To all whom it may concern: Be it known that I, THOMAS F. PAYNE, of Pittsbur 1n the countyof'Allegheny and State of ennsylvania, have invented a cer-' tain new and. useful Improvement 1n Flushing-Valveaof which the following is a full, clear, and. ezia'et description, reference being had to theaccompanying drawings, forming part of this specification, in which- Figure 1 is a rear elevation of a valve illustrating my invention; Fig. 2 is a side elevation, partly in section Fig. 8 is a vertical section showing the valve in its lowered position; Fig. 4% is a vertical section showing the valve in its raised pos1tion;'F1g. 51s a' is a section on the line 1313 of Fig. 9; and

14 is aseetion on the line14-14 of Fig. 12.

Heretofore influshing valves for'water- "closets of that class in which the bowl is flushed by the direct iiow of water" from the main, and is controlled by the filling of the valve chamber, the aperture-which permits the flow of water to the upper face of the valve, to create a closing pressure, is minute and, apt to be clogged by foreign matter which may besuspended in the water, Whereby the operation of the valve is often interrupted requirin the valve to be taken apart and cleaned. nether diiliculty has been found in-closing the valve where pressure in the waterinain is insufficient or becomes low, which allows the water to pass through the I valve without power to close the same. An-

Eli

other difliculty has been found in the neces sity of taking the valve apart in order to adjust it to the amount of'water to be deliveredto the bowl, or the length of time it is desired the valve shall remain open.

" The object of my invention is to obviate these objectionable features, and it consists in a valve having devices for causing a reverse flow of water through the filling a erture whereby the same is continually was ed out and kept clean, in devices for creating a partial vacuum in] rear of the operating. iston, and in devices for ad ust1ng'the va Specification of Letters Patent.

and it also consists in devices and features of construction heremafter more fully set forth.

others skilled in the art may employ the same.

In the drawing, 2 represents the threaded socket or inlet adaptedto communicate with 5 the water main, and 3 and 3 represent the 6,5.

valve chamber, the upper portion 3 of which is of greater area in cross section thanflthe' I lower-portion 3*. At the lower portionof 1 5 the valve chamber 3* isthe valve-seat, 4. 'Sit uate in the valve chamber is a piston valve: having an upper piston head 5 located in the upper portion 3 of the valve chamber and a lower piston head 6 and a valve 7 located, in the lower portion 3* of the valve chamber.

The piston heads 5' and 6 are provided with 5 washers or packing 5 and 6* which fit.

tightly against the walls of that portion of the valve chamber in which they are respec tively located. I The valve 7 is providedwith a washer 7 adapted to close the water-way 30 ofthe valve-seat 4. The piston-heads 5 and i 6 and the valve 7 are mounted on the stern 8.

The valve chamber 3* communicates by the passages 9 with the pipe 10 that leads to the bowl. This pipe 10 is shut off by the parti 7 tion 11- from direct communication with the inlet 2'. Leading from the inlet 2 is an inlet by-pass 12, which at its other endcornmnnifl cates with the port 13 of the plug 14; of the cook 15, the passage of communication be .tween the passage 12 and the port 13' being." minute, although the passage 1 and thepoit 13 are ofmuch larger area. In the bushih m'unica-tee with the outlet by-pass18 thatt leads to the passage 9. The plug 14 is v-ided with a central cavity 19 that coin nui sageh2O which leads to and opens into-the op- 7 per portion of the valve-chamber 3 abovethe piston head 5. Theplug 14: is provided with a lever arm 21 having a slot in which isle 24 which is supported by the spring 25 lathe casing'26. At the top of the casing 26 isa 1 I will now describe my invention so that 6 the tinfe oiii 1.9.

eterthan the valve casing, which plug serves to choke the flow ofwater before the valve closes and yet permits the bowl to refill at the close of the flushing action.

In Figs. 7 and 8 I show a modification in which the push button 24 is arranged horizontally, connected with the lever 21?, and is adapted to extend through va wall.

