To all whom t may concern.' I

Be it known that-I, Emmi: B. Kanar, a

-ci-tizen .of the United States, residing. at

combustion engines, the invention having reference more particularly to improved means for feeding and 'atomizing the liquid hydro-carbon and mixing it with air.l i

The object of the invention tti-'provide an 'improved' carbureter of simple construetion that will be adapted to be produced at relatively small cost, and be` so constructed l as' to be highly eiiicient and economical in the-use of the hydroicarbon in the explosive mixture; a further object being to providea carbureter that will be so 'constructed that the 'various parts thereof can be readilyjadjusted, 'or taken apart for the. purpose of cleaning' the apparatus; a still further object being to provide a carbureter that will be adapted to be repaired incase of accidental damage thereto without discarding parts that may escape damage.

The invention consists in a. carburetor of novel construction comprising primary feeding and atomizingapparatus, and adjustable detachable auxiliary" feeding and atomizing apparatms;` and the invention consists further in the novel parts, and the,

combinations and arrangements of .parts, as

hereinafter particularlydescribed and claimed. -z

Referring to the drawings, Figure 1 is a -vertical central sectional view of the improved carbureter as preferably .constructed; Fi 2 a horizontal section on the line A. A ing. 1; Fig. 3 a' horizontal section on the line B B in Fig. 1 inverted, the

iioat in the-reservoir being omitted; Fig. 4.

a section on the line C C in Fig. 1 omitting the fuel feed-valve and the float; Fig. 5 a fragmentary section reproducing portions of Fig. 1 on an enlarged scale, and Fig. 6 a portion of Fig. 1 reproduced on. an enlarged scale.'

A suitable lever 18-is mounted .on a pivot 19 in the valve-chest and extends into the interior ofthereservoir-and has .an annular float QO'secured thereon, the lever extending beyond the pivot and having an end 21- 4suit- 'and approximately U-shaped with its ends extending upwardly, an 1n,let-end section 24 being connected to one end, and-:an outlet end section 24 beingconnected to the ,othercnd ofthe section 24. The lowermost portion 'of the mixing .tube'is central on 'the cover 22 and atube Q5 is cast inteably connected with the stem 16'so `as to which is seated grally on the central portion of the cover at the under side thereof, and it' extends through theinterior" of thc reservoir and through thelfl'oatand the bottom 1, the -tube having collar .26 formed thereon' that is seated upon the. bottom, the projecting end portion 27 of the tube having a nut QS screwed onto it and against thcfuudcr side,

of. the bottom. ."heaniddle and lower portion of the' tubo 1s somewhat largcrin iamcter'internally than the upper cud por- .orrr-there beinga tapering 'portion Q9 somewhat below the 'upper ten-.l ol' the tube,

uppoi'ted uprightly in and 33v th '.4 communication'lbetween the: interior vof the' reservoir andfthe'interior of thetubel,-` the upper end of the tube 31 having a spraying. nozzle -34 thereon arrangedwith. its orifice-` uppermost at a suitable distance below thev entrance to the relativelyzsmaller bore 3()` of the vtube-25. .The tube 31'projects downwardbelow theendofthetube-Q and has exterj'nal screw-threads 35 thereon to which a vpacking-nut 36 is connected', the tube 31 havlng also 'internal screw-threads 37.v A valvestem 3 8\is inserted through the packingTnut and into the tube 31 and has screwthreads '39 thereonin. contact with the screw-threads 37, the stemhaving a relatively smaller inner end, portion 40 on the end of which is a the tapering portion 29 'and needleepoint valve 41 adapted to fbe' seated at the inner side ofthe orifice of the-nozzle 34, for varying the'area ofthe 'orifice and for assisting in atomizing the h drcarbon, 4 e relatively smaller portion'30 of the interiorof the. tube aisting alsoin thefatoinizing'operationa as does also the nozzle 34' 'as the air-fis drawn upward throughthe tube '25 and 'sucks lt-he hydro-'carbon past the valve 41 andout' of the nozzle 34, the structure within the reservoir constituting the'- primary feeding' 'and atomizing or carbureting apparatus.`

. A valve-chest 42 is cast'inte 4lly with the mixing tube secti`on'24'` and il; a bushing 43 screwed adjustably into' the, under' Side lthereof ina suitable opening, an air-inlet valve 44 being'removably seated fupo'n the upper or inner end of the bushing and provided with a guide stem "45 that v1s movable in a hollow guide 46 adjustably supported in the top of the valve-chest, a spring 47 being seated upon the valve and aoamst the inner en d of the guide for nrmallby holding the valve to its seat, the valve being adapted to be' opened only-'atf'relatively high speeds ofthe engine, as an auxiliary valve for admitti an l increased .of air or carburet airitothe tube.

