Abstract

172,185. Elverson, A. J. H. Oct. 14, 1920. Sparking-plugs.-The insulator 9 is inserted from the inner. end of the plug, and, together with the perforated fibre cap 4, is retained in position by the nut 10 on the outer end of the electrode. Cooling is further promoted by openings in the casing. Two shoulders 7, 8 are formed on the electrode, one abutting against the end of the insulator and the edge of the other forming one side of the spark cap. By interposing a spring between the nut 10 and cap 4, the electrode 6 mav be depressed and petrol for starting run into the cylinder.
