Toallwhom it may concern:

Be -it lmown that I, GEoncE J. ZlscH, a subject of Germany, and a resident of Newark, in thevcounty of Essex and State of New, Jersey, have invented certain new and useful Improvements in Carbureters, of which the following is a specification.

The/invention relates to improvements in carbureters for hydrocarbon engines, and it consists in the novel features, arrangement and combinations of parts hereinafter described, and particularly pointed out in the claims. n n

The object of my invention is to provide a simple and highly elicient carbureter for automatically supplying gas of the requisite quantity and qpality to the cylinder of an engine, 1n accordance with the work to be' performed. I contemplate the use of my carbureter in connection with the cylinders of automobile engines for supplying gas thereto.

The lcarbureter of my invention' comprises, preferably, a cylindrical casing affording a mixing chamber for the air and gas to be connected by suitable piping with the en gine cylinder, and a receptacle for the gasoing-chamber and to be connected with a suitable tank or source of supply for the j gasolene.

The receptacle -containing the gasolene will be provided with afloat for closing,

in accordance with requirements, and saidtube or pipe leading from said valve mechanism into said mixing-chamber and preferably Aformin the pivotal axis 'of a suitable valve ofvthe utterly type for controlling the passage through said chamber. said tube or pipe is formed, within the'mxing-chamber, with an outlet opening for n gasolene and preferably containsa wick or body of absorbent substance which becomes saturated with the gasolene and while permitting a proper discharge thereof into the mixing chamber prevents any undue quanto said chamber above the butte through the carbureter.

asolene from the tank or The i.

tity 'of theA gasolene from entering said chamber; The mixing chamber is provided Patented lie. 5, 1911.

at its lower portion with a suitable air inlet and anv automatic check-valve therefor. The butterfly valve controlling the passage through the mixing chamber and the valve mechanism controlling 'the variable passage of gasolene to the discharge tube or pipe connected with said valve and adapted to discharge into said chamber are .connected together and operate synchronously tov admit proper proportions of air andgasolene y' valve in accordancel with the work required, whereby as the buttery or air valve is turned to increase the opening through the mixing chamber, the said valve mechanism will likewise open to a greater extent tofsupthe increased quantity of'air then passing My invention results in proper combus tion, high eiciency in the engine and great economy in the consumption of the gasolene, as well as accomplishing other important advantages.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to' 'the accompanying drawings, in which: Y

Figure 1 is a central 4.vertical section through a carburetery embodying my inven- 'ply the requisite quantity of gasolene to tion, the section being on the dotted lines 1--1 of Figs. 2 and 4; Fig. '2-isa like secf tion of the same taken at a right angle to the section of Fig. 1 and on the dotted lines 2-.-2 of Figs. 1 and 4; Fig. 3 is a horizontal section ofthe same on the dotted line 3-3 of Fig. 2; Fig.- 4is a top view ofthe same,

the pipe leadingv from the carbureter to the engine cylinder being shown in horizontal section;Fig. 5 is an enlarged detached vertical section, on the dotted line `5 -5 of Fig. 2, of the gasolene valve mechanism for securing a variable admission of 'the gasolene tothe transverse discharge pipe or tube in the mixin chamber; Fig. 6 is a like section through t e same on the dotted line 6-6 of Fig. 2, Fig. 7 is an enlarged 4detached view of the wick or absorbent body which I prefer to employ inthe transverse gaso-v lene discharge pipe or tube, and Fig. 8 is a sectional view correspondin but showing a modification o thegasolene valve mechanism in that the valve-disk (3l) with Fig.` 5v l tures ('32) shown in Fig. 5.

In the drawings, 15 designates the exterior` cylindrical shell or casing of the carbureter, 16 a top plate thereon, 17 a bottom plate applied thereto, 18 a vertical tubular section concentric with and within the said exterior casing and forming within it the mixing chamber and conduit for the air and gas, and 19 a semi-circular float within the gasolene-receptacle 20 formed between the exterior casing 15 and tubular section 18, said float preferably being-in two members connected together by a plate 14 hinged to a bracket 13 and having a laterally projecting lip or lever-arm l2, as shown more clearly in Figs. 2 and 3.

