To all whom t may concern.'

Be it known that I, EDWARD G. Hnnens, a citizen` ofl the United States, residin at Newark, county of Essex, and. State of ew Jersey, have invented certain new and useful Im rovements in Closet-Flushing Valves, fu described and represented in the following specification andthe .accompanying drawings, forming a part of the same.

The object of the present invention is to improve the construction of a-fiush-valve so as to increase its eiliciency, so as to automatically discharge air which enters the fiushingchamber, so as to obviate vibration and hammering, and so as to facilitate the. adjustment or regulation ofthe Hush-valve, and produce a greater or less lflushin of the xture to which the valve is attached.

The invention includes a special arrangement of the bleeding-hole or equalizing port which extends through .the diaphragm, and means to retain it in a preferred position to secure the automatic `cleansing or" such portv at each actuation' of the valve. M

It also includes the extension of an airshifter-pipe from the relief-valve to the upper part of the compression chamber, so that any air in the upper part of the compresvsion-chamber. is automatically discharged at each iushing movement. 1t also includes the attachment to the iiushing-s indle, of a sleeve-valve which, when the pu l`handle is operated, resses ,upon the diaphragm and 'cuts 0H t e escapev of any duid from the supply-chamber, except through the reliefva ve.

tion.

- The annexed drawing shows in Fig. -1 a 'longitudinal central section of the Hushvalve with its various attachments; Fig. 2 is an elevation of the relief-valve-box with the airsnifterpipe attached; Fig. 3 is an elevation of the dia hragm showing the re' ber; 6 the discharge-chamber; 7 the seat for the diaphragm; 8 the diaphragm; 9 the pull handle' 10 the sjndle moved by the pullhandle; l11 the re 1t also includes other details of construcf 'ef-valvestem; 12 the re-` equalizin port; 15 the air-snifter-pipe; 16 the hub o the diaphragm; and 17 t e recess for the relief-.valve-box vin the outer side of the compression-chamber. A. spiral-s ring 18 is fitted in the relief-valve-.box to hofd the relief-valve normall closed, thus preventing any escape of water` y the airipe. The relief-valve-box is attached to t e diaphra and has a relief-valve-seat 21 integral wlthl a hollow threaded projection 26 extending through the-diaphragm.

' In other Hush-valves the equalizing. port is drilled in the metal of thev compre 1onchamher, but in this invention is ex Y nded through the diaphragm so as to form a short lief-valve; 13 the relief-valve-boxi 14 the and straight passage between the supply and j compression-chambers, which conduces to a constant clearing of the passage, thus maintaining a reliable and uniform operation of the flush-valve.

ln the present invention this equalizing port vis preferably located n ar the -up er edge of the diaphragm close Xo the supp ychamber, so that every time the valve is ushed the fluid passing 'from the supply-v chamber into`the .boreof the seat 7 washes off the end of the port and keeps the port constantly open. 'The port thus o erates re liably in regulating the filling o the compression-chamber, which ultimately closes the channel around the inner end of the seat 7 at the close of the ushing operation.

The relief-valve-box is clamped upon the center of the diaphragm by hub 16, and the relief-valve-stem 11 projects through the hub in iine with the spindle 10. The stem is made square to form passages 20 through the huh.

The relief-vave is 'of piston-shapeand is held by the spring 18 in a position to normally close the passages 20.

The piston ts the ox loosely so as not to choke the outlet of the air-pipe, which extends into the side of the valve-box. -A

sleeve-valve 19 is shown in Fig. l attached to the spindle 10, and is ttedmovably to the bore of the diaphragm-sent.

The actuation of the pull-handle forces the sleeve toward the 'diaphragm as shown in Fig. Ll, and thus prevents the valve temporarilyfrom flushing, as it closes the channel 21, between the disphragm and its seat 7 e release of the handle draws bank the sleeve-valve and causes the flush to follow.

screw-driver b The supply-chamber 4'is supplied with water un er pressure, and the dischargechamber 6 is emity until the pull-handle is operated to pro uce the flushing movement.

Under these conditions the equalizing port permits the fluid vfrom the supply-chamber to radually fill the' compression-chamber un er the same pressure as the source of Supply. The actuation of the pull-handle ushes the relief-valve from' its seat, thus orming a communication between the topend of the airipe and the. passages around the stem of tlie relief-valve. This outlet reduces the pressure in the compressionchamber, and the super-pressure of the fluid I 4 in the supply-chamber pushes the dia phragm from its seat and permits the-'water in thesupply-chamber to escape in to the discharge-c amber 'through the channel 21 between'the diaphragm and its seat 7, as shown by the arrows 7 in Fig. 4.

