Abstract

139,050. Green, H. April 1, 1919. Spiral springs. - Spiral springs are formed with projecting points on their meeting surfaces which are arranged in staggered relationship so that the relative slipping of the convolutions is not interfered with. The projections may be formed as conical projecting points d, Fig. 3, or projecting spurs g, Fig. 9; or pins or the like or edge clips may be secured to the spring.
