  • Patent number: 5664777
    Abstract: A play feature for a pinball game permits the storage of a number of game balls and release of the balls at high speed and in quick succession back onto the playfield for multiple ball play. A rotor element having a plurality of vertical vanes is disposed within a circular housing having a conical lip. The base and vanes of the rotor, together with the conical lip, define receptacles for receiving game balls. When a predetermined rotor speed is reached, the balls travel upwards on the conical lip and outward against an outer wall of the housing. The stored balls are conveyed successively to a discharge channel where they return to the play field at high speed.

  • Patent number: 5533726
    Abstract: The improved player feature of the invention comprises an arm mounted for rotation about a vertical axis. An electromagnet is attached to the arm's outer end which is capable of suspending a ferromagnetic ball. Located below and along the path traveled by the magnet are a plurality of play features such as ramps, chutes, outholes and the like. A ball elevator is provided to bring the pinball to the electromagnet. The electromagnet is rotated over the play features. When the magnet is aligned with a desired play feature, the player presses a button to deactivate the electromagnet thereby dropping the ball onto the desired feature.
