FLu's'HlNG-y/ALVE.

l Application led Hersh 25, 1895.

-To all whom/t may concern.- I 1 i'. 'Be 'it-known that I, EDWARD L. POWELL, a citizen of the United States, and a resident of Atlantic Highlands, county ot' Monmouth,

5 and State of New Jersey, have invented'eertain new'and useful Improvements in Flushing-Valvesbf which the followingy is a speciiicatiou, reference being had-tothe accompa- 'nylug drawings, forming a part thereof, in-

Whieh similargures of reference indicate eorresponding,r parts in all the views. l This invention relates to .flushing-tanksto be operatedin connection with water-closet basins,urinals, &c.; and the objectthereof is to, provide l'an .improved valve vmechanism for such tanks, which shall be simple in construetion andA effective in operation: a; l

which is comparatively inexpensive.

Avfurther object of my invention is to pre Vent the objectionable noise due to pounding,

which occurs in 'the usual automatic valve mechanism.

The nvention is'fully disclosed'in the fol-4 lowing' specification of which the accompanying drawings form a-part, in which-'- Figurel represents a central vertical section of apank provided with my improvement, and Fig. 2 a section on the line .r .r ot' Fig. 1,' lookingdownwardly. f

Referring to- Fig. 1 ot' the drawings, the

numeral 2 designates a flushing-tank ot' any suitable form, material and capacity, and 3 a water-supply pipeV for the same, the iowy of .Water therethrough being regulated as usual by an ordinary valve 4, with which is'eonnected a lever 5, provided with-'a float 6.

' .Secured in the bottoni of .the tank in any desired manneris a' pipe-7, the inneren'd". or

a hollow -ball-valve 8, which is preferably composed of rubber or some simlarliexib? e v material. This valveis prei n'a'my located,

in FigLl, the top of said-tube being In'eferl ablyfiuclined downwardlyand said plate restmg ,upon said inclined surface;l the upright rods 411,'the. lower ends of which are'secnr'ed lng secured toa hollow eylinder'12, lthe bot torn of which is open -and the' top of which is weight of the water therein.

opening of whichis designed to be closed by tovsaid plate and the upper .ends thereof be-1 serai No. 555,017. mmam:

closed and provided with a. loop or other attaching device 13, with-which 'is connected one'end of a chain, the other end thereof being connected with a lever. 121.- 'lhis cylinder is preferablyv composed of'thin sheet metal onf 1 similarmaterial, and it is 'not essential that all Y the'rods'llfbe connected with.v said cylinder,

but only asuicientn'umber thereof to' form' guidesfor the valve and to supportsaid eylf- Connected withthe upper end of the inder.

pipe 7 within the tank 2 and-below the opensmallpipo' 16, .the outer end of which is curved upward and communicates with atube -ing of said'tube and thevalve thereon is'a 'per end with a narrow slot 18; through which said pipes 1G and 17 and the slot 18 air enters `the pipe 7 beneath the 'ball,-tl1ereby lclearing thel full pipe below the valve of the This pipe must necessarily be full of water when the valve closes, and the weight of said water'is'such' as' to force the ball down lso heavily as to cause it to rebound, resulting vin a constant hammering. v shown is designed to .prevent whistling of the air as it rushes down the tube,

rlhelower end of the pipe 7 is provided with a screw-.thread on its outer surface, as shown, by which said pipe is-adopted to be connected with an ordinary waste-pipein the' usual manner, and the operation of the apparatus is sub-'- The particular form'of air-tube stantially as'follows: X-Vhen there is no water'` its seat inthe plate 7, andwhen the air rises retain the-ball in this position.

j'and'when itis .eleasedthe Valve isfusually seated and the flow cut oi. In my apparatus the valve 8 will not be reseated as-soon as the freq-f h A lever is released, unless said lever is lheld long enough to permit of the ,discharge of the contents ofthe tank down to or approximately to the top of the pipe 7, at ,which tiniethe ,5 valve will be reseated andlthe further. flowv of water through saidpipe prevented until' th-lever 14 iis-again operated,.as before desigrjibed, :when theoperationof :theyal'xwas set out, will'be again repeated.

The4 object of closing the upper end o'f the cylinder 12 is inA order th'atit. may f orm an airlchamber and thus, should the valve for any reason fail to act,. the said cylinder, and

iltherewith the frame and ball 8, will be buoyedA x5 by the water rising in the tank, so' that the discharge-tube will be openedto allow egress'v of the water,l and willthus prevent ove r-o'w l .of the tank.

scribed, as it is evident-.that many changes therein may be mb-fle wif-bou., departing'from .""the scope of invention; but," Having fully described vsaid invention, itsl b5," construction, and operation, what I desireto 'secure by Letters Batent'i's- 11A dev'ioeof the classdescribed, compris-- i nga tank provided with an automatically op'7 '.erated water supply, a discharge pipe, are- 'discharge 'p pe when vthe frauie. ifs-lowered 3o @movable frame adjacent the pipe, ajvalve a a. ,I

The combination, with a flushing tank having an automatically controlled water supply, of a discharge pipe located in the bottom thereof, a hollow elastic ball adapted to close the mouth of said tube, a fra'me withv 4 in which said valve is located and bywhich l do notI coniine myself to the exact form zo and oonstruction'of the parts shown yand deit is o rated, consisting ,o`f an annular bot- -tolnp ate'adapted to. surroundthe opening in. the inner end ofjthe pipe, wei-tical rods connected with said annular plate and extend'- ing upwaldand connected with the hollow cylinder, and the lower end Tof which is open and the upper end of whiclris closed, and connected with an operating lever, and a pipe communicating' with the discharge pipe 'oelow the Valve seat and with a tube` or-pipe extending upwardly through the'tank, the
