  • Patent number: 5350174
    Abstract: The ball delivery system of the invention consists of a ramp located beneath the playfield where the ramp leads from an inlet accessible by the ball in play to at least one play feature to be loaded. At least one ball is stored in the ramp at each play feature such that the stored ball can be loaded into the play feature. A sensor located adjacent the inlet detects the entrance of the ball in play into the ramp and sends a signal to the game microprocessor indicating that a ball has entered the ramp. The microprocessor, upon receiving this signal, immediately loads the desired play feature with the stored ball such that the play feature can be immediately activated. The ball that entered the ramp inlet is then directed to the just activated play feature and becomes the stored ball for that play feature. Thus, the dead time associated with existing ball delivery system is eliminated.

  • Patent number: 5333866
    Abstract: A pinball machine has a plurality of ball-deflecting components mounted to a playfield section. The playfield section is selectively translated in response to player input, so that the ball is deflected by the ball-deflecting components to locations selected by the player. The translation of the playfield section, for example, is responsive to the conventional push-button switches that are operated by the player for activating flippers, and in this case the push-buttons activate respective solenoids for translating the playfield section in two different directions. The playfield section, however, could be translated in different directions along two or three orthogonal axes in response to a more complex player-input device such as a joy-stick.

  • Patent number: 5071128
    Abstract: A simulated football game having a magnetic disc rollable out of a chute onto a scrimmage field on which defense players having a piece of iron embedded therein are movably situated, a huddle being releasably retained to retain the disc in the chute. The disc is used for determining running play yardage, the disc being rollable into a defense player. A calculator wheel is rotated in only one direction by dual gears regardless of the direction of rotation of the gears and simultaneously moves a marker over a marker field to indicate the position of a football relative to the marker field. The wheel is used to ascertain yardage resulting from passing, and other type plays. A marble carrier is rotated a fraction of a complete revolution each time a plunger is depressed for indicating a play and releasing the huddle to allow a disc to roll out of the chute. The carrier in being rotated, at times, discharges a marble to roll onto the scrimmage field for indicating whether there is a penalty or a fumble.
