8 Claims.

This invention relates to an improved guide for guiding the movement of a rubber bulb type flush tank valve to and from an open and closed position and which will effectively function to insure a proper seating of the valve as it moves downwardly to a closed position and which will positively prevent the valve from seating incorrectly and thereby effectively preventing leakage between the valve and valve seat and thus eliminate the common operation of repeatedly lifting a iiush tank valve in an effort to cause it to seat properly and stop leakage from a flush tank and the noise which results therefrom.

Another object of the invention is to provide a Valve guide including a moveable guiding element which is urged downwardly by gravity above the valve and which will effectively function to guide the movement of the valve toward and away from the valve seat and will additionally function to urge the valve toward and into engagement with the valve seat to eliminate the common rattling sound frequently occurring with flush tank valves as they approach a seated or closed position,

A further object of the invention is to provide a valve guide capable of being detachabllr mounted on the overflow pipe of a standard or conventional flush valve and which is adjustable with respect thereto for properly positioning the guide relatively to the flush valve fitting and so that the flush valve will be correctly disposed to engage and close the seat of the flush valve tting when applied to the guide.

A further object of the invention is to provide a novel guide including a stationary guide portion and a moveable guide portion which is moveable with the valve toward and away from the valve seat and whereby the valve stem is guided at two longitudinally spaced points to insure correct movement of the valve directly toward and away from the valve seat.

Another object of the invention is to provide a fiush valve guide including a cage in which the valve is movably disposed and which cooperates with the valve seat to prevent .removal of the valve from the cage Without disassembling of the Cage.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, illustrating a presently preferred embodiment thereof, and wherein:

Figure l is a side elevational view, partly in vertical section showing a portion of a iiush tank equipped with a conventional flush Valve unit and showing the guide attached thereto in an applied and operative position;

Figure 2 is a perspective view of a portion of the guide shown applied to the stem of the ush valve, and

Figures 3 and 4 are horizontal sectional views taken substantially along planes as indicated by the lines 3-3 and 4 4, respectively, of Figure l.

Referring more specifically to the drawing, for the purpose of illustrating a preferred application and use of the flush tank valve guide, designated generally 5 and comprising the invention, a portion of the bottom S of a conventional flush tank or wate-r closet tank is illustrated in Figure l. The tank t3 is provided with an opening having a depending ange l. A standard flush valve fitting 8 has a depending threaded outlet 5! which extends downwardly through the flanged opening l and includes a collar I0 at its upper end which rests upon a sealing gasket II which seats in an internally flared upper portion I2 of the flanged opening l. A nut i3 threadedly engages the outlet Q and is advanced upwardly against a washer I4 which is clamped between said nut and the lower end of the annular flange l, so that when the nut I3 is tightened the gasket I I will be compressed between the collar I0 and the flared flange portion E2 to provide a liquid tight seal between the flanged opening I and the outlet 9. The upper end of a conduit I5 leading from the fitting 8 threadedly engages the outlet 9 belo-w the nut I3. The fitting S is provided with an upwardly facing valve seat II and includes a laterally extending tubular overflow connection Il disposed above the tank bottom t and which is provided with an upwardly extending overow pipe I8 which extends upwardly therefrom in laterally oifset relationship to the valve seat I6. Figure l also illustrates the lower portion i9 of a conventional valve operating rod having an eye Ztl disposed at a right angle to the axis thereof which slidably engages the upper portion of a valve stem 2I below an eye or enlargement 22, formed at the upper end of said stem 2l above the eye 20 and which is sufficiently large so that it may not pass through the eye 20. The opposite, lower end of the stern 2! is connected in a conventional manner to the upper end of a conventional rubber bulb type flush tank valve 23 the lower end of which is shaped to properly seat in and close the valve seat I6. The parts 6 to 23, previously described, constitute no part of the present invention but are conventional parts of a water closet tank and flush valve unit.

