ABSTRACT:
A string-supported device capable of simultaneous rotation about its own axis, translational motion and orbital motion. An axle consisting of two segments, both axle-segments connected together, either directly or indirectly, and each axle-segment capable of rotating independently of the other axle-segment. Two discs are connected through their centers to each of the two axle-segments. Opposite ends of a single string are connected to each axle-segment, and the string is looped over a support member upon which it can readily slide. The support member is connected to a swivel system which is in turn connected to a ring. In order to operate the device the string is first wrapped in opposite directions around each axle-segment, and the body of the yo-yo is allowed to fall while the operator is holding the ring. An up-and-down motion of the yo-yo device is thus initiated. The two halves of the device rotate in opposite directions, thus leading to an automatic compensation of gyroscopic precession, and an avoidance of the common problems which plague the conventional yo-yo and prior modifications thereof.
