, BACH, a citizen of lat Rochester. in the county of Monroe and 'State of New York, have invented certain Carbu- Be itl known that 1, Hnxnr M. REICHEN- the Unitedv States, residing new and useful improvements in retcrs; and I do hereby declare the follovving to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to carbureters for internal combustion engines and proposes a construction of carbureter whereinv the suction of the motor is utilized i to effect a more intimate and finely divided admixture of fuel' and air than is noiv obtained, therebyT enabling the use of fuels having higher boiling points than those usually employed. The invention has for its further object to produce a carbureter havingmeans adapting the same to be used in connection With a dynamometer or similar instrument for determining its `different Working conditions to the end that the carbureter may, from the observations made at different speeds, be calibrated so as to make it possible to automatically7 bring about the best Working condition of the vcarbureter in the future operation of the engine.

y lVith these and invention consists in the arrangement and combination of parts hereinafter claimed, and While the invention is not restricted to the exact details shovvn and described. still for the purpose of disclosure reference is had to the accompanying drawings, in which plete apparatus.

device; and

ig. 14 is a sectional View of the same taken on the line 14-14 of Fig. 13.

Referring to the construction in detail the appara-tus consists in a casing comprising tivo semi-cylindrical sections 1 and 2 and a shell 3. Fig. 3. The sections 1 and 2 are secured together at'one end by al bolt 4 and at the other end by a band or ring 5, and at which end said sections tit within a collar 6 formed integral with the shell 3. The shell 13 is constructed 'with an inner annular Wall 7 of substantially the same diameter as that of the sections 1 and 2, and with which it communicates and forms a continuous channel for the air taken through the opening 8.

The means for feeding fuel to commingle with the air consists in a tank 9 secured to the casing by brackets 10, Fig. 2. A float 11 is mounted Within said casing to have movement on the stem 12 of a needlelvalve 13, and which valve it is designed to automatically actuate. The valve is normally held seated through the medium of a cap 14 which fits over the upper end of the stem 12 and is held seated thereon through the medium of a spring 15, Whose tension may be regulated by a cap 16 that is screw-threaded on the cylinder'l? Within which said spring is seated.. A pair of levers 18, which are 'journaled- 1'. e. when the tank 9 is filled with iiuid said levers 18 engage only lightly against 'the collar 21 and allow the valve 13 to be held in `j usted laterally of its seat 22 through the tension of the spring 15 and thereby effectively close communication with the fuel supply pipe 23. If, on the other hand, the level of liquid within the tank 9 drops below normal the weight of the float 11 on the levers 18 causes the levers ends 20 to lift the collar 21 and thus open the valve against the tension of said spring 15, and thereby allow the fluid. to enter through the pipe 23 until the required level is obtained 111 the tank 9 lwhen the parts ag'ain assume their normal position, as shown in Fig. 2. I

The fuel is -fed from the tank 9 preferably through a super-heater or vaporiz'er and fuel eduction valve the apparatus for which consist-s ina pipe. 24 having a passageway 25 which communicates with afluid controlpipe 26, as shown in Fig. 2. The pipe 26 'is axially and slidabl movable within a sleeve 27. The sleeve 27 is secured to rotate in the head 27a by the glands 28a and 29a that, are"screw-threaded in said head. Said pipe 26 has an aperture 28 that registers with an'aperture 29 in the sleeve. The apertures 28 and 29 are in register with the passageway 25 of the pipe 24, and to regulate'the amountof fuel commensurate with the speed or load on the motor, said pipe 26 is constructed with a lug 30 which fits within the aperture 29 and is designed to be adforcetfecting said adjustment consists in a knurled 'head 31 that is screw-threaded on i the threads 32.on the outer end of said pipe 426, and which is secured to a split ring 33 by screws 34. The ring 33 is mountedcto 'rof tate in an, annular groove provided by the collars 35 and 36 formed integrally with the sleeve 27. The knurled head is gratinated as shown in Fig. 5 which may be read with respect to an indicatingpoint on the collar 35.A Vith this micrometer gage it will be obvious that turning the. knurledhead 31 will-effect endwise movement of the pipe 26 and thereby cause the lug 30 to vary the extent ofl cross-sectional opening of the passageway 25 communicating with ythe opening 29 in the sleeve 27. The opening of the pipe 26 communicates for its full diameter with the external atmosphere, thel purpose-'whereof being first to admit air which mingles with the fuel admitted into said pipe from the reservoingas will be un- `derstood from the construction in Fig. 2, and secondly to prevent motor acting' on'the jet, so that the feed of fuel into the tube 32 and the superheater is partially by gravity. It may be stated that this latter is one of the most important features of the present invention. It is proposed to provide a. means for regulating the to this end is designed, as instance the pipe amount of air so admitted, and ka modified construct-ion shown 1n Fig. 13. In this said aperture. The means4 bracket 54 that issecured to the vrvsuction lof, the f extent of the openings 37 proportionately tol',

the extent of the opening 29.

