Spinning toy

Abstract

Abstract This invention is a toy in which two principal assemblies of parts are made to counter-rotate by a concentric internal coil spring, previously wound up by hand, whose tension is maintained by a one-way clutch and is released when the weight of the toy, when it is placed on a flat surface, disengages the clutch. A carrying handle, in the form of a miniature fence of posts and railings, is attached to the upper assembly. A mechanism is incorporated to free the inner end of the spring from its arbor when the energy of the spring is spent, so that the assemblies may continue to counter-rotate by inertia without damage to the spring. The toy is equipped with a lighting system of flashing light-bulbs around the perimeter and in a central transparent cupola, supplied with energy from flashlight-type electrical batteries in a central tubular shaft through a switch on the upper assembly. A tricycle supporting gear supports and stabilizes the toy when in operation, consisting of three hollow spheres on radial axles in the base, or of three hollow hemispheres on the lower face of an annular plate attached to the base of the lower assembly. All parts except light bulbs, batteries, wiring, contact parts, switch, and parts necessarily made of metal such as springs, axles, a ring carrying a hook to engage the inner end of the driving spring, and bolts for assembly, may be made of impact-resistant synthetic insulating plastic material by injection-molding or other appropriate process. External parts are covered with paint to resemble glittering metal, and illumination holes in the rim of the upper assembly are covered with thin tinted transparent plastic film.
