To all whom i'may concern:

Be it known that I, CHARLES A. WULr,

l a citizen or the United States,'residing at Indiana olis, in the county of Marion and 4State o Indiana7 liaveinvented certain new vand useful Improvements in Flushing-- Valves, of which the following isa speci- The object of my invention is to supply. A

ficatio produce a lushing'valve, especially adapted for use in connection with waterclosets, in which there is a total absence of the ordinary eontrolling floats and in which the. closing of the valve willbe controlled by the pressure ofy outflowing water from the flushing The accompanying invention. l Figure 1 is a central vertical section; Fig. 2 a raginentary similar section of a modilied form; lFig. 3 a detail of the structure drawings illustrate my shown in Fig. 1, showin lthe osition of the parts when vthe initial va ve is first opened and Fig. la similar detail showing .the positions of the pai-ts during free out-- flow from the {iushing supply;

inthe fore thereof is a s ider25 upon the 26 which serves to hold in place a pac ing .ring or valve 27 which seats upon an an nularvalve seat-28 formed at the upper end Patented Auge, 191e; v

of valve 22 around the bore thereof. Spider.

25, near its lower end, is provided with shoulders 29 adapted to engage shoulders 31 formed on the valve 22 and thus limit the movement 'of the valve relative to seat 28. vIn order to move the two valve members' upwardly away from their. seats against the pressure 'of `water within tank 10, I journalf,l

which projects into the casing and Vis pro in casing 18, a shaft 33, the inner end'V of f videdwith a crank arm 34 cai'iiying a wristf pin 35 which projects into a slot 36 formed Y in the lw'er end of a 'link 37, the up er end of which is connected to spider 25. ecured to the outer'end of shaft 33 is an `operating handle or lever. 38 which has sufficient weight to pull the valves down upon their seats. Shaft33-lias its axis arranged to one side ofthe axis of the valves fora purpose -whichlwill appear.

The operation is as follws:-Witli the parts in the position shown in Fig. 1, water introduced into tank l() through pipe 13, will act upon the upper faces kof ythe two valve members to hold them totheirseats 19 and 28, forming an air cushion 'iii the upper end of the-tank. yWhen lever 38 is raised the valve 2G-27 will first be witlh4 'drawn from its seat 28 andthis maybe dona-"l" with comparative ease because the .valve is' comparatively small, the parts coming into the osition shown in Fig. 3. y'l.`l1ewater will egin to fiow through the bore of the valvemember 22 whereupon further up ide crank `pin v35lias been carried beyondlthe axis-of the valve so that the pressureof the flowing Water upon the uplper faces of the a ,ves will serve to ho dy lever 38 from L downward movement and thus the valves Willbe held open. The weight of .lever 38 is just'enough to bring the valves to closed position'when there is about eight cauces du .ahalf' pound, (more or less dependmg'u on opressure uponltheupper of .the valves and. consequently, as ,soon asthe out-v iovsfafrom tanl: L1() has been vsuliicient-'to' re? i the pressure ,-thereinl 'to approximately the'weight ci lever 38 tending to' pr uce return movement of shaft 33) the said lever iviilserveto automatically return the valves to clawed position and thus cut od the Hushe'lewv; .Y v

Actual practicehas `deino'lwtrated that the valvey meehanism operates with certainty Aaa fing crippling and. .iniii:orrnity It will be seeny that, by

closing the supply valve 51,' which is in the Ifeed line leading to ,pip`e 13, and disconnectmay be rea ilywithdrawn for the removal `of sediment and for the replacement of the' pacltin rings 23 and 27. A

in t e 4form shown in Figs. 1, 3- and 4, there is a eontinuous inflow of ywater from the su ply .pipe 13 during the lushingactionportion of the .iiushing iiow. In thestructure shown Ain Fig. 2 all of the parts are identical with the parts similarly ldesig usted .in Fig. l, but uard 14 is omitted.

- in 'this forni the supp y pine 13 is closed at its inner end and communicates with the. l interior of the tube 12 by. means of two axially alined openings 52 and 53 into which a pin 54 carried-by cap 26, isprojected during the time the valves arein olen position, as clearly shown in Fig. 2. he pin 54: does not need to lit openings 52 and 53 very vtightly but, byu'en'tering said openings,- the l iniow' of water `from pipe 13 during the Y readily unilied without in any manner.

time the valves are in open position, is.

practically stopped. v

It is to boeunderstood that, while have, shown the-valve members as being -composite in order to facilitate the openingthereof against accumulated pressure, yet

my inventionis by no means limited to such'.

a construction, for it is readily apparent that the two nested valve members mightfbe changing the operation of the device other than increasing the amount ofi force necesv sarA to get an `initial opening thereof.

n thev normaloperation'ofbrny device itA is entirely probable that the 'velocity of out,- ow from the apparatus to the bowl will decrease, as the amount of water and pressure in the tank decreases., to a suilicient extent to lgradually diminisli'the fiow from the bowl 17the entire valve mechanism` n the modification shown in Fig. 2l this inotv is prevented during the major' `ating member, and a cra tween said operating member'and' the valve,

v'pending' upon the p ythe 'purpose set forth. A

adapted to engage the valve 22 and vserve to hold the same open until a suilcient pressre has accumulated above the valve. The

vspring 42 will serve to hold the, acking ring 23 when a` 4short distance above t e valve seat 19, this distance being less than enough to.,

accommodate the full flow entering tube 12 from pipe 13, so that whenever the' valve is brought down upon the spring, there 'will inevitablybe a gradual vaccumulation of ressure on top of the valve ,so as to insure its ultimate closing, although there will be for a short time a flow of suiiicient amount to insure. the refilling of the bowl after it has been flushed.
