VALVE.

Specification of Letters Patent.

Patented June 29, 1909.

Application filed June 14, 1907. Serial No. 379,009.

To all whom it may concern:

Be it known that I, PATRICK J. FREANEY, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Valves, of which the following is a specification.

The object of my present invention is to produce a valve for controlling the inlets of flushing tanks in which a large proportion of the usual mechanism shall be dispensed with. Said invention will first be fully described, and the novel features then pointed out in the claims.

Referring to the accompanying drawings, which are made a part hereof, and on which similar reference characters indicate similar parts, Figure 1 is a front elevation of a tank of the character in question, a portion of the front wall at one end being broken away to show the location and arrangement of my improved valve therein Fig. 2, a central vertical sectional view, on an enlarged scale, of the valve separately, the parts being in the position they occupy when the valve is closed, and Fig. 3, a similar view with the parts in the position they occupy when the valve is open.

The tank 21 is any ordinary flushing tank, having an ingress pipe 22 and an egress pipe 23. The egress pipe may, so far as my invention is concerned, be arranged and controlled in any desired manner, as my invention relates wholly to the control of the How of the fluid which enters the tank through The main part or shell 31 of this valve I prefer to secure to the floor of the tank, as by means of nut 32. The fluid enters the chamber 33 of this valve in the usual manner. Centrally arranged within the valve structure is a valve seat 34, and leading out from below this valve seat, through the side or wall of the valve structure, is a discharge orifice 35, smaller in diameter than the ingress orifice leading into the chamber. Above this valve seat, within the chamber, and adapted to have a free but limited movement therein, is a valve 36 which is adapted (when the valve is closed) to rest upon the valve seat. I prefer to make that portion 37 which directly contacts with said valve seat, of rubber, leather or some other comparatively soft or yielding material. The upper portion of this valve is of substantially the same diameter as the interior of the chamber within which it is seated, but lits somewhat loosely therein, so that it is free to move toward and from the valve seat within the limits permitted by the construction. This looseness of lit also forms a by-pass and permits a small amount of fluid to pass up by it to that portion of the valve-chamber above the valve.

Secured upon the upper end of the main valve structure 31 is a cap 41 which forms the top wall or the upper end of the chamber. A comparatively small orifice 42 leads up through this cap, and at the bottom of said orifice a valve seat 4-3 is provided. Above said cap a small lateral opening or openings stat permit any lluid which may enter the portion of the chamber of the valve structure above the main valve to freely discharge so long as the small valve, closing the orifice through the cap M, is open. A valve 45 is provided to close the orifice 42, and this has a long stem d6 which extends up through the top of the valve structure, and the upper end of which is supported by a stay-bar I? near the top of the tank. On said valve stem are collars l8 and 4-9.

Surrounding the valve stem 41:6 is a float 51 This float may be of'any desired form or construction. I have shown it as of a plain cylindrical form, with an open-ended tube 52 extending between its two heads to form a way for the valve stem 16.

The operation may be described as follows: The fluid enters in the usual way through the pipe 22. Reaching the valve chamber, when the valve is open, it passes up, over the valve seat 34, and out, through the discharge orilice 35, into the tank. As the tank fills, the fluid reaches and raises the float 51. When this float strikes the collar 49 on the valve rod 46, it raises the valve 45 against the valve. seat 43, thus stopping the escape of the small amount of fluid which has so far been passing out through the orifices 42 and a l, and which has been supplied by reason of the looseness ol' the main valve 36 acting as a by-pass as above described. As soon as this small dis charge is stopped, the pressure in the chamber around the main valve 36 becomes equalized, and the weight of said main valve causes it to thereupon promptly descend and become closed and, after it reaches its seat, the water pressure upon the upper side thereof causes said main valve to remain tightly closed until the pressure on the upper side is reduced by the re-opening of the small valve 45. When the tank is discharged by opening the valve (not shown) which controls the egress pipe 23, the float 51 will descend until it strikes the collar 48 on the valve stem 46, which has the effect to open the valve 45, permitting the discharge of fluid through the orifices 42 and 4% to be resumed. As soon as the pressure above the main valve 36 is thus relieved, said main valve will be instantly opened by reason of the pressure thereon from the fluid in the pipe 22, and the tank will be refilled in the manner which has already been described.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is

1. A flushing tank valve comprising a main body having an inlet, an outlet, an intermediate valve chamber and a valve arranged therein to close the outlet by accumulated pressure o'l' leakage from the inlet past the valve, a valve controlling an outlet from the end of the valve chamber opposite the inlet and normally held closed by the pressure of water in the chamber, and a float connected to said valve and having a free movement relative to said valve and independent thereol whereby said last men tioned valve Will be opened by the float only at the lower end of its free movement and closed only at the upper end of its free movement.

2. A flushingtank valve comprising a main body having an inlet, an outlet, and an intermediate valve chamber, of a valve mounted in the valve chamber and adapted to rest by gravity upon its seat with a leakage past said valve to that portion of the valve chamberbeyond the inlet, said portion of the valve chamber having an outlet, a valve for closing said last mentioned outlet arranged Within the outer end of the valve chamber and subjected to the pressures therein whereby it is normally held closed by such pressures, said valve being normally urged away from its seat, a stem connected to said lastmentioned valve and having a pair of separated collars, and a float mounted on said stem between said collars to have a considerable play therebetween and to engage the same to shift the last mentioned valve toward and from its seat.

3. A flushing tank valve comprising a main body having an inlet, an outlet, and an intermediate valve chamber, of a valve mounted in the valve chamber and adapted to rest by gravity upon its seat with a leakage past the said valve to that portion of the valve chamber beyond the inlet, said portion of the valve chamber having an outlet, a valve for closing said last mentioned outlet arranged Within the outer end of the valve chamber and subj ected to the pressures therein and normally held closed by such pressures, said valve being normally urged away from its seat by gravity, a stem connected to said last mentioned valve and having a pairol' separated collars, and a float mounted on said stem between said collars to have a considerable play therebetween and to engage the same to shift the last mentioned valve to- Ward and from its seat.

In witness whereof, I, have hereunto set my hand and seal at Indianapolis, lndiana, this twenty-second day of May, A. D. one thousand nine hundred and seven.
