Applicationled May 15, 1911. Serial No. 627,109.

the count-y of Cook and State of Illinois,

have invented certain new and useful Improvements lin Carbureters, of which the following -is'fa specification.

This invention relates to im rovements m carbureters of the gravityeed or oatvalve ty e, for hydrocarbon or explosion engines l"o -various kinds, but more particularly for asolene engines used for operating automobi esv and motor boats, and it consists in certainpeouliari'ties of the construction, -novel arrangement'iand o eration of the variousA arts thereof as lwi be hereinafter more fnl y set. forth and speclically claimed. 'Tliefmain object of this `inventionis-to r provide av carbureter of simple, eiiicient, and

fles'irabl@constructionin which the mixture of air and hydrocarbon is effected in a most thorough andv satisfactory-manner,and coacting supplemental air-supply valves auto- 4matically[controlled bythe passage of airA through' the lcarbureter;'to' t e engine` are used, to re ulate'the supply of 'air so that itl and theliydrocarbon will be commingled in the proper proportions constantly-'and different' suctions,'-and varying speeds of'the'engine, to the end, lthat a ractlcally constant explosive mixture wil be furnished at all times, unless it is desired to decrease or increase the richness of the mixture, means for which is rovided.

Another object is to provlde means for atomizing the hydrocarbon, and break up the volume of air, as they, assrinto the carbureting chamber, as we as,l to furnish means to heat and expand said elements while within said chamber.

Various other ob'ects and advantages of the invention will e disclosed in the subjoined description and explanation.

In order to enable others skilled in the art to which the invention pertains, to make and use the same I will now proceed to describe it'referring to the accompanying drawings in which- Figure I1,7 is a centralvertical sectional view'through a carbureter embodying the invention." Fig. 2, is a -view partly in section and partly vinelevation `taken on line 2 2 o Fig. 3,'1ooking in the direction indicated "by the arrows. Fig.` 8, is a view in side jthe mechanism for regulating fer to li portions of the elevation of the carbureter casing showing the discharge of hydrocarbon into the car ureting chamber and the outlet of the mixture therefrom, and Fig. 4, is a detached perspective View of the hydrocarbon distributer or atomizer.

Corresponding numerals of reference rete parts throughout the different views of the drawings.

The reference numeral 10, designates a reservoir for the liquid hydrocarbon, such as gasolene, which reservoir is mounted on and has communication through an inlet 11 with a conduit 12, leading from a source ot supply, not shown, to the carbureter casing.

yThe outlet 11, is controlled by a valve 13,

on the Vertical stem of which is mounted a float 14, within the rece taele 10, the arrangement being deslgne to maintain substantially constant level of the liquid hydrocarbon in the reservoir. TThe lower portion 'of the conduit 12, is provided with a drain cock 15, which communicates with the passage 11, of the reservoir, and the discharging end of said conduit is furnished with a band or ring 16, which may be rotatably but snugly fitted on a cylindrical extension 17,

llower and upper parts 18 and 19, respectively, each of which is hollow and have on their adjacent surfaces fianges 20, through suitable o enings in which are inserted bolts 2l, used gor securing the two parts of the casing together. As shown, the upper part 19, is surrounded by a jacket 22, which is preferably in screw engagement at its upper and lower ends with the upper and lower art 19, ot the carbureter casing. This jac :et is provided in its lower portion with an inlet 23, to which a conduit, not shown, leading from a supply of hotI water may be connected, and has in its upper portion an outlet 24, for the discharge of water.

The part 19, of the casing is provided with an extension or conduit 25 for the outlet o the mixture of air and hydrocarbon, which conduit has communication with the engine, not shown, and may be connected thereto in any suitable manner. Extended across the upper part 19, ot thc carbureter casing, the interior of which part forms the carburet-ing chambe As before stated, the lower part 18, ofv

the casing isprovided witha downward extension 17 which isjprovided in its upper portion with a cavity27, with l,which a number of openinge`29,`*lcading from the said extension communicate and are'uscd for the admission of a con.-A stant supply of air to the casing.-.fTheexten sion 17, is provided with a central bore 30, the upper portion-of which lis enlarged andY i screw-threaded to receive a nozzlel, which nozzle is formed internally. at .its upper end` withja tapered valve seat 32, for a valve 33, which haasits upperend vtaperedffto corre spond withl itslseat,and is located within the f bore 30, of the extension 17, as well as within `ently ex lainecL;

