RUSSELL 0. DINGER, OF MELVINA, WISCONSIN.
SPARK-PLUG.
Specication of Letters Patent.
Application filed May 4, 1918. Serial No. 232,550.
To all whom it may concern:
Be it known that l, RUSSELL O. DINGER, a citizen of the United States, residing it Melvina, in the county of Monroe and State of IVisconsin, have invented certain new and useful Improvements in Spark-Plugs; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art. to which it appertains to make and use the same.
This invention relates to improvements in spark plugs and has for one of its obe jects the provision of a device of t-his character whereby a comparatively large circular spark will be produced between the electrodes of the spark plug, thereby rendering` an efficient spark for the fuel of the engine.
Another object of this invention is theprovision of a circular electrode surrounding the central electrode of the plug in spaced relation so as to cause a comparatively large circular spark and also will not be affected by oil and carbon forming upon the circular electrode.
still further object of this invention is the provision of a spark plug of the above stated character, which shall be simple, durable and efficient, and which may be manufactured and sold at a comparatively low cost.
IVith these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts as will be hereinafter more fully described and claimed.
For a complete understanding of my invention, referenceis to be had to the following description and accompanying drawing, in which:-
Figure 1 is a side elevation partly in, section of a spark plug constructed in accordance with my invention,
Fig. 2 is an end view of the same,
Fig. 3 is a fragmentary vertical sectional View illustrating the electrodes, and
Fig. 4 is a fragmentary sectional view of the circular electrode.
Referring in detail to the drawing, the numeral l indicates a body of a spark plugr having the usual threaded portion Q for threaded engagement with the opening in the cylinder of an engine. The body 1 has mounted therein the insulator 3 carrying the central electrode 4, the insulator 3' being secured in the body 1 by the lock nut 5. The central electrode a depends downwardly through the extension2 in spaced relation thereto. The extension 2 has secured thereto a plurality of downwardly and inwardly directed arms 6 which have their inner ends formed upon a ring 7 constructed of platinum or other material suitable forthe purpose. The ring 7 forms an electrode of circular formation which is disposed about the lower end of the central electrode 4 in spaced relation thereto so that the spark jumping from the central electrode to the ring? will be in a circular path giving a comparatively large spark. The inner face of the ring 7 is flat as illustrated at 8, and the spark is adapted to play upon the flat surface and oil thrown by the pistons of the engine will be caught by the round face of the ring 7 and prevented from coming in contact with the fiat face 8 on which the spark plays. By having the ring constructed in this manner it provides a comparatively dry and clean Patented Dee. 16, 1919.
surface for the spark to work upon at all. y
times.
While I have shown and described theA vin?.` one of their ends formed on the inner end of said body, and their other ends spaced from the end of the electrode, and a ring having a curved outerface formed on the last named ends of the arms and having a flat inner face disposed about the end of the electrode and in spaced relation thereto. In testimony whereof I affix my signature in presence of two witnesses.
