WATEBCLOSET.

The invention relates to water closets of that type in which the tank and bowl are integral and the requisite velocity for flushing is secured by siplionic action. Our prior Patent No. 1,419,328, of June 13, 1922, shows a closet of this type without specific reference to the accessory fittings. The present invention relates to the combination with such general structure of accessories, comprising, first, means for providing a rim flush for the bowl; second. for supplying water to the tank and rim ilush operable under varying conditions and complying with rules for sanitary regulation, and; third, various other features as more fully hereinafter set forth.

In the drawings:

Figure l is a central longitudinal section through the water closet.

Figure 2 is a plan view thereof with the tank cover removed.

Figure 3 is an enlarged section through a portion of the tank and fittings.

Figure 4 is a sectional elevation at right angles to Figure 3.

Figure 5 is an enlarged view of a portion of Figure 4.

Figure 6 is a section similar to Figure 3 showing a modified construction.

In general construction A is the closet bowl provided with a siphonic action outlet comprising the upwardly extending leg B, the return-bend C, the downwardly extending leg D and laterally extending passage E terminating in a downturned connection F to the soil pipe. G is the tank, which is integral with the bowl and is arranged to the rear and at the sides thereof. its bottom H being slightly above the level of the water seal in the bowl and trap. I is a passage formed in an integral portion of the bowl and tank for conducting water from the latter to the ilushing aperture J, which is located below the normal water seal and discharges water into the bowl in a tangential direction. K is an overflow passage connecting with the passage I and extending upward in the tank to above the normal water level therein. L is a hollow rim at the top of the bowl having discharge apertures M for directing streams against the sides of the bowl.

With the structure as thus far described, when water held in the tank is discharged through the passage I and port J into the bowl, it will raise the level therein sufficient 1yl to start siphonic action. This will cause t e very rapid discharge of water from the bowl, reducing the requisite ushing action. t is, however, necessary to provide for refilling the tank and bowl by means complying with all of the requirements of sanitar regulation. One rule which has been a opted b certain communities pro hibits the use o an unvented water supply connection which is in direct communication with the bowl below the overflow level thereof. The reason underlying the rule is that where the water mains are shut oil, there may arise a suction due to siphonic action, which in case of a leaky valve in the supply connection of the closet together with the stoppage in the drain connection from the bowl might draw water back into the main to contaminate the same. 1While this is a most unusual combination of conditions, safety requires the observance of the rule and I have therefore devised a construction which complies with the same. On the other hand, it is equally important that the closet should be noiseless, which necessitates preventing` the suction of air through any vent connection. Such result is accompli shed by the following construction:

N is the water supply connection, which enters from the bottom H of the tank and extends upward therein. O is a valve fitting at the upper end of the conduit N containin the valve P, or so-celled ball cock, whiciittin extends upward to a point above the ove ow level for the bowl, being open at ita upper end for the outward passage of the valve stem which is connected to a lever Q; passing throu h a slotted bearing therein. The lever is fu crumed at one end a bifurcated arm R and connected at its op osite end by a link S to a lever 'lf ulcruine' a bifurcated arm U, which also forms a guide for the lever Q. The lever '.l has an extension T connected with the float ball T.

lil@

The fitting 0 is connected to a downwardly extendin conduit or hush tube V, which conducts t e water to the lower portion of the tank, thereby avoiding noise in refilling. The connection to this conduit is not, however at the level of the valve seat, but is through a lateral extension O of the upper portion of the fitting located above the overdow level, This extension O has a second passage Vf therein which leads to the hollow rim L, and a partition 02 separating the passage V from the passage V rises to a point .still higher than the connection between the passage V and the fitting 0. Thus the water discharged when the valve is lifted from its seat must pass above the overflow level before it can enter the hush tube V, and to a still higher level before entering the rim flush L. Thus when the valve is approaching its seat and the amount of water discharged is small, this entire amount may pass by way of the hush tube instead of through the rim, but when they vvalve "s wider open, water will pass through bothush tube and rim. The proportion between these amounts may be regulated by a valve W, preferably a screw plug having an inwardly extending vain W', which-when turned will variably restrict the passage to the hush tube V.

To comply with the requirement thatthe Water supply connection must be Vented, the tting O is provided with a laterally extending passage O8 adjacent to its seat, which then extends upward to slightly above the overflow level and connects with the laterally extending discharge nozzle 0*. This passage is so proportioned to the other dischar e passages and the nozzle O is so locate in elevation that during the normal operation, water will bedischar ed through the nozzle O4 as Well as throug 1 the`other.

