. specification of Letters Patent. Application and December i901,- semi No. 408,363,-

citizen of the United States, residing at .Scranton, in the county of Lackawanna and .State of Penns lvania, have invented certafn new andguseul Improvements in Carbus peters; and Ido hereby declare the follow-' :ing to be afglhclear," and exact description .of the-fnvent ibn, such as will enable others sk lled'm the art to which it appertains toi makeanduse the same. V

This invention relates to improvements in c arbu'reters, and particularly to improved carbureters ada ted for use with vapor engines orinterna combustion engines, as well as in other places where it is desired to em- ,l iyilirocarbonas fuel.

, The invention compr ses the provision of gasolene, kerosene, or other liquid means for correctly mixing the hydrocarbonw i th ai'r, and for sup lying varying quanti-- ties of either air or ydrocarbon oil under "var ing demands, for the mixture.

he object. in view is the provision of means for maintaining a proper mixture of. hydrocarbon and, air regardless of the amount of mixture demanded.

Another object in view is the automatic- .ally varying the entrance of air and hydro- .carbon for always maintaining a proper mixture automatically undcryarying demands.

.A still further object in view is the provi .s'ion of mechanism that will not require springs and the l1ke for causmg an automatic operation of the air regulating means and oil regulating means. With these otherobjects in view the invention comprises certain novel constructions, combinations, and arrangement of parts as will be hereinafter more fully described and claimed.

In the accompanying drawing: Figure 1 is a vertical section through a carbureterembodying the features of the present invention. Fig. 2 is a section through Fig. 1, on line 22. Fig. 3 is a top plan view of a discharge nozzleor atomizer being shown in connection therewith. Fig. 4 is a vertical section through the atomizer with a slightly modified form of regulating means secured thereto...

It is welllmmm that toobtain the best results and the least expenditure of oil in .engines and thelike, the mixture of'o1l and air must be of the proper proportion, neither too .much nor too little.

viding a structure foraccomplishing this i In addition to prodesirable result the present invention is aimed to provide means whereby the proper mlxtpre of oil and air may be obtained'with varying demands upon the carburetor, at that without any manual adjustment '0. large quantity of oil and air may be drawn from the carbureter, .or a comparatively small amount of air may be drawn from the carbureter, .andj'in either case be properly mixed for burning as" fuel-in any desired wa as, for instance, an internal combustib e engine.

Referring more particularly to the draw-, ing, 1 indicates a mixing chamber which has leadin therefrom a discharge opening 2. ischarge opening 2 has positioned therein a valve or cut-ofi 3 o erated by a handle 4for positioning the va vein any desired position'ior permitting any desired quantity of mixture from mixing chamber 1 .to be drawn out for use. Suitable lug'so'r secin'ingmembers 4 and 5 are provided for securing .the carbureter in position.- Surrounding the lower part of opening 2 and immediately above mixing chamber 1 is a chamber or receptacle 6' having mounted therein a balancing piston 7 provided with relieve passes 8. Receptacle 6 is entirely closed so that as piston 7 operates therein and moves from the top toward the bottom, or vice-versa, the air on one side of the piston must pass through relieve passes ,8. This will prevent piston 7 which may be termed a perforated retarding piston from any sudden or quick movement and also prevent valve 9 from any sudden or quick movement as the same is rigidly connected with piston 7. Any desired number of connecting rods 10 are secured to piston 7 and in turn have secured thereto arms 11, which are firmly riveted or otherwise secured to valve 9 so that anymovement of valve 9 is connnunicated to piston 7, and also any movement, as by law of gravity, of piston 7 is connnunicated to valve 9. Passing through valve 9 and loosely fitting therein is a tube or atomizer casing 12 that is rovided with arm's,13 and 14 which are firm y secured to a tubular extension 15 of mixing chamber 1. By this structure atomizer casinglZ is always held in one position but valve 9 is permitted to reciprocate and is moved according to the amount of mixture required in tlie carbu-.

reter, the valve remaini against the seat or bhttom of mixing chem er 1 when no mixture is require'dand is raised in roportion to the amount of mixture requirec Atomizer casing 12 is also formed with holes or apertures 16 and 17 that are in turn provided with valve members or plugs 18 and 19, the valve-members or lugs 18' and 19 being mounted in the tu ular extension but adapted to be brought into "proximity to holes or apertures 16 and 17, for closing the same and again removed therefrom for. per mitting air to pass therethrough.