The receptacle 20 may be supplied with gasolene or the like from a suitable tank, not shown, connected with a nipple 22 screwed into the top-plate 16 and having a port, 23 leading to said receptacle. At .the upper portion of the rt 23 is a valve-seat, as shown in Fig. 2, a apted to the valve 24, whose stem 25 extends downwardly through the port 23 in position to be acted on by the lever-arm 12 of the float 19 to open said port when the float descends by the lowering of the level of asolene in the receptacle 20 so that an additional supply of gasolene may enter said receptacle. When the level of the asolene in the receptacle 20 lowers, Vthe oat 19 will turn downwardly and cause the lip or lever-arm 12 to move upwardly against the valve stem 25 and elevate the valve 24 rom'its seat to admit an additional quantity of gasolene to the receptacle 20, and then as the gasolene reaches its predetermined level in the receptacle the float riding upwardly will turn the lip or lever-arm 12 downwardly from the valvestem 25 and permit the valve 24 to lower and close `the port 23, thereby cutting o the supply of asolene to said receptacle.

The out et for gasole'ne from the receptacle 2O to the mixin lchamber 18 is through a valve-mechanismthe transverse pipe or tube 26 which is pivotally mounted and extends transversely across the mixing chamber and is provided with an outlet orifice 27 in said chamber, said valve-mechanism comprising a stationary disk 28 having an arcuate recess 29 open at theouterface of the disk and in commnnication with a ort 30 opening freely. through the edge 0F the disk into said receptacle, -anrintermediate disk 31 rigid on the adjacent end of the pipe or tube 26 and having a series of ports 32 of preferably gradually increasing diameter arranged on the arc of a circle and to be brought one after another into register with the arcuate recess 29, and an outer cap 33 fitted upon and secured to a laterally projecting periph- Figs. 2, 5 and 6) and eral iiange on the disk 3l and forming bel tween itself and said disk 31 a chamber 34 which is closed at its outer side by said cap and into which chamber the end of the pipe or tube 26 o ens to receive its supply of gasolene there rom. The chamber 34 receives its gasolene through the port l30 and recess 29 of the disk 28 and through such of the series of ports 32 of the rotary disk 31 as may at the time be in register with the said recess 29, the flow of gasolene to said chamber and thence into the discharge pipe or tube 26 bein variable in quantity according to the positlon of the ports 32 of the disk 31 with relation to the recess 29 of the disk 28.

The disk 28 has a hub portion set into the side wall of the mixing chamber 18 and it is stationary and affords a bearing for one end of the rotary pipe or tube 26. The disk 31 is fast on the end of the pipe or tube 26 and is in .face to face engagement with the disk 28, being held firmly in such engagement by means of a nut 35 on the open end of the pipe or tube 26 and a spring 3.6 on said pipe or tube and acting expansively between a side wall of the mixing chamber 18 and a collar 37 on the outer solid portion of the said pipe or tube. The spring 36 and collar 37 are within a chamber 38 partitioned off from the receptacle 2 0, and said collar carries a stop-arm 39 provided to limit the rotary movement of the pipe or tube 26, said arm at its lower end contacting with the wall of the chamber y38 when the said -pipe or tube has turned to the extent intended to be permitted and arresting the same.

The tube or pipe 26 carries, within the mixing chamber 18, aA disk or butterfly valve 40 which is utilized to more or less open or close the passage through said chamber, said valve, tube and the gasolene feed-control disk 31 always moving in unison and hence proportioning the respective quantities of gasolene and air that shall vcome together in the mixing chamber above said valve 40. The tube or pipe 26 and parts connected with it receive their motion under the manual control of the operator or driver through any suitable mechanism comprising, for illustration, a connecting rod or link 41 pivoted to a cranklarm 42 rigid on a solid projecting end 43 of the tube 26, said end 43 and tube 26 being mounted to have a rocking or angular movement to such extent as may be required for admitting the proper quantities of air and gasoleneto the mixing chamber 18 and securing the proper mixture for the engine cylinder in accordance with the work to be performed.. The tube 26 will preferablycontain a wick 50 or similar absorbent body adapted to hold a body ot the gasolene and aid in controlling the discharge from said tube into the mixing chamber.

