ABSTRACT:
A toy having combined rotational motion about a horizontal axis and a translational motion in a vertical direction. Three parallel discs are connected through their centers by a single axle. An inner disc is positioned between two outside discs leaving a gap on the axle between the inner disc and each of the outside discs. Opposite ends of a single string are attached to the axle at each of the gaps and the string is looped over a rotatably-mounted pulley. The pulley is held by a support member connected to a swivel system which is in turn connected to a ring. In order to operate the toy the user's finger is placed in the ring and an up-and-down motion is initiated. The balance of the toy during operation is facilitated by the use of a single string connected to the axle at two points, said string being looped over a support in a slidable manner.
