11 Claims.

This invention relates in general to dispensers for liquid, particularly carbonated beverages such as beer.

One of the objects of the invention is to provide a dispenser of this character which makes it practical, convenient, economical and safe to utilize carbon dioxide for maintaining the proper carbonation of and the proper head of pressure on the beer. These advantages are realized to such an extent as to render the device available is provided and is equipped with a dispensing faucet. Surmounting the faucet and connected with the tap rod is a fitting which provides for the mounting of a gage and for the support and connection to the tap rod of a cartridge or holder for a supply of gas under pressure. In the releasable connection provided between the discharge nipple of the cartridge and the fitting, novel features are embodied which provide for hermetic sealing of the connection and also for the automatic undersetting of the valve in the discharge nipple of the cartridge. The discharge nipple of the cartridge and the associated parts are protected against breakage or the application of excessive strain by a suitable guard which takes the form of a tubular structure telescoped over the adjacent vend of the cartridge, interconnecting with the-fitting and straddling the connection and the nipple.

l Other objects and advantages reside in lcertain novel features of the construction, arrangement and combination of parts, which will be hereinafter more fully described and particularly pointed out in the appended claims, reference` being had to the accompanying drawing, forming a part of this specification, and in which:

Figure 1 is a view partly in transverse vertical section and partly in side elevation showing a dispenser embodying the present invention;

Figure 2 is a similar view on a reduced scale showing the dispenser in use; and

Figure v3 is a fragmentary sectional view on an enlarged scale showing details of the construction of the connection between the discharge nipple and the fitting.

Referring to the drawing, the numeral I designates a tap rod in lthe form of a metal tube closed at its lower end as at 2 and, provided with openings 3 adjacent its closed lowerend.

To the upper portion of the tap rod a faucet 3 is provided and preferably embodies substantially the construction shown in my pending` application filed January 12, 1934, Serial No. 706,347.

Into the upper end of the tube I, a fitting 4 is secured. This fitting has an opening 5 extending longitudinally therethrough. The lower end of the opening 5 is connected with the upper end of a gas tube 6 which extends down through the tap 5 rod for a portion of its length and then extends laterally out through the wall of the tap rod as indicated atl. 'I'he upper end of the fitting 4 and the parts associated therewith provides a connection between the fitting and the discharge nip- 10 ple 8 of a holder or cartridge 9 for carbon dioxide gas. In the structure shown, the fitting 4 has a reduced extension I0 threaded into thelower end of a guard designated at II. The upper portion of this guard is enlarged as at I2 and telescopes 15 over the lower end of the cartridge 9 to provide a positive connection between the holder 9 and the fitting 4, which positive protective connection is independent of the nipple 8 and of the means associated therewith to provide a hermetic seal. 20 For instance, if the cartridge 9 is struck or pushed forcibly the strain will be taken by the guard I2 and the fitting 4, the nipple 8 being relieved of strain.

In the upper end of the longitudinal opening of the fitting 4 a sealing cup or bushing I5 is threaded and is provided with an annular flange I6, which flange with the cup I5 affords a seat for a sealing disc or washer I l of rubber. A valve trip I8 has one end secured in the opening of the bushing I5 and projects up through the opening in the disc Il. This lvalve trip pin has a restricted opening therethrough and the opening is even Afurther restricted at its upper end. The purpose of the pin I8 is to lift the valve I9 provided in the discharge nipple 20 away from its seat 2l and against the action of its spring 22 thereby allowing fluid under pressure to escape from the nipple 8.

From the foregoing, it will be obvious that when the nipple 8 is threaded down into the internally threaded portion 23 of the guard the lower end of the nipple will be brought against the top surface of the sealing disc I1 and pressing the same withinA the flange I6 and effecting sealing engagement between the sealing disc and flange and pin I8. When the nipple is screwed down sufliciently the pin I8 engages the lower end of the valve I9 and presses it upwardly and away from its seat so that pressure may flow past 50 the valve through the annular space 24 to the interstice between the engaged metal surfaces of the valve I9 and pin I8. These surfaces while engaged are not so constituted or machined as to prevent the pressure from flowing in between them and then in through the pin I8 down through the opening 5 of the iitting to the gas tube 6. sion 25 provided with an opening 26 communieating with the opening 5. At the outer end of the extension the opening 26 communicates with oppositely extending transverse openings 21 and 28.y rA gage 29 has its connecting member 30 threaded into the opening 21. A relief valve 3| is connected to the opening 21, the valve comprising a vented housing 32, a valve 33 normally engaged with the valve seat 34 under the influence of the action of a spring 35 exerted through a follower 36.

The .bushing I5 has a depending nipple 40 thereon which receives the open end 4I of a rubber check valve, the rubber check valve being clamped on the nipple by a ferrule 42 and having a longitudinal slit 43 therein designed to permit of passage of the gas under pressure outwardly therethrough but to prevent inward passage of pressure.

While I have shown and described one construction in which the invention may be embodied, it is to be understood that the construction shown has been selected merely for the purpose of illustration or example and that various changes in the size, shape and arrangement of the parts may be made without departing from the spirit of the invention or the scope of the subjoined claims.
