(Cl. ‘i6-1,) l Our invention relates toa roly poly, that is, 2 head portion 4 connected tothe body portion by to a device which may be rocked or tilted from means of a neck portion 5. The device is adapted a vertical position on a supporting surface, and which upon being freed' from external influence, to `stand upon `a supporting surface, and. thev lower half of the spherical body portion 3 provides a s'emispherical base portion upon which the will right itself~ The center of gravity ofthe de vice is so oriented that the body tends always to return to a true vertical position. A roly poly device of the sort to which the invention is more particularly directed consists in a hollow body having, and being adapted to stand on, a substantially semispherical bottom. Within the body a weight or mass is concentrated to provide a center of gravity so located that the body is in stable equilibrium as long asf it device may be Icaused to rock or roll on said supporting surface. Within the hollow body of this semispherical base portion a weight element 6 is secured, thereby giving the device a center of gravity which is eñective normally to sustain the supported vdevice in the upright position in which it is shown in Figure 1. ~ In accordance with the invention the body of the device-is formed oi a plurality of hollow shell stands in righted position. .
