WILLIAM s. xELLeee, an, or rEoaIA, ILLINOIS.

To all whom it may concern Be it known that I, WILLIAM S. KnLLoee, Jr., a citizen of the United States, res1ding at Peoria, in the county of Peoria and have invented certain new and useful Improvements in Carbureters, of which the following is a specification.

My invention relates to carbureters. The object of my invention is to provide a carburetor operating wholly under the influence of a current induced by the en gine to apply a uniform quality of mixture without regard to the speed at which the engine is run.

Another object of my invention is to provide means for controlling the mixture of air and the liquid base to produce the desired mixture.

My invention consists in the provision of a combined float and carbureting chamber, means for raising the liquid base to the induced current through the carbureting chamber, means for controlling the liquid exposure to the air current and for mixing the same, and other details of construction hereinafter more particularly described.

Referring to the drawings-Figure l is a side elevation showing the general form of the device; Fig. 2 1s a Vertical sectional view on the line 22 of Fig. 1; Fig. 3 is a side elevation with parts broken away to show interior construction; Fig. 4 is a top view on the line H of Fig. 1; Fig. 5 shows one form of a templet, and Fig. (3 shows another form of a tempiet.

Referring to the figures, A refers generally to a combined float and carbureting chamber formed of two sections 2 and 3 adapted to be joined together in any suitable manner to render-the joint therebetween perfectly air and gas tight. The liquid fuel base is designed tobe, carried in the lower portion of section 2 and the flow. of liquid into said section is controlled by float 4c in the usual well known manner.

5 is an air inlet into the carbureting portionof the carbureter and 6 is a mixture the engine, the" air inlet and mixture outlet being preferably arranged in different horizontal planes.

7 is a disk adapted to be arranged within the combined float and carbureting chamber in substantially the relation shown.

7 are perforations through the body of the disk which I have showp .as angularly Specification of Letters Patent.

disposed with relation to the air inlet and mixture outlet or both.

8 is a spindle to which disk 7 is fixed and which is provided at its ends with cone points 9, the respective ends adapted to be supported in cone bearings in set screws 10 and 11, the latter being carried in suitable threaded openings in the body of the chamber in substantially the relation shown.

The mixture outlet is controlled by but terfly valve 12 which is supported 011 suitable spindles journaled in the walls at the mouth of the opening out of the carbureting chamber, the movement of said valve being adapted to be controlled by the op- 13 fixed upon 18 refers generally to a. templet portion of a brake arm connected through cast part arm 19, said teniplet being preferably formed as shown in either Figs. 2, 5 or 6 according to the associated use with different engines, in which figures the face 20 is formed straight and the face 21 cam shaped. The cast portion 22 of the com plete brake arm is adapted to be fixed in an adjustable relation in connection with crank arm 19 within slot substantially as shown in Fig. l. The lower portion of arm 18 is adapted to depend through slot 24 in cast extension 17 and the face 20 of said arm has normally a bearing relation with push rod 15. The initial position of arm 18 with relation to push rod 15 is adapted to bc fixed by means of set screw 25 substantially 'l helyform of the cam Variation, can be determinedonly by test, and is accomplished by first with relation to the screw 25 and push rod 15 to proper working condition on low speed. Then the valve is openmlstep by step with the increase of speed. Then by av series of tests to determine the adjustment at points intermediate the extremities of the templet, the required variation of distance.

setting the arm llO between the faces 20 and 21 of said templet will be also determined. Commonly, if not uniformly, the most abrupt braking effect will occur at the beginning of the opening of the butterfly valve and thereafter the increased braking etl'ect required will be ordinarily very gradual up to the point of the complete opening of said valve.

The form of the float chamber and carbureting chamber, and in structure that forms said chamber may be varied to suit the requirements of use except that they shall be in communicating relation. The air inlet and mixture outlet openings likewise may be modified to accommodate varying conditions of use. The brake mechanism adapted to control the speed of disk? may be in any suitable form to accomplish the purpose, for instance, the construction may be such that push rod 15 may have a direct bearing upon the face of disk 7.

