` l WATER CONTROL FOR CLOSET TANKS Filed Feb. 1e, 1942 Patented Oct. 20, 19.42

UNITED 'a STATES PATENT OFFICE wam comer. ron cnosa'r 'rms nennen svlrsky, Glendale, cam. Application February 16, 1942, Serial No. 431,017 4 claims. (c1. lav- 194) 'I his invention relates to improved means for controlling water in closet tanks.

Important objects of the invention are: To provide an improved toilet storage tank and ball cock fixture combination; to provide improved means for silencing the water during its depart ture from the ball cock structure into the tank; to provide an improved ball cock fixture per se; to provide improved means for independently preventing anti-syphoningof the water in the storage tank through the re-flll tube or the ball cock valve structure into the main supply line and contaminating the same; to provide in a ball cock iixture an improved valve and valve seat structure; and to in general improve upon and reduce the number of parts entering into the combinationl of elements comprising the ball cock structure thereby not only increasing the elllciency of the device as a whole, but also rendering` less costly the manufacture of the different elements and the labor involved in assembling them. ,f Other objects, advantages and features of invention will hereinafter appear.

Referring to the drawing wherein is shwn a preferred embodiment of the invention as now reduced to practice:

Fig. 1 is a cross section of a' toilet tank showing the installed device ln a position for flushing.

Fig. 2 is an enlarged view partly in side elevation and partly in vertical midsection of the ball cock structure per se shown in Fig. 1, some portions being broken away in order to contract the view. l

Fig. 3 is a transverse section taken on line 3-3 of Fig. 2, a portion of the re-iill tube being included in the view.

Referring in detail to the briefly described views, the numeral I indicates a toilet tank containing a body of water 5 which is discharged through the fixture 8 in a ldirection indicated by the arrow when the valve 1 is operated by means of a conventional trip lever through the medium of the lift 8 in the well known manner.- An overflow pipe 9 connects with the ilxture' at a lower level than the seat of the valve 1 and into the mouth of said pipe is directed the free end of the re-flll tube I0, the mouth of said tube being located preferably above the highest level of the body of water in the tank. y

A pressure source of water supply communicates with the tank 4, it being connected to the inlet pipe I I and the latter pipe being sealed with the floor ofthe vtank by meansl of the gasket washer I2. Into the annular recess Ilr located in the discharge end of the pipe II is sweated the contracted lower end of the tubular valve cup I 3, the outer diameter of said cup above said contraction being the same as that of the pipe Il and thev upper part of said cup being externally screwthreaded and having screwed thereonto the tubular cap structure Il.

The valve cup I3 is provided with a threaded inlet port I 5 in the transversely extending bottom portion thereof in axial alinement with the pipe Il and into said port is screwed a tubular screw I6, by means of which the valve seat gasket washer I1 is secured to the bottom of the cup. In the wall of the cup I3 at a point slightly spaced above its point of sweating onto the pipe II is arranged a circumferentlally spaced series of radially extending passages I8.

The cap structure I4 at a point adjacent its threaded union with the cup I3 is outwardly bulged thereby providing a semi-circularly shaped, circumferential passageway I 8 into which the water discharges from the passages l8-and below said passageway said bulge terminates in a downwardly directed skirt 20 the inner periphery v tically slidable plunger valve 25, the upper part of which has a working fit within the tubular cap extension I4. The lower portion of the plunger valve 25 which remains within the valve cup I3 during the operation of the device has a diametrically enlarged part 26 which forms an annular extension or broad circumferential rib therearound, this enlarged part having acylindrical face that has a working t within the valve cup I3. During the operation of the device the enlarged p-art 26 always remains above the passages I8.

The lower end of the plunger valve 25 has a central concavity 21 and around sa-id concavity a bevel 28, thus providing a definite circular edge for contacting with the valve washer I 1 when the valve closes. 'Ihe concave recess 21 extends into the end of the plunger a sufllcient distance safely to clear the head of the tubular screws I6 Awhen the plunger valve is in the seated position.

At one side, on a level with its annular chanstitutes the subject matter oi a copendingfapplication Serial No. 446,726,- nled June l2, i942.

