Abstract

428,844. Sparking-plugs. SOC. RODDO, Route de Paris, Charbonnieres-les-Baines, Rhone, France.-(Assignees of Doignon, L.C. ; 16, Montee de St.-Cyr, Rambert-L'ile Barbe, Rhone, France) Aug. 14, 1933, Nos. 22712, 22713, and 22714. Void [Abridged as open to inspection under Sect. 91 of the Acts, Feb. 14, 1934]. [Class 7 (iv)] The earthed electrode q is integral with or screwed to a metal sleeve m permanently attached to the insulator. The sleeve may be externally threaded to engage within the casing, or flanged and secured by an internally-threaded cap f with interrupted, quick-pitch threads. The usual plug casing may be omitted. Cooling may be promoted by providing aircirculating passages in the casing or cylinder boss and around the outer part of the insulator.
