Slidable vertically in 'the chamber :1: is a cup F 'adapted to contain a liquid conveniently glycerin or any liquid Securedl to-the bottoni ofthe cup is a stemf whichy extends through a Asuitable stufiingv boiotziii thepartition b andhas threaded engagement'at its lowerend with a double valve closure for the valve -the partition c andcomprisesfa connecting .item/E extending through said aperture in the partition c and approximately its lower is veylindric'and but slightly smaller in f fdiameter than the aperture in said partition Sand of small .size at its middle part and to *rear its upper end. Said connecting stem is j screw threaded at 'its lower end to receive ...which holds the washer in place and whereby the packing washer e and the nut e thereon l-the inner seat in said partition is closed when -l-the cup is elevated. Secured on lthe upper end ofsaid connecting stem E, is a packing .l is threaded a stud washer el and nut e3 positioned' to close the upper Seat in the partition c when the cup fis at its lowest position. Astemf in axial alinein'ent with the stem f projects upwardly fremrthe bottoni of thecup, -and is ofv a length aeshown-to extend normally above the casing B, and through a Iianged cover G vwhich,closes the upper end of the casing .when secured in place.

lRigidlyV connected with said cover by means ofthe integral arm, or rod g, one in each side of the cup7 is a piston G through which thestern f passes and through Iwhich Vis'pro'vided a vertic lpassage way g in which l :in g2, lon itiidinally slot tedy at its lower enc to vary t e o ening from `zthe.passage. Saidv stud pin is s otted. at its flipper end to afford engagement with a screw r,driver or other suitable tool inserted through lan apertureg3 in alinement therewithin the cover G, normally closed by a plu g1. Withdow in said piston and opening nwardly therethrough is a valve as shown comprising a chamber in the piston into which a-relatively small aperture opens centrally through the top, and in the bottom of which is threait yspring g engages at one end on the f and at the other 'engages beneath sai push pin G2 which as shown is recessedl at its lower end to receive-the upper end of the same and acts to hold the cup F, normally elevated as y shown in Fig. l `with the passage through the partition c of' the inner valve casing closed from below.

The operation -is as follows: The cup F is iilled with oil or any suitable fluid preferably one that will not readily freeze, and they flushing valve bieing connected with the supply pipe c and the flush or discharge piped/,1' l

the water or other fluid to be controlled flows inwardly through the aperture in the closure filling the chamber formed in the inrer valve casing C and closure D, as shown in ig 1. wardly against the pressure ofrthe spring the valve in the inner side ofethe' partition'c is opened permitting the watenrm said inner chamber to flow therethroughind the pres'- sure being reduced above the closure D, theY direct upward pressure from the inlet pipe raises the closure D forcing the same into the sleeve or inner valve casing C and starting the flush. The downward movement of the cup causes the regulating iiuid to flow through the piston, the ball valve in the pis-4 ton facilitating the flow. When the push pin is released the spring forces the cup upwardly, this forces the fluid upwar y through the piston, but as the ball valve immediately closes the fluid must pass through the restricted passage in the piston which as before described is controlled by the stud pin ggl -"l5`.his retards'th'e upward flow of' course permitting the cup to rise at arate dependent on the delivery through `thepiston. 'The lf the push pin be forced down- 'l ioo flush will continue until the cup rises sufli'- 1 ciently to close the valve --on the innersiili'eofv the head c. As the cup rises the ,vent va'lve in the upper valve vcasing isjcpeneu andinasy much asthe smaller part of the connecting stein is then-in the. .vent passage' or a erture in the partition c the valve closure E) rises into the casing quickly and the fiush'will c011- i. tinue with full force until theV larger part of the connecting stein enters said a erture.

rFhis retards further iiow through t e vent and the closure D begins todescend soon decreasing the flow sufficiently to break the siphon in 'the closet iiushed but permitting enough water to pass to afford the'after ll.

The 110W ,for the after :fill'will continue' until the closure is forced slowly and gently down pon the casing. A portion of the water fromthe -inlet pi e now is forced inwardly through the smal aperture d2 at the bottom thereof, into the inner water chamber, quickly forcing the closure downwardly into its `seat and against inlet pressure. Should the cup be helddown the vent valve in the .10 partition is closed from above" preventing i1`,shi`ng,y except as the cup rises or is vintermediate its extreme positions ifo-prevent resistance through air )rassure an aperture his provided in the casing below the-normal position of the'cu to permit the escape .ofair. therethrongh'fw ien: tlie cup is forced downwardly, in a like manner registerapertures 7i areprovided near the top of said ,casngand in the to ofthe cup to permit the escape of air from a ove the same and to ermit a. tool to be inserted to hold the cup om rotation when it is desired to unthread the push pin, in separating the parts or assem- "hlingthe saine. p The regulation is secured -by adjusting the vfplug'or push pin g2 outwardly or inwardly in the piston thus increasingor restricting the passage therethrough'as described. it be- :ng obvious that increasing the delivery period while creasing the rateof delivery therethrough extendslthe flushing period.

'While' I have `described my invention as embodied with a non-movable piston and a kmovable cup either `may be movable relatively to the other. l therefore do not purpose limiting this application otherwise than necessitated. by the prior art as many details y ofl` construction maybe varied without de- 40 parting from the principles of my invention.'
