CHARLES H. GUNN, OF OAKLAND7 CALIFORNIA.

COMBINED TOILET FLUSH -AND INTAKE VALVE.

Application filed July 29, 1924. Serial No.v 728,860.

To all whom. t may concern:

Be it known that I, CHARLES H. GUNN, a citizen of the United States, residing at Oakland, county of Alameda, vState of C-aliiornia, have invented certain new and useful Improvements in Combined Toilet Flush and Intake Valves; and I do declare. the following to be a full, clear, and exact description oit the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part oli this application.

This invention relates to the plumbing art and particularly to flush valves and operating apparatus therefor used in connection with toilets of all kinds.

The present, application includes improved details oi' construction over the apparatus shown in my copending application for patent, Seria-l No. 720,211, tiled June 16th, 1924, the object of the present invention being to render the valve action much morel simple` and eflicient. and also to allow the seat and seatcover to be of common construction without interfering with the operating mechanism.

A further object is to avoid the necessity of having any spring closure control for the valves which will eliminate any possibility of the same being subject to leakage.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of rei erence indicate corresponding part-s in the.

several views:

Fig. 1 is a side elevation oit the complete apparatus as installed in connection with the toilet.

Fig. 2 is a top plan view of the same.

Fig. 8 is a vertical section of the complete Fig. 4 is another vertical section oi the valve taken at right angles to the section shown in Fig. 3.

Fig. 5 is a sectional view taken on a line 5 5 of Fig. 3.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 designates the toilet which is of usual construction. and having the usual hinged seat 2;

The numeral 3 designates the pressure tank connected with the bottom of which is my improved valve ceastructon which includes the valve casing 4, having open communication at its upper end with the said tank. Hthin the casing 4 is karranged a valve housing 5 formed in the bottom or' which is the valve seat 6 surround ing port i' connnunicating from the house ingl 5 into the casing 4. An inlet pipe S leads from the source of water pressure supply, such as the city main or the like, into the housing 5.

The numeral 9 designates the centrally ported diaphragm arranged substantiall)r midway of the casing 4 and having a valve seat 10 surrounding its port 91.

The numeral 11 designates a valve stein slidable in a central guide 12 and 'extending through the central port 9a of the diaphragm 9 and through the port 7. As will be noted, the valve seats 6 and 10 are positioned in opposed relation with respect to each other. On the stem 11 adjacent the two valve seats 6 and 10 are meta- l shells 13 and 14 respectively, in which are seated valve gaskets 15 and 16 of rubber or other desired material arranged for engagement with the respective valve seats to form closures for the ports, as and for a purpose as will be presently pointed out.

The distance between the gaskets 15 and 16 is slightly greater than the distance between-the valve seats 6 and 1() so as to allow the alternate opening and closing of. the ports 7 and 9a. The valve stem 11 has'an extension 11"1 provided with a transverse slit 11b in which projects the cam 17 mounted on the arm 18 keyed to the shaft 19, which is journaled in the side of thecasing 4 and has on its outer end outside the casing` 4 thev lever 20. Y

A supporting plate 21 is bolted to the sta-- tionary part of the toilet by` cap screws 22 and supports the valve structure just described. These cap screws'are standard on all modern toilets and serve to secure the hinge structure of the seat to the bowl. This plate is provided with a pair oflugs 23 between which is pivoted a lever 24. At one end of this lever 24 is an adjustable screw 25 arranged for engagement with the lever arm 20, while the opposite end of the lever 24 projects underneath the hinged seat 2 for contact with a plate 26 secured to the said seat 2.

On the lower end of the extension 11a of the valve stem 11 is a coil spring 27. This acts to normally hold the Stem 11a down againstv the cam 1.7 which in turn forces the lever arm 20 to engage the screw 25 and press the lever 24- down at that end so that its opposite end engages the plate 26 and holds the seat 2 in slightly elevated position, as shown by dotted lines in Fig. 1. ln this position the water pressure in the housing 5 is trapped therein and holds the valvel 15 closed against its seat 6 so that no water can escape into the easing 4.

When a person sits on the seat 2 the weight moves the seat clow/'iiwaidl-y and presses the leve-r 24 to lift the arm 20, This through the medium of the shat 19, arm 18, cam 17 and extension 11a lifts the valve stem 1l and brings the valve 16 into closed position against its seat 10 and simultaneously lifts the valve 15 from its seat 6. lVater then flows through the port 7 into the tank 3 until the air pressure in the tank equalizes the same, whereupon this condition continues until the weight of the user is removed from the seat 2. As soon as this weight is removed the water pressure in the tank 3 acts against the valve 16 and. forces that valve open and closes the valve 15. Thereupon the water under pressure in the tank 3 flushes out through the port 9 and thro-ugh the open end 2S of the casing 4 and through'the flush pipe 29 into the toilet 1, there serving its usual function. lVhen this is accomplished the spring a7 has sufficient tension to hold the seat 2 partly open, as has already been described, and this device is again ready for functioning upon any further persons sitting upon the said seat.

The water pressure desired for the Vflushing .operation may be adjusted by the relative positions of the gaskets 15 and 16,

From the foregoing description it will be readily seen that I have produced such a device substantially fulfills the objects of the invention set forth herein.

lVhile this specification sets forth indetail the present and'preferred construction oic the device, still in practice such .deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim'as new and useful and desire to secure by Letters Patent is:

1. A toilet flush comprising a casing adapted at its upper and lower .ends liofr lessees@ direct connection to a tank and a toilet llush pipe respectively, a water intake pipe, a chamber in the casing to which said pipe leads, said chamber extending transversely of the casing intermediate the ends thereof and not interfering with the iree passage of water from one vend oi the casing to the other, a transverse and oriiced wall across the casing below the chamber, the latter having an orifice iny its lower side disposed in vertical alinement with said wall orifice, and valves for said ol'ces mounted in common and adapted to be moved to alternately close the orifices, the valve for the chamber orilice being inside the chamber and closing with a downward movement, whereby water pressure in said chamber will not tend to open the valve.

2;. rlhe combination with a toilet comprising a bowl, a seat hinged thereon and screws securing the hinge to the bowl; of a flush valve structure mounted in connection with the bowl, a horizontal operating arm project-ing from the structure, a lever having one end under the seat and the other end under the outer end of the arm, and means for pivoting the lever onto the bowl in connection with the seat-hinge screws.

3. The combination with a toilet comprising a bowl, a seat hinged thereon and screws securing the hinge tol thebowl; of a flush valve structure mounted in connection with the bowl, a horizontal operating arm projecting from the structure, a lever having one end under the seat and the other end under the outer end of the arm., and a plate secured on the bowl by the seat hinge screws, the lever being pivoted on the plate.

4. The combination with a toilet comprising a bowl, a seat hinged thereon and screws securing the hinge to the bowl of a -flush valve str eture mounted in connection with the bowl, a horizontal operating arm projecting lfrom the structure, a lever having one end under the seat and the other end under the outer end of the arm, and a plate onwhieh the lever is pivoted', secured to the valve structure and to the bowl by vthe seathinge screws, whereby to maintain said bowl, valve structure and lever in deinite positions relative to each other..

In testimony whereof l allix my signature.

CHARLES n. Gunn.
