Fig. 6 is a detail View of the sleeve with which the slide cooperates. Fig. 7 is a. sectional View of the fuel feeding nozzle and concomitant parts, showing the saine on a larger scale.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings, by the saine reference characters.

rl`he loodyfoi2 the carbureter is indicated at l and may be of any construction and is usually hollow to admit of ture passing therethrough. tion shown., the body .l is

ln the construcof tubular lorrn and apnroximately of lv-shane and is adapt-v ed to be connected to the intake'or supply pipe leading,` to the engine in any manner. One member of the U-shaped body is of larger diameter than the other member and is adapted to receive the covering mechanism and the means for controlling the air and fuel inlets. The receiving; end or" the body is closed as indicated at 2 and is formed with an enlargement having a passage 3 for the supply of fuel, said passage being; adapted to be connected with the feed pipe leading to the tank or reservoir containing the gasolene, or other gas-producing agent. A Valve e threaded into an extension of the end 2 controls the passage The valxeseat is fori-neil at the delivery end ofthe pasanil is adapted to be closed lay-means of a valve G, which latter may be vol" any form and carried by a rod or stein?. nozzle 8 malice a screw thread connection with an extension projecting from the inner side of the end 2 and this nozzle has a flared opening; 9 which receives the valve and the upper ond of the rod or stem 7. The opening' 9 'is contracted at its lower end and channels or' ,grooves 10 walls thereof to provide passages for the fuel when the carburetor is in operation.

A, )luralitv of o )cnino's ll. are formed iny the gaseous inizi-- are formed in the' of regulating the size of the openings 11 to admit more or less air according to the nature of the gaseous mixture to be supplied to the engine'. An air regulator' 14 is att-ached to the rod or stem 7 so as to move therewith and is approximately of cup-form. said regulator fitting within the body 1 and having openings 15 in its side walls corresponding in number and position with the air inlet openings 11. Movement of the regulator 14 varies the size of thel inletI openings 11 as will be readily understood. The horizontal or bottom portion of the regulator 14 has openings for the passage of the air and fuel. The centralportion of the bottom of the regulator 14 is closed and of conical form as indicated at 16. so as to direct thd fuel outwardly to vard the opening in the outer portion of the'bottom of the regulator to meet with the incoming air so as to provide a mixture which is subsequently agitated by means of a rotary fan to break up any particles of fuel to insure the formation of a homogeneous gaseous mixture to attain the best possible results from combustion. The apex of the conical generator`16 of the air regulator comes opposite the discharge of'the nozzle S. The air regulator 14 is moved automatically with the rod or stem 7 by a governor mechanism presently to be described. A jacket 17 surrounds the upper portions of the body land is adapted to have warm air supplied thereto from any Source, whereby the conversion of the fuel into gas is greatly facilitated.

The rod or stem 7 is mounted vin a tubular portion 18 at the bottom of the body 1 and in a support 19 secured within the body at a point between the upper and lower parts thereof. The support. 1t) may be of any construction so long as it admits of'a gaseous mixture passing freely thereby and at the same time provides 'a substantial sustaining means for the upper part of the rod or stem 7. The central portion of the support 19 has a eene Q0 which is centrally apertured and internally threaded.l A shortbearing sleeve 31 has its upper end threaded to the cone 20 of the support i9 and receives the rod or stem 7 which is mounted therein to move vertically, said sleeve having an annular enlargement which forms upper and lower cones. A hub 2:3 mounted upon the bearing sleeve. 521 and has fan blades 3 connected thereto. 'The upper end of the hub 22 curved inwardly to form a cup which overhangs the upper cone, balls 24 being interposed between the upper cone and' the said cup. Amit. 25 is threaded to the lower 'end of the huh 2Q and has an inner extension end lapping the lower cone of the bearing sleeve so as to support balls 2G which are interlmsed between the said lower conc and the inner extension of the nut 25. The upper and lower ball bearings between the hub of the fan and the bearing sleeve 21 admit of the fan rotating freely with a minimum amount of friction from vert-ical or lateral stress. The nut- Qhas oppositely .disposed arms 27 which incline outwardly and downwardly. Governor arms 28 are pivotally connected to the lower ends of the arms 27 and each of the governor arms is of elbow-form, the pendent member being weighted at its lower end and the `upper member b .ing forked to embrace the arm 27 and having the fork members connect-ed by means of a pin 29 upon which a' roller 30 is mounted. ,A cone 81 is. pinned or otherwise secured to the rod or stem 7 so as to move therewith. A cup 32 is mounted upon the cone S1 and balls are interposed between the cone 31 and eu p to admit of the latter rotating freely. A nut 33 is threaded into the lower end of the cup 32 and holds it to the cone 31. The rollers 30 are in contact with the cup 3Q and when the weighted ends of the governor arms 2 8 dy outward, the horizontal members of the governor arms are depressed at their inner ends and move the cup 32 downwardlyand the rod or stem 7 therewith with the result that the valve 6 is moved away from the seat 5 to a greater or less extent and the air regulator 14 lowered thereby uncovering the openings 11 to admit a greater amount of air to mix with the `increased quantity of fuel being supplied. A spring 34 of helical form and of the expansible type is mounted upon the rod 7 and exerts an upward pressure upon he cone 31 to hold the valve 6 seated and the air regulator 14 elevated. The upper end of the spring 34 is adapted to engage the lower end of the cone lower end engagesthe upper end of a sleeve 35 mounted upon the rod 7 and secured thereto and arranged within the tubular extension 18 of the body 1.v A set' screw 36 threaded into an opening of the sleevey 35 serves to secure it to the rod 7 in anadjusted position. Vert-ical movement of the sleeve 35 varies the tension of the spring 34 whereby greater or less resistance may be ot'l'ered to the movement of the governor mechanism whereby provision is had' for regulating the action of the governor mechanism according to existing conditions to attain the best possible results. The sleeve 85 may be adjusted vertically by any means and yshown a slide 37 1s used and is adapted to be connected with a lever of any Itype not shown) under control of the operator when the carbureter is installed. The slide 37 is forked,