Rigidly secured to valve 9 are a plurality of supports or connecting rods or bars 20 and 21 which have secured to their lower ends a cup shaped regulator 22 which is adapted to move upward. and downward with valve 9. The upper part of regulator 22 is open and the lower part closed with the exception of a small opening 23 through which discharge nozzle 24 projects. Discharge nozzle 24, hmvever, does not entirely fill opening 23 so that a certain amount of air may pass there through over the top of nozzle 24 together with air passing from over the top or cup 23 down to the lower en; of atomizer casing 12. ltigidl secured to valve S) is a support 25 that has secured thereto a substantially conical shaped dellcctor or plug 26 that, when in its lower most position, will substantially fill the upper end of atomizer casing 12. This deflector is designed to connningle and also to check the llow of air and liquid through atomizer casing 12 while valve 9 is designed to check and regulate the How of air into ruining chamber 1. air in the tube 23 and also from the top of cup shaped member 22 a draft is supplied for drawing oil from discharge nozzle 24 for carrying the same upward into mixing clunnber 1. This oil and air is usually too rich in oil to be a proper mixture for proper ignition, and conserpiently air is permitted to flow into mixing chamber 1 around valve 9 from air chamber 27. The air passing from chamber 27 through or around valve 9 mixes with the oil laden "passing from the end of atomizer casing 12 and lrom thence passes upward through discharging opening 2, the sucking action l'rmrrthe engine or other device creates a partial 'varuum or tendency toward a vacuum in mixing chamber 1, which causes the air to pass through opening 23 and also air to pa a into mixing chamber 1 around valve 9 and from thence on out, mixing as it goes. .lly this action the air drawn around valve 9 and the oil nozzle 24 is in correct proportimi for forming a proper mixture for ignition. .11 for any reason it is found that there not a sullicicnt draft through the tube ol' atomizer casing 12 to/suck or draw out of discharge nozzle 27 sullicient oil, plug or valve members 18 and 19 are moved toward graduating airways or By the entrance of the drawn from ."alnount of oil fed to mixing chamber 1 apertures 16 and 17 and then the suction from above will draw less air in through these apertures, causing more suction on nozzle, this causing it to deliver additional oil .to the mixing chamber.

Surrounding air chamber 27 is an annular chamber 28 designed to receive oil and to have a certain amount maintained therein at all times, preferably such amount as to bring the upper surface of the oil on an approYimate line with the upper edge 01' the discharge nozzle 21-. Connecting nozzle 24 with annular chamber 28 is a passage way 29. Passage way 29 is formed with an aperture or opening 30. A valve 31 is positionedin passage way 29 for manually regulating the amount of oil passing from annular chamber 2 8 to nozzle 24. By this means the oil fed to discharge nozzle 24: ma; be checked or regulated manually, but ordinarily valve 31 is open fully, for permitting the free flow of oil from chamber to nozzle 24, the automatic operation of valve 9 and the remaining automatic mechanism, regulating the amount of oil used when taken in connect-ion with the amount of suction or draft exerted upon opening 2. Nozzle 2 i nut be secured iri passa e way 2.) in any convenient iuauncras being *rew threaded therein and ha". in connection therewith plug 32 fitted into pas- Q 0 v sage way .29 11! line w th the nozzle so that the same may be easily cleaned out whenever desired.

