  • Patent number: 5326103
    Abstract: In an amusement device, for example a pinball game, a rotatable turntable may be provided. A cover has a position for enclosing and retaining a ball rolling on the turntable. A shaft is also provided for raising the cover from that position, to permit the ball to roll outwardly across the periphery of the turntable to another portion of the device. This provides significant variation in the play of the amusement device in that the ball can leave the turntable in any horizontal direction to provide great variation in play of the ball.

  • Patent number: 5322282
    Abstract: A rotatable member is provided for a rolling ball amusement device. The rotatable member defines a ball receiving aperture which is positioned to receive a rolling ball and to cause transfer of kinetic energy from the ball to the rotatable member, to cause the member to rotate to one of a plurality of discrete, temporarily locked rotating positions, with the selection of the particular rotating position depending on the amount of kinetic energy so transferred. Preferably, switches are provided for identifying to the electronic controls of the amusement device the discrete rotating position occupied by the rotatable member. Upon command, the temporary lock of the rotating positions may be released. A spring or the like then rotates the member back to an original, ball-receiving position upon such release, which propels the ball back onto the playfield with a velocity that depends on the particular discrete rotating position achieved.

  • Patent number: 5002279
    Abstract: A pinball machine defines a play field to receive a rolling ball for pinball play. By this invention, a ball-aperture carries a first ball, a second ball rolling on the play field toward the aperture is prevented from entering the aperture and is deflected away from the aperture in a first direction by collision with the first ball in the aperture. Means are provided for displacing balls from the aperture and causing them to roll on the play field in a direction other than the first direction. Thus, by the improvement of this invention, balls directed at the aperture are sent away therefrom in two different directions, for different play patterns on the play field.

  • Patent number: 4968031
    Abstract: A pinball machine having a first ramp on a play field. The first ramp is positioned so that pinballs may be propelled up the ramp to fly through space before landing again on the play field. Preferably, a second ramp is positioned on the play field to receive at least some of the flying balls launched up the first ramp.
