FLUSH-TANK VALVE.

Application filed. March 3,

T 0 all whom it maywnoern:

Be it known that I, Cnron M. SAYLOR, a citizen of the United States, residing at Donor-a, in the county of IVashington and State 01 Pennsylvania, have invented certain new and useful Improvements in Flush- Tank Valves; and I do hereby declare the folloi-ving to be a full, clear, and exact description of the invention, such as willeuable others skilled in the art to which it appertains to make and use the same.

This invention relates to valves and more particularly to that class of valves which are used in connection with water closet tanks or the like where a float is employed to actuate the valve by means of a suitable lever connected thereto. a

In the ordinary type of inlet valve in use in flush tanks and the like, such type having a float with a lever attached, said float serving to automatically open and close the valve with the rise and fall of water in the tank, considerable disadvantages are to be found as well as numerous defects. In the operation of said inlet valve hissing sounds and knocks are to be heard upon the opening and closing of the valve and the issuing of water into the tank. Also the present devices in use are defective in that they are too complicated in construction and are liable to get out of order when submerged in water-as are the above type of valves. In. theusual type of inlet valve the valve proper remains seated under the tension ot'a spring and upon actuation by means of the float. Also the valve stem has its upper end bifurcated and a lever carrying a ball pivoted in said bifurcated end.

The object of my inventionis to provide an improvement in the above class of valves and to provide a. valve which is simple and compact in construction and eflicient and noiseless in its operation.

The invention will first be hereinafter more particularly described, with reference to the accompanying drawings which form a part of this specification and then pointed out in the claims at the end of the description.

In said drawings,

Fig. l is a plan view of the device;

Fig. 2 is a sectional elevation showing the valve in an unseated position as normally held by the spring before the water-has reached its height in the tank; .and

lookingin the direction of the arrows on the line v33 of Fig. 2.

Referring to said drawings, in which the same reference characters are used to desig nate corresponding parts in the different views, 1 denotes an inlet nipple or hollow valve base externally threaded and having anoutwardly extending flange 2 adjacent its upper end, the outer surface of which is polygonal in configuration and adapted for engagement by a wrench. From a point near the upper end of the nipple an internal annular enlargement 3 of its bore extends throughout a portion of its length, and serves as an accommodating chamber for a valve 23. Against the under side of the annular flange carried by the nipple is a leather washer 4 adapted for contact with the flange and cooperating with a fiber gasket 6 and nut 7 on the under side of the tank bottom ator attaching the nipple to the bottom of the tank. Screw threade'dly mounted upon the upper end of the nipple 1 is a valve body or casing 8 having an enlarged base and a reduced upwardly extending cylindrical por- 80. tion screw threaded at its upper end and having .a cap 10 screwed down upon the external screw threaded portion 9. A pivot bracket 11 extends outwardly and upwardly from the cap 10, which also has its surface polygonal, and pivotally supports a lever 12 at its bifurcated end 13 upon the thumbscrew .pivot 14:- The lever 12 has an internally screw threaded enlargement15 adapted for connection with a float (not shown). 0 Downwardly extending from the lever 12 is a hook 16. to which is pivotally attached a valve stem 17 by means of the eye 18 at its upper end, said valve stem passing through an aperture 19 in the cap 10 and through an aperture in the washer 20. The size of the eye is larger than the transverse section of the hook, thus providing for a limited independent movement between the lever 12 and the valve stem. Located in the valve body 8 is a cylinder 21 having at its lower end an inwardly extending annular flange 22 adapted to serve as a seat for the valve 23 carried on the valve stem 17 between adjustable nuts 24 and 25. The cylinder 21 is seated at its lower end on a packing ring of lead or the like material carried in a recess in the upper end of the nipple 1. The enlarged base of the valve body 8 has discharge openings 28 in the bottom and top thereof adapted to cooperate with discharge openings 29 in the side walls of the cylinder 21 to allow passage of the water into the tank. The valve stem 17 has its lower end reduced and screw threaded as at-30 upon which is adjustably mounted, by means of the nuts 24 and 25, the valve proper 23, the lower end of which is protected by a ferrule 31 of brass or like metal. Above the reduced screw threaded portion 30 is a second enlarged 'screw threaded portion 32 upon which is screwed a washer or nut 33 between which and the cap 10 is placed a coiled spring which tends to unseat and maintain the valve 23 in an unseated position.

