PRESSURE REGULATOR.-

NiTnD STATES PATENT OFFICE.

JOSEPH ROTHOHILD, OF BROOKLYN, NEW YORK, ASSIGNOR OF THREE- FOURTHS TO GEORGE W. RENTON, ROBERT-L. ORANFORD, AND GEORGE O. ORANFORD, OF SAME PLACE.

PRESSURE-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 505,850, dated October 3, 1893.

Application filed .Tune 16, 1893. Serial No. 477,802. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH ROTHCHILD, of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Pressure --Regulators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention has relation to that class of devices or machines known as pressure regulators and employed to control the pressure of liquids or liuids which may How through or past the devices, to prevent damage, to insure uniformity of pressure, and for other valuable offices in connection with the medium operated upon.

Among the objects of my invention are the production of a machine of the class above named, which shall be of few and simple parts capable of easy, accurate and certain operation by the action of the liquid or iiuid,-to provide for easy adjustment ot' the valve to compensate for any wear after long use,-to prevent the incoming pressure from tightening the Valve in its seat-,-to provide a single and ready means of regulating the pressure 'at which the liquid or fluid may be discharged and of changing this pressure atvwill,-and to secure certain advantages and economies in the construction, operation and use of the machine, as will be herein first fully described and then pointed out in the claims.

In the drawings, Figure l is aside elevation or exterior view of my improved pressure regulator. Fig. 2 is a vertical section and elevation upon a plane through line fr-x of Fig. l. Fig. 3 Vis a horizontal section through the axis of the valve; and Fig. 4 is a cross section through the valve and casing.

In all the figures, like letters of reference, Wherever they occur, indicate corresponding parts.

A is the main shell (containing the valve) and B the inlet and O the outlet openings for liquids or fluids at which any pipes or other vessels may be applied. Within shell A is a valve casing D of smaller diameter thanl said shell, leaving a free channel ct between these two parts, into which channel the liquid or iuid is forced from theinlet. The casing D is very slightly conical on its interior and it is held in place against an abutment as b upon which it is crowded or packed by the end plug c which contains the outlet O.

E is a hollow, rotary valve, accurately ground into its casing or shell D, the valve and casing being correspondingly perforated on opposite sides, as atd and e. in its seat against longitudinal movement by a screw boltf passing through its closed end and entering a hollow internally and externally threaded plug g screwed in the end of casing D. The plug g is easily reached and turned through the inlet B, and it is set so as to bear against the end of the valve when the latter is properly seated. Then the valve is locked or held against the plug by bolt f, which is easily reached and turned through the outlet. When the valve after long use moves back a trifle and the boltf again tightened. The valve turns easily and smoothly on bolt f so as to avoid unnecessary friction at this part. The valve being slightly conical, largest toward its delivery end, and being perforated on opposite sides, external pressure on the valve through ports e will be balanced, and

this pressure instead of crowding the valve.

tighter in its seat, will tend rather to loosen it, so that under all pressures the valve may be moved as easily as may be desired. Liquid or iiuidunder any pressure enters at the opening B, passes around casing D, through ports e and d (when they are opened), into the inner cavity of the valve and out at the larger open end thereof.

To automatically turn the valve so as to arrest or check the liow of liquid or iiuid, and to make this turning correspond with the pressure produced by the outgoing medium,

` I connect the valve with a diaphragm which is exposed to and operated by the pressure of said medium.

Upon one side of shell A (and preferably cast therewith as shown) is a cup shaped enlargement F, serving as a seat for a diaphragm v G, the inner cavity H communicating with the interior of shell A through a suitable opening in advance of the position of the The valve is held .7G loosely in its seat, the plug g may be turnedY IOO ports through the valve and casing. The diaphragm G is held in place by a bolted cap or cover H2 and is supplied with a stem I eX- tending above and below it and suitably secured by a ledge h and nut i. Around the upper part of stem I and within neck H of cap H2 is a spring K bearing upon nut i at one end against a regulating screw k at the other. The screw k is threaded into the upper part of neck H', and by turning this screw the amount of pressure upon the upper side of the diaphragm can be regulated at Will, as will be readily seen.

To connect the valve E with stem I, I employ a rod Zwhich is threaded at one end into the material of the valve, passes through the opposite side of the valve and into a cylinder or block m which is seated in the lower end of stem I so that it can turn freely therein. When the valve is moved longitudinally in its seat to loosen or tighten it, the rod Z moves with it, and the block fm being loosely mounted, will slide longitudinally in its seat to accommodate itself to the changed position of the rod so as to avoid all cramping or binding and unnecessary friction. The

rod Z is adjusted to place by removing a plug n, which is afterward replaced. Under the construction explained, when the diaphragm rises or falls, the valve is rotated in its seat through the medium of rod Z and its connections. medium entering the regulator should leave it with one-half its initial pressure. The spring K has then only to be adjusted so that the diaphragm will rise suliciently to close the valve as soon as the pressure beneath it reaches the determined point.

The valve is normally open. the liquid or uid on the outlet side of the regulator is considerably below the required degree it may continue to How, but as soon as this pressure commences to increase the valve commences to close, and when the predetermined pressure is reached the valve arrests all further flow and automatically opens upon any diminution of pressure. Any desired difference in degree of pressure between the Suppose it be desired that the So long as incoming and outgoing medium may be provided for by varying the tension of the spring.

The working parts of the valve being completely covered and the atmosphere excluded by the main shell, expansion and contraction of Working parts are equal and they will therefore work easily and without sticking as would otherwise occur.

The improved regulator is especially well adapted for use in connection with domestic and other plumbing, operating to arrest the iiow of water from the main the instant the pressure on the outlet side of the apparatus reaches a determined degree,but it maybe used in other situations as well.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a pressure regulator, the combination with the hollow valve and its casing located within the outer shell, of the hollow, threaded plug passing through the valve cage and the screw bolt passing loosely through the valve and engaging the screw plug, the parts being arranged to adj ust the valve to its seat within the valve casing and being accessible, the one from the exterior through the inlet port and the other from the exterior through the outlet port, substantially as shown and described.

2. In a pressure regulator, the combination with the hollow, rotating valve and means for adjusting it in its seat, of a rod secured thereto and extending at right angles to the axis thereof, the stem connected with the diaphragm and a block mounted and turning in the lower end ot said stem and capable of adjustment at right angles to the seat, the rod entering the block and serving to transmit motion from the diaphragm to the valve, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto setmy hand in the presence of two witnesses.

JOSEPH ROTHCHILD.
