Abstract:
An automatic apparatus for leveling suspended articles or hung objects to an angle relative to a reference. The shift lever assembly (112), used as a gravity reference, is activated when the pendulum member swings horizontally in response to slightest inclination or tilt, thereby causing the conductor pin (114.14) to contact one side of a pair of conductor plates (114.24b) or (114.24b). The contacting of the conductor pin to one side of the pair of conductor plates (114.24b) or (114.24b) completes the electrical circuit and allows the electrical storage device (118) to provide electrical current to the planetary motor (116), causing it to rotate. The turning of the planetary motor (116) causes the shift lever assembly (112) to automatically shift the elongated lever arm (112.10) against the rigid axle (122.22), thereby shifting the center of balance of the object in the opposite direction of the rotation of the wheel-like driven gear (112.20). Leveling occurs when the elongated lever arm (112.10) returns to its original vertical orientation, the conductor pin (114.14) is no longer in contact with either side of the pair of conductor plates (114.24a) or (114.24b), and the motor stops turning.
