Specification of Letters Patent.

Application tiled November 30, 1910. Serial No. 594,830.

To all. whom it may concern:

Be it known that I, CHARLES P. SIMMONS, a. citizen of the United States, residing in New York city, county of No York, and State of New York, have invented new-and useful Improvements in Carburcters for Int ernal-Combustion Engines, of which the following is a specification.

This invention relates to improvements in carbureters for internal combustion explosive engines, and has for its objects the provision of means for regulating the supply of gasolene in a' more etiicientland exact manner than has heretofore been accomplished, and at the same timeto admit of the suitable admixture of said gasolene with the air within the carbu'reting chamber prior to the admission of the same into the This invention particularly consistsof the the patent to E. M. J. iVeinat and Joseph Bogey, No. 867,859, of October 8, 1907, and also patent to E. F. and G. H. Abernethy, No. 895,709, of August 11, 1908, and itwill be noted that while the invention described in this application embodies, among other ele ments, a reservoir somewhat similar to the one described in the former atent, and a rotating elementsomewhat similar to the plug 8 described in the latter patent, that nevertheless there are certain radical and valuable improvements over and above either of the constructions shown in the aforesaid patents.

The invention is fully set forth in detail in the accompanying specification and drawings forming a part thereof, in which,

Figure 1 'is a central vertical section of my improved carburetor; Fig. 2 is a fragfrom within the container B, looking at right angles to the axis of said container; Fig. 3 is a horizontal sectional view, and Fig. 4 is a vertical sectional view of the construct-ion shown in Fig. 2; Fig. 5 is a sideelevation of one-half of my improved carbu'reter, and Fig. 6 'IS a. central vertical section of the same (the carburetor being modified) along the line zv--:v of Fig. 5; Fig. 7 is a vertical section at right angles to that-of Fig. '6, and Fig. 8 is a detailed section on the line. y-y of Fig. 7 Fig. 9 is a fragmentary vertical-seetion showing a. modified form of container having an integral journal, and Fig. 10 is a fragmentary sectional detail of the conto by a hinge 11,.being sition with respect to the part 9 by means of r.be1ng readily taint-r wall shown in Fig. 6; and Fi 11 is a central vertical section of a modifier form of carburetor.

Referring to the drawings, the reference numeral 2 designates th casing of a cylindrical carbureting cham in which aciroular valve 3 is mounted -nd adapted to be oscillated upon gudgeons 4 and 5, the latter being provided with a pinion 6 which is arranged to mesh with the annular gear 7, and that is in turn swiveled upon a shoulder 2 of the casing 2. 'The said annular gear is operated by means .of the arm 8 which is pivoted to a connecting rod 8 and thus in operative connection with the throttle-com trolling 'rneehanism of the well known type. Below the chamber 2 is positioned a twopart approximately spherical casing A, the upper half '9 of which is integral with the casing 2, and the lower half 10 constituting a semi-spherical screen,'is connected thereheld in a closed the screw-cap l2. Arranged within this casing, orhousing, is a fluid fuel receptacle or container B which is provided with a gudgeon 13 and a bearing 14, and thereby being pivotally mounted as indicated and removable from the casing when the lower part is thrown into the position indicated by the dot -and-dash line in Fi 7. Portions of this container are also de ormed with respect to. a' sphere, one side being of greater curvature than the to o said contamer and the other side 16 be ing prefer-a ly flattened as shown, (see Fig. l A series of fine orifices 17, 17 is arranged periphcrally in a single horizontal line, all at the same level, from a point adjacent the gudgeon 13 to a point adjacent the bearing 14.. These apertures as shown, are

preferably 'interiorly enlarged in order to lene contained within said container will be permitted to pass through said orifices, while at the owin to its fluidity, tends to How very rapidly through even the smallest of apertitres, will be somewhat retarded in its flow the'rethrough. A sheet metal casing; is arranged along the inner wallof said spherical container adjacent the "casing consists of a vertical front .wall 18- i and a bottom-plate 18 l a portion of the said frontwall 18 being said orifices. Said integral therewith,

same time the gasolene, which.

