GAS-PRESSU RE REGULATOR.
SPECIFICATION forming part of Letters .Patent No. 241,057, dated May 3, 1881. Application filed April 19, 1880. (No model.)
To all whom it may concern:
Be it known that I, PERSON Novias, of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain Improvements iny Gas-Pressure Regulators, of which the following is a specification.
This invention relates to gas-pressure regulators for street-mains and other large pipes or conduits for gas in which the regulator is composed of a casing, through which the gas is adapted to pass, leaving a rigid valve-seat, a floating inverted cup or holder adapted to be raised or supported by the pressure of the gas intervening between the regulator and the burners, and a valve supported by and iloating with the holder and adapted to close upwardly against t-he valve-seat to shut oft' the flow of gas through the regulator. In this class of regulators it is desirable that the floating holder should exert a pressure upon the gas in the pipes between the regulator and the burners, and such pressure should increase as the quantity of gas passing increases, and vice versa, so as to compensate for the obstruction to the flow of gas resulting from the friction of gas on the pipes, the friction increasing with the quantity passing.
My present invention has for its object to assist the action of automatic machines of this class, and it also has for its object to control or tix the pressure of the floating holder at any desired point. To this end I make use of certain details of construction and arrangement of parts, which I will now proceed to more specifically describe.
In the accompanyingdrawings, which form part of this specification, Figure l represents a vertical section ot' an automatic gas-pressure regulator embodying my invention. Fig. la represents a horizontal section of the mercuryholder forming part of the compensator attached to said machine upon the line t m, Fig. l. Fig. 1l is a modification in the construction of a part of said machine. Fig. 2 represents a gas-pressure regulator of another form, embodying a portion of my invention.
In these figures the same letters refer to the same parts.
In the drawings, D represents a casing to be placed in the ground and connected with the gas-main. The arrows show the course of the gas into the inlet A, through the Valve B, and out from the outlet O.
E represents acasing placed in a building (in this case directly over the casing D) inelosing the oating gas-holder F, in form like an inverted cup. This gas-holder is provided with a water seal, zo, between its walls and the walls of the casing E.
g is a rod connecting the gas-holder F with the upwardly-closing valve B and its depending telescopic tube d. This rod has a tele scopic tube, d2, depending trom it, closed at its upper end, and projecting at its open lower end into a seal of mercury or other suitable fluid in an annular receptacle formed by two concentric tubes, d3 d4, through the former of which the rod y passes. The valve B has a telescopic tube, d, projecting downwardly into a glycerine or other fluid seal contained in an annular receptacle, a.
G is an automatic compensator attachment, for increasing thepressure of the oatin g gasholder F to any point desired. This compensator consists ot' the double-conical tube T, containing mercury, depending from the bar 7c, to which it is connected by the links u a. The bar 7c is connected at one end with the rod g, and it is pivoted upon the fnlcrum h, so that when tilted upon this fulcrnm the inercury may be transferred from one end to the other of the holder T, and so made to force down or lift up the gas-holder F and valve B, the operation being substantially as described in my pending application for Letters Patent for improvements in gas-pressure regulators file-d March 19, 1879.
It is apipe connecting the main pressure with the inside of the gas-holder F.
In apparatus of this class it has been the custom heretofore to include the main valve connecting with the gas-main and the iioating holder in one and the same casin 0'.
In my invention herein described I separate the valve and the floating holder, inclosing each within its own casing, and connect the valve with the holder by means of the rod g, as previously explained. By so doing it is possible to place the holder iu any of the upper stories ot' a'buildin g while the valve itself is located in immediate connection with the gas-main.
The operation of this apparatus is primarily such as is common in apparatus of' this class; but I make useof the following improvements:
In order to secure more perfect automatic action in the apparatus, I employ an improved form of valve-seat, giving it the form ofa truncated cone or ovoid section, j', whereby the fiow of gas through the valve may be more accurately and closely regulated. I also make use of the modified form (shown in Fig. ll) consisting of' the hemispherical valve-seatj", having its upper portion enlarged, as shown, it being apparent that a valveseat so formed will answer the same purpose as an ovoid valveseat,the object in either case being to demand a more considerable vertical motion of the valve when the How of' gas approximates a minimum, and less as it approaches a maximum, by which the transference of' the mercury in the holder T may be made to give any desired pressure for a given How of gas.
The pipe It is provided with a cock, 1J, and is also connected with an outlet-pipe, r, having the cock p. If an increased pressure is desired, a portion of the gas flowing into the holder is allowed to escape through the valve p and the pipe r, thus red ueing the pressure beneath the holder F and allowing it to descend and open the valve B, and so increase the pressure upon the gas in the pipes between the apparatus and the burners. The gas allowed to escape through the pipe r may be burned,if desired. The pipe 1" on the opposite side of the holder F may be similarly used as au outlet-pipe f'or increasing the pressure, if desired. By means of these ontlet-pipes r and r and their cocks p p2, the pressure of the floating holder may be controlled and fixed at any desired point independently of' the action of' the compensator G, and so rendering it possible to temporarily dispense with the use of' same; and the applica tion of' pipes so arranged to apparatus of this class forms an important part of my present invention. The outlet-pi pes also enable the valve to be suddenly opened to its fullest extent in eases of'emergency. In Fig. 2 is shown this part of my invention attached to a gaspressure regulator having a regulating gasllolder, F, in combination with an annular valve, as described in Letters Patent of' the United States No. 209,407, issued to M. W. Kidder, and dated October 29, 1878. Itis possible, by means of my invention so applied, to more exactly modify and control the action of the valve B and avoid the necessity for the compensator and weights heretofore used.
It is obvious that the pipe i may be in connection with the pipe R, as shown, or may be independent of' said pipe, as shown by r', as may be desired.
In eonstructin g the mercury-holder T, Imake use of the improved form more fully shown in Fig. l, the holder being narrowed at or near the middle thereof for the purpose of' preventing a sudden movement of' the mercury from one side to the other of the holder. This form of' the holder and the employment ofthe pipe R enable any desired form of' valve to be employed, as ovoid or Hat.
Itis obvious that my improved form of valveseat previously described is equally applicable to any form of regulator.
A pressure-regulatorconstructed on the general principles herein described may be used for steam, air, or water without other changes than those which would naturally occur to a mechanic in adapting it to the nature of the fluid or liquid, particularly when constructed as shown in Fig. 2.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-
l. The combination of' the valvechamber C, having a valve, B, the floating holderF in the casing E, the automatic compensator attachment G, the connecting-rod g, connecting the valve-fioating holder and compensator, and the pipe R, connecting the valve-chamber and the interior of the floating holder, and provided with an outletpipe, whereby the pressure of the floating holder may be controlled and fixed at any desired point.
2. In a gas-pressure regulator, the combination of' the valve-chamber D, containing the upwardly-closing valve B, having a sealed telescopic tube, d, the floating gas-holder F, contained Within the casingE, the supply-pipe R, the automatic compensator attachment Gr, and the connecting-rod g, having the sealed telescopic tube d2, substantially in the manner and for the purpose set forth.
3. In a gas-pressure regulator, the conoid or ovoid valve-seatf, in combination with an annular valve and a hollow liquid-loaded compensating-weight narrower at its center than at its ends, as set forth.
4. In a gas-pressure regulator, the outletpipe r, leading from the gas-holder and provided with the eock p', substantially as described, and for the purpose set forth.
In testimony whereof l have signed my name to this specification, in the presence oftwo subscribing witnesses, this 15th day of April, A. D. 1880.
PERSON NOYES.