-and the forked members embrace opposite sides ofthe lower portion of the .rod 7 and pass through openings formed in the tubular extension 18 and engage out awayportions and 39 in opposite sides of the` sleeve 35. The inner edges of the forlre members of the slide 37 incline to correspond 81 whereas its i 3o end l2 admits of' meines 5 ing it to oilier egreater resistance to the rotation oi the fen 23 thereby reterding the :iet-ion or" the governor mechanism. Gut- Werd `.inovernentof the slide 37 causes depression of the sleeve 35 with the result that '10 the tension of the spring is lessened,

thereby decreasing the resistance offered by seid spring to the rotation of tlie fen 23 with the result that the action of the gow ernor mechanism is facilitated to admitot e.

greater amount of sir and ges being supplied to the engine. l

ln the practical operation ot'a carbureter embodying the invention, it is obvious that the rod or stein .7 may be moved by e govergo nor mechanism of any-type so long es the same is actuated by the gaseous mixture drawn through the cerloureterby tlie engine 'when in operetion. lt is to lie understood that the carburetor is adopted to be connected to the engine in any suitable wey.

The fuel passage 3 may loeregnleted by the .valve 4 and the sir inlets ll are adapted to be controlled by the band l2 in the manner started. Proper adjustment of the parte e s gaseous mixture oi -proper consistency seing'.'obteined When engine is in operation eir drewn 'intlirongli 'tlie inlets ll. and 'fuel through the' passage 3, yseid fuel conrzning'ling,r vvitn 3.3 sir end forming e gaseous mixture which,

pessingtlirongli the ren 28, censos the to rotzite. The velocity of tlie ten 25 will depend upon the rapidity with Wliicii the' gaseous mixture is drawn 'through the cerlo bureter, hence, as the speed ofthe engine increases, the gaseous mixture. will ne drown through the cnrbureter rapidly thereby increasing the degree ol2 rotation of the ten end since the governor mechanism depends e5 upon the rapidity of rotation of tne fen,

tlie 'valve t and the nir regulator le will oe nio-ved e distance corresponding' to the degree of rotation of the governor' srins. Should it, 'from any cause, be desired to rd the action of tlieisn consequentlv t'ne governor mechanism, the slide 37 nigey lie pressed forward, thereby increes ing the tension of the spring lei. @n the other hand, should it oe desired to facilitate the operation of the governor nieclionisin,

the slide 37 is drown out-Werd, thereby decreasing the tension ot the spring 34- and diminishing,l its reterding action in e manner hereinloeore stated. A slight movement ont the steam 7 suilices to 'fully unseat the vulve (i, utter which n continued movement ot the stein 7 serves to cut oli' the supply of liquid 'fuel by reason of the valve 6 moving downwardly in the tapered opening 9. 'llie slide 3'! muy serve es means for tl'irottiing eppended hereto.

t-lie engine, 1out it preferred e` seperate valve .may be provided either to oct jointly with the slide 37 or independently tliereoa es tlirottling ineens. The speed oi tlie engine niey be increased by increasing the tension or the spring 34, whereby greater iorce is required to nieve the valve 5 downwardly in the opening 9 zitter being moved away from` its sent- -5 to the fullest extent. 'By Varying the tension of the spring 3,4 the friction be tween the moving parte is likewise yeried and the gres-ter the friction the greater the force required to rotate the fan', hence 'it follows that the speed of 'the ten ineyv be controlled by varying the tension of tlie spring'- 34@ and in turn controls the governor lmechanism which automatically regulates the supply of the air and uel to the engine.

lt will be understood troni the foregoing teken in connection with tile accompanying drawings tliet tlie invention supplies e carburetor for use in connection with internal combustion engines which, when set is entol'netic in operation to supply en increased ernennt of fuel es the speed ot the engine A increases or to diminish the supply of geseous mixture to the engine es the speed of seid engine slncliens. The isn in addition to forming actuating; menne for the governor mechanism also ves to agitato tlie mixture to insure :i thorough incorporation oi the oir and thereby producing e. homogeneous mixture Wliicli insures the leest possible results in the operation oit the engine.
