Specification forming part of Letters Patent No. 159,732, dated February 9, 1875; application tiled January 14, 1875.
To all whom it may concern:
Be it known that I, FREDERICK W. WIEsE- BROCK, of the city and county of New York and State of New York, have invented an Improved Gas Regulator or Governor, of which the following 1s a full, clear, and exact description, reference being had to the accompanying drawing, and the letters of reference marked thereon, making part of this specification, in whichl Figure 1 is a vertical sectional view. Fig. 2 is a vertical sectional view of a modification of Fig. l. Y
The nature of my invention consists in arranging, at or near the head of a supply-pipe, the valve-seat, through which passes the valverod, to which is attached an ordinary pressurevalve and a plunger, the same working, as it were, in a chamber formed at the elbow of the supply, and in the hollow section of a screwcap attached thereto. The plunger and the interior surface of the screw-cap are so finished as to provide a ground joint, which effectually prevents the ingress or egress of gas through said joint; or, instead of the ground joint, an elastic diaphragm may be used. The great advantage of this arrangement is found inV the fact that while the full force of the pressure from the gas-containing vessel which the supply-pipe may feed would act with a tendency to close the valve and keep it in that condition, yet, owing to the arrangement of the plunger in connection therewith, the effect ofthe pressure of the gas on the valve is neutralized, leaving the same free to be automatically opened and closed entirely, irrespective of the varying pressure of the gas in the supply-vessel or meter.
The nature of my invention also consists in attaching to the valve-rod another plunger, the same being so finished, in connection with its bearing-surface, as to provide a ground joint, and so arranged that, through a regulated pressure on its upper surface, and the pressure of the gas on its lower surface, it shall allow any desired quantity of gas to be fed, and yet, as either of the adverse pressures predominate, to automatically open and close the valve, precisely as in my former patents.
The construction and operation of my inven. tion are as follows:
A is the shell ofthe regulator, and is of any desired form, and is constructed of any suitable material, and is formed with interior annular bearing-shoulders A1 A2, against which are screwed the end pieces B B. Tight joints are formed .between the female screw-threads of the shell and the screw-threads of the end pieces by means of washers or other suitable packing a a. One or both of these washers, if desired, may he in the form of an elastic diaphragm, secured between said screw-threads. O is the inlet-pipe, and is designed to be attached to the gas-containing vessel or supply; and O1 is the discharge-pipe, and is attached to the vessel in connection with which the regulator is used, and to which it is designed to supply the gas as occasion requires. The supply-pipe O terminates in an elbow-shaped section, O2, which, at its lower surface, is provided with a female screw-thread, into which is screwed the cap D. The interior surface of the elbow-section G2 of the pipe O and the interior surface of the screw-cap D form the walls, as it were, of a vertical chamber, through which travels the valve rod or stem E, and in which works the movable valve F and plunger F. c is an opening or orifice in the upper seetionof the supply-pipe C, and constitutes the seat of the valve. The walls of this orifice are slightly beveled, curved, or of such other contour as will correspond to the form of the pressure-valve F. d is a washer or elastic diaphragm, inserted between the screw-threads at the lower sect-ion of the supply-pipe O. At the lower section of the screw-cap D is an opening, D', which leads to the chamber within the shell, and through which gas passes to the under surface, of the plunger B and the pressure within the same, when the gas-chamber is sufficiently charged, so acts on the plunger as to assist in closing the valve. E 'is a rod or stem; and F is a pressure-valve, secured to the same; and F', the plunger, which is screwed onto the lower section of said stem.
In manufacturing, the outer surface of the plunger F and the interior surface of the hollow screw-cap D are so nished bythe ap-` plication of the Hour of emery and oil, brother equivalent substances, that when tted to` gether they shall form a ground joint, or the washer d may be of the nature of an elastic diaphragm, in which case it would form aexible tight joint, in connection with which the rod E and plunger F would act. H is also a plunger, and, when the device is constructed as illustrated in Fig. l, is designed to antomatically open and close the valve through adverse pressure on its opposite surfaces, precisely as in my patent of January 12, 1875, No. 158,768. This plunger also is secured to the rod E, and operates in connection with bearingsurfaces h 7i, which extend down from the shoulder A. This plunger H and its bearing-surface 7L 7i, in being manufactured, are also so finished as to provide a groundjoint, or the washer a may be in the nature of an elastic diaphragm, and in which case it would form an elastic joint. The rod E is secured to the plunger H and elastic diaphragm a, when one is used, by means of a screw-cap` bearing, e, or other suitable device. E is a spring, and is secured around the rod E, and has its seat on the upper face of the screwcap connection c, and its upper bearing on the inner face of the screw-cap K. K is a ring or equivalent device secured to the upper section of the rod E, and serves to prevent the screw-cap K being detached, and also to permanently close the valve when desired, which is effected by screwing up the cap against the same, and which not only relaxes all the'tension and pressure of the spring, but lifts the rod so as to draw the valve against its seat. The spring E', as illustrated in the drawing, is a coil-spring, but ofcourse any other spring suitable to the purpose might be substituted in its stead, or the spring might be dispensed With, and the degree of pressure which the plunger is designed to resist without elevating the same so as to close the valve might readily be regulated and adjusted by means of weight-s or a Weighted lever. The arrangement of spring E', rod E, plunger H, and screw-cap K is precisely the same, excepting the ground jointv of the plunger, as the arrangement of similar devices described and claimed in my patent before referred to. In Fig. 2 is shown a modiication of the device as illustrated in Fig. l, the only dierence being that the plunger H is dispensed with, and the plunger F so enlarged as to prevent the requisite surface for the pressure of the gas to act against, so as to close the valve so soon as the pressure of the gas within the chamber of the shell reaches that degree at which it is desired the valve sh'ould close.
