Abstract

732,313. Coil springs. EATON MANUFACTURING CO. July 10, 1953 [Sept. 10, 1952], No. 19197/53. Class 108 (3). A coil spring is made of a wire of substantially keystone shape having its substantially parallel sides 12<SP>1</SP> connected by a straight side 16<SP>1</SP> at the external periphery of the spring, and at the internal periphery of the spring, by a convexly curved side 14<SP>1</SP> formed by a large radius central section connected to the sides 12<SP>1</SP> by two curved sections of lesser radii. After coiling (Fig. 1, not shown) the sides 121, 121 become parallel.
