Abstract: A radial cushioning apparatus including an inner member, an outer member, and an elastomer. The inner member accommodates a shaft passing endwise therethrough. The outer member is arranged in radially spaced relation from the inner member. The elastomer is secured to the inner and outer members and defines a plurality of collapsible spaces into which elastomer material can flex thereby cushioning radial deflection of the shaft.

Abstract: A one-piece elastomeric spring having four spaced end portions all joined to and extending from a common body portion. Two end portions are commonly disposed to each side of an axis of the spring such that each end portion can independently deflect when a force is applied thereto. The one-piece spring is formed from a preform formed from an elastomer which is normally free of spring-like characteristics. The elastomer from which the preform is created has a molecular structure along with a ratio of plastic strain to elastic strain greater than 1.5 to 1. The molecular structure of the preform is oriented in at least one direction so as to allow a predetermined spring rate to be imparted to the preform whereby transmuting the preform into an elastomeric spring.

Abstract: A method of making a curved compression spring comprising the steps of: providing a monolithic preform having first and second end portions with a curved mid-portion therebetween, with the preform being formed from an elastomer which is free of spring-like characteristics, and with the preform having an initial predetermined length defined by a longitudinal distance between first and second end portions, and wherein the elastomer from which the preform is formed has a molecular structure along with a ratio of plastic strain to elastic strain greater than 1.5 to 1; and, working the preform so as to orient the molecular structure of the elastomer in at least one direction while transmuting the preform into a compression spring.

Abstract: A compression spring created from a preform made from an elastomer which is free of spring-like characteristics and has a ratio of plastic strain to elastic strain greater than 1.5 to 1. The spring has elongate body with first and second longitudinally spaced free ends along with first and second generally planar arcuate surfaces extending between the ends. As a result of working the preform, portions of the elastomer from which the preform is created are oriented and the preform is transmuted into a curved elastomeric spring.
