FLUID-PRESSURE REGULATOR.
SPECIFICATION forming part of Letters Patent No. 596,140, dated December 28, 1897.
Application filed February 3, 1897. Serial No. 621,878. (No model.) Y
To @ZZ whom t may concern:
Be it known that I, GEORGE GREENLEAF CLARK, a citizen of the UnitedStates, residing at Galveston, in the county of Galveston and State of Texas, have invented a new and useful Gas-Pressure Regulator, of which the following is a specification.
This invention relates to gas-pressure regulators especially adapted for use with gas stored under. high pressure in a cylinder or similar portable storage vessel. The regulator is interposed between and connected to the storage vessel and the distributing-pipes and automatically regulates the pressure of the gas in its passage from the former to the latter.
The object of the invention is to produce a device of this character simple in construction, efficient in operation, and which may be manufactured at a low cost and thereafter be easily kept in repair.
W'ith these objects in view the invention consists of the several details of construction and combination of parts hereinafter fully described, and particularly pointed out in the claims. p
In the drawings, Figure 1 is a vertical longitudinal section of the gas-regulator. Fig. 2 is a sectional view of a part ofthe regulator on the line a; .fr of Fig. 1. Fig. 3 is a view of a detached detail. y
Similar reference-numerals indicate similar parts in the several figures.
The chamber 1, its lateral extension 2, and downwardly-extending pocket 3 are all formed, preferably, in one casting, (indicated by 4.) That part of the casting in which the chamber 1 is formed is preferably cylindrical in horizontal section and is provided at its upper end with an annular iiange 5, to which is bolted a cap-plate 6 by means of the bolts 7, a gasket 8 being interposed betweenthe cap-plate and the iiange for the purpose of making a gas-tight joint. The cap-plate may be readily detached for the purpose of affording access to the interior of the chamber 1. That part of the casting which forms the extension 2 is preferably tubular in cross-secis formed in a depending part'of the casting,
and the pocket converges from its upper to its lower portion, thereby increasing the thickness of its wall at the lower part of the depending casting. This part of the casting is preferably cylindrical in cross-section, and its lower end is reduced and screw-threaded, as indicated at 15, forY the purpose of connecting the regulator to the storage vessel. The connection may be direct with the storage vessel, or a pipe may be used intermediate the regulator and the storage vessel, as circumstances may require. The threaded portion is provided with a passa-ge-way 16, through which the gas will pass from the storage vessel to the regulator.
17 represents a tapered' plug-valve seated in a suitable recess 18, extending transversely through the depending casting. The plug is held securelyin its seat by means of a washer 19 and a screw 20, the screw passing into the small end of the plug and the washer being interposed between the head of the screw and the outer wall of the depending casting, as clearly shown in Fig. 2. The plug-valve is provided with an opening 21, extending through it and adapted to register with the passage-way 16, and this opening is enlarged and threaded at one end. A lever 22 is threaded at its lower end vinto the enlarged portion of the opening 21 in the plug-valve 17, and this lever is provided with a longitudinal bore 23, extending longitudinally of the plug for some distance, where it communicates with an opening 24, extending transversely through the lever. The longitudinal opening in the lever communicates with the opening in the plug, and a passage-way is thereby formed for the gas from the storage vessel into the chamber 1. The upper end of the lever 22 is reduced, as indicated at 25, and the reduced portion is provided with an elongated opening 2G.
27 represents a rod having a threaded end which passes through the diaphragm 12 and is iirmly secured thereto by means of the nuts 28, one on each side of the diaphragm, and the metal washers 29 and rubber washers 30, the washers being interposed between the nuts and the diaphragm, as clearly shown in Fig. 1, for the purpose of making a gas-tight joint where the rod passes through the diaphragm. The other end of the rod 27 is T- shaped, as indicated at 31, and this T-shaped end is secured to one end of a reversely-bei1t plate-spring 32, the other end ofV said spring being iirmly secured to the wall of the chamber 1 by means of bolts 33 and nuts 34, suitable washers 35 being interposed between the nuts and the wall of the chamber to form a gas-tight joint. The rod 27 is provided with a slotted opening 2G, through which the reduced end 25 of the lever 22 passes, and a pin 37 extends through the rod 27 and the opening 26 in the upper end of the lever 22. The tension or power of the spring 32 will be such that the spring will maintain its normal position until the pressure of the gas in the chamber 1 exceeds a predetermined pressure of the gas inthe service-pipe; but as soon as the pressure in the chamber 1 exceeds this predetermined pressure in the service-pipe the spring 32 will yield to the action of the diaphragm 12, caused by the excessive pressure, and permit the rod 27 to be moved in order to close the valve 17 to cut oit` the supply of gas.
3G is a pipe leading from the chamber 1 to convey the gas to the service-pipes.
The flange 5 and cap-plate G are perforated, as indicated at 37, for the reception ot' bolts, by means of which the regulator may be secured to any suitable support--as, for instance, the bottom of a railway-car.
The operation of the device is as follows:v
The regulator having been properly connected to the storage vessel and the service-pipes, gas is admitted from the storage vessel through the passage-Way 16, plug-valve 17, bor 23, and through the transverse opening 21 into the chamber 1, and the pressure of the gas in the chamber 1 will soon be equal to that of the gas in the storage-reservoir. Then this pressure is in excess of what is required in the service-pipes, the diaphragm l2 will be forced outwardly and the spring 32 will yield, thereby moving the rod 27 to the left and causing the lever 22 to turn the plugvalve 17 in its seat to close communication between the storage vessel and the chamber 1. As the spring 32 will be of such tension or power as to permit the diaphragm l2 to move outwardly only when the pressure in the chamber 1 exceeds the predetermined pressure of the gas in the service-pipes, it is obvious that as the gas is consumed at the burners connected with the scrviee-pipes the pressure in the cylinder will be reduced, and the spring 32 will then retract the rod 27 and thereby shift the lever 22 to cause it to open the plug-valve 17 and again permit the gas to ilow from the storage vessel into the cylinder.
It will thus be seen that the regulator automatically controls the pressure of the gas in the service-pipes, that the construction is simple, and that it maybe easily taken apart for the purpose of repair or the renewal of any of its parts.
1t will be understood that changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any ot' the advantages of this invention.
Having thus described my invention, what I claim is 1. In a gas-pressure regulator, the combination with a chamber adapted to be connected to the source of gas-supply, and a turning-plug valve in the gas-conduit between the chamber and source 0f supply, of a lever connected to the plug-valve and having a passage-way formed therein to establish communication between the passage in the plug-valve and the chamber, a rod connected intermediate its ends to the lever and one of its ends being T-shaped, adiaphragm within the chamber to which one end of the rod is connected, a reversely-bent plate-sprin g secured to the wall of the chamber and to the T-shaped end of the rod, and a service-pipe leading from the chamber substantially as described.
2. In a gas-pressure regulator, the combination with a chamber adapted to be connected to the source of gas-supply, and a turning-plu g in the gas-conduit between the chamber and source of supply, said plug having a transverse opening threaded at one end, of a lever secured at one end in the threaded portion of the opening in the plug-valve and having a passage-way formed therein to cstablish communication between the passage in the plug-valve and the chamber, a diaphragm within the chamber, a rod having a spring-support at one end and connected at its other end to the diaphragm, said rod also having a pin-and-slot connection with the upper end of said lever, and a service-pipe leading from the chamber, substantially as described.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
GEORGE GREENLEAF CLARK.
