GLOSSARY:
The following terms are referenced by some of the definitions of subclasses 2+.
COIL SPRING an element in the form of a spiral and which exhibits resilient characteristic when distorted from its original shape. May be in the form of a helix, a volute spiral or flat spiral.
HELICAL COIL SPRING
an element in the form of a serial lying on the surface of a cylinder and which exhibits resilient characteristics when distorted from its original shape.
LEAF SPRING
an element comprising a plate or bar or a plurality of superposed plates or bars and which exhibits resilient characteristics when a portion is deflected transversely of length of the element
