ABSTRACT:
The disclosed spring mechanism is useful, for example, as a counterbalance or as a spring suspension. The preferred form of mechanism has opposite output parts for connection to the external apparatus. One output part is fixed to two side-by-side torsion-spring columns--two bundles of rods--and the side-by-side opposite ends of the columns bear diametrically opposite cam followers. The second output part is unified with complementary cam tracks for the cam followers of both columns. The spring mechanism has varied characteristics, depending on the shapes of the cam tracks.
