7 Claims. (Cl. 137-104) This invention relates to a supply fixture and more particularly the valve structure thereof and for toilet storage tanks.

This application is a division of the copending application, Serial No.- 284,432, filed July 14, 1939,

and entitled "Antisiphon, nonsplashing valve structure, and now Patent No. 2,229,601, granted Jan. 21, 1941.

The chief object of this invention is to provide a toilet storage tank fixture wherein the valve is of packless character and so arranged that it is substantially free from leakage, and especially free from splashing and squirting commonly characteristic of so-called packless valves.

The chief feature of this invention is to provide a valve structure arranged whereby water discharged under pressure creates a suction which is so associated with the packless valve member that leakage, as aforesaid, is eliminated and thus spraying or splashing of the storage tank cover does not occur.

Another feature of the invention is that a valve of this character shuts off at higher pressures than valves of this common characteristic employ.

Other objects and features of the invention will be set forth more fully hereinafter.

The full nature of the invention will be understood from the accompanying drawing, the following description and claims:

In the drawing, Fig. 1 is a front elevational view of the embodiment of the invention in association with a toilet tank arrangement, the latter being-shown in section and with cover removed.

Fig. 2 is an enlarged central sectional view of the invention and associated fixture parts.

Fig. 3 is a top plan view thereof.

In the drawing, l0 indicates a toilet storage tank. A pressure supply line II is suitably connected as at l2 to a riser structure 3, the latter extending through the tank l0 and being suitably sealed thereto as indicated at I3a. The upper end of the riser l3, see Fig. 2, is threaded as at I4 to receive a member l5 having an externally threaded portion l6 and a nozzle portion H, the latter terminating in a suitably formed end portion l8 which defines a discharge passage I9 that extends through the member l5 and'is in free communication with the riser l3.

A body portion 2|! having a chamber 2| adjacent the discharge nozzle l8 and surrounding the upwardly extending portion ll of the member I5 has threaded connection as at 22 with the 65 threaded portion l6 of the member is. This constitutes the support for the supply and control fixture.

The chamber 2| communicates with a superposed chamber 23 also formed in the member 20 and by means of a tapered passage 24. The up- 5 per end of the chamber 23 is closed by a plug or closure 25 having threaded engagement with the upper portion of the body casting and in axial alignment with the above described parts. This closure 25 terminates at its lower end ina frustol0 conical, preferably complementarily formedv portion 21. The seat 24 and valve portion 21, when properly spaced apart, provide a conically directed channel, providing a communication of regulated amount -between the chamber 2| and 15 the chamber 23, the regulation being obtainable as now set forth.

The outer end of the closure 25,-integral with the control valve 21, is provided with a lateral flange 28. The body portion includes a project- 20 ing flange 23, see Fig. 2, apertured as at 30 to receive a retaining bolt 3|, thehead of which overlies the flange 28 of the valve and closure member. This member 25-21 constitutes a closure for the chamber 23 together with a valve 25 member for controlling the communication between the chambers 2| and 23.

The member 25 has a bore 32 therein. This is of cylindrical character and slidably mounted therein is a valve member which is of packless 30 character. This valve member is of multi-part character. It includes a head portion 33 and a stem portion 35, the lower end of which is enlarged as at 35a. The stem and head portions have a threaded connection 33a therebetween, 35 see Fig. 2. The enlargement 35a is externally threaded as at 36 to receive a threaded sleeve 31 having an inwardly tapered flange 38. Between the body portion 2|]. 50

Included within said upwardly, and laterally directed portion 48 is a supply passage 49 which, at its lower end, communicates with the chamber 23 as shownin- Fig.2. The body portion of the member 25 herein is shown provided with ports I at It, the two ring or washer-like members being positioned in spaced relation and forming therebetween a chamber OI within the bore 32.

-The stem portion 35 oi the plunger is slidably supported in the apertures 02 and It, the ring members II and 03 being press fitted into the bore 32 and being relatively rigid'therewith.

I Now, when the lever 44 is actuated to elevate the plunger structure water under pressure discharges fmm the e it into the chamber 16 II. The majority of the water then discharg through the conical passage into the chamber 23 and then discharges upwardly through the passage I. Some of the water under pressure in chamber 2| will pass upwardly between the sleeve 31 and into the bore 32; and from thence it will pass through the lowermost ring member at the aperture 02 and into the bore chamber ll. Such water as does pass into this chamber 0 due to the discharge of water through passage ll is subject to suction applied to the ports II and thus the chamber 95 is a region of low pressure instead of being a region of high pressure such as chamber 2i. Consequently, little if any, water will discharge through the aperture 04 below the enlarged portion or head 33 of the plunger structure and within the member ll.

' Thus, the water will not spray or squirt upwardly because in most instances there will be no escape of water into this chamber last mentioned 35 and such that does or may escape will be under substantially little or no pressure and should any escape under slight pressure, it will immediately flow along the stem portion II and engage the under-face of the head 33 and thus be bailled or laterally directed.

The upper and remoteend of the passage I communicates with a chamber ill formed in an enlargement 5| integral with the upwardly directed portion I! of the body casting. Projecting fromthe enlargement ii is a pair of ears I! and the same pivotally support as at it a lever 55. This lever terminates in a threaded socket 58 adapted to receive an arm I! in the form of a rod, or the like, that threadedly supports a float 58. The lever between the connection 56 and the pivotal support 54 is connected to a dual link structure so connected together as at 60. This link structure is pivotally connected to the float mechanism as at I and is pivotally 55 connected as at 62 to an outer free end of the lever 44. i

Extending outwardly from the chamber II is a tubular portion "-see Fig. 1which supports a tube 64 that discharges into the overflow pipe 65 common to all toilet storage tanks. This overflow pipe discharges to the conduit 06 below the 'usual 'manual control "ball valve. The conduit 68 communicates freely with an intake structure fixture i1 normally. This fixture 61 65 is maintained in closed position by the rubber ball-like valve 68 carried by the lower end of the rod 69, slidably supported in the guide ll adjustably supported on the overflow pipe discharges to the conduit 06 below the usual manual 70 control ball valve. The conduit fl communicates freely with an intake structure fixture I normally. This fixture I1 is maintained in closed position by the rubber ball-like valve 08 carried by the lower end of the rod II, slidably I supported in the guide 10 adjustably supported on the overflow tube II as at H. An actuating. mechanism of conventional ,charactercommon to structures of this general type,.includes the lifter member I! and the head portion It of the rod ll bears on the lateral portion of said lifter 5 member.

It will be noted that as long as water is being supplied to the chamber 28 in regulated amount by means of the adjustment previously mentioned, water will discharge into the chamber I 10 and a relatively small amount of this water will discharge through tube It into the overfiow tube 6! and thence to the line It.

After the tank has been filled to the level indlcated by the dotted line determined by float 16 valve adjustment and the manual member is operated, the rubber ball valve is is elevated and the water discharges from the tank into the toilet bowl proper and flushes the bowl. In the event suchflushing syphons the water out of 20 the trap normally beyond or included in the bowl, the waterdischarged by line 64 into the overflow 05 upon closure of the valve 68, supplies water tothe bowl and especially the trap portion thereof to water seal the same. This 25 prevents the venting to the bowl of the undesirable odors that might be present in the waste pipepr line from the toilet fixture.

Another protective feature of the present invention is as follows: Should the pressure in the 80 1 supply line It be sufliciently greatin co-relation to the degree of opening between the conical member 2! and the seat 21 there is created a considerable degree of vacuum in the chamber OI so that air is drawn into the chamber through so the aperture N. g 1
