ILLINOIS- y ofthe UnitedStates, residing at Chicago, in the countyof Cook andl State of Illinois, have invented certain new and useful Imf proif'ements in Carbureters, of which the l ments. in carbureters for explosion or hydro carbon' enginesof various types for' various purposes,fbut more particularly for gasolene Venginesrfor operating 'automobiles and inoitorfboats; and it consists incertain peculiarities of the construction, novel` arrangement andoperationof the various parts thereof, as 'will be hereinafter more fully set forth and specificallyclaimed.v i

The principal` objects of the invention are to `simplify the construction of such car-` bureters; to improve their general efficiency; andto provide earbureters which .shall be compact in forni, simple,V and of such construction as to provide means to adjust and maintain during its operation the proper proportions ofair andhydrocarbon admitted thereto, also to introduce the air to the, "carbureter so as to produce more thorough and complete mixture than Ais ordinarily donezfl to provide automatic means for the admission of lair to the carbureter in propel' proportions coiistantly1-` and under" different suctionsof the engine.l Various other o bjects and advantages of the invention will.

A f' Like numerals of reference refertoieorresponding `parts throughout `the .different views of the drawings.

`T he casing ofthe carb-ureter is pre-ferably.`

formed of upper and lower parts ltlfa'nd `1l, respectiyely, which` are hollow and have meeting flanges 1Q, and 13, on theii; lower and upper portions respectively, which:

flanges may be secured together by bolts 15,

extended through suitable openings therein.` The upper portion 10. of the casing, is provided with an extension or conduit 16for the outlet of the mixture ofair and hydrocarbon, which etension or conduit has coininunicationwwith the engine (not shown),- and `may be connected thereto in any fsuitable manner.' Located within the part 10, :but spacedtherefrom,,is a receptacle 17, forthe retention and circulation of hot water, whiohf may be supplied.v thereto througha conduit 1Q, in the lower portions of1 the parts 10and 1T, and Vmay be discharged through a conduit 19, in said parts. preferably at a pointabove the `inlet conduit. In `the present instance, the part-10, of the casing. and' thereceptacle 1T, therein, as well asihe conduits 18,7and

19. are shown as being lformed integrally with one another, but .it obvious that they nia'y be separate parts but located with` re` i i' PateiitedMai'r-, 1912. Application filed October24 1910. Serial No. 588,834. i i .l

`for the upward 'passage ofihyd'rocarbon and gscrew-threaded and hasadjustably mounted eid in place on the stem 23, by means of a nut2 6, on the lower portion of said stem.

The-fcollar 25 is provided with a recess 27, vwhich may' extend around said collar and is for the part 1,1, of the casing, may rest.

air regulating band is provided with 'an ex-l the reception of thenner end of an adjusting screw 28, which is horizontally located in a suitable opening formed in the lower portions of the-casing 10, and receptacle 17, as -is clearly shown in Figs. 1, and 2, of the drawings. Surrounding the valve stem 23, and resting at one of its ends against the upper portion of the collar 25, and at its other end against'the partition 22, is a spring 29, which actuates the needle valve in one direction. Mounted on the upper-.end of the valve stem 23, is a head 30, which has at its upper end a laterally disposed. projection 31, between which and the lower portion of said he'ad, is formed a transverse recess 32, Vfor an eccentric 33, which is fixed on a shaft 34,

which shaft is horizontally and transversely' journaled in the upper portion of the part 10, o'f the casing. v The lower part 11 of the casing, is provided at its lower end with a'series of openings 35, for the admission of air, and is` preferably provided on its inner surface with an inwardlyv extending annular-flange 36, located just above said openings, against the lower surface of which flange, a band 37, having a series of openings 38, which may be brought to register with the openings S''hin 1s tension 39, which projects through a suitable opening or slot inthe wall of the part 1 0, by

means of which projection the said band or regulator may be turned so as to cause the openings 38, therein to register with the vopenings 35, in the casing, or when desired,

to throw the samevout of register. Secured on the lower end of the part 11, is a plate 40, on which the lower surface ofthe regulator 37, will rest. The `upper portion of the part 11, is provided on its inner surface with a valve seat 41 for the valve 42, for the from the wall of the part'11, and then upi carbureting chamher. Extended inwardly wardly and centrally therein, is an extension 43, the upper portion of which is providedwith a socket 44, in which is fitted a plug 45, having a channel or port 46, therethrough, and provided at lts upper end with a tapered valve seat 47, ,for the tapered end of the needle valve 24, which co-acts with said seat to regulate the flow of hydrocarbon through the opening in' said plug. The ex? -tension 43, is rovidedwith ar channel 48, which communicates at oneof its ends. with the channel 46, in thesaid plug and at its other endwith thechannel 49,0f a .pipe 50,

which may be suitably secured in an opening fumano 51, formed in the part 11, ai the casing.

T hebuter p ortion of the pipe of connection 50, is provided with an upward extension 52, .which has a' valve chamber 53, for a float operated v alve 54, which is seated in the ,upperI portionof said. chamber. The.

llower part ofthe chamber 53, is provided with a drain-cock 55, and the upper part of the extension 52, has mounted thereon a're.

ceptacle 56, which has communication withl the channel 49, and valve chamber 53, as

shown in Fig. 1, and Said vessel or receptacle has mounted on its upper end'a cover 57, which is provided with a vent opening` 58, and a central opening 59, through which the upper portion of the valve stem 60, is

extended. This stem has mounted thereon withln the vessel 56, a float '61, to lactuate the valve 54, on the lower end of said stem.

The pipe' or connection 50, has communication at its outer end with a'supply of hydrocarbon, not shown.

Mounted on the upper end of the extension 43, is an air dlstributer 62, which `is provided with a series yof upwardly tapered openings 63, which communicate at their 'upper .ends with the carbureting chamberl around the plug-45, so that thev air passing through said openi-ngs will comminglewith the hydrocarbon asit is discharged through.

the discharge portA or channel 46, in said plug. The valve 42 for the carbureting chamber is provided with a peripheral flange 64, which is. upwardly and outwardly inclined, to correspondv lwith the inclination 'of the seat 41, for said valve, and -is provided wit-h a series of openings 65, which are inwardly directed as 1s clearly' shown in Figs. 1, and 4, ofthe drawings. At its cen. tral portion, the valve 42, is provided withV a hollow'depending extension 66, in the uper poiftion of which the airl distributor 6,2,

1s located. The lower part of the extension 66, is providedl with openings 67, for lthe passage' of 'air from ,t 1e air chamber 68, which is formed by the lower part 11, of the casing." Gommumcating-4 at one of its ends with theair chamber 68,.is an air inlet pipe 69, which'has its outer portion downturnd and lcrew-threaded to, engage a cap 70, whichis provided Awith a series of openings 71, 72, and 73, preferably of different sizes. These openings are governed by ball valves 74, 75, and 7 6, respectively, which balls ai'e referably of diiferent sizes andare guarded hy means of arches 77, located directly over said valvesand mounted on a foraminous member'v or .plate 78, in screw-engagement with the inneru per surfacefof the cap 70.