The valve guide 5, comprising the invention, includes a cage, designated generally 24, including a lower ring 25, an upper ring 26 and a plurality, preferably four, bars 2l extending between and connecting the rings 25 and 26 and which are preferably formed integral therewith. The bars 2 are channel shaped in cross section to denne inwardly facing guide channels 28. A pair of split clamps 2Q and 3G are secured to and project from the cage 2i, the upper clamp 29 being secured to the outer side of one of the bars 2l' and the lower clamp 3o being secured to the `lower portion of the same vbar 27 and to a portion of the bottom ring 25, said clamps 29 and Sti preferably being formed integral with-the case 24 and having split portions disposed remote thereto defined by outturned spaced apertured ears 3l, asbest seen in Figure 4, which are detachably connected by nut and bolt fastenings 32 associated with each of said clamps. It will be readily apparent that with the fastenings 32 loosened the clamps 29 and 3Q may be applied over the upper end of the overilow pipe I8 with the clamp 3@ disposed below `the clamp 29 and the axis of the cage 24 may then be positioned above and in alignment with the valve seat l 6, after which the fastenings -32 lmay be tightened for securing the clamps 2S and all to the overflow pipe la to thus rigidly secure the cage 24 in its correctly applied position of Figures l, 3 and 4.

The valve guide also includes a moveable guide member 33 which is substantially spider shaped and in the form of a cross having four equally spaced arms 34 extending. radially from a central or hub portion B5 thereof. The hub portion 35 is provided with a central guide opening 36. Each arm 33 is provided at its outer end with a runner 37 which is preferably formed i-ntegral with its respective arm 34 and which -connects therewith intermediate of the ends of the runner 3l. The runners 3l are disposed in upright positions perpendicular to the plane of the arms 34 and have inwardly `curved upper and lower end portions 38. The moveable guide member 3S is Sized to nt in the cage 24 and the runners 3l are each of a width to slidably t one of the guide channels 2B so that the moveable guide 33 is slidably disposed in the guide cage 2'4 and is or" suiiicient size so that the runners 3'! are retained against movement relatively to the cage 2f:- except longitudinally thereof, as clearly illustrated in Figures l and 4. Likewise, as illustrated in Figure l, the stein 42l extends loosely through the opening Sli of the moveable guide below the moveable guide 33 normally supports said guide with the central portion 35 thereof resting on the upper end of the valve 23. The opening is only sufcien'tly large to allow the stem 2l to slide therethrough and is of insufficient size to permit any lateral movement of the stem 2l and valve 23 relatively to the cage 24..

The valve guide li also includes a cap oroover 39 which ts over the upper ring 26 and has a top wall dil provided with a central opening 4l of substantially the same size as the opening 3l; and in alignment therewith through which another portion of the stem 2| slidably extends. The top wall 4Q is provided with a plurality of relatively large openings ^lil. disposed around and spaced from the opening 4i. A clamp 43 projects radially irom a peripheral portion of the member Si? and is disposed detachably on the overow pipe lil above the clamp 29. The clamp 43 corresponds to the clamps 29 and 33 and iis detachably clamped to the overflow pipe I8 :by

means of a nut and bolt fastening 44 for securing the member 39 on the upper end of the cage 24, after the valve 23 and moveable guide 33 has been positioned in the cage.

From the foregoing it will be readily apparent that when a conventional actuator, not shown, is operated to lift the rod portion IS, the said rod in moving upwardly will elevate the valve stein 2l and valve 23 due to engagement of the actuator eye 2E) with the enlargement 22 of the stem 2l, in a conventional manner. As the valve 23 moves upwardly to an open position, the moveable .guide 34 will be displaced upwardly with the valve 23 to maintainsaid valve in a position above and in alignment with the valve seat I6 so that after the water has escaped from the flush tank through the outlet 9 and the actuator I9 has returned to a lowered position, the valve 23 will move downwardly by gravity back to a properly seated position on the valve seat IHi for closing 4the .outlet of the fitting 8. It will also be apparent that the moveable guide S33 will vslide downwardly in the lcage 255 back to its position of Figure l as the valve 23 returns by gravity to .a vclosed position so that the valve stem 2l will be guided by the opening 4l of the member 39 and likewise by the moveable guide member ata point substantially below the stationary guide member 31! to insure proper seating of the valve 23 on the seat i 6, to prevent leakage through the fitting 8 and to prevent improper seating of the valve 23 which would permit leakage past the valve-seat i6. It will be readily apparent that water from the ush tank may pass through the open spaces of lthe cage between the fbars .Z'i' or beneath said cage to the outlet of the fitting d.

Various modications and changes are contemplated and may `.obviously be resorted to, without departing from the spirit or scope of the invention as hereinafter kdefined by the appended. claims.
