Application tiled April 12, '1909. Serial No. 489,535.

To all whom 'it may concern:

and WILLIAM i.. HUNTER, Jr.. both citizen geles, in the county of Los Angeles and Stute, of California, have invented a new and use- `ful Flushing Device, of which the following 2s a specification.

This invention relates to flushing devices, and the object of the invention is to provide a flushing device which may be connected direct to the service pipe supplying water under pressure and w ich may be operated to permit the discharge of water roni the device without shutting ot the source of supply from the delivery pipe which supplies the water under pressure. l

The device is distinguished from flushing devices of the ordinary type. which employ a receiving tank and which shut oil the supply of Water to the said tank when the lat ter has been filled.

The present device includes a tank, but

such tank'is always in communication with the supplyv pipe, and the water in the tank is thus always'under the pressure of that in the supply pipe. Referring to the drawings: Figure 1 is a vertical lonfitudinal section through the device. Fi is a cross section on line :c2-wz Fig. 1.A lfig. 3 is a section on line cz--xca Fig. 1.. Fig. 4 is `a plan view of the upper end of the tank. IFig. 5 is an enlarged, vertical, longitudinal section of one of the parts.

1 designates a, tank or intermediate chamber to which water is admitted under pressure from a supply pipe 2, the latter being in connectionwith the usual service pipe. A cheek valve 3`is arranged in the pipe 2 und a hand valve 4 is also provided.

The tank l at its upper end is provided wit-h a cup 5 which has a. ange (i screwed into the head .of the tank 1 A cross bar 7 extends across' the top of the cu 5 und forms a Guide for a valve stem 8,' t ie latter being slidable therein. 'lhe cup 5 is always open to the atmosphere, but is normally closed from communication with the tank 1 by means of an air valve 9 which is refcrablv heini-spherical as*v shown and Wliich seats against the flange 6.' The valve 9 has a stem 10 which 1s frictionally mounted on thesternv 8, the amount of friction being regulated by nut l1, whereinl the valve 9 can be adjusted along the stem `8. .At the lower l end of the valve stem S is an inverted cup 12 Ba 1t known thatl We, Fosren lV. B issrxrr i which acts as n float to operate the valve u z stem S and valve 5l, as will be explained. of the United States, residing at Los Ant The. vulve stem 8 is snlliciently long to perinit thc valve l2 (o hc adjusted into the lowcr purtof the tank, or into the upper part of thc tank. The lat-ter adjustment is shown in Fig. l and when so adjusted the air valve S) will open very early 1n the ilushing o eration so that the tank operates nearly lil-)te a gravity tank in that its interior bccomes open to the atmosphere quickly and remains open during,r nearly the whole of the flushing operation-` W'hen the valve 12 is nugnsted to the lower part of the tank, the tank acts substantially as a pressure tank during'the greater part of the flushing 0peration, in that the tank does not .become open to the atmosphere until nearly all o1 its water has escaped and the valve 12 has dropped to open nu' valve 9.

eads from the lower end of theV part of the valve chamber 16 being in permanent communication with the water chamber 15. The upper part of the central valve chamber 16 is normally out of! from communication with the water chamber and pipe 13 by a vulve 17 which is vieldingly pressed down against its sent. lxtendmg longitudixmlly of the walls of the central valve chamber 1G is a seriesof )assages 18 (sce Figs. 1 and 2), the u per en s of which lic in a circle immediate y below the valve 17 and the lower ends of the'passages 18 opening at the bottom of the central valve chamber 1G.

