Abstract
This invention pertains to a generally ball shaped device having a hollow interior chamber with a relatively small weight such as a steel ball bearing in said chamber; the exterior surface of the device is provided with a plurality of numbers or other symbals spaced thereabout, preferably in a symmetrical relationship. The interior chamber provides a pocket diametrically opposite to each symbol whereby the ball shaped object, when thrown along any flat surface or into water, will always come to rest with one symbol positioned on the top thereof diametrically opposite to the pocket in which the interior weight settles due to gravity forces.
Claims1
A symbol indicating device comprising a generally ball shaped object formed of two halves fixed together by a suitable adhesive means and providing a plurality of symbols disposed about the exterior surface thereof, a hollow, chamber defining interior and a pocket in said interior chamber diametrically opposite each of said symbols, and weight means freely disposed in said interior chamber to settle in any one of said pockets, when said ball shaped object comes to rest after movement thereof, to move said one pocket to the bottom of said chamber by gravity forces, thereby positioning the diametrically opposite symbol atop said exterior surface, said plurality of symbols being disposed in a single circumferential line about said exterior suface, said hollow, interior chamber being provided with a pair of spaced apart, opposed, inwardly convex discs, each fixed by a suitable adhesive to said interior to define a circumferential chamber therebetween corresponding to said single circumferential line, said weight means being freely disposed in said circumferential chamber.
