' (c1. 4-ss) This invention relates to means for preventing the sweating of a water closet flush tank and has special reference to suchmeans employing an inner tank which isheld in spaced relation to the .inner walls of the flush tank.
It is a generally accepted fact that sweating of azfiush tank may be eliminated by mounting r an inner liner or tank within the ordinary fiush "tank, and it. is well known that many patents have-been issued on devices employing this broad idea. 1 have come into general use. This is due, princi- However, none of these patented devices pally, to the fact that they are either too costly to manufacture or too expensive or inconvenient ,to install, and in some cases that the fittings are impractical. i
It is one of my principal objects to provide a fitting which will permit the installation of an inner tank within aifiush' tank in a simple and Another object is to provide a fitting which may be used in eitherold flush tanks or in new construction with equal efliciency and convenience;
Another object is to provide a fitting which may Several devices have been patented which ati tempt to drain oil the water which has dripped into the outer tank, however, here again, none of these devices have proven practical, and therefore it is another of my objects to provide ellicient means, in conjunction with my fitting, which will insure drainage of the water from between the tanks.
These and other objects and advantages will become more apparent as the description of the invention proceeds.
In the accompanying drawing forming a part of this application:
Fig. 1 is a vertical sectional view showing my invention installed in a closet flush tank.
Fig. 2 is an enlarged vertical sectional view of my improved fitting.
Fig. 3 is a broken bottom plan view of my fitting showing the drain channels.
Fig. 4 is a plan view of my spacer nut.
Fig. 5 is a side elevational view of Fig. 4.
In the drawing, the reference numeral l indicates a common china, or similar, flush tank, 2 indicates the usual water inlet valve and 3 the water pipe which commonly extends into the flush tank through the bottom thereof,

1 LUNlj'lED STATES PATENT OFFICE When installing an inner liner or tank 4, it
.is, of course, necessary to provide a spacer nut is deemed, needs no further explanation here.
However, it is in the flush valve seat fitting 6 where my improvement resides, and this iswhere prior devices have not proven successful. .My valve seat fitting is similar in general design to common valve seat fittings now in use in thatit provides a mounting for the overflow tube 1 in offset relation to the seat .8 for the ball valve 9, and has a threaded shank ID on which the mounting nut H is screwed to finish the water tight mounting of the, valve seat fitting in the closet.
In order to permit the installation of the inner liner tank 4 in spaced relation to the inner walls of the tank I, I have extended the length of the shank [0 to give ample room for spacing the liner from the tank as shown.
The valve seat fitting 6 is provided with a flange or collar [2 at the innermost end of the threads against which a gasket [3 is carried to insure a water tight assembly of the valve seat fitting 6 in the flush tank. A spacer. nut I4 is 7 screwed on to the shank 10 to secure the fitting in a water tight connection to the inner liner or tank 4, and also is of suitable thickness to space the bottom of the tank 4 from the bottom of the outer tank I.
The spacer nut has a plurality of bleeder ports I5 through the walls thereof, and the walls of the shank [0 are provided with a plurality of openings or ports l6 therethrough, preferably two as shown, the bleeder ports I5 and ports It: being in corresponding relation so that water which drips from the inner tank due to sweating or the like will drip into the outer tank and may drain from the outer tank into the water closet through the passage provided by the openings [5-46. It is deemed apparent that the bleeder ports may be laterally elongated as shown and so spaced that a through passage will be provided from the outer tank into the drain passage I! of the valve seat fitting 6 irrespective of the position to which the spacer nut I4 is tightened to seal the joint between the inner tank and the valve seat fitting.
In order to facilitate and augment the drainage of any water from the space between the inner and outer tanks I provide drain channels l8, preferably by casting walls IQ for same at the time the valve seat fitting 6 is cast. The walls IQ of the channels l8 are preferably arcuate in shape and relatively small in relation to the main drain channel I! of the valve seat fitting, the walls 19 being preferably hood-shaped at their upper end to close the upper end of the channel over the ports or openings Hi. This permits the water from the inner tank to flush through the passage I? with practically no resistance, yet provides a smooth drain channel from the space between the tanks.
As above set forth, this arrangement of channel l1 augments and facilitates the drainage of water from between the tanks, due principally, to the suction which is created in the channels 18 by the water from the inner tank as it flushes rapidly through the channel l1. "This'suction has considerable force and draws: water, standing between the tanks, through the bleeder ports l5, openings 16, andudrain channels 18, each time the closet is flushed, and therefore insures against any accumulationofwater between the "tanks which might causethe outer tank to sweat.
The inner tank 4 and valve seat fitting are se- -cured-in place-inthe outer tank I by means of the nut -l [,as above described and'the usual cone- "valve seat fitting, simply by not using the spacer shaped rubber washer 20- is employed to secure a water tight joint.
'-It is deemed apparentthat the instant valve seat fittingmay, if desired, beused as a common nut- M. This will place the-ports I6 below the level of the washer 2fl where they will have no *effect, and will'not interfere with the usual flush- -'ing action of the tank. This-featurewillpermit the manufacturing of-o'nly one fitting 6 to sup-' ply either of two uses, it-being deemed obvious that the preferred use is with the spacer nut and inner-tank.
