LEAKPROOF VALVE Filed Jan. 1 8. 194.0y

71' Tae/vaas Patented Mar. 25, 1941 UNITED STATES PATENT OFFICE 1 claim.

It is a well known fact `that valves are among the most important elements of industry in general, and it is also known that every type of known valve today will leak more or less, and which has caused a great deal of difficulty.

One of the objects of this invention is to produce a valve construction that is entirely new and that is positively leak-proof.

Another advantage of the invention is the fact that there are no moving parts which are subject to wear and causing them to leak.

While the invention is primarily designed so as to accommodate beer lines, it is no less advantageous as applied for Water and other liquids, or for air.

With the foregoing in mind, it will become readily apparent that the invention possesses further advantages, all of which will be clearly revealed during the course of the following detailed description, illustrated throughout the accompanying drawing, and more fully pointed out in the appended claim.

With reference to the drawing:

Figure 1 is a top plan View of the complete invention; and Figure 2 is a side elevation thereof.

Figure 3 is an enlarged sectional assembly taken through the longitudinal center thereof.

Figure 4 is a top plan view of the bowl element of the device; and Figure 5 is a side elevation thereof.

Figure 6 is a side elevation of the stem member.

Figure 7 is a top plan View of the cap member; and Figure 8 is a side elevation thereof.

Figure 9 is a top plan View of the disc member; and Figure 10 is a side elevation thereof.

Figure 1l is a top plan `View of the diaphragm; and Figure 12 is a side elevation thereof.

The invention comprises a body that is composed of a suitable metal and having bowl I. A portion of one end of bowl I is extended tubular portion 2 which is adapted to connect to a beer barrel, and the opposite portion is extended and forming inclosed end 3 as shown.

Tubular portion 4 is depended downwardly from bowl I and is adapted to threadedly engage a pipe line to the beer coils.

With particular reference to Figure 3 the complete valve construction is indicated as in an open position.

Cap 5 is provided and is adapted to threadedly engage bowl I, and it is seen that a portion of said cap is extended upwardly and forming thereby hexagon nut 6, and in the center of the cap is threadedopening I so as to similarly engage stem 8, and said stem having hand-hold 9 where shown.

Still referring to Figure 3, it is seen that oating disc I0 is provided and has flanged edge II as shown, also similar flanged portion I2 upon 5 the inside of cap 5. The purpose of portions II and I2 is to prevent disc I0 from falling out of cap 5 when the same is removed from bowl I.

Bowl I is provided with inner seat I3 so as to accommodate flexible rubber washer I4 and metal 10 diaphragm l5 as shown.

The purpose of disc I0 is to prevent wear upon diaphragm I5, as when stem 8 is pressed upon said disc, the disc firmly presses the diaphragm. In this manner frictional wear between these elel5 ments is eliminated.

Tubular por-tion 4 is provided with circumferential raised flange I6 at the upper end thereof, providing an enlarged beer collecting chamber around the upper end of the outlet port 4, and the valve is closed by threadedly lowering stem 8 upon disc I0 thus forcing diaphragm I5 downwardly upon ilange I6 and in this manner passage between tubular portions 2 and 4 is closed. The valve is likewise opened by threadedly back- 25 ing stem 8 thus releasing pressure upon disc Ill and diaphragm I5.

The diaphragm I5 is held seatedonly against the top of the outlet port 4 so that the beer flowing into the chamber under low pressure will accumulate in the chamber and present sufficient pressure, even though low, against the bottom face of the diaphragm to cause the latter to positively and uniformly move upward to unseat the outlet port when the threaded stem .8 is y moved upwardly and disengaged from the upper face of the floating disc.

As previously stated, the principle of this invention is well adapted for use as an air valve, or'for water and other liquids.

In conclusion, let it be understood that the complete disclosure herewith is merely illustrative of the general principle of the invention sought to be protected by Letters Patent, and that any contemplated change made therein would fall directly within the scope of the claim.

Having thus fully described my invention, what I claim as new is:

In a valve structure, a body including an enlarged bowl, an inlet port leading into the bottom of the bowl at one side thereof, a centrally disposed outlet port extending downwardly from the bottom of the bowl, the upper end of the outletl port projecting above the bottom of the bowl, a diaphragm arranged in the bowl, a cap member detachably secured in the upper portion of the bowl, the bottom face of thecap member having a pocket formed therein, a. anged disc loosely mounted for vertical movement in said pocket, means at the outer face of the pocket to pre- Vent disengagement of the disc from the pocket, the bottom face of the disc contacting the upper face of the diaphragm, and a stem threaded through the top of the cap member and extending into the pocket for engagement with the upper face of 4the disc to force the central portion of the diaphragm into sealing engagement with 5 the projected upper end of the outlet port.
