Abstract
Abstract A gyroscopic propulsion device includes a rotatable body in which the center of mass of the rotating body is offset away from a first axis to a second axis. The body rotating around the eccentric second axis of the rotating body generates a propulsion force which moves a vehicle to which the device is attached. In preferred embodiments, the body includes a rotating flywheel or a planar system of spokes along which weights oscillate on springs.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
97 words
A gyroscopic propulsion device, comprising: a vehicle having means for supporting the same on a surface; a rotatable body mounted on the vehicle; rotating means for establishing a first substantially horizontal axis of rotation for rotating the body; and offsetting means comprising resilient elements which allow said body to initially offset by the effect of gravity and for offsetting said body by the force evoked by its rotation to a second axis of rotation, about which the body rotates, vertically and horizontally away from and substantially parallel to the first axis of rotation for propelling the vehicle.
Claim 2
Dependent Claim
97 words
A gyroscopic propulsion device, comprising: a vehicle having means for supporting the same on a surface; a rotatable body mounted on the vehicle; rotating means for establishing a first substantially horizontal axis of rotation for rotating the body; and offsetting means comprising resilient elements which allow said body to initially offset by the effect of gravity and for offsetting said body by the force evoked by its rotation to a second axis of rotation, about which the body rotates, vertically and horizontally away from and substantially parallel to the first axis of rotation for propelling the vehicle.
Claim 3
Dependent Claim
23 words
The propulsion device of claim 1 wherein the offsetting means further comprises a means for offsetting the center of mass of the body.
Claim 4
Dependent Claim
27 words
The propulsion device of claim 1 wherein the body includes a plane of rotation, and the offsetting means includes means for displacing the body in the plane.
Claim 5
Dependent Claim
36 words
The propulsion device of claim 1 wherein the rotatable body comprises a hub connected to a flywheel with flexible spoke means for allowing the geometric center of the flywheel to be offset relative to the hub.
Claim 6
Dependent Claim
31 words
The propulsion device of claim 4 wherein the flexible spoke means comprises tubular spokes extending partially from the hub to the flywheel, and springs extending between the spokes and the flywheel.
Claim 7
Dependent Claim
42 words
The propulsion device of claim 5 wherein the flywheel is mounted in a vertical plane and the springs have a frequency which permits the flywheel to remain offset substantialy downwardly at the rotational frequency at which the rotating means rotates the flywheel.
Claim 8
Dependent Claim
28 words
The propulsion device of claim 1 wherein the rotating means comprises an axle fixed to the rotatable body coincident with the first axis and driven by a motor.
Claim 9
Dependent Claim
22 words
The propulsion device of claim 6 wherein the rotating means comprises an axle fixed to the hub and driven by a motor.
Claim 10
Dependent Claim
16 words
The propulsion device of claim 6 further comprising means for changing the frequency of the springs.
Claim 11
Dependent Claim
119 words
A gyroscopic propulsion device, comprising: a vehicle having means for supporting the same on a surface; a rotatable body mounted on the vehicle; rotating means for establishing a first axis of rotation for rotating the body; and propulsion means comprising resilient elements which allow said body to initially offset by the effect of gravity and for permitting said body as it rotates to offset to a second axis of rotation by the forces evoked by its rotation vertically and horizontally away from and parallel to said first axis thereby increasing the rotational impulse of the point of the rotating body which is farther away from the first axis than any other point on the body to propel the vehicle.
Claim 12
Dependent Claim
119 words
A gyroscopic propulsion device, comprising: a vehicle having means for supporting the same on a surface; a rotatable body mounted on the vehicle; rotating means for establishing a first axis of rotation for rotating the body; and propulsion means comprising resilient elements which allow said body to initially offset by the effect of gravity and for permitting said body as it rotates to offset to a second axis of rotation by the forces evoked by its rotation vertically and horizontally away from and parallel to said first axis thereby increasing the rotational impulse of the point of the rotating body which is farther away from the first axis than any other point on the body to propel the vehicle.
Claim 13
Dependent Claim
40 words
The propulsion device of claim 10 wherein the propulsion means comprises an offsetting means for offsetting the geometric center of the body to a second axis, about which the body rotates, away from and substantially parallel to the first axis.
Claim 14
Dependent Claim
41 words
The propulsion device of claim 10 wherein the propulsion means comprises an offsetting means for offsetting the center of mass of the body to a second axis, about which the body rotates, away from and substantially parallel to the first axis.
