IN V EN TOR. H1 u 13 eiJWt' ii/L BYQ A TTORNEY HARRY ONEILIQYOF CHICO, CALIFORNIA FLOAT-GONTROLIFED FLUSH VALVE.

Application filed'March 27, 1922 Serial No. 546,987.

To all whom it may concern:

Be it known that I, HARRY ONEILL, a

citizen of the United States,xresiding at Chico, county of Butte, State of California,

have inventedcertain new and useful Improvements 1n Float-Controlled Flush Valves; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon; which form a part of this application.

This invention relates to improvements in flushvalvessuch as are used in'connection with toilet fiushtank s, the main ob jects of my invention being to provide a flush-valve structure in which the common rubber float-ball with its trouble-giving propensities as to leakage'androt is 'elimf' inated; there is only a single valve-seat'or gasket member which any one can replace in a few seconds if necessary but which should wear for severalyears; there is but very little wear' possible; since the parts are-substantial and the number and complication thereof is reduced to a minimum; and the flush when in operation is practically noiseless, the last being by no' means' thelea'st of-the advantages of my device;

device, except for the individual type of trip-handle used, is equally adaptable forhigh andlow tanks, and whether these are'of old or new stylesi A" further object of theinvention" to produce a simple and inexpensive" dGVlC and yet one which will beexceedingly ef-' fective for the purposes for which itis' de= signed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fullyapp'ear by, a perusal of the following specification and claims.

In: the drawings, similar characters of reference indicate corresponding parts in thesevera'l views; I

Fig. 1 is a sectional}elevation'of a tank, showing my improved valve and flush "structure therein, also partly in section;

Fig. 2 "is an enlarged det'ached'view of the valve member, just after'the-trip'has been" actuated. I

Fig. 3" is'a'similarv'iew, showing the relation of the parts when the tank is, emptied.

Fig. 4 is a view of a type of handle member for use with low-set tanks, taken on the line 4.4 of Fig. 1.

Fig. 5 isa view of a trip actuating means for use with high tanks- Fig. 6 is an enlarged section ofanozzle.

Referring now more particularly to the characters ofreference on the drawings, the numeral 1' denotes a tank having a waterintake pipe 2,- and a larger pipe 8"leading to a toilet bowl, this latter pipe having a goose-neck o-r bend'etashort distance abovethe" full water-level line A, and a downward rontinuationo of said bend open on the bottom and terminating a short distance from the*bottom of the: tank.

Extending horizontally in the tank' is a bracket 6, onthe outer end ofwhichis fitted an inverted L shapedand hollow con nection"? the outer horizontal'end of which is suitably connected as bymeans-of' a union and. elbow 8 to the upper'end'of'the supply pipe 2 While the lower end is similarly connected to a pipe 9the: lower end ofuvhich closed by a valve member 12 slidably 'mounted in the fitting? and. projecting there through at the end thereof adjacent the bracket. This-valve has on its end facing the member 11 a' gasket 13 preferably of pure rubber,; and which is seated in said valve so asto be readily replaced whennecessary. Extending in alinemont with the" valve IQ andthereb'eyond, and slida'blezina groove 14' formed in the bracket dis a' trip-pin or valve releasing-f and holding; member 15, the end of whic'hopposite'to the valve 12 is pivoted onto. an arm 16which in turn is pivotedbelow the connection of" the pin 15, the upper end of said arm hav ing a' rod17extending therefrom substantially at right angles theretoand carrying on itsouter 'end'a'ba'll-float 18o-f the'usual t pes The pin orrod 15 has a luglQproject. ingup from adjacentiits'free end, to which is flexibly'connected one end ofa link"20 the upper end of which is similarly connected (if used with a low-set tank) to the end of a crank arm 21 formed on a turn-. able rod 22 mounted in the front side of the tank and having an operating handle .23 on its outer end, as shown in Fig. 1.

For a high tank, the pin-controlling link is supported at its upper end by a slotted I yoke 24: fixed on one end 'of'a horizontally with the interior of said member.

I A, "tubular 1 member 10 is adjustably 7 screwed into the member 10 so that the size of'the hole openings may be regulated as desired, thereby adjusting the force of the flow, I

In operation,suppose thetank to be as shown in Fig. 1, in which. it will be noted that the float 18 is raised, causing therpin' 15 to move along its guide in the bracket, engaging the valve 12 and forcing the latter into contact with the member 11,

thereby closing the opening therethrough' and stopping'the admission of water from the pipe 2to' the pipe 9. It the float is properly adjusted, this closure of the valve will take place when thewater level is just" i below the bend l of the flush pipe 3.

12. away from its seat member 11 and thus 7 allowing; the water in the pi'pe 2 free access: to the pipe 9, as shown'in Fig. 2.

I bend 1 into the pipe 2 when a siphoning ac-,' tion is at once set up, .the startfoi this action being speeded up byreason ofthe intake pipe 9 discharging directly into the 7 pipe 5, causingthe tank to be rapidly drainedand'the float 18 to be lowered, until the water is at the lower end of therpipe extension 5', which allows air to enter the j Now if it is desired to flush the toiletpthe link 20 or 20 is raised by manipulation of the handle 23 or lever'25 respectively. This will cause the pin 15 toibe raised at itsend f 'adjacentthe valve .12 to a point above the latter suficient to permit the 1 water pressure constantly inthe pipe 2 to force theivalve Thewater level in the pipe. extension "5 is then raised until it overflows through the same and terminates the siphoning action while levingplenty of water in the toilet V bowl for a seal.

Owing to the 'fact that the extension 5 V is very nearly, full before the tripping or fiushing action is started, so tha'tthe operation is practically noiseless, and the objectionable roar had with the ordinary flushtank practically eliminated- It will also be noted that the need and use of a rubberball to close the outlet is done away with, r

so that if the gasket 13 makes a good sealwith the seat ll'no leakage of water is possible. a V i 7 7 "Now when the float 18 is lowered with the lowering of the water the pin 15 gradually moves to the rear of the valve 12' and finally 'drops behind the same onto its grooved seat 14: and in alineinent with the "valve (see Fig. 3 ii-r position toonce more engage'and force the same toward its seat 11 as the water level is gradually raised by the incoming water.

I V- I i Having thus described my invention,-

what I claim as new and useful and desire to secure by Letters Patent, is v 1. A flush system for toilet tanks and the like comprising a water intake pipe passing into. the tank; an outlet pipe therefrom, a: valve member for closing the intake pipe, slidably. mounted with respect thereto and:

projecting outside the. same, an independent pin in normal alinernent with the valve member and adapted to engage the enter end thereof, float controlled means for mov- 3 mg the pintowardthevalve as the tank is v filling and to which the opposite; end of the pin is pivoted, and hand actuated means for s raising the end, of-the pin nearest the-valve out of'engagernent with the latter whereby the valve is freeto move outwardly of the 7 intake pipe, the I water pressure in said acting to forceit in that'di'rection. 1

7 2. Inayfiush system for tanks, an"intake pipe extending intothetank, anroutlet pipe leading therefrom and terminating in the tank in a downwardly directed andopen' end," a nozzle on the intake pipe projecting up into the opennend of said outlet bend, 'Sflld nozzle having a plurality of upwardly directed orifices, and means for altering the sizes of all said orifices n common,
