ended in shown -5 28 extends through the sleeve 27, these two arts being threaded as will be understood `rorn Fig. 1. By turning the needle valve 28 it may be raised or lowered relatively to thesleeve 27. The spraying nozzle is shown at 29 and registers with. the lower end of the' needle valve 28. Mounted within the spraying nozzle 29 is a needle valve 30 provided with a revolublev handle 32 and with a i threaded portion `33 which engages .a mating portion 31 of the spraying nozzle 29. By turni-ng the handle 32 the discharge ca acity pvfhe spraying nozzle may be contro ed at The inlet ipefor the gasolene or other hydrocarbon iqnid to be volatilized is shown at 34, and is connected with the valve seat 35, associated with which. is the needlevalve `36. When the carburetor is idle the needle valve 36 rests upon the seat 35, but when 'the carbureteris in action lthe valve 36 is lifted plerodicallyl` so as to allow ingress pf the hyrocarbon '.quid. The needle valve 36 is encircled hy a startling-box 37 which prevents the hydrocarbon liquid from entering the arts of the carbureter in which its presence is not desired. A assage'38is in communi- 40' cation with the in et pi e 34 wheneverv the needle valve 36 is raise( This passage 38 supplies the hydrocarbon liquid to the sprayr ing nozzle 29. A small cani 39 is by means of a'threadedhub 49 and a boss 41 secured rigidlyagainst the top face of the cylindrical l throttle valve 13, as will be vunderstood from Fig. 1. This cam 39 is provided with a spiral slot 42, and itting into the slot is a rollerv 43 mounted upon a stem 44.
provided with guards 45 of arcuate sha e which extend partially around the c lin( er 39 and have a curvature corres on( ingto that of the exterior of said cylinr er. When the cylinder 39 is turned the guards 45 prevent rotation of the sleeve 27, and the roller 43 is thus always held in proper position relatively to theslot 42. The rotation ofthe cyl-- inder 39 therefore simply raises or lowers the.
sleeve 27 and its accompanying needle valve 2S. The large cylindrical valve 13 is pro vided with an opening 46 adapted to register with the opening in the outlet slee-ve 7. This opening 46 has a substantially sl-shaped extension 47, or in other words, merges into a V-shaped mutilation as will he understood the throttle is closed.
The sleeve 27 isl throttle is closed, the valve 13 lmoves still from Fig. 1. The cylindrical valve 13 is further provided with an opening 48 which registers with a somewhat similar opening 49 in the casing 5. Theseopenin'gs are so positioned that they register with each other' 70 when the throttle lever 23 is in the position l indicated in F ig. 2, or in other'words, when When these openings y are out of registry no air can pass `through .'them, and as the throttle lever 23 is adiust- 75 a'ble the openings may be staggered relatively yto eachother so as to admit varying quantities of air. The valve 13 is also provided in its top with an arcuate slot 59 through which passes the sleeve 27. The valve 13 can he so turned to about one-quartenot' arrevolution, this much freedombeing permitted by the length of the slot 50. The cylindrical valve 13 is further provided. with lugs 50" integral therewith andk rejecting internally there- 35 from. Carried y these lugs is a pin 51. Pivotally mounted upon this in is a swinging arm 52 provided with a )aille plate 53 and with an extending portion 54 havin a weight 55. By virtue of the weicht the ha e plate 53 is normally held within, but out of engagement with, the inlet sleeve 6 so as to considerably restrict the inflow of air to the carburetenv When,v however, the swinging arm 52 is tilted and the weight 55 raised, the 95 air space around the baiiie plate 53 is greatly increased. Thatisto say, there is alwa a clear space around the baffle late 53 w ien ever the latter is in itsnorrna position, and this space increases whenever the baile late swings totheleft, according to Figi. pin 56 is mounted rigidly upon the portion 54 of the swinging arm 52 and extends through a square block 57intowhiehit neatly fits. This square block serves as a bearing and fits into a rectangular hearing plate 58'carried upon the outer or free end of a swinging arm 59. This arm is pivoted at 60'and is provided with a rotund portion 69a. Encirclmg this rotund por tion is a bearing sleeve 61 connected with the needle valve 36 andcapable of lifting the laty ter from its seat. n When the baie plate 53 is moved to the'left according to Fig. 1, the pin 56 rises, the arm 59 swings upward upon the pivot 60, and the needlevalve 36is thus lifted. The weight 55 therefore normally maintains the needlevalve 36 upon its seat. lThe `cylindrical valve 13 is 4still further provided with a port f 62 of substanrtiall crescent shape as indi- 1,20 cated in Fi 1. hen the valve 13 is moved into one o its extreme positions, that is to say, when the throttle lever 23 is moved into the position indicated in Fig. 2 so that the further afterthe closure takes place, 'and the oreseentehapfed port d2 registers with a poru tion .of the opening through the sleeve le. This nomini at the same y instant when the openings 48, 4S# ani in registry with nach Ito can the h 'ydrocerbon liquid pass inlet pipe the passage 38 and the spray-f f-iil increase the inflow l on from the center. of the outlet sleeve 7, the.