In order that thdrilmitted by the 'auxiliary air valve may be more highly carbureted than would be possible by means .of the fuel feedingapparatus, a suitable valve'fchest .4 8is provided which has a tube'ivst ion one side thereof and'adapted the bosses on the `side of the reservoir, the tube A'as illustratedfbein screwed into the boss4, and as will lbe un erstoodz in case. the: valve-chest 3 interferes -with`existingconstruction of vthe engine. or other machlnery, the reservoir 4may be turned so as to 'move the valve-chest e" in 'respectively that afford -34, is fed out of the `way and the cover 22 adjusted ac- V and.;either one of the-plugs 1 0 ay V'beifefino'ved. and the tube 49 inserted-in its', @16Std With Plug- .Y a packing-,box 50 on? is a packing-gland 'L--i-'Atube 52is inserted cordinl and llgri y yplace,"the boss4'then being itsupper end .in Whichthroxgh 'the' glandA and screwed adjustably into the valve-chest`48..beyond .the bottom i of. the4 packing-box, :the 52 having .a spraying nozz e 53 'on its upper end which preferably has sockets54 therein to receive a suitable tool for turning the tube so as to lraise or lower it. The upper portion of the tube 52h35 external screw-threads 55 vthere#` on on'which a dish-shaped deiector 56is adjustably screwed, so that it may be raised or lowered with respectv to the nozzle and is prevented -froni v accidental movement by lmeans of a lock-nut 57 screwed onto the tube against the delector. The deflector is somewhat larger in diameter'- thanthe interior of the bushing 43h-nd is arranged at a suitable distance below the bushing. The lowerrportion of the valvechest 48` has an extension58- thereon which has screw threads 59 therein,

-a packing-nut'4 60 being placed on the end portion of the extension. Ava-Ivestem 61 is inserted through the packing-,nut and has screw threads 62 thereon in contact with the screw threads 59, the valve stern extending .o he valve-chest 48has` up through the tube 52 and having a needlepointvalve 63 on its upper end extending into the orifice of fthe nozzle 53, for varyingthe area of the orifice and coperating with the'nozzle to assist in atomizing the hydrocarbon which may be' drawn from the reservoir by the higher velocity of the air enterinfr 'the auxiliary air valve, the dish-shaped de ector serving to create partial vacuum at the nozzle 53, so that the air passing between .the deflector andthe lower end of the bushing 43 when entering the'bushing'will the more effectually suck up' the hydro-carbon, the valve 44 assisting also in atomizing the liquidl as it passes with the air into the'mixtube. The outlet end 64 of the mixing tube 'section 24" is suitably adapted'to be connected withfan explosive engine, or a pipe leading thereto. The section 24 has a rock shaft 65 mounted therein to which a butterfly valve 66 is secured, the" shaft having an operating arm-67 thereon.

In practical use',v while the engine is being started and when running lat relatively slow speed, the hydro-carbon which is maintained at the desired -level in the" reservoir by means of the float therein, approximately ai) the level of the top of the nozzle y means of the valve 41 and taken up and atomized in the tube 25 byV means of the air passing through the tube into the mlxingtube section 24 from which the carbureted air is drawn through the tube section 24 *into the engine cylinders. `When the suction increases due to increasing speed of the engine, the" auxiliary ,.valve 44 is -brought intoaction and the air drawn in at higher velocity draws the hydro-carbon from the nozzle 53 asbefore explained, so' that the auxiliary, `Feeding is automatically brought into action as required by the engine, and its action discontinued automatically when the engine is again reduced in speed below the normal rate. It Vwill be understood that the top of the nozzle 53 is slightly higher than justable nozzle that is below-the open bottom flector supported on the nozzle, and a valve in the nozzle.
