ABSTRACT:
A conical compression spring having the characteristics of a cylindrical spring of much greater free length. The spring is characterized by wire whose diameter diminishes from base to apex end and by coils whose pitch diminishes from base to apex end such that the ratio of mean coil diameter to wire diameter is constant from coil to coil. Further, each coil diameter is preferably dimensioned to fit within the next larger coil permitting a spring to be designed which exhibits a small solid compressed height.
