QLOW-CLOSING TANK VALVE.
SPECIFICATION forming part of Letters Patent No. 391,659, dated October 23, 1888.
Application filed May 5, 1888. Serial No. 272,970. (No model.)
Closing Tank-Valves, of which the following is a specification.
The nature of my invention consists in the improved construction of the valve, whereby the same, after being raised, is allowed to fall gradually to its seat, thus causing the water to run under the valve for a suiliicient length of time to properly flush the seat of a watercloset.
Figure 1 is a side elevation and partial section of my improved valve. Fig. 2 isa detail view showing a plan of the supporting-bar for the valve-rod.
In the accompanying drawings, A is the overflow-pipe; B, the pipe leading from the tank to the water-closet.
O is the valve-seat, which is to be located at the lower portion of the water'tank. The valve-rod D is securedloosely in an upright position from the supporting-bar E, and is provided with a central perforation, a, extending downward from the upper end to connect with the side perforations, b 1), adapted for the entrance of water upon the upward movement of the valve F, a suitable check-valve, a, being provided at the upper end of the hollow valve-rod D to prevent the return of the water through the perforations I) b upon the return downward movement of the valve F,
the valve 0 being suitably held in operative connection with its seat by means of the perforated cap or plate d, or otherwise. The valve-rod D is made cylindrical in its external surface and loosely fits the bore of the valve-tube G, which is closed at its upper end, and is provided with the lifting-chain H, by means of which the valve is to be operated as required. G is provided with an inverted-dish-formed tlange,g,witl1in which is secured a ring of lead, j, which serves to impart sufficient weight to the valve. The face of the valve is provided with a leather washer, I, which is secured to the valve by means of the not 0.
Upon the overflow-pipeA is placed the adjustable stop J, which serves to adjust the limit of the upward movement of the valve, in
The lower end of the valve-tube order to provide for a desired change in the amount of water employed to flush the closet,-
pulling upon the lilting-chain H, will cause the surrounding water to flow into the openings b b and into the chamberK bylifting the valve 0 from its seat f through the suction so produced, thus filling the chamber K above the valve 0 with a certain amount of water, which amount will be controlled by the position of the stop J, the projecting end of which acts upon the upper side of the flange g, and upon the release of the valve F the water in the chamber K will, by the closing of the valve 0, be caused to pass downward between the cylindrical periphery of the valve-rod D and the bore of the valve-tube G, andjn this case the escape of the water can be made as slow as desired by properly fitting the said valve rod and tube to each other to leave the proper amount of space between them.
The valve-rod D is made loose in the perforation h in the bar E, in order that the valve F may become in all cases properly closed upon its seat 0 without cramping upon. the valve rod, and by this means the cost of manufacture is materially lessened,and the accidental disarrangement of the valve by injury to the valve-rod by bending is avoided.
I claim as my invention The combination, with the pipe 18 and valveseat 0, of the bridge E, hollow valve-rod D, held loosely in a perforation in the bridge to have a swinging movement therein and provided with the inlet-passages b and longitudinal perforation a, the valve a, perforated cap or plate d, the valve F, provided with the suction-tube G, which loosely fits the loose rod D, and means for raising the valveFfrom its seat 0, substantially as described.
