Speccation of Letters Patent.

Patented Mar. 25, 1919.

Application filed September 10, 1917. Serial No. 190,688.

T0 all whom t may concern:

Be it known that I, Jol-IN N. MURPHY, a citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented new and useful Improvements in Siphon Flush- Tanks, of which the following is a specification. y

My invention relates to improvements in siphon flush tanks.

The purposes of the invention are to provide a flush tank having a siphon structure integral with the body of the tank, and to provide means for controlling the flow of water through the siphon structure to induce siphon action to cause the water in the tank to be discharged through the siphon structure. The invention is illustrated in the anneXed drawings, to` which reference is hereby made and will now be fully described and the novel features thereof will be recited in the claims.

Figure 1 is a longitudinal sectional view of a flush tank and the siphon structure embodying my invention, taken on the line 1. 1. of Fig. 2. Fig. 2 is a top plan of the flush tank and accessories; and Fig. 3 is an enlarged vertical section on the line 3. 3. of Fig. 2. The ball cock is omit-ted ,from this view.

The same reference numerals designate the same parts in all the views.

The tank body 1 is preferably of cast metal. The tank-bottom 10 is preferably flat as shown. rThe end walls Ll1 and the side walls 42 are preferably erect relative to the bottom, as shown. rIhe siphon structure is integral with the tank body and comprises a vertical member 2 and an unobstructed horizontal member 4. A vertical partition 3 divides the vertical member of the siphon structure into a water chamber 35 receiving water from the tank through the inlet opening 10 and an air chamber 36 in unobstructed communication with the interior of the horizontal member 4L of the siphon structure, said member 4 being adapted to eect free and unobstructed discharge of water through the nipple 6.

The preferred accessories used in conjunction with the siphon-structure will now be described.

The flanged nipple 6 occupies the opening 5 in the bottom of the tank; a packing ring 7 and a stuilingsbox ring 8 surround the nipple and are adapted to enter the opening 5. A nut 9 screws onto the nipple and upon tightening the nut, the ring 8 will ress the packing 7 into the opening 5 to mi :e water tight connection of the nipple with the tank.

, A water-connection nipple 12 at the lower end of the main supply pipe 11 extends through the bottom of the tank and has dircct communication with the source of water supply and with the interior of the supply pipe. The supply pipe has a lateral member 13, Fig. 3. The body 11 of the self-closing faucet screws into the member 13. The intake pipe 29, (Fig. 1), screws into an elbow 28 on the supply pipe 11 and delivers water under pressure from the supply pipe into the tank when the ball-cock 30 is open.

A ball-cock 30, of usual construction, communicates with the interior of the supply pipe through the opening 27 (Fig. 3). The means for operating the ball-cock 30 comprises a lever 32 (Fig. 1), having a link connection with the handle of the ball-cock, a float 31 floatable on the water in the tank and a rod 33 connecting the ioat with the lever 32.

A valve-seat member 15 having a circular flange 16 is located in the outer end of the member 13, and the inner end of the faucetbody bears against the flange 16 to hold the part 15 firmly in place. The outlet member 25 (Figs. 1 and 3), of the self-clos ing faucet communicates with the chamber 36 of the siphon-structure through the opening 26 in the top of the siphon structure in line with the air chamber 36. Packing 37 surrounds the member 25 and prevents leakage at the juncture of the cock with the siphon structure.

A block 20 (Fig. 3), extends through the wall of the tank andscrews into the body 11 and has at its outer end wedge-shape members 38. A valve rod 17 within the faucet-body extends outwardly through the block 20 and through the hub of the lever 21 and has at its inner end a plug 19 adapted to seat on the member 15. A spring 18 surrounds the valve rod and normally acts to hold the plug 19 against the seatmember 15. The hub of the operating-lever 21 has wedge-shape members 39 which engage the members 38 of the block 2O to cause the valve rod to slide outwardly in the block 21. A screw 24 screws into the end of the valve-rod and 'connects together'the parts 17, 2l and 23. Packing 34 in the block 20' surrounds the stem 17 and prevents leakf, age around the stem.

Operation.

In practice the supply pipe VWithin the'r Hush tank, being connectedA With the source of Water supply asis usual, and theballcockt 30 ybeing open, Waterunder pressurev Will `flow through.. thesupply pipe- 11.*and theintake-pipe29 into the tank and thence through the` opening.. 10 into the Waterchamber 35 ofthe` Siphon-structure, until the Water `in thetankand in the chamber 35 reaches` the level of'theupperfend of the verticalpartition 3'; and thereupon the iioat.y

31, floating in the'vvater in the tank, Will cause-the rod 33 hto operate the lever-,32 and connectionsf to closethe ballcock30, to-v stop the loWof the Water.- To dischargefthe Water from thetankthelever 21 will bef-- operated.. by hand` to open thevalve 19--to permit Waterlfromv the supply pipe 1l to How-through vthe/...outlet 25 into the chamber 36 to expel` air vfrom the chamber 'and thereby. induce vSiphonY action to discharge thecontents oit-the tank throughy the outletl 6. When a suiiicient quantity of Water has been-Withdrawnfrom the tank,l the valve 19 Will close automatically v.to stop 'the outward iiovvl lof `vvater. through the Siphon-structure and :permit the :Water from the supply ,pipe-y to ow throughthepipe 29 into the tank lto refill the tank; and so on as often as it may partingirom thefbroadispirit of my inven-y be desired-,to usethe Water .in the-ftankand refill. the tank.
