Application led September 20, 1912. Serial No. 721,370.

To all whom it may concern Be it known that I, EARL G. Wii'rnoUs, a citizen ot the United States, residing at Chicago, in the Sta-te of Illinois, have invented certain new and useful Improvements in Valves, of which the following is a description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates more particularly to flushing valves which operate to control the admission of a supply of water under pressure to a closed tank, and its subsequent discharge from said tank to a water-closet to flush the latter, and has for its principal object the provision of such a controlling valve which may be operated, or set in operation, manually, to admit the supply of water under pressure to the closed tank, and which shall be subsequently operated automatically by the pressure of such water," to discharge the water from the tank to the closet.

My invention may be embodied in various forms, and contemplates broadly such a manually operated and automatically operating valve adapted to be combined with a closed tank and water-closet for the purpose described.

@ne form of embodiment of my invention is illustrated in the accompanying drawings, in which- Figure 1 represents a middle vertical section of the valve with the parts in their normal position of rest; Fig. 2 a corresponding view of the parts in the position which they, occupy after having been manually set in operation and moved to admit the water under pressure to the closed tank; Fig. 3 a horizontal section on the line 3 3 of Fig. I, and Fig. 4l a similar view on the line 4 4.

The same letters of reference are used to indicate corresponding parts in the several views. y

rIhe main portion or body of the valve casing, A., is oi generalY cylindrical form, and is provided at its upper and lower ends with internal screw-threads, those at the lower end to receive the screw cap B by which the lower end of the casing is closed, and those at the upper end to receive the top cap C of the casing and other parts hereinafter described. The interior of the valve casing is divided into what may be termed an inlet chamber' D, an outlet or discharge chamber E, an intermediate chamber F and a piston chamber Gr. Communication between the inlet chamber D and intermediate chamber F is controlled by a valve Il, and communication between the intermediate chamber F and outlet chamber E by a valve I, said valves and the piston J working in the piston chamber G being carried by a single stem Ii. rIhe valve H closes against an annular seat formed for it on the upper side of the diaphragm or partition L which separates the inlet chamber D from the intermediate chamber F, around the opening in said `diaphragm through which thevvalve stem K passes, while the valve I closes upwardly against a seat provided for it upon the under side of the partition MV which separates the intermediate chamber F from the outlet or discharge chamber E.

The inlet chamber D is in communication with the water supply by' the pipe-connection N, and is therefore constantly lled with water under pressure; while the intermediate chamber F is in communication, through the pipev connection O and pipe P, with the closed tank Q, as indicated in dotted lines in the drawings.

The valve is set in operation by admitting water` under pressure from the inlet chamber D to the bottom of the piston chamber Gr through a passage It, such water pressure admitted to the under side of the piston l serving to litt the latter and the valves II and I to the position shown in Fig. 2, the valve I closing against the Seat upon the under side of the partition M and cutting off communication between the intermediate chamber F and outlet chamber E, while the valve I-I is lifted away from its seaton the partition L, placing the inlet chamber vD and intermediate chamber F in communication with each other by the bringing of a cutaway or winged portion K of the valve stem K into the opening in the partition L. Tater under pressure will then pass from the inlet chamber D to the intermediate chamber F, and thence to the closed tank Q and fill the latter to the extent permitted by the air trapped in its upper end,

I will now describe the means for admitting the water pressure Jfrom the inlet chamber D to the under side of the piston J through the passage R, to lift the piston Vand valves to the position shown in Fig. 2, and the means for subsequently causing the water pressure to automatically return them to normal position and discharge the contents of the tank Q through the valve to the closet. The otherwise open upper end of the inlet chamber D is closed by a leather disk T upon which rests a metal disk T of corresponding size and shape, said disks being he-ld in place by a cylinder U, whose lower end bears against the upper face of the disk T. This cylinder is surrounded vnear its lower end with an integral annular flange U whose vertically extended outer edgeis screw-threaded to engage the internalthreads in the upper end of the main valve shell or casing A. A packing ring V is confined between the Linder side of the flange U and a seat formed for it within the valve casing, above the disks T T, to eect a tight joint between said flange and casing. Ports a formed by notches eut in the lower end of the cylinder U ailord communication between the interioi1 of said cylinder and the shallow annular chamber b surrounding it between the upper surface of the disk T andthe under surface of the packing ring V, such annular chamber b being in open communication, at c, with the 'passage'R leading to the under side of the y i piston J at the lower end of the casing A.

