Abstract

670,979. Sparking plugs O'CARROLL, T. J.. March 21, 1949, No. 7575/49. Class 7(iv) In a sparking plug comprising an electricallyinsulated - central electrode A having an exposed end in which the spark passes axially of the plug between said end and a radiallyextending earthed electrode J, an intermediate electrode K is located in the spark gap and insulated from the other electrodes so as to split the spark produced into two consecutive sparks. Part of the electrode K is embedded in the insulation D and is of arcuate cross-section formed concentric with the electrode A whilst the tip L has a profile as shown in Fig. 3. The electrode J is formed integral with or attached to the casing E and may comprise two or more tongues. The insulation is made from a transparent material or a synthetic resin of the thermosetting type.
