NEW YORK, N. Y. PANY, OIE JEILSEY eAnnUnE'rEa.

' of New York, respectively, have` invented new and useful lImprovements in Qarbureters, of which the following is aspecication.

The invention relates to improvements in devices forfcarbureting and mixing air withV hydrocarbon liquid fuels such as are utilized in the hydrocarbon engines.

The invention particularly relates .to the ,means which regulate the amount of airv passing through the carbureter and the amount of fuel which is supplied to said air; It furthermore relates to a carbureterin which the air traveling through the carbun invention reference is' made'to the drawings the same.

in which,

Figure 1 shows a side view ofthe completed carbureter. VFig. 2 is a plan. view'bf Vvalve occupy when the carbureter is not being used. Fig. 5 is a transverse sectional View taken on the line 5 5 of Fig. 3 looking in the direction of the arrows. Figs.-6 and 7 are detail plan views of the bypass valve. Fig. 8 is a vertical section at right angles to the section shown in Fig. 3. Fig.- 8 shows the-manner in which the' valve seats.

The completed carbureter comprises three distinct parts, namely, the float chamber A, the atomizing chamber B and the mixing chamber C. e

The float chamber A is provided with the supply duct 1y having at the extremity Specification of Letters Patent.v l

thereof the drain cock`2.' There is an opening leading from the duct 1 to the interiorv of the Aiioat chamberwhich is controlled by the valve 3 to which is connected the vertical spindle 4. A float spindle 5' is slidable upon and relativeto the-valve spindle 4 and this float when the liquid inthe chamber is below a certain amount Arests upon the collar 6 secured to the spindle 4 to depress the valve and permit fuel to enter the chamber. There is `secured to the upper end of the spindle 4 an inverted cup 7 surrounded f by the cup shaped sleeve member 8 4vertically adjustable in the screw socket 9. Betweenthe cup members7 and 8 there is a spring. whose tension can be regulated by the turning of the sleeve member 8 normally held from rotation in its socket by the spring pressed pin 10. l

The atomizing chamber B is provided at its lower end with the triangular air inlet opening 11 controlledv by the spring pressed curved valve 12 which is of uniform width from end to end.` The fuel comes to the atomizing chamber from the float chamber through the

Aducts

13, 14 and 15 and the area of the discharge' opening is .controlled by a needle valve 16 the position of which 'i can be regulated by turning the screw threaded member 17 normally held from rol tation bythe spring pressed pin 18. At

`l9 is provided with a longitudinally extending aperture 21 through which the air passing through the` carbureter normally travels and into this aperture portion the I discharge end of the fuel supply terminates. A

Tt will therefore be apparent that the suction of the air upon the fuel supply when the valve is seated will correspond to the amount of air drawn or passing through the p carbureter. Now when the air required' for any certain position of the air inlet valve exceeds a certain amount the suction will increase suiiiciently to cause a lifting of the 'valve 19 from the seat and when this point has been reached it will be apparent that the suction of the air upon the fuel will not correspondinglyv increase 4the amount of fuel delivered thereto. in other words some of the air is ley-passed from 'the inlet end oli the carburetor directly into the delivery side of the atomizing chamber without it all having to pass through thedraperture into which the fuel supply discharges.

In order that the valve 19 may be properly maintained in place in the atomizing I detachably secured in place by the'bolts 23a.'

The spring pressed air inlet controllmg valve 12 previously reierred to .is carried on a shaft 25 having connected thereto the op.-

erating arm 26. This shaft also carries an arm 27 which has pivoted thereupon at its free end the curved cam 28. There is also carried by the arm 27 a swiveled member 29 having a. threaded member 30 passing therethrough and held from longitudinal. movement therein. A. nut 31 with which the screw threaded member 30 engages is pivotally secured to the cam 28 in a manner to effect the changing of, the radial position of a portion of the cam relative to the axis of the shaft 25. The carburetor alsol has a rocker member 82 comprising a shaft 32a' parallel with the shaft 25; an arm 33 secured to one end of shaft 32a, having a roller 34 at the free end thereof in engagement with the cam 28 and a forked arm secured at the other end of said shaft, which .straddles a nut member 36 on the needle valve 16. It will thus be apparent that by swinging the lever v26 from the closed/position of the carburetor shown in Fig. 4, to the position shown in Fig. l, that the air valve 12 will be moved from the dotted position shown in Fig. 3 to the full line position and 'that the needle valve will be drawn from closed position to open position due to the fact that the radius of curvature of the cani 28 increases going away from the supporting arm 27.

The means which operatively connect the air inlet valve and the fuel supply needle valve comprise a movable member namely the cam 28, the iree swinging end of which can be adjusted to different radial positions relative tothe axis of the shaft 25A andthe construction of the operating parts in this connecting mechanism is such that in one position of the movable member a xed ratio between the openings oi' the iiuel and air supply may be maintained and in another position of the movable member other vary-` ing ratios may be maintained between the air and fuel supply openings. ln fact this. movable member can in one position main-` tain a constant ratio between the areas 1oit' the openings during the movement of the airinlet `valve from closed to open position in another position of the movable member the ratio of the iuel area to the air area may be variably increased with the opening of the air valve while in another position of the movable member the ratio of the fuel opening to carburetor than if the air valve were not so` located. Y l l claim as my invention:

"l. ln f a oarbureting device having an atomizing eliamber and a mixing chamber the combination of a spring pressed valve in the atomizing Ichamber, a bar detachably secured to the walls of the earbureting device, a valve spring between the valve and bar, and a mixing member carriedby the bar.

2. In a carbureter a bar supporting at one side thereof downwardly extending air valve uidingmembers, a hollow air valve member. slidable thereupon, fuel delivering means terminatimgr Within the opening of the valve and a rotatable mixing device having its axis of rotation in alinement with the axis of the opening in the hollow valve member.

3. .d oarbureter having an upright casing with a main air controlled valve at `the lower portion thereof, a fuel supply leading to the interior of said casingf and terminating above the main valve opening, a hollow air valve within which said fuel supply terminates, a transversely extending; bar detachably secured in the upper part of said casing, depending members secured thereto for guiding said hollow air valve, an upright stud carried by said bar and located between said depending guiding members, and a mixingy member mounted on said stud in the path of the gaseous mixture which passes upwardly past said bar.
