Abstract

637,707. Making cased springs. FROST, L. C. B., FROST, A. M. B., and DONNELLY, W. V., (trading as FROST & CO., C. B.). April 5, 1948, No. 9440. [Classes 83 (ii) and 83 (iv)] [Also in Group XXXII] Drawing-dies.-A method of manufacturing a spring for withstanding bending, compression and deflecting stresses, consists in threading a core 2, Fig. 1, through a tube 1 so that it lies freely in the bore of the tube and cold drawing the cored tube through a die or dies 5 to contract the bore into physically gripping engagement with the exterior of the core. The ends of the tube may be closed or sealed by end caps or plugs, or may be flattened thereby forming anchorages for the spring. The spring may be of helical form, Fig. 2 (not shown). A spring mounting may be formed by a pair of springs 1, 11 acting between a base member 14 and a horizontal load member 16. The spring 1 is stressed as a pillar and the spring 1<SP>1</SP> is stressed in tension. The springs 1, 1<SP>1</SP> are connected by a T-piece 15 and the member 16 is secured to the metal tube of the spring 11 by a set screw 19. Specification 574,561, [Group XXXII], is referred to.
