y Application lcd June 10,V

- My invention aims, to provide improved valves such -as are generally employed in flushl tanks, andinore lparticularly contemplateszimproved iillingvalves.

v In -theaccoinpanying drawing wherein I have shown one selected embodiment of my Fig. 1is a sectional viewV in elevation showing my improved valve applied toga flush 10 tank, parts being broken away ;y and'y l v v ball-cock `bodiment of my invention there shown, `my improved valveis arranged 1n a tank 10 which ment to the bottom of thetank. i f I 1 The inlet pipe S11 is* shown (see Fig. 1*) as having radial ports 12above a valve seat 13 i which is ,provided at' the upper end yof al restricted bore of the pipe. Above theports 12 -I have vhere shown adeflector 14 for the jets issuing from them'.I This deflector is preferablyintegral with theinlet pipe and present-s a downwardly curved annular surface todivrect thejets against the bottom of the tank,

The inlet pipe preferably "extends up in the tankl to about the desired water level and the stem 15 of a valve 16 Whichcooperates i f vwith' the seat 13 is guided inthe pipe herein by' means of a block '17 shown'as being thread- 1 i cd on the stem and projecting slightly above thefupper open end of the pipe 11.

I have here shown a float V18 securedto anv i arm of a lever 19 which is pivotally mounted on a lug or ear 20 at the Vupper end of thev ypipe 11. This lever lis `shown las, `L-shaped (Fig. 2) and carries aroller 21operatively to engage the valve stem block 17 to close'the i valve when the ball rises to a predetermined level. v

To secure a quick refillingof the tank after flushing and to eliminate -some ofthe noise incident thereto, I provide means to permit V.the valve tov remain fully open until the tank is as full `as desired. Io this end I have shown the float lever 19 as extending' across the top of the pipe 11 and having a roller 22 securedto its end to cooperate with a spring-V urged cam, herein shown as an arm 23 pivoted on an ear or lug 24 on the pipe 11 and-near Vthe bottom of the tankand presenting a more orl less abrupt camshoulder 25, on one side,

yover which the roller must ride during the een Sagem@ 'ailing :Operation 4 This arm is. shown as ,being urgedv against the `periphery 'ofthe roller 22lby means ofr ai i Y spring 2,6.-which is carried on a rod 27 that yis mounted on the-upper end of the ear 20 whichV provides a fixed.abutment y for 'the i spring. To vary the; compression ,of the to thel arm 19 to provide ,for varying the ,length ofthe leverYV "arm" thereby to regulate betweenhmits the level to vwhich `the lwater can risefbefore the` valve-js closed. For eX- ample, if-the arm is'shortened thewater will rise higherbefore the roller. 22 overcomes the compression-of spring -26 and'snaps overthe abrupt cam shoulder 25. n On the yother hand, s y if more waterthan is needed for eiiicientfiushy ing is being admitted, 'the arm may be lengthened and thus effect a saving of fwater.V

Referring to Fig. 1, lI have there shown a Siphon-type of Hushl valve Well adapted for use with my ball-cock valve.v The flush pipe 29 pzasse'sthrough the Ybottoni Vofr the tank to'` about 'the normal: water levelY therein and near the bottom, preferably lhas holes 30l therein to initiate the flushing action.

VAround thepipe- 29 I have shown a bell casing 31 carrying a tube 32 slightlydarger than `the lpipe 29 which is adapted to seatfonr a vsoft Vgasket or Washer 33 at the bottom-of the tank to prevent water fromv passing vthrough the openings 30 until the ybell isy raised by ahand lever` ofthe usualtype (not shown) attached-tothe eye 34 `of the bell.,

W hen the Hush valve is operated, the bell 33? and its attached tube 34 are lifted, permit-` ting water to lstart flowing through the holes 32 and'water in the bell Will be lifted ,by itv to start thesiphon actionoverthe top'4 of the i v s tube 31'.` rIhev Siphon action will Athenfcontinue until the tank is vpractically empty.l s 2 Fromthe foregoing description it will be",V 1 l observed that I have provided a comparatively simple and effective mechanism which not only reduces the noise incident lto filling thek yflushftank but also enables somev economy in Water consumption. kvAlso, my :improved Y v flushing valve increases the eiieency of the flushing action and reduces the noisey incident thereto.

' Obviousl iny invention is capable oli ma'ny different embodiments.

What I claim and desire to secure by Letters Patent is:

yclose the valve anda spring urged can-1- cooperating with vthefiloat lever lto hold it in- Yoperative and to permit the valve to Aremain and a spring-.urged pivot-allyV mounted cam open until the tank is lled tothe desired level. Y

2. In a ball-coek valve for flushtanks, inletvalve,'a Heat ylever for closing the valve,

In' a ball-cock valve, a float lever vfor closingvth-e .valve, said leverl having Van exv tension, a roller on said extension,.a pivoted arm presenting al cam cooperating with said 'roller anda coni-pression spring normally urging said arm against said roller to cause the cainto resist 'the ris-ing movement of the float until theivater reaches fthe desired level f land then to per it quick closure of the valve by the float. y Y