lili
other. Willen takes piece the air can through. the ports e8, 49, and also throughA theport 52 and le. The enginev thus espirespme cir, which tends to cool it without consuming any fuel. `The suction from the eng-ine, therefor@ produces the'desired effect. The vertical .play of. the Weight 55 and consequently the lateral, swing if the baille plate 525 is regulatedl by adjusting the screw la? hend. A lug 63 is mounted upon. the lever 52, end mounted Within the eylindrial: ,valve i3 and at a slightly higher level. than the; lng 63, is a lng 6d of arcuate torni.. When tinottle is closed, that is, when. the timottle lever 23 occupies the position indiceted in Fig. 2, the lug 64 is directly oni/er the-log; o3 end the bele `plete 58 is un-V able tol swing backward from the sleeve 6.
W hen, however, the throttle is opened to any,
extent the lug 64a nloves'ont ci the way of the lng 63 and. the baffle plate 53 is therefore 'tree to swing.
The operation of roy device is as follows The needle valves 28, and the sore-W 25.
having heen adjusted properly, the engine is started up by. moving the throttle lever 23 from its'position indicated in full lines in taker piece, and the baille plate 53 is caused to swing to the lett according to l in the manner chore de.J armed. The greater the suction exerted by the engine the furtheris tho movementA oi' 'the baffle plete 53 and the higher the lift of the needle valve 36 so as to or" the liquid hydrocarbon. The 'Further the throttle lever 23 .lnovesfroni its position indicated by full lines in Fig. 2 the greater becomes the flow ol air through the e.. :1e le. The V-sheped mutilation 47 into smic-h. the opening t6 merges vallows the "virtuel aree.' to be increased or decreesed very gradually. That is to say, as the cen. ter oi. theA opening gradually moves toward Vehaped mutilation i? of the opening -46 registers .more .or less perfectly with theopenm ing; extending through. the' outlet-.sleeve 7.. f l
When the throttle lever 23-isso' fan turned that-gno' pcrit'olthevmntiletion It?, extends' in to the open space the snctioncf .the cirv .within the ceroureter is 'f totally cutolf.
.the ports 11 and adopted toa'wide range The gradual niovement'of the the throttle lever. .as the arcuate lug 6e is linenfthis occurs-the needieyeltle lefcmoo.-v
.pletely closes the spraying nozzle 29. `By
moving'the throttlelever 23 st ill further, or in other Words, into the position Indicated l by dotted lines. 1n Fig. 3, so to leave the f throttle wide open, the valve 22et last uncovers the port 1l. air through the ports -11 and 16,. and 1n- Thisallows en inflow of creases, disproportionately', the supply of air to the carbureter es the engine attains'its maximum speed. V'Since the additional supply of air thus admitted .at high speeds maynot be suitable for all conditions, the adjustment of the valve 22 relatively to the tubuf lar stein' permits the inflow-oi' air throughl to be adjusted at will as above described.