As above stated, it is proposed to provide automatically actuated means for varying the amount of fuelvfed into the carbureter, and to this end it is designed to have means actuated-by'Y the fuel eduction valve 39. Said means consist (see Figs. 1,4 and 5) of levers 40 and 41 secured by clamps 42 and 43 to the valve shaft 44 and sleeve 27 respectively. The shaft of the valve 39 is mounted torotate in the casing (1 and 2) and since the extent of such rotation is' dependent directly upon the suction of 'the engine, .it will be evident that the connecting levers 40 and 41 will rot-ate the sleeve 27 a corresponding distance and vary the extent of the opening 29 communicating with the passageway 25.

The means connecting the levers 40 and 41 (see Fig. 12) consists in a bolt 45a and a milled headed nut' 46 screw-threaded thereon. The bolt 45a end with a slotted head 45 adapted 'to be se'- cured to a graduated sector 47 that is carried by the lever 40, and which indicates the position of the valve on the arcuate scale 49. The sector plate 47 also serves for setf ting and xing the levers 40 and 41, and consequently the, eduction` and'fuel supply valves, at' different relative positions.

The lever 40 is lprovided onv 42 thereof with anannular groove 50, within whichis secured at one end a cord 51 that connects at its other end with a spring 52 (Figs. 1 and 2). to an adjusting screw 53 mounted on, a

the casing section 2. Said bracket has a slot adapted to to receive a projecting piece 55 of a nut 56, which is threaded on the screw 53, the pui-, pose whereof being to' secure the adjusted position of said screw. l

An arrangement for determining the tension on the springA 52 is shown in Fig. 10.

In this construction either end of said is provided at one the portion p in Fig. 9, wherein thecord '51 passes over a., pulley 60 and carries ber of weightsl at the lower end thereof. The fuel and air distributing or eduction valve consists (see Fig. 6) of a casting 39 having a cover plate 39 and constructed the necessary numwith inner' and outer walls SZa'nd 63 1'@ 1KB-.

" s'pectively"providing passageway 64,i which communicates with an openingG in'the journal lsgew'aly 64 is ldesigned apertures '66 and through the therewith a pin 72 y axially with'the bearings 44 and 70 thereof` a channel or mixture 44. The pasl to conduct the fuel to a plurality of apertures 66 formed m the vend oftheiwallj, and through which apertures 'the mixture is divided vcondition into the passageway through the carbureter casing 1 and 2. The

*wall`562 has secured therein a plurality of jets or nozzles 67 that register with the ,are designed to deliver jets of air thereto 69 of the Cvalve journal 70.

The' `fuel .eduction valve has associated a wing 71 pivotally mounted on that is journaled in the *valve co- (see Fig.` The wing 71 with the fuel educ-tion valve is designed to effectively close communication through the carbureter casing, and said casing has the walls thereof suitably constructed to permit of actuation of said valve andvwing, which movement of the valve is effected directly suction of the engine. A stud or bolt 73 is screw-threadedin the casing section 1 and provides a stop or support for the fuel eduction valve when in closed posit-ion. Said wing is designed to be movedv independently of the fuel valve in thedirection counter to the flow of air admitted through the opening 8,' the purpose whereof' being to guard against the damage of the fuel valve incidentl to probable vin a removable plate back-firing. Two springs 71a connect the wing 71 with the fuel valve by the eye pieces 74 and 75 on said wing and valve respectively and 'normally hold said wing and valve in proper relative position.4 Under certain conditions, as for instance in the possible event of excessive back firing,

'it may be desirable to provide an additional safety valve. This contingency is provided for=b 1 the valve 76 mounted to open outward y of the casing. A spring 77 mounted -on the valve stem 78 seats against a washer 7 9 on said stem and keeps the valve 76 normally closed.

