ROBERT W. BARTON, OF CHICAGO, ILLINOIS, ASSIGNOR TO BARTON BOILER COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

FLUlD-PRESSURE-CONTHOLLING VALVE.

Specification of Letters Patent.

Patented Aug. 22, 1905.

T0 (DZ/Z whom it may concern:

Be it known that I, Ronnnrr W. BARTON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fluid Pressure Controlling Valves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in throttle or fluid-pressure-controlling valves.

The object of the invention is to provide a valve of this character in which the necessity of providing a stufling-box for the valve-stem is obviated.

A. further object is to provide a fluid-pressure-controlling valve which will be simple in'construction, eilicient in operation, and particularly well adapted for use in connection with automobile-engines.

With these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure I is a central longitudinal vertical sectional view of the valve. Fig. 2 is an end elevation of one end of the same. Fig. 3 is a similar view of the opposite end, and Fig. 4 is a vertical transverse sectional view on the line 4 4 of Fig. 1.

Referring more particularly to the draw ings, 1 denotes the valve-casing, which is preferably formed in two sections 2 and 3. In the section 2 is formed a steam-inlet chamber i and a main steam-inlet port 5, which communicates with the steam-chamber 4 and with which is adapted to be connected a steamsupply pipe from the boiler. In the section 2 is also formed a plurality of steam-outlet ports 6, which communicate with the steamchamber 4. The section 3 is preferably provided on one end with a series of screwthreads, said threaded end being adapted to be screwed into a threaded opening in the section 2, whereby said sections 2 and 3 are connected together. The section 3 is provided with an annular flange or shoulder to engage the ad acent side or end of the section 2, thereby forming a steam-tight connection between the two sections. In the inner end of the section 2 is formeda conical valve-seat 7, with which is connected an integrallyformed bearing-sleeve 9, extending through the section 3 to the opposite end of the same, thereby forming in said section an annular steam-chamber 10. The section 3 is provided with a steam-exhaust port 12, which communicates with the annular steam-chamber 10. A steam-supply pipe (not shown) is adapted to be connected to the port 12, whereby steam from the chamber 10 is conducted to the engine. On the valve-seat? is revolubly mounted a hollow conical valve 13. with which is integrally connected a valve-stem 14, said stem extending through the bearingsleeve 9 and projecting beyond the end of the section 3 of the valvecasing, as shown. To the projecting end of said valve-stem is secured one end of a crank-arm 15, to the opposite end of which is connected a suitable operating-rod. (Not shown.) In the valve 13 are formed steam-ports 16, which when the valve is turned in one direction or the other are adapted to be brought into and out of alinement with similar ports 17, formed in the valve-seat 7, whereby steam from the steam-chambereis ad mitted or cut off from the steam-outlet chamber 10. The pressure of steam in the steamchamber 4 forces the conical valve 13 into steam-tight engagement with the valve-seat 7, thereby preventing the escape of steam from the chamber 4: between said valve and its seat, thus obviating the necessity of providing a stuffing-box or packing-gland for the stem 14 of the valve. The outlet-ports of the steaminlet chamber 4 are adapted to be connected with any auxiliary device required in steam, butnot controlled by the throttle-valve. The casing 1 is provided with a bracket 18, by which the same may be connected with the boiler or other suitable support.

A throttle-valve constructed and arranged as herein shown and described may be quickly and easily operated to admit or cut oil a sup ply of steam to the engine, the construction of the parts being such that the necessity of a stuflingrbox for the stern of the valve is obviated.

From the foregoing description, taken in connection with the accompanying drawings,

the construction and operation of the invention will be readily understood Without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

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

1. A fiuid-pressure-controlling valve comprising a casing, a conical valve-seat formed in said casing, a conical valve revolubly mounted on said seat, a stern formed on said valve to project through said casing, said valve and seat provided with inclined dischargeports, and said valve being held in steamtight engagement with said seat by the pressure of steam in said casing, substantially as described.

2. A fiuid-pressure-controlling valve comprising a casing, a conical valve-seat and a valve-stem sleeve formed in said casing, a conical valve revolubly mounted on said seat, said valve and seat being provided with oppositelyinclined discharge-ports adapted to be brought into and out of alinement to open and close said valve, and means to turn said valve, substantially as described.

3. A fluidpressure-controlling valve, comprising a casing having a steam-inlet port and a plurality of steam-outlet ports, a conical valve-seat formed in said casing, said valveseat having steam-discharge ports, a conical valve revolubly mounted in said valve-seat, said valve having formed therein steam-discharge ports adapted to be brought into alinement with the ports in said valve-seat, a valvestem formed on said valve to project through a bearing-sleeve formed in said casing and a crank-arm fixed on the outer end of said stem to turn said valve, substantially as described.

4. A fluid-pressure-controlling valve, comprising a casing having a steam-inlet chamber and a steam-outlet chamber, said inletchamber being provided with a steam-inlet port and a plurality of steam-outlet ports, said outlet-chamber having a discharge-port, a conical valve-seat formed in said outletchamber to separate the same from said inletchamber, said seat having formed therein steam ports communicating between said inlet and outlet chambers, a bearing-sleeve formed on said valve-seat and extending through said outlet-chambers, aconical valve revolubly mounted on said valve-seat, said valve having ports adapted to be brought into alinement with the ports in said valveseat, a valve-stem formed on said valve, said stem projecting through said sleeve, and a crank-arm fixed on the outer end of said stem whereby the same and said valve are turned, substantially as described.

5. A fluid-pressure-controlling valve, comprising a casing, a valve-seat arranged therein, an annular sleeve connecting said valveseat with one end of said casing, a valve adapted to engage said seat, a valve-stem formed on said valve and projecting through said annular sleeve, and means connected to the projecting end of said valve-stem to oper ate said valve, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
