AUXILIARY AIR-VALVE.
Specification of Letters Patent.
Patented Jan. 6, 1920.
Application filed November 14, 1918. Serial No. 262,518.
To all whom it may concern:
Be it known that l, VVILSON E. SIMs, a citizen of the United States, residing at Greeneville, in the county of Greene and State of Tennessee, have invented certain new and useful Improvements in Auxiliary Air-Valves, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to an air valve for internal combustion engines.
The object of my invention is to produce an efficient self-adjustable valve, which will admit air to the intake of an internal combustion engine immediately beyond the carbureter, whereby the richness of the mixture is reduced or diluted between the carbureter and the engine proper, producing a marked saving in the consumption of gasolene, promoting combustion and overcoming the rapid accumulation of carbon within the combustion chambers, thereby maintaining the engine or motor at its greatest efliciency for a comparatively long t1me.
Another object of my invention is the construction of a simple, efficient valve which opens and closes in accordance with the de mands of the'motor or engine and in accordance with the suction produced by the piston speed, rendering it unnecessary to adjust the carbureter from day to day on account of the climatic changes.
With these and other objects in view, my invention consists of certain novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.
In the drawings:
Figure 1 is a side elevation of an internal combustion engine showing the relation of the valve of this invention thereto.
Fig. 2 is a sectional view taken on line 2-2, Fig. 1.
Fig. 3 is a perspective view of the auxiliary casing of the valve.
Fig. 4 is a perspective View of the sieve.
Fig. 5 is a view in elevation, and partly in section, of a modified form of the present invention.
Referring to the drawings by numerals, 1 designates the internal combustion engine, or motor which is conventionally shown as provided with the usual carbureter 2 and intake pipe 3. Between the carbureter 2 and the engine 1 and preferably contiguous to the carbureter, I place the auxiliary air valve, which automatically permits air to enter the pipe or manifold 8, as required.
The air valve comprises an outer or primary casing 4 and an inner or auxiliary casing 5. The primary casing 4 is provided with a reduced threaded extension 6 that screws into the pipe or manifold 8. The primary casing is provided with an enlarged outer end 7, which is internally threaded, as at 8. The casing 4 has a seat 9, for the purpose hereinafter described.
The auxilary casing 5 comprises a large inner end 10 which is exteriorly screwthreaded, and this end 10 is screwed into the threaded, larger end 7 of the primary casing 1.
The auxiliary casing 5 is provided with a tapering hollow extension 11, and this casing 5 is provided with a plurality of apertures 12 that perform the function of breathers for permitting air from the outer atmosphere to enter the primary casing and thence the pipe or manifold 3.
However, if it is desired to permit kerosene to enter the manifold 3, for the purpose of cleaning the engine, then a flexible pipe or hose 13 (Fig. 5) can be placed upon the outer end of the reduced extension 11, and the lower end of the hose placed in a receptacle containing kerosene and with the motor running the kerosene will be sucked up through pipe 13 thence through the auxiliary and primary casings of the valve and thence into the engine; to eiliciently produce this action, it is desirable to stop or plug up the apertures 12, and this can be easily done by inserting match stems 15 into said apertures, as shown.
It will be noted that besides producing an efficient air valve, the same valve can be used to clean the engine of carbon, by injecting kerosene therethrough, while the engine is running.
On the inner end of the auxiliary casing 5, at 16, is formed a valve seat. The valvehead 17 is secured to the inner end of valvestem 18, and the outer end of the valve-stem is threaded, and'on this threaded portion is normally positioned lock-nuts or taps 19; each nut 19 is similarly constructed, and between the inner end of casing 4 and'the inner nut 19 is a tapering coil spring 20; the smaller or outer end of the spring rests snugly within the socket, constituted by the annular reduced structure of nut 19 (Fig. 2), and the larger end of the spring rests against the outer end of the primary casing 4 and around the enlarged portion of the auxiliary casing 5.
Engaging the seat 9 of the primary casing 4 is a sieve comprising (Fig. 4) the primary screen 21 and the auxiliary screen 22; the primary screen 21 is provided with a conical central portion 23, and its fiat outer edges rest against the seat 9. The auxiliary or inner screen 22 is placed against the primary screen 21 and between said screen 21 and the inner end of easing 5 is pressure ring 24. This ring 24E engages the inner end of the auxiliary casing 5, and when the casing 5 is screwed tight against the ring 24, said ring will press tightly against the edgesof the two screens constituting the sieve, thereby holding the same seated upon the seat 9.
Among the advantages of this sieve structure are: that the same can be quickly removed and cleaned, and by making the sieve of the structure shown a very thorough and complete cleaning of the air entering the manifold will be accomplished as the conical portion 23 of the primary screen 21 gives the greatest amount of screen to be engaged by the air passing through the device, and yet not placing the screen 21 entirely against the auxiliary screen 22, so that clogging or stoppage of the air through the sieve will not be hastened by foreign substances in the air entering the valve.
The tension of spring 20 is adjusted to a nicety by adjusting the nuts 19, thereby controlling the pressure on the valve-head 17, so that the running of the motor can be governed perfectly with respect to the amount of fresh air entering the manifold through the valve.
In the accompanying drawing (Fig. 2) is illustrated clearly the entrance of the air through the air-valve and the mixing with the mixture coming from the carbureter, breaking the mixture into finer particles before entering the motor.
desirable, and which will appear to one skilled in the art to which this invention relates, and which alterations or changes shall fairly fall within the scope of the appended claim.
What I claim is:
In a device of the class described, the combination of a primary casing, a sieve in said primary casing, an auxiliary casing mounted upon said primary casing contiguous to said sieve, said auxiliary casing provided with a reduced extension and with apertures therein around said extension, a stem slidably mounted in said extension, a piston-head secured to the inner end of said stem and being adapted to close the auxiliary casing, a spring engaging the outer end of the primary casing and positioned around the reduced extension of the auxiliary casing, and a clamping nut upon the stem and engaging the spring for causing the spring to exert an outward pressure upon the stem for holding the piston-head seated upon the primary casing.
In testimony whereof I hereunto affix my signature.