The actuation of the pull-handle vnot only lifts the relief-valve from its seat to initiate 'the flushing, but the spindle 10presses u on the stem 11, as shown. in Fig. 4, and pu es the diaphragm fromits support or seat 7,

(see Fig. 4)"thus positively o ening the dia-y phragm for a'quick and e ectivefiushing movement. v I

- 'I'he degree to which the s indle 10 pushes open the diaphragm is regulated by a screw 25 seated in the recess 17 in the casing 17 around the valve-box. A cap 26 is screwed in the casing over the outer end of the screw 25z which end is notched to admit a which the screw can be set near'to or arther from the relief/valvebox, and thus determine the rapidity of dis.

charge to the dischar e-chamber. Such screw can be adjusted W ile the fiushivalve is in its o erating position.

It will e understood that the seat 7 projects from the upper part of the dischargechamber toward the compressionlchamber, and is surrounded upon its outer sides with water under pressure inthe chamber 4.

' It will be observed that the compressionchamber is completely cut oi from the supply-chamber except by the equalizingfport- 14. and that the diaphragm can only be pushed into the compression-chamber by pushing duid out through the vrelief valve.

iinally brings the'diaphragm against its seat 7, as'shown in Fig. 1, which-stops thelow Several defects in such flush-valves are corrected 1n the present construction. In

lmany previous constructions the equalizing port is located where the sediment in the yWater is liable to clog the necessarily small passage which forms this port.

The accumulation of air,.which is one of Vthe greatest defects in ordinary flush-valves,

is prevented in the present construction, by

-extending a so-,called vair-snifter-pipe 15 from the relief-valve-box to the upper part of the compression-chamber, sothat an air which 'is trapped in the compression-c am-f ber isv discharged atv the. first actuation of the flush-valve into the relief-valve-box, and

thence through the passage or passages around the valve-stem.

The rapidity of the waters movement through a ush-valve is aii'ected by the pressure of the "supply-fluid, and the present invention furnishes a means of regulating the degree in which the channel 21 for the fluid is opened when the pull-handle is acany pressure in the sup ly-chamber.

Leakage often occurs at the 'stuif' ingox of the valve-s indle 10 by the wear of the ordinary pac ing, and such leakage is prevented 1n thepresent lconstruction by providing the sti'ifling-box 22 with 'a washer 2 3 upon the outer sidev of the packving 24 and clam ing a spiral-spring 25 within the'stuingox 22 to keep the washer pressed elastically upon thel packing.

Such's ring-washer operates to compensate for t e 'wear of the packing, by crowding the same constantly upon the bottoml of the stuiling-boic', which is tapered as usual.

If desired, the lspindle 11 may `have a sleeve-valve attached' to it'within theseat 7 to contact with the vdiaphragm, but the sleeve-valve. v

`The compression-chamber 1s formed in an lother parts operate equally well without the auxiliary casing-27 screwed upon the outer side of the supply-chamber, and means is provided within the compression-chamber to locate the air-snifter-pipe so-that it extends from the relief-valve-box into the top of the compression-chamber.

Such means is requisite because the casing of the compression-chamber is necessarily made removable to introduce the dia` phragm and clamp it in position.

lThe air-'pipe is a part of the relief-valvebox, which is attached to the diaphragm,

' and is liable in assembling the parts to be the screwing of the auxiliary casing 27 upon the main casing 27. Any other suitable means may be used to thus locate the aireine.

:The drawing shows details of construction by which the parts are fitted and held together; but it is immaterial what constructive features are employed to embody the essential elements `which are pointed out in the claims.

' When tlie flush-valve is operating all thev tluid vented from the supply-chamber passes between the end of the sleeve-valve and the diaphragm, as shown by the arrow 7 in Fig. '4; but the connection of the sleevevalve 19 with the valve-spindle 10 is capable of arresting the current through the flushvalve at any moment, when from any cause it is undesirable vto permit the completion of the flushing operation.

Such arrest ofthe Hushing is controlled by pressing the pull-handle until the sleevevalve contacts with the diaphragm; this prevents any passage of fluid from the supplychamber to the discharge-chamber through the interior of the sleeve-valve. This construction therefore places the operation ot flushing entirely under the control ot' the operator.
