Multi-level playing surface pinball machine apparatus

Claim 2

In a pinball machine which defines a play field to receive a rolling ball for pinball play, the improvement comprising, in combination: a ball-retaining aperture defined in said play field, means to provide a plurality of balls simultaneously on said play field, and chute means for directing rolling balls to said ball-retaining aperture, whereby, when said aperture carries a first ball, a second ball rolling in the chute means towards said aperture is prevented from entering said aperture and is deflected by collision with the first ball away from said aperture in a first direction, and means for displacing balls from said aperture and causing them to roll on the play field in a direction other than said first direction.

Claim 3

The pinball machine of claim 1 in which said chute means includes a lower ball chute for guiding balls into said ball-retaining aperture, said lower ball chute being sloped to urge said balls to roll in said first direction.

Claim 4

In a pinball machine which defines a play field to receive a rolling ball for pinball play, the improvement comprising, in combination: a ball-receiving aperture defined in said play field, an upper ball chute provide on and above the play field, said upper ball chute defining a drop aperture through which a ball rolling the upper chute can drop onto said playing surface; and a lower ball chute on said play field to receive balls dropping onto said play field and through said drop aperture, said lower ball chute guiding balls into said ball-receiving aperture in said play field, said drop aperture being occluded by a pivotable, upwardly-biased flap, whereby balls falling through said drop aperture are caused to have rolling motion by said flap into and along said lower chute to roll into said ball receiving aperture.

Claim 5

In a pinball machine which defines a play field to receive a rolling ball for pinball play, the improvement comprising, in combination: a ball-receiving aperture defined in said play field, an upper ball chute provide on and above the play field, said upper ball chute defining a drop aperture through which a ball rolling the upper chute can drop onto said playing surface; and a lower ball chute on said play field to receive balls dropping onto said play field and through said drop aperture, said lower ball chute guiding balls into said ball-receiving aperture in said play field, said drop aperture being occluded by a pivotable, upwardly-biased flap, whereby balls falling through said drop aperture are caused to have rolling motion by said flap into and along said lower chute to roll into said ball receiving aperture.

Claim 6

The pinball machine of claim 3 in which said lower ball chute is sloped to urge said balls to roll in a direction away from said ball-receiving aperture.

Claim 7

A pinball machine which defines a play field to receive a plurality of rolling balls for simultaneous play and a ball launching apparatus for projecting the balls onto the play field, said play field having a ball chute for directing rolling balls toward and into a ball-retaining aperture, and means for displacing balls from the aperture and causing them to roll on the play field in a given direction, the play field being sloped in the vicinity of said ball-retaining aperture in a direction other than said given direction whereby, when said aperture carries a first ball, a second ball rolling in the chute toward the aperture is prevented from entering the aperture and is deflected away from said aperture to roll down the slope in said direction other than said given direction.

Claim 8

A pinball machine which defines a play field to receive a plurality of rolling balls for simultaneous play and a ball launching apparatus for projecting the balls onto the play field, said play field having a ball chute for directing rolling balls toward and into a ball-retaining aperture, and means for displacing balls from the aperture and causing them to roll on the play field in a given direction, the play field being sloped in the vicinity of said ball-retaining aperture in a direction other than said given direction whereby, when said aperture carries a first ball, a second ball rolling in the chute toward the aperture is prevented from entering the aperture and is deflected away from said aperture to roll down the slope in said direction other than said given direction.

Claim 9

The pinball machine of claim 5 in which an upper ball chute is supported on said play field in a manner to permit balls rolling on a predetermined portion of said play field to enter said upper ball chute, said upper ball chute defining a drop aperture through which a ball rolling in the upper chute can drop; and a lower ball chute to receive balls dropping through said drop aperture, said lower ball chute defining said ball-receiving aperture.

Claim 10

A pinball machine which defines a play field to receive a plurality of rolling balls for simultaneous play and a ball launching apparatus for rolling the balls on the play field, said play field having a first ball chute for directing rolling balls into a ball-retaining aperture in said play field, and means for displacing balls from the aperture and causing them to roll on the play field in a predetermined direction, the play field being sloped in the vicinity of the ball-retaining aperture in a direction other than said predetermined direction whereby, when said aperture carries a first ball, a second ball rolling in the ball chute and attempting to enter said aperture is prevented from entering the aperture by said first ball and is deflected away from said aperture to roll down the slope in said direction other than said predetermined direction; a second ball chute comprising an upper ball chute supported on said play field above said first ball chute said second ball chute having a drop aperture through which a ball rolling in said second ball chute can drop to said first ball chute; said drop aperture being occluded by a pivotable, upwardly biased flap, whereby balls falling through said drop aperture are provided with rolling motion by said flap to roll in said first chute towards said ball receiving aperture.

Claim 11

A pinball machine which defines a play field to receive a plurality of rolling balls for simultaneous play and a ball launching apparatus for rolling the balls on the play field, said play field having a first ball chute for directing rolling balls into a ball-retaining aperture in said play field, and means for displacing balls from the aperture and causing them to roll on the play field in a predetermined direction, the play field being sloped in the vicinity of the ball-retaining aperture in a direction other than said predetermined direction whereby, when said aperture carries a first ball, a second ball rolling in the ball chute and attempting to enter said aperture is prevented from entering the aperture by said first ball and is deflected away from said aperture to roll down the slope in said direction other than said predetermined direction; a second ball chute comprising an upper ball chute supported on said play field above said first ball chute said second ball chute having a drop aperture through which a ball rolling in said second ball chute can drop to said first ball chute; said drop aperture being occluded by a pivotable, upwardly biased flap, whereby balls falling through said drop aperture are provided with rolling motion by said flap to roll in said first chute towards said ball receiving aperture.
