To all whom it may concern:

Be it known that I, EDWARD J. Pnomii., a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Carbureteis; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as vwill enable others skilled in the art to which it appertains to make and use the saine, reference being had to tlieaccompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention has reference, generally, to improvements in carbureters for internal combustion engines; and, the presentinvention has for its principal object to provide a novel and simply' constructed apparatus or device in which a perfect admixture of the vgasolene with'air is obtained to produce the explosive gas which is to be passed into the cylinders of the internal combustion engine.

The invention has for its further object to provide a means for eiciently atomizing' the gasolene so that the same may lie-quickly and thoroughly mixed with theinrushing air taken into the mixing chamber of the carbureter.

A further object of the present invention' means for feeding the gasolene into the mixing chamber of the carburetor, the parts of whichL are reduced to the greatest simplicit in construction, to produce not only `an e ficient gasolene feed, but also a gasolene feed of much higher eiiicie'ncy than that of'the old styles of gasolene feedsmechanism.

- Other objects of this invention'not at this time more particularly enumerated,.will be clearly evident from the following detailed4 description of the same.

With the various objcctsof the present in- Ventron 1n View, the said invention consists, primarily, in the novel-carbui'eter for iii-A lternal combustion engines. hereinafter set forth; and, furthermore, thisinvention consists in the novel arrangements and combina tions of the Various devices and parts, as well as in the details of the construction of the same, all of which will be presently more fully described, and then finally embodied in the clauses of the claim which are appended t0 and which form an essential partv of this specification.

The invention is clearly illustrated in the accompanying drawings, in which :-4

Figure 1 is a transverse Vertical section-of a carbureter, embodying the principles of the present invention, said section being i taken on line l-1 in'Fig. 2, looking in the direction of the arrow ai; Fig. 2 is a Vertical section taken on line 2 2 in said Fig. 3, looking in the direction of the arrow y; F ig. 3 is a detail View of the air-inlet end of the mixing chamber of said carbureter, the same being shown with the throttle-lever so adjusted that the throttle opens the passage or inlet for the entrance of air into said mixing chamber; Fig. 4 is a view similar to' that shownin Fig. 3, except that here the throttle is adjusted so as toclose the air-inlet leading cal section taken on line 5 -5 inl said Fig. 2, looking in the direction of the arrow with y certain! parts of the-mechanism omitted, the same illustrating the throttle-member in its opened position, which permits an influx of gasolene into the mixin ychamber as the air .passes'th'ereintog and, *i 6 is a view similar ,to that shown in Figay 5, with the exception that the throttle-member is shown in its closed relation, thus closing the gasolene feed mechanism simultaneously with the closing of the air-inlet of said mixing 'chamber.

Similarcharacters of reference are employed in all of the herein-above described views to-indicate` corresponding parts. Y, Referring now to the said drawings, the referencecharacter 1 indicates the complete form of carbureter made according to and embodyin lthe principlesiof the-'present invention, t esaine com rising a shell-like body 2 providing a gaso ene receivin chamber or reservoir 3. Said shell-like ody is formed with a suitable casing, as (l, adapted vto the mixing chamber; Fig. 5 is a detail vertito contain an inlet-valve, said casing having an inlet end provided with the gasolenepassage 6. ik port or passage? 1n the wal-'l of-said shelllike body 2 connects the interior of said casing 4 with the interior of said reservoir 3. Arranged within said casing 4 is a valve-member, `comprising a ball or otherv suitably shaped valve 8 mounted upon a valve-stem-Qawh-ieh serves, when operated, to open and close the 'gasolene-passage 6 of said valve-casing. rlhe said valve-member '8 is automatically operated by the rise and fall of a float 10, which is arranged within said reservoir `3, said float 10 communicating its movement by means of a suitable leverconnection 11 to said valve-stem 9, in themanner to be clearly understood from an inspection ot lFig. 1 of the drawings. Connected with saidV shell-like body 2, and preferably integrally formed therewith, is a cylindrical body `or member '12, the same providing a suitable mixing chamber 13. rlhe forward end of the said cylindrical body or member 12 is provided with an annular flange 14. l

.The reference-character 15 indicates a face-plate which is provided in its upper half with asemi-circular opening 16,wh1ch forms an airinlet leading to said mixinglsimilar 4gasolene passage 21 chamber 13. Arranged-'between the said flange 14 of said cylindrical body'or member 12 and said face-plate 15 are one or more atomizer-rings 17, the same beingprovided upon their side-faces with circular grooves or channels 18, suitably disposed in the upper portion or half oit' the said atomizer ring or-rings. Extending from said circullar grooves 18 to the inner edges of the said atomizer-ring are a plurality' of radially dis'- posed grooves or ducts 19 which; are of very small cross-sectional area, and thereby tend to thoroughly break up into small particles the gasolene fed from said Ysemi-circular groove 18 when the same flows through said grooves or ducts 19, and. is delivered all around the interior edges of said atomiaer ring 17, so that the said gasolene may be quickly and easily taken-up and intermixed with the air as it rushes through said inlet 16 into the mixing chamber 13. SaidA atomizer-ring 17 is further provided wthfa gasolene passage 20 which registers with extending through the wall of said shell-like body 2, whereby the gasolene eontainedin the reservoir 3 may be delivered to said semi-circular grooves 18, through thesaid passages 20 and 21, and the said transverse passage 22. The said face-plate 15 'and -atomizer ringv 17 are joined or connected; with said annular Flange 14 by means of suitably disposed bolts and nuts 23, passing' through` the ears or lugs 24 which are connected with said respective members. r1he said faceplate'l is further provided with a centrally disposed perforated hub-portion 25 in which is mounted, rotatably', a spindle 26, said spindle beingffrmed with a' shoulder '27.

