ABSTRACT:
A gyroscopic rotor has a shaft with opposite ends rotatably supported in a housing on a first or spin axis and capable of rotating around the housing at right angles to the spin axis, comprising a second axis. The support of the shaft in the housing is a circular track concentric with the second axis and positioned on opposite sides of and adjacent the ends of the shaft for rolling contact by end portions of the shaft when a torque is applied to the housing about a third axis at right angles to both the spin and second axis whereby to cause precession of the shaft and rotor about the second axis. The track comprises a circumferential groove with opposed surfaces of a type having a friction engagement with the end of the shaft to provide an improved rolling precessional movement of the shaft and rotor. A ring is supported in the circumferential groove and has notches receiving end portions of the shaft for establishing a drive connection between the shaft and the guide ring. This guide ring has free sliding movement against the opposed surfaces of the groove. The housing is formed of a pair of sections which permit access to the track for repair and maintenance. The device includes electrical generating portions capable of supplying power to visual and/or audio devices forming a part of the housing.
