Abstract
A wire rope isolator includes a wire rope and a pair of mounting blocks. The mounting blocks comprise of a pair of cylindrical elongated end flanges that are connected tangentially to each other by a web that has a thickness that is less than the diameter of the flanges thereby allowing the lower section of each flange to extend downward from each web. A hole passes axially through each flange. Wire rope is passed through each flange hole so that the lower surface of each web faces that of the other web and the pair of flanges of one mounting block are offset 90.degree. to the pair of flanges of the opposing mounting block. Four U-shaped half loops of wire rope, with sufficient slack to impart elastic qualities to the wire rope, are formed. The U-shaped half loops extend outward at angles of about 45.degree. from the mounting blocks in a cloverleaf formation. Mechanical bonds, forged by plastically deforming the extending lower sections of the flanges in each mounting block into locking contact with the wire rope, secure the wire rope and maintain the cloverleaf formation.
