Abstract
142,434. Delta Co. April 29, 1919, [Convention date]. Sparking-plugs.-Relates to plugs of the kind in which a central electrode 5 is carried by an insulator 3 secured into a casing 2 by means of an annular nut 12, and consists in making the insulator and the nut with interengaging conical faces 11 which form a tight joint when the nut is screwed in. A nickel pin 6 is screwed to the end of the central electrode so that its triangular sparking head 6<1> lies in a circular recess in the other sparking terminal 8 in one with the casing 2.