As shown in Fig. 3, the passage R consists of atube or Vinelosed duct independent of the sidewalls of the'inlet chamber D where it crosses the latter, leaving said chamber in freeV and open communication, around passage R,.with'the inlet N; while rbelow the bottom of the chamber D, as shown in Fig. il, the passage R is formed in the wall of the casing-A, outside the chambers F, VE and G therein. Y s V The interior of the cylinder U constitutes a'piston chamber W' in which fits and travels a piston X. Screwed into the lower end of this piston, or into a bossd formed upc-n ,its lower end, is the upper end of a valve stein e whoseV lower end passes through i centralV opening (somewhatlarger than the stem) inl the disks T vT and carries a conical valve]E which seats against the under side of the disk T and normally cuts oil' vcommunication between the inlet chamber D and the interior of the cylinder U, or pistonV chamber `W, `above the disks T T. lVhen the piston X and `valve stem e are depressed the valve f is unseated and the inlet chamber Dthereby placed in communication with the interiorv of the cylinder U, and thence through the ports a. and annular chamber I) with the passage R leading to the under side of the piston J at the bottom of the valve casing, and water under pressure is permitted to pass to the under side of the piston J, to lift the latter and the valves H and I to the position shown in Fig. 2. The piston X and valve stem e and valve f are manually depressed, for this purpose, by means which may be now described.

The piston X is provided with an axial bore or passage g which communicates at its lower end, by lateral ports through the boss Z on the under side of the piston, with the interior of the piston chamberlV bcneath the piston. The upper end of this axial passage through the piston is controlled by a relief valve 7L formed upon a valve stein L extending both above and below the valve, the portion below the valve being reduced in size and tapered in torni and extending downward into the passage f/ in the piston, and the portion above the valve being enlarged and proj ect-ing upward some distance above the top ot the piston X. The valve /L and its stem 7L. have liniited vertical play with respect to the piston. so that the valve may be seated and unseated, and are held in place by a screw cap if surrounding and screwed upon the upper end of the piston, the interior of said cap, surrounding the valve It above the upper end of the piston, constitutin a small cha mber whose communication with the chamber lV beneath the piston (through the axial passage g and ports in the boss (l) is controlled by the valve t. This chamber within the screw cap z' communicates by the ports y' with the exterior space surrounding said cap, and thence with an escape or drainage passage Y formed in the wall of the valve casing A and communicating at its lower end with the discharge S.

rThe top cap C of the valve casing. which screws at its lower end into the internally threaded upper end oi the body A of the y casing and is provided with an annular flange between which and the upper end oi the body of the casing is confined a packing ring, is provided with a laterally projecting internally threaded tubular or cylindrical portion C whose open outer end is closed by a screw cap C2. Fitting` within the inner end of such cylindrical. portion C ot the cap C is a disk A which is provided with an outwardly extending hub or stein A.B which lits in a guide-way formed tor it within an inwardly projecting sleeve c on the screw cap C2. The disk A is provided upon its inner side with a central conical recess a in which fits the outer end ot one arm B of a toggle-lever, the outer cud o whose other arm B2 lits in a similar conical or concave recess a? formed for it iu the wall of the cap C. A spring D confined within the cylindrical portion (l et the cap C, and surrounding the stem or huh AL Aof the disk A', presses the latter inward and serves to yieldingly hold the togglelever in either of its o pposite positions to which it may be moved. ln the position of parts shown in Fig. l the toggle-lever is bent upward and its joint immediately underlies the lower end of the stem E of a push-button E2, by depressing which button and stem the joint of the toggle may be forced downward, against the resistance of the spring D", to its opposite position, shown in Fig. 2. New, when the joint of the toggle is thus Jforced downward by depressing the push-button E2 it contacts with the upper end of the valve stem t and forces the piston X downward to the position shown in Fig. 2. rlhis serves to unseat the valve and place the inlet chamber D in communication, through the central openings in the disks T T', chambers W and b, and passage lt, with the piston chamber G beneath the piston il, so that water under pressure will be admitted to the under side of the latter; and inasmuch as its area is very much larger than the effective area ot the upper side oi' the valve H, which is exposed to the pressure of the water in the chamber D, said piston and the valves l-l and l will. be quickly lifted to the position shown in Fig. 2, where the valve i will operate to cut-oil' communication between the intermediate chamber F and discharge chamber l, while the inlet chamber D will be placed in communication with the intermediate chamber F around the cut-away or winged portion K of the valve stem K. inasmuch as the intermediate chamber F is in open communication, through the pipe connection and pipe P, with the closed tank Q, the latterl will be at once iilled with water under pressure to the extent permitted by the air within said tank, which will be confined and compressed in the upper end of it.

