8 Claims.

My invention is concerned with dispensing apparatus for carbonated bottled liquids, and is designed to produce a device of the class described that can be cheaply manufactured, and that will be certain and eiiicient in its operation.

To illustrate my invention, I have annexed hereto a sheet of drawings, in which the same reference characters are used to designate identical parts in all the figures, of which,-

Fig. 1 is a central Vertical section of the cornplete apparatus;

Fig. 2 is a top plan View; and

Figs. 3, 4, and 5 are perspective views, in central vertical section, of the portions of the mechanism molded into the hard-rubber or similar base.

In carrying out my invention in its preferred form, I mold a preferably circular, bakelite base I0, which has at the center thereof and projecting upwardly therefrom the annular flange H forming a cup. .In a downwardly projecting boss I2 at the center thereof, I imbed, when it is molded, a metallic, preferably brass, plug I3, which has the top portion I4 preferably hexagonal in cross section, and with it and its lower portion internally threaded, as shown. In one side thereof is a circular aperture I5 in which fits the reduced end I6 of a horizontal tube I1 molded into the base and occupying the generally circular rib IB extending radially along the under side of the base. The other reduced end I8 of the tube II fits in a circular recess I9 formed in the plug 24, likewise molded in the base, and having its central hexagonal portion 2| ilush with the top of the base. The lower portion of the plug has the bore 22 therein, so that the top of the plug I3 is connected through the tube I'I with the top of the plug 20, which top has the beveled portion 23 producing a concavity which furnishes a seat for the rounded end 24 of the connecting piece 25, which has an annular shoulder 26 `to co-operate with the internally flanged, hexagonal nut 2l', which is screwed down on the threaded upper portion of the plug 2D so that its internal ange engages the flange 25 and secures the connecting piece 25 iirmly in place. In this connecting piece 25, there is placed the vertical delivery tube 28, which has threaded on its upper end the valve member 23, which has a valve seat 30 therein with which cooperates the valve 3l secured on the end of the vertically reciprocating valve stem 32, which has the push button 33 threaded on its upper end. A helically-coiled, expanding spring 34 secured in the enlarged upper end of the passage through (Cl. 225-2Z) the Valve member 29 engages the button 33 to hold the valve seated, and also engages the annular disk 35, which presses down on the packing 35 beneath it so as to prevent leakage. A spout member 31 extends from the central portion of the casting and has the outlet passage 38 therein leading to the discharge nipple 39 through which the liquid is delivered.

The plug I3 has at its upper end the small enlargement 40 of the bore, which enlargement furnishes the sharp edge 4I to co-operate with the tape-red portion 42 of the piercing member 43, which has its threaded lower end 44 screwed into the threaded upper end of the plug I3. Above the enlarged central portion of the piercing member 43 extends the spear head 45 shaped to puncture the tin cap of a bottle as it is thrust downwardly thereon. A passage 46 for the liquid extends upwardly thrcugh the piercing member to near its top, and an outlet for the same is formed by the two vertical slots 41 in the sides thereof above the annular seat 48 formed thereon. Above this seat is a small annular ilange 49 which engages the internally projecting annular flange 55 formed in the bottom opening of the soft-rubber, hollow ball 5I, the downwardly projecting annular bottom portion 52 of which rests on the hexagonal portion 2I of the plug 20. The ball 5I has the opening 53 in the top, through which extends the point of the cap-piercing member 43, and the material of the ball is preferably thinned out somewhat at the top so that, when a bottle is thrust downwardly thereon and the metallic cap is pierced, a liquid-tight connection will be maintained as long as the bottle is held in its downward position. The hollow space in the ball 5I enables the pressure of the liquid reacting against the interior of the ball to increase the effective pressure of its sealing surface against the bottle cap.

For this purpose, I provide on the top of the ring or cup I I holding mechanism as follows: On the top of the cup are three equi-distant lugs 54 having small internally-threaded brass tubes 55 molded therein, and between these lugs are three other equi-distant retaining lugs 55. Secured on top of the cup II by three screws 5l passed through the horizontal annular anged bottom 53 thereof is the guiding sleeve 59. In the space between the flange 59 and the top of the cup I I is placed the retaining spring 60, which, as best seen in Fig. 2, is made of a single piece of wire having the generally circular finger pieces 6I at the ends thereof, and the body portion of which is triangular, With the pair of curves 62 therein to pass CII around and engage two of the lugs 56. Three portions 63 of the Wire, as seen in Fig. 2, extend inside of the guiding sleeve 59, so that when a bottle is thrust downwardly thereinto, the neck, guided thereby, will bring the cap over the center of the piercing element, and the flange on the neck of the bottle will catch beneath the portions 63, which are spread apart in passing, and hold the bottle down. In this position, the piercing member is inside of the bottle, and the pressure of the gas in the bottle will force the liquid therein through the slots 4'! and the passage 4S and the tube Il, and so on, up through the tube 28 to the valve 3l, so that it can be delivered from the nozzle 39 merely by pressing the button 33 to open the valve.

While I have shown and described my invention as embodied in the form which I at present consider best adapted to carry out its purposes, it will be understood that it is capable of modication, and that I do not desire to be limited in the interpretation of the following claims except as may be necessitated by the state of the prior art.

What I claim as new, and desire to secure by Letters Patent of the United States, is:
