WATER -CLOiSET FLUSH-VALVE.

Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed December 3,1906. Serial No. 346,178.

To all whom, it may concern.-

Be it known that 1, JOHN KELLY, a citizen of the United. States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Water-Closet Flush-Valves, of which the following is a specification.

My invention relates to an improvement in the class of automatically-opcrating water,- closet flush-valvesfor controlling the supply of flushing-water to a tank, into which the charge thereof is admitted by depressing the closet-seat to move the valve to one position and from which the charge enters the bowl to flush it as the result of removin the pressure from the seat to permit the va ve to assume its other position.

The obgect of my invention 1s to provide a novei construction of valve device in the class referred to'which shall render it simple and relatively cheap to manufacture and durable and reliable in operation and which.

shall adapt the valve proper to be readily accessible for the purpose of withdrawingit from its casing for rcpacking and for replacing it into operative position therein.

Referring to the accompanying drawings, Figure 1. is a broken section taken at the line 1 on Fig. 4 and viewed in the direction of the arrow, showing my improved valve device interposed between a bowl to be flushed and a tank for receiving the charge of flushing-water, the valve proper being shown in its norrnal position; Fig.2, a view showing the valve device in sectional elevation with the valve proper in the osition to which it is raised W de ressin t e seat to admit a char e of iiushi11g-water into the tank; Fig. 3, abroken section of thevalve device, taken at the line 3 on Fig. 1 and viewed in the direction of the arrow; and Fig. 4 abroken plan view of the rear portion of a closet bowl and seat, show-- ing in cross-section the stem of the valve device in position to be. operated by the seat.

The valve-casing 5 is of general cylindrical sha e and has extending laterally from it a holow arm 6, divided longitudinally by a central partition 7 into passages 8 and 9, the

arm terminating at its outer end in an 11 turned intcrnally-threaded nipple 10 and t e passage 9 terminating at its outer end in a' downwardly-extending internally-threaded nipple 11. As the construction is represented the partition function of the part? termithlnibe flush 'rimfil of a water-closet bow -32 of" nates at the'nipple 11, beyond which it is extended to-form the base of the passage 8 and develops into the nipple 10. Adjacent to the inner ends of the passages 8 and 9 the casing 5 is shown to be enlarged at 12 and 13 to form chambers, between which at l ifits one of the two valves, as and for the purpose here.- inafter described. In the lower part of the casing is formed a partition 15, containing a central guide-opening 16, and beyond which extends the internally-threaded nipple 17 for receiving an annular screw-plug 18, between which and the partition packing 19 is'interposed. The upper end of the casing is closed by a screw-cap 20, which is readily'rernow able to permit access to the valves in the casing, hereinafter described, for facilitating their withdrawal therefrom, as for repacking them and their replacement. -.A nipple 21 extends laterally from the upper part of the casing 5 about a plurality of inlet-openings 22 therein and is adapted to be connected by a pipe 23 with a suitable source (not shown) of water under pressure. On a stem 24:, which extends at its lower end beyond the casing, passing, guidingly throu h the partition 15 and stufiing-box' affords bythe plug 18, are provided at suitable distanceapart the valve 25, surrounded by packing 26 to closely fit the interior of the casing at 14 above the chamber 13, and the upper valve 27, packed with an upwardly extending cup ed gasket 28, closely fitting theinterior of t e casing above the chamber 12. The cap 20 serves to confine the valve-stem in the casing.

In the operative position of the valve device it is coupled at the nipple 10 with a closed tank 29, at the nipple 21 with the sup- 1 ply-pi e 23, and at the nip le 11 witha 30, leading upwar throu h the usual or any suitable variety. On the bowl is hinged, asrepresented or in any other suitable manner, the seat '33, from the center of the hinge of which a finger 34 rojectsbackward underneath the lower end of the valvestem 24-to rise with depression of the seat and affordin the medium by its depression throu h whidli to raise the seat.

- In g. 1 the movable parts of the valve device and the seat are shown in their normal relative positions, to which they are brought by. the'watcrpressure, as hereinafter ICC scribed. By de' ressing the seat 33 the re sultant rise of t 'e stem 2% brings the valve 7 25 into the annular space at 14 to close cum 'munication between the passages 8. and 9 and the valve 27 above the inlet-openings 22 to open communication between the pipe 23 and the assage 8 to the flow of water "from the supp y into the tank 29. While the seat {113111911115 depressed this supply continues to.

fill the closed tank to the extent that its air bound condition will permit. When the lowering pressure upon the seat is released,

thewater-pressure from the supply against the valve 27 and that exerted by the compressed air in the tank through the passage 8 against the valve forces downward the valve-stem against the finger 34 to raise the seat into the osition from which it is ready to be again epressed for effecting introduction into the tank of the next charge of flushingwvater,

. and the charge in the tank 29 flows through the passa e 8past the valve 25 into the passage 9. an thence into the rim 31 to exert its flushin purpose, this flow continuing until the tan is em tied and in condition to re ceive the nextc large as the result of depressing 'the' seat to close communication between the two assages 8 and 9 and open tending hollowarm adapted to be coupled with a flush-tank and containing a partition dividing it into passages open to said casing, one of said passa es being adapted ,tobe coupled to the fins -ri m-of a closet-bowl, an inlet leading into the upper part of the casing and adapted to be connected with a source of water-supply, a valve-stem reciprocably confined in the casing to extend at one end beyond the same and provided with a valve normally closing communication between said inlet and one of said passages for supplying the tank, and with a second valve nor mally opening communication between said passages, for the purpose set forth.
