Gyroscope-monocycle
First Claim
1. A flying saucer-shaped gyroscope toy comprising:
- a circular dish-shaped rotor having a circular lower edge surrounding a first axis of rotation at its center and slits therein symmetrically disposed with respect to said first axis of rotation;
said slits causing a buzzing sound when said rotor rotates;
a lower circular dish-shaped body having a second axis of rotation aligned with said first axis of rotation, a circular upper edge having the same diameter as the diameter as said circular lower edge of said rotor and a point edge at its bottom surface along said second axis of rotation;
a d.c. motor mounted in said lower body along said second axis of rotation and having a drive shaft extending along said second axis of rotation and engageable with said rotor along said first axis of rotation for driving said rotor to rotate, said gyroscope being supported on its point edge by gyroscopic action;
means for vertically supporting said rotor and body for rotation about said first axis of rotation when said means is in a first orientation or a second orientation with respect to said body, said means being rotatable with said body in said first orientation, said body rotating in relation to said means in said second orientation;
electric light means, including a light source mounted in said body, for providing light when said rotor is rotating in response to said motor;
said electric light means including a vibrating switch for turning said light source on and off when said rotor is caused to rotate by said motor; and
a plurality of satellite bodies fixedly mounted to said lower body adjacent said upper circular edge symmetrically disposed in relation to said second axis of rotation.

Abstract
A flying saucer-shape gyroscope monocycle that stands by its own gyroscope action. The device is composed of a transparent plastic-made upper dish-rotor and a lower dish body. A small D.C. motor is installed in a central hole of the lower dish body and is powered by two small batteries. The shaft of the motor is fitted tightly with the upper rotor so as to drive the rotor. High speed rotation of the upper rotor causes slits on the surface to buzz continuously. The unbalanced force of the high speed rotating upper rotor causes the whole gyroscope to vibrate and thus a vibrating switch disposed in the lower dish body contacts intermittently to cause a bulb connected thereto to flash intermittently. The flashing is visible through the transparent upper rotor and a side window in the lower dish body. Satellite bodies disposed along a circular flange on the lower body rotate counterclockwise by the reaction to the motor driving torque.
