FLUID-PRESSURE REGULATOR.
SPECIFICATION forming part of NLetters PatentNo. 522,683, dated July `10, 1894. Application filed May 12, 1894:. Serial NoflLOZl'. (Nomodol.) v
To al? whom it may concern.: i 1
Be 1t known that I, GEORGE H. WALKER, a
citizen of the United States, residing at Gincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Fluid-Pressure Regulators; and I do hereby declare the following to be a full, clear, and exact description of the mvention, reference being had to the annexed drawings, which form part of this speciy l fication.
This invention relates to those devices which employ a flexible disk or diaphragm for con'- trolling the movements of an inletvalve,'so as to maintain a constant pre-determined pressure of Iluid or gas in the apparatus to which the regulator is connected, and myim'- provement comprises a novel combination of l appliances wherewith the outlet-valve of the regulator is adjusted with Vreference to its seat, for the purpose vof permitting the operating current to iiow faster or slower; as occaslon requires, the details of this combinatraversed by the discharge passage b of a short neck or coupling t', the latter being screw threaded to enable the ready attachment of said regulator to any apparatus capable of being run with a Ilnid or gas. The top of this shell has an annular flange a that serves' as a seat for a flexible 'disk'or diaphragm C,
made of rubber or other suitable material,
said diskv being clamped at its margin by ay ring D, bolted to said flange, in the manner shown. Projecting upwardly from this ring, and converging inwardly, are ribs E, three being usually employed, and all of them being integralboth with said ring and a valvechamber F, the latter being sui-mounted by a screw-threaded cap f,;that retains av iianged inlet-pipe G in a proper positionL` gis a gasket interposed between the Bange ol' this pipe and the upper end of chamber'F.
His a stuffing box, screwed into chamber F, from its lower end, and tlaversedr by a Vsmooth pipe I, closed at top by a head z', which is counterbored to admit the inlet valve J. z" is a port in this pipe, below the head z'.
' Pipe I is connected to the upper end of a 6o box k, whose lower end takes the shape of a screw-threaded neck la, which, after passing Vthrough a circular orifice inthe center of disk C, has a nut L engaged therewith, a fiat washer Z being interposed between said disk and nut. Box K has/a cap 7c bolted to one side, and is traversed by a smooth pipe O, whose upper portion plays freely within the other pipe I, the lower end of said pipe O being closed by a head P that is counterbored 7o to admit the outlet-valve p. p' is a port in this pipe, above the head P. Screwed, or otherwise attached to that portion of pipe O included within the box K, is a lateral-lug R,
screw-threaded near one end to engage with an adjusting screw S. The upper portion of vthis screw passes' through a stuffing-box T, y
and has a square arbor s, ora thumb nut, that enables the ready turning of said screw either to the right orleft, as circumstances maysug- So `application'to the peculiar form of hydraulic air-compressor, lseen in Letters Patent No. 491,232, granted to me February '7, 1893. When -thns applied, the discharge passage b, of the regulator, is connected to the water inlet of the compressor byahose or tube, and the induction pipe G, is placed in communi cation with a street main, or other source of water supply. Valve p is then adjusted with reference to valve J so as to cause them to occupy the positions seen in Fig. l, when the diaf/ phragm C is in its normal condition, at which* roo time said diaphragm must be able to resistthe water pressurenecessary to runthe compressor at the desired speed. Now, when all the' p artsl are in their normal positions, it isfevident "rift" t EN,
water enters at the inlet G, flows freely around the valve J and head e', and thereby obtains access to the port t'. After passing through this port, the water traverses the communicating pipes I, O, escapes at the lower port p', fills up the shell A, and finally descends the passage b, and is then led to the inlet of the compressor. As long as the pressure remains constant, this flow of water will be continuous, but assoon as this pre-determined pressure is exceeded, the diaphragm C naturally bends or bows upwardly, and in so doing forces the valve J against the gasket g. Itis evident this automatic seating of said valve immediately shuts oft the flow of water through the regulator, which remains inoperative until the pressure beneath the diaphragm is reduced, and then the latter again resumes its norlnal position, the result being the free passage ot' fluid to the compressor, as above described. By properly turning the screw S, the pipe O can be adjusted either up or down within the other pipe I, for the purpose of causing the` valve p to approach nearer to its seat B, 0r to recede therefrom. When said valve is set quite near the seat, the water will be wire drawn on its way to the compressor, which latter will then run very slowly, while a greater opening of said valve will produce a corresponding increase in the speed of said compressor. be seen that the degree of pressure is determined solely by the action of the diaphragm C, and not by any shifting of the valve 1J, the duty of the latter being to regulate the velocity of the flowing current. Finally, by
turning the screw S until the valve p is seated, and then turning said screw still farther, nn-
It will thus f til the disk C bends upwardly, the valve .T will close the inlet G, and thereby stop the entire apparatus.
I claim as 4my invention-- 1. The combination, in a Huid-pressure regulator, of a shell having a valve-seat and discharge passage; a flexible diaphragm secured at its margin to said shell; a valvechamber provided with a seat and inlet; a valve occupying said chamber and carried by a tubular-stein, having a receiving port; another tubular stem fitted within the first one, and provided with an outlet-valve and delivery port; and a device for shifting the inner stem longitudinally of the outer one, whereby said outlet-valve is adjusted with reference to its seat, for the purpose described.
2. The combination, in a fluid-pressure regulator, of the shell A, having a valve-seat B and discharge passage l); a flexible diaphragm C secured at its margin to said shell, and having a box K attached to it; avalve chamber I11 provided with a seat g, and inlet G; a valve J occupying said chamber and carried by a tubular stem I, having a receiving port if; another tubular stem O Iitted within the one I, and provided with an outlet-valve p, delivery port p', and lug R; and a screw S journaled in said box and engaged with said lng, for the purpose of shifting the inner stein O, longitudinally ot' the outer stem I, all as herein described.
In testimony whereof I aiiix my signature in presence of two witnesses.
GEORGE H. VALKER.
