Abstract: A multi-purpose suspension system for resiliently mounting a rigid body on a rigid base assembly includes an intermediate frame supported from the base assembly by a spring for providing limited relative angular movement about an axis vertically aligned with the central longitudinal axis of the base assembly and for pivotally supporting the body for limited horizontal and vertical movement relative thereto, and an arm pivotally mounted on at least one end of the base assembly for providing limited angular movement relative thereto about an axis parallel with the axis of rotation of the intermediate frame, the arm being connected by links to opposite sides of the body.

Abstract: A vehicle suspension system capable of accommodating considerable upward and downward movement of individual wheels and having a lever which is pivotable relative to the chassis about an axis extending longitudinally of the vehicle against the action of a spring, one end of which is slidable transversely relative to the lever.
