To all whoml z'tmdy concern.' p
Be it known that I, Winrnan J. ROULEAU, a citizen of the United States, and resident of Quincy, county of Norfolk, State of/Massa.- chusetts, have invented an Improvement 1n Flush Valves, of which the followingde` scription, in connectionl with the accompanying drawing, is a specification, like characters on the drawing representing like parts.
This invention relates to flush valves, and it has for its object to provide a novel flush- .ing valve which is constructed to eperform the desired flushing operation without the use of the ordinary ilush tank. Myl iml proved valve is s'o arranged that when it is.
actuated, it will permit the water to flow freely through the discharge pipe for a. predetermined length` ofy time land will then automatically close.l I
In order to give an understanding of my invention, I have illustrated ini the drawing. a selected embodiment thereof, which will now be described, after which the novel feav tures will be pointed out in the appended Y claim.
In the drawings, Fig. 1 is a top plan view of a flush valve embodying my invention.
Fig.- 2 is a vertical sectional view on the line 2-5-2, Fig. 1.
My improved flush valve comprises a valve casing 1, provided with an inletlpo-rt 2, which is connectedI to the water supply system and also provided with a discharge port 3, which communicates with the discharge pipe 4,`that leads to the bowl or other container to be flushed. The valve casing is also provided with situated between the inlet and the outlet, and which is normally' closed by avalve 6 which seats thereon. This valve 6fis formed with a valve stem 7, to which is connected a exible diaphragm 8, the llatte forming one side of a valve chamber 9, in which the The valve casing is also provided with a chamber 12 situated above the dia- 'pressure' andthe latter hasl'a bleedfhole 13 phragm,
therethrough, so that under normal condi-` tions water will accumulate in the pressurechamber 12, so that there will be the same pressure in said chamber 12 as in the valve chamber 9. Under these conditions, the
a portedvalve seatl 5 valve 6 will be normally held to its seat by the pressure of the water thereaganst. The valve 6 is opened by relieving the pressure 1n the pressure chamber 12,` and when this is done, the water pressure against the under side of the diaphragm 8 will over-balance the pressure against the valve 6 because g the diaphragm is of a considerably larger area than the valve, and as a result the valve 1 valve casing with a duct 14, communicating with the pressure chamber atene end' and with the discharge pipe 3 at the other end, and I have provided a manuallycontrolled valve 15 by which said duct 1s closed or opened. When the valve 15 is closed, the water will leak through the bleed hole 13 -until the pressure on both sides lof the diaphragm is equalized, at which time the valve 6 will close. When the valve` 15 is opened, the pressure in the pressure chamber 12 is relieved, and the valve 6 will open automatically. i
This valve 15 seats against a valve seat 16,v
-\wi-ll be lifted from its seat, thereby allowing surrounding a port 17, and it is carried by a valveI stem 18, which, is slidably mounted in a `iittm'g v19. This fitting has an interior rib 20, which fits the valve stem 18, and the latter is provided at its outer end withtheY head having a portion 21 of 'smaller diameter f that slidingly fits the fitting 19, and aportion- 22 of larger diameter. which slidingly` tits the interior of a cap member 23, which 1s screwed to the tting-19. A spring 24 surrounding the valve stem and bearing at one end against the rib 20 and at the other against the portion 21, serves to yieldingly hold the valve 15 against its seat 16. The valve is opened by means of an operating handle 25, which extends into the member 23, and is valve stem 18 has the axial bore 27, in which is slidably mounted a pin 28, the latterbeing backed by a spring 29. Thea-handle 25 canbe swung or tilted in any direction2 and when it is vso ti'lted it will act on the pm 28 formed with thehead 26. The( to move the valve stem 18 to the right, thereby opening the valve 15. As soon as the valve is opened, the pressure in the chamber 12 is relieved, and the excess pressure on.the
under side'of the diahragm 8 will o erate mains o en will depend upon the size of the bleed ho e 13. I
`In the construction shown, the valve seat -16 is formed with the shoulder 3l and a gasket 32 cooperates with said shoulder to make a tight joint. Said valve seat is held in place by the fitting 19 which is screwed into the boss 30 formed on the valve easing. Said fitting is also provided with lateral openings 33 for the passage of Water.
The valve 6 is held infits right line position by means of two guiding 'ins 34 and 35, which are secured thereto, an one of which operates in a guide 36, carried by the bridge V 37, and the other of which operates in a guide 38, carried by the cap 39, which is screwed into the top of the valve casing.
The valve stem,18 cari-les a bafi'ie disk 40 which rests against a shoulder 41 formed on said stem and is retained in place by a sleeve 42. The purpose of this baille disk is to defleet downwardly the water passing through the valve seat andthereby prevent the water from leaking past the valve stem.
The function of the spring-pressed pin 28 head26, and the pin 28 will function to hold ithe handle 25 normally in horizontal posiion.
