VALVE DEVICE.

This invention relates to valve devices and more particularly to flush valves for toilet fixtures.

One object of the invention is to incorpoy Vvalve will not be unseated in the closing of rthe main valve should the operating mechanism be held in valve open position. V

Another' object of the invention is to have the actuating mechanism for the auxiliary valve operable through the guide.v of the main valve and thus reduce the height of the valve device by having said actuating mechanism closer to the main valve.

A further object of the invention is to provide the auxiliary valve on the main valve with a spring mounting in vorder to insure proper and quick closingrof the auxiliary valve when released.

A further object of the invention is to so form the seat for the auxiliary valve on the main valve that the seat forming means provides a convenient guide for the spring of the pressure reducer which is associated with the main valve.

A further object of the invention is to incorporate the housing for the packing of the timing pin directly in the valve housing so that the packing assembly may be easily made at a reduced cost-of manufacture and with a minimum number of parts.

A further object of the invention is to ieciprocably mount theV auxiliary valve'on the main valve and to provide a pivotally mounted lever on the main valve for actuating the' auxiliary valve through the valve actuating' mechanism which iscarried bythe main housing of the device.

The invention consists further in the matters hereinafter described and claimed.

A In the accompanying drawings@ I VF 1 is a vertical sectional view through a valve device of our invention;

1921i. serial No. 284,132.

Fig. 2 is a side view of the guide to be hereinafter described;

F 3 is a top plan view of the same; and Fig. 4 illustrates the action of the depressible pin to be hereinafter described. Y The valve device -of our invention comprisesV a main housing l'of cast brass or other suitable material. The housing 1 is provided with a passage for the, ow of liquids therethrough andsuch passage includes a chamber 2 within the housing and inlet and outlet connections 3, 4 at the opposite ends of the passage witht-he inlet connection l3 in constant communication with said chamber. the outlet connection 4 by an upright cylinder 5 having its lower end cast integral with the housing and opening into said outletconnection. Said cylinder extends upward though the chamber 2 andhas its upper end forming a seat for the main valve 6 which .controls the flow of vliquids through the housing 1 from inlet 3 to outlet 4. The connections 3 and 4 may be threaded for attachment .to the source of water supply and toilet fixture, respectively.

The main valve is in the form of a pis- Vton valve fitting within a cylindricchamber 7 provided in the housing 1 above the chamber 2 and forming an upward continuation thereof. The piston valve 6 has a sliding Afit in Vchamber 7 and divides the latter from chamber 2 in all positions of the valve, whether open or closed. The valve 6 has a sealing leatherS which engages the inner wall of the chamber? to seal it from chamber 2 in all positions of the valve.

The head of the piston valve 6 is formed by ,a metal plate or disc 6, to the under side of which is secured a depending tubular guide 9 having longitudinally extending radial webs 10 which engage the inner Surface of the cylinder 5 to guide the piston 6 in its opening and closing movements. `f The webs 10 are made long enough so as to hold the main valve 6 central in all positions of its movementand thus provide for a silent operating valve by preventing chattering or hammering.

The latter is divided fromrv The tubular guide 9 has screw-threaded Y and is held inplace by a metal cup-shaped retainer 12 so as ,to seaton the upper edgev valve 15 has a stem 16 which extends down- CAD ward through the tubular projection 13 and into the guide 9 through a bearing spider 17 at the upper end of the guide. The spider holds the valve central and guides it in its openingand closing movements. By this form of structure anon-tilting reliei valve may be employed.

To close thevalve 15 and maintain it rtight against its seat when closed, we provide a coiled spring 18 about the stem'16 between the spider 17 and an arm 19 to which the lower end of the stem is connected. Said arm 19'is `one ot the arms ot' a lever 2O which is fulcrumed at 21 on a lug 22 carried by the guide 9 at the upper end oi' a vertical slot 23 in the cylindriewall of said guide, as shown in Fig. 2. rIhe spring 1S presses down on the arm 19 and thusV closes the valve. The stem 16 is connected to the arm 19 in any desired manner, as for example by having an enlargement 24 on the lower end ot the stem beneath the arm 19 and a reduced por'- tionV 25 of the stem extending through a suitableslot or openingl in the arm.

