Abstract

186,527. Ellison, G. Oct. 18, 1921. Drawings to Specification. Contacts consisting of a straight helix of wire the coils of which are given an angular set to increase their resiliency by mounting the plain helix in a specially-shaped housing as described in Specification 29822/13 have the angular set formed initially by winding the wire at an inclina.tion on a mandrel or by permanently deforming a plain helix. The helix may be bent into annular form for use with plug contacts.
