PHILIP imas, OF'DA'YTON, omo.

wA'rEn-chosn'r VALVE.

- one embodiment of my invention selected by me for the purpose of illustrating the same, and a slight modification thereof, and said invention is fully disclosed in the fol lowing description and claims.

My present invention relates particularly to that class of flushing apparatus whichis used most largely where the water supply is comparatively small so that the water supply pipe with which the apparatus is connected does not furnish the water in sufficient quantity to enable it to be used directly from the supply pipe for flushing purposes, and in this class of devices it is customary to employ a flushing tank which is supplied with water fromthe water supply pipe, or main and when the flushing action takes place, the flushing is accomplished by means of the water discharged from'said tank.

My invention provides for controlling and operating the valve mechanism of the ap paratus 1 means of the pivoted closet seat and includes among its novel features,means whereby a very light spring may be employed for normally holding the water inlet valve upon its seat, thus permitting the valve to be raised by a comparatively small amount'ot force exerted upon the valve stem in opposition to said spring, thus relieving the spud which connects the valve mechamsm with the porcelain bowl, or other connecting means from transverse stress, which tends to injure the same or break the porcelain away where a very heavy spring is employed.

My invention also contemplates a novel valve construction for substantiallybalancing the water pressure and facilitating the movement of the valve in either direction and more specifically and in its preferred form,

Specification of Letters Patent.

' Application filed October 30, 1913. Serial No. 798,299.

my invention also contemplates the provision cf connections independent of the main flushing connection for supplying water to the jet and also preferably to the rim of the bowl while the seat is in its lowest 0 position so as to moisten the walls of thebowl, break the water seal of the bowl, and discharge an injector like stream from the jet through the empty trapand soil pipe so as to create a strong suction therethrough,

which will efiectually withdraw air continu'- ously from the bowl and thoroughly ventilate the same during the use of the apparatus and while the seat is depressed. The importance of this ventilating feature can hardly be over-estimated. By its use. an ap paratus of this character can be installed in lavatories, in hospitals, and other places without the slightest possibility of contaminating the atmosphere of the room in which .75

it is installed so that the closet becomes as innocuous as any ordinary piece of furniture. It may thus be installed, for example, in the bedroom of a hospital or of an invalid in a private house or in many other locations ,80

where the ordinary toilet apparatus would be extremely objectionable and unsanitary, without any inconvenience and without impairing the purity of the atmosphere of the room. i

In a former application for Letters Pat ent of the United States filed by me on or about July 19, 1912, I have disclosed the broad idea of ventilating structure in connection with a specificform of valve mecha;

nism, especially adapted for use where prac tically unlimited volume of water supply is available, such as in large ofiice buildings and other buildings where a suflicient supply of water to effect the flushing without 96 the use of an intermediate tank can be had: J and my present invention is particularly designed to extend the advantages of this invention to that type of apparatus intended for use where a comparatively small supply of water is obtainable and the intervention J of a supply tank is necessary.

It will also be understood that this apparatus can be utilized for positively ventilating the room in which it is installed, for it the inlet valve is open, as by depressing the closet seat by means of the hand or otherwise without any use of the closet, the water seal will be broken, as before described, the

suction j t will be discharged through the emptying trap and" will operate continuously so long as the valve is held open, thus positively withdrawing large volumes'of air from the room and discharging them through the soil pipe. The operation of the device may be continued for a suflicient -period to thoroughly ventilate the-room, such as a hospital room or the room-of an invalidin a private home, or any other room or apartment in which the apparatus ;is installed. Obviously the air withdrawn from v the room bythe suction gof the ventilating jet will necessarily be replaced by fresh air entering ,.t-hrough the doors, windows, or otherwise from outside the room. It will thus bese en that this [ventilating feature of 'my invention not only prevents the contami nation; of the airby the use of the ap aratus ng apparatus for changing the atmosphere in the ordinarpmanner, but may e em-- .ployed independently as an active ventilatof the room, if desired.

' k '1' Referring to. 'the' accompanying drawing,

, Figure ,1 represents 'a sectional view of a i 25.

closet. bow-l providedwith my improved flushing and ventilating apparatus. Fig. 2

. inbefore referred to is omitte Fig. 3 is a view raised or open position. Fig. 4 represents .51 sectional view through the valve and casmg on the line 4l of Fig.2 looking in the I direction of the arrows.

Fig. 5 is a sec-' tional view of a modified form of valve and casing in which the ventilatin feature heremounted in the cylindrical portion 14 so as but the other advantageous features of the construction are retained. I

Referring to the drawings, 1 represents the bowl provided with the bowl rim flush passage 2, trap 3, and discharge 4: connecting with the soil pipe. I

5 indicates an aperture provided in the bowl structure for the insertion of a jet pipe at the lower end of the trap portion communicating with the bowl proper and the bowl is also provided with an inlet aperture 6 connecting with the rim aperture 2 to receive the spud or main flush pipe connection, a second spud receiving vaperture 7 connecting with the rim aperture 2, and an inlet aperture 8 at the'lowe'r part of the bowl for receiving the spud through which the jet pipe connection is made.

10 represents. the valve casing which is open at the top and bottom and'iis provided on opposite sides with apertures substantially in line with each other. The bottom aperture is preferably the inlet aperture, although it is obvious that the valve mechacould be turned upside down without departing from the spirit of my invention. The bottom portion of the valve casing is.

in this instance exteriorly screw threaded to receive a clamping nut 11 provided at its ed to connect it with the water inlet pipe and the upper end of said collar is rovided with a reduced aperture 12-and wit an annularvalve, the seat 13 surrounding said reducedapertu.re,.-. .The interior of the valve chamber'is provided,with a cylindrical portion 14: which forms a guide for the cylindrical valve. body hereinafter referred to, the said cylindrical portion being provided with an aperture. 15.0Qmmunicating with the aperture 16 on oneside-of the valve casing which is! connected withthe main flushing aperture ,6 as he reinafter described. The aperture 16 is shown in this instance as internally screw threaded. The valve casing 10 is provided as before stated with an aperture on the oppositeside of the' casing,

' here indicated at 17, which is also shown internally threaded, and the cylindrical portion 14 extends upward into that portion of the valve body opposite the lower portions of the

apertures

15 and 16. A web 18 extends from the upper part of the valve body to the upper part of the cylindrical guiding a portion across the upper portion of the aperture'.16 so that the communication between the aperture 17 and the aperture 16, through the valve casing, must be through the upper part of said cylindrical guiding portion and through the lateral aperture 15; therein, as clearly'shownin Fig. 2. F j

A hollow cylindrical valve ,body 20, is

to be capable of sliding easily, vertically therein, said body bein'g'olo'sed at its lower end and provided with a valve 21 on its,

lower face, the said valve being preferably composed of rubber, fiber erother suitable material held in a recess formed in the bottom portion of reduced diameter with which the bottom of the valve body is preferably provided, said valve coacting with the valve seat 13 before referred to so as .to open and close the water inlet aperture 12, A portion I of the valve casing indicated at 22 below the cylindrical guiding portion 14 is of slightly larger diameter than the valve body as shown and the valve body is provided near the lower end of its hollow cylindrical portion with apertures 23 in its walls, the combined areasof'said apertures beingpreferably somewhat less than the area of the aperture 12 in the preferred form of my invention, so that a portion only of the water admitted'through the aperture 12 will pass through said apertures 23 into the interior of the valve body and upward therethrough, when the valve is'in raised position as hereinafter described. The valve body is provided With a vertically disposed stem 30 M ran? top aperture therein, the said aperture be- 27 represents a coil spring which preferably surrounds the valve stem, the lower end engaging the bottom of the interior of the cylindrical valve body, and the upper end engaging the washer 26, thus compressing the spring and also compressing the packing 25 between the washer 26 and the upper end of the recess in the plug or cap 24.

The diameter of the water inlet aperture 12 being small, a comparatively light spring can be used tohold the valve 21 seated on the valve seat 13 against the initial pressure of the water. It will also be noted that the interior diameter of the hollow valve body 20 is considerably greater than the diameter of said inlet aperture 12 so that when the valve body is in open position the water will exert some downward pressure on .the interior bottom face of the valve body thus tending to balance the valve and facilitating the closing movement of the same againstthe water pressure.

The upper end of the valve stem 30 is preferably screw threaded and provided with an adjustable nut or equivalent device which engages a slot or recessed portion in a lever 31- secured to the hinged seat 32 in such a manner that when the valve is in its closed position the seat will be slightly raised from the top of the bowl at its forward edge, as shown in Fig. 1 so that the depression of the seat will compress the light spring 27 and raise the valve, thus opening thewater supply inlet 12, the valve and the seat 32 being both restored to normal position by the spring 27. The lower part of the valve casing is preferably provided with a hollow extension 35 having therein a passage 36 communicating with th enlarged portion 22 of the valve casing surrounding the cylindrical valve body 20 and the extension 35 is preferably provided with two

outlet apertures

37 and 38. The outlet aperture 38 is a connected by means of a pipe 39 which extends through a spud and. stufling box of the usual construction indicated at 40, in the inlet aperture 8 of the bowl, the said pipe 39 being extended (preferably, but not necessarily) continuously, so that thedischarge end of the pipe 39 extends through the jet receiving aperture 5 of the bowl, the discharge end of thepipe or jet being indicated at 41 and being arranged to discharge longitudinally of the adjacent portion of the trap 3 below the level of the liquid seal. The aperture 37 in the extension 35 of the valve casing is preferably connected by means or a preferably internally recessed on ace and provided with packing pipe 42 with a suitable spud or connection 43 so that it discharges through the aperture '7' which maybe located at one side of the aperture 6 andwhich communicates with the rim flush passage2.