Mounted in annular chamber 28 is a float 33 of such a weight as to held open valve 34- until the oil in annular chamber 28 has reached a level equal to substantially-the top of nozzle 24,v and then permit the closing of valve 34. A bil'urcatml member 3-5 is pivotally mounted at so at the bottom of chamber 28 and has the bifurcated arms thereof n( irn'=.all resting against the bottom of the annular lloat 33, so that when the oil in annular chamber 2% has reached a predeter mined level weight 257 will close valve 34. it will also be evident that when the oil in chamber 28 has lowered, Heat 33 will be lowered, and consemicntly acting upon UlCIlllWl'Bi'i will raise valve "1 for permitting oil to flow 'l'roin passage an, it) into rhauiher 28, oil

being led from any d sired source to passage way 5%. it will be ooserved that if desired up shaped re; -;ulator 22 may hereriroved and the amount of air passing through atomizer casing 12 'egulated by member 26, tluu gh ordinarily rrirt-or 22 is used for giving a double regulat in Fig. 4 will be seen a siiithtljr modified form of regulating means for regulatingfhn J recap 'urlc39 is },r ,rvl-l.---i ihat is dcsignrd to fmllltl'l lit within the upper cud oi atomizer ca; '11,; 12. Receptacle 2-3.) is provided with ion *itudinal apertures r slots 40 and to be open at one end this figure a producing 'practicallythe same result.

together with a as 41 so that air and oil passing into it through atomizer casing 12'will be permitted to pass out through aperturcs'40 into mixing chamber 1. Receptacle 39 is rigidly secured to supporting member or bracket 42 which acts as a top or cover for the receptacle and also as a support therefor, the support being iirmly secured to valve member 9 for simultaneous movement therewith. In addition to the receptacle 39 another auxiliary regulating cup 43 is provided at the iower end of the atomizer casing 1Z,'wl1ich acts in a similar manner to cup 22. Regulator 43 is also arranged with elongated slots or apertures 44 in a similar manner to regulator 39, or the slots can he made in atomizer casing 12 so arranged as to be made to close as the sleeve or cup 43 moves upward, in which case the openings 44 are not made in 43. It will be evident that'c'up 43 can be made to either go inside or outside of atomizer: casing 12; both In use regulator 39 may be used separately or in conjunction with regulator 44. as may be de-' sired, though ordinarily the use of two regulator's is desirable as the regulation is more even. 7 I In ,0 eration when it gdesiredtomeceive an exp osive mixture from passage way 2ia vacuum or partial vacuum is created by the turning over of the engine "or by ahy other desired means, which will consequently suck or draw air through atomizer casing 12-,

quantity of oil, and in addition will draw air around valve member 9. This air drawn around valve member 9 and the oil laden air drawn thrdugh atomizer c: 12 jrnixes in chamber 1, and from thence passes out passage way 12,. .tobe used as maybe desired. In easlera largeamount oi combustible mixture is desired the suction is com aratively great so that a com )aratively arge amount of oil laden air Wlll be drawn through atomizer casing 12, and a comparatively large amount of air drawn around valve member 9, valve member 9 sing raised from itsseat in proportion to the strengthof the suction. This air and oil for mixing in chamber 1 will pass out through passage May 2. To prevent any sudden 6r unusually quick action of valve member 9 or the too quickly drawing ,oil from nozzle 24, a check or damping member, as piston 17, is provided. Any tendency that valve 9 has to rise will be dampened by piston 7, but will not be prevented, and also piston T will by its ht give continued tendency to close 9, so as not to let an undesirable iount i air'in the chamber '1. By this construction and arrangeme'nt proper mixof oil and airis rovided during arying d lands on the car ureter, so that when a womparatively small amount of mixture is aiiei'l a comparatively smafl amount will delivered, and that in proper ortion.

When a larger amount is desired a larger amount will be dclivercd,and also delivered in the proper proportion, by reason of the relative action of the drawing of oil from nozzle 24 through atomizer casing 12, and the drawing of air around valve 9, Any'de sired number of binding or connecting bolts may be provided for holding the various chambers and parts together.
