with the compartment 12, and a needle valve 23 in said valve casing governs the flow of water from the compartment 7 into this connection, while asimilar valve 23 in the passage 22 of said connection governs the .flow of water from said connection into the compartment 12. Allthree valves 19, 23 and :23 areremovable for cleaning, repairs or other purposes and are adjustable from the exterior for regulating the time flow of the water-between the compartments or for outtingoft'the flow of water when desired. The valve23. is preferably .set so that the compartment 12' will be filled for a flush regulating action within a-given period of time after having been emptied,-wliile the valve .19 is so adjusted; as to effect a replenishment ofthe pressure compartment 7, after eachflush action, within less periods of 7 time than reiquired to replenish the compartment-'12 so ing to the discharge outlet that after each flush action the valve 16 will be. automatically closed for a cutofl action by the pressure in the compartment 7 while .the compartment 12 is being refilled ior the subsequent flushing action, While valve 19 is-Inaintained in action, Valve 23 maybe closed when desired to cut out the automatic action and permit the valve device to be manually operated, as hereinafter described, without disturbing the adjustment of valve 23, which maybe left set as long as it'is desired to maintainflush actions 'at predetermined periods in the .automatic operation of the valve. Y

The casing is formedtoprovide an annular well 24 coextensive in ,depth with the chambers 7 and 8 and communicating with the chamber 8 at its top and communicating atits bottom with a drain passage 25 lead- 14. This well is filled with water flowing from chamber 7 to chamber 8, as hereinafter described, and; the water is retained in said chamber 8 and well 24 until the end of aflushing action through the main valve 16 on account of'a preponderance of pressure in the outlet 14 at-all times except at the'end of a flushing action. A

passage 26 and. pipe 27 connect the outlet 14 with the top of chamber 8to allow air to enter during thedischarge of water from said chambers 12 and 8 and the well 24.

The partition-6 is providedwith a port affording communication between the com- , partments 7 and 8, said port having a valve .its upper and outwardly through seat 28 against which a relief valve 29 is adapted to close upward. The relief valve is carried by a hollow or cylindrical stem 30 depending from the diaphragm 10 and carried by a clamping member 31 engaging the underside of the diaphragm. This clamping member 31 is in threaded engagement with a clamping member 32 bearing against the diaphragm 10 within the chamber 12, said clamping member having a passage communicating with the stem 30 and provided with a seat 33 for a vertically movable ball float valve 34, said valve being movable upwardly and downwardly in a cage formed by rods 35' extending between the member 32 and a head plate36, carrying a tubular guide tube or nipple 37 through which the float valve stem extends,s aid stem comprising telescopic sections 38 and 39, the former fixed to the ball and'the latter slidable in the nipple 37, the section 38 having at its upper end a contact head 38 and the section 39having at I lower ends contact heads 39 and 39 A coiled spring 40.is disposed in the compartment 8 about the stem 30 and about a stationary guide tube 41 carried by the partition 6 and in which said stem is movable, said spring operating to close valve 29 against its seat 28 to allow compartment 7 to fill through 19 and 18 to cut oii flushing action. Ports 42 are formed inthe stem 30 for communication with the chamber 8-and well 24 when the valve 39 is opened for the flow of water from the relief compartment 7 through ports 43 in the guide tube 41 into the chamber 8 and thence into the well 24 and drain passage 25.

Theyguide tube or nipple is movable ina downof the valve member 34. the top of the casing is a by a cap 47 and having arbushing 48 and a washer being clamped with a rubber disk 50 against a shoulder on the exterior of the bonnet. Movably mounted in the bonnet and attached to the disk 50 is a plunger .stem 51 normally held raised by a spring 52 and carrying a button, knob. or like actuating device 53 projecting the cap 47, by means of which the plunger may. be manually depressed against the resistance of the spring. On the underside of the disk 50 is a contact piece 54 adapted, 011 the depression of the plunger, to engage the guide tube or nipple 37 whereby motion may be transmitted through the float valve cage to the diaon which the head '39 of the i valve ;29 tor a hand-operated flush action.

A clamping screw 53- -is;provided'- on cap 47 are closed,

scends. against the resistance of spring and pressure in compar ment 7' and opens valve29, whereupon, owing to the reduced pressure in compartment Sand well 24 as compared with that in compartment 7, a

primary relief action takes place through a flow of a portion of the waterfrom compartment 7 through ports 42 and 43 into compartment 8 and well 24. Valve 16 now opensand water flows to outlet 14 from' compa'rtment 11 and inlet 13 fora main fiushingaction. During these actions float valve 34 remains closed, but the diaphragm 1O continues'to descend until contacts 38 and 39 engage, thus holding valve 34 from furtherdownward movementwhile the diaphragm 10 continues to move downward to-its limit.

On such further downward movement of diaphragm 10 valve 34 is lifted off its seat 33, and since the valve 34 is buoyant its stem section 38 slides upward on its stem section 39, and water flows from the compartment 12 into compartment 8 and well 24. The pres,- surein compartment 12 being thus relieved spring 40 closes valve 29 allowing pressure to be built up in compartment 7 The pressure in the-compartment 7 now causes valve 16 to close to cut oil the main flush, and im mediately thereafter compartment 12 empties into compartment 8 and well 24, 25 and outlet by gravity to the 14, and float valve 34 returns 1. During the position shown in Figure main flush, the pressure in the outlet 14 be ing greater than that in chamber-8 and well 24. the water contained in said chamber and well is retained therein.
