Combination tilt switch and playfield incline indicator

A pinball game, comprising:

• a) a cabinet supporting an inclined playfield;
• b) a first member supported for pivoting movement relative to the playfield;
• c) means for locking said first member at an angle relative to said playfield, said means for locking includes visual markings indicative of the desired angle, said angle corresponding to the desired angle of incline of the playfield;
• d) said first member supporting an electrically conductive pendulum and an electrical contact normally spaced therefrom, said pendulum and contact when touching closing an electrical circuit for signalling that the game has been tilted during play;
• e) means for altering the incline of the playfield to position it at a desired angle relative to the horizontal, said pendulum being centered relative to the contact at said desired angle.

A method for setting the angle of inclination of the playfield of a pinball game and for detecting tilting of the game away from said angle comprising the steps of:

• a) mounting a first member for pivotable movement relative to said playfield;
• b) locking said first member at an angle relative to said playfield, said angle corresponding to the desired angle of incline of the playfield;
• c) mounting an electrically conductive pendulum and an electrical contact on said first member such that when the game is tilted during the game the pendulum will touch the contact to complete a circuit for signalling a tilt condition;
• and
• d) altering the inclination of the playfield prior to game play until said pendulum is centered relative to the contact whereby the playfield is at the desired angle of inclination.

A pinball game, comprising:

• a) a cabinet supporting an inclined playfield;
• b) a first member secured to the cabinet at a known angle with respect to vertical;
• c) a second member supported for pivoting movement relative to the first member;
• d) means for locking the second member at an angle relative to the first member, said angle corresponding to the desired angle of incline of the playfield, and means for indicating said angle;
• e) said second member supporting an electrically conductive pendulum and an electrical contact normally spaced therefrom, said pendulum and contact when touching closing an electrical circuit for signalling that the cabinet has been tilted during play;
• f) means for altering the incline of the playfield to position it at the desire angle, said pendulum being center relative to the contact at the desired angle.
