Automotive spark indicator
First Claim
1. A spark indicator apparatus for use in detecting automotive ignition spark at various points in an auto ignition system comprising:
- electrical transmission means for electrically connecting a one of said various ignition system points to automotive ground, said transmission means having an interruption therein providing a spark air gap;
means for encasing said spark air gap, said encasing means including a transparent housing completely surrounding said spark air gap, a straight channel passing through said housing, said channel having two larger diameter sections and a smaller diameter section separating said two larger diameter sections, and a pair of abutment shoulders, situated one each at an interface of said smaller diameter channel section with one of said two larger diameter sections; and
means for venting said spark air gap through said encasing means, said venting means traversing at least one change in direction.

Abstract
A spark indication apparatus connectable between the secondary winding tower of an ignition coil or a spark plug distribution tower of an auto distributor or a spark plug wire coming from the distributor, and chassis ground having, preferably, a transmission cable including two separated portions, the intermittent connection thereof may provide a spaced air gap or spark gap space for the generation of an electric spark by current passing through the transmission cable; and having a housing which may encase part of each transmission cable portion and the spark gap space, this housing preferably having a cavity defining a spark chamber, wherein the spark chamber may be vented to the atmosphere through the housing.
