Patented Sept. 17, 1929 UNITED STATES JESSE C. OWENS, OF LOS ANGELES, CALIFORNIA TOILET-TANK FLUSH VALVE Application filed April 26,

construction of the existing forms of flush- 1 ing valves; to provide a valve of the character referred to that may be easily and inexpensively manufactured and installed; to provide a construction wherein the pressure of the water from the source of supply, for instance the city water mains, is utilized for compressing air that is effective, when the valve is manually opened, in adding forceto the flushing waterthat discharges through the valve; further, to provide in a flush valve, a float that is utilized for normally closing the outlet from the valve; and further, to provide a flush valve that is strong and substantial in construction and having comparatively few operating parts, therebyminimizing the liability of the valve becoming inoperative and ineffective due to disarrangement of the parts.

Further objects of'my invention are, to provide a toilet tank flush valve that is practically silent in operation during the flushing action and during the refilling of the tank, further, to provide a device of the character referred to that is economic in the use of water and which is non-leaking when prop erly installed, and further, to provide a simple and efficient means including ducts and check valves for permitting air to enter the tank and valve to permit the water under pressure to readily discharge from the tank and pass thru the valve to effect the flushing action.

My present invention is an improvement on the pressure flushing device disclosed in U. S. Letters Patent No. 1,566,769, issued to me December 22, 1925, and also my co-pending application for U. S. Letters Patent, filed July 16, 1926, Serial No. 122,815.

With the foregoing and other objects in 1928. Serial no. 273,120.

'view', my invention consists in certain novel features of construction and arrangement of parts that will hereinafter be more fully described and claimed and illustrated in the accompanying drawings, in which 1 is a verticalsectiontaken thru the central portion of a tank and showing my lmproved flush valve associated therewith.-

r Fig. 2 is a front elevational view of the valve with the upper portion thereof in vertical section.

Fig. 3is an enlarged vertical section taken 'on'the line 3-3 of Fig.1..

Fig. 4 is a verticalsection taken lengthwise thru the center of the valve and showing the same in open or flushing position. v

Fig. 5 is .a. horizontal section taken on the line 55 of Fig. 4.

Fig. 6 is an. elevational view of a tank and bowl and showing my improved flush valve associated therewith.

' Referring by numerals to the accompanying drawings which illustrate a practical embodiment of myinvention, 1O designates a tank that is adapted tocontain a substantial volume of flushing water, said tank being of air-tight construction and receiving its supply of water from a pipe 11 that is connected to a suitable source of supply,'for instance, the city mains, said supply pipe 11 leading to the bottom of the tank 10 and being connected in any suitable manner, to one leg of an inverted U-shaped pipe 12 that is positioned in the lower portion of tank 10 with its open end terminating near the bottom of said tank.

My improved flush valve includes a substantially L-shaped casting, the upright portion 13 of which occupies a position a short distance in front of the lower portion of tank 10, and projecting from the lower portion of the upright member 13, toward the tank 10, is a horizontally disposed, tubular member '1& that is connected by a suitable coupling 15, and short tube or nipple 16 to the lower front portion of tank 10.

The lower portion of upright member 13 of the valve is provided with a substantially cylindrical float chamber 17 and removably seated in the upper portion of this chamber is a ring 18 on the upper surface of which is formed a rib 19 that functions as a valve seat. The chamber 20 above ring 18 func-, tions as a valve chamber, and arranged to move vertically therein, is a disc valve 21 to the underside of which secured, in any suitable iaaaaerga ui sc sa or-taster; leather or composition, and whicli is adaptedjto' rest directly on the valve seat 19.

The top of valve clla'mbtir -2d is uetmty a screw cap 23 that is removably. positioned on the upper portion of thevalvebo'dy13,

and formed thru the centeryoflsaidecap is an opening that is provided with a gland 24 1311111 whichoperates anraxi-al-ly di-sposed stem 25;- that *proj ects upwardly from valve 21-.

Under normal 4 conditions,-'- water that enter's thr-u' suppllynpip'e 11 and the geoseneek 12, rises in tanlrlqto a-leveli wh'ere it'en- Thelowerend {of thetubularportion 51 gagesifcheckfivalve 61- andi'orces the-jsame 1 onto its seat, thereby closing the air passage thru tube 59, ducts 56, 57 and 58, and the water within the tank'under pressure, compresses, to a certain degree, air that is trapped inithe upper portionof the tank above the level of the water.

engaged and swung into a substantially up right position, thereby permitting valve 21 to rise as a result of pressure of the water against its underface, and as the valve is thus lifted from its seat, the pressure of the water trapped in tank 10 and the valve housing, will be lowered so' as to permit float 38 to rise in float chamber 17, thereby opening the upper end of outlet 33, which permits water from tank 10 and in the connection 16 and 14, to flow downwardly thru outlet 33, which flow is greatly accelerated by the pressure, of the air trapped in tank 10 above the body of water therein.

Any water that passes upwardly thru ring 18 into valve chamber 20 will, in due time, discharge, downwardly thru duct 47,

intooutlet 33. As float 38 is, elevated in its chamber, the force of water passing downwardly thru outlet 33 will bear against the upper face of inclined plate 46-so as to move the same downwardly and rearwardly, thereby swinging the upper end of arm 43 so that the head 44 thereon engages in groove 41 in the bushing 40, and thus the float is maintainedin elevated position while the water from tank 10 is discharging thru the valve and the outlet 33.

After the water has discharged thru the valve, as just described, the weight of the float.38 will effect a disengagement of the head 44 from the groove 41, and the float will move downwardly until the packing disc 39 is positioned on seat 37.

After pressure on the handle 31 is releaed, spring 32 will rotate shaft 29 so as to cause cam 30 to engage and move stern 25fdownwardly, thereby reseating the packing mem the seat 19. v j

If, when valve 21 is actuated to effect the flushing operation, as just described, there should be anywater forced past check valve 61- and thru pipe 59 and duct. 60, said water willstrike float check valve 54, and force the same upwardly against its seat on, the lower end of tubular member '51, thereby preventconnected to said inlet opening,

ing said water from passing outwardly thru air inlet duct 53, and thus any water passing thru tube 59 and duct56 will be caused to pass out thru ducts 57 and 58 that lead to the outlet 33. I

-When the valve is actuated, as just described, and the level of the body of water lowers within tank 10, a short distance, valve 61 will leave its seat, thereby permitting air to-enter duct 53 and pass downwardly thru duct 49, thence thru duct 56, and tube 59, so

as to break the seal in the upper portion of tank 10. and consequently, permitting the water to freely and quickly discharge there- "from.

In some instances, it may be found advantageous and desirable to utilize in the place of the tank 10, a vertically disposed pipe or likecontainer that is arranged in the wall to the rear of the bowl with which my improved flush valve is associated.

Thus, it will be seen that I have provided a toilet tank flush valve that is relatively simple in construction, inexpensive of manufacture, capable of being readily assembled and installed, and which valve is especially effective, due to' the fact that air that is trappedinthe upper portion of the water storage tank is 'utilized for accelerating the flushing operation when the valve is opened.

It will be understood that minor changes in the size, form and construction of the various parts of my improved toilet tank flush valve may be made and substituted for those herein shown anddescribed without depart ing from the spirit of my invention, the

scope of which is set forth in the appended claims. 0