An alternative construction of the fuel eduction valve is disclosed in Fig. 7, where- 80 is attached to the valve casing 81. and with a heat insulating Alayer 82 secured b v a plate 851- provides the necessary chamber for the commingled air and fuel and air passageways. In this construction the wing 84 is fixed to the valve as distinct from having movement independently thereof.

A super-heater orvaporizer is located intermediate the fuel eduction and fuel regul'ating valves -a nd comprises a. casing 85 secured by al brachet 85a to the section 1, and having a partition 86. Said casing is delivered in finely n from the chamber. 68, which receives the air through the ope-ning mounted on the pipe 265and pipe section 87 to permit of sliding movement ofthe pipe 26 and rotary movement of the pipe section 87. The passageways through said pipe 26 and pipe section 87 communicate with the chamber in the casing 85 to either side of the partition 86, and a bent pipe or U- shaped tubeV 88 brings said chambers into communication. A casingv 89 incloses the tube lengths 88 and is removably secured to the casing 85 and provides therewith a. chamber 90 adapted to receive a heating medium,l viz :p-eXhaust gases, steam, or hot water, from a delivery pipe 91. pipe 92 located adjacent the lower end of the casing 89 provides an outlet for the heating medium. By having the inclosing casing 89V vremovably secured, said casing may be readily disconnected for the purpose of cleaning.

It is proposed to provide a super-heater with an automatic feed control, and to this end the arrangement shown in Fig. 8 is suited. The construction thereof comprises a valve 93 having an arm 94, which iseonnected by a link 95 with an arm 96.l The arm 96 is in turn secured to the lever 40,

which'carries the graduated sector piece 47, which sector is in this instance formedL integral with the arm 40. By this construction it will be apparent that any movementof the fuel eduction valve will edect a proportionate movement of the valve 93 controlling theadmission of the heating medium to the super-heater.

A butterfly throttling valve 97 is iournaled within the casing section 1 immediately below the fuel eduction valve and is designed to regulate' lthe flow of air which enters through the opening 8 of the lower section 3. Said throttle valve is designed to be manually actuated, .to which end a crank 98 is secured to the valve shaft 99. On its opposite end the shaft 99 carries an arm 100 secured to rotate with said shaft by a clamp 101. The arm 100 carries on its outer end a Screw-threaded bolt` that is provided with a milled nut 103, which secures the head of the bolt 10'2 in engagement with a graduated section 106. that is secured to the casing 1 (see Figs. 1. 4 and 5). The purpose of this arrangement is merely to enable the reading inldegrees and secure the position of the va ve.

AIn order that the fuel eduction valve and an' regulating valve may be closed through the same manual source, the construction shown in Fig. 11 is proposed. In this ar.- rangement the valve shaft 99 has the lever 100* thereof connected bya link 107 tman arm 10S secured to the shaft 70 of the fuel eduction valve. The connection between the link 107 and arm 10S consists in a stm1 109. that is designed to slide within the slotted portion 110 of said link.

A similar The disposal oflv so y l nected.'b v a pipe/115. with stationary and the stud 109 and said 'slot is such that when the arm 107 is moved upwardly it wlll engage with the stud 109 and move the arm 108, while the downward movement of the arm 107 will allow the stud 109 to remain thereby not move' the arm 108. Also by reason of this slot and stud connection between'the arms 100a and 108 the air throttling valve 97 may be adjusted independently of theadjustment o'f the fuel distributing valve. Y A fan 111 of an anemometer is mounted within the air inlet S ing 11Q`and 113 is adapted to connect with and actuate the counter (not shown) for determining the velocity of air admitted through said air passageway.

Avacuum gage lll for the engine is conthe casing (1 and '2) at a point above thefuel eduetion valve as valve 11G closes shown in Fig. 2. ,A relief, an opening 117 at the bottom of the lower casing 3 and is held in closed position by a spring 1l8`mounte`d on'the valve stem 119.

and which seats against a cross piece 120v formed integral with the casing' 3 and with a washer 121 on said stem. Said relief valve is. in addition to the wing 7l and valvet, also designed to act in the back-firing of the engine. v

It is obvious that those skilled in the art may-vary the details-of construction and arrangement of parts without departing from the spirit of my invention.- and therefore I do not wish to be limited to such features except as may berequired bythe claims.
