TAP FOB DISPENSING LIQUID UNDER PRESSURE.

Specification of Letters Patent.

Patented May 9, 1911.

T 0 all whom it may concern:

Be it known that I, GUY L. KENNEDY, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Taps for Dispensing Liquidsunder Pressure, of which the following is a specification.

The object of the present invention is to provide a simple, cheap, and convenient tap, which can be applied or attached to siphon bottles containing aerated liquids, for the purpose of discharging from the bottle any desired portion of the contents thereof.

The invention is intended to be used in combination with siphon bottles, provided with an improved head, theconstruction of which forms the subject of a. separate application filed herewith. Aerated liquids of any kind may be supplied in siphon bottles having these heads and my improved tap may be applied to any one of the bottles for dispensing any desired part of the liquid therefrom, and, upon withdrawingthe tap, the remainder of the liquid will remain perfectly aerated, until the entire 'amount of the liquid has been withdrawn.

In the accompanying-drawing, the figure is a side view of a bottle to which my invention is shown as being applied, the tap itself and the stopper for the bottle being shown in section;

Referring to the drawing l indicates a,

casing, closed at'its rear end by 'a cap 2, and its-main body being cylindrical in form and having a taperingfdischarge spout 3, the passage of which is'contracted at its inner end, as shown at 4, the wall of said contracted portion being extended to form a valve seat 5. Against said valve seat is normally pressed a rubber faced valve 6, secured to the end of a valve stem 8. Secured ,upon said stem 8 is a disk 10, which forms a guide for said stem within said casing, and

approximately in the middle of its length,

which, as hereinafter described,-forms a fulbodying the same principle of construction,

and, in the form herein shown, the upper end of the neck of the bottle is formed with an outwardly extended flange 16, upon which rests the flange 17 of a conoidal metallic siphon head 18, the .lowerend of which isconnected to the upper end of a siphon tube 19, de ending into the bottle. Upon said flange 17 rests a circular flange 20 of a check valve 21, of soft rubber. Said flanges 17 and 20 are clamped between the flange 16' and a cap 22, centrally apertured, as shown at 26, the inner surface of the ,cvlindrical portion of which cap is threaded and is screwed on to a collar 23 surrounding the neck of the bottle. Said check valve comprises, in audition to said flange 20, a hollow conoidal shell 27 of rubber of considerable thickness, and the apex of said conoidal portion is transversely slitted, as shown at 28. The lips of said slit are normally, and

unless thrust apart, in contact with each other, so as to absolutely prevent the escape of any gas from the siphon bottle.

In use, the bottles closed by these stoppers are filled with any desired aerated liquid, and when it is desired to withdraw any quantity of liquid from any one of the bottles, the depending tube 19 is inserted through the central hole 26 in the cap 22, and is pushed down in the middle of the conoidal shell 27 until its lower end enters the slit 28 in the apex of said shell, causing its lips to diverge, and opening communication between the siphon bottle and the valve chamber. In this osition the bend 25 rests against the cylindrical surface of the cap in whatever angular position of the tap, relative to the bottle, the depending tube has been inserted. The operator now presses inward the lower end of. said lever 14, thereby rocking the same upon its fulcrum 25 and withdrawing the valve 6 from its seat against the action of the spring 11, thereby opening free compermitting the valve to close,

immediately 2 bottle in succession, as

munication between the siphon bottle and the discharge spout. When a sufficient quantity of the liquld has been withdrawn, the operator removes the pressure from the lever,

and then withdraws the tap from connection with the cap, whereupon'the slit in the check valve closes, escape of the aerated liquid from, the siphon bottle.

It will be observed that the arrangement insures the insertion of the tube into the check valve far. enough to open said check valve for it is only when the tube 15 15 18 inserted a suliicient distance that the lever preventing any further readily apprehended from the foregoing descriptlon.

I clann sure comprising a valve casing, a valve therein, a spring for normally closing said valve, :1 tube extending laterally from said valve casing and adapted to be passed centrally through a central cap of a vessel containing liquid under a check valve therein, and a lever, one end of which is operatively connected to said valve, and formed with abend, which when said tube is thus inserted to open said check valve contacts with the cylindrical surface of said cap to form a fulcrum, substantially as described.

In testimony my hand in the witnesses.

whereof I have hereunto set presence of two subscribing GUY L. KENNEDY.