The valve casing is connected by means of a spud 45 screw collar 46 and nipple e7 with the main flushing aperture 16 of the valve casing, so as to both connect the valve casing to the rim flush passage 2 and support the valve casing with respect to the bowl. The aperture 17 f the valve casing is connected by a pipe 50 with a tank 5-1, ordinarily a able distance above the level of the valve to give the required head or pressure to the water to efl'ect a thorough flushing of the bowl after use in the manner hereinafter described, said tank being of suitable size for this purpose.

- I will now describe the operation of my be in a normal position with the seat slightly raised and the valve closed, as shown in Figs. 1 and 2. -When the seat is occupied the forward edge will be depressed thereby raising the lever 31 and lifting the valve stem and valve against the pressure of the spring. \Vater supplied by the water inlet pipe will pass upwardly through the inlet aperture 12 around the cylindrical body of the valve and a portion only of the water will pass through the aperture or apertures 23 in the cylindrical valve body and thence upwardly through the valve body to the upper part of the valve casing. The valve body when in its lowest position is below the flushing aperture 15 but when the valve is raised-the cylindrical body thereof closes said aperture as shown in Fig. 3. The incoming water which passes up through the through the aperture 17 to the pipe 50 and thence to the tank 51 in which it accumulates during the time that the seat is occupied. The remaining portion of the water admitted through the inlet aperture 12 passes through the passage 86 in the extenpasses through the pipe 42 to the rim flush discharging a quantity of water therethrough which wets the interior surfaces of the Walls of the bowl above the liquid level of the. water seal, which are normally dry. and thus tends to prevent the adhesion of is also discharged downwardly through the pipe 39 to the jet from which it is discharged through a.reduced aperture with great force. The action of this jet is twofold. First, it starts the siphonic action of the trap and discharges the water in the trap portion of the bowl, thus breaking the liquid sealand establishing a free connection with the soil pipe. Second, it disimproved apparatus assuming the parts to sion 35 and thence a portion of the same any matter thereto. A portion of the water closed tank, which is located at a considerhollow valve body therefor is delivered of air from the bowl and also discharging the comparatively small quantity of water passing to the rim aperture through pipe 42 by reason of the velocity of the jet. The effect of the jet therefore is to maintain a free passage at all times when the seat is occupiedbetwe'en the interior of the bowl and the soil pipe and to positively withdraw not only the foul air therein, but to draw in volumes of air from the surrounding atmosphere of the room in which the bowl is located and positively prevent any foul air passing from the bowl to the room. As a result of this operation of the jet, the atmosphere of the room can not possibly be con-' taminated, and as before stated, the closet becomes entirely innocuous and may be employed in any location without danger of setting up unpleasant or unsanitary conditions. As soon as the seat is relieved, the spring 27 causes the front edge thereof to rise and simultaneously reseats the valve 21 on its seat 13 and closes the water supply, thus cutting oil the supply of water to the

pipes

39 and 42 and simultaneously opening the aperture 15 which is the main flushing aperture, thus permitting the water accumulated in the tank 51 to pass with great force and volume to the rim flush, this removing any contents of the bowl which may remain, thoroughly cleansing the bowl, and trap, and as the pressure and volume of the water subsides with the gradual emptying of the tank, the last portions of the water so admitted fills up the lower portions of the trap and restores the water seal, thus preventing any foul .air or gas from passing the bowl.

In Fig. 5 I have illustrated a modification of my invention in which the valve casing is constructed exactly in the manner shown in Figs. 1 to 4 inclusive, except that the extension and the pipe connections therefrom are omitted, and therefore the ventilating feature before reterred "to is not present in this modified form of the valve. This modification of the valve further retains the otl1er.features hereinbefore described. The parts of the valve shown in Fig. 5 are lettered to correspond with the similar parts shown in the other figures, the letter a following each reference :numeral. In theop eration of this form-of the valve, when the seat is depressed, the valve is raised and the water entering through the inlet aperture 12, passes around the cylindrical valve body 20 through the apertures 23, therein, which in this case will have their combined areas substantially equal to or in excess .of the area from the soil pipe backwardly to of the aperture 12 so that all the water entering the valve casing may pass upwardly through the hollow valve body. The

water is prevented. Upon the seat bein released the valve descends by means of the spring 27* and is also assisted in closing by the pressure of water above the valve and the contents of the tank are rapidly discharged through the aperture 15' to the rim flush, thus setting up the siphonic action, breaking the liquid seal, discharging the contents of the bowl, and cleansing the bowl, and restablishing the liquid seal.

In both forms of my invention it will be seen that a light. spring 27 (or 27) will be sutficient to close the small inlet aperture 12 (0112) so that injurious strain upon the spud which supports the I valve casing and connects it to the bowl is avoided.
