ing parts eXtendthrough the enclosing. wall housing the valve mechanism, and such parts must" be packed to prevent the escape of Such packings if they prevent the escape of water make the parts hardto operate and they are very liableto' deterioration.

One of the: primary objects of the presen wholly enclosed, and with operating meoha- 'nism' outside the enclosing wall, the" wall having flexible portions, in thenature of diaphragms, which are laterally movable, to enable-operation of the valve'mechanism;

Another object fisthe provision of a' dia:-- phragm operated'flush valve, whereinthe initial opening of the .flush valve admits the full water pressure to the diaphragm to opcrate the same, and wherein auxiliary mecha-- nism is provided externally operatedto'em able; the inlet of initial pressure tounseat the flush valve. Another' object is the provision of mechanism for draining the diaphragm chamber after the flushing operation to' enable seating of the flush valve, externally-operated, and without direct connection with 'the external operatingmechanism. Q Another object is thezprovision insueh ap paratus, of means facilitating inspection and removal of the operating parts.

An'otherobject is the provision ofa rela-' tively simple and relatively inexpensive ap' paratus capable of operation with the usual tank, or :with a siphon filled tank, and adapted to be arranged within the wall of the: bath-room. V v a 'W ith these and other objects in view the invention consists in'the construction and 7 novel combination of parts fully described hereinafter, illustrated in, the accompanylng drawings,- and polnted out. 1n the claims appended hereto, it beingunderstood that various changes 1n the form, proportion, size sr'o- 'n osoAivYAit AND some I and 'minor'details of constructioniwithin the scope of'theclaims, may be resorted towith out departing' frlom the spirit of the inven Inthe-drawings forming apart hereo'if:

I "Fig. 1 isa side'elev'ation of, the improved apparatus. I

' Flg'. 2"i's an enlarged detail in section of V the flushing mechanism. c i In the-present embodinfentof the inven ,tion, a valve casing l is provided having an inlet 2 atone side; which is connected by a pipe 3, with a compression tankt, the said tank being adapted to contain" a definite charge of watch-which during its entrance to the tank compresses the 'a ir'ih the top-of the tank. f I

The top of the c'asingl is closed by a plug 5 threaded intoan' opening in the top; and the' said plug has a handle6 for convenience-in manipulatingthe same. lntermediateitsitop and bottom'the casing has a partition 7w pro vided with a port 7 normally closed by avalvei in'the form of a cup 8', having a filling 9 of packing which rests upon the upper-face of the partition 7 a when the valve is in closed position. I

The valve has astem 12, which moves in a bearing 13 supported by the cap 5 before mentioned, the cap having arms 14, which are connected with thebearing'. v At its upper end the stem has a longitudinallyextending slot 15', through which passes a pin 16, the endsof the pin being entered into openings in'the re: duc'ed portion of the cap which engages with in the opening of the casing 1.v Thus. the valve and stem areconnected tothe cap with a lost motion connection, the pin limiting'the movement of the valve.

A spring 17 encircles the stem between the bearing 13 and'the valve 89,normally holding the valve to its seat,.and a guide collar 18 is threaded on to the lower end of the stem below the valve,thecollar fittingl'oosely within the port, and extending belowv thelower end of the stem as shown. v

The'lower end of the casing is providedwith a lateral port from which leads a pipe 19'to the bowl to be flushed. Water is sup plied to the chamber 10 of the casing, and to the tank 4, by means of a pipe 20 from a suitable source of supply, the pipe having a cheer: valve 21 interposed therein, to prevent return of water to the source ofsupply.

At its lower end the valve casing 1 is enlargedlaterally to provide acircular head 22, which is concav-o-convex, and arranged with its concavity downward. This head forms one wall of a diaphragm chamber, the other wall being formed by ahead 23', which issecured to the head 22 by threaded stems and wingnuts shown at 24. i

A diaphragm 25 of suitable material is arranged within the chamber, the edges of the diaphragm being clamped between the abutting edges of the heads 22 and 23, and anopening or port 26 is provided between the chamber ll'of the casing and the diaphragm chamber. Normally the diaphragm lies in con-.

cave-convex form on the inner face of the head 23, as shown in Fig. 2, and water is admitted to the chamber beneath the diaphragm when the valve 8+9 is opened, by means of a passage 27, which extends through the wall of the chamber 11, and through the wall of the head 2.3, a check valve 28 being provided v at the inlet end of the passage. Referring to Fig. 2, it will be seen that the passage27 extends outwardly and downwardly, then inwardly anddownwardly, and then vert cally upward, and that the inlet end is enlarged as shown at 29 for the check valve.

1 It will be apparent from the-description that when the valve 89 begins to lift, water will fiow through the passage 27, past the 1 the valve will be lifted through the engagement of the rod 30 with the stem 12. Thus the valve 89 is lifted by thediaphragm, but water must be admitted to the-space below the diaphragm to provide initial lifting'movement of the valve before water can enter the passage 27. In order to enable an initial flow beneath the diaphragm, a passage '33 1S provided leading from the chamber 10 to the portion 34 of a chamber, consisting of the said portion and a portion 35 of less diameter, the said chamber being provided in an extension from the casing 1.

