ABSTRACT:
A device for adjusting the angular disposition of a first object with respect to a plane. The first object is adjustably attached to a second object resting on said plane. The adjustment occurs when there is a change in the angular disposition between the second object and the plane. Two freely rotatable members are attached to the first object adjacent each other. Both members are rotatable in a direction parallel to the angle to be adjusted between the first object and the plane, and each member has a rotary rest position determined by its respective center of gravity. During the change in the angular disposition between the second object and the plane, one of the two members is rotationally fixed with respect to the second object and is rotated from its rest position according to the change in the angular disposition between the second object and the plane. The other of the two members remains in its rest position during the change in the angular disposition between the second member and the plane. An indicator senses the change in rotational position between the two members and controls an adjuster to move the first object and the second object relative to each other to rotate the second member back to its rest position.