The upper or cap-plate 16 contains a cen- "iti chamber and said plate may be fastened by screws 44 to the usual engine cylinder. y

The bottoni-plate or capv 17 has air-inlets 46 of small size leadin to an interior airpipe 45 leading to the chamber 47 formed in t e lower part of the` casing 15, and also a 'large air-inletv or opening 47 leading to said chamberbut normally kept closed by a check-valve 48 held on its seat by 'a light spring 49. During t-he use of the 'carbureter the valve 48 will be automatically opened to a greater or less extent as may be required by the suction created by the piston of the engine on its suctionstrokes. In the chamber 47 is provided a disk 51 of wire-cloth to screen the air which may pass to the mixing chamber. v

The top and bottom plates 16, 17 may be removably clamped against the ends of the casing 15 by means of vrods52 whose upper ends are in the form `of adjustable bifurcated members straddling lugs 53 on the top-plate and carrying eccentrics 54 to be operated by handles 55 for'engaging, with binding force, the upper concaved surfaces. of said lugs.

The lower ends of the rods 52 are confined in lugs 56 on the bottom plate 17 and are provided with heads 57' to prevent their upward movement through said lugs. By releasing the eccentrics 54 the casing 15 and all its parts below the topplate 16 may be removed from the vehicle,V

and this is a feature of advantage for several reasons. l

The operation of the carbureter will be understood from the foregoing description withoutgfurther extendeddetailed description.

The carbureter having been applied to position and the receptacle 20 having been supplied with gasolene, the operation of the airvalve 40 and gasolene disk-valve 31 for the admixture of the gasolene and air will be under the direct control of the driver on the.

car through the medium of the connecting rod 41, crank-arm 42 and tube 26. The suc' tion stroke of the piston of the engine will be depended on, in the form of my invention illustrated, for opening the air-valve `48. The driver will open the valves 40, 31

to a4 greater or less extent as the requirelments of the enginemay demand. f It is one of the important features of the invention that by means of the valve 31 the driver may regulate the quantity of gasolene that shall escape to the mixing chamber and that at the same time he may control, by the posit-ionfof thevalve 40, the quantity cf air in said chamber to mix with the gasolene. The operation`- of the valve 40 in controlling the passage of air through the mixing chamber is obvious. The disk-valve 31 contains the series of apertures 32 which in effect constitute an elongated narrow port and as said disk is turned to carry more or less of the port into communication with the gasof thence escape into the mixing chamber 18- will vary accordingly. If only a light load is imposed on the engine onlyfa small quantity of gasolene will be required; under a heavier load a larger quantity of the gasolene will be required, and under a maximum load a still larger quantity of the gasolene will be required, and all these variable quantities of gasolene, with the proper proportionatequantities of air, may be secured by the simultaneous movement of the diskvalve 31 and air valve 40. When the diskvalve 31 is moved to carry say two of its apertures 32 into register with the recess 29 .a certain quantity of gasolene may pass te' the pipe 26, and as more of said apertures are carriedinto register withsaid recess a larger volume of gasolene is permitted to pass to the pipe 26. As the pipe -26 is turned By means of my invention the driver may very readily regulate the escape of the gasolene into the mixing chamber and the passage of the `mixture ofgasolene and 'air through the carbureter to the engine.

The series of apertures 32 in the disk 3l will preferably be of gradually increasing diameter, as shown inv Fig. 5, although I do not regard this as a limiting feature of my invention. Il desire it to be'understood that I do not limit my invention to the vforms and. details of construction hereinbefore specifically described, since these may vary considerably within the plan and spirit of my invention and with individual preference or judgment. I illustrate the elongated port through the valve-'disk 3] as composed of a series of apertures 32 but I do not confine my invention to the separate apertures since if the partitions between the apertures were cut away, thus leaving a narrow slot, as

.air-valve40is transversely across the mix- `mg chamber, as shown, only-one of the apertures 32 in the disk 31 will be in communi.- cation with the recess 29.
