The bottom of they valve housing 16 is open, the opening being surrounded by a valve seat 18v arranged to .be closed by means of al supply valve 19.

k,The supply valve 19 `is actuated from a y inaf'ter designated simply as the float 27. .The float 27 is preferably cylindrical in threaded into an air fitting 35 whichV supports shape' and is formed around an axial tube 28 which ope .sthroughthe top and bottom of the oat 27 and is arranged to slideoverla vertical rod standard 29. rlhe float 27 is conn nected to the lever 23 by means'oii' an L-shaped arm 30 hinged to the extremity' of' the lever-23 at 31, and hinged to a clamp fitting 32 at 33. The fitting 32 is` clamped 'or soldered on a projecting extremity 4of the axial tube 28, as

illustrated in Fig. 3.

The standard 291s maintained `verticalby means of a` base member 34 into which it is kthreaded or otherwise secured. Thek base kcasting 34 can be so constructed as to formi apart of the iushing nipplell vor maybe clainped under the ilange of any of the presy ent nipples so as to maintain it vertical in the tankv 10. I

The upper extremity ofthe standard 29 is an open-bottomed, cylindrical float chamber 36 about the float 27. The float chamber 36 is Y 40'.

clamped to the fitting 35 by means of hollow sleeve or air tube '37 which is threaded theref on and acts to clamp the top of the float cham- `berand maintain it rigidly in position.

Passages 39 are formed in the fitting 35 whichallow air to escape from the float cham `ber 36 into the air tube 37. VThe upper'exf tremity of the tube37 is normally closed by means of a resilient washer carried in a concentric proj eotingcap 41on the air chamber 38. The cap 4l isprovided with discharge openings 42, and is formed by closing .thefupper extremity of a bearing tube 57 *,Which passes thru-.the float 38 and acts as a V slide or guide upon-the air tube 37.

It will be noted that the walls of the float 27 are, perforatedby means of openings 43 which 'allowl the `float to' fillandremain filled Witlrwater to a predeterminedheight so that will act both as aweight to openthe supply yalve 19 and as a float 'to close the valve 19.

.Let usassume that the mechanism is in ,i the aosition illustrated in FiO'. il.' YVater is now flowingl from the supply pipe into the .-standpipe 13 through the open valve seat 13 1,into-l the tank V11G- the :ball valve 1.2.being closedA to prevent discharge of the water. rEhe float-27 cannot rise with the rising water level in the tanl; 10, because of the fact, that the float chamber 36 acts as lan .airbell to prevent the water -from rising about t-heffloat 27. rlhe lioat will, therefore, maintain the positionof Fig. 1 unt-il the water levelpasses above the top of the float chamber 36 and liftsor floats the air chamber or float 38 as indicated Vin vbroken line at A in Fig. 1.V This .w

raises the washer40 from the extremity of the air tube37 and allows the air in the float lchamber l36 'to immediately escape through the passages 39, thetube 37 and the openings 42. This allows the water to immediately fill the oat chamber, lift the float 27, and iinmediately close the supply valve 19.

let willbe noted that thatk part of the iioa't vabove the openings 43 isr neverlilled with water and will always vbe buoyant to'operate the mechanism. That part of, the float below the oaeninos 4 3 Vtho filled with Water will have ne weight when submerged since theV water contained `therein will displace an i amount of water in the tank. j i596.

Let' us new assume that the tank isliushed vor in other ywords that the ball flush valve k12 is Vlifted from the flushing nipple 1l, as; n

.illustrated in 2. This allows the water te rushfrom theitanl 1 O and rapidly lowers' tn water level therein. Y The float 27, how# f) since 'it is completely vsurrounded by vthe ier, cannot fall with'the falling water level water in the float chamber 36,'which cannotV escape from the vfloat chamber until air is admitted 'hereto todisplace it. Therefore, the float 27 will remainraised Or suspended and will maintain the supply valve 19 closed until lthe water level reaches the open bottom of the float chamber 36. rlhis will allow airV to rush-in at the open bottom to immediately Vdisplace the water therein and allow the. weight of the water within the float 27 to drop the float to the position of Fig. l,quiclly opening the supply valve v19. i Y

The impact of the failing float absorbed by the remainingv water in the tank lO, and the float finally stopped by i'neans of a rubber cushion 44, wnich*surrounds the standar-(i529 above the base member 34. The

' .11.11 is partially impaetot the rising float is absorbed by. a Y

similm rubber Vcushionwhich is compressed between thetop the float and the air fitting 35. i i i' T he supply valye 19 will operate under conditions Vwhere 'the pressure in the supply pipe is relatively low; For operations `where there is a relatively high'pressure in the Vsupply pipe a valve, such asillustrated in This valve is ed7 and claimed more in Figs. 6 and 7, is preferred. illustrated, desc detail in applieauts kcopsndingy application, rio. 269,915, Jfiled April 14, 1923, which issued.
