(c1. isz- 143i This invention relates to dispensing apparatus and is designed more especially for dispensing beer in small quantities or Vby the drink.
It is contemplated, according to my invention,
*' that beer shall be delivered by the brewers in large glass jars Vor bottles and/these bottles or jars shall be setupon an ice box through which thel beer is drawn when'it is to be served. It is a particular object of the invention to provide lomeans whereby the jar or container will be sealed when delivered but access to the contents will be provided automatically when the jaris inverted and set in operative position upon the Other objects oiV the invention will ice box. appear as the description proceeds and the invention resides in certain novel `features which will be particularly defined in the appended- Figure is an enlarged detail section through the air delivery nozzle.
Figure 4 isa detail section through themouth of the' jar asthe same appears before being set -Figi1re` 5 is a` section showing a/modi-cration.f
VIn the dravving,H the reference numeral I indicatesan vicev b'ox which maybe ofany desired formation and oi'anysuitablematerial In the i topbofkthe ice box is a hinged door 2 to facilitateplacing-of` ice within the box, and at one end at the bottom thereof is a drain cock 3 to drain Water from the box when the latter is to` be cleaned. An overiiow Ypipe 4 is alsoI fitted in one wall of the box so that the cooling water in the box may be maintained at a desired level. Upon the top of the ice box is a rack or circular frame 5 which may be constructed of light rods or stout wire and is adapted to receive and support a large jar or bottle 6 which is preferably formedV of glass in order that the contents of the jar may be noted at any time. In the wall of the jar is formed a conduit or air passage 1;
which extends from the mouth of the jar to a point near the bottom of the same and at said point opens into the jar, as clearly shown in Figure l'. At the mouth of the jar a bung or cork 8 is tightly tted Vand said bung or cork is formed with a central passage or opening S Vwhich is adapted to receive a nozzle Il) on the end of an air pipe when the jar is iitted upon theiceV box. When the jar is delivered by the brewer, a plug ll is fitted closely in the opening 9 oi the cork orY bung 8 so that the end of the air'passage is sealed and the beverage cannot escape from the jar through said passage. In a similar manner, the mouth of the jar has a bung or stopper IZ fitted tightly therein and said stopper or bung l2 has a central opening I3 in which is tighnyaed apmg m so that, when it# the jar -is filled and delivered by the brewer, the contents of the jar will be effectually sealed against contamination. A coil l5 is disposed in the bottom of the ice box and has one end secured in a Wall of the box at the bottom of ltr:
the same and equipped with a faucetl E6 through which the contents of the jar may be drawn as desired. The inner end of the coil l5 is carried upwardlyawithin the tank, as shown at I1, and
is connected by a collar or union i8 with a nozzlelS which is adapted to enter the opening i3 in the stopper'or bung I2 when the bottle is inverted andY brought down over the end of the nozzle.` As shown clearly in Figure 2, the nozzle is formed with an external ange 20 resting upon` the top of the ice box and a gasketv or washer 2| is disposed vover said flange Vso that leakage of the beverage around the nozzle will be resisted. The nozzle is permanently secured within the ice box by solder or welding, as indi- 36 cated at 22. The nozzle lli is adapted to enter the opening 9 in the bung or cork 8 and is, like the nozzle i9, formed Vwith a flange 23 which bears upon the top of the ice box and supports a gasket 2li upon which'the end or mouth of thejar bears, as shown inFigure 2. The nozzle lli is secured in the top of the tank by a coupling sleeve or collar 25 which is threaded onto the lower end of the nozzle, as clearly shown in FigureV 3, and has its lower end threaded onto 40 Va nipple 26 which receives the end of a hose or flexible pipe 2l, said pipe 21 extending through a side or end of the ice box to a source of air under pressure. Seated upon the nipple 26 is a check valve 28 in the form o'f a disc adapted 45 toA cover the bore of the nipple, as shown in Figure 3, and held to its seat by a retractile spring 29 which is anchored in the nipple at Vone end and has its opposite end attached to the valve, as shown and as will be understood. 50 This check valve will permit the iiow of air to and into the jar but will prevent reverse flow so that the proper aeration and pressure upon the beverage will be maintained.
From what has been said, it will be understood 55 that, when the jar is to be put into dispensing position, it is inverted so that the openings in the respective bungs or Stoppers will be alined with the respective nozzles I and I9 and then the weight of the jar will cooperate with a slight pressure exerted thereon to force the same down over the nozzles, the nozzles bearing against the respective blocks` II and I4 which will be thereby forced from the respective openings and Will float through the beverage and through the air passage I to positions immediately under the inverted bottom of the jar. The beverage will then flow by gravity from the jar to and through the coil I from which it may be drawn as desired through the faucet I6. It will be noted that the coil and the lower portion of the pipe I 1 are embedded in the ice and ice water so that the refrigerant will be applied directly to every portion of the surface possibly, the small undersurface which may be in contact with the bottom of the tank, but it is also to be noted that when the parts are originally assembled the coil will be out of contact with the bottom of the tank so that its entire surface will be subjected to the refrigerating action of the ice Water.
In Figure 5 is shown a modification in which the nozzle 30 is coupled to the end of the dispensing pipe 3| just as the nozzle I9 is so coupled, but the nozzle 30 is formed with an auxiliary passage or bore 32 extending from a nipple 33 on the side of the nozzle and the air pipe 34 is coupled to said nipple. With this arrangement, the bung 8 and plug II are dispensed with and the single nozzle will eject the plug I4 when the bottle or jar is forced down over the nozzle and the air will then enter directly into and rise through the beverage so as to aerate the same. In the rst described form of the invention, the air, of course, is admitted to the jar above the beverage and will exert pressure thereon,
" avoiding accidental while in the form shown in Figure 5, the air rises through the beverage to reach the upper end of the jar and there accumulates to exert the desired pressure upon the beverage.
In both forms of the invention the construction'is simple and the jar may be easily set in place and when set in place will Ybe automatically so disposed that communication between the jar and the dispensing faucet is established. As shown in Figure l, the jar is provided with a spiral or inclined lug or bead 35 which will facilitate the application of an outer cap covering both the bungs and thereby further protecting the contents against contamination and also release of the sealing plugs.
