IMPROVEMENT IN WATER-CLOSETS.

Specification forming partof Letters Patent No. 188,492, dated March 20, 1877 application filed.

- November 1, 1876.

.ing devices as are requisite to illustrate the invention. Fig. 2 is a vertical sectional view thereof through .fr :v of Fig. 3. Fig. 3 is a Vertical sectional view -through or a" of Fig. 2. Fig. 4 is a vertical section-al view of the ushing-valve and devices for flushing the basin,` and Figs. 5 and 6 illustrate certain modifications presently to be described.

The frame or case A is of any suitable construction. The seat A may be hinged or not, at pleasure, and, when hinged or otherwise movable, it may be employed to operate the flushing-valve B by a stem, b; or the usual knob or handle bland stem b2 may be e'mployed for the same purpose, the seat, in the latter case, being fixed or movable, as may be preferred. y

The closet-bowl is represented at G, made with a drain or escape opening, C', leading into a valve-chamber, D, from which latter the usual trapped pipe P leads to the waste. Inside the valve-chamber 'D I arrange a rotary hollow cylindrical valve, D, preferably so that one open end shall discharge directly or indirectly into the pipe P, as illustrated in Fig. 2. This valve, at or near its open end, has between it and its chamber D a packing, d, made water-tight, or practically so, and its opposite end is made close, and with a stem, d1, projecting from its end cap through a stuffing nut, d2, on the end cap. The valve D1 has also a lateral port, e, of suitable size or capacity for the drainage, at pleasure, of the contents of thebowl G. This valve is rotated` by means of a crank, a, affixed to the stem d1, a connection being made to such crank from either operating-stem b or b2, at pleasure, or from both, as presently to be explained. For

greater clearness of illustration I have omitted the flushing-pipe, which leads from the port B2 of the flushing-valve B to the bowl G, in the usual or any desired way. This flushing-valve has a water-pipe connection at B1, Fig. 4. The depressing seat-stem b (when such is used) is connected to the adjacent end of the operating-lever al, which latter restson the head cZ of the piston-stem c1, and this latter, passing through ay stuffing-nut, c3, is screwed into avtapped hole in the piston c. Into the opposite or lower end of the piston c I secure the end of the valve-stem il, whichl latter passes through the chamber n, and carries a valve,i, which, in turn, plays up and down in the perforated barrel nl, and seats upward against a Valve-seat, n2, so as to open and close communication between the supply-pipe B1 and dashing-port B2 through chamber n. A spiral or other suitable spring, 2, serves to close and hold the valve to its seat when not depressed or open by other agencies. The lateral water-supply perforations in the sides of the barrel al are arranged at various points along the length of the barrel, so that the valve i, passing the same like a piston, will open and close themin succession or 'progress ively during its motion, instead of opening or closing all, or a single main supply-port, at

once.

The object of this arrangement is to prevent a too sudden shock, and consequent rey action, from the sudden and abrupt cutting off of the watersupply.

Angularly through the piston c I make a small water-port, o, which crosses the eye into which is screwed the piston-stem cl, such port crossing the eye at such point that it may be closed partially, and to a greater or less degree, byvscrewing the piston-stem c1 in or out. 0n the depression of this piston-stem, piston, and the valve i, water will ow through the porto into the space above the piston, and, escaping slowly through the port owhen the valvez' moves toward its seat, will prevent the too sudden closing of the valve t', and thereby permit the flushing operation to go on long enough to supply the bowl C with the desired quantity of water. As lshown in the drawing, the port o is entirely closed; but inv take the place of the slot h1.

practical use it will be opened more or less by the proper adjustment ofthe piston-stein c1. The joints ot' the valvecase are to be packed in the usual or any convenient way.

A bracket, f, is provided as a fulcrum for the lever al. One end of this lever, as already stated, rests upon the head c2 of the pistonstem c1, and its opposite end, by a loose wrist, a2, is connected with the crank ay of the rotary valve D1. In order to secure the proper throw of this valve I make a curved slot, a3, in the crank a, so that the wrist a2 may, while moving in a vertical line, actuate the crank, so as to effect the partial rotation of the valve D1. Rigidly attached to this same end of the lever al is a weighted block, h, to which I attach, by a clip and socket, the lifting handstem b2, preferably by an adjustable connection, through the use of a slot, hl, so that the point of lift may be varied at pleasure. other slot, h2, is made simply to provide additional means of adjustment when desired, by turning the block IL so that the slot 71,2 shall The function of the weight forming a part ot' this block is to effect a reverse motion of the valve D1 at the proper time and hold it with the port e up, as shown in Fig. 3.

