CARBURETER FOR.HYDROCARBON-ENGINES.

SPECIFICATION forming part of Letters Patent No. 790,379, dated May 23, 1905.

Application filed February 24,1904. Serial No. 195,083.

diana, have invented certain new and useful Improvements in Carburetors for Hydrocarbon-Engines, of which the following is aspecification.

This invention relates to carbureters for 11ydrocarbon-engines such as are used on automobiles and other self-propelled vehicles.

The object of the present invention is the provision of acarbureter which will be of compact form and entirely self-containedthat is, so arranged that the chamber forholding the I gasolene or hydrocarbon fluid and the mixingchamber, wherein the air and gasolene are mixed, will be contained one within the other and all outside communicating pipes, ducts, and other parts will be dispensed with.

Another object of the invention is the provision, in acarbureter, of a novel form of airintake and means for controlling the same.

The invention has for a further object the provision of a novel arrangement of float and valve, the latter on the removable cover to the gasolene-chamber, whereby the float is prevented from tilting and the gasolene is kept at the proper level at all times regardless of tilting of the carbureter when used on an automobile, and provision is-made for rapid removal of the valve, with the cover, for inspection of the interior of the gasolene-chamber.

The invention contemplates provision of other features and novel constructions and combinations of parts, all as set forth fully hereinafter, while the novel features are recited in the appended claims.

In the accompanying drawings, Figure 1 is a sectional elevation of the complete carburcter; Fig. 2, a section on line 2 2 of Fig. 1, and Fig. 3 a section on line 3 3 of Fig. 1.

The gasolene-chamber 1 is in the form of an annulus having the central tubular mixingchambcr 2, provided 'with screw-threads 3, on which the circular cover 4 screws down on the chamber 1. Threaded into the cover 4: is a coupling or union 5, which is connected to the gasolene-tank and has a valve-seat 6 and a Valve-chamber 7, aball-valve 8 being adapted to close the seat 6 when pressed thereagainst by a valve-closer 9, which consists'of an upright stem slidable through a bushing 11 in the lower end of the coupling 5 and provided with a head 12, movable in the chamber 7'and. arranged to engage the ball-valve 8. When the stem is down, the ball-valve 8 is ofl? the seat 6. from cover 4:, is a lever 13, which has a semicircular fork, as more clearly seen in Fig. 2,

Pivoted at 9 to lugs 4, depending which rests upon an annular float 14:, supported on the gasolene 15 in the gasolene-cham ber 1. The valve-closer rests on the lever 13, and when the fluid is at the proper level the float, through the medium of the lever, holds the valve-closer up against the ball-valve and cuts off the supply of gasolene; but when the supply of gasolene becomes too low the ballvalve is unseated and an additional supply of gasolene is discharged into the chamber 1, and the valve is then automatically closed by the float. Tilting of the carbureter orjarring it when used on an automobile is compensated for by the provision of the automatic valve mechanism before described to prevent unnecessary additions of gasolene to the chamber, and. the provision of the fork of lever 13 prevents the float from tilting up on the side opposite where the stem bears on the float, thus insuring reliability of action.

Within the mixing-chamber 2 is the needlevalve casing 15, which is joined to the chamber 1 by the diametrically-disposed conduits or pipes 16 and 17, which take in the gasolene from both sides of-the chamber 1, and thus insure a proper feed to the needle-valve casing 15 at all times, and by positioning these pipeswithin the mixing-chamber I thereby obtain a marked advantage over other carbureters which have the pipes or ducts on the outside of the device, where they are liable to injury, and by the provision of my construction a more compact and a self-contained arrangement is had. The needle-valve 18 has a suitable handwheel 19 and passes through the usual bonnet 20, whereby the supply of gasolene to the mixing-chamber can be regulated. The air-intake consists of the open end 21 of the mixing-chamber 2. Slidable on the needle-valve casing 15 is a throttle seat-valve 22, which is normally held off the air-intake 21 by a spring 23. A lever 24, pivoted to the chamber 1 at 25, cooperates with the throttle-valve to regulate the feed of the air to the interior of themixing-ehamher 2.

It Will be understood that the supply of air and gasolene to the mixing-chamber is regulated to suit the conditions of use by means of the needle-valve,'and the lever and the float and supply-valve automatically take care of the feed of the gasolene to the chamber.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-.

1. In a carbureter, the combination with a fluid chamber and a mixing chamber contained therein, of a needle-valve casing within the mixing-chamber and in communication with the fluid-chamber: a needle-valve for said CHARLES P. lVIlNbS'l.
