PATRICK VINCENT DIVYER, OF UT. IAIII., MINNESOTA.
WATER-CLOSET FLUSH-TANK VALVE.
SPECIFICATION forming part of Letters Patent No. 394,475, dated December 11, 1888.
'Application filed September 28, 1888. Serial No. 288,636. (No model.)
To @ZZ whom it may concern:
Be it known that I, PATRICK VINCENT DWYER, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in \Vater-Closet Flush-Tank Valves, of which the following-is a specification.
This invention relates to flushing-tanks of water-closets; and it consists in the construction, combination, and arrangement of parts, as hereinafter shown and described, and specifically' pointed out in the claim.
In the drawings, Figure l is a sectional side elevation of a portion ofa tank and valve with the valve closed. Fig. 2 is a cross-sectional view of the valve and its casing, the valve being in section through its ports on the line X X of Fig. I and the casing being in section through the casing on the line Y Y of Fig. l. Fig. 3 is a view similar to Fig. l with the valve open.
A is the tank, having a combined valvecasing and overtiow, B, opening down th rough its bottom, and either cast in one piece with the tank, as in Fig. l, or secured therein by the usual coupling, as in Fig. 3, or in any other suitable manner, although I prefer it cast in one piece with the tank, as in Fig. l, when a cast-iron tankis employed. This casing B is open at the top and provided with ports a, generally at or near the bottom line of the tank A, and with a valve-seat, b, below the line of the ports a.
The valve consists of a tube, D', having a closed top, D2, and open at its lower end, and with ports e near its upper end, and provided with a ring, E, of rubber or other suitable flexible material, at or near its bottom end, and a similar ring, E2, at or near its upper end above the ports e, the function of the rings being to form packings between the valve and its casing and prevent the passage of the water.
Vhen the valve is closed, as in Fig. l, the lower ring, E', will be below the ports a and the ring E2 will always be above the ports e, so that the water in the tank will not flow out through the discharge, but will rise to the height of the ports e, as indicated by the dotted line X X in Fig. 1. The valve and` its casing, when the former is closed, thus form a sealed overiiow or trap to the water in the tank. 'hen the valve is elevated, however, by pulling down the chain or cord F attached to the operating-lever F2, the ring E is raised above the ports (L, as shown in Fig. 2, when the water is free to flow directly into the discharge, and will continue to flow as long as the valve is held open.
The act of raising the valve will increase the air-space and form a partial vacuum in the valve and in the casing surrounding it, and the flow of the water will also draw ott' some of the air already in the valve and casing, and thereby increase the vacuum, so that when the valve is released and returns to its seat the pressure ot' the air on the water in the tank will cause the water to rise in the casing and overtiow into the valve and escape by the discharge, the two tubes B I) being thus transformed into a siphon, the water thereby continuing to 'tl ow from the tank until it falls to the level of the ports (l, when the vacuum will be destroyed by the inrushing air and the water cease to vflow from the tank. The water flowing into the tank by the ordinary feed-pipe will then rise in the tank to the level of the ports e, the valve D and casing B thereafter serving as a combined overflow and trap.
The position ot' the ports u e may be altered to any desired extent, the raising' or lowering of the ports causing the amount of water flowing froln the tank to be increased or decreased correspondingly.
I claim several important advantages by this form of construction.
The whole device is extremely simple and inexpensive, and will not, therefore, bc easily disarranged or become inoperative. The parts are few in number and will not require nice adjustments to cause them to operate.
The parts of the valve in contact with the casing are ot rubber, so that its operation will be noiseless and the parts will not require tine finishing to secure perfect action, as the lieXible packing-rings will adapt themselves to the inequalities of the surfaces.
Another important advantage is found in the fact that by this construction the valve cannot become unseated when being operated,
IOO
as the throw of the lever F2 can be so easily controlled as to prevent the valve being lifted high enough to remove it from the casing B.
Another important advantage is gained by fastening the valve-casing rigidly to the tank and connecting the operating-lever directly to the casing, thereby not only securing a more rigid connection, but preventing any disarrangement by reason of the unequal movements of the parts.
When a cast-iron tank is used,I will generally cast the casing B in one piece with it, as shown in Fig. l, which will greatly simplify the construction and reduce the expense.
The operating-lever F2 is capable of being turned in any direction by merely loosening the casing B in the tank When it is fastened thereto, or attaching the lever-standard to some other point on the casing when the lat- 25 ter is cast in one piece with the tank. l
Having thus described my invention, whatI claim as-newis- In a water-closet flush-tank valve, a casing, B, secured ina fixed position in the tank and 3o discharging downwardly through the bottom thereof, and provided with ports a and valveseat b, a valve, D,within said casing, open at the bottom and closed at the top, and having ports e and packing-rings E E2, and means 35 whereby said valve may be elevated and low- 4 ered, substantially as and for the purpose set forth.v
In testimony whereof I have hereunto set my hand in the presence of two subscribing 4o Witnesses.
PATRICK VINCENT DWYER.