provided wit a, circumferentiall roove 35,-

and withv a port or channel 36, w iichcommunicates at'its inner end with a'poi'tf?, formed in the lower portion of the nozzlel 31, or needle valv,ecasing., The outerend ofthe porter channel .,36, communicates with the groove 35, and when the rinfr.16,of the conduit 12, is in positionon saidD extension it is evident that' said port or channel will communicate with tho channel of said conduit through the groove 35, no matter what direction said conduit may projectl from said extension. The band 16, of the conduit 12, is held in position on the extension 17, by means of a nut 38, which engages its lower portion, thus it will beseen that the conduit 12, may be turned 0n the extension 17, so that the reservoir 10, may be laced at any desired oint., Mounted ont e lower portion of tie extension 17, .is a` cu 39, which can be used for catchin and iiolding the drippings fromthe car ureter casing. Reciprocatingly mounted in suitable apcrtured projections 40 and 41, on the sides of the part.f18,"of the casing, andthe jacket 22, res ectively, is,y an` operatinn' rod 42, for the va ve 33,:which controls thesulpplyof l'ydrocarbon. to the: carburetin clamber.

his rod is preferably formed o `two piecesy 43Y and A4 whichA are screwed' together at, their f meeting., yvenda and the 'latten yhas its assages 26, communicate at each of their` lowerort-ion vscrew-tlireaded and lhas mounte 4thereon al nut 45,'to regulate the upwardiiiovementof said rod. The upper v'portionfgof the member 43, of the operating 'rod lieprovided with a flange or projection 46, .against which one end of a spring'47, lwhich enfi'cles said member rests, the other endof the spring resting againstthe bottom of the 'cavity 48, formed in the projection 41 of tliejaoket `of ,thecasing The upper end of the member 43, of the oierating rod is lbeveled so as to co-act wit an adjusting screwf49, which is seated in a shaft 50, journaledtransversely in the extension 25, leading from the car ureting chamber. Mounted on the shaft 50, is a-damper or valve 51, used for regulating the passage of, ex losive mixture from the cai'buretiiifr cham ei' to the engine. Fixed on the shait 50, is a lever 52,- which may be suitably' connected to a lever, not shown, on the machine used for regulating the carbureted air to the engine. Secured to thelower portion of the valve operating rod is one end of an arm' 53, the 'otherend of which is adjustably connected tothe lower portion of the needle valve 33, wliichmay have'on its lower end a head 54, bymeans of` whiclrit may :be turned so as `to adjust it with respect to the arm 53, and

its operating rod.

Located within the lower portion 18, of the carburetor casing and resting at one of its ende on the rim of the cavity 27, in the extension 17, is a conduit 55, which is preferably circular .in shape and contracted between its-,ends, the upper end of which rests againsttlie lower portion of the upper part l19, of the carbureter casing as is clearly shown infFige.4 1 and 2, of the drawings. The' upper portion of the memberjor conduit 55,\is provided with a. series of openings 5G, wliichfurniah passageways for nir from the supplemental supply-valve casing 57, which extends laterally from the part. 18, oi the carburetervcasng and is in comuuiuication therewith. Loosely mounted in the upper tapered portion of the conduit 55, is a goed lene or hydrocarbon distributor and atomizer 58, which is in the form of a downwardly-tapered cup having on its outer `surface a series of circumferential steps 59, and alseries of upwardly extended grooves (50, which latter, will allow fluids to pass from the lower portion of the conduit 55, into the carbureting chamber when the distributor is in its normal position as' shown in Fig. 1, of the drawings, in which position it will be understood that/the lower portion of said distributor will rest on the run of the cavity 34, of the nozzle 31, or needle valve casing. In the o erationot` the engine the distributor 57, will e raised by reason of suction ao as to permit gasolene or hydrocarbon as it ia dischar ed from they valvel casin 31, to strike t e lower surface of the distributer mesme* 59, as is' obvious.' Thedistributerl 57, isrestricted in its upward movement b vmeans of one or more pins ,61, with which t ie inner surface offthe upper portion of the conduit t 55, is provided. Fitted-in a suitable opening in the upper portion of the supplement-al air-supply valve casing is a plug 62, which is provided with openings 63, for the admissionof. air.,to,thesaid-casing, and said plug `has on its lower surfaces. seatI 64,'for a valve tion 69, thereon.