40 spond with and to receive the partitions 19, and thereby the said partitions are more cut away adjacent the center in order to expose the central orifice 17. As shown the said bottom-plate is secured to the casing immediately below the level of the orifices. The casing is partitioned as indicated by the reference numeral 19, intermediate certain of said orifices, in such a manner that with the exception of the central orifice'll,

- which as stated is exposed, several ofsaid orifices will communicate with a single one ofthe compartments a, a a and pernnt of the escape ogt gasolene therefrom.

' The vertical walls of the successivecompartments each extend to different levels on either side of the central orifice 17, sothat gasolene will be successively admitted to thecompartments a 0. on either side of said central compartment a according to, the degree to which said container is tilted and thereby a re'gulated and 'predetermined amount of gasolene is permitted toescape from the orifices. For example, upon the .slight tilting of said container thegasolene will escape from the orifice 17 leadingfrom the central compartment (1, but upon increasin the tilt of said container the gasolene wi 1 flow from the'orifices leading from.

the compartments a, a, and upon the further tilting of said container, in a like man-' ner the asolene will escape in addition from .the ori ce. leading fromthe compartments a, etc. These compartments being preferably very narrow, being but approximately 1 g of an inch in. width, admir ably serve for the reception of small StIIPSOI pieces of chamois 20, which serve as a packing to restrict the excessive fldw 'of the gasolene through even relativel small orifices. Preferably the inner sur ace ofthe container is scored or grooved to correconveniently soldered orotherwisesecured to the said wall, and the leakage of gasolene from one compartment to another is prevented. r 5

The annular ring 24 not only serves as a support for the air screen 10, but also con-- stitutes a seat into which the container B closely fits when in a closed position, thus admission of the'inlet of air to the carbureting chamber is entirely cut off.

The eccentric'curvature of one side of the a container serves when it is oscillated on its hearings to afford a carefully graduated air inlet opening between the container and its seat; i. e. the inner'face of the ring 94, and the said current flowing fpast the openings 17, or as hereinafter set orth the openings 22, while theo'pposite flattened portion 16 serves, when the container is oscillated in the op osite direction, to admit of the passe of air on the o posite side of said contamer and distant mm the aforesaid openinge. However owing to the spher cal conesaaov adapted to be operated by means 0 a bellcrank lever 26and connecting rod 27 which is operatable from the dash-board of the car.

A; valve 28 controls theinlet ofgasolene' to the container throu h the ipe 29 from the gasolene tank. A va ve casing 30 is threaded into the boss 31 of the wall of the casing A and maybe set in any adjusted position desired andthen secured by a set-nut 32. The valve stem. 33 extends downward and into the float-stem chamber 34 which is held rigidly in position by a valve casing 30, the

end of which projects throughv the opening in its wall-as shown in Fig.

Arranged within the container is the float 36 and stem 37, which is secured to a fulcrum pin 38. The outer end 39 of thest'em is preferably flattened in orderto afford a support for the reception of the beveled end 40 of the valve stem 33. Upon the top of the container (see Fig. 1) is arranged a segmental gear 41, which meshes with the gear 42 on the oscillating valve 3, whereby when the shaft-leis turned to open or close the said valve '3, the container is correspondingly oscillated in its bearin s. On each side of the gear 41 is arranged a flange 43 the top of which is flush with and slightly above the top of the gear teeth.

gem-s41 and 42 are correspondingly of varying width as shown, the purpose of which is that when the valve 3 is in a closed position,

the container can be put in place, and the teeth of its gear 41 will engage with those of the gear 42, only when the container is in its proper position with respect thereto, and in proper adjustment with the upper valve' or in other words, whenthe 'valve 3 is closed the container will assume a closed position with reference toits seat in the ring 24.

' In Fig. 9 is shown a modified construction of a bearin and sup ort, for a container B, and in t e same -t e shaft'4t, integral with said container, serves as a bearing therefor. A float stem 37, being fulcrumed at 46, engages a stem 47 of a valve 48, the

latter being normally adapted to close pressure from the 'gasolene confined al/ove the same. When employing this construction, an inner sleeve 49 is provided (see Fig. 9). The said shaft 45 is provided with a elotted'opening 50 for the reception 'of the lower 'end of the valve casing 30', whereby the rotation of the shaft 45 1s peragainst the ",The faces of the.

mitted and the sleeve 49 is held in stationary position during the said rotation of the shaft 45.

