Abstract

505,085. Sparking-plugs. J. Oct. 28, 1937, No. 29453. [Class 7 (iv)] The outer part of the insulator is made of pure refractory insulating- material and the core integrally therewith and wholly or in part of such material in an impure state or containing powdered metals or metallic oxides in quantity sufficient to afford the necessary conductivity for the high-tension current. The conductive material may be provided only at or around the end towards the combustion chamber, or may extend from end to end through the insulator. A metallic cap may cover the sparking end of the insulator, and metallic members extend into the insulator to make contact with the conductive zones. Reference has been directed by the Comptroller to Specification 198,345. [Class 7 (iv)].
