mounted thereon. A plurality of magnet supports are secured to the drive shaft in a spaced apart and staggered relationship. Each of the supports has a plurality of radially spaced permanent magnets operatively secured thereto with each of the magnets having a positive pole on one side thereof and a negative pole on the other side thereof. A plurality of air-core solenoids are mounted on the support frame in a spaced apart relationship and are positioned relative to the support frame so that the permanent magnets on one of the supports will rotate past one of the solenoids in close proximity thereto. A distributor means is operatively mechanically connected to the drive shaft so that rotation of the drive shaft will cause the distributor means to be actuated. The distributor is electrically connected to a source of electrical energy. The distributor is also electrically connected to the solenoids so that actuation of one of the solenoids will cause the flux emanating from one side of the core of the solenoid to repel one of the magnets on one of the supports and so that the flux emanating from the other side of the core of the said solenoid will attract one of the magnets on the support to impart rotational movement to the drive shaft. The method of utilizing magnetism to achieve continuous rotation of the drive shaft is also disclosed and generally involves the repelling and attracting forces of the three-poled magnetic field which acts upon a mechanical apparatus to produce a continuous reaction from the mechanical apparatus.

Claim 1
Independent Claim
274 words
A device of the class described, comprising, a support means, a drive shaft rotatably mounted on said support means, a plurality of magnet supports secured to said drive shaft in a spaced-apart and staggered relationship, each of said supports having a plurality of radially spaced permanent magnets operatively secured thereto, each of said magnets having a positive pole on one side thereof and a negative pole on the other side thereof, the magnetic north-south polar axis of each magnet aligned substantially radially to said drive shaft axis, a plurality of air-core solenoids mounted on said support means in a spaced-apart relationship and being positioned relative to said supports whereby the permanent magnets on one of said supports will rotate past one of said solenoids in close proximity thereto, said solenoids being disposed longitudinally with respect to the longitudinal axis of said shaft, said staggered relationship of said supports causing the permanent magnets on supports to be radially offset with respect to each other, a distributor means operatively mechanically connected to said drive shaft whereby rotation of said drive shaft will cause said distributor means to be actuated, means electrically connecting said distributor means to a source of electrical energy, and means electrically connecting said distributor means with said solenoids whereby the actuation of one of said solenoids will cause the flux emanating from one side of the core of the solenoid to repel one of said magnets on said one support and whereby the flux emanating from the other side of the core of said solenoid will simultaneously attract one of said magnets on said one support to impart rotation to said drive shaft.
Claim 2
Independent Claim
274 words
A device of the class described, comprising, a support means, a drive shaft rotatably mounted on said support means, a plurality of magnet supports secured to said drive shaft in a spaced-apart and staggered relationship, each of said supports having a plurality of radially spaced permanent magnets operatively secured thereto, each of said magnets having a positive pole on one side thereof and a negative pole on the other side thereof, the magnetic north-south polar axis of each magnet aligned substantially radially to said drive shaft axis, a plurality of air-core solenoids mounted on said support means in a spaced-apart relationship and being positioned relative to said supports whereby the permanent magnets on one of said supports will rotate past one of said solenoids in close proximity thereto, said solenoids being disposed longitudinally with respect to the longitudinal axis of said shaft, said staggered relationship of said supports causing the permanent magnets on supports to be radially offset with respect to each other, a distributor means operatively mechanically connected to said drive shaft whereby rotation of said drive shaft will cause said distributor means to be actuated, means electrically connecting said distributor means to a source of electrical energy, and means electrically connecting said distributor means with said solenoids whereby the actuation of one of said solenoids will cause the flux emanating from one side of the core of the solenoid to repel one of said magnets on said one support and whereby the flux emanating from the other side of the core of said solenoid will simultaneously attract one of said magnets on said one support to impart rotation to said drive shaft.
Claim 3
Independent Claim
145 words
The method of imparting rotational movement to a drive shaft, comprising the following steps: providing a rotatable drive shaft having a plurality of spaced-apart hubs mounted thereon, each of said hubs having a plurality of radially spaced permanent magnets provided thereon having a negative pole on one side thereof and a positive pole on the other side thereof, radially offsetting the magnets on each of said hubs with respect to each other, providing a plurality of electrically operated air-core solenoids, positioning said solenoids so that the magnets on one said hubs will rotate thereby in close proximity thereto, energizing each of said solenoids in a predetermined sequence and at a predetermined time whereby the solenoid so energized will repel one of said magnets on the associated hub and will simultaneously attract the adjacent magnet on the associated hub to cause the rotation of said shaft.
Claim 4
Independent Claim
145 words
The method of imparting rotational movement to a drive shaft, comprising the following steps: providing a rotatable drive shaft having a plurality of spaced-apart hubs mounted thereon, each of said hubs having a plurality of radially spaced permanent magnets provided thereon having a negative pole on one side thereof and a positive pole on the other side thereof, radially offsetting the magnets on each of said hubs with respect to each other, providing a plurality of electrically operated air-core solenoids, positioning said solenoids so that the magnets on one said hubs will rotate thereby in close proximity thereto, energizing each of said solenoids in a predetermined sequence and at a predetermined time whereby the solenoid so energized will repel one of said magnets on the associated hub and will simultaneously attract the adjacent magnet on the associated hub to cause the rotation of said shaft.
Claim 5
Dependent Claim
13 words
The method of claim 2 wherein direct current is supplied to said solenoids.
Claim 6
Dependent Claim
65 words
The method of claim 2 wherein a distributor means is provided which is mechanically connected to said drive shaft, the method also comprising the step of electrically connecting the distributor means to said solenoids so that actuation of said distributor means by said drive shaft causes pulses of electrical energy to be supplied to said solenoids in said predetermined sequence and at said predetermined time.
