ABSTRACT:
An adjustable-effectiveness support spring device for vibration-isolating support of an airborne load subject to varying g forces in both positive and negative directions. A vertically movable load support rod is interconnected for support by a mounting base through the medium of a low pickup value helical spring means and a rockable lever assembly. Adjusting position of the spring means and a fulcrum means along the length of the lever assembly adjusts the support effectiveness of the weak spring means as well as the direction of its effort imparted to the support rod.
