TO SAID TEAHEN' WATER CLOSET Application filed March 9,

The invention relates to water closets of the type forming the subject matter of our prior Patent No. 1,419,328 issued June 13, 1922. The distinguishing feature of this type is that the tank holding the flushing water is integral with the bowl and consequently the water head is comparatively low. However, a high velocity is imparted to the water discharging from the tank to the bowl in through siphonic action, thereby effecting a thorough flushing with a practically noiseless action. Another feature of this construction is that the water from the tank is admitted to the bowl so as to cause a whirling or centrifugal action. This action must, however, be restricted as otherwise it would defeat the operation of establishing the siphon, either by too greatly retarding the flow of water into the trap or possibly forming a vortex, admitting air into the trap to break the siphon. Thus while the cleansing of the bowl is facilitated by a strong centrifugal action, such action must be controlled to of breaking the siphon.

It is the primary object of the present invention to obtain a construction and method of operationwhich effectively controls centrifugal action and insures the starting of the siphon. This we have accomplished by dividing the water from the tank, admitting a portion into the bowl so as to cause a whirling action therein, and utilizing another por. tion for forming a jet of water directed upward in the upwardly extending leg of the siphon trap. The invention therefore consists in the construction and method as hereinafter set forth.

In the drawings: 40 Figure 1 is a plan view of our improved closet;

Figure 2 is a longitudinal section there through; a Figure 3 is a cross section.

Figure 4is a section on line 44 of Figure 2.

The general features of our improved construction are sim'lar to those of the former Patent No. 1,419,328. comprising a bowl A supported upon a. pedestal B containing the the point where there is no danger ing of the water within the bowl further in- 1931. Serial No. 521,257.

usual siphon forming return bend B and having formed integral therewith a tank C which extends across the back and overlaps the sides of the bowl. The tank extends upward above the bowl but preferably for only a short distance as it is only necessary to have suflicient head to establish the siphon and any further elevation of the water level is superfluous and does not to any appreciable extent add to the velocity attained by siphonic action. The bowl D of the tank is also approximately at the level of the water seal in the bowl, this giving the maximum capacity of flushing water and any extension of the tank below this level being useless. Water is conveyed from the tank to the bowl through a channel E which extends beneath the bottom D and discharging tangentially into the bowl through an opening F therein which is located below the level of the normal Water seal. The ri'm G is also provided with an annular channel H for the admission of water used as a rim flush.

The parts thus far described are substantially the same as in our former patent, and in operation the flushing is effected by lifting a flush valve (not shown) which admits water through the channel E and aperture F into the bowl, raising the level therein sufficiently to estab sh a siphon in the return bend B. This increases the velocity of discharge from the tank to the bowl but without the noise which usually accompanies discharge from an elevated tank while the whirlcreases its cleansing efficiency.

To insure the quick forming of the siphon we have provided an auxiliary water discharge passage F which drops below the level of the passage E and is directed upwardly into the upwardly extending leg of the trap B. Water is diverted into this passage F by means of a baffle J extending upward into the passage E so that a part of the water fiowing through the latter passage is deflected downward and around the bend and through an aperture F into the trap B to be directed upward as just described. This produces a jet of water ascending in the leg of the trap B so as to more quickly establish the siphon. 100

As a consequence we obtain the maximum efliciency in cleansing the bowl through the whirling of the water therein with certainty that the siphon will be quickly established and not broken untilthe water is completely discharged from the bowl.

To provide an overflow for the tank a channel H is formed integral with the rear wall of the tank, being open at the top and at its lower end connected into the channel E. When the flush valve is opened there will be a tendency for the water entering the channel E to flow in both directions, thereby causing a rise of water in the channel H and nossibly slopping over the top. Such an efl'ect is prevented by placing in the channel E between the same and the channel H a baflle I which will interfere with this back flow of water. The baffle is, however, provided with a slot I extending downward therethrough which permits drainage of water therethrough which otherwise would be trapped. Thus the arrangement is one which does not interfere with the overflow function and prevents back flow through the channel.

As the specific fittings used for controlling the admission of Water to the tank and the discharge therefrom form no part of the present invention, description and illustration of the same is omitted.

What we claim as our invention is:

1. The method of flushing siphonic bowl closets consisting in establishing a gravity water head not greatly above the normal water seal, discharging water from said head and dividing the water so discharged to direct a portion thereof into the bowl and another portion to form a jet for establishing the siphon.

2. The method of flushing'siphonic bowl closets consisting in establishing a gravity water head not greatly above the normal water seal, discharging water from this head towards an inlet into the bowl and in diverting a portion of the water discharged to form a jet for-establishing the siphon.

3. The method of flushing siphonic bowl closets which consists in establishing a gravity water head. not greatly above the normal water seal, discharging water from said head with a portion directed tangentially into the 'bowl and in diverting a porbowl, a deflector in said discharge passa and a passage for the deflected water terminating in a jet directed upward into the siphon trap.

6. A water closet comprising a siphonic action bowl, a tank connected therewith for forming a comparatively low water head, a discharge passage from said tank to said bowl, a deflector in said discharge passage for retarding the flow of water therethrough into the bowl and 'a passage for the deflected water forming an upward y directed jet into the siphon trap.

-7. In a water closet, the combination with the bowl, a tank integral therewith, a channel beneath the tank communicating with the bowl, an overflow channel for the tank communicating with the channel beneath the same, and a baflie between said over flow channel and the channel beneath the tank for the purpose described.

8. In a water 'closet, the combination with the bowl, a tank integral therewith, a channel beneath the tank communicating with the bowl, an overflow channel for the tank communicating with the channel beneath the same, and a baflle between said overflow channel and the channel beneath the tank' for the purpose described, said baflle being provided with a drainage slot therethrough.

In testimony whereo we aflix our signatures.
