GAS-MIXING VALVE FOR, EXliPLOSIVE-ENGINES.

Specification of Letters Patent.

Patented Dec. 3, 1912.

Application filed January 4, 1912. Serial No. 669,382.

To all 'LU/LOWL it may concern Be it known that I, AooLri-i Brenna, a

citizen of the United States of America, and

resident of Wheeling, county of Ohio, and

State of \Vest Virginia, have invented certain new and useful Improvements in Gas Mixing Valves for Explosive-Engines, of

ers, and specifically to a combined gas mixing valve and gasolene carbureter.

The primary object of the-invention is to provide an integral structure for use in connection with internal combustion engines, which shall have the dual functions of mixing natural or artificial gas as an explosive .proper explosive mixture from either an aeriform gas or a'liquid gas.

Another object is to provide a device of the character mentioned for use on automobiles or other wheeled vehicles wherein an in ternal combustion engine is employed as a source of motive power,whieh adapted to feed to the engine, in properlymixed explosive charges, gas supplied from a gas storage tank, or to feed properly carburcted charges from a gasolene erotlier liquid fuel supply. I

\Vith these and other objects in view, the invention "resides in the features of construeti .=n, arrangement of parts and combinations of elementswhich will hereinafter be exel'nplified, reference being had to the accompanying drawings, forming a part of this specificatiim, in which Figure 1 is atop plan view of the invention; Fig. 2 is a side elevation of the same; Fig. 3 is a vertical section on the line 3-3, Fig. 1; Fig. 4 is a horizontal section on the line 4-4. Fig. 2; and Fig. 5 is a similar section on the line 5 5, Fig. 2.

Referring to said drawings, in which like designating characters distinguish like parts throughout the several viewsl indicates a casing in which is provided a mixing chamber 2 to which the gas or gasolene, according as one or the other is employed as fuel, is admitted and prepared for furnishing explosive charges to an engine cylinder or cylinders. Said casing is of substantially upright cylindrical form and has its upper end flanged, as,shown at 3, for attachment to the usual intake pipe or. manifold of an internal combustion engine. The lower end of said casing is open and has mounted therein a valve 4 whereby the admission of air to the mixing chamber 2 for mixing with the. gasolene is controlled. Located in theupper end of the mixing chamber is a throttle valve 5 adapted to be manually operatedfrom the car-operators position in the usual manner, as by a series of suitably connected levers including a lever B mounted upon the projecting end of a rotary spindle 7 upon which said throttle valve is carried. For limiting the extent of closing movement of said throttle valve an outwardly projecting lug 8 carried by the casing has a set-screw 9 projected therethrough, constituting an adjustable stop for the lever (3.

Partially encircling the casing l is a reservoir 10 to which gasolene is supplied through a pipe 11 from a suitable reservoir or source of supply. Gasolene fromthe reservoir it passes by gravity through a passage 12 in the casing wall and is admitted to the mixing chamber near the lower end of the latter through a port 13 controlled by an adjustable needle valve 14.

The valve 4t at the lower end of the mixing chamber is normally maintained closed by a compression spring 15 mounted on a stem 10 to which the valve is attached, sa d spring being interposed between a fixed. pl rt or member, as 17, and a head 18 carried by the outer end of said stem.

Carried by the casing l is a laterally directed arm through which le-tuls a p-...ssage 15) opening into the mixing chamber at a point below the position 'of the throttle valve 5, said mssage having eomnulnication at its opposite end with a gas chamber 20 formed within a casin 21 integral with said arm 40, said gas ehan'iber being adapted for receiving natural or artificial gas through a pipe 22 leading from a source of supply, admision of said gas being controlled by a suitably mounted valve 23.

'gage'ment with the inner face of the head Said valve is normally maintained closed against the pressure of the gas admitted through said pipe by a compression spring 24 which has one end seated against the face of the valve and whose tension is regulated by an adjusti'ng screw 25 projected through a removable cap 26 fitted in the end of the casing 21 in a position facing said valve.

Leading into the mixing chamber 2 at a point below the gas passage 19 is a large air inlet passage 27 controlled bya valve QSwhich is normally held open, as by a retractile coil spring 29 interposed between a fixed portion or member 30 and a head 31 carried on the outer end of the stem 32 on which said valve 28 is carried. Suitable means are employed whereby said valve 28 may be seated for closing off the air supply through said passage 27, as when the gas supply to the gas'chamber 20 is shut off and gasolene is being used, the air suppl 1 for the gasolene being admitted through the lower valve-closed end of the mixing chamber 2. The means herein depicted for closing the air passage 27 is butone of various means which might be employed, the same comprising a yoke 33 disposed in straddling relation to the valve stem 32 and having an inclined face or edge in sliding onof said stem. Said yoke has a stem slidably mounted in a guide member and'is adapted to be shifted forward and retracted by any appropriate means for actuating the valve 28' to move respectively to closed and open positions.

In practice, ither gas or gasolenc may be directed through the device, the former beingthoroughly mixed with air for producing a proper explosive mixture, and the latter being vaporized and properly mixed for producing such mixture without the employment of either a spray or a float feed, as hereinbefore indicated.

When gas is employed for fuel, the gasolene supply to the auxiliary reservoir 10 is cut off and the valve 28 controlling the admission of air through the air passage 27 is opened to freely admit a current of air theretln-ough, which current is induced by the suction. of the engi ;e. The suction produced by the engine pistons and acting on the mixing CllflllllIJGl Qthrcugh the intake manifold is regulated by manipulatioi'i of the-throttle valve and'this suction acts to elevate thevalve 253 for admitting gas -to the gas chamber, the extent of opening of said valve, and, consequently, the relative size of the admitted charge, being dc pendent upon the extent of opening of the throttle valve, as also the amount of air drawn through the passage 27 for mixing with the gas.

lVhen gasolene is the fuel employed, the

gas supply through the pipe 22 is shut oil. and the valve 28 controlling the admission of air through the passage 27 is caused to seat for closing said passage. The su'ction of the engine acting directly upon the gasolene, as'the latter gravitates to the port 13, draws a supply of gasolene into the mixing chamber, the volume of which is regulated by the degree of suction which the throttle valve permits to be induced within said chamber; and said suction acting upon the valve 4, elevates said valve with'each engine pulsation a distance commensurate with the amountv of suction acting Within said chamber. Thus, a relatively large supply of air is admitted with the gasolene to the mixing chamber whereby proper carlun'etion may be effected in. the passage of the mixture through the mixing chamber.

A pet cock 36 is preferably provided in the casing 31 through which gas contained in the gas chamber 20 may be exhausted when such exhaust is desirable. Also provided at a suitable point, as in the cap 96, is a pin 37, normally held by a spring 38 in an elevated position, which is adapted to be depressed into bearing contact with the face of the valve 23 whereby the latter may be held seated, as when gas is the fuel used and it is desired to have the contained in the chamber 20 exhausted prior to taking in a fresh charge.

A small tubular opening 39 preferably provided in the side of the casing 1 allowing free communication between the mixing chamber and the atmosphere, said passage servii'ig as a relief passage tln-ough which exhaust of any back-firingcharge in the device is pin-united.

Having thus described my invention, whatclaim as new, and desire to secure by Letters Patent, is i 1,.
