, CLEVELAND, OHIO. v 1 i FLUSHING-TANK.

To all whom it may concern:-

Be it known that I, FRANKSoHm-ER, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in F lushing-Tanks, of which the following is a specification.

'My invention relates to an improvement I ber bulbs more commonly used.

In the accompanying drawings, Figure l is a side elevation and vertical section of the flushing tank embodying my invention, and Fig. 2 is a plan view and horizontal section of Fig. 1.

The tank 2 may be of any suitable construction adapted to hold a predetermined amount of water, the level or height of which is fixed by a valve 3 and float 4. V This valve is mounted to slide upon the upper end of'a supply pipe 5 which extends upwardly into the bottom of the tank, and the float 4: is pivotally mounted at the upper end of a screw-threaded stem 6 carried by a lug 7 on the supply pipe. Adjustment of the screw stem to raise or lower the pivot for the float determines the level of the water in the tank, and this level is fixed at a slight distance below the bend 8 in an inverted U-shaped siphon member 9 having a flexible or bendable portion 10, shown in Fig. 1 as a separate rubber tube or pipe reinforced or strengthened internally by a coiled spring 11. The intake end 12 of this siphon mem- 'ber may be of metal with its extremity 13 bent to project substantially parallel with the vertical extension of the outlet pipe 14 which is secured to or made integral. with an outlet fitting or member 15 fastened by a nut 16 at the bottom of the tank. The intake and bendable portions of the siphon member are preferably inclined or set at an angle to promote an instant flow and complete submersion of the upper bend 8'upon imparting a pull or push thereto through the r medium of an operating device of any suitable character. As shown, a lever 18 is used Specification of Letters Patent.

which is operatedby a handle 19 placed upon theoutside of the tank and when-the siphon member is flexed and carried beneath the level of the water, a flow of water is established through the siphon .member and the tank siphoned of its contents. As soon, as the water level drops to the open extremity l3 and air is admitted the siphoningaction is broken and cannot be again established unless water is again admitted into the tank and maintained at the original higher level.

Admission of water into the tankis automatically controlled by valve 3 and float' l. Thus, when the float drops valve 3 israi'sed sufiiciently from the upper end of supply pipe 5 to admit water into the tank through the lateral passage 20 and a downwardlyextending pipe 21, and the inflow of water into the tank will continue until the float l rises and sets valve 3 solidly against the upper 'end of supply pipe 5.

PatentedliIa1'..3(),1920. Application filed January 29,1919; Serial No, 273,853. i i I I A by-pass pipe 22 is also provided to deliver water from the supply pipe 3 directly to a branch stand-pipe '23 which connects with the outlet fitting 15 for the tank, but the flow through this by-pass 2 is shut oif when the tank isfull and valve 3 is seated and closed. Thepurpose of this auxiliary flow of water to the outlet for the tank is to supply the closet bowl with suiiicient water to fill the bowl to a predetermined level after flushing operations. i

What I claim is:

1 In flushing tanks, a tank and an outlet fitting extending into the tank and .bent. laterally at its inner end, a flexible tube affixed to said fitting and projected in con-. tlnuatlon of the bend therein, a coiled wire spring engaged with the walls of saidtube and adaptedto sustain the same in normal posltion, a siphon tube having a U-shaped extremity secured to the upper end of said flexible tube and provided with a straight body portion lying relatively over the back of said flexible'tube and parallel therewith and having its intake end bent inwardly toward the said outlet fitting and the mouth thereof relatively near'the bottomf-of' the tank, and means to bring said tubes into siphon starting position. i

2. In flushing tanks, a rlgidfitting'in the p bottom of the tank having a laterally curved end, a straight rubber tube secured to said end and a sustaining spring coil therewith,'

a siphoning tube having one end bent to U-shape and fixed upon said rubber tube and said siphoning tube havinga straight body disposed lengthwise over and next to the said rubber tube and having'its lower end partially overlapping said rubber tube and bent inward arallel' thereto.

3. In fluslung tanks, a tank having a tubular fitting set upright in the bottom thereof nd havi g its inner end turned to an inclined position, a straight flexible tube pro jecting in prolongation of said bent end and secured thereto and a coiled ire spring in said flexible tube adapted tosustainthe tube in working position, a siphoning tube having 3 2 urshaped end fixed on said flexible tube; and having its body inclined and its intake; end bent toward said fitting, and means to? actuate said tubes and cause them tosiplion. l20 Y Signed Cleveland, in the county of Cuyahoga, and State of Ohio, this 8th day of January, 1919:. s V