A by-pass 26 is cored in a boss 1a on the housing '1 on the intake sideV of the `valve during the casting oit the housing. Said by-pass is enlarged where it opens into 'thi inlet connection 3 so as to allow tor a free and uninterruptedilow elE `liquids into the passage. The wall 27 et the housing on the rear side of the by-pass 26 extends downward inthe liow through the connection 3 so as to provide a baille 'for directing liquids into the passage 26. A port or hole 2Sl is drilled through the wall 27 at the upper end oi" the passage 26 so as to provide a communication between said passage and the chamber 7 'above the piston valve 6 and thus permit liquids to lill the. chamber 7 from the intake side of thevalve. ,i

' The upper surface ot the piston Vvalve 6 as exposed to the water pressure in the chainber 7 is greater in area than the under sui'- face of the valve which is exposed to the water pressure in the chamber 2 when the valve is closed. The result is that, although the pressure in the chamber 7 will be the same as on the intakeside oi the valve, the valve 6 would be held closed against its seat at the upper end Vot the cylinder 4 by reason of the larger area being exposed to the pressure in the chamber 7.

Arranged in the chamber' 7 above the piston valve 6 is a coiled spring 29 having its lower portion Ybearing against the plate 6'u1 about the tubularprojection 13. The upper end of the spring 29 bears against an adjusting nut 30 on a threaded stud 31 which extends into a recess 32 provided in a cap or cover 33 screwed on or otherwise removably connected with the housing over the top of the chamber 7 Theupper end oi the stud 31 fits in a concave seat'32l in the recess 32 to hold the stud from lateral displacement.

The nut 30 lits in said recess 32 and is held in adjusted position on the stud by a locli nut 84.- The spring 29 has a tension less thanthehydraulic pressure required to open the valve 6. The stud, nut, and recess assembly at the cover 33 and the tubular projection 13 at the main valve 6 provide a guide and support for the opposite ends of the spring 29 and hold it in central position.v VThe nut 30 is channeled or grooved on its under side to receive the adjacent end of thevspring and hold it from displacenient with respect to the nut.

The spring assembly just described provides a pressure reducer within the housing 1 andv enables the pressure at which the liquids are discharged past the valve 6 to beV reduced to the pressureA desired and thereby prevent Vsplashing and' violent action when the valve device is used with a high pressure system. By adjusting the nut 3() the tension of the spring 29 may be regulated so as to reduce the pressureV at which the liquids are discharged frein the device to the low pressure desired- Thus the valve may be set to discharge the least amount ot liquids at the lowest pressure desired and economically function without waste of liquids or waste of pressure.

When equipping tall buildings, suoli as employed for offices, hotels, apartments, and the like, the Ypressures at which. the various valves are desired vto operate may be set to accord with the pressure Vconditions existing at different levels and thus provide for economic operation of the valves and the amount o't' liquids employed in the flushing operation. 'In order that the water for the system for an entire building may reach the uppermost floors, it is necessary to generate a considerable pressure in the system. This pressure is considerably higher at the lower floors than at the upper floors, and as a result our improved flush valves can be economically used because the pressure reducers incorporated therein can be set to compensate 'for the increased pressures encountered at the lower floors. This enablesthe valve to operatev silently, quickly, positively, and economically at the different pressures encountered on the different floors without llO violent or agitated discharges from any valve and without subjectingthe valves to excessive wea-r or strain by reason of the higher pressures as encountered on the lower floors. f

The flow through port 28 is controlled by aV timing pin in the form of aVscrew 35, which is mounted in the boss in alignment with the port 28. The head of the screw is accessible from the exterior of the. housing 1 for adjustment by being located in a chamber 36 formed in the boss. .The chamber is closed by a removable cap 37 to protect the The screw extends through aV suitable packing 39 which is compressed between the inner end of ythe chamber 36 and the head of the screw, as shown in Fig. 1, so as to prevent leakage about the screw. The packing is so made that it conforms to the shape of the inner end of the chamber to make a tight joint and is resilient enough to be compressed by the screw in all adjusted positions thereof. To compress the packing, the screw has a pressure member 40 which' may be formed integral with the screw or constitute a separate part in the form of' a washer as shown. This construction provides a simple form of packing and avoids the expensive housing and packing arrangements as heretofore employed. Q

For operating the-auxiliary' valve 15 to relieve the pressure'in the chamber7 so that the mainA valve 6 may be opened by pressure on its under side, we provide a novel form of operating mechanism, as shown in Fig. 1. This `comprises a longitudinallyY movable plunger 41 slidably mounted in a tubular guide 42 carried by aboss 43 cast integral with the housing 1 and extending outward therefrom, as'shown. A union 44 is screwed on the outer end of the boss 43 and clamps the guide member 42 thereto. VAn oscillating handle 45 is supported by the union 44 and a coiled spring 46 in the union 44 normally maintains the outer end of the plunger 41 against the inner end of the handle 45 so that the plunger' will be moved inward b *thehandle in any direction that the handle may be oscillated. A cup nut 47Y is screwed on the inner end ofk the tubular guide 42 against a packing 48for' preventing water leaking out of the valve about the plung- At the inner end of the plunger 41 is a block 49 locatedV in the slot 23 and carrying a depressible pin 50 normally projected above the block by a coiled spring 51 surrounding the pin in a recess provided in the block for the pin, asshown in Fig. 1. The

