Abstract

487,246. Sparking - plugs. LICHARZ, C. E., and BLACK, A. N. Dec. 16, 1936, No. 34609. [Class 7 (iv)] An annular spark-gap is formed between the head 4 of the central elec trode and the ring 5 mounted in the end of the casing. The electrodes are made of ar alloy of pure nickel anc electrolytic iron, with pure manganese added for strength and toughness The surfaces are coated with electrically de posited iridium. The central electrode is ir two parts united by ar internally-threaded sleeve 15. Transverse or longi tudinal ribs 15a are form. ed on the outside of the sleeve, and the inside is separated by an air-gap from the greater part o: the part 3b of the centra electrode. Materia known under the Regis tered Trade Mark " Mycalex " is used for the insulating-member 11. Cooling of the sleeve 15 is promoted by the provision of perforations 12.
