Abstract
Abstract A centrifugal thrust motor for vehicles or the like including a frame member having a continuous track portion and a rotating shiftable shaft positioned within said track portion; at least two weight support members each having a working length secured to the shaft, and a drive mechanism provided for rotating the shaft in a direction transverse to the axis of the shaft, whereby when the shaft is rotating, upon shifting the shaft, the working length of the remainder of the weight support members in at least one point of the rotation of the weights, so as to move a vehicle or the like by providing a thrust in a direction transverse to the shaft, with appropriate braking for the opposite thrust of the weights.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
158 words
A centrifugal thrust motor including: a. a frame member having a continuous track portion, b. a rotating, shiftable shaft within said track portion, c. at least two weight support members, each having a working length, d. means for connecting said weight support members to said shaft, e. substantially equal weight means attached to one end of each of said weight support members, said weight means being in engagement with said track, f. at least two of said weight means being on opposite sides of said shaft, g. means for rotating said shaft, h. means for shifting said shaft in a direction transverse to the axis of said shaft, i. whereby when said shaft is rotating, upon shifting said shaft, the working length of at least one of said weight support members is greater than the other individual working lengths of the remainder of said weight support members in at least one point of the rotation of said weights.
Claim 2
Dependent Claim
158 words
A centrifugal thrust motor including: a. a frame member having a continuous track portion, b. a rotating, shiftable shaft within said track portion, c. at least two weight support members, each having a working length, d. means for connecting said weight support members to said shaft, e. substantially equal weight means attached to one end of each of said weight support members, said weight means being in engagement with said track, f. at least two of said weight means being on opposite sides of said shaft, g. means for rotating said shaft, h. means for shifting said shaft in a direction transverse to the axis of said shaft, i. whereby when said shaft is rotating, upon shifting said shaft, the working length of at least one of said weight support members is greater than the other individual working lengths of the remainder of said weight support members in at least one point of the rotation of said weights.
Claim 3
Dependent Claim
25 words
A centrifugal thrust motor as in claim 1 and wherein: a. said means for shifting said shaft includes hydRaulic cylinders mounted on said frame member.
Claim 4
Dependent Claim
