  • Patent number: 5899454
    Abstract: A ramp with an integral ball deflector is positioned upon the playfield of a pinball game with its entrance approximately level with the playfield. A ball deflector having the shape of a triangle is mounted upon the bottom of the ramp with its widest portion near to the ramp entrance. The hypotenuse of the ball deflector defines a ball deflection surface. When a game ball rolls down the ramp, such as during roll back it is directed away from one of the side walls of the ramp by the ball deflection surface so that it later avoids an undesirable location on the playfield. A bifurcated entrance plate is connected between the ramp entrance and the playfield so that the ball deflector has a minimal effect upon a game ball entering the ramp.

  • Patent number: 5507488
    Abstract: A ball diverter located in a ramp or other ball path is moveable between first and second positions and is used to selectively divert a pinball between two paths. The player uses buttons located on the game cabinet to control the position of the diverter and the path travelled by the ball. The mechanism for moving the diverter includes two solenoid coils which are arranged such that the diverter can be held in either the first or second position indefinitely without either solenoid being continuously actuated.

  • Patent number: 5494286
    Abstract: An electromagnet is mounted beneath the playfield. Sensors, such as optical switch pairs, are positioned on the playfield in operative relation with the electromagnet to detect the ball and to produce a signal in response thereto. The microprocessor, in response to such signals, briefly pulses the magnet to accelerate the ball or energizes the electromagnet for an extended period to grab and hold the ball. When the ball is held, the magnet is thereafter deenergized and briefly pulsed to propel the ball on the playfield. In one embodiment, a plurality of electromagnets are provided along a ball path which are operated sequentially by the game microprocessor to move the ball from magnet to magnet in a stepped manner.
