To all whom t may concern.-

Be it known that I, SAMUEL M. RHoADs, a citizen of the United States, residing in the city and county of Philadelphia,State of Pennsylvania, have invented a new and useful Improvement in Tapping Apparatus, which improvement is fully set forth in the following specification and accompanying drawings.

This in vention has reference to a novel construction of tapping apparatus, as will be hereinafter fully described and claimed.

Figure 1 represents a perspective View of a portion of the head of a barrel provided with a tapping apparatus embodying my invention. Fig.2 represents a vertical section thereof, taken on linex Fig. 3 represents a horizontal section taken on line fy y, Fig. 2. Fig. 4 represents a similar view with the parts shown in another position. Fig. 5 represents a vertical section of another embodiment of my invention. I l

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designatesa portion of the head of a barrel, and B my improved tapping apparatus. The latter comprises 'a plug or valve-seat C, secured within the head A, the same being provided with the conical socket D to form the seat for the valve E. The latter fits therein, the joint between the two being preferably ground, and is rotatably secured by means of a stem F at its 'lower end extending through an opening G in the bottom of the valve-seat D.

The valve E is provided with a port H, through which the pipe J is adapted to pass, and in the plug C is a port K, with which a port J is adapted to register when the valve is turned to one limit of its movement. The upper end of the port H is enlarged to form a'shoulder for a packing-ring L, that is adapted to be compressed upon the rod J by a gland M in an obvious manner. The openings N in the upper end of the valve E receive a suitable tool, by which it may be turned, the movement of which is limited by suitable stopsfor instance, a pin P, coacting with the shoulders Q at the upper edge of the plug C, as shown in Fig. l, said shoulders being so located that when the pin is in contact therewith the ports H and K register, as shown in Figs. 2 and 3, or are out of alinement, as shown inl Fig. 4.

For the purpose of admitting air or gas to the barrel to secure a pressure for dispensing its contents or, as is sometimes usual in connection with beer and the like, for charging the barrel with gas before it leaves the brewery I provide what I term a gas-valve R, rotatably mounted upon the valve E and operative independently thereof. This valve R is situated within a conical valve-seat S at one side of the valve E, being provided with a ground joint, and is secured by a downwardly-extending stem T, passing through and secured Within an opening U in the lower side of the valve E. A port V extends through the valve R, bein g enlarged and screw-threaded at its upper end to receive the gas or air 'pipe W, and when the valve R is turned this port V is thrown into or out of alinement with a port X, leading from the valve-seat S. The said valve R is provided with an opening Y,

so that it may be turned by a suitable tool.

The plug C is provided with two ports Z, With which the port X of the valve E registers when said valve E is turned to either limit of its movement.

The plug C may be provided with notches A', by means of which it can be screwed into the head of the barrel, and pivoted to one side of the plug O is a plate B to cover the valve when theliquid and gas or air pipes are not inserted, said plate B being provided with a lug C' to enter one of the notches A to hold said plate in place, the latter possessing suff icient resiliency to hold the lug in engagement therewith.

The operation is as follows: As shown in Fig. l, the shoulders Q are marked with the Words Off and On, and when the pin P is adjacent to the o-shoulder the ports H and K of the valve E and plug C are out of alinement, while the gas-valve R is situated over one of the ports Z of the plug C. By turning said gas-valve R to the point indicated OE on the top of the valve E it is evident that the barrel is entirely sealed. The port X in the bottom of the valve E registers with one of the ports Z when the valve is turned to either limit of its movement, and should it be desired to charge the barrel with gas in the IOO brewery, for instance, it will be necessary only to connect the pipe W, as shown in Fig. 2, and then turn the valve R to bring its port V into communication With the port X, which is attained by bringing the indicating-point on the top of the valve R opposite the word On on the top of the valve E. IVhen both valves are closed, the plate B is moved over the upper end thereof and is held in place by the lug C and the notch A.

In operating the tapping apparatus for dispensing, the tube J is first inserted through the washer L, and then the valve E is turned to cause the ports I-I and K to register. 'Then the tube .I is inserted to its full extent and the gland M tightened to com press the Washer upon said tube. The pipe W is then connected with the valve R, and when it is desired to obtain a pressure within the barrel said valve R is turned to cause the ports V and X to register, as Will be clearly understood.

In Fig. 5 I have shown another embodiment of my invention, in which the gas-valve R is dispensed with, and in lieu thereof a tube D is employed, which screws into the upper end of the port I-I in the valve E after the removal of the gland M. In the upper end of this tube D is a Washer E and a gland F to make a close joint with the tube G', it being noted that said tube G is smaller than the interior bore of the tube D/ to permit the passage of air or gas that enters this annular' space through a nozzle Il, provided with a valve J'. The operation of this device is somewhat similar to that heretofore described, it being noted that the tube G' is inserted through the Washer E' before the valve E is turned, While at the same time the valve J is closed. After the tube GH is inserted to its full extent and the Washer E compressed the valve J' can be operated at any time that it is desired to secure the pressure Within the barrel.

One ofthe advantages secured by my invention is due to the fact that the air or gas valve can remain closed when the beer-tube is first inserted and until the requisite pressure in the gas or air tube is secured, so as to avoid the entrance of beer or the like into the airtube, which occurs when the air-tube is first opened to the interior of the barrel if the reqnisite pressure has not been attained. With my invention, however, it is not necessary to open the gas or air valve until the desired pressure is secured.

ezinee Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a tapping apparatus, a valve, through which the liquid-tube is adapted to pass, provided With an independently-operative gasvalve.

2. In a tapping apparatus, a valve-seat provided with aport, a valve havinga port adapted to register therewith, a gas-valve carried by said valve, a port in said gas-valve adapted to register with a port in said valve, and a port in said Valve-seat adapted to register with the last-mentioned port in said Valve.

3. In a tapping apparatus, a valve-seat provided With a port, a valve having a port adapted to register therewith, a gas-valve carried by said valve and provided with a port, a port in said valve adapted to register with said port in the gas-valve, and ports in said valve-seat adapted to register with said lastmentioned port of the valve at either limitof the movement of the latter.

4. In a tapping apparatus, a valve-seat provided With a port, a valve provided with a port adapted to register therewith, the outer end of the port in said valve being provided with a Washer and gland, and a gas-valve carried by said valve and adapted to communicate with a port in said Valve-seat.

5. In a tapping apparatus, a valve-seat provided With shoulders, a port in said valveseat, a valve having a projection adapted to engage said shoulders, a port in said valve that registers with said port in the valve-seat when said projection is in engagement with one of said shoulders, and a gas-valve carried by said valve and adapted to communicate with a port in said valve-seat when said port of the valve is in communication with said first-mentioned port of the valve-seat.

6. In a tapping apparatus, a valve-seat provided with shoulders, a port in said valveseat, a valve having a projection adapted to engage said shoulders, a port in said valve that registers with said port in the valve-seat when said projection is in engagement with one of said shoulders, and a gas-valve carried by said valve and adapted to communicate with a port in said valve-seat, when said valve is at either limit of its movement.
