Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
70 words
A drive system comprising: stationary support means; a rotatable shaft coaxial with said support means; a rotatable motor support means rigidly affixed to said shaft; at least two pair of electric motors equally spaced about the periphery of said motor support means; means drivingly coupling the output shaft of each of said motors to said stationary support means; and means for intermittently supplying oppositely disposed electric motors with electric current.
Claim 2
Dependent Claim
70 words
A drive system comprising: stationary support means; a rotatable shaft coaxial with said support means; a rotatable motor support means rigidly affixed to said shaft; at least two pair of electric motors equally spaced about the periphery of said motor support means; means drivingly coupling the output shaft of each of said motors to said stationary support means; and means for intermittently supplying oppositely disposed electric motors with electric current.
Claim 3
Dependent Claim
29 words
A drive system as described in claim 1 wherein the stationary support means comprises: a casing; and a ring gear rigidly mounted on the upper portion of the casing.
Claim 4
Dependent Claim
34 words
A drive system as described in claim 1 wherein the electric motors are direct current machines mounted on the motor support means with the output shaft of each motor parallel to the rotatable shaft.
Claim 5
Dependent Claim
41 words
A drive system as described in claim 2 wherein the means drivingly coupling said output shaft of each electric motor to said ring gear comprises; gear means mounted on said motor output shafts, said gear means engaging said ring gear. 5.
Claim 6
Dependent Claim
90 words
A drive system as described in claim 1 wherein said means for intermittently supplying oppositely disposed electric motors with electric current comprises: segmented commutator means rigidly mounted on the motor support means; a pair of opposed brushes slidably mounted adjacent to the commutator means; means for positioning said brushes in contact with said commutator means; means for supplying electric current to said brushes; and means connected between individual segments of said commutator means and individual motors for transmitting electric current from each segment of said commutator to a corresponding motor.
Claim 7
Dependent Claim
90 words
A drive system as described in claim 4 wherein said means for intermittently supplying oppositely disposed electric motors with electric current comprises: segmented commutator means rigidly mounted on the motor support means; a pair of opposed brushes slidably mounted adjacent to the commutator means; means for positioning said brushes in contact with said commutator means; means for supplying electric current to said brushes; and means connected between individual segments of said commutator means and individual motors for transmitting electric current from each segment of said commutator to a corresponding motor.
Claim 8
Dependent Claim
34 words
A drive system as described in claim 6 wherein the electric motors are direct current machines mounted on the motor support means with the output shaft of each motor parallel to the rotatable shaft.
