Figure 3 is a vertical section therethrough.

Figure 4 is a sectional plane of the rimlush.

Figure 5 is a section on line 5--5 of Fig- In/l the construction of then patent above referred to the flushing tank is integral with the bowl and located so as to be within the space limits of standard roughing-in d1-` mensions. The flushing is eii'ected by introducing water from the tank into the bowl below the water seal and in suiiicient volume to raise thelevel within the bowl so as'to establish siphonic action. This is the equivalent of raising the head so that a high velocity is imparted to the water entering the bowl and passing through the trap to accomplish a thorough flushing. The patent referred to also shows a tangential` arrangement of the passage for the water into the bowl to impart a rotary movement to the mass of water therein. This is for the purpose of establishing centrifugal and centripetal action within the bowl but we have discovered that such action must be accurately controlled in order to produce benelicial results. Thus, if the rotary motion is.

too high in velocity, it will throw the water up the sides ofthe bowl and produce a vortex that defeats the object of establishing siphonic action. On the other hand, if no rotary movement is imparted to the mass, the flushing action is not as eilicient.

It is one of the features of the present improvement that the water entering the bowl is so directed and controlled as to -produce just the requisite velocity o f rotation. This is such that centrifugal action of the water will produce a centripetal force for plan view in theA `carrying the mass to the centre of the bowl so that 1t is first drawn ,through the trap.

of the rixn, this water being directed downy ward against the walls of the bowl to roduce an equal washing eil'ect on all portions thereof. Other features of our improvement willbe referred to specifically hereinafter.

In detail A is a bowl which is supported on a pedestal B having arranged therein the' trap comprising the upwaidly and rearwardly extending leg C., the downwardly extending leg D and a laterall extending portion E which connects with t e soil pipe. The tank F extends trap B and also laterally to a greater width than the bowl, its walls taperin forwardly` to merge into the walls of the owl. Surrounding the top of the bowl is a rim G which is hollow and provided with an inwardly extending portion G on its underside and a series of jet apertures H which are inclined to be directed 4against the walls of the bowl. At the rear of this rim is an inlet passage I extending into the tank and adaptedI for connection with the water supply fitting. Within the hollow rim and extending around the rear portion thereof is a series of baille plates J separated from each other suiiicientlyfor the passage of a small amount of water therebetween butv directing a large portion of the stream to the opposite sides of the rim so as to insure substantially equal distribution to all of the jets H. The bottom of the tank F is preferably located but slightly below the level of the water seal in the bowl and has provided therein at one point? an aperture K which connects with the passage L extending at one side of the pedestal and communicating with a port M in the side of the bowl. As shown in Figure 5 the passage L in the portionA communicating with the port M is so fashioned that the stream of water entering the bowl is directed toward the central portion of the mass but slightly to one sideof the geometrical centre. This will produce a whirling of the water which however is limited in velocity so as to avoid interference with the establishment of siphonic action.- Nevertheless the rotary movement is'suiilrearwardly from the cient to produce a centrifugal and centripetal action above referred to which great y assists the flushing action. The passage L is also connected with an upwardly extending passage N within the tank F, this rising to a point sli htly above the normal level Within the tarili but lower than the top of the rim of the bowl. Thus, should water rise to an abnormal height due to a leaky inlet valve or any other cause, it could overflow through the assage N and escape by way of the bowl and) trap.

The port K which connects the tank with the assage L is controlled by a valve O whic engages a seat member P. This seat member is preferably provided with a down turned flan e P extending into the aperture K, an a gasket Q, between the seat `imemberA and the bottom of the tank forms the seal. The seat member is secured in position by bolts R which pass throu h apertures in the bottom of the tank an engage nuts that are located in the passage L. Gaskets S normally prevent any leakage around these bolts but should leakage at any time occur, it would be into the passage L which has free connection with the drain. The seat member P is provided with an upwardl extending post T at one side thereof whic is turned inward at its upper end and is provided with guide bearin s U for engaging the stem. O of the valve V is an operating lever fulcrumed at V upon the bracket W at one side of the tank and havin at its free end a loop V2 for loosely engaging the stem O below the loop or head Oz at the upper end of said stem. The lever V may be loperated by a handle X which has a crank arm X connected by the link Y to said lever.