The devices now being in the position shown in Figs. l, 3, and 4, the port e of the rotating valve D1 will be up or on top of the valve, so

. .that the bottom ofthe bowl will be iilled with Water up to the level oi' the port e, and a seal or trap thereby provided in addition to that afforded by the trapped pipe P. Then, by the depression ot' the seatA or the raising of the handle b1, (according to which device is used,) the valve D1 will be rotated till the port e cornes down to the position shown in Fig. 2, and with its lower edge even or about even with the bottom ofthe bowl. The entire contents of the bowl will then pass through the'port e out at the open end oi' the valve D1, and thence into the pipe l?. At the same time and by the same means the iushing-valve is opened with the usual result. The valve D1 being thrown back to the position shown in Fig. 3, the bowl again lls up to the level of the port e, which now is at or near its highest point of adjustment. The annular space between the valve D1 and the case constituting the valvechamber D will be filled with water to the level of the port e, and the rotation of the valve D1 in opening, as well as the low position of the port e in discharging the contents of the closet, enables me to renew the supply of fresh clear water in this annular space, as well as in the bottom of the bowl. The end cap D2 of the valve-chamber D is made removable by the use of. a packed screwjoint, or by other suitable means, so that ready access may be had to the upper open receiving end of thetrap Pin case `any obstructions to the tlow of water should be deposited at any time therein, or in the lower elbow of the trap. rThe opposite cap may, if

The J so preferred, be made removable along with the valve Dl for the same purpose, as well as for renewing, repairing, or cleaning the valve.

As a modification, the piston c may be made hollow, as in Fig. 5, with a port, 0, opening from below, and the graduatingport o, which leads to the space above the piston, may be made by iiling a flat place in the side of the stem c1, at a little distance from the end. With this construction, it' this port o be set so as to give a maximum area of opening, anadjustment by turning the stem either way will diminish the size of such opening, which fea` ture gives an obvious advantage over other similar devices which, in order to lessen the opening, can be turned only one way. The stein, liattened at a little distance from the end, may be used with the piston c and port o of Fig. 4L in like manner and with like useful result.

In Fig. 6 I have shown also a modified arrangement of the rotating valve Dland valvechamber D. In this figure both are in line with the discharge from the bowl, instead of standing horizontally across it, vas in Figs. 1 and 3, and the discharge is through the open end of the valve D1 and out at the port c, (the valve D for such purpose receiving a semirevolution,) instead of through the port e and ont at the open end of the valve. These and other like modifications may be made without any substantial departure from the scope of the present invention.

The form of the valve Dl may be varied `at pleasure, provided only it have a receiving and discharge port properly arranged with reference to the discharge-openin g of the bowl and the wasteconduit, with packing to prevent communication except through the ports,

and be operated by a rotary motion in carrying off the contents of the bowl, and sealing the' discharge-opening of the bowl, and also shall provide for the escape, through the valve, of the excess or overow of water admitted to the bowl in the flushing operation.

Any suitable means of effecting such rotation may be employed. I also believe it to be, broadly, new to combine a ushiug-valve opened by the seat with a bowl, trap, and seal intermediate between the trap and bowl.

And While I claim certain features of the flushing-valve as new, I do not limit myself to the particular construction oi' valve described as an element ofthe combinations, in which it is hereinafter claimed.

It should, perhaps, be added that when the valve D1 is in position for the discharge of the contents of the bowl, the lowest part of the drainports of the valve should, inorder to secure the best results, be fully down to or below the level of the bottom of the drainopening G at its mouth, and when rotated to the reverse position one of its two ports should be above the level of the top or roof' of the mouth of drain opening C and for such purpose one port may always be down to or below the lowest level referred to, and the other be capable, by the rotation of the valve, of being shifted from at or below such lowest level to a point above the level of the top or roof of the basin drain-opening.

I claim herein as my invention- 1. In combination with a water-closet bowl or basin, a valve-oase and rotating .valve arranged in one adjustment, to drain the contents of the bowl or basin through the valve, and, by being rotated to the other position, to seal the discharge-orifice of the bowl or basin, and at the same time leave an openingV through the valve for the escape of the excess of water admitted in flushing, substantially as set forth.

2. A rotary valve, D1, having two communicating ports arranged, with suitable packing, in a valve-chamber, D, and in combination with the discharge-opening G of the bowl or basin C, such ports being open not only when draining the contents of the bowl, but also when the escape-opening of the bowl is sealed, substantially as set forth.

3. The valve-case D, having a removable cap or caps, arranged in line with the trap P, whereby access may be had through the valvecase to the trap for cleaning the same when obstructed, the combination being substantially as set forth.

4. In a waiter-closet ushing-valve, a piston, c, having a water-port entering the piston a little to one side of the tapped eye, and communicating thence with the eye, in combination with a pistou-stem, c1, arranged to regulate the iiow of water through such port, substantially in the manner set forth.

5. The stem c1, attened at a little distance from its end, whereby the area of port-opening in the piston may be varied from a maximum by the adjustment either way of the stem, in combination with a perforated piston having no water way through or past the same, except that water-way the effective area of which is regulated by the stem, substantially as set forth. 6. The valve i, operated in opening by eX- ternal pressure, and in closing by a spring, 2, in combination with a series of ports in the barrel nl, for progressively increasing or lessening the supply, and a valve-seat, n2, to cut oi' the supply completely, substantially as set forth.

7. The curved slot a3 inthe crank a of the rotary valve D1, in combination with such rotary valve, with the loose wrist playing in such slot, and with the vertically-moving operating-stem, substantially as set forth.

8. The barrel nl, having a series of waterinlet ports arranged at different points along its length, in combination with the valve el, which opens and closes such ports progressively or in succession duringv its motion, substantially as set forth. n

In testimony whereof I have hereunto set my hand.
