IMPROVEMENT IN WATER-PRESSURE REGULATORS.
. Specification forming part ofLetters Patent No. 176,791, dated May2, 1876; application filed March 3, 1876.
regulating the pressure of the water .in service-pipes. It consists in the employment of an adjustable spring in connection with a flexible diaphragm, which is connected to the governing-valve, and of a peculiar construction of such valve.
The valve case or shell A is threaded through the bottom to receive the stem B of the valve-stock. The lower or outer end of this stock is somewhat reduced in diameter, and threaded to receive the pipe from the main. It may be provided with an octagonal section, as shown at b, upon which to apply a wrench. Its upper'e'nd is formed with a flanged cap or head, h, through which there is no vertical opening. The stock is screwed into the case from the open end before thediaphragm is applied. There are several small lateral openings, 0', near the head it through the stock. The enlarged portion or section below the head is provided with an an nular vertically-sliding valve, G, which is nicely fitted thereto. There may be a slight groove turned next to the head h, into which is sprung a rubber or other cushion, a. The valve 0 is connected on two opposite sides at g, by trunnions or otherwise, to the yoke 31 of therstem F. This stem passes through the diaphragm D, to which it is secured by a suitable collar above and below, and the clamping-nut d. The diaphragm is attached to the open or upper end of the case A by means of the ring R and several clamping-screws. The lower ends of the posts P answer for two such bolts or screws. The upper portion of these posts is threaded, as
shown, and the cross-bar G is fitted loosely upon them, and secured thereto by the setnuts a. Before the bar is placed in'position the spring S is. applied to the stem F, the lower end against or upon the nut d, and its upper end against the bar, as shown. The tension of the spring, or its force upon the diaphragm and valve, may be regulated to-any desired extent, and with the greatest nicety, by the nuts n.
The openings 6 may be oval-shaped or oblong squares, 1f desired, the narrow way being vertical, which would effect a greater change in the flow through the stock with agiven movement of the valve. The diaphragm may be composed of any suitable material.
The inlet-pipe is attached at E, and the outlet or service pipe at J. It will be seen that when no cock on the service-pipes is open the pressure against the diaphragm will force it upward,.so as to close, or partially so, the valve, which reduces the pressure in the pipes within the building. The relative pressure in the service-pipes with relation to that in the main may be increased by increasing the tension of the spring, which is done by turning the nuts a farther down upon the posts, and vice versa.
To avoid mechanical fitting between the stock B and the annular valve 0 the lower end of the latter may be provided with a rim projecting inward, and the former have a corresponding shoulder for this rim to strike against. buch rim should be cushioned, the same as the upper end now is, against the v head It. This would prevent the possibility of leakage when the valve is forced up to cut off the passage of the water. It will be seen that the pressure of the water upon the valve, being lateral, can have no tendency whatever tomove the valve vertically.
What I claim as my invention is 1. As an improvement in waterpressure regulators, the valve 0 and inlet and outlet water-passages, in combination with an adjustable spring, S, and flexible diaphragm, the valve and diaphragm being connected together, whereby the slightest movement of TENT OFFICE.
the latter shall produce a corresponding the outside of the seat, and constructed to be movement of the valve, as and for the puroperated substantially in the manner and for poses set forth.
2. In combination with a hollow cylindrical valve-seat, having its upper end closed by a Witnesses: head, h, and provided with lateral openings 2', WM. S. LOUGHBOROUGH, the annular balance-valve 0, arranged upon B. O. WILLIAMS.
the purposes set forth.
