LEYVIS V. TRUESDELL, OF OXVEGO, NEWV YORK, ASSIGNOR OF ONE-HALF TO EMILY HEADLEY GERE, OF SAME PLACE.
FLUID-PRESSURE REGULATOR.
QPECIE'ICATION forming part of Letters Patent No. 337.461, dated March 9. 1886.
Application filed August 3, 1885.
T 0 all whom, it may concern:
Be it known that I, LEWIS W. TRUESDELL, of Owego, in the county of Tioga and State of New York, have invented a new and useful Improvement in Fluid-Pressure Regulators, of which the following is a full, clear, and eX- act description, reference being had to the accompanying drawing, making part of this specification.
My invention relates to means for regulating or reducing the pressure of fluids-such as water or gas-within the buildings into which they are introduced underpressure, sufficient, sometimes, in the use of the ordinary methods,
to endanger the bursting of the pipes and consequent injury to life or property; and it consists in the use of one or more elastic or flexible diaphragms, in combination with a Valve or valves adapted to be operated thereby, for
controlling the admission of the fluid to and the pressure of the same within a building, as will be explained, with reference to the accompanying drawing, which shows in vertical section an apparatus embodying my invention.
A represents the supply-pipe connecting with the street-main supply pipe or reservoir outside of the house, and terminating, by preference, in a valve-chamber, 13, arranged, by preference, within the house, the opening into 0 said chamber being covered by a valve, a. An ordinary lift or puppet valve of any suitable form may be employed. The chamber B is enlarged or expanded at its upper end at B into concavo-convex or dish form, and has an 3 5 elastic or flexible diaphragm, C, secured to and closing its upper and otherwise open end, as shown. This diaphragm has secured to it centrally a valve rod or stem, 7), which extends above and below the diaphragm, and has the valve asecured to its lower end. The rod or stem 1) moves with the diaphagm O, and, extending above the latter, has its upper end connected by a link, I), with the short arm of a lever, D, pivoted in a support, E. The
5 valve-chamber B has the house supply-pipe A connected with it, and the latter, at ashort distance from the valve-chamber B, connects, through a short pipe, f, with a chamber, F, covered, like chamber B, by an elastic or flexi- The long arm of lever D extends over the diaphragm O, and is pro- Serial No. 173.390. (No model.)
vided at its end d with a plate or shoe, cl, resting on said diaphragm, and adapting the lever to be moved or vibrated by it. The lever D has a series of perforations, (Z through any one of which it may be pivoted to the support E, for varying the relative length of its long and short arm, and therewith the amount of pressure on the diaphragm 0 required to operate the lever for closing the valve a and shut- 6o ting off the supply of water to the house supp y-p p The diaphragm-chamber F is of larger diameter than the chamber B, and its diaphragm G acts on the long arm of lever D, so that a smaller amount of pressure per inch, superficial area, in the pipes on the house side of valve (1 than is exerted upon the outer face of the valve serves to close the latter, and the pressure on the pipes within the house re quired for closing the valve can consequently be regulated at will by adjusting the pivot or fulcrum of lever D nearer to or farther from the actuating-diaphragm C; but it will be apparent that as soon as such inside pressure 1s relieved by the opening of a cock or sp1got, thcpressure of the fluid on the outer side upon the valve a will open the latter, and allow the supply to the house to be as full and free as though no pressure-regulating device were ap- 8o plied. As soon, however, as such cools or spigot is closed, the inside pressure rises 1mmediately to the point necessary to close the valve a, and then, further supply being out off, the pressure inside is prevented from rising to the objectionable point referred to.
The form of the valve, of the diaphragms, and of their connecting-lever and its support may of course be varied without departing from my invention.
Pistons moving in suitable cylinders maybe substituted for the flexible diaphragms, if preferred.
\Vhat I claim as new, and desire to secure by Letters Patent, is
1. In a fluid-pressure regulator, the diaphragm-chamber B B, provided with the fieXi; ble diaphragm O, the cutoff secured to and moving with the diaphragm-rod Z), passing through said diaphragm and secured therein, as described, in combination with the operating-lever D, having the horizontallymovable A and the house or distributing pipe A, of the valve a, diaphragm-chambers B and F, 15 and the diaphragms C and O, and the adjust able lever D, linked at one end to the dia phlegm-rod b, and provided at the other end with the presser-plate d, arranged and operatin g substantially as described.
In testimony whereof I have hereunto set my hand this 1st day of August, A. D. 1885.
