Abstract
A top spindle designed especially for use in connection with parts of a construction toy set, to enable the assembly of spinning tops having a wide variety of inertia members. The spindle includes a main stem provided with an integral support platform. A symmetrically arranged pair of drive lugs project upwardly from the support platform. The stem includes a locating and gripping hub adjacent to the platform and adapted to receive and tightly grip the central hub opening of a construction part from the construction toy set, such parts being in the form of wheels, pulleys, gears or connector elements. Such construction parts are pressed onto the retaining hub, after being positioned such that the upwardly projecting drive lugs engage drive openings in the construction part. Where the construction part is a connector element, that element may form a structural nucleus for the assembly of inertia elements of various sizes and shapes limited only by the imagination of the builder and the requirement that the inertia element be symmetrically balanced about the axis of the spindle.
