  • Patent number: 5415402
    Abstract: The magnetic ball-walker of the invention comprises an L-shaped arm which rotates in a plane perpendicular to the playfield for transporting a pinball between first and second playfield surfaces. The arm carries an electromagnet on one end and a counterweight on the other, the counterweight maintaining the arm in a ball receiving position. In this position, a ferromagnetic ball received from the first surface can be captured by the electromagnet if energized. The momentum of the rolling ball causes the arm to rotate to a ball discharge position so that the ball can be discharged onto the second surface by deenergizing the electromagnet.

  • Patent number: 5383663
    Abstract: The play feature consists of a first surface and second surface for supporting a rolling ball therebetween. The surfaces are made movable relative to one another such that in a first position they support a ball therebetween and in a second position they are spaced far enough apart to allow a ball to fall therebetween. The surfaces are movable relative to one another by a solenoid or other similar driver where the solenoid is controlled by a player operated button. As a ball rides along the first and second surfaces, the player operates the solenoid to move the first and second surfaces apart allowing the ball to fall between the surfaces at a desired location. A plurality of targets, ramps or the like can be provided below the surfaces as target objectives for the player.

  • Patent number: 5358243
    Abstract: The ball trough is of a unitary construction such that it is mounted directly to the underside of the playfield as a single piece. The ball trough consists of a generally U-shaped channel that is mounted to the underside of the playfield and extends between the drain hole and the shooter lane. The bottom surface of the channel is inclined relative to the horizontal such that a ball entering at the drain hole will roll under the force of gravity toward the shooter lane. When activated, the solenoid plunger will kick the ball located adjacent the shooter lane up through an aperture in the playfield and into the shooter lane. A series of optical switches are mounted on the channel and arranged such that each switch will detect the presence or absence of the ball in the queue.

  • Patent number: 5358241
    Abstract: The ramp consists of a wire rail formed as a helix. The rail extends between a first elevation where the ball enters the ramp to a second, lower elevation where the ball exits the ramp. A straight rail extends through the center of the helical rail for the length thereof. The helical rail is dimensioned such that the distance between it and straight rail is less than the diameter of the ball. As a result, the ball will contact both the straight rail and helical rail simultaneously as it rolls down the helical rail by the force of gravity.

  • 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: 5338031
    Abstract: The tilt switch/incline indicator of the invention consists of a first support member that is connected to the game cabinet in a known orientation. A second member is pivotably supported on the first member and can be fixed relative thereto at angles corresponding to the desired angle of incline of the playfield. The second member supports a pendulum-type tilt switch similar to that used in the prior art. The pendulum acts like a plumb line to give a visual indication to the game operator that the playfield is at the desired angle set at the second member by observing when the pendulum is centered relative to the contact. The mechanism of the invention uses the tilt switch as the level indicator such that the playfield can be positioned at a known angle without requiring a separate level indicator or the recalibration to the tilt switch.
