WATER- SUPPLY FonFLUsH-TANKS,

To all 'whom it may concern:

Be it known that I, Hanni' J. Gnt'nINn, a citizen of the United States of America, residing at Cleveland, iu 'the county of (hlyahoga and State oi Ohio, have invented certain new and useful ln'iprovcments .in `lVater-Supply Valves for Flush-flanks; and I hereby declare thc following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains tomake and use the Same..

This invention relates to water supply valves for flush tanks and particularly tothe construction of the valve and valve chamber, the construction of the operating mechanism and to the means for connecting the valve and itsoperating mechanism toI the supply Pirel One of the objects of the present invention is the provision of a' valve in w'fhich the usual hissing sound due to the"passa ge ofv water through the valve opening particular-ly asthe valve is being seated is entirely eliminated. 4

i. A further object. is the provision of novel means for coupling:r the Valve `chamber to a -pipe connection usually provided in. the bottom of-a tank in a manner such thatthc valve chamber can be quickly placed in posil tion and can be readily removed together with all 'the operating mechanism.

A still further object is the provision of a valvel having a construction 'such that all the parts may be readily removed for cleaning or repairing. i l` A still further object is theA provisionz of agnovel valve operating mechanism which is compact and will cause a"consideral `le pres- Sure tol'be transmitted to the valve plunger with ya'comparatively short armor lever to which thfioat is attached, said lever having means whereby the normal height of the oatmay be readily adjusted. l

With theee ends in View and tio-the end of realizing-other advantages hereinafter appearing, 'I'ny invention consist; in certain 'novel details oyf'constructio'n and combina,-

i ing thc joint or connection between two' parts of the lever carrying the tloat.

Referring now to the figures of the drawing, lO represents a pipe c nr1ectionconsisting of a lower tubular men'iber 1l, thc lowe'r cud of which is threaded so that it may bc readily attached to a water ailpply pipe and having a flange l2 adapted to he drawn down tightly against the bottom of a tank, and of a second tubular member 13- which is screwed into theupper end of the njiemher ll and which has a centrally located inlet opening 14 and at its upper end an out-- wardly extending flange l5. Swiveled on the upper end of this member 13 is a coupler lt having an inwardly extending flange 17 which tits loosely between the upper end of v the tubular niember.1l and the'outwardly extending Vflange 15 of the tubular member 13. The purpose'ot this coupler is to secure in place the' valve scat, valve` chamber or casing, and all the mechanism carried therfby. 'This coupler is provided with a pair of outwardly extendingr handles 18 and is `tlneaded on the interior. .`"`\At 1f) is shown a valve chamber or casinar which is somewhatcylindrical in shape and is pro'vided at its lower end with a threaded portion which iseugan'ed by the threaded 'portion of the coupler 16 and is drawn downward with its lower end in firm engagement with a gasket 2() seated on the' upper end of the member 13, by simply rotating the coupler. l

The valve chamber 19 is provided a short dietancer above' iteI lower end with an internal flange 2l and with a centrally located openingl 22 through which projects a" tubulowcr end 'below lthe internal flange-2l -of the chamber, with an outwardlyprojecting flange 2l of a'sflze such that It cnn'ages'the chamber below Athe| llangrc 2l and occupies thc-space in th'e lower end otA thecham'ber below the Mange/2l. It will bcsecn that 'at the same time that. the chamber is drawn downward .against -lhc casket 20. the lower end of the valie Seat 2V is likewise tirmly seated upon the Quake( 2U h v the engagement i ot` thc interna-l tlann'c 2l ol' thel chamber with the outwardl)` projcctiii'gr tlaurefil 'on the .xtcrnal"diameter of the valve seat 2.1 so' lar valve seat 28 which is provid-ed atfit's` cylim'lrical wall of the lower portion' of thc i that there is an annular space between the .opening for the water.

y wall of the passageway .36 is ulcrumed on agthumb screw 39 at the chamber wall and the valve seat for the en- 1 tire distance that it extends above'the iriternal flange 21. The purpose of. this will l be referred to later. The valve chamber is provided at the top with an opening* or passageway 25 directly above and in line With the valve seat 23 and the opening or passageway therein, and is provided on the side opposite the upper end of the valve seat 23 with a boss 26 having an opening or passageway 27 which forms the outlet: i This passageway 27 1s threaded on the interior so that, if desired, itmay be provided with a short outlet pipe. l 'l Located in the passageway 25 at thetop of the chamber and having a close but working tit therein is a valve stem or plunger 28 provided at its lower end with a valve seat 29 which is recessed on its lower side and carries a gasket 30 which is adapted to en gage the upper end of the valve seat- 23. The plunger is provided between its ends with a packing ring` 31, the outer surface of which engages closely the inner cylindrical 25, and the plunger has its upper end 32 projecting above the valve chamber, this portion of the plunger being reduced in diameter and having anv elongated slot 32 indicated by the dotted line in Fig` l.

`Projccting upwardly from the top of the chamber on one side of the valve plunger 28 is an arm or bracket 33 which is bifurcated or slotted-at its upper end, and projecting from thetop of the chamber on the opposite side of' the plunger isfa second bracket or arm V3?): longer than the bracket 33 and being likewise bifurcated or slotted, The valve is operated by a float 35 and'two` levers 3G and 3T, the latter being fulcrumed upon a thumb sfcrew. 38 between the portion of the bifurcated end' of the bracket 33and projecting; through the slotted upper end of the plunger and between the two arms orv bifurcations' ffthe bracket 34. The lever upper end, ot the bracket 34: and is connected to lever 37 by a link 40. y

In order that the height of the float 35 and consequently the quantity of water which is retained in the tank may be readily varied the lever 3G is formed of two parts 36P1 and 36,", the latter being at the outer end of the lever "and, having secured thereto -b a thumb nut Zl1 a stem 42 to which vthe float 35 is attached.` These two portions 3G and 36b of the lever have enlarged flat ends the adjacent 'faces of which are toothed or serrated, and the .serrated facesl being held in engagement with each otherV by a trans-- verse screw 45. .I t will bev seen from the above describl construction that all the Working parts of the Valve can be quickly attached to the pipe connection which is adapted to extend through the bottom of the tank, by simply turning the coupler 16, and that, when the working parts are disconnected the coupler is so mounted on the upper end ot the pipe connection that it cannot become separated from the same. Nibt only are all the work4 ing,r parts readily connected or disconnected by the coupler, but when thevvalve chamber is removed, the construction and vmanner of securing the valve seat permits the same to be readily removed and separated from the other parts without the use of any tools, since the `lower end thereof engages loosely the open lower end of the chamber.

As the tubular seat projects Yupward for considerable distance into the chamber and is spaced from the surrounding'wall of the chamber, the unpleasant hissing sound due to the passage of water through the valve particularly as the movable valve member is being seated, is practically eliminated for the reason that the sound is deadened by the wall of the chamber and by the water which iills the same and'for the reason that the pressure of the stream is' greatly reduced bythe latter.

By loosening' the thumb nuts 38 and 39 the operating mechanismv including the levers 36 and 37 'and the loat`35 can be removed, and the valve plunger 28 can then be withdrawn from the chamber for the purpose of cleaning or repairing. By loosening the screw '15 and adjusting the positionof the portion 36b of the lever 36 with respect to the portion the height of the float is adjusted quie y and easily. I do not desire tobe confined to the exact details lshown but aim in my claims to cover all modifications which do not involve a de .parture from v'the spirit and scope of my lnvention.
