FREDERICK v. MATTON, OF CAMDEN, NEW JERSEY, AssIoNo TO THE CAMDEN IRON WoRKs, OF sAME PLACE.

PRESSURE-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 4,970, dated August 21, 1894.

Application filed January 18, 189d- Serial No. 497,284. (No model.)

To all tohom it may concern:

Be it known that I, FREDERICK V. MATTON,

of Camden, in the State of New Jersey, have invented certain new and useful Improvements-in Governor-Valves for Gas-Pressure Regulators, whereof the following'is afspeci fication, reference being had to the accompanying drawings.

.My invention relates to what are known as automatic pressure regulators, such, for instance, as the device shown and described in Letters Patent of the United States, No. 328,681, dated October 20, 1885; and the principal object of my improvements is to facilitate the movement of the valve nember in such an apparatus, while at the same time permitting it to completely out off the flo under certain circumstances.

It will of course be understood that the broad principle of construction, wherebythe -valve member is'moved in accordance with the demands of the distributing system, is.

not-'of my invention; but I have, for convenience of illustration, shown my improvements as embodied in a system whose main features,

ing upward. Fig. 4is a transverse section on the line 4., 4, of Fig. 2, looking downward. Fig. 5 is a detail View showing the method whereby the valve rod is attached to the actu ating device.

Referring to the general view of Fig. 1, A represents the supply pipe, communicating with the gas holder, or other reservoir of gas under pressure, and A the distributing pipe, the communication between said pipes being controlled within the valve-box, B, by means A of a movable valve attached to arod, g, which is suspended from a bell-float, G, partly submerged in water within a tank, H.

, Communication between the distributing pipe, A, and the interior of said bell-float is manner that the rise or fall of the bell-float occurs in conformity with increase or diminution of pressure in the distributing main,

the movements of the bell-float, in one direction or the other, actuating the valve in the direction proper for increasing or diminishing the flow of gas to the desired extent.

Referring now to the remaining figures, the nature of my improvements will be set forth. Within the valve-box, B, is a cylindrical valve chamber, 0, open at top and bottom, but connected with the wall of the valve-box by means of continuous vertical partitions, O, 0?, and a horizontal partition, 0 which partitions divide i the valve box into two compartments, one of which, b, is in direct communication with the supply pipe, A, the other compartment, d, being in direct communication with the distributing pipe, A; Lateral openings, I, 1', formed in the wall of the valve Chamber, G, afiord a direct communication between the interior thereof'and the compartment, d, while the valve chamber communicates directly atits lower end with the compartment, b. and indirectly at its upper end by means of the duct-B. The valve, F, which controls the communication, consists of a cylinder of sheet metal, having a closed top, f, and bottom, f, the latter of which isof slightly greater diameter than the cylindrical portion so as to afford an annular flange, f around the exterior. The cylindrical portion of the valve fits loosely within the valve chamber so that there is substantially no frictional Contact between it and the wall thereof.

' Lateral openings, E, E, are formed in the sides of the valve, corresponding in location with the openings, I, I respectively, in the valve chamber. A series of lateral openings,

J,is formed around the lower portion of the maintained by means of a pipe, 71., in such loo upper surfaceof the rim of the valve top, f, when. thetvalveis in its highest position, a close joint being also formed at the same time, between the flange, f ,'and the lower end surface of-the valve chamber, 0. e

The operation of the parts just described,

' is as follows: In the position shown in Fig. 2,

the valve is partly op'en,as the lower portions of the lateral openings, E, E, overlap the upper portions of the openings, I, I',in the valve chamber 0. The series of openings, J, isalso below the lower end of the valve chamber, and the gas flows freely through in the direction of the arrows. There being no frictional contact between the cylindrical portion of the valve and the wall of the casing, perfect freedom of movement isinsured, so; thatthe apparatus responds tovery minute changes of pressure within the distributing pipe,.and hence' insures delicate regulation. During. the period when the valve is open, there is of coursea slight leakage from the supply pipe-into the distributing pipe,.o,wing to the looseness of the fit between the valve andits chamber, but this may be disregarded,

as it has no practical effect during. the period of substantial flow. When, however, the,

valve rises so as to completely cut off the communication between the openings, E, E, and 1,1, the exterior flange, f will come into: close contact with the lower edge of the valve chamber, and simultaneously the outer rim ofthe top, f, will come into close contact with the flange, 0, making a practically close joint, the pressure'upon the respective ends of the valve being very nearly balanced under these circumstances,and the slight excess at the lower portion tending to insure closecontact.

To afford means for regulating very minutely the area of the valve openings, I provide the device shown in Fig. 5.

of said holes, the rod. is of course locked against horizontal movement; but by lifting the arm, N, so as to clear the stud, it, can be turned to rotate the rod, g, axially throughout a considerable arc. Such rotation of the rod ;will of course rotate the valve, F,,and will change the relation of the openings, E, E

the terms supply division and exit'division I indicate, respectively, the compartment, 6, of

the valve box in-communication with the-supply pip-e,.A,.and the compartment, d, of the valve-box in communication with the dis- .tributing pipe, A;

I claim- A gas pressure regulator systemcomprising supply and dischargepipes, anintermediate divided valve. box,.an actuatingvbell-float, a passage bet'weenthe bell-floatand the discharge pipe, a chamber in said valve box, said chamber communicatingat its side with the exit divisionand being open at its-lower end and supported ab'ove-the supply division, a valveclosed at its ends fitting loosely in said chamber and projecting below theopen bottom of the valve chamber, the valve having lateral openings in communication, respectively,- with thesupply division and the exit division, a flange at the lower end of saidvalve below the open endof, said valve chamber and adapted to make a close joint with the lower end of said chamber,a flange at the upper end of the valve chamber adapted to make a close joint with the upper end of the valve, and means whereby said valve is operatively connected with the actuating float, substantially as described.
