WATER-SUPPLY VALVE.

SPECIFICATION forming part of Letters Patent No. 238,504, dated March 8, 1881.

Application filed June 18, 1880.

To all whom it may concern Be it known that I, PATRICK HARVEY, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Water-Supply Valves; and I hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art to which my invention appertains to make and use the same, reference being had to the accompanying drawings, forming a part hereof, in which- Figure 1 represents a vertical central section, with the valves in position for supplying Fig. 2 represents the same with the valves closed against the main or supply, and discharging the water above the same into the waste.

Like letters of reference indicate like parts.

The object of my invention is to provide a water-supply valve for water-pipes and hydrants tha may readily and easily be operated from any desired place, and which shall be less liable to wear and consequent leakage than the check and waste stop-cock commonly used; and my invention consists in combining with a water-supply or main valve, acheckvalve which controls the operation or action of the main valve by means of the water-pressure, substantially as herein shown and described.

In the drawings, A represents the casin gformingthe chambercontainingthe operating parts, to the lower end of which is screwed a cap, 0, provided with an inlet or induction, T, and to the upper end is screwed a cap, B, provided with a chamber containing the valve and a tubular stem, N, through which passes the stem of the valve W, to thelower end of which is attached a valve, k, provided with a packing, 0, to fit against the valve-seat k at the lower end of the tube N. The opening of the chamber of the valve k is closed by a rubber diaphragm, f, and said diaphragm is held in place by the cap B screwed upon it, as shown. Through the cap B passes a stem, L, the lower end of which is provided with a broad foot resting upon the diaphragm f. The casing A is also provided with an outlet or eduction, a, to which the pipe furnishing the supply is attached, and a waste, R, to which the pipe for conducting away the waste is attac'hed.

(No model.)

Within the casing A is a main valve, G, provided with wings or guides a at its lower end, which guide and hold itin place in its motions through the guide-plate F and leather packing a, and a stem, H, provided with a water-way, M, and a flange near its upper end, on which rests the packing e, forming a valve which moves through the contracted part of the casing or chamber A, as shown.

To the upper end of the hollow stem H is screwed a short tubular stem, which securely holds the packing c in place, and forms a chamber for the valve k to play in, and large enough to leave afree water-way around it. To the outside of said stem is secured a flange, I, upon which rests a packing, d, and upon the top thereof is a packing, 6, working against N. Both of the packings I) and cl are held in place by the cap J screwed upon the upper end thereof.

The cap B is also provided with a small tubular opening, 9, leading from the chamber of the valve k to an annular groove, 8, and said groove 8 is opposite a corresponding groove, 8, in the upper end of the casing A, and between the casing A and cap B is placed an annular washer, h, for the purpose of securely packing the joint; and at intervals holes or slots t are out through said washer it, so that water passing from the channel 9 into 8 may find its way through the openings 11 into the annular channel 8, with which the vertical channel 9 is connected, and discharges into It. The object of the annular channels 8 s and holes 2' in washer his to afi'ord a passage for the water into g, no matter at what point the outer end of channel 9 may stop when the cap B is screwed upon A.

Near the base of the hollow stem N is a small orifice, 0, which opens a water-way from M through It into the chamber 1).

To the cap B is also attached a forming the fulcrum of the lever D.

To lever D 1s attached a weight, E, and connecting-wire 2, which, at its other end, is attached to a weighted lever, WV, which is both jointed and pivoted at Y, and said lever W is arrested in its motions around Y by stops to x, as shown. The lever D of Fig. 2 is shown depressed, and the lever W and wire z are shown dotted, the wire 2 being shown broken away post B from the depressed lever, and the end pointed in the direction indicating the position described and shown in Fig. 2.

The operation of my improved water-supply valve is as follows, to wit: Into any convenient part of the house, preferably at the spigot over the sink, is attached to the wall, the weighted lever W, from which, by means of the wire or wiresz, provided with bell-cranks in the usual manner, the weighted lever D of the stop-valve, placed in the cellar or under ground far enough to be secure against frost, is reached. The supply-pipe from the main is secured to the cap 0, the distribution-pipe to the outlet to, and a waste-pipe, connecting with a drain, to the waste It. \Vhen the lever W is turned into the position shown in dotted outline in Fig. 2 it causes the lever D to press the" valve k onto its seat, and thereby open the passage or water-way through L from M, and thence through 0 into the chainberp, and, by the pressure derived from the head of the supply produced therein, moves and holds the valves (1,6, and G in the position as shown in Fig. 2. \Vhen the lever W is turned into the position as shown in Fig. 1, it raises the lever D, which thereby relieves the pressure upon the valve 73, which is then caused to rise by the water-pressure, and a current of water is at once formed from M through 9, which, by means of its motion, carries the valve It: with it against its seat and holds it, thereby instantly closni g the passage through 7;, and so takes away the water-pressure in the chamber 1), and consequently relieving all downward pressure upon the valve G, which, being acted upon by the pressure from the main through T, is raised, as shown, opening the channels for the water-su 'i iily, indicated by the arrows to. \Vhen it is desired to shut oli' the supply from the house, the lever Wis turned into the position which then releases the weighted lever D, the weight E of which is made heavy enough to overcome the upward pressure of the water on It, which then depresses the stem L, diaphragm f, and valve k until it rests upon its seat in the cap B, thereby closing the channel g, and forcing the valve k to open against the pressure of the water, and thus form a current from M through 7c into N, and through 0 into the chamber 1), which, as is shown, is

considerably larger in end area than that of the valve G, and consequently when so arranged will press with greater force upon the area of the piston 01 and cap J than against the piston. G, and consequently cause it to descend until the piston G closes the inlets u and is arrested in its descent by the flange I, resting upon the shoulder formed in the easing A by the smaller bore thereof for the piston c, and the piston e passing below the lower end of its chamber or bore allows a free exit of the water around it from u through the waste It, as shown by the arrows r. The water entering the chamber 19, as shown by the arrow m, and receiving its pressure direct from the main, will hold all parts in the position as shown in Fig. 2, until the weight E is raised, as previously explained, when the valve is will at once close and raise the valve k which opens an outlet from the chamber 12 through 0 g s 'i s It, through which it is emptied as the pistons G, e, and d are caused to rise by the pressure of the water from the main against the piston G, which opens the water ways or inlets, as shown by the arrows it.

Having thus describ ed my invention, what I claim as new, and desire to secure by Letters Patent, is-
