Abstract

943,466. Coil springs. J. B. TIGRETT. Nov. 19, 1959, No. 23993/63. Divided out of 940,982. Heading F2S. A coil spring 10 comprises an elastic ribbon 12 prestressed both longitudinally and transversely so that in both its coiled and uncoiled conditions the ribbon has a transversely arcuate form, the concave side of which forms the inner surface of the coil. The pre-stressing is affected by drawing the ribbon over a barrel-shaped die to stretch longitudinally the centre portion of the ribbon relative to its edges so that it tends to assume a coiled condition with the centre portion of greater radius than the edges.
