FRED WILLIAM MEYER, OF LOUISVILLE, KENTUCKY.
FLUSHlNG-VALVE.
SPECIFICATION forming part of Letters Patent No. 661,885, dated November 13, 1900.
' Application filed April 9, 1900. s mi n 12,153. on model-J To all whmn it may concern.-
Be it known that I, FRED WILLIAM MEYER, of Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvementsin Flushing-Valves; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.
This invention is an improvementin flushing-valves especially adapted for use as automatic flushing-valves for waterclosets, for stop and waste valves for systems of water distribution in buildings, and for various other purposes in the arts where such valves can be usefully employed.
The invention consists in the novel construction of the valve shown in the drawings and hereinafter described with reference thereto.
In said drawings, Figure 1 is a side elevation of the valve applied to the bowl of a water-closet. Fig. 2 is an enlarged longitudinal sectional view through the valve. Fig. 3 is a view of the valve applied to another water-closet fixture. Fig. 4 is a view of the valve applied to other fixtures. Fig. 5 is a detail.
The valve-casing O is approximately U- shaped, being provided with an inlet-chamber A in its upper leg and anoutlet-chamber B in its lower leg, the latter being connected with the former by a bend, and at the bend intermediate chambersA and B is a storagechamber D. Within chamber A is a valveseat a, and at the junction of the chambers B and D is an oppositely-facing valve-seat b. The outlet-chamber B has a discharge-opening e, which communicates with a suitable flushing-pipe E, and the inlet-chamber A has an inlet-openingf, which communicates with a suitable water-supply pipe F. Within the chamber A is a valve a, which is adapted to close against the seat a, and within the chamber D is a valve 1), which is adapted to close against the seat I). The valves a b are substantially parallel, but face in opposite directions, and are rigidly connected, so that as one is opened the other is closed. As shown, the valve b is mounted on the inner end of a rod G, which extends through a stuffing-box B'iu the outer end of chamber B and ing g, which extends through the chamber- D, and the valve a is secured to the upper end of casting g by means of a screw g, as
shown, the casting g thus lying transversely of both valves. Thus the parts G, g, and g practically form the valve-stem and are rigidly connected, so that they move as one. The stem is thus made in sections for convenience in assembling the parts within the valve-casing, and the outer end of chamber A is closed by a screw-cap A to enable the parts a g to be readily secured in place. A spring H is interposed between a nut h on red G and the outer end wall of chamber B, this spring serving to normally force the stem inward, so as to normally hold valve 1) open and valve a closed. In some cases a weighted lever T may be employed to operate the valvestem, as indicated .in Figs. 2, 3, and 4.. The storage-chamber D may be connected by a pipe I to a tank "L in the usual manner, and the flushing-pipe E may be connected directly to the bowl J of the closet, if desired, as shown in Figs. 1 and 3, Fig. 1 showing the most direct and preferable connection of the valve to the closet and tank, or the flushing'pipe E may lead to the soil-pipe S, as in Fig. 4.
The closet shown in Fig. 1 has a hinged seatj, which may be provided with any suitable upholding-springs, (not shown,) but such as are well known. This seat is hinged to the bowl, and to the hinge of the seat may also be hinged a short bifurcated lever K. It is preferably so hinged to the seat that the latter can be raised to permit inspection or cleansing of the bowl; but when the seat is lowered beyond the point allowed by its spring the lever K will be rocked forwardly and its upper bifurcated end will engage the collar or head on the outer end of rod G and pull the valve-stein outward whenever the seat is pressed downward. Thereupon valve 1) will be seated and valve ct unseated, and immediately water will flow from chamber A through the storage-chamber D into pipe I and up into the tank, and the pressure of the water will now partially assist in holding the valve 1) closed. When the pressure on the and in so doing will seat valve t.
seat is relieved, the spring H and the pressure of water on valve a" will unseat valve 1) Thereby the supply of water from pipe F is cut off, and the water collected in the storing-chamber D, pipe I, and tank t'is permitted to flow back through chambers D and B into the flushing-pipe E and thence into the bowl, flushing the latter, as is obvious.
Owing to the opposite arrangement of and connection between the valves ct b they are balanced-that is, whenboth are opened the tendency of the water-pressure to close one valve is countervailed by the tendency to close the other valve. This facilitates the operation of the valve; but as soon as one valve is seated the whole pressure is exerted thereon and keeps such valve closed by reason of the exhaust on the opposite side of the closed valve.
