To all whom it may concern:

Be it known that I, Jomv S. Gotonsao,

a citizen of the United States, residing atmatic adjustment which enable regulation of the gas' How with a minimum number of operations, there being only one lever whose operation serves to control the mixture and feeding of gas to the engine.

In the` accompanying drawings which illustrate my invention, Figure 1 shows a top view of the carburetor, various parts having been removed in order to show the valve seat and the` seat for the float; Fig. 2 is a sectional view taken on line 2-2 of Fig. 1, the'parts removed in Fig. 1 being shown in osition; Fig/8 is a sectional view taken on ine 3-3 of Fig. 1; Fig. 4 is a sectional view taken on line 4-4 of Fig. 1, and Fig. 5 is a top view, showing the valve in position on the valve seat.

The frame 1 supports at one end the spindle valve seat 2 and at the other end the cylindrical frame 3. Extending upwardly from the valve seat 2 is the hollow cylindrcal standard 4 through which extends the valverod 5, having. at its lower end a re- 40 duced extension 6 terminating in the valve point 7 for controlling the inlet 8. Thron h the walls of the standard 4 just above t 1e hase 2 'are the diametrically opposite openings 9 and 10 in which are pivoted on pi"- ots 11 and 12 the levers 13 and 14. The inner ends or points 15 and 160i these levers respectively engage the shoulder 17 of the valve rod while the outer arms 17' and 18 of the levers engage the float cylinder 19 which float is hollow and which has a central'opening 20 through which passes the standard 4. Extending upwardly from the frame 1 and surrounding thcvalve seat part 2 is the angular projection 21 within which 55 is disposed the lower end of cylinder 2,2

which is preferably of glass or other transl parent material. A cap 23 ts the upper end of t-he cylinder 22 and has a central threaded opening 24 for engaging the threads 25 at the upper end of the standard 4 A guide nut 2G is also adapted to engage the threads at the end of the standard and has the guide 27 through which passes the upper end 28 of the valve rod. lVashers or gaskets 29 and 30 being placed in position, asshown, and the cap 23 and lock nut 26'screwed into place, a sealed chamber is provided. By means of suitable fittings 31,-

the valve chamber 32 may be connected through pipe 33 with a source of oil supply, such as gasolene. When the lient reservoir is empty, the Weight of the float will he suficient to turn the levers 13 and 14 to raise their inner ends and consequently to raise the valve rod to hold the spindle valve pin 7 up to 'oplen the inlet 8 tc allow entrance of,A

oil Into t e reservoir. However, as the oil rises in the reservoir, the weight of the float will be lgradually lifted :from the levers, z ,i when t e oil reaches a certain fined the weight of the valve rod will. over w.. the weight of the float and will drop to close the inlet 8. With this arrangement the oil in the reservoir is automatically maintained at a constant fixed level. By means of a cock 34 suitably connected with the fittings 31, the reservoir may at any time be drained.

Within the cylindricalframe 3 is the cylindrical valve seat frame 35. The interior 36 of this valve frame is connected with the air inlet 37, while the channel or outlet 38 through the body of the valve seat frame connects through passageway 39 with the reservoir, as best shown in Figs. l, 2 and 3, the passageway 39 leading through the supporting frame L The space surrounding the valve scat frame constitutes a carbureting chamber 40 which may be connected through outlet 41 with the engine in an;v suitable manner. The valve block 42 is mounted on top of the valve seat, as shown in Figs. 2, 3 and 5, and a guide stem 43 extends downwardly r'om this valve into the guide pedestal 44. Extending upwardly in the chamber 36 through said valve block is the horizontal passageway 45 for receiving crank pin 46, extending from the crank cylindcr 47, journaled in the bearing frame 48 extending laterally from the frame 3, as

Y crank pin 46 will cause vertical rcciprocaVv Y tion of the valve block. In vthe top of the ,valve block is a cylindrical pocket 50 for' receiving a worin Wheel 51 whose support ing 'stem 52 at one end is journaled in the pocket 53 and Whose upper end extends through an opening or 'gnidevvay 54 through cap 55 and nut extension 56, this cap' having a threaded flange 57 for engaging the threaded upper end 'of the frame 3, the nut part 56 being integral with the cap part. The Worm Wheel is confined in the pocket 50 by the plate 58 held to the valve block by the screw 59, the valve stem 52 passing through the opening 60 in this plate. Extending through the valve block and through the edgeofthe pocket 50 is the Channel 6l which registers with the outiet 38 which communicates through the channel 39 with the reservoir. Alf'lxtending through this channel 61 and into outlet 38.

is a valve rod 62. At the upper end-of this valve rod is a groove 63 Whose rear face has the teeth 64 engaged by the Worm Wheel so that rotation of the Worm Wheel 'will cause vertical movement of the valve rod. Thelower end 65 of the valve rod is out away at a gradual bevel, as best shown in Fig. 3, and'thus as the valve rod is raised or lowered, the area of the end of the outlet 38 is increased or decreased correspondingly. The vertical movement of the valve rod is limited by the upper and lovver Walls of the groove 63.

The level of the oil in the outlet passage way 38 Wili be the same as that in the reserH voir, and when the engine is to be started, the arm or lever [i9 is turned a suitable distance, thereby raising the valve block to open communication through `the chamber 86 and between the inist 37 and the carburetii g hamber 4G and aise te raise the valve rod 62 to establish.ecmmunication between the outlet channel 38 and the carbureting chamber. When the engine is started, the

suction draws in air through `the pipe 37- `which air rushes through between the valve block and top of the valve seat past the end of: the outlet 38, thus sucking up the gasolene from the passageway 3S which gasolene is thoroughly vaporized and mixed with the air in thecarbureting chainberbefore passing to the engine. The desired proportion between air and gasolene is as adjusted by turning the stem 52 which may be done by means of a wrench engaging the polygonal end 66 of the shaft 52 supporting the Worm wheel, and this proportion of gasoiene and air will be maintained during any adjusting movement of the arm do. This proportion of adjustment could, ot course', be accomplished in the first place by giving the Losoaes proper taper to the end ttfnoii the valve rod 62, but this would require. enact and expensive workmanship and besides might very easily lose, its adjustment,v By the useof the worin Wheel adjusting arrangemenhjust the ordinary care need be taken in lieveling theend 65, the lino adjustment. being accom- -plishcd by the i'vorm W iecl arrangement.

lnstead ot employing set screivs t'ohvold the crank shaft et? in its bearings, lcause the flange 57 to perform this function, this `flange extending inlo an annular groove 67 surrounding the inner end of the crank shaft 4T. v

lt will be not-iced that the construction and arrangement of my device are very simple, ,iti requiring very little Work to get at any of the parts, both for Iinspection or repairs. For example, if the spindle valve in the reservoir is ydesired to be inspect-ed, itis .necessary only to unscreW the capnut drawn. :lf itis desired to examine the doat, thecap nut 26 and cap 30 are removed whereupon the float can be lifted from the standard s; also by removing thecap 55 from ,the frame 3, the crank mechanism may. be immediately` withdrawn and'V the valve block with all its attachments lifted from the seat, and this simplearrangement is: a very desirablefeature. The" reservoir cylin der 22 being of glass enablesready determination of the levelof oil or the position of the float in the reservoir. be limited, however, Vto the exact arrangement and construction shown and described, as changes maybe readily made. without departing from the scope of my invention.