65, which has a central opcning66, opened and closed by,means-of another valve 67, the 'stem 68, of which latter valve is extended througlrthe' plug 62, and a tubular projec- Adjustably mounted on thevalve stem 68, is a sleeve 70, which surrounds the projection 69. Surrounding the stem 68, and resting at one of its ends against the upper inner surface of the sleeve r 70,'and atits otherfend against the bottom of. the projection; 69, Yiszaicoil sprin 71, which will normally hold the valve-67, in its seated position,yet will permit said valve to open-when the suction throuah the carbureter is sufiicient therefor. The valve 65, is

provided on its'lower-surface with a yoke.-l 72, which is .provided with upward projec-f tions73,-theends,0fv;which are located a slieht distance below the valve 67, which-y `va ve is adapted'to contact with said pro,-4

jections and to cause thevalve` 65, to be pressed. downwardly vwhen the suction through the. carbureter is increased to a suiiicientextent. Extending downwardly from'the yoke 72, isxa sleeve 74,'whichis loosely fittedon a stem 75, having an enlargement 76, which-is loosely `fitted ina tubularrojection'77, which projects downwardlv rom the valve casing 5751, and is externally screw-threaded. Engaging the screw-threaded pi'o 'cctioii 77, is a cap 78, which is used for adjusting the stem 75, for it is apparent that by turning thecap in the proper direction said stem will be raised or lowered, in which position it may be held by means of aspiing actuated pin 7 9, located in a depending arm 80, on the lower portion of the valve casing 57, for the supplemental air-supply valves. Surrounding the sleeve 74, and the stem 75, is a spring 81, which rests at one of its ends against the yoke 72, and at its other end against the upper portion of the enlargement 76, on said stem. The tension of this spring is regulated by turning the cap 7 8 in the proper direction.

The operation' of' the device is as follows. Hydrocarbon is supplied from the source of supply and through the reservoir or iioatva ve chamber 10, conduit 12, passages 36 and 87, and needle valve easing 31to the entrance' .ofjthc carbureting chamber, through the'suction or operation of the engine,' the vdistributor 57, will be slightly ri'aised,tlius permitting the hydrocarbon to l,be-spread thereby and to pass around the same into the carburcting chamber formed by the upper part 19, of the carbiireter casing. In this action the hydrocarbon will he lbroken up or atomizcd by means of the steps or baflles 59, of the distributer, and atthe same time air will be drawn through `thciopcnings 29, in the extension 17, of the lower part of the carburetor casing, but as the suction increases a supplemental supply of air will be admitted to the valve casing through the openings 63, in the plug 62, and the opening 66, in the valve 65, from which casing it-will pass through the openings 56, in the conduit 55, and be mixed with the hydrocarbon iii the carburcting chamber. vWhen the suction of the engine is further increased the valve 67, acting on the projections 7 3, of the yoke 72, will force the 4valve 65, downwardly thus permitting a furthersupplemental supply of air to the -valve casing 57, from whence'itwill pass from the openings 56, into the carbureting chamber. By employing the jacket 22, around the portion 19, of the carbureter casing'and supplying the latter with the passagcways or tubes26, it is evident that hot water-or other heating agent maybe forced through saidl tubes or passageways and around the carbureting chamber, thus raising the temperature of the air and hydrocarbon, and thereby causing them to be intimately arid most thoroughly mixed. By moving the lever 52, in the proper direction, it is eyidentthatthe ,valve 51, will be turned so yas -to `regulate the quantity of v.explosive mixture to the engine, and also that the needle valve 33, will be adjusted through the instrumentality of the operating rod-42, adjusting screw 4), and arm 58, so as to regulate the quantity of hydrocarbon supplied to the entrance opening of the carbureting chamber.