'l`he outer end of said spindle is formed with a screw-threaded shank 28, upon which is secured, by means of the nut and washer 29, alever'or arm 30 adapted to rotate said spindle. 'lthe 'inner end of said spindle 2G is provided with asquared shank 31 upon which is mounted the hub 32 of a throttlemember 33,. so that said throttle-member will rotate upon the turning of saidspindle 2G. Connected with said squaredshank 31 is a smaller screw-threaded shank 34 adapted to receive thenutfand washer 35 which retains the throttle-member 33 in its operative vconnection v.with said spindle 26'-A Saidthrottle-member 33 isjcylindrical in form and lits snugly Within the opening of said cylindrical body or portion 12, so as toturn therein. Said ythrottle-menfib r 33 is further provided at one end with asemi-circular wall 36, which, when the throttle-member 33 is properly manipulated, tends to close the air-inlet 16- against 'the passage ot air int-o the mixing chamber 13. Said throttlc-member 33 is further provided in co'- incident position and relation to said wallmember 36 with a semi-cylindrical portion 37, which operating Vsimultaneously withv4 sald wall-member 36, upon a proper manipulation of said throttle-member 33, tendsto close against the passage of'gasolene the Said grooves or ducts 19, when the said airinlet 16 is closed.V It will also be apparentthaftinay partial closing of th'e air-inlet 16 byid described, tends to simultaneously close an equal portionof the gasolene feeding grooves or ducts 19 of said atomizer ring 17. Said cylindrical body-portion 12 is further pro-` vided with a boss 38, in turnprovided with a screw-threaded opening `39, and arranged in said screw-threaded opening 39 is an auxiliary air-supply valve, said valve comprising a housing 40 provided with air-ports 41 leading into lan air-passage 42, and a centrally disposeddash-pot 43. Said dash-potthrough the opening 45 in said dash-pet 43,.

said stem being formed-upon its upper end with screw-threads 50.- Arranged upon the screw-threaded portion of said valve-stem is an adjusting nutl for adjusting the tenid throttle-member 33 and its ust.

sionof a coiled spring 52 arranged between the sameand the housing 40. A lock-nut 53 is also arranged upon said screw-threaded valve-stem so as to lock said-adjusting nut 1n its adpisted position. p

Thev operation of the various devices hereinabove described when the said carbureter is carrying out its :function of causing the proper admixture of air and gasolene to provide an explosive gas is as folloajs1-The gasolene from the reservoir 3, being always maintained at a proper level by the opera` tion of said float 10 and said inlet-vz'llve controlled thereby, passes or rises through the passagel andlpassages .20 and into the circular grooves 18 of said atomizer rin g 17. The suction caused by the pistons of tli'e iriternal combustion engine operating in the mixing chamber 18 sucks the gasolene into said grooves 18, and through the small radially disposed grooves or ductslfl, so that thc same is carried into and inteimixe's with the air passing through the inlet 16. /To de crease the .amount ot' gas formed by 'the admixture of gasolene with air, the throttlemember 33-may be operated to close, to the desired degree, the air-inlet 16 and simultaneously shut olf the communication With the mixing` chamber 13 of a proportionate number of the said radially disposed grooves or ducts 1t). In this manner, the strength and quantity `.of the mixture of air and gasolene may be readily controlled by the single operation of said throttle-member 33, as will be` clearly understood. It will thus be seen, that not only is the mechanism I have devised very simple in its construction, but it does in fact eliminate the need or use of a larger number of movable parts which tend to get out of` order; and, furthermore, the i operation of the device is reduced to the greatest degree of simplicity, and the control of the gas, as it is delivered tothe cyl.

inders of the internal combustion engine, is consequently obtained with ease.

Referring now more particularly to the auxiliary air-valve, the operation of the same, briefly, is as follows: At high speed the suction created by thelo'peration of thev pistons in the cylinders of the internal com bustion engine pulls open the valve-disk 48 so as to allow the air to pass through the ports 41 and through the air-passage 42 into the mixing chamber .13. In order to prevent ,the too rapid action of the openingv and closing means of said valve-disk 4S, the.

piston 47 creates a suction in the dash-pot 43, upon the opening of saidoval've-disk 48, which retards the movement of .said valvedisk 48 long eno-ugh to permit thc sucking in of air through the vent 4G into the cylindrical chamber 44 of the dashepot. lVlien the engine slows down hoivever. the spring 52 tends to close the valve-disk 48; but this closing action cannotbe rapid because it is checked by the pressure of the piston 47 in driving or expelling the airfrom said-cylinvdrical chamber 44 through the vent 46 of" scope of the present' invention as set forth in, p

the foregoing specification, and as deined'in the claims which are appended toI the said specification. Hence, I do not limit my invention to the /xac't arrangements andcor.
