MICHAEL BUCKLEY, OF MINNEAPOLIS, MINNESOTA, ASSIG-NOR OF ONE-HALF TO HENRY A. FRITZ, 0F MINNEAPOLIS, MINNESOTA.

CLOSET-TANK VALVE.

Specification of Letters Patent.

Patented Aug. 10, 1915.

Application filed June 10, 1912. SeriaINo. 702,707.

To all whom it may concern Be it known that I, MICHAEL BUGKLEY, citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Closet- Tank Valves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an extremely simple and highly efiicient closet tank valve; and to such ends, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claim.

Particularly, the invention relates to float controlled inlet valves, such as generally employed to control the inlet of water to closet tanks and other tanks having flushing valves for controlling the discharge, but the invention has nothing to do, specifically with the flushing valve.

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 shows a closet tank in vertical section and the improved float controlled inlet valve in elevation; Fig. 2 is an enlarged vertical section of the improved inlet valve, some parts being shown in elevation, and some parts being broken away; and Fig. 3 is a plan view of certain parts shown in Fig. 2.

The numeral 1 indicates the closet tank having an inlet pipe 2, shown as extended upward through the bottom of said tank and connected by an elbow 3 to the intermediate portion of an upright tubular valve casing 4. The valve casing 4 has an inlet nipple 5 that opens into a oentralchamber 6, located between similar upper and lower valve seats 7 and 8, respectively. Upper and lower valves 9 and 10 cooperate, respectively, with the valve seats 7 and 8, and when in closed positions, rest upon said seats. These two valves are, preferably, constructed of rubber, and they are seated against shoulders on, and accurately spaced, by a vertical valve stem 11. The lower end of this valve stem 11 is reduced in diameter, and works through a diametrically extended guide bar 12, located in the valve casing-4 below the lower valve seat 8. The upper end of the sald valve stem 11 is connected, preferably by a screw 13, to depending lugs of a piston or plug 14 that works with slight clearance in the upper end of the valve casing 4. The numeral 15 indicates a cap secured to the upper end of the piston 14 by a headed stud 16, and having a depending annular flange that is telescoped with slight clearance over the upper end of the said valve casing.

The valve casing 4 is preferably made in two parts or sections which are rigidly but detachably united at 4, by a screw-threaded joint located between the valve seats 7 and 8. The lower valve 10 should be of such size that it may be passed through the reduced upper end of the lower section of the valve casing 4. This facilitates assembling and repairing of the valve.

The numeral 17 indicates a lever which, at one end, is pivoted to a lug 18, shown as cast integral with the valve casing 4. This lever I 17 is intermediately connected to the plunger 14 and cap 15 by the headed stud 16, which latter is loosely passed therethrough. The other end of the lever 17 is connected by a short link 19 to the short arm of a lever 20, the long arm of which is provided with an ordinary or any suitable float 21. The lever 20 is pivoted to a lug 22, shown as east integral with the valve casing 4. As shown, the valve casing 4, at its lower end, is provided with a short discharge tube 23 that terminates near the bottom of the tank 1.

When the float 21 is raised by an accumulation of water in the tank, it simultaneously closes the valves 9 and 10 against their respective seats 7 and 8. When the valvesare thus closed, the pressure of water in the intermediate chamber 6 of the valve casing will be upward on the upper valve 9 and downward on the lower valve 10, and as the two valve seats 7 and 8 are of the same diameter, the force tending to move the valve stem 11 vertically will be neutralized. In this way, a balanced valve is provided. Slow leakage between the piston 14 and the valve casing 4, and between the said valve casing and the cap 15, prevents water from being caged under pressure in the valve casing. Also, the cap 15 prevents the water from spurting upward and directs the leakage downward.

The Valves, of course, open under the Weight of the float 21 when the water of the tank is lowered. The valve does not close with a sudden movement and is noiseless in its action.

cap equipped piston, working in the valve casing outward of the other of said valve seats, with its cap telescoped ontosaid valve casing, said valve stem being flexibly connected to said cap equipped piston, and a float actuated lever connected to said cap equipped piston, substantially as described. In testimony whereof I aflix my signature in presence of two Witnesses.
