Abstract
Abstract Apparatus for dual random number selection is provided to pick numbers in a lottery or the like. Said invention consists of a base having a mixing reservoir, a well and a conduit between the mixing reservoir and the well, a plurality of filler and winning balls contained in the mixing reservoir, a wheel with a plurality of receptacles on its circumference each randomly numbered contained in the wall, a transparent cover over the base with the wheel's shaft through it connected to a knob to allow the wheel to rotate with each receptacle able to pick up one ball at random when placed in a vertical position.

Claim 1
Independent Claim
240 words
Apparatus for dual random number selection which comprises: (a) a base having a mixing reservoir, a well having a central aperture and a conduit between said mixing chamber and said well; (b) a plurality of colored filler balls stationed in said mixing reservoir in said base; (c) a plurality of different colored winning balls stationed in said mixing reservoir in said base; (d) a wheel assembly having a wheel with a plurality of receptacles on its circumference each of which are randomly numbered on the top surface of said wheel, a lower shaft affixed to the bottom central surface of said wheel that mates with said central aperture in said well of said base whereby said receptacles are level with said conduit of said base and an upper shaft affixed to the top central surface of said wheel; (e) a transparent cover affixed to said base having an aperture that allows said upper shaft of said wheel assembly to extend above top surface of said cover; and (f) a knob having an aperture in the bottom surface that mates with said upper shaft of said wheel assembly whereby said wheel is free to rotate clockwise or counterclockwise between said base and said cover so each said receptacle is able to receive one said filler ball or said winning ball that travels from said mixing chamber into said conduit in said base when said apparatus is placed in a vertical position.