The pressure of the water within the chamber D will be somewhat reduced by the opening of the valves f and H and the iow of water :from said chamber to the piston chamber G in the bottom of the casing and to the closed tank Q, but as the latter becomes iilledwith water (to the extent permitted by the air Within it) the normal water pressure will be restored in the inlet chamber D and in the passages and chambers in communication with it at such time, including the chamber W beneath the piston X, which latter has been depressed to the position shown in Fig. 2 by depression of the push-button E2; and the strength and adjustment oit the spring D, which yieldingly holds the toggle-lever in its opposite positions, are such that when the water pressure within the chamber "W beneath the piston X is restored to approximately its normal degree it will lift the piston X against the resistance of the spring D", and restore it to the position shown in Fig. l, thereby again seating the valve f and cutting oil' any further communication of the inlet chamber D and water supply with the piston chamber l/V and likewise with the piston chamber G in the bottom of the casing, and the water under pressure in those chambers will thereupon slowly escape through the piston X (by the ports formed in its boss (l, its axial passage g, and the ports 7' in the cap i) to the interior of the cap C surrounding the piston X and upper end of the cylinder U, and thence through the drain passage Y to the outlet S. Such escape of the water from the chamber WV and passages and chambers in communication with it is prevented, during the time he parts are in the position shown in Fig. 2, by the closed position of the valve 7i, which is maintained in its closed position by the pressure of the spring D exerted upon it through the toggle-lever; but when the piston X is lifted by the water pressure beneath it, as heretotore explained, the toggle-lever will be iirst straightened out, and then, as soon as its joint passes upward beyond its dead center, it will be instantly sprung upward by the pressure of the spring D to its normal position, shown in Fig. l, and its joint be thereby carried away from the valve stein 7b,

leaving the valve It free to be lifted by the ,A

water pressure exerted against its under side through the axial passage g in the piston X.

The escape of the water under pressure from the piston chamber G beneath the piston J, when the parts which have been c cpressed by the push-button FF are restored to normal position in the manner above eX- plained, will relieve the pressure beneath the piston ll and permit the then preponderating pressure upon the upper side of the valve l to force said valve and the parts moving with it downward to normal position again, thereby placing the intermediate chamber F and the closed tank Q in communication with the discharge outlet S of the valve casing, so that the water in the tank may flow through the valve to the closet to flush the latter. This iow of water from the closed tank to the closet will be supplemented by greater or less amount from the inlet chamber D and direct source of supply during the time the valves H and I and piston J are returning to normal position. This return movement of such parts may be regulated as desired by controlling the rate of escape of the water from the piston chamber Gr through the passages provided tor such escape, and during such return movement of them water will iow Jfrom the inlet chamber D to the intermediate chamber F and discharge passage S, around the cut-away or winged portion K of the valve stem K, until the parts have moved downward far enough for the cylindrical portion of the rvalve stem K, above such c'utaway portion, to enter and substantially close the valve opening in the partition L. The valve stem K is provided with a tapered enlargement K2 above the valve I, the purpose of which is to somewhat restrict the escape of water from the chamber F at the beginning of the opening movement of the valve I, and to increase the freedom of its escape as the valve moves downward, and asthe pressure of the water iiowing through the chamber vconsequently diminishes, so as to produce a more even fiow of water to the closet and a more Auniform flushing of it.

Inasmuoh as the piston X must be held in its depressed position, Fig. 2, against the resistance of the water pressure in the cha-mber W' beneath it, during the timethe closed tank is being filled with water, and inasmuch as it must be again lifted to normal position by the water pressure in the chamber IV when such pressure has been restored to its normal degree, Vthe pressure of the spring D, which operates to hold the piston in depressed position when the parts are in the position of Fig. 2, may have to be varied with differing water pressures, and provision for such variation or adjustment is made in the construction illustrated by means of the screw cap C2 against which the outer end of the spring D bears and by which it is confined within the cylindrical portion C of the cap C. By screwing this cap C2 inward the pressure of the spring D may be increased, to adapt the valve for use with a higher water pressure, and by screwing it outward the pressure may be decreased to adaptthe valve for use with a lower vwater pressure. By means of such adjustment or variation of the tension of the spring D Vthe valvemay also be set for operation at any desired pressure below the maximum water pressure and the flushing action of the valve be thereby regulated as desired. A lock-nut 02 is provided for locking the cap C2 in its various adjusted positions. Y

As will be understood from the foregoing description, I have provided a fiushing valve, for use in connection with closed tanks and water-closets, which may be set in operation by the simple depression of a push-button, and which will thereafter operate automatically t0 admit water from the source of supply kto the closed tank until the latter has become filled to the extent permitted by the air confined within it, and which will then further operate automatically to discharge the contents of the closed tank through the valve casing to the closet to fiush the latter. So far as I am awareI am the first to produce a valve, of any construction, having this mode of operation or capable of producing the results described, or a valve of any kind controlling the admission of water from the source of supply to a closed tank and operating automatically to discharge the contents of the tank to the closet when the pressure in the tank has reached a predetermined degree; and I desire to claim as my invention a valve having such mode of operation and such capacity, as broadly as may be done.
