To (/,ZZ when?, it 717/047/ concer/L:
Be it known that I, IGNATZ Wassnnsrnon, of New York, in the county and State of New York, have invented a new and Improved Barrel-Tap, of which the following is a full, clear, and exact description.
This invention relates to tapping devices for barrels containing liquids under high pressure, such as beer, ale, and other fermented or distilled liquors; and the object is to provide a tap that will withstand a very high pressure, and in which the pressure will have a tendency to force the valve tightlyin its seat, thus preventing any possible leakage when the valve is closed.
I ,will describe a barrel-tap embodyingmy invention and then point out the novel fea tures in the appended claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a longitudinal section of a tap embodying my invention. Fig. 2 is an interior view looking toward the inner end of the valve. Fig. 3 is an interior view looking toward the outer end of the valve, and Fig. 4 is a longitudinal section showing the valve in its closing position.
The valve comprises a bushing, as here shown consisting of two sections 1 and 2, having a screw-thread engagement one with 1 the other, but it is obvious that this bushing may be made in one piece without departing from the spirit of my invention. The section 1 has an exterior screw-thread whereby it may be securely fastened in the bung-hole of a barrel.
Removably attached to the inner end of the bushing is a cap-piece 3, having a series of ports 4 for the discharge of liquid. The inner end of the section 2 of the bushing is provided With a beveled valve-seat 5, in which is mounted to rotate a correspondingly-shaped plug-valve 6. The smaller end of this tapered plug-valve, it will be seen, is toward the outer end of the bushing. Therefore the pressure of liquid on the outer end of said plug-valve will have a tendency to force the valve tightly into its seat.
To prevent displacement of the plug-valve 6, I employ a screw 7, which engages in a tapped hole in the cap 3 and impinges against the outer end of the plug-valve. At one side the valve G is provided with a port 8, which extends from a communication with the interior of the cap and is adapted for com munication with a port 9, formed in the wall of the valve-seat and having communication with the interior of said bushing. The opposite side of the valve Gis provided with a port 10, extended from the interior of the bushing and adapted for connection with a port 11, formed in the wall of the valve-seat and having communication with the interior of the cap 8.
It will be seen that the ports S and 10 extend, respectively, from opposite ends of the plug-valve and terminate intermediate of the ends of the valve, and that the ports 9 and 11 extend from opposite ends of the valve-seat and terminate intermediate of the ends thereof. By turning the plug-valve to the position shown in Fi g.l the liquid may iow outthrough the ports 8, 9, 11, and 10 and enter a tubular Vkey 12, having ports 13 through its wall within the bushing.
From the inner end of the plu g-valve 6 a lug 14 extends inward. This lug 14 is made anguiar in crosssection, to be engaged by the correspondingly-shaped end of the tubular key 12. This key 12 has an enlarged portion 15, designed to engage in the outer end of the bushing, and it is provided with opposite wings 1G, which may pass through opposite recesses 17, and when the key is turned may engage against the interior flange portions 1S of the bushing and thus secure the key in place.
Mounted on the tubular key 12 and bearing against the inner end of the enlarged portion 15 is a washer 19, of yielding mate1ial-such, for instance, as rubber-and designed to engage against an annular flange 20 within the bushing. The outer end of the key 12 is provided with a screw-thread 21 to be engaged with a coupling for a pipe leading to a dischargeiaucet.
In operation, when the key is inserted and its inner end engaged with the lug 14, upon turning the key the ports 8 and 9 will be put into communication and the ports 10 and 11 will also be put in communication. Upon turning the key in the opposite direction to IOO remove it from the bushing the ports will of course be turned out of alineinent.
Having thus described my invention, I claim as newr and desire to secure by Letters Patent- 1. A barrel-tap, comprising a bushing de? signed to be engaged i-n the bung-hole of a barrel, a tapered valve-seat in the inner end of said bushing and having ports in its opposite sides extended respectively from opposite ends of said valve-seat to a point intermediate of its ends, a plug-valve mounted to r0- tate in said valve-seat and having ports in its opposite sides extended respectively from opposite ends to points intermediate of the ends, a perforated cap on the inner end of the bushing, and a key for turning the valve, substantially as specified.
2. A barrel-tap, comprising a bushing having a tapered valve-seat in its inner end provided With opposite ports, the said ports being extended respectively from opposite ends of the valve-seat and terminating at points intermediate of the ends, a tapered plug-valve mounted to rotate in the valve-seat and provided With opposite ports respectively extended from opposite ends of the plug-valve to points intermediate of its ends, the smaller end of said plug-valve being toward the outer end of the bushing, a perforated cap-piece having Screw-thread engagement With the inner end of the bushing, a screwr engaging in a tapped hole in said cap-piece and impinging upon the plug-valve, a lug extended from the smaller en d of the plug-valve, the said lug being angular in cross-section, and a tubular tnrning-key-for engaging with said lng, suhstantially as specified.
