SPARK PLUG FOR GAS ENGINES.

CHARLES R. WINSTON, 0F RICHMOND, VIRGINIA.
SPARK-PLUG For. GAS-ENGINES.
Specification of Letters Patent.
Patented June 5, 1917.
Application filed December 4, 1916. Serial No. 134,890.
'To all 11:72am 52. may concern:
:Be it known that I. CHARLES R. WinsToN, a citizen of the United States. residing at Richmond. inthe county. of Henrico and State of Virginia. have invented certain new and useful Improvements in Spark- Plngs for Ga s-Engines. of which the following is a specification.
My invention relates to improvements in spark plugs for gas engines.
The object of my invention is to providea spark plug, in which the outer or ground point is removablv held in the plug and can be replaced if broken. and also providing means wherehv the said pointcan be adjusted up or down so as to bring the spark higher or lower in the cvlindergas is desired. This has been found advantageous in that some plugs are longer than others and would necessarily extend farther into the cylinder and by the adjustment of the outer point all of the sparks within the cylinder can be brought into a horizontal alinement.
Another object of my invention is to provide a spark plug in which the ground.
point can be made of an ordinary piece of wire in the event that a regular point is not obtainable.
A still further object of my invention is to have all of the parts of the plug of the ordinary structure so that my improvement can be readily applied thereto.
In the accompanying drawings,
Figure 1 is a side elevation partly in section of my improved spark plug;
Fig. 2 is a horizontal transverse sectional view taken on the line 22 of Fig. 1:
Fig. 3 is an enlarged perspective view of the lower end ofthe spark plug showing the ground point and holding sleeve in their separated relation.
Referring now to the drawings. 1 represents the ordinary metal sleeve having screw threads 2 which screwinto the head of the cylinder and provided at its upper end with a nut 3. wherebv the plug isscrewed in or out of the cylinder. Screwed in the ordinarv manner in the sleeve 1 is the porcelain stem 1 to which is secured the wire 5 making contact with the metal bar carried thereby and extending downwardly through the sleeve and designated by the reference numeral 6. all of which is well understood and needs no further description.
The lower end of the sleeve is reduced and screw-threaded, as indicated at 7, and
screwed thereon is a thin sleeve 8, the diameter of which is slightly less than the diameter of the threaded portion 20f the sleeve, so that it will allow the plug to be readily inserted in the head of the cylinder without the sleeve coming in contact with the threaded portion of thecvlinder. The reduced threaded portion 71s provided with two oppositely arranged openings 9 whichhave communicating therewith the grooves 10 which extend down through the lower endof the threaded portion 7. The threaded portion Tbelow the openings 9 are provided with the two oppositely arranged openings 11 which have grooves communicating therewith and said grooves, like grooveslO, extend to the lower end of the threaded portion.
The ground point is preferably made of a steel rod 13 having at its upper end a laterally turned portion 14 which is of a length approximatelythe thickness of the threaded portion 7, as fully shown in Fig. 1 of the drawings. and has at its lower end the laterally turned portion 15 which extends inwardly to a point adjacent the point 6. Thesleeve 8 is screwed on the threaded portion 7 over the rod 13 and firmly holds the point in position. Should it be desired to. lower the spark in the cylinder the sleeve 8 is re-.
the spark can be raised or lowered in the cylinder andshould the ground point become broken another point could be made T he rod 13 enters the groove 10 as I of the ordinary piece of copper wire and readily placed in the plug. Thisstruct-ure also enables the ground point to be removed for the purpose of cleaning the carbon or other deposits from around the point within the sleeve 2 and the threaded portion 7. Having thus described mvinvention. what- I claim as new and desire to secure by Letters Patent. is:
1. A spark plug comprising a sleeve having a threaded portion adapted to be screwed into the head of. the cylinder. a
porcelain center. a pointcarried by the porcelain center and extending downwardly through the sleeve below its lower end, a
oint adjustably carried by the outer face of the sleeve, and means surrounding the sleeve and holding the point in its adjusted position on the sleeve.
2. A spark plug comprising a sleeve having a threaded portion adapted to be screwed into the head of the cylinder, a porcelain center, a point carried by the porcelain center and extending downwardly through the sleeve below its lower end, a point adjustably resting in grooves in the outer face of the sleeve, and a ring screwed on the sleeve and holding the point in its adjusted position thereon.
3. A spark plug comprising a sleeve having a threaded portion adapted to be screwed into the head of the cylinder, a porcelain center, a point carried by the porcelain center and extending down through the sleeve below its lower end, the lower end of the sleeve having areduced threaded portion provided with horizontal openings, a U- shaped point having its upper end entering one of the openings and its lower end extending inwardly adjacent the other point and a ring screwed on the threaded reduced portion of the sleeve for holding the point in position.
4. A spark plug comprising a sleeve having a threaded portion adapted to screw into the head of the cylinder, a porcelain center, a point carried by the porcelain center and extending downwardly through the sleeve below its lower end. the lower end of the sleeve having a reduced threaded portion provided with openings different distances from the lower end of the sleeve and having vertical grooves communicating with the openings and extending downwardly to the lower end of the sleeve, and a point having a laterally extending upper end entering one of the said openings, and a laterally extending lower end extending to a point adjacent the other point, and a sleeve screwed upon the reduced threaded portion of the sleeve on the outside of the point and holding the point in its proper position,
5. A spark plug comprising a sleeve adapted to be screwed into a cylinder, 21 Lorcelain center, a point carried by the porcelain center and extending below the lower end of the sleeve, a point bearing against the outer face of the sleeve and having a laterall v inwardly turned upper end, and means for seeming the point to the outer face of the sleeve.
6. A spark plug comprising a sleeve adapted to be screwed into a cylinder, a porcelain center, a point carried by the porcelain center and extending below the lower end of the sleeve, a point resting in a groove in the outer faceof the sleeve and having an inwardly turned upper end. and a ring screwed on the sleeve and adjustably holding'the point thereon.
In testimony whereof I aflix my signature in the presence of two witnesses.
CHARLES R. WINSTON.
