Figure 14 is a' modification of the valve means 5 shown in Figure 3, illustrating in detail the variation of the valve chamber. I

Referring to Figures 1 and 3, the valve head I is formed with an inner cylindrical valve chamber 2 and outlet 3, including the tubular spigot mem- I her 4. E

The valve head I is further formed to include the liquid inlet chamber 5 connecting the valvechamber 2 with the source of liquid. As shownin Figure 3 the inlet chamber 5 is slightly larger in diameter than the valve chamber 2, the connecting wall being recessed to form a socket for ball Gas a closure to the valve chamber 2, and lrairevgnting access of liquid from the inlet cham- The ball closure 6 is normally retained in the socket, thus formed, by the spring I which rests upon the top surface of the tube l4 and is held in position by the bushing 8, as shown in Figure 3.

The rod 9 extends through the vertical bore I0 in the valve head I and contacts the ball closure 6, as shown in Figure 3. The pin II is aiiixed at the base of the rod-9, retaining it in position in the bore Hi, the button I2 forming a convenient means for exerting pressure on the rod 9. 0

In Figures 1 and 2 I have shown a rounded knob I 3 afiixed to and as a feature of the valve head I, as a convenience in exerting pressure on" the device, said knob having a recess in the top thereof to receive the button l2. 7

Referring to Figure 14, I have shown a variation in the features of the valve illustrated in Figure 3, which it may be found advisableto use under certain conditions. The valve chamber 2 is formed to-allow a greater surface of contact of the liquid with the top of said chamber.

The connection of the siphon tube II with the valve head is shown in Figure 3, being threaded into the bushing 8 to form the connection with the valve head I.

The siphon tube ll tapers slightly from its connection with the valve head toward its free end, the circular punch and cutting device 15 being secured to the base of the said tube by threading, welding, or by other conventional means. As shown in Figure 1 the side surface of the cutter is flush with the surface of the siphon tube l4.

The details of the punch and cutter edge l5 are shown in Figures 9, 10, and 11, comprising a bifurcated cutting edge, the parts formed by such bifurcation being pointed, as shown. To increase the flow of liquid through said punch and tube l4 after perforation of the can or crown a side exit connecting the tubular interior of the punch with the exterior thereof may be used, as

shown in Figures 9 and 11.

As it is not desired that the metal be entirely separated from the crown or can upon punching the aperture therein the apex on one side of the bifurcated cutter is extended beyond the plane of the opposing apex and is rounded, with the groove [6 added, as shown in Figures 10 and 11.

By this arrangement the circular piece of metal is severed from the crown or can, excepting for that portion coming in contact with the rounded edge in the longer crotch and which causes the metal so cut from the aperture to be curled as shown in Figures 12 and 13, the groove ii of the cutter assisting in this operation.

Especially for use of my device on crown-sealed bottles, I have provided a means for facilitating its operation through the clamp illustrated in Figures 1 and 2, the details of which are shown in Figures 4, 5, 6, 7, and 8.

With reference to these figures, the bottle cover means I! is formed as shown in Figure 4 to fit over the crown cap on the bottle. The washer I! of any suitable resilient material is used to effect a close contact with the 'crown cap and the tube i4, and to allow uniformapplication of the device notwithstanding variations in the height of the crown finish on bottles. Through the tubular sleeve is is inserted the siphon tube ,enabling vertical movement of the cover means and its appendages on such tube.

The angular channel is rigidly amxed, such as by welding, to the exterior side wall of cover member II, to receive the upright shaft 2| which is integral with and extending at a 90 angle from the collar member 22, thus forming means whereby such collar member 22 is kept in alignment with the cover member i1, and at the same time is allowed vertical movement to the extent of that portion of the shaft 2| intermediate the cross pin 23 and the free end of said shaft.

Pending actual clamping on the bottle head, the collar member 22 is retained on the bottle neck below the crown finish by means of the spring member 24 which is embedded in and held by the peripheral groove 25 in such collar member.

The vertical movement of the collar member 22 is accomplished by means of duplicate wire link members 26, in pivots 21 on opposite sides of cover member I1, as shown in Figures 1 and 5. Such wire link members 22 are pivoted at the opposite ends thereof in corresponding loops 28 which are placed on either side of the collar member 22 and are integral with the wire lever member 29, the free ends of which are fixed in pivots 30 on opposite sides of the collar member 22.

In explanation of the operation of my device, and referring to Figures 1 and 2, by placing the punch and cutting member I! on the closure to be penetrated and exerting pressure downward on the knob l3 the aperture similar to that shown in Figure 12 is made and the siphon tube [4 inserted to the desired depth. Because of the taper of the siphon tube l4 increasing pressure is exerted on the periphery of said aperture as the tube i4 is inserted and thus forms an effective seal against the escape of pressure or liquid from the container except through said tube.

If the container is a. bottle sealed with the usual type of crown cap the operation involves the use of the clamping device feature of my invention, as shown in Figure 2, and explained as follows:

With the clamping device comprising the cover member l1, collar member 22 and connecting members, in the open position shown in Figure l, and prior to insertion of siphon tube ll in the sleeve IS, the bottle neck is forced between the opposing ends of the spring member 24 in the collar member 22, securing the neck inside said collar with the crown on the top of the bottle opposing washer l8 in the cover member I].

Downward pressure on the lever 29, locking it in the position shown in Figure 2, causes a vertical movement of the collar 22 and its upright shaft 2i, the top surface of the collar member 22 i being held against the reenforcing ring on the bottle top, while the cover member I! through its washer I8 is compressed against the surface of the. bottle cap and the tube It. In this way accidental removal of the crown cap through increased internal pressure in the bottle is prevented, the close contact of the washer IS with the crown cap and the tube creates an additional safeguard against pressure leakage from within the bottle, and the rigid position thus assumed by the sleeve l9 provides a substantial guide means for inserting the tube member i4 through the crown cap as hereinbefore explained as well as an additional safeguard against leakage from the bottle.

Referring to Figures 1 and 2, the washer 3| of resilient material is afllxed on the tube I4 at the base of the siphon head. When the siphon tube I4 is inserted through the sleeve is into the bottle the pressure between the siphon head and said sleeve l9 com'pressesthe washer 3| which there,- by provides an additional safeguard against leakage.

In tapping somev containers it may be found inadvisable to use the clamping device comprising the sleeve l9, cover [1, and collar 22, in which event those members may be removed from the tube before it is inserted into the container. Then by pushing the tube l4 into the container until the washer 3i rests upon the container surface and is compressed between such surface and the siphon head, aided by the increasing pressure against the edge of the aperture by the increasing diameter of the tube ll as it is forced through the container surface. an efllclent seal against liquid or pressure leakage is also'provided.

Referring to Figures 2 and 3, when the siphon tube II has been inserted into the container from which the charged liquid is to be drawn and is in operating position, the spring I aided by the internal pressure retains the ball closure 6 in closed position and prevents exit of the liquid through the siphon head. Upon downward pressure on the button l2 and rod 9 the ball 6 is unseated and the internal pressure in the container forces the liquid upwardly through the tube ll, liquid in let chamber 5, valve chamber 2. and liquid exit 3. Upon release of the pressure on the rod 5, the ball spoons:

O is automatically returned to its closed position and shuts oil further exit of the charged liquid.

Removal of the device from the container is accomplished by reversing the operation described above. Upward force exerted on the knot 53 will withdraw the tube from the container. The clamp member comprising the cover ii and collar 22 is then removed by the upward movement of the lever 29, thus releasing them from their impinging contact with the bottle crown and reeniorcing ring of the bottle top.
