FLUID-PRESSURE REGULATOR.
SPECIFICATION forming part of Letters Patent N o. 662,550, dated November 27, 1900.
Application iled November 8, 1897. berial No. 657,862. @lo model.)
To a/ZZ whom t may con/cern.-
Beit known that I, HENRY O. SISCO, a citizen of the United States, residing at Anderson, in the county of Madison, State of Indiana, have invented certain new and useful Improvements in Fluid-Pressu re Regulators, of which the followi ng is a specication, reference being had therein to the accom panyiug drawings.
This invention relates to fluid for pressureregulators, and has for one object to produce an improved form of apparatus for actuating the main regulator used in fluidpressure sysw tems of various ch aracters, whereby the necessary pressure may be maintained in the pipelines under varying conditions of use.
It has further for its object to arrange the auxiliary device so that the same will be operated by the decrease orincrease of pressure upon the pipe-lines at a point distant from the main regulator of the system-for instance, at the point in thesystem where the iluidpressure will be the lowest.
A further object is to improve the device for actuating the regulator so that the same will operate without friction and will not be affected by changes in temperature to which the main regulator may be subjected.
Other objects and advantages of the invention will hereinafter appear in the following description and the novel features thereof will be particularly pointed out in the appended claims.
In the drawings, Figure l represents a side elevation of the main pressure-regulator and the auxiliary device applied thereto. Fig. 2 is a vertical section of the auxiliary device with thelever of the main regulator and other parts in elevation. Fig. 3 is a diagrammatic view of the pipe-line system, showing the location of the main regulators and the auxiliary device for actuating the same; and Fig. 4 is a central section through a preferred form of main regulator used with my auxiliary device.
Like letters of reference indicate like parts throughout the several figures of the drawings.
The letter A designates the main pipe of a fluid-pressure system, in communication with which are a number of distributing pipe-lines A. The main pipe is provided with any preferred form of regulating device B, which has been illustrated in this case as provided with a stem B', extending upward from the regulator-diaphragm, with the lever B2 pivotally mounted upon the support B3 and pivotally connected with the stem Bl. At the other end of this lever a suitable weight B4 is provided, which may be adjusted to regulate the amount of fluid to pass through the regulator under ordinary conditions of use. A suitable shutolf cock or valve A2 maybe applied to the pipe-line adjacent to the regulator, if desired.
The parts just described maybe of any desired form and such as are ordinarily used in an apparatus of this character.
An illustration of the preferred form of main regulator B is shown inFig. 4, wherein the stem B is connected with a diaphragm within the regulator, which diaphragm by means of an extension Biand connecting-lever B7 operates the regulating-valve BS. The weight B4 is properly adjusted to permit the diaphragm B5 to operate the valve for the purpose of maintaining the propel' normal pressure within the system.
The system provided with a regulatorjust described will admit a certain pressure of fluid into the main, which pressure will be gradually diminished by the use of the fluid from the mains until at a point distant from the main supply of the system the pressure will be at its lowest. For instance, at a central point, as indicated at A5, the pressure of fluid will be very much lower than at any other point. For the purpose of maintaining the pressure throughout the system equal, or, in other words, to supply an equal amount of duid at the point A3 as at other points in the system7 l have applied a return-pipe O, which extends toward the regulator B and is connected with the auxiliary device D.
The device comprises a closed chamber vided with a collar E, upon which will rest a series of weights E when it is found necessary formed of two parts D', having secured be- IOO - to apply further Weight to the main lever of the regulator B, and when these weights are so applied a greater pressure of gas will be permitted at the point A3 in the system. The return-pipe C of the system may be provided with any suitable cock or valve C' for the purpose of reducing the amount of fluid passing through this pipe or for shutting the pipe oi -for use.
From the foregoing description it will be observed that the lowest pressure of fluid in the mains will be at the point A3, which is at the greatest distance from the source of supply, and that the small return-pipe will conveyto the auxiliary device the pressure of fluid at the point A3. If` this pressure be less than the proper amount determined upon for the mains, the diaphragm-rod of the auxiliary device will fall and in its movement opcrate the valve .of the main regulator to admit more fluid into the system, while, on the other hand, after the pressure reaches the predetermined amount at the point A3 the same pressure will be communicated to the diaphragm and through its connections operate the regulator B to close the valve thereof and admit less fluid into the system. It will be observed that by this means a uniform pressure is automatically maintained at the point of' lowest pressure in the system, and the auxiliary device for the main regulator is so constructed that no stuffing-boxes are necessary, and as no liquid is contained therein all danger of freezing is avoided. The device is `thus very sensitive in operation and accommodates itself and the main regulator to all differences in pressure caused by the use of varying amounts of fiuids carried in the system. It will be understood that in Fig. 3 the return-pipes C extend to opposite ends of the system, as it is customary in systems ol this character to supply the iiuid from each end of the main pipe, so as to maintain as far as possible an equal pressure therein. After the main regulator B is weighted for the proper pressure of duid-ordinarily required in the system this auxiliary device Will control any excess or decrease of the pressure,- which will be mos-t prominently felt at the point A3 in the system, which is usually in the center of the city or town and Where the usual pressure-gages are located for determining the lsupply provided for the system. In the event that more fluid should he required for the main than that for which the regulator Bis set the pressure can be increased at the central office A3 by means of the stop cocks or valves C in the return-pipes, which will reduce the pressure therein and cause the auxiliary device to open the valve of the main regulator B.
It is obvious that numerous changes may be made in the construction and arrangement of the several. parts without departing from the spirit of' this invention as defined by the appended claims.
Having described my invention and set-` forth its merits, what I claim as new, and desire to secure by Letters Patent, is-
l. The combination with a su pply-pipe provided with a main pressure-regulator having an operating-lever under tension connected therewith, of an independent auxiliary regulating device under tension and comprising a chamber having therein a diaphragm, a rod carried by said diaphragm and extending therefrom, means detachably connecting said rod to the outer end of' said regulator-lever to increase a fluid-supply, and a return-pipe extending from the supply-pipe from the regulator on the' service side thereof at a low-pressure point of the same into communication With the diaphragm of said auxiliary device; substantially as specified.
2. The combination with a su pply-pipe provided with a main presstue-regulator and having a weighted lever connected therewitlnof an independent auxiliary regulating device comprising a chamber having therein a diaphragm,an upwardly-extending rod from Said diaphragm, an adjustable tension device carried by said rod, an adjustable lug on said rod removably connected with the outer end of' said lever to increase a fluid-supply through said regulator, and a return-pipe extending from the supply1pipe at a low-pressure point of the same into communication with the lower portion of said auxiliary device; substantially as specified.
In testimony whereof I affix my signature in presence of two witnesses.