Water is supplied to the tank and to the rim through suitable connections which form the subject matter of another application for patent and therefore will not be described in detail. Generally these consist of an inlet conduit Z passing upward through the bottomof the tank and having at its upper end a fitting Z containing the ball cock. This fitting 1s connected with the downwardly extending discharge conduit or hush tube Z2 and the laterally extendin conduit Zs leading to the passage I in t e rim. There is also a vent passage Z* so located that it will normall discharge water when the ball cock is open but will act as an air vent in case of suction in the supply conduit Z.

In operation, the ball cock automatically admits water to the tank up to a predetermined level and also when open supplies a limited quantity of water to the hollow rim. The flushing is effected by operation of the handle X connected to the crank arm X and link Y, which lifts the stem 0 and valve O connected therewith permitting the water to flow through the passage L and port N into the bowl and this raises the level within the bowl to a point where sihonic action is established whereupon the ull volume of water in the bowl and tank is ra idly discharged at high velocity. This, coup ed with the centrifugal and centripetal action above referred to will effect a thorough cleansing of the bowl. At'the same time, the lowering of the level within the tank by opening the ball cock supplies water to the hollow rim and the baffles J therein produce an cqual distribution around all sides of said rim. This in turn produces jets of equal force continuing in actionduring the emptying of the tank and the refilling of the same and furnishing water after the breaking of the Siphon for reestablishing the water seal.

What we claim as our-invention is:

l. In a water closet, the combination with a bowl, of a flushing tank integral with said bowl and having an apertured bottom approximately at the level of the water seal in said bowl, a channel beneath the bottom of said tank extendi to the bowl and opening therein beneat the normal water seal,a flushing valve controlling the aperture in said bottom, and an extension of said channel rising within the tank to above the normal water level therein and open at its upper end to constitute an overflow.

2. Ina water closet, the combination with a bowl, a flushin tank integral therewith of a valve control ed channel connecting said tank with said bowl at a point below the water seal of the latter, and an extension of said channel rising in said tank to a point above the normal level constituting an overflow connection in constant communication with the bowl.

3. In a water closet, the combination with a bowl, a flushing tank integral therewith, of a channel connecting said tank with said bowl having a port opening through the bottom of tlie tank, a valve for completely closing said port, and an extension of said channel rising to a point above the normal water level in the tank and integral therewith constituting a normal open overflow connection.

4. In a water closet, the combination with a bowl, and a tank inte ral therewith havin a port opening through the bottom thereo and a channel connectin said port with the bowl extending upwar to form an overflow for the tank, of a fittin within the tank surrounding said port, a oat valve engaging a seat on said fitting, a stem rising centrally from said float valve, an arm risin from said fitting and forming a bearing wit which said stem is slidably engaged, and a trip lever within said tank ,directly but loosely engaging said stem to lift said valve from its seat without lateral displacement of said stem.

5. In a water closet, the combination with Lemans a siphonic action bowl, of a ushing tank for forming a gravity head between thewater seal and the top of the bowl, means for discharging water from said tank into the lower portion of the bowl to establish siphonic action, and means for directing the water entering the bowl to produce a whirling' action therein limited in velocity to avoid interference with the establishment of siphonic action.

6. In a water closet, the combination with a siphonic action bowl, of a Bushing tank for forming a avity head between the water seal and e top of the bowl,vmeans for discharging water from said tank into the lower portlon of the bowl, to establish siphonic action, said passa having a termmal portion communicatm with a port in they side of the bowl and Iieing so fashioned as to direct the water toward the central portion of the mass but suiiciently at one side of the geometric centre to produce a whirling action of limited velocity.

In testimony whereof we aix our signatures.
