Another ob germs invention is'the provision of a spark plug operable without the formation of a carbon deposit thereon.
Another object of the invention is the provision of a spark plug through which may pass the air supply for a cylinder of an internal combustion engine.
Other objects will be appreciated from a reading of the following specification.
The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawing which forms part of the application, with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made therefrom as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.
In the drawing:
Fig. 1 is a fragmentary longitudinal section through an internal combustion engine showing in side elevation a piston working in a cylinder of the engine and showing, also in side elevation, a spark plug of my invention associated with the motor. V
Fig. 2 is mainly a central longitudinal section through the spark plug of my invention, certain parts being shown in elevation.
Fig. 3 is a horizontal section taken approximately on the line 3-3 of Fig. 2, looking in the direction of the arrows; and
Fig. 4 is an elevational view, partly broken away and partly in section, showing the construction of the lower end portion of the spark plug; and
Fig. 5 is a section taken on line 55 of Fig. 2.
Referringto the drawing for a more detailed description thereof, the numeral 5 indicates an internal combustion motor having a cylinder 6 in which reciprocates a piston '7. A spark plug 8 of my invention is shown in Fig. 1 as secured to the motor or engine 5, the lower end of said spark .plug being in a combustion chamber 9, which is in communication with the interior of the cylinder 6.

The body of the spark plug is interiorly threaded as indicated by the numeral 16 and is threadedly connected to a hollow insulating member 17, which seats on a. gasket 18 resting on an annular shoulder 19 formed in the interior of the plug. A threaded nut 20 threadedly engages the body 10 of the plug and holds in place the mentioned insulating member 17, being seated on a gasket 21, which rests on an annular shoulder 22 formed on said in-' sulating member 17. A brass tube 23, provided with a conical valve seat 24 at its lower end, is disposed centrally in the insulating member 1'7 and is held in position by a shoulder 25 pulled against a corresponding shoulder in the mentioned member 17 and held against said shoulder by a nut 27 threaded to the tube and seated on a gasket 28, which rests on the top of the insulating member 17.
contact with the bottom of the latter. Means are thus provided for regulating the amount of'air which passes through the spark plug. 1 H a The mentioned electrode 30, which functions also as a valve to open and close the air passageway of the spark plug, "opens when the; pressure -withint the cylinder 6- is subatmospheric and closes when the pressure within the cylinder is slightly greater than that of the atmosphere, thus closing the passageway before compression begins. It is evident that a downward movement of the electrode to open the mentioned passageway, allows the air to pass through the spark plug into the combustion chamber 9 and from there into the cylinder 6.
The chamber 32 may be termed a firing chamber since the gas-fuel mixture, which is contained therein, is fired by the sparks passing between the electrodes 30 and 31, the firing of the charge within the chamber 32 resulting in flashes of burning fuel being emitted through the outlet orifices 12 to ignite the charge in the combustion chamber 9 and in the cylinder, 6. The, structure described will evidently accomplish the objects of the invention.
What'isclaimed as new is:
- '1;. ;A spark plug provided with an air inlet and a plurality of air outlets and a passageway connecting said inlet and outlets, and an electrode adapted to open and close said passageway, and means for adjusting the effective size of said inlet,
