CARBURETER.

To all whom it may concern:

Be it known that I, WILLIAM H. BROWN ING, a citizen of the United States, and a resident of Rye, in the county of Westchester and State of New York, have invented a new and Improved Carbureter, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new improvedcarbureter, for use in gasos' lene and like explosive engines, and arranged to permit convenient and accurate adjustment of the needle valve by bodily moving the same instead of turning and screwing the needle valve in or out, and to hold the members of the air admission valve in firm contact with each other by the suction of the engine in drawing in the air.

For the purpose mentioned use is made of a manually-controlled device for movmg the needle valve bodily toward and from its seat to govern the flow of gasolene or other liquid, and an air admission valve is mounted to turn andpressed on by a spring and by the suction action of the engine to hold the air admission valve in contact with its seat.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views Figure 1 is a sectional side elevation of the carbureter on the line 11 of Fig. 2; and Fig. 2 is a plan view of the same.

The carbureter casing A is provided with a top plate B having one or more openings B for the passage of air into the casing A, and the said top plate B is provided with a central upwardly-extending flange B engaged by the hub C of an air admission valve 0 resting on the upper surface of the top plate B and having openings C adaptedto register with the openings B to control the amount of air passing into the cas ing A. The air admission valve 0 is pro- 'vided with a handle D under the control of the operator for turning the valve G to move the openings C in more or less register with the openings B for the purpose specified. Theturning motion of the admission valve G is limited by stops E, E held on the side of the casingA and adapted to be engaged by -the handle D. Thus Specification of Letters Patent.

Application filed November 2, 1910. Serial No. 590,328.

Patented May 14, 1912.

when the handle D is against the stop E, the admission valve is completely open, and when the handle D abuts against the stop E the admission valve is completely closed.

In the flange B screws a tube F provided at its lower end with a valve seat Gr connected with a pipe H extending through the side of the casing A to the outside thereof to connect with a source of gasolene or other liquid supply. The valve seat G is controlled by a needle valve I, having its stem I threaded and extending centrally through the tube F and its cap plate F, as plainly indicated in Fig. 1, and on the stem 1 screws a collar J fitting into the tube F and p essed on by a spring K held in the upper portion of the tube F and abutting with its upper end against the cap plate F while the lower end of the spring engages the top of the collar J to press the latter downward and with it the stem I and the needle valve I.

On the top of the cap plate F is mounted to turn a face cam N having a handle N under the control of the operator, and the face cam N is engaged by an arm 0 guided vertically on a guide pin P attached to the tion of the threaded stem I of the needle valve I, and slidingly engaging the arm 0, face cam N and cap plate F, and on the outerend of the collar Q screws a nut R resting on top of the arm 0 so as to limit the downward movement of the needle valve I. Now when the several parts are in the position as shown in Figs. 1 and 2, the needle valve I is held completely open, and when it is desired to close or partly close the needle valve I then the operator turns the handle N in the direction of the arrow a so that the arm 0 rides downward on the face cam N, whereby the threaded stem I of the needle valve I is allowed to move downward by the action of the spring K pressing on the collar J to move the needle valve I down toward the seat- G. It will be seen that by the arrangement described the stem I and the needle valve I are bodily moved in an axial direction on the operator turning the face cam N so that screwin up of the needle valve stem is not require for adjusting the needle valve relative to its seat, as heretofore practised in carbureters as now generally constructed. By adjusting the nut R on the collar Q the needle valve I may be set nearer to or farther from the valve seat G when assembling the several parts. The collar J is lockedin place on the stem I by a jam nut as 1ndicated in Fig. 1. A spring S is coiled around the tube F and rests with its upper end on the under side of the cap plate F, while the lower end of the said spring S presses on top of the admission valve 0 so as to firmly hold the latter down on the top plate B of the casing A, to compensate for all wear between the conducting surfaces of the valve G and the top plate B. It will also benoticed that when the carbureter is in use, the suction action of the engine 1 n drawing in the air causes the entering air to exert a pressure on the valve C to aid' the spring S in holding the admission valve C in contact with the top plate B.

The bottom of the casing A is provided with an outlet T connected with the engine, and above the said outlet T and directly below the needle valve seat G is arran ed a conical spreader U having a non-perforate point or apex U and a perforate body portion U so that the gasolene or other llquid 'flowing down the seat G drops onto the nonperforate apex U to be spread by the same onto the perforate body portion U to be taken up by the air entering the openings B, C and passing through the perforate portion U to the outlet T. The spreader U is supported by arms V from the bottom of the casing A so that the base of the spreader is a distance above the outlet T, as plainly indicated in Fig. 1.

Fromthe foregoing it will be seen that by the arrangement described, the operator can properly control the admission of the air and that of the gasolene by operating the' handles 1) andN correspondingly.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
