Abstract: A lottery apparatus comprising a receptacle from which lottery balls can pass into a mixing chamber. A screw conveyor in the form of a rotatable tube with an internal helical baffle extends horizontally from the mixing chamber to a discharge chamber. The end of the screw conveyor in the mixing chamber has a scoop attached thereto which serves to agitate the lottery balls in the mixing chamber and to feed one ball to the conveyor with each rotation of the conveyor. The rotatable tube is transparent so that progress of each lottery ball therethrough can be watched. Clear plastics are preferred materials for most apparatus parts. A manual crank or an electric motor is used to rotate the screw conveyor.