A valveseat 36 is provided between the portions of the chamber, and a valve 37 simi lar to the valve 8 9 cooperates with the seat,

the valve moving downward to open communication between the parts 34 and 35 of the chamber, and moving upward to close the communication. The lower end of theportion 34 of the chamber is closed by a threaded bearing against the diaphragm.

plug 38, and this plug is recessed on its inner face to receive a spring 39which engages the lower end of the valve, actingn ormally to seat the same. The valve may be unseated by means of a push button 41, slidablymountedin a bearing nipple, 42 in the cap 43 which is threaded onto the upperend of the extension 40. The button bears against a diaphragm' 44clamped between the cap and the end of the extensioinjand the valve has a stem 45 provided with a head 46 at its upper end,

It will'be apparent from the description that when the button 41 is depressed, the valve will be opened, enabling water to flow from-the chamber 10, through the passage 33 and the portion 34 of the chamber into the portion 35. From this portion a passage 47 leads to the passage 27.

The operation of this part of the mechanism is as follows. In order to flush the bowl, the button 41 is depressed. This opens the valve 37, and water flows from the chamber 10 through the passage 33, the chamber.

3435, and thepassage 47,into the lower end of the passage 27 ,lifting the diaphragm 25.

and openingthe valve 8-9. The opening of the valve 89 opens the passage 27, and water may now flow directly from the chamber I '10 into the diaphragm chamber, beneath the diaphragm, andthe closing of the valve 37 under the influence of the spring 39 is no longer material to the operation of supplying water to the space. beneath the diaphragm. When the valve 89 is lifted, the water flows from the tank 4, through the pipe 19, to the bowl, thoroughly flushing the same. The diaphragm chamber, thatis, that portion of the same below'the diaphragm is enabled to drain througha passage 48 into the chamber 11. The rate of the flow through the passage 48 is regulated by a needle valve 49, which may be adjusted by a handled screw 50; Theneedle valve is in a nipple 51 extending downwardly from the head 22, and the outer-end of the nipple is closed by a cap 52, having a threaded opening through whichthescrew 50 extends. r

A diaphragm 53 is clamped between the cap and the end of the nipple. and the lower end of the needle. valve rests on the diaphragm. By turning the handled screw 50 in the proper direction, the extent of opening of the needle valve may be adjusted. In Fig. 1, the apparatus is shown arranged within the wall of a bathroom,. for instance. so that the tank andthe other mechanism is concealed. In order to enable operationof the push button 41 outside the wall, a panel opening is provided, normally closed by a panel 55. r

A bracket 56 is. secured to the inner face of the panehand an elbow lever composed'of arms 57 and .58 is pivoted to the bracket.

rests upon thepush"button- 4&1; The other arm 58'has an extension 59 passing through an opening in the panel, and provided with a 'buttontO. When itisdesired to flush the bowl, the buttoni 60*is pressed. inwardly. This presses the'button' d1 downward, and

initiates the flow of the water b'eneaththo diaphragm V a The opening 26 is a vent opening. Itwili be apparent that the tank i might supplied with water by means of a siphon, 1f desired, instead of directly through the casing 1. VVherethe water contains grit, such as" sand, it 1s advisable toapply arubber sleeve overftl'ie bearing 31, the sleeve engaging the hearing at; one end, and the rod; 30' at the; other. This W111 prevent theentrance of grit intothe di'aphragm chamber, 7 In some cases it Will be ladvis'able to place a spring above.

the'check 28. The entire mechanism is enclosed no part thereof extending beyond the casing. 1. and its associated parts. 7 V

The valve 87 is operated throughthe anphragm "44,- so that none of the connecting parts of the valveextend through the casing. This is true also of the adjusting mechanism for the needle valve."lVater pressureis re I liedv upon to openthe flush'valve. An observation opening isprovided,-indicated at 60. This is 'closediby a disk 61 of glass.

It will be apparent from the description and drawings, that the discharge isautomatically held open until the pressure in the tank reaches atmospheriqthat is, until-the tank is entirely'empty; As long as there is water in-the tank the diaphragm chamber does not drain, and it commences to drain when the tank is empty. The static head beneath the diaphragm is sufiicient to hold the diaphragm lifted. until'the chamber 10 is empty, and the tension of the spring 17 exceeds the pressure below the valve,

When the water begins to flow from the compression tanlgthe pressure gradually decreases, and near the-end there is a low pressnre,or a slight partialvacumn- In order to compensate for this, and to insure emptying of the tank, a pipe extends from the top of the compression tank to-the top of chamber 11; With. this arrangement, the entire contents ofthe tank are always discharged. The pipe 70 is provided with the usual check valve 71' toretain the pressure in the tank When it is filling;
