Figure 3 is a bottom plan view of Figure 1. Referring in detail to the drawing, the nu- The core or insulator which is generally designated 9 includes the portion l conforming in shape to the upper bore portion 6 and the lower tapering part I l which is fluted as indicated at l2 at several points of its circumference so as to provide for the passage of cooling gases around and about the portion H. The lower end of the part I 0 of the plug is seated on a compression Washer I 3. The lower end of the portion H is approximately flush with the lower end of the body as shown.
One side of the body has a radial passage M which leads into a circumferential groove IE on the exterior of the portion ID of the insulator which provides for the circulation of cooling gases and air around the adjacent portion of the insulator.
Depending from the lower end at diametrically opposite sides of the body are the lugs 24 and 25 which have openings 26 and 27, respectively, to receive the reduced ends 28 and 29 of the spark point which is generally designated 30.
The sparking point 30 is composed of a shaft 3| which is provided at equal distances from its center with the disks 32, 33 which bound the reduced portion 34 and are so spaced and sized as to present at equal distances from the exposed lower end of the electrode 35 three different sparking points, represented by the adjacent side of the reduced portion 34 and the adjacent sides of the disks 32 and 33.
The reduced ends 28 and 29 of the sparking point 30 turn and laterally move in the openings in the lugs 24 and 25 upon agitation of the fuel chanically throw therefrom any accumulations of oil or soft carbon, so that the sparking points are kept clean and better ignition is obtained.
shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not desire to limit the application of the invention thereto,
and any change or changes may be made in the point at the lower end thereof, said body having materials, and in the structure and arrangement a slidable and rotatable shaft disposed adjacent of the parts, Within the spirit of the invention the exposed end of the electrode, and a pair of and the scope of the subjoined claim. spaced integral disks on said shaft projecting What is claimed is:- from said shaft beyond the free end of the elec- 5 A spark plug of the type described comprising trode and spaced therefrom.
