V SPARK- PLUG.
Specification of Iietters Batent. Patented Dem 13 192 1 Application filed September 2, 1919. Serial No. 321,193.
To all whom it may concern:
Be it known that 1, JAMES HARRY TOWN- SEND, a citizen of the United States, and residing at Gloversville, State of New York, have invented certain new and useful Improvements in Spark-Plugs, of which the following is a specification.
The invention relates to such improvements, and consists in the novel construction, and combination of parts, herein described and subsequently claimed. 7
Reference may be had to'the accompanying drawings, and reference characters marked thereon, which form a part of this specification.
Similar characters refer to in the several figures therein Figure 1 of the drawing is a front view in perspective, showing my improved spark plug broken away for the convenience of illustration. 7
Fig. 2 is a sectional view of the insulator and support nut on electrode.
Fig. 3 is a sectional view of the metal agitating member removed.
Certain of the objects of the invention are to facilitate scraping and agitating the insulator in close proximity to the electrode on a spark plug while in operation; to provide an insulator that can be supported in a similar parts,
' metal shell, said shell having means to support said insulator to form an air-tight chamber; to provide a self-cleaning spark plug, having a metal funnel shaped agitator, slidably mounted on power electrode, with means for supportin and causing the agitator to tip and rocr; its upper edges cooperating with the walls of the circular groove in the insulator; the said wall tapering in a sheering manner with the edges of the agitator; said agitator having means whereby it is lifted with the expelled gases in an engine, and when settling down within a close proximity to spark gap will ar and rock away lumps of soot that frequently form over a spark gap.
Referring to the drawing wherein the invention is shown in preferred form, 1 represents a spark plug shell, having an inside flange, 2, that supports a gasket, 3. The in- V sulator, 4, becomes tightly seated, making an air-tight chamber, 5, when the bushing, 6, is screwed down. The member, 7 is allowed to tip and agitate, being loosely mounted in a slidable manner at its lower extremity on 8. A circular groove, 9, surrounds the power electrode, 8, the wall of said, 9, tapering away from electrode toward the roof of said groove, 9; the lower agitating end, 10, provides a means to keep the spark gap open by its different movements on the nut, 11; said, 11, having an oval top forming the bearing support for the agitator, 7 said, 7 may be lifted by the escaping dead gases forced against the under surface of a dish shaped flange, 12.
The ground electrode, 13, is wider near the spark gap, so as to co-act with the metal parts on power electrode, 8, forming the spark gap.
Under the arrangement shown in Fig. 2, the half section of, 4, shows the supporting means, 14: and 15, as used in Fig.1. The
oval top, 16, on said, 11, keeps the agitator in an unbalanced condition at all angles with, 9, as shown in Fig. 1. Under the arrangementshown in Fig. 3, the half section of, 7, shows the scraping edges, 17 the funnel shaped wall, 18, is provided with. an aperture, 19, through which removed particles sift out.
The'aperture, 20, forms a bearing that allows the member, 7 to rock,.twist and slide on power electrode, agitating atall angles with the groove in the insulator as shown in Fig. 1, and Fig. 2.
The annular flange, 12, having a dish formed under plane, adapted to ride the expelled gases, pushing the scraping edges on, 7 up the side walls of the said groove, 9, as shown in Fig. 1.
W hat I claim a new and desire to secure byLetters Patent is j 1. In a spark plug; a metal shell provided with a flanged support around its inner wall adjacent the lower extremity thereof; an insulator having a circular V shaped groove; and a supporting shoulder means forming an air-tight chamber and a gasket therein; an electrode extending axially through said insulator and center wall of said groove; a funnel shaped'agitator mounted on said electrode with means to agitate and engage with said groove; a nut fixed on the end of said electrode forming a support for said agitator that slidably engages with said electrode and said nut; said nut 'co-acting with the ground electrode forms the spark gap.
2. In a spark plug; a metal shell provided with a flanged support around its innerwall adjacent the lower extremity thereof; an
form an air-tight chamber; a circular V shaped groove in said insulator forming a tapering wall around a power electrode; a
funnel shaped agitator having an annular dish shaped flange to lift the said agitator against the upper wall of said groove; an aperture through wall of said agitator releasing dropped particles of soot; an aperture in said agitator slidablyv engaging around and with the power electrode and 10 support nut; said nut having an oval top bearing, causing said agitator to tip and sway at all angles with the said groove. around said power electrode.
In testimony whereof, I havev hereunto 15 set my hand this 29th day of August, 1919.