,It will be observed in my present improvement that I have departed from the principle )f my former inventions of this character, and which is the leading and distinguishing fea- ;ure of the device embraced in and covered Jy Letters Patent of the United States, num- )ered, respectively, 158,767 and 158,768, and
which were issued to me January 12,1875,
and also of the device embraced in an application for a patent tiled even date herewith, and which is to so arrange the valve that Wh en the sameis closed, and the gas in the supplyvessel is turned on, although it is in direct contact with the upper face of the valve, owing to theexceedingly small eye of the discharge-orifice in said valve-seat, the gas shall be practically inoperative to open the valve, no matter what the degree of pressure of the gas in the supply-vessel may be. v In my present improvement this arrangement of the valve inconnection with its seat is reversed, and is so arranged that the pressure ot' the gas acts directly on the under face of the valve, and, consequently, if this pressure was not neutralized, it Would continually be exerted to close the valve, and to keep it in that condition after being closed.
`To neutralize this pressure on the valve,vand
to leave the same free to act through adverse i pressure on the opposite faces ot' a plunger, is the chief design of this invention, and which enables me to construct a regulator suitable to charge the large vessels of brewcries, &c., and where a correspondingly large quantity of gas is desirable. f From thetoregoingfull and detailed description the operation of my present improvement in gas-regulators Will readily be understood. The regulator being connected by the pipe C to the gas-supply vessel, and by the pipe G1 to the vessel which it is designed, as occasion requires, to charge, the cock is opened, so as to turn on the gas from the supply-vessel. The valve F, owing to the Weight of the plunger or )lungers valve-@carinop and tension of the 1 a 7 a ma spring when the same is exerted, is, in its normal condition, open. The gas-supply vessel being charged to a high degree, the first flow of gas which rushes through the pipe C would have the tendency to close the valve, and, in ordinary regulators, Where valves of this character are used, would do so, unless the regulator was so adjusted as to resist a pressure equal to, or nearly as great, as that contained in the supply. To so arbitrarily set or adjust a regulator as to accomplish the object my regulator is designed to effect is impracticable, for my regulator when in operation, in connection with a supply-vessel and a vessel contain-` ing ale, lager, &c., is constantly called upon to supply varying quantities of gas, and is fed from a supply whose pressure is constantly va` rying in degree. Therefore it is essential that the valve should be purely automatic in operation, and, under all circumstances, remain practically unaffected by the pressure in the supply-vessel. The pressure from the supplyvessel on the under surface of the valve F I neutralize by means ofthe plunger F', as will be readily understood. The gas,rushingin through the pipe C, will exert pressure on the valve F in au outward direction, and with a tendency to close the valve; but the same pressureis also exerted on the plunger F. Now, it will be seen,thesc different pressures operate in an opposite direction, and, as the valve and plunger are so connected as to operate, under pressure, iu opposite directions, and, as it were, as a balance-valve, it will be seen that the pressure on the one is, in a great degree, neutralized by the pressure on the other, which leaves the plunger free to act through adverse pressure on its opposite surfaces, the pressure of the spring or weights, in connection with the weight of the plunger H, supplying the one that opens the valve, and keeps it open, and the adverse pressure of the gas on the under surface of said plunger, and the supplying the other plunger, F', and thus automatically the valve is opened and closed,as occasion requires,
precisely as in my former inventions.
The modification represented in Fig. 2 operates, in all respects, substantially similar to the device illustrated in Fig. l. The plunger H is dispensed with, and the plunger F' is so enlarged as to possess the additional function that, through the pressure of gas on its under surface when the desired degree of pressure exists Within the chamber of the regulator, the valve shall be automatically closed, and again automatically opened so soon as the discharge of gas through the pipe C1 so reduces the pressure as to render it less than the sprin g or weighted pressure on the opposite surface of the plunger. The spring E or Weights are only designed to regulate the degree of pressure which the plunger shall resist before being so operated as to close the valve.
What I claim as new, and desire to secure by Letters Patent of the United States, is-
1. In combination with a shell or case, A, the inlet-pipe C, valve F, and plunger F', arranged as shown, whereby while the pressure of the gas in the supply-vessel acts with a tendency to close said valve, the same shall, in a great degree, be neutralized, substantially as described.
2. The valveF, plungers F H,provided with ground or elastic joints, and connected to the rod E in the manner shown, in combination with the supply-pipe C and opening or valveseat c, the whole being constructed and arranged to operate substantially as described.
3. In a pressure-regulator, a suitable shell or case, having a supply-pipe, C, and dischargepipe G1, stem E, valve F, plungers F H, provided with ground or elastic joints, spring Ef, and screw-cap K,the whole being com bined and arranged to operate substantially as described.
In tcstimon y whereof I have signed my name to this speciiication in the presence 'of two subscribing witnesses.
