Abstract
A compound nutational carriage mechanism for a game, ambulatory toy or the like including a first disc member having a curvilinear periphery and a second disc member having a similar curvilinear periphery. The disc members are operably connected in such a manner that planar extensions of the disc members mutually intersect and form an angular relationship therebetween and the line of intersection of the planes extends perpendicular to a third plane. An axle is connected to the first and second disc members and lies in alignment with the line of intersection of the planar extentions of the first and second disc members.
