Abstract
The invention herein is a coil spring assembly for the suspension of a vele including a series of plates whose tapered edges protrude between the coils of the spring. The plates are slideably mounted on bolts parallel to the longitudinal axis of the spring, the bolts being moveable toward or away from the longitudinal axis of the spring. The resulting movement of the plates toward or away from the spring causes a thicker or thinner zone of the tapered edge of the plate to be disposed between the spring coils, thereby changing the degree to which the plates stiffen the spring.
