- To all; whom it may concern.-

Be it known that I, J OHN'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-Valve Devices, of which the following is a specification.

My invention relates to an improvement in the class of valve-devices for use in controlling the supply of water to the flush-rim of a water-closet bowl for flushing the latter;.

admitting the supply of flushing water to the tank, and Fig. 4, a similar view of the same showing the valve-device in its condition of shutting off that supply.

The valve-casing 5, which is of general cylindrical shape, is shown to be formed of tn bular sections, coupledtogether, with an enlargement forming a chamber 6 in the lower section, a narrower enlargement forming a chamber 7 below the chamber 6, below fwhich is the chamber 8 above the lowermost and narrowest chamber 9, with ashoulder 10 between the two affording a stop. A nipple 12, leads from the chamber 9 about a adapted to be connected with a suitable supply (not shown) of water under pressure; a

draining-nipple 14 leads from the chamber 8 and-is adapted to be connected with a trap, hereinafter referred to; a nipple -15 leads from the chamber 7 and is adapted to be connected with a flush-tank 16, which is preferabl' aiclosed tank, as representedin Fig. 1 an a nipple 17, which is adapted'to be connected with the flush-rim of a water-closet bowl, leads from the upper art of the casing.

. represented, the nipp e 17 forms part of the uppermost section of the casing 5, which is cl osed at itsupper end by an annular screw-cap 18 containing a stuffing-boxl9; and this upper section also has extending from it, backwardly, a curved seat-su portlower end.

ngarm 20. The casing is also close atwits Within the casing is reciprocably confined a valve-stem21, the upper portion of which is a diametrically enlarged section to adapt it to fit guidingly in the annular cap 18 and stuffing-bore 19, through which it works, and

which is screwed, to render it adjustable, on

the upper end of the lower section of the stem where it is provided with a hexagonal circumferential flange 23, afiording a stop for a purpose hereinafter-mentioned. Adj acent to the chamber 6, the rod carries rigidly a circumfere'ntially packed valve 24, closely fitting the interior wall of the casing below that chamber; on its lower end the stem carries a valve 25 closely fitting about the interior of the chamber 9, and between these two valves the stem is expanded intoan elongated hollow section 26 provided between its ends with circumferential flanges 27 and 28 spaced apart to form between them a circumferential recess 29 for confining an 31111117 lar band 30, of rubber or other expansible packing material, constituting a valve.

Openings are provided at 31 and'32 in the expanded section 26, above and below the recess'29, in which latter are also provided a circumferential series of port-like openings 33.

To apply my improved yalve-device inthe operatlve position represented in Fig. l, the

nipple 17 is suitably coupled with the flushing-rim of a water-closet bowl 34rising from a floor 35, below which extends the sod-pipe 36 containing a trap 37 having connected with it the draining-nipple 14; and with the tank 16, represented as occupying a position below the fioor 35, is coupled the nipple 15. A seat 38has an arm 39 extending from it, at which it is hinged to the curved arm 20, and from the hinge extends a rigid arm 40 having a-weight 41 suspended on it tending to raise the seat to the position in which it is represented. vThe upper end of the valve stem registers with the-seat-carrying arm 39.

The operation is as follows: With the parts of the valve-device in the relative positions t1: ey are shown to occupy in Fig. 4, lowering the seat and pressing the arm 39 against the upper projecting end 22' of the stem, depresses the latter with the result of lowering the valve 25 below the plane of the inletports 13,0f bringing the valve 30.into posi,

tion toclose the outlet in the nipple 14, and the valve 24 into position to close communication between thechambers 7 and 6. Thus water from the supply thereof may enter thev of the supply from loss by draining.

chamber 9 by Way of the nipple 12, course through the valve 30 about the expanded stem-sectien 26, and thus enter the chambers 8 and 7 to flow from the latter, by way of the nipple 15, into the tank 16 and fill it to the extent permitted by its air-bound ccndition. In flowing through the valve 30, the water, by its pressure exerted through the holes 33 against the interior surface of the packing 30, expands the latter to cl'esel; cover the drain-outlet and thus prevent any then the pressure is removed from the seat it rises under the stress ol" the weight 41, thereby relieving the valve stem from depression. As the result of this release of seatpressure, the pressure of water in the tank 16 exerted against the valve 24 raises the stem until arrested by engagel'nent of the stop 23 thereon with the cap 18, thereby bringing the valve 25 above the plane of the ports 13 to shut ell the water-supply to the valvealevice, and bringing the valve 34 into the chamber 6 to permit the discharge from the tank to pass that valve and [low upwardly through the casing and nipple 17 into the flush-rim of the bowl to tlnsh the latter. in the rise ml the valve-stem, the valve is carried above the outlet in the tlraining-nipple H, to uncover it. and permit any remnant of water in the tankand casing to drain oil by way of the expanded hollow stem-section 26, thus insuring thorough (Vtttllttllflll ol the valve-dtwice .ol water against its freezing therein.

18 may be increased or reduced, to vary accordingly the play of the valve 2 1, which when permitted. to rise more or less closely to the upper end of its. containing chamber 6 prolongs the llushing operation by reducingthe llow of water pastit.

What I claim as new and desire to secure by Letters Patent is- In a \"al\'ede\-'1ee of the character described, the combination ol a casing contain- .ing an inlet near one end adapted to be con nected with a watersu ')pl v, an opening adapted to be connected with a flush-tank, an outletadapted to be connected with the flush-rim of a water-closet bowl, and a drainoutlet. at valve-rod reciprocably confined in said casing and provided with valves for controlling said inlet, opening and outlet respectively, and constructed and arranged to be normally upwardly pressed by the watersupply and in such position afford a passage from the tank to the rim, and an adjustable stop on said red engaging said casing to limit its upward movement under the water-pressure For controlling the flow of water from said tank to the rim.

JOHN KELLY.
