ELECTRIC IG NITER FOR EXPLOSION-MOTORS.
Specification of Letters Patent.
Patented. m 14, 1907.
Application filed July 2,1904. Serial No. 215,072-
To t whom it may cone-e772,:
Be it known that I, WILHELM SANDER, a citizen. of the Republic of Switzerland, and a resident of Seefeldstrasse 17, Zurich, Switzerland, have invented certain new and useplohion-Ivlotors, of which the following is a specification. This invention refers to an electric igniter for explosion motors, in which, to secure as nearly as possible reliable ignition, short-circuiting through carbonaceous orother deposits is avoided.
The drawing represents a longitudinal,
central section of a plug en'ibmlying a practical form of my invention I A metallic plug 6, threaded to screw into the cylinder wall of an internal combustion engine, surrounds a concentric annular electrode b which is separated from said plug by an annular space i, and said plug b supports an insulating socket c which is held in position. by a ring nut Carried tightly by this insulating socket c and rendered centrally and. longittuhnally ad ustahIe by nuts 61 and a, is an :gnitcr pin a, which passes centrally through a chamber it within the electrode I ending-inv a terminal disk g. The concentric space or chamber 2' between the central nular-electrode surrounded by said plug and separated. therefrom by a concentric-annular-space, a central-electrode disposed within said concentric annular-electrode and out of contact therewith, and a terminal-disk for said central-electrode. In witness whereof I have hereunto set my hand in the presence of two witnesses.