As willA be eeen from the above description,
the distrihutimioiE air and combustible-vapor .mcy be regulated with great' precision endV the supply oflfiqilid hydrocarbon is totally ont oil in the throttle the supply of air, conl sidered es e factor in explosion, is also cut off. If desired,l after this is done the operator may, by turning the throttle lever'still. fun ther in' the'- direction neceesary forlclosng, admit et will ve. fing quantities of cold for cooling the cailmreter. When the-engine runs etineximinn speedthe supply of air may at will be increased disproportionately tothe supplyof hydrocarboli. Valier. All of thesel results are attained It will also he noted that. beveled. upon its un,n der face the lay ofi the lng' 63 is graduallyv restricted as t 1e ediacent end of thelu-g 64A pasq ses over it. That is to soy, as the rotation of.`
the volvo 13 brings the log 64 over the lug 63 the progressive movement of the lng 64 grad4 ualiy limits more and more the vertical lay of the lug 63. ln doing this, swing'oigthe bathe plete 53 is gradually curtailed. Vice verso., when .the volvo 13`is turned in the op gosite direction the-swing ofthe baffle plate econies of .greater and gre'oter am. .litude until the 'lug 6d is 4entirelyoil' the ng '63. lhese gradu-ii changes of movement in aectfing 59 and consequently atleet the volvo 36. It follows,"thereforgthat the play of the valve 36 and the swingbf the bafflefplnte are proportionatein amplitude. so that the ect-ion of the lug 64 throttle control. H, for any reason', the cam 39,` or- .any of its immediate connections, should be disabled. theyT canbe removed, and
of conditions. -When y by'simply manipulating the baille plate 53 also effect the lever serres to=some extent its a the supply 'of air endiuel` may be controlled through the agency of the lug 64 now 'serving'- as an: a'xiliary throttle.
I tvwill be .noted that.; when lthe throttle .is
vide` open, that is, when the throttle lever 1 23 is in 'its extreme position, indicated vby 'g dotted linesin Fig. 3, theneedle 28 .is 'cleiirr ofthe nozzle- 29, sind so for es the spraying is eonc-erned,v the flow at al mesrnnumel" 'though this maximum is controllable by adjustment of the needle 28. 'It will -also be noted in this connection, that the baille plate 53 swings r'urtlier tothe left according to the View shown in Fig.` 1, When the throttleis wide open, than When partially closed.. It
' follows, therefore, that the baille plate 53 only attains its ,lull svi/ini;` to the left when the spraying' .nozzle 29 is opento its 'inaxif mum extent under a given adjustment of the needle 28. There is, therefore, a definite relation existing between the quantity of air Vadmitted by the swinging of the baille plate- 53,the quantity of fuel capable of issuing' from the spraying nozzle ,29, and the (piantity ol fuel permitted to pass the nozz e 36 which is controllable by tbeballle plate' 53.
`In other Words, there is a double automatic regulation of the flow olthe fuel passing into the carburetor through the s iraying nozzle.
By. this arrangement the main action of the engine is greatly iinproved,I and the control ofthe operator over the speedand steadiness of running isv increased. v
vThe' construction above described promotes regularity in the lowol the hydrocarbon liquid. ln many carbureteis it happens that' variations in the hydrostatic prestill i sure ofthe carbon liquii 30: into the" carburetor at greater velocity at one monnent than. ati-another.
over, that when mypofnstruction is used, the
due to dillerenccs in the level thereof, ieause. the liquid to flow I` lind, how# vfor the purpose 'of bringing air into .contact A with said hydrocarbon liquid so as to lorii'ira'ri explosive;mixture, a :movable battle plate for partially obstructing the llow of air through,L said air inlet, a lever supporting said baille late, a cylindrical member. encircling said ever, and a' lu yot arcuate' form mounted u on saidoyliiii rical member and provided with a bevel face for controlling fpiiifntita-v tively the degree ol" movement of said level'.
