  • Patent number: 5388723
    Abstract: A device for randomly dispensing one of a plurality of discrete random members. The device includes a housing having a cavity within which the random members may be contained. The housing is supported by a pair of supporting actuators which cooperate to open an aperture in the cavity when the housing is downwardly pushed by a user. A random member is thereby allowed to escape from the housing for generating random numbers such as utilized in bingo, lotteries, and other games. Preferably, the housing is shaped as an animal, such as a chicken, turkey, or the like.
