ABSTRACT:
A spring system comprising an axially movable, generally conically shaped plug having a flange on its larger diameter end, and a coil spring, within which the plug is axially arranged, formed in two co-axial integral inner and outer coil spring sections. The spring inner section coils having diameters which are sized to closely conform to the portions of the outer surface of the plug which they overlay, and the spring outer section coils surrounding and being radially spaced from the inner section of the spring. The free end of the inner section is fixedly anchored to a support member and the free end of the outer section engages a support surface. The sections are integrally connected by a common coil arranged to engage the plug flange. When the plug is initially moved endwise within the spring, the coils of the inner section are tightened and stretched around the conically shaped plug surface. Further movement of the plug compresses the outer spring section between the plug flange and the support surface.
