TOILET FLUSH TANK FLOAT VALVE Filed May 31, 1950 12a J0 INVENTOR.

' p In arezzaifibeizzeai $9 ATTORNEYS Patented June 3, 1952 TOILET FLUSH TANK FLOAT VALVE Samuel Monroe Bennett, Brighton, 0010. Application May 31, 1950, Serial No. 165,223

2 Claims.

This invention relates to float valves used primarily in flush tanks of toilet bowls, although it may be used for various purposes, and in particular flat disc of rubber or the like having a buoyant section mounted thereon and with the disc provided with an extension at one side by which it may be held in position over the end of a pipe or the like.

The purpose of this invention is to provide a float valve for closing open ends of vertically disposed pipes which is secured in position by the Weight of liquid in an enclosure and which, when opened, closes with a retarded action with the closure element floating downwardly with the liquid level in the tank.

Various attempts have been made to improve valves of flush tanks and the like to eliminate the inconvenience and waste caused by sticking valves and where positive operating valves are provided the cost thereof is prohibitive for general use. With this thought in mind this invention contemplates a method of forming a comparatively simple and inexpensive valve closure that remains in the position of closing the open end of a pipe until it is manually or mechanically opened and that is retained in the open position by a buoyant element until the liquid evel of an enclosure reaches the upper end of the pipe over which the valve is positioned.

The object of this invention is, therefore, to provide means for constructing a flapper action valve so that it may be used over open ends of pipes and wherein the valve automatically drops to the closed position as the liquid level in the enclosure on tank drops by the outflow of the water therein.

Another object of the invention is to provide a flapper action valve that may be incorporated in liquid containers and particularly flush tanks of toilet bowls now in use without changing the design or construction of the tanks.

A further object of the invention is to provide an improved flapper action valve for closing the upper ends of discharge pipes which is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a disc of rubber or other flexible material having a buoyant section secured thereto and having an extension at one side for anchoring the disc in operative position.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings wherein:

Figure 1 is a vertical section through a part of a flush tank of a toilet bowl showing the flapper action valve in the closed position on the discharge pipe of the tank.

Figure 2 is a similar view showing the valve in the open position.

Figure '3 is a plan view of the valve as shown in Figure 1 illustrating the valve anchored to an overflow pipe and positioned upon the end of a pipe.

Figure 4 is a view looking upwardly toward the under side of the valve shown in Figure 3.

Figure 5 is a perspective view illustrating the valve as shown in Figures 1 and 2 and showing the valve in the inverted position.

Referring now to the drawings wherein like reference characters denote corresponding parts the improved flapper action valve of this invention includes a disc ID of rubber or the like, a buoyant float section II secured to the under or top surface of the disc I0, an extension I2 formed at one side of the disc and provided with a hub or collar l3, and a flexible cord [4 or the like by which the disc is attached to a flush lever l5.

The disc Iii, which may be formed of rubber or other flexible material is positioned upon the upper end of an outwardly flared flange IS on the upper end of a discharge connection or drain pipe 11 and, with the parts positioned as illustrated in Figures 1 and 2 the hub [3 of the flexible disc, which is mounted in the extension I2, is positioned over an overflow pipe or tube I8, which extends upwardly from a side connection [9 of a fitting 20 that extends through an opening 2| in a bottom 22 of a tank 23. With the parts arranged in this manner the overflow pipe l8 provides anchoring means for retaining the disc III in operative position on the upper end of the flange l6 and as the flush tank is actuated by a lever 24 that is pivotally mounted in the tank 23 by a shaft 25 so that it moves the flushing lever l5 upwardly, the cord [4, which is attached to the lever l5 through one of the opening 26 at the upper end and to the disc [0 through an opening 29 therein at the lower end draws the disc to upwardly to the position shown in Figure 2.

After the valve has been actuated to the open position the buoyancy of the float I l holds the disc Ill upwardly until the liquid level drops to the position indicated by the upper dotted line as indicated by the numeral 38', in Figure 2-, and at this point the valve disc drops with the water until the disc rests upon the upper end of the section l6 at which time the water arrives at the lower level as indicated by the line 30 wherein the disc H) is positioned upon the upper edge of the flange l6.

The extension H! of the valve member I is provided with a centrally disposed opening 3! which provides arms 32 and 33 at the sides so that resiliency is obtained between the extension and disc.

The lower end of the cord M is attached to the 7 disc III by extending the cord through the opening 29 and forming a knot 34 in the lower end thereof. 'Ihe flush lever I- is pivotally mounted by a pin- 35" in a projection 36 on=one side of the tank 23.

With the parts arranged in this manner the:

'weight of liquid in the tank willhold the disc I0 upon the u p r edge of the muse re or the dis Charge pipe Hfland the disc will hold the: con

nection or pipe closed until it is moved upwardly from one edge of said valve member, resilient me'ar'iseonnecti-ng the valve member to the collar, saidcolla'r' adapted to be placed over the overflow tube for positioning the valve member on the drain pipe and adapted to frictionally grip said overflow tube for anchoring the valve member in operative position on the drain pipe, a float mounted on the under surface of said valve member and positioned in the drain pipe with the valve member resting upon the upper end of the pipe and means for actuating the valve member for'epefiing the drain pipe; from the ripper part of the tank 2. A one piece valve for use in toilet bowl flush tanks as described in claim 1 wherein the resilient means connecting the collar to the valve member comprises spaced arms of resilient material with cutout portions between the arms and said arms,. valve member, and collar being integr'al'.
