To /LZZ whomv it may concern.- y y Y y Be it known thatI, WInLIA'M READLE, actzen of the United-States, 'vresidingat Elmira, in the county-ol" Chemung'and State'of New York, have invented certainnemend-useful Improvements inVaporizing-Valves folExplosive-Engines andIfd'o hereby 'declarethe following to be afull, clear, and exact descri ption of the invention,-` such as will enable others skilled in the arto Which'fit appertains to make and use tf'li'efsame." f

Myinvention relates to an improvement in vaporizin g-valves' for hydrocarbon, and more particularly for use inconnec'tionV with illuminating, producer, `lnatural gases, or gasoL lene, the primary object ,oftheinvention' bfeing to provide 'means' for thoroughlymixing and vaporizing natural and manufactured gases o r gasolene with an adequate quantity of air on itsway'to thecombination-chamber or place Where it'is to be utilized for eXplosive or other purposes. My invention further consists in improved adjustable means', for 'e'ffectually controlling and regulating the amounts of air and hydrocarbon to the valve; and the invention consists in certain novel features of construction and combinations of parts, which will be'liereinafter more fully described', and particularly pointed out int-heclaim's. j l In the accompan'yingdrawings', Figure l 'ijs a sectional viewfof the valve 4employed.'for

Whifchgit .is attached tothe engine or other object to which it is to be applied. For convenience the shell or casing of this construction is made in two parts, secured together at the joint b, which joint affords a means of access to the interior useful in assembling outer enlarged end, as shown.

the parts ofrlthis formovalve. The upper section A is' provided withA an air-inlet portr 9, closed byvmeans'of'fa'dam per 9'; Surrounding the lowereud. of this air-inlet port is an annular.reserve-chamber kl.` Passing across tbe'portat its ,-lowfer end isf a hydrocarbondotata', one end o'ffwh'ich'eXtends through the' reservecharnber to theouter wall of the casing A' and is adaptedltoreceive a regulating needle valve: having a threaded stem', by'means ofwhich it is screwed in and outf. The'opposite endofthe hydrocarbonduct is i'n communication with the reservechamber" 1 and is lprovided 'with a dared or conical seat oropenin'g'b. Depending from and communicating with the hydrocarbonduct a is a tinted stem 7', preferably located at or approximately at. the center of thedevicedischargingthehydrocarbon, This stem terminates ina cone. -The needle-valve reg- -ulates theV amount 'of'hydrocarbon passing from duct a to the duct 2 ofthestem-7, the valve being Amanipulated by ni'eans of a ,drocarbon-supply.vvk In Fig. l this projecting "nipple "is 'adapted to'r'eceive an externallyscrew-threaded removable'plug 4:, the bore o.'of which'is in alinement andcommunieating with the'duct a. This pl'ug is adjustable in theprojecting-'ni'pple 4' and passes across the reserve-chamber l, its inu'er end conicallylshaped to fit the. conical seat b' of the vhydrocarbon-duct. The outer end of the plugisen'laiged to fit the diameter of the nipple 4', the adjustment of the plug being effected by inserting a suitable instrument for the 'purpose into recesses formed'in'its is obvious. When the valve is used with gasolene, the plug is screwed tightly home, as shown in Fig. l, thus absolutely cutting off communication with the reserve-chamber 1, as the latter is unnecessary when gasolene is used; but when Anatural or other'r gas is the hydrocarbon elmployedvthis plug may be either removed altogether or screwed back from the conical seat b', so that the bore of the plug as Well as the hydrocarbon-duct are Its functionboth in communication with the reservechamber 1.

The interior of the shell or casing is subdivided into two chambers by the discal portion of a valve 12, which is normally seated upon an annular ange 12. The upper of these chambers will for convenience be termed an air-chamber and the lower one the mixing7 or vacuum chamber. An annular series of gas inlets or perforations 6 is made in this flange into the reserve-chamber 1 for the escape of gas therefrom into the mixing or vacuum chamber, and the discal portion of the valve 12 normally or when seated closes these perforatious. Air is fed into the valve through the upper end 9, and its supply may be controlled by the damper 9, and this in turn is locked by the springactuated catch 9", seated in a shouldered aperture 20 in the handle 9. The air thus admitted is intermingled and thoroughly mixed with the hydrocarbon by issuing in two annular jets, one of which is around the outer periphery of the discal portion of the valve 12 just beneath or contiguous to the annular series of gas inlets or perforations 6 and the other through the flutings S 8 in the stem 7 and the inlets or perforations 13 in the conical seat 14 ofthe valve 12. The valve 12 is provided with a stem 15, which is guided and centered in its reciprocations by the way t', drilled through the web 16 of the lower section A of the shell or casing. The valve 14 is normally held seated by the spring 17, its discal portion closing the perforations 6 and its conical seat in engagement with the conical lower end of the stem 7, so as to shut oit communication between the bore 2 of the stem and the'iutings 8 8 and the inlets or perforations 13.

The numeral 10 indicates a vacuum-chamber in communication with the cylinder of the engine and located partly in the two sections of the shell or casing, with the valve 14 operating therein. Valve 14 remains closed so long as the tension of the spring 17 is in excess of the suction created by the receding piston in the vacuum-chamber 10. In other \vords,with each forward stroke of the enginepiston the suction created causes a downward or inward movement of the valve 14, thus simultaneously opening the annular series of perforations 6 and 13 and the hydrocarbonduct 2, so that air and hydrocarbon are finely divided, distributed, and intermingled with each forward movement of the valve in an adequate quantity and suitably proportioned to create a highly-combustible vapor in the cylinder preparatory to each successive explosion. Immediately upon the return stroke of the piston being made the suction-power of the partial vacuum created is lost and the spring seats the valve over all of the air and gas openings until the operation is repeated.

In the modified construction shown in Figs. 5, 6, and 7 all of the essentials of the valve hereinbefore described are retained and only slight alterations are resorted to, and notably the following: The needle-valve is in alinement with the discharge-orifice of the hydrocarbon-channel b, and in this construction the air-feed is controlled by an adjustable cup or funnel D and the registering openings e and f. In this present valve the plug 4, reservechamber 1, and perforations 6 are wholly dispensed with, the plug 4 because the present valve is intended for use with gasolene only, and consequently no reserve-chamber, as 1 in the other construction, is needed, and for the same reason the perforations 6 6 are unnecessary, and in lieu thereof the entire charge of hydrocarbon in the present coustruction finds exit through the hydrocarbonchamber b" at a single point, where it intermingles with air discharging through the perforations g and is further intermingled with a disruptive circular current of air coming in over the outer periphery of the disk c of the valve, as indicated by the arrows. A removable valve-head E affords access to the vacuum -chamber h. Connection with the engine is afforded at the side, as shown in Figs. 5 and 7.

My improved valves are applicable to any form of explosive-engine and would iind a ield of usefulness in the rapidly-growing art of so-called motor-vehicles or automobiles.

It is evident that slight additional changes might be made in addition to those described in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact construction herein set forth; but,
