Abstract
Abstract A spacer device for a coil spring including a hard resilient body having an arcuate seat on at least one end portion of the body and a U-shaped socket fixed to the end portion of the body to span the arcuate seat and open laterally of the body for receiving a convolution of the coil spring. When both end portions of the spacer are positioned between the spring convolutions, the axial inward pressure of the convolution received in the socket forces one leg of the socket into the seat and simultaneously causes both legs of the socket to flex around the convolution.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
211 words
A device for supporting in spaced apart relationship adjacent convolutions in a coil spring, comprising: a. an elongated body having a longitudinal axis and first and second opposite end portions, and having widthwise and depthwise dimensions, b. an arcuate seat formed depthwise in said first end portion and having opposed edge portions spaced widthwise, c. a substantially U-shaped socket having inner and outer legs connected by a bight portion, for receiving a convolution, d. said inner leg being fixed to at least one of said edge portions to span said arcuate seat so that said inner leg is normally spaced from said seat, e. the free ends of said legs defining a slot that will accommodate the diameter of the convolution to be received in said socket, f. seat means on said second end portion for receiving a convolution, g. said inner leg being adapted, when a first convolution is received in said socket and a second adjacent convolution is received in said seat means, to flex toward said seat under the axial pressure of said first convolution created by the contraction of said coil spring, and to cause said outer leg to flex around said first convolution so that said slot is less than the diameter of said first convolution.