In the modifiedconstruction, (see Fig.

l'l), A is rotated in its seat by means of a .pair of links 53Iand 54, which are connected sion at air into'the-eng'ne. 66

to ears 55 and 56 on an annular ring 57 which latter is seated in a recessedportion a of the top of the container, the other ends of the links being connected to the opposite side of the throttle .valve 3, and the valve in this construction is operated by means of the lever 58 externally mounted with respect to the housing shown, and provided with a segmental gear 59 which engages the pinion (30 upon the axis (31 of the valve The operation of this mechanism is evident from the construction as the container is adapted to oscillation in thesame manner as in the other construction previously described.

The operation of. the device shown in Figs. 1, 2, .3 and 4 is substantially as follows:-- Upon the operation of the throttle lever so as to effect the opening of the valve- 3, in the direction of the arrow, the gear 41 engages with the gear 42, etl'ecting'the rotation of the container in the same direction as the other arrow, and consequently, the orifices 17, being all at the same level, will be' moved downwardly, and gasolene will be admit-ted into the compartments submerged therein, and obviously the more said openings are depressed the greater will be the number of the compartments submerged in the gasolene. Simultaneously, air is admitted between the curved outer surface of, the container and the inner surface of the ring :24, the current being obviously induced by.

the suction stroke of the engine -pisbon. The said current of air serves to supplement the actionof' gravity, when aspiratmg the gasolene through the orifices 17, andserves moreover to effect a complete atomization of said gasolene with the consequent thoroughmixture'ot the same'within the carbureter chamber. When the car is running down hill, since no power is therefore required, it, is desirable that the gasolene supply be shut off and air be admitted in order to cool'the engine. This can be conveniently accomplished by throwing the throttle lever in the opposite direction, whereby the valve 3 is opened to a corresponding extent, and 'the container isrotated so as to furnish quick andfull inlet of pure air, while preventing the-escape of gasolene through the orifices 17, said orifices being obviously elevated to a point above the level of the gasolene within the container. The air passes between the inner faceof the' ring 24 and the closed surface of the the aforesaid position to etfect' -the admis- -Inthe construction shown in Fig, 6 and part 16- of said ,con-.. tainer when the throttle lever-is thrust in the corresponding figures, the container wall is shown provided, through a considerable area, with a. plurality of orifices 22, and it slight movement of the container so as to depress the lower. row of orifices 22 below the gasolene level, the gasolene will be impelled through. said orifices due to gravity and aspiration of the inflqwing' air current, and as the number of orifices which are brought below the level of the gasolene increasesthe reater will be the flow of gasolene from t e said container. Preferably, in order to restrict the flow of gasolene through the orifices 'in the manner previousl described, these orifices are also packe with small chamoisplu s 44'. The configuration of the container s iown therein is extremely important since it not. only admits of greatly enlarging the capacity ofthe: container without increasing materially the total size of the carbureter, for as well known a. sphere has a greater cubic content that any other geometrical figure, but also since the cross sectional area at the point of the greatest dimension of the container is substantially 'co-extensive with the. interior cross sectional area of'the housing,

the said container itself for'ms avalve. Thereby any protruding valve-elements which are likely to become deranged or worn most etiicient and simple manner. Another important featurein addition to the enlarged capacity, and the fact that the com tainer also constitutes a valve element of the mechanism, is the fact that the container is adapted to-be rapidly and instantly removed either for putting the engine out of commission and preventing so-called joy riding or for heating the container when chilled to elevate the same to the proper temperature to insure the necessary volatilization of the gasolene, and the consequent immediate start-ing of the engine irrespective of the external temperature. As a matter of fact, although it isoften advisable in cold weather to place the said containerupon a steam radiator a few minutes, the starting of the engine will be remarkab}y facilitated if the container is merely carried in ones pocket to'inipart thereto the relatively slight warmth obtainable from the body.

Having thus described-my invention, what I claim and desire to secure by Letters Patentis'a- .1.' In a carbureter, the' comliination-com- 'being extendln through the Walls of said container, a apted to permit' the escape of gasolene from said container and into said housing.
