Abstract

308,435. Hopps, B., and Lodge, A. M. Feb. 23, 1923. Sparking-plugs.-A metal sleeve a, preferably of copper or other metal of high thermal conductivity, surrounds the central conductor b. Mica wrapping d is fitted about the sleeve a before the conductor is inserted, and mica washers e and a metal collar g are afterwards secured between the shoulder c and nut f. Lateral compression is exerted on the collar g. Specifications 117,362 and 284,391 are referred to.