vlower end of the spring 51 seats against a nut 52 screwed into the lower end of the recess and through which nut the in moves so as to be guided by the nut. he upper end of the spring engages under a shoulder der or enlargement 53 on the pin so as to reject the pin above the block lso that the pmvwill lstrike against the lower end ofthe lever 20 when the handle V45 is moved to openthe auxiliary valve 15. "The block 49 is prof 'is thereupon raised by the pressure on its under side to open the discharge side of the device to the intake' side 3. As the main valve 6 moves upward, the lever .20 is carried therewith out of contact with and above the pin 50, whereupon the lever 20 i's'free and the spring 18 closes the auxiliary valve 15 and swingsfthe lever 20 back into its normal valve-closing position. The pin 50 comes into contact with the lever 20 far enou h above its lower end to insure holding t e auxiliary valve 15 open for the greater portion or' the upward lmovement of the main valve 6, due to the 'fact that the lever does not trip off the'upperend of the pin until* just before the mainvalve-G reaches the limit of its upward movement. This necessitates substantiallyV the same discharge of li uids from the chamber 7 in each operation o the valve, and as a result a predetermined flush is obtained' at all times, because the period of time for the refill of the chamber 7 to automatically closey the vmain valve 6 is always the same.

In the closing movement of the main valve 6, the pin 50 will be in the path of downward movement of the lever 20 should the handle 45 be still held in valve-opening position. Vith the pin 50 depressible, -the main valvevmay still close without unseating the auxiliary valve 15 because the lever 20 as it is brought into contact with `the upper y `end of the pin 50 will depress it and allow the lmain valve to close without unseating theauxiliary valve. (See Fig. 4.) When the handle45 isreleased, the spring 46 will move the plunger 41 outward and carry the pin 5() from under the lowerv end of the lever 20, whereupon the spring 51 will immediately project thefpin 50 upward so asf to return it toits normal positionl for again opening the auxiliary valve upon the operation of the handle 45.

Vith this construction, it is apparent that the pin 50 will not interfere withor lprevent the closing of the main valve in any position of the pin 50 whether directl the vlever 20 therefrom. The slot-23 in the cylind'rie'guideA @not unor completely re'eased Cil only permits the pin 50 to reach thelever varm 20, but also permits the lever to swing 'without interference by the guide 9.A The vslot23 guides the block 49 and thus maintains the pin 50 in proper alignment with the lower end of the lever 2O by preventing .turning of the block with respect tothe plunger 4l. The slot 23 also permits the pin 59 to operate .through the cylindric guide 9 andvthus enables the height of the valve device to be materially reduced by loeating the parts closer to the main Vvalve, 6 thanY is possible when the parts are located beneath the lower end of the guide. This feature ,of reducing the height of the valve ldevicefis. also made possible by having the actuating mechanism for the auxiliary valve l5 operable between the ends of the guide 5,

which when disposed as in Fig. l is cored out on one side for Vthe purpose.

The upper ends Vof the webs l() of the .guide 9 terminate in an annular shoulder .55 against which the inner central portion ot the gasket l1 is clamped on screwing the guide intol the plate 6a. This maintains the gasket l1 tightly in the retainer l2 and prevents the gasket from warping or weaving through saturation, andi thus insures a perfeet seat for the main valve 6 in its closingv movement.

, Briefly, the valve device operates as follows. On operating the handle 45, the auX- iliary'V valve l5 is raised, relieving the .pres sure -`in chamber 7 so that the pressure on the intakevside of the valve will litt the main valve 6 off its seat and perm-it the flow to pass from intake 3 to discharge 4 through guide cylinder between the same and the .guide 9. As soon as the lowerend ot' the lever 2O is lifted from the pin 50, the spring 18 will close the auxiliary valve 15, whereupon the pressure in chamber 7 is again built up through by-pass 2G, Vand main valve 6 will be automatically closed. This returns the lever k20 to a posit-ion whereby it may again be opened by actuating the handle 45.

The valve device shown and described is simple Vin its construction, positive and quick in operation, and silent at all times, and permits a predetermined discharge of Vwater under all pressures, regardless of whetheixthe handle 45 is held open or closed for the auxiliary valve operable through the cylindric guide 9, the position of the operating mechanism may be brought more or less in the plane of the intake connection 3, thereby avoiding an oversized and ungainly structure as when the intake connection and the handle operating structure are in widely separated planes. y
