Abstract
Abstract A pipe cover spacer and diameter compensator in the form of an elongated curved bendable ribbonlike strip having a relatively flat skirt portion abutting and secured to the inside surface of the pipe cover and inwardly radially extending fingers terminating into relatively flat bendable tabs angularly extending from the fingers to yieldably bear against the surface of the pipe to resist lateral movement between the cover and the pipe and to compensate for any variation in the space between the cover and the pipe.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
135 words
An improvement in a pipe cover spacer and diameter compensator comprising a. a substantially elongated metallic strip arcuated throughout its length into a semicircular form, b. said strip providing a smooth surfaced skirt portion adapted to be fixedly secured to the inner surface of the pipe cover, c. a plurality of equidistant angularly disposed yieldable fingers formed on one edge portion of said skirt and extending in a direction away from and inwardly of the arcuated plane of said skirt, d. and pipe-engaging tabs carried by the free ends of each of said fingers and angularly disposed with respect thereto so as to lie in a predetermined arc, with said fingers and said tabs yieldable with respect to each other and to said skirt to accommodate a peripheral sector of the pipe to be covered.
