" EDWARD Ears, o E ROCHESTER, NEW YORK,- AssreNoR 0E TwomHlRDs HIS RIGHT TO R. E. SHERLOCK ANDv SAMUEL SLOAN, OF SAME `PLAGE.
IMPRovEMENT IN WATER-PRESSUREREG-minous.
Specification forming part of Letters Patent No. 172,877, dated February 1, 1876; application Vtiled May 3, 1875.
To all whom it may concern;
Be it known that I, EDWARD HAYS, of Rochester, in the county of Monroe and State of N ew York, have invented anew and useful Water-Pressure Regulator and I. do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, making part of this spccication, in which the ligure is a vertical central section of my invention. A The object of my invention is to provide a simple, cheap, and efcient governor to reduce and regulate the pressure of the water received into servicepipe's in buildings, &c., from the It consists in the employment of a xed cap arranged over the inlet-opening protector to the flexible diaphragm.
In carrying out my invention' in practice I provide a chamber, A, of any'desired size. At the bottom of this chamber, on one side, is arranged the inlet opening or pipe B, which is so formed as to constitute a separate compartment, as shown, to the center of the main chamber, whereit opens upward. This opening is .preferably `provided witha spherical valve, though any other form might be employed. This valve d is connected by a stem,
- ,I j', to a' flexible diaphragm, D, by suitable clamping-collars, a and c. Said diaphragm may be formed of rubber or of a thin metal plate.
.tis held in position by being clamped bevWeen the upper edge of the chamber A/and the convex cap or head F, which is secured to the chamber by the clamping-bolts s.
The cap F has a raised neck, fv, to act as a guide for the hollow follower b to move in vertically. The lever L is pivoted to the standard E fixed to the cap F, and rests across the spherical head c of the follower. The opposite end of the lever passes through the bifurcated standard H, also fixed to the 'head or cap F, and is provided with an adjustable poise or weight, G. The lower end of the follower or hollow stem b, it will.be seen, rests upon the metal washer c on the upperside of the diaphragm'. v Instead of this construction, however, the 'stem f, if desired, might be extended up to une lever L, and thus dispensewith the follower. In such a case the projecting bearing B, and the outlet-pipe (l to the distributingpipe.
When the cock in the supply-pipe is opened the water flows intol the chamber, and notbeing allowed to discharge therefrom it becomes filled,vand by the pressure through the supply-pipe the diaphragm and weighted lever "are forced toward the position indicated by the dotted lines, which change also lifts the valve d up into its seat r, thus cutting off any furthe]` supply into the chamberuntil a discharge-cock may be opened. This at once 'l reduces the pressure in the chamber, and the valve is thereby more orless opened, thus permitting a constantl supply to the opened cock 5 but as soon as that is closed the reaction occurs, and the valve is again forced into its seat, and held there by the extra pressure in the supply-pipe.
The valve d may be made of rubber, or other suitable material, and it may be made in any suitable form.
It will be seen that the greater the pressure required in the house, or the supply-pipes, the further the weight G should be placed from the fulcrum ofthe lever, and vice versa-that is, the notches on the lever should be numbered from the case A outward-the position of the poise or weight beingv adjusted with reference to the pressure required in the vdistributing-pipes, and without any reference to the pressure in the street-mains, which is varying.
The sudden reactionary force or strain upon the working portions of the regulator, especially upon the diaphragm, is almost wholly relieved by the employment of the air-chamber applied to the discharge-pipe C, as indicated by the full lines J 5 or, if desired, one
might be applied to the inlet-pipe, or to both the inlet and outlet pipes.
The cap mis designed to break the force m fixedtothe oase A directly over jtho inletof the upward ow of the Walter, and act as port,substantiallyfas and 'forthepurposes set a guard to protect the diaphragm from such forth.
force. E. HAYS.
What I claim as my invention is Witnesses: t In combination with the flexible diaphragm WM. S. LOUGHBOROUGH,
D, follower e, and Weighted lever L, the cap E. BQ WHITMORE.
