Abstract

526,687. Spark ignition coils. LUCAS, Ltd., J., WATSON, E. A., and ALLEN, A. MASSEY-. March 22, 1939, No. 9042. [Class 38 (ii)] In an ignition coil of the type adapted to be mounted on a sparking plug f, successive layers of the secondary winding b are insulated by layers of paper, silk &c. which overhang to form respectively internally and externally coned extensions i, j at opposite ends of the winding. The extension i is supported by a coned part q formed on a core c of ceramic or other insulating material. The extension j fits within an insulating cup r which carries a socket s effecting connection between the sparking plug terminal t and screw u to which the unearthed end of the secondary is connected. The unearthed end of the primary a is connected through a lead n to a terminal o.
