The objects of this inventon are:
Firet, to provide such a structurewhch is a silnple and efiective hgh s;peed -devce thai; s economical to produce V i r Second to produce such a structure in Whieh the1 e are niproved auxliarystorage supply a=nd suctlon means to secure prompt fullaeton, and incidentally,to prevent Water ham'me a lhird, t 0 prqvide an improved Construction of toilet bowl xefill means for such a flush valve structure.
Objects pertainng to details and economies 01 construetion and operation Wll appear from the det-ailed descriPtion to follow. The invention s clearly defined in the clams.

The valve seat 77 is of abou-t t 1e dia'mter Ofthe valve plug 78. A plug 8 cl'o'ses the end of the 'bo're 77 and ;provide s a stop for the valve plg 78 in its open ,poslton.
9 s the eylindrical flush valve ehanber. 10 is the hydralic eup packi'ng which reciprocates as a piston in the same ami is connected to the upper part of: the valve body 7, and reciprocates as a plunger in the pressure chamber 9. j e

The auxiliary supply end storage chanber or cylinder ami water cushion are conxprised in the casing 5 in which there is dsposed a plunger 51 with hyclraulic cup packi lhe plunger 51 Inoves against a group o coiled spring-s 52 Which abut on the head 54. Thls auxiliary supply chamber can be dsposed in any convenent placa between fioers, ent irely u concealed, ami yet it does its work elfecft-ivly and provides an auxilian storage supply for a larga initial volume e fl 0w wl1ich inSures prompt and complete flushin- Ine;id.entall.-
it also prevents the water ammar Whic often occurs vvth flash valves. My valve vvll operate with any anxilary supply if of sufficent size ancl pressare. F01 tl1e usnal size of Water closet bowl, a vert-cal three nch pipe wth olosecl upper end, to provide an ar cushon, sin feet in length s suficienc.
I-Iaving descrbed tl1e various parts of my nvention, I Wlll 110W indicate ther operation.
WVhen the release valve 12 s openecl, water confinecl in the pressare chamber 9 is free to flow tbrough theport 135 nto tbe spillway charnber 91 uncler urge of the hydraullc cup 10 carrecl by thevalve 7. The valve 7 end ls face 71 s rasecl from its seat bycbe pressure Of tl1e water thereon, tbe spring 12 beng nsuflcently strong to resst the pressure of the W2LBI confined in the auxlary supply cha1nber 5. The waterrushes by the valve 7 end through the spillway chamber 91 through the ppi1g 3 into the closet bowl where the nsual flushng takeS place. W'hen the manual pressare on che valve 12 is releasecl, varous reactons take place. Water passes through the central bere 2 end tbrough the choked boro 73, graclually filling the pressure chamber 9, tbe spring 12 mean-' vvhle havng focecl tl1e valve 7 and its face 71 onto ts seat as the pressure has been releasecl. I/Vh en thepresSure chamber 9 becomes fillecl, pressure gradually s bult up and acts upon the byclraulc cup 10, tbe bottorn of the face 71, Che back of the collar 7 8 on the valve plug 78 ancl che front of the collar 78 of tbe plug 78. As ths pressare gradually increases, the valve plug 78 s I"Orcecl to s seat 77 by a force equal to tl1e clference betvveen the combhecl pressure of the spring 78 plus fl1e pressure on tbe front of the collar 7 8 and the pressare ai: the back of the collar 78 reactng in the bere in front of the plug 8.
'As the area of the hydraulc cup 10 is greater than the area of the valve face 71, che dfierence in areas under the same pressure holcls the valve firmly aganst its seat and assures a tight seal.
It can be seen that the full react-On .of the pressure of the water on the valve plng 78 cahnot takeplaoe untl tl1e pressure ohamber 9 s completely fillecl, and that the pressure chamber 9 fills at a precletermined rate (leendng on adjustment of: the ch0ke in the bore 73. By this means the length of time water Wll flow past the valve plug 78 and into the spllway 91 after tbe valve 7 anclts face 71 has becomeseatecl, ancl consequently the volume of water, may be aecurately determined to compensate for varous water supply pressare.
\ s graclually ncreasecl durng che whole clesng perod due to the filling or" the auxilary chamber under n creasing pressure, due to the yelding cushon acton of that devce. The pressure ncrease continues after the The pressure, of cours'e,
n the trap. That is to say, the refill s re f qu1red.
I have descrbed 1ny invention in the detals whch I prefer. I desre to state that the valve parte can be used Will1 otber auxlary snpply ancl cushoning means and the oushomng means are avalable in other relations. I clesre io clam invention specifically as well as broaclly as ponted out in the appended clarns.
Having t-hus descrbecly my invent-ion, what I claim as new and desre to secure by Letters Patent is:
1. In a flush valve structure, the combinaton of a suit-ablecasing with central cylnclrcal chamber, a plunger valve havng a rubber fece theren of smaller cliameter tl1an che plunger adaptecl to recprocate in che sacl cylincler chamber, a central large axial bere through tl1e bottom of said valve ancl a restrctecl axial bere at the top thereof for permttng the inflow of water to the central cylindrcal cha1nber to seal the valve, a cross borein said valve wth a plug valve vvth spring holding t slightly Open to be closed after theclosing of the n1an valve by he a'ctlon of water passing around the Valve plug and the accumulaton of pressure back of it, and anauxiliary supplychamber and cushor devce' comprisng a cylncler wth spring pressed plunger heren nterposed in che supply acljacent sacl valve, as clescrbecl.
2. In a fiush valve structur, the combination of a sutable casng with central cylnclrcal chamber, a plunger valve having a rubber face theren of smaller dameter than the plunge aclaptecl to reciprocate in the sacl cylncler chamber, a central large axial bore through the bottom of said valve and a restrcted axal bore at the top thereof for permitting the nflow of water to the central cylinclrcal chamber to seat the valve, a cross bore in saicl valve wth a plug valve with spring holding t slghtly open to beclosed after the olosng of che man valve by the acton of water kpassng around the valve plug and the accumulaton of pressare back of it, anol an auxiliary supply chamber and cushon devce ncerposecl in the supply adjacent sacl valve, as clescrbed.
3. In a flash valve structure, the combination of a suitable casing wth central cyln drical chamber, a plunger valve having a rubber face theren of smaller diameter than the plunger adapted to recprocate in the saicl cylncler chamber, a central large axal bere through che bottom of said valve and a restrctecl axial bere at the top thereof for permtting the nflow of water to the central cylnclrcal chamber to seat the valve, and a cross bere in said valve wth a plug Valve wth spring holding it slightly open to be closed after the closmg of the main valve by the action of water passing the valve plug and the accumulaton of pressure back of it, as descrbed.
4. In a flush valve strucfure, a plunger valve with automatic closing means, 1n combnation with an auxiliary supply and storage chamber and cushion devce comprising a cylinder with spring pressed plunger therein interposed in the supply adjacent said valve, as described. e
In witness whereof I have hereunto set my hand. k
