1 Claim.
This invention relates to an attachment for spark plugs.
In its preferred embodiment our invention is an attachment or fitting for spark plugs which is readily adapted to the conventional types of spark plugs and has for one of its objects a means for inducing a current of air to flow through the spark plug over the porcelain core and electrodes and to prevent or to remove any deposition of foreign material, oil or carbon upon the internal structure of the spark plug.
Another object of our invention is to provide for the entering into the explosion chamber of a cylinder of an additional supply of air in order that the explosive mixture of air and gasoline vapor can be more nearly completely burned. We have observed throughout many tests that when the fuel is thus efiiciently burned the mileage procurable from a definite unit of gasoline is appreciably increased.
A further object of our invention is to facilitate the starting of a gasoline or fuel motor, especially under adverse circumstances, by providing for the passage of an additional current of air through the spark plugs into the cylinders in order to effect an increased vaporization of the fuel. Moreover, these advantageous purposes are incorporated in a device that is readily fitted or adapted to all types of conventional spark plugs without in any manner shortening or refabricating the spark plugs.
As previously premised, special means for the variously described purposes have been devised and been combined with the other instrumentalities of our invention, all of which will be now described in detail on reference to the accompanying drawing, in which:-
Figure 1 is a view in elevation of a spark plug, showing the fitting applied.
Figure 2 is a longitudinal sectional view of an assembled spark plug and fitting along the line 22.
Figure 3 is a transverse sectional view of an assembled spark plug and fitting along the line Figure 4 is a view in elevation of a spark plug, showing a modified fitting applied.
Figure 5 is a longitudinal sectional view of an assembled spark plug and a modified fitting along the line 5-5.
Figure 6 is a transverse sectional view of an assembled spark plug and a modified fitting along the line 6-6.
Referring to the drawing in which like reference numerals indicate like parts, I designates a tubular body member of a spark plug of conventional type. The side wall of the member I is threadedly bored at 2 for the purpose of receiving the threaded nipple 3. The nipple 3 pene- 5 trates to the inner surface A of the tubular member l. Its outer end 5 is open to the air in contact with the spark plug. The canal 6 running throughout its length terminates at the inner end I of the nipple which opens directly into the annular space 8 between the porcelain core 9 and the inner surface H] of the threaded shank II of the spark plug. Disposed within the canal 6 is a check valve ball l2, said ball being of such dimensions as to move freely within the nipple 3 and yet large enough to engage snugly the seat l3 at the outer end of the nipple 3. In order to prevent an excessive movement of the ball 12 toward the inner end 7 of the nipple a stop pin [4 is disposed centrally of the inner end l and is adapted to be engaged by the ball [2.
In Figures 4, 5 and 6 a modified form of the attachment is shown. With the porcelain core 9 removed the tubular member l is drilled to form the cylindrical canal 6 through one side of its wall and the conical canal l5 through the opposite side of its wall. A plurality of such borings can be made through the wall of the tubular member I The gasket I B is split (3:) wherever it abuts upon the conical canal l5 in order to give free passage to the air from outside the spark plug to the annular space 8 between the porcelain core 9 and the inner surface I 0 of the threaded shank ll A check valve ball I2 is disposed within the conical canal l5, said ball being of a size to move freely within the conical canal l5 and yet large enough to engage snugly the seat IS. The inward movement of the ball I2 is checked by the porcelain core at 6. The cylindrical canal 6 is securely and threadedly fitted with the plug IT.
The device as shown in Figures 1, 2 and 3 or as modified in Figures 4, 5 and 6 operates in the following described manner. Upon the intake stroke of the motor piston, the check valve ball l2 will be drawn inwardly against the stop pin 14 and a current of air will be drawn through the canal 5 into the annular space 8 and thence over the electrodes l8 into the cylinder of the motor. As can be readily recognized, this supplemental supply of air not only promotes a further vaporiza tion of the gasoline but also purges the electrodes l8 of adhering carbon or oil and induces a more efiicient combustion of the explosive mixture.
Upon the compression stroke of the piston, the ball I2 is forced to engage securely with the seat l3 at the outer end 5 of the canal 6. Thus the compression resulting from the firing of the explosive mixture is in no way impaired as a result of a leakage of the products of combustion and the entire force of compression is applied to the performance of useful work. Actual experiments have demonstrated that the output of a motor equipped with our improved spark plugs is considerably increased, especially from the point of view of yielding more mileage from a unit quantity of fuel.
While the constructions as shown and described are the preferred embodiment of our device, nevertheless the same may be modified in detail without departing from the spirit and the scope of the invention as defined in the annexed claim.
Having thus described our invention, we claim as new and desire to secure by Letters Patent:
A combination of a porcelain core and a tubular element of an air valve comprising a plurality of check valve balls disposed within conical perforations in the wall of said tubular element, the exterior surface of said wall forming an outer valve stop, said conical perforations communicating directly through the cut away portions of a split washer with the annular space between the inner surface of said tubular element and the said porcelain core and the edges of said split washer forming an inner valve stop.