In Figs. 9,'10, 11, 12, 13, and 14 I show a modification in which the plug 14" and the push button 24 are placed on top of the valve casing instead or at the side thereof. In this modification the connection with the water main pipe is at 2 and the pipe leading to the bowl is at 10 The piston valve hav- 'ing the heads 5 and 6? and the valve '7 b are of dilferent shape and the location of the parts is different from that shown in the other figures. In this modification the cavity 19 and port communicate directly with the valve chamber 3*.

t In .my improved valve or metric flush the parts are normally in the position shown in Figs. 1, 2, and 3, there being a minute opening between the passages .12 and 13 which allows water to flow from the inlet 2 through the passage 20 to therupper portion 3 of the valve chamber where itexerts downward pressure against the piston head 5, which is of greater area than the lower face of the valve 7 against which the water from the inlet 2 exerts an upward pressure. This downward pressure therefore normally keeps the valve 7 closed against its seat 4 and prevents water from flowing to the bowl. Then the push button 24 is. pressed downwardly against the force of the spring 20, the lever 21 gives apartial rotation to the plug 14 I which carries the port 13 from the inlet pas sage 12' to and into communication with the outlet port 17 and passage 18.- This shuts off the water communication between the inlet 2 I and the chamber 3 and opens a free passage to the bowl, thus flushing thecloset.

between the chamber? and the passage 18 against which is merely atmospheric pres-. sure. The pressure of'the water below the valve 7 thereupon becomes greater than the pressure on the piston head 5 and the valve 7 is forced upwardin the chamber 3 causing the water in the chamber 3 to be forced out through the passag'es'20, 19, 17 and 18, and permits the water from the inlet 2 to flow in volume through the passages 9 and pipe 10 packing of the piston head .6 fitting closely in the chamber. 3 serves to'keep the pressure of the water in the-main from being exerted against the lower side of the piston head 5.

WV'hen it is desired to stop the flow of.

water through the'pipe 10, the push button 24 is released and the spring 25 carries it and the lever 21 back to their normal positions and turns the plug 14,.bringingthe port 13 out of communication with the passage 18 and again in such partial register The inlet and in another with the passage 12 as to forma minute opening between the passage 12. and the port '13, which again permits the water from the. inlet 2 to flow through the passages 12,

. 13,19, and 20'into the chamber 3, and there to gradually close the valve 7 under the greater pressure above' the piston head 5 than exists below the piston head 6. During this slow closing movement the water continues to flow in volume to the pip'elO until the plug 27 enters the contracted .portion of the valve casing below the valve seat and chokes the flow of water, permit-v ting only sufiicient water to passthe valve as is necessaryto refill the bowl. As the cross area of the chamber 3 is greaterthan the cross area 01"" the chamber 3 the upwa'rd movement of the piston heads 5 and 6 creates a partial vacuum behind. the piston head 5 which aids in the return movement of the same.

The advantages of my invention result from the construction which causes the out? flow of water from the valve chamber to pass through the inlet port in a reverse direction keeping this passage at all times clean and free from obstructions that would interfere. with the operation of the valve; also from the devices which enable a small pressure of water to closethe valve; and from devices outside of the valve and by means of which the time occupied in the closing of the valve may be regulated.

Many modifications in addition to those shown in the drawings may bemade'in the. form and location of the parts without departing from my invention.

Alt ough I have shown my invention applied o a valve for flushing water-closets, I do not desire to-limit it to this use.

- Having thus described my invention, what I claim' and desire 'to secure by Letters Patent is 1. Ina flushing valve, the'combinationof a valve chamber havinganimperforate side therein, a passage leading to the valve chamber, an inlet, an outlet, and a plug having a cavity-registering in .all positions with said passage, and said cavity having a portar-' ranged in one position to partially uncover the inlet. and in another position to com pletely open the outlet.

3. In aflushing valve,'the combination of .saidpassage, and said cavity havin reglstermg' m one therein, a passage lea a valve chamber, a piston valve operating therein,

a passage leading to the valve chamher, an inlet, an outlet, and a plug having a cavity registering in all positions with a port position with t e inlet and in another POSltlOIl withthe'outlet, and an operating mechanism ,for manually controlling the opening of said plug, havin automatic means for closing said plu an -means for adjusting the-amount of sai closlng movement. r

4. In a flushing valve, the combination of a-valve chamber, a iston valve operating fling to the valve chamher, an inlet, an outlet, and a'plug having a cavity registering in all positions with said passage, and said cavity'having a port registering in' one position with the inlet and in another position with the outlet, and 20 THOMAS .1: PAYNE.