The parts of my device may be constructed of brass with the exception of the gaskets 4, 6 and 20 which are of leather, fibre and composition packing respectively.

In operation when the tank 5 is empty the float will swing the long end of the lever 12 downwardly. Also the spring 34 acts to force the lever downwardly and at the same time carry the valve 23 a considerable distance away from the valve seat thus allowing the water to flow through the valve and the openings 29 and 28 in the cylinder 21 and the valve body 8 respectively, into the tank until the float is raised to a position causing the lever 12 by means of the hook 16 to exert a pull upon the valve stem against the tension of the spring 34 thereby causing the valve 23 to contact with its seat 22. As will be observed, in my device, the spring serves to counterbalance the pressure exerted upon the float and is adjustably secured against the cap by means of the nut 83. Thus I have produced a valve which acts etficiently, saves water and acts quietly, is simple in construction and will withstand hard wear.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent is 1. In a water inlet valve, the combination of a valve base, a valve body mounted upon said base, a valve seat mounted in said valve body and cont-acting said base, a cap mounted upon the valve body, packing means between the valve body and said cap, a valve stem, a lever pivotally supported by said cap and having a pivotal engagement with said valve stem, a valve located upon the opposite end of the valve stem, and adapted to contact said valve seat, a nut upon said valve stem and a spring between said nut and said cap adapted to maintain the valve in an unseated position when the pressure of the water is less than a predetermined amount.

2. A flush tank inlet valve comprising a hollow base member, a hollow body having secured. therein a tubular member mounted on said base member and provided with a valve seat, said body and tubular member therein,

having discharge openings therein, a valve stem extending through said tubular member into said base member and carrying a valve adjacent said seat, a fioat-lever fulcrumed on said body having a pivotal connection with said stem and adapted to close said valve. when raised by-the float, and a spring adapted to unseat said valve when the float-lever is lowered.

3. A valve for regulating the injection of water into tanks comprising a valve body having an enlarged. portion with apertures therein for the passage of water therethrough, a cylinder located in said valve body having an annular inwardly extending flange at one end adapted to seat upon a base and adapted to serve as a seat for a valve, a valve stem located in said cylinder and carrying a valve, a cap mounted on one end of the valve body and pivotally supporting a lever, a nut located on said valve stem, a coiled spring between said nut and said valve cap, a hook on said lever and connected to said valve stem and a float member mounted on said lever.

i. A tank inlet valve comprising a hollow base member, a tubular body mounted on said base member and enclosing a tubular part carrying a valve seat, said tubular part and said body having discharge openings a valve stem extending through said tubular part into said base member and having a valve thereon adjacent said seat, a spring acting on said stem to force said valve from its seat, and a lever adapted for connection at one end with a float and having a pivotal connection at its other end with said body and an intermediate connection with said valve stem. 7

5. A lever arm, for inlet valves, having an internally screw threaded enlargement at one end, the other end thereof being U- shaped and adapted for pivotal engagement with a valve cap by means of a thumb screw, and a downwardly extending hook adapted for engagement with a valve stem.

6. A flush tank valve comprising a tubular base member, a superposed tubular member having a-valve seat supported on said tubular member, said members having water passages therethrough, a valve stem suspended from a lever pivoted at one end on a fixed support above said superposed member and carrying a valve adjacent said seat, said lever carrying a float at its free end, and a spring acting in opposition to the upward movement of said float-lever to unseat the valve when the lever is lowered.

In testimony whereof I afiix my signature in the presence of two witnesses.
