ABSTRACT:
Three adjustable supports, positioned at the vertices of a triangle, are used to support one structure from another structure. In one form of the support, a post threaded at its lower end extends from the first structure to a slot in the second structure. A spring is captured between a shoulder on the post and a facing shoulder on the second shoulder at the bottom of the slot. A threaded end of the post extends through an oversize bore in the second structure. A spherical washer has a flat side resting against the outer surface of the second support, and a spherical washer is engaged to the threaded end of the post such that the spherical surface of the washer contacts the spherical surface of the nut to provide freedom of movement.