Fig, 2 shows inlet-valve a closed, and natu rally the pressure of water in theinlet-cham her A will assist in keeping this valve closed, while at the same time the water that has accumulated in the storage-chamber escapes freely past the open valve b, while when the seat is depressed and the rod G drawn outward, so as to close valve 1), of course valve 0/ is simultaneously opened, and the pressure of the water then in the chambers A and D will be practically neutralized on the valve ct and be exerted wholly on the valve 19' and assist in keeping the latter closed, and as soon as the storage-chamber is full the pressure of the entire head of water will then be exerted to keep valve 1) closed. This is'one of.the objects of the construction of my valve and renders the operation thereof very easy, for it is only necessary in order to flush the closet that sufficient pressure be exerted on the rod G to overcome the pressure of the water against valve 1). As soon as this pressureis overcome and the valve 1) opened the the latter valve, as before.
rushof water past valve 0, will tend to close Thus practically in myconstruction the head of water is utilized in seating or in holding seated both valves (1 and b, which is a practical advantage where the device is used in connection with water-closets, as owing to the consequent ease of operation of the valve trembling and jarring of the seat are prevented.
Preferably the chamber B may be provided with a drip-outlet b, that can be connected by a pipe L, Figs. 3 and 4, with the soil-pipe S or other outlet ata point sufiiciently below the chamber B to insure the proper drainage of all water therefrom when the valve (1 is closed. Thus freezing up of the valve is prevented by draining all water therefrom.
Fig. 3 shows the valve arrangedbelow the closet-floor, and in this case the collared end 0 of stem G is engaged by the short'arm of an angle-lever T, pivoted on the casing and having a weighted outer end by which the stem will be normally forced inward, so as to close valve (1. and open valve 1). This lever T may be connected to the closet-seat, as indicated in Fig. 3, by a chain or cord, so that when the seat is depressed the valve b will be closed and valve a opened.
In Fig. 4 the valve is shown connected with the piping-0f a house, to be used as a stop and waste valve.
What I claim as new is 1. In a valve, the combination of the inlet and outlet chambers, and the'intermediate storing-chamber communicating therewith, the oppositely-facing valves for closing communication respectively between the inlet and storing chambers, and between the storing and flushing chambers, the stem or casting working in the storing-chamber and subject at all times and upon all sides to the pressure in said chamber and connecting said valves whereby when one valve is opened the other is closed, and the valve-rod for displacing the valves, each of said valves being adapted to be held closed after being seated by the pressure of the water in the casing, substantially as and for the purpose described. v
2. -In a valve, the combination of the inlet and outlet chambers arranged side by side, the storage-chain ber communicating with the inner ends of both the inlet and outlet chambers, the oppositely-facing balanced valves 'for closing communication between the storage-chamber and the inlet and outlet chambers respectively, the rigid transversely-disposed connection between the valves within the storage-chamber and unaffected by the pressure of water therein, the valve-rod extending through the outlet-chamber and connected to the outlet-valve, a spring on said rod within the outlet-chamber for unseating the outlet-valve, and exterior means for operating said rod; with the supply-pipe communicating with the inlet-chamber, a flushing-pipe communicating with the outletchamber, and the tank communicating with the storage-chamber, all so arranged that the pressure of the water on the valves when both are opened is balanced, but will hold either valve to its seat after it is closed, for the purpose and substantially as described.
3. In a flushing-"alve, the combination of a U-shaped casing provided with an inletchamber in one leg communicating witha water-supply, an outlet-chamber in its other leg communicating with a flushing or waste pipe, and a storage-chamber communicating with both the inlet and outlet chambers; with the oppositely-facing balanced valves for closing communication between the storage-chamber and inlet and outlet chambers respec- :tively, the casting in the storage-chamber and subject at all times and upon all sides to the pressure in said chamber detachably connected to the face of one valve and to the back of the other and the valve-rod extending through the outlet-chamber and through the outlet-valve attached to said casting, and connections whereby said stem is operated IIO so as to close the outlet and open the inlet valve, substantially as described and for the purpose set forth.
L. The combination of a U-shaped casing having an inlet-chamber in one leg and an outlet-chamber in its opposite leg and a storage-chamber communicating with both legs at the bend of the casing, the oppositely-facing valves for closing communication between the storage-chamber and the inlet and outlet chambers respectively, a detachable connection between said valves within the storage-chamber and subject at all ti mes and upon all sides to the pressure in said chamber, the rod extending through the outletchamber but rigidly attached to said detachable connection aud a spring on said rod for opening the outlet-valve and closing the inlet-valve, and means for forcibly opening the inlet-valve and simultaneously closing the outlet-valve, each valve being held closed, after being seated, by the water-pressure, for the purpose and substantially as described.
5. In a water-closet valve, the combination of the water-closet bowl, the tank, and the flushing-valve interposed between the bowl and tank having a U -shaped casing provided with an inlet-chamber in one leg communicating with a Water-supply, an outlet-champressure in said chamber detachably connected to the face of one valve and to the back of the other and the valve-rod extending through the outlet-chamber and through the valve between the outlet and storage chambers and attached to said casting and connections whereby said stem is operated from the closet-seat to open the inlet and close the outlet valve, and a spring for opening the outlet-valve and closing the inletvalve, all substantially as and for the purpose described.
In testimony that- I claim the foregoing as my own I affix my signature in presence of two witnesses.