'rounds a central valve chamber 16, the lower Screwed to the lower end of the water chamber '15 is the valve operating device which comprises a casing 19,'tnere being a ball valve 20 normally seated at the upper end thereof und shuttmg 0H communication between the casing 19 and the valve chamber 16 and water chamber 15. A sleeve 21 is slidable in the casing 19 anda series of openings 22 are formed therein which are adaptr ed to permit water to flow therethrough into the lower part of the casing, when the sleeve 21 is in its lower position. "The sleeve 2l at its lower end has s flange 23 above which the sleeve is grooved to receive a riim7 24.

which strikes against an internal depenlin flange 25in the casing 19 to sto the upwar movement of the sleeve 21. rack 26 is connected at its upper end to the sleeve 21 and at its lower end is guided in a spider 27, the rack 2G bein' operated by a seg mental gear 28 on a s iaft 29 which extends throu rh the casing 19 and is equipped with a han le 3G. A pipe 31 leads from the lower end of the casing 19 and discharges the water to a basin or other place to be flushed. A. small pipe 32 is connected at its u per end with the cup 5 and at its lower en the ipe 32 passes throu h the wall of the casing 19 and through t ic flange 25 and serves to admit air through one of the openings 22 into the interior of the sleeve 21.

In operation the parts normally stand as shown in Fig. 1 and when it is desired to operate the device the handle 30 is depressed,

thereby lifting the sleeve 21 and shutting the openings 22, the sleeve 21 being thus raised the cushioning ring 24 strikes the lower edge of flange 25, whereupon further upward movement of the sleeve is arrested and i the handle is then released. As the sleeve 21 thus raises. it lifts the ball vali/e211 uriseatmg the latter from the upper end of the `casin 19, whereupon water from the water -cham r 15 enters past the ball valve 20 and flows into the interior of the sleeve 21 'and as the openings 22 are closed the water can not escape therefrom and the weight of the Water together with the force of its impact against the imperforate bottom of the sleeve 21 moves down the sleeve 21 until the openings 22 are below the flange 25, whereupon water from the water chamber 15 flows down therefrom, past the valve 20, into and through the sleeve 21 and out through the o nings 22 into the casing 19 and thence to t e pipe 31; durin this flow of water the ball valve 20 whic has been mechanically lifted by the sleeve 21 held up from its seat after the sleeve 21 has lowered by floating within the central valv'e chamber 16, its flotation therein being assisted by a partial vacuum formed within the upper part cf the chamber 16, which vacuum is caused by air being sucked out through the air passages 18 by the water in flowing across the lower endsof assages 18 in flowing from the water cham r 15 into the casing 19. `As water'continues to ilow out in this manner, this suction, however, gradually weakens owing to equalization of pressure atthe bottom of the central chamber 16 and the ball 2O gradually fails into its seat again upon the up er end of the casing 19, thereby shutting o further flow of water. The ball is kept unseated, however, for a sufficient time to enable the proper amount of water to pass out for the pur ose of Bushing, the parts being so designed that practically the entire amount of water within the tank 12 is discharged beforethe valve 20 seats. It will be noted that while the valve 2O is lifted and ,eva

' mulatcs therein and this outward movement of water from the tank l1 is facilitated by the opening of air valve 9, which is opened by movement of iloat 12, the latter moving down with the outfiowing water from the tank and as valve 9 thus o ns it permits air to enter the upper part o tank 1, thereby relieving an vacuum therein. which otherwise would orm and interfere with the free outward movement of water within the tank. Assoon as the valve 20 closes, the water aecumulates in the tank 1 and lifts'the lloat 12, thereby closing the valve 9. The float 12 is made 1n 'the form of an inverted cup, so that the water in lilling'in the tank l will seal the lower rtion of the cup-like valve 12 and act to orm an air chamber within the valve 12 and compress air therein to buoy or float the valve 12. The pipe 32 admits air to the interior of the sleeve 21, so that after the valve 20 has seated, the water which is within the. sleeve can readily flow out without becoming air bound.`

The purpose of the valve 17 is to permit air to escape from the central valve chamber as the valve 20 is lifted. The diameter of the valve 2O is nearly equal to that of the `valve chamber .1 5 and when it is lifted, were it not for the valve chamber 16 it would compress the air in the chamber which would nullify the effect of'the suction which is formed by air passing out through the air assages 18.
