Abstract: A box spring assembly which includes a generally rectangular frame, a plurality of upwardly extending wire springs mounted on the frame, and a wire grid supported on the upper ends of the springs so that the grid and springs cooperate to yieldably resist downwardly directed bedding loads. Each of the springs has a body comprised of two side-by-side arcuate portions formed integral at their upper ends with torsion bars that are connected by a connecting bar located between the arcuate portions. The arcuate body portions thus resist bedding loads with bending stresses and without any areas of stress concentration that would cause early spring failure. The torsion bars in each spring divide the spring load and resist bedding loads principally with torsional stresses, the combination of both bending and torsional stresses in the springs enabling increased load-resisting capabilities in the springs with a resulting efficient use of spring wire material.

Abstract: A wheel for lessening rolling resistance and other forces that retard the rolling of the wheel consisting of a circular wheel rim, a hub member positioned concentrically within the wheel rim and a spoke arrangement connecting the wheel rim with the hub member for storing and releasing externally applied energy to provide propulsive torque to the wheel. The spoke arrangement is formed from a single strand of wire that is wound around the hub and is extended to the rim to form spoke loop portions. As the wheel is rolled over a supporting surface, each spoke loop portion is flexed as the portion of the wheel adjacent thereto engages the roadway. As that portion of the wheel approaches a point where it breaks contact with the roadway the spoke portion closest thereto unflexes imparting a torque on the wheel in the direction in which it is being rolled.
