ABSTRACT:
There is provided a two point mounting system for the outside end of a spiral spring. The mounting system induces a torsional load on the outside end of the spiral spring to overcome the tendency of the spiral spring coils to move into a non-concentric position. The mounting system comprises a single piece sleeve which has an elongated slot for contacting the spiral spring on opposite sides and inducing the torsional load.