The upper part ci the tubular cap structure is provided with conventional oppositely disposedy extensions il and i2 to which are respectively pivoted the float rod da and lever da, the pivoted portions of said rod and lever being biiurcated so as to straddle the upper portions of said two extensions. The rod structure i3 carries aoat l5 on one end and at its opposite end has biiurcations between which are pivoted the anti friction roller @E which normally rests upon the free end of the lever iid. A regulating screw di, carried by the mid-length portion of said lever dii has its headed end directed upwardly and its lower end normally resting upon the top of the plunger valve 25.

Around the inlet pipe is loosely fitted a float 5l, by preference and as shown consisting of a thick round wooden washer or disk. This iioat is so positioned as to have the water issuing from the annular outlet channel 2i directed downwardly upon its upper surface, thus silencing the noise produced by the downward stream of water issing from the annular passage 2i. The buoyant body 5i rises and fallswith the Water level and its upper surface is always in the path of said downward stream. The force of this stream may slightly submerge said body at times. Said buoyant body will always function to cause said downward stream of water to merge in a noiseless manner with the body of water in the tank.

In the operation of the device the toilet tank 4 is flushed in the well known manner, at which time the valve controlling float means 45 drops as the body of water 5 in said tank is emptied through the discharge iitting 6. As the globular :iloat 45 starts to fall the inlet means controlled by the plunger is immediately opened and water from the supply pipe il starts iowing through the radial passages `i8 into the passageway i9 and through the annular channel 2l into the tank. -As the water leaves the annular channel 2i it is directed against the annular float 5I during the time the tank is emptying, and While the tank is filling the annular float rises, always maintaining a buoyant position, so that the water falling thereagainst will merge with the water in the tank without noise. Y

As a portion of the water flows through the channel 2i into the tank, other parts of the stream are directed through the lateral extension 3l through the reduced passage 33, across the gap 34 into the terminal passage 35 and thence through the re-fll tube lil into the overflow pipe 9 for the well known purpose. The air gap 34 prevents water at any time from being syphoned through the re-nll tube into the main supply line.

The operation of the remaining structure, not specically alluded to, will be readily understood from the preceding detailed description.

It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modications and equivalents which fall within the scope of the subject matter claimed.

What is claimed is:

l. The combination, with the flushing tank of a toilet and an upstanding supply pipe in said tank; of a :lioat controlled inlet valve structure4 mounted upon said pipe, said structure including a tubular valve casing and a plunger valve vertically slidaole therein to and from a position wherein its lower end engages a valve seat in said casing, an outer tubular member surrounding said valve casing and having an interior circumi'erential recess forming a channel therearound, said valve casing having outlet ports communieating with said channel and said outer tubular rnember having a skirt portion in a surrounding outwardly spaced relation to said pipe thus aiiording a downwardly directed annular outlet channel leading from the rst recited channel, and a silencing means rising and falling with the water level in said tank surrounding said pipe in a position for the water issuing from said downwardly directed channel to strike against.

2. In a valve structure, an upstanding pipe vhaving an internal shoulder adjacent to its upper end, a cup shaped member fitted within the upper part of said pipe and resting upon said shoulder, said member having a bottom aperture, a, valve seat gasket washer overlying the bottom of said cup around said aperture, a tubular screw screwed into said aperture and having a head which retains said washer in place, a plunger valve verend portion of said plunger valve being diametrically contracted thereby providing around it an annular chamber within the cup which communicates with the aforesaid outlet means.

4. The combination, with the flushing tank of a toilet and an upstanding supply pipe in said tank; of a float controlled inlet valve structure mounted upon said pipe, said structure including a tubular valve casing and a plunger valve ventically slidable therein to and from a position wherein its lower end engages a valve seat therein, an outer tubular member surrounding said valve casing and having an interior circumferential recess forming a channel therearound, said valve casing having outlet ports communicating with said channel and said outer tubular member having a skirt portion in a surrounding outwardly spaced relation to said pipe thus affording a downwardly directed annular outlet channel leading from the rst recited channel, and a silencing means surrounding said pipe in a position for the water issuing from said downwardly directed channel to strike against, said silencing means consisting of a buoyant body having an apertured portion loosely surrounding said pipe.
