  • Patent number: 4129963
    Abstract: A toy article having a body formed in an egg-like configuration and including a top portion and a base in which a weight is located, the weight insuring that the body will always return to an upright position regardless of exterior forces applied thereto. A central section is disposed between the base and the top portion and is rotatable relative thereto, the central section being divided symmetrically into an opaque portion and a clear portion. Located interiorly of the central section is a fixed interior band having graphic material imprinted thereon that is visible when the clear portion of the central section is aligned therewith, wherein relative movement of the central section with respect to the interior band, locates a selected part of said graphic material in alignment with the clear portion of the central section for visual access thereto.

  • Patent number: 4101134
    Abstract: A voice or sound unit adapted for use on toys and the like has a mechanical linkage system with a joint capable of transmitting sound indicia while isolating the tone arm from any absorption of stylus movement. The tone arm can employ flexure hinges to insure a constant force on the stylus. A planetary gear coupling system provides a unique drive transmission to either a single turntable or a pair of concentric turntables. If a pair of turntables are used, they can be relatively rotated to combine a large number of sound sequences.
