Puzzle cube

A puzzle device, comprising eight inner shell members, first support means supporting said inner shell members for relative rotation in first groups about orthogonally related axes, a plurality of outer shell members located outwardly of and exceeding in number that of said inner shell members and second means supporting said outer shell members from said inner shell members for movement with an relative to said inner shell members for rotation in second groups about orthogonally related axes, said first support means comprising an inner core member and a plurality of mutually spaced retainer members connected to and spaced from and surrounding said core member and having inside faces lying in a spherical plane concentric with said core member and a plurality of peripherally spaced slide members underlying said retainer member inside faces and each being movable in a circular path about orthogonally related axes intersecting at the center of said spherical plane, some of said inner shell members being connected to respective ones of said slide members and disposed outwardly of said slide and retainer members, each of said inner shell members having a spherical outer face and three orthogonally related corners provided with 90 degree arcuate recesses, said shell members being relatively movable to bring groups of four of said recesses into registry to delineate six orthoganally related circular apertures, four central of said outer shell members associated with each of said circular apertures and each having a first coupling element projecting therefrom and peripherally slidably engaging the edge delineating the repective aperture, the outer edges of each of said central outer shell members having a depending outer border with an arcuate face spaced from and concentric with said inner shell members outer face to delineate orthogonally related spaced guide paths.
