Abstract

194,196. Guinness, K.. E. L. May 2, 1922. Sparking-plugs. - The mica or other insulating material is consolidated about the electrode surrounding portion, as by drawing down through one or more dies, or rolling the surrounding metal portion. The whole or inner end onlv of the metal portion, which may be the plug body, may be swaged. The inner end of the casing is then threaded, and part may be removed so that the insulator may project slightly. The inner end of the insulation may be machined out conically; a metal ring E may be fitted to protect the thin edge of the insulator. At the outer end the plug is completed by washers F and a nut G.