assages. However,- in case of any suction 1n the supply line, the passage-O8 and nozzle. O* will constitute an au' vent, admitting air to the valve seat before any siphonic action can be exerted through the hush tube V or passage V to the ri With the construction as thus farrdescribed, assuming the tank to be-,empty and the valve P to be full open by the dropping of the iioat T, the water passing the valve will be dischar ed through all of the several passages descri ed. Thus a small portion will pass outward through the passage O and nozzle 0*. 'Another ort-ion will be discharged through the hus tube V- while a third portion is discharged through the passage V and hollow rim L to flush the walls of the bowl'. This action continues until the -valve P, due to the rising of the doet, cuts down the amount of water discharged, so

that there is insucient supply to rise overv the partition 0 into the passage P and the whole amount is discharged through 'the hush tube V and nozzle O. Inasmuch as the amount of water discharged is dependent onthe pressure on the line as well as the degrec of opening of thev valve, the regulating valve W may be adjusted so as to obtain satisfactory operation in any particular 1ocality where the closet is'installed. The cutting od of the rim flush before the valve is completely closed has the advantage that all. the water discharged through the valve when approaching 'its seat will enter the tank and not directly the closet bowl, where l it is free to pass through the trap., Thereprevents any sucking of air in through thisnozzle and therefore avoids noise.

Assuming an abnormal condition, in which, rst, the drain connection becomes clogged so that the bowl does not Siphon and fills to the rim second, that the valve P does not completely seat and permits a leakage of water therethrough; third, that-the main is shut'ozand siphonic action occurs, tending to draw' water back through the leaky valve. Under such conditions the first suction upon the waterv in the fitting O will d 'raw in air through'the nozzle 0*, lowering the level in the portion of the fitting O before there is any discharge from the higher level portion O. As soon as the air reaches the valve seat all further suctionpof water is prevented so that under no condition can water in the bowl or'the body of the tank be drawn backward into the main. While the nozzle O operates in this manner under these abnormal conditions, it doesnot permit the introduction of air in the normal operation of they device as the'pressure of water within the fitting O tends to discharge a portion outward through this nozzle instead of drawing air inward.

The discharge of water from the tank G linto the bowl is controlled by a flushing valve X, preferably a `hollow'rubber ball en gaginga seat fitting Y.l The fitting Y is in the form of an annulus having a depending flange Y' engaging the aperture in the bottom H of the tank, which connects with the passage I and a gasketV Y2 surrounding the llange Y forms the seal". 5 The seat Y 1s se cured in position by clamping bolts Y3 en-r gaging ears on dimetrically opposite sides -of the fitting and passing through aperturesy dil same andthe apertured bottom. The fitting Y is further provided with an' upwardly projecting arm Y which extends over the center ofthe Hoat ball, terminating in guide bearings Ys for the stem X of the float ball X.

The operating means for the flush valve comprises a single lever Z, which is fulcrumed npon a pivot pin Z upon a depending arm Z2 clamped to the inner side wall of the tank by a shouldered bushing Zs passing through an aperture in said wall and a clamping nut Z vengaging a threaded portion of said bushing. Through this bushing is passed a rock shaft Z5 having at its outer end a rocker handle Z and at its inner end the crank arm Z" having a hook ZS engaging the apertured end of a link Z". This link passes through an apertured socket Z10 in the lever Z and is headed to form a universal pivotal engagement with said socket. The free end of tht lever Z has a loop Z11 surround-ing the stem X with a relatively large clearance and engaging a looped head X2 at the upper end of said stem.

The parts ]ust described, when assembled, normally hold the lever Z with its loop Z surrounding the stem X between the guides Y and the loop head X2. The rocking of the handle Z in either direction will rock the crankarm Z1 and through the hook Z and link Z9 will lift the lever Z.' This bv engagin the loop Z with the loop head X2 will pul upward the stem X and lift the valve X from its seat. .As soon as the operating handle is released, it, and the parts connected, therewith, will".return to normal position, in which the Iloop Zn. will be out of contact with the stem X so that there is no lateral pressure upon'said stem to interfere 'with its free sliding in the guide bearings Y?. Therefore, as soon as the water level in the tank lowers, the float ball X, will move` downward therewith until it again comes in sealing engagement with the seat Y. The

rocking movement of the lever Z and its actuating handle Z8 is limited by a stop Zn at the inner end of saidlever, which comes in contact with the depending arm Z2. This prevents the lifting of the stem X higher than necessaryior suflicient angular movement of the lever to contact the same with the side of the stem. l

In the modified construction shown in Figure 6 instead of the constantly open nozthe water pressure drops below that required' to sup rt the ball. The ball will then again rop away from its seat to leave the o n vent. This construction prevents d1sclrge of water through the nozale Of during the period in which the tank 1s being refilled through the hush tube V but does not in any way interfere with the normal ventin or under conditions of reduced pressure.

y ne very important advantage of the construction 1s that in case of stoppage in the soil pipe it is impossible to overflow the bowl by repeated operations of the flushing valve. With closets where thei'tank is placed at a higher level than the bowl this may and 4frequently does occur for after each ushing the tank refills with water and if at a higher level will overflow the rim of the bowl as soon as the latter has reached its capacity.,