I have shown in the drawings a brake mechanism adapted to control the speed of wheel 7. However, under certain conditions of use this brake mechanism may be dispensed with entirely. For instance, a carbureter may be associated with engines of a certain uniform and defined structure. In such case the combined area of the perforations in disk 7 and that of the air inlet may be so proportioned that the disk wheel will be automatically cont-rolledand its speed confined within limits consistent with the working c-.nnbination in which it is used, to produce a uniform quality of mixture throughout the variations of speed at which the engine is run. The brake mechanism is provided merely to render a single tiillbllreter adaptable for use in connection with any engine. 1

in operation. the parts having been adjusted in the. relative positions shown in the drawings, the initial starting of the engine having been accomplished and the butterfly valve 1; opened. as thepistons of the engine are. rcciln'm'utcd. a current of-air is induced through air inlet 5, perforations '4' of the disk wheel 7 and through mixture outlet (3, and from thence into the engine cylinder. The action of the. air being drawn through openings 7 will cause disk 7 to be rotated, serving to raise. the liquid base into contact with the air passing through the carbureting chamber and as it is thinly spread upon the surl'acc of thcdisk' and upon the walls of the. perforations. it is readily taken up by the air. and as almost ercry particle of air passing through the chamber is brought into contact with liquid in condition for ready vaporization, a perfectly natural mixing occurs that renders the mixture perfect withoutauxiliarv mixing means. at least in the ordimirilv low or moderate speeds of the speed of the engine 1nengine. ;'\s the.

fact the combined,

creases the speed of rotation of disk 7 will be proportionately increased, serving to equalize'the exposure of liquid to the air current in proportion to the increased flow of air through tne carbureting chamber, thus insuring a proportionate mixture. of the two basic elements of the mixture that will effect a constant uniformity of mixture. The flow of mixture into the engine is always under control of the operator through and by proper manipulation of the butterfly valve, as is well understood.

As previously of perforations 7 in disk 7 is properly pro portioned to the size of the air inlet, no con trol mechanism is needed to limit the speed of said disk. However, as also previously stated, in order to meet the varying conditions of use of a carbureter with any engine, a control may be found necessary.

The operation of the control mechanism is as follows: The proper. adjustment of brake arm 18 having been made with relation to push rod 15, the opening of the butterfly valve to admit an increased flow of air with an accompanying increase in the speed of the engine would result in an increased speed of disk 7. Because of the disk having a free support upon its bearingfthis would result normally in a proportionately greater speed of said disk than that of the increased flow of 1 air therethrough. To check this normal tendency to greater proportionate speed, the brake mechanism is connected up with-butterfly valve 12 so that as it s opened the brake arm 18 is depressed,

and being in bearing relation with push rod 15 pushesthe la ttcr into frictional brake contact with auxiliary disk ll. The form of the brake arm is such that with the increased opening of the lmttertlyw valve there will be,

exerted a greater brake force applied to auxiliary disk force being adapted to be such as to confine the speed of disk '7 within a certain defined limit so as to prevent too great an agitation of the liquid within the carbureting chanr ber.

It may be that other mechanical means mi ght be employed to raise the mixture base to-thecourrent passing through the carburet ing chamber and to agitate the same within certainpractical limits, and it may be that the relative positions .of the air inlet and mixture outlet may be such toperforations in the disk thatsubstantially straight peril, such proportionatebrake" stated, if the combined area f forat-ious at right angles with the faces of the disk may be employed and still induce the desired rotation therein, therefore 1 do not 'vish to confine myself to the particular detail structure which I have herein shown and described, but it is my desire that it shall. comprehend a'ny'and all forms of err bodim'eutpf my invention that fall legiti ii'iately withinthe principle th'ereoi.
