Claims. (o1. 225 -2) This, invention relates to attachments. for kegs, barrels or other containers whereby the contents may be tapped. off or refrigerated or both..- i

The main object. of the. invention. is to provide improved. means-whereby a key,'barrel or other container. may be. readily and'efijicien'tly tapped.

Aiurther object of the invention is to pro.- vide improved. means. whereby the contents of a keg, barrel or other container may bereadily and efficiently refrigerated l A further object of the invention is to pro videimproved meanswhereby .a barrel or other container may be readily and efficiently tapped and its contents refrigerated. I

A further object of the invention'iisgto provide means for efliciently and readily tapping a keg, barrel or other container whereby the container is maintainedclosed against contamination from the exterior at all times. t

A further object of the invention is to" provide an attachment for kegs, barrels or other containers whereby the container may be readily.

and efliciently tappedQthe interior of the container being normally shut oif'fr'om the exterior and automatically opened by the attachment'of the tapping device.

A further object of the inventi'on'is to provide an attachment for tapping a kegQba'rreI or other container, which is readily appliedand efiiciently operates and which provides a means for tapping ofi the contents and also for supplying pres sure to force'the contents from the container.

Other and ancillary objects of'theihvention will appear her'einafter. Y v

In the accompanying drawing which illustrates the invention 1 is a sideelevationofi apparatus according to the invention, such apparatus being, how

ever,'partly in section and the keg to which it is applied being shown invertieal-axial section; I Fig. 2 is an axial section, on an enlarged scale, through the bushing and tapping and refrigerating attachmenhcertainof the adjacent parts being omitted;

Fig. 6 is a section of the bushing on the line In the accompanying draWingwh-ich illustrates the invention, in -the headof thekegl isscrewed a bushing 2 ,having', the. inclinedbayonet slots ,3 in'oppostie sides, such. bayonet slots communi-, cating with the upper edge of the bushing by means of axially extending. slots 8, and having holes 4 inthe diaphragm. constituting its bottom throughwhich the eduction .or cooling pipes may be-extendedintothe keg aswillbe hereinafter referred to..- v U 1 In the bottom-of the bushing 2. is also a central hole. 5 within which isrotatably mounted thespindle. 6 to which is secured the valve .1 adapted to be. movedinto and. out of position toclose. the holes! by turning the spindle 6. The detachable tapping and cooling attachment .to be applied to. the keg. bushing comprises. a body portion 9' havingvthe turning Wings 3 4,- and provided. at.

diametrically opposite points with lugs I 0 adapt ed: tobe entered=within-the slots. 8 and then turned into the slots/3,. the inclination of which will. draw the body tightly against the" upper part of. the bushing,. a gasketl I of rubber, or other suitable material,..being compressed, between ,the

body and. the. bushing. to make a tight joint.

Within the. body ,s all two, bores, I2 and l3 within which longitudinally slidethe tubes I4 and I5. Both'of these tubes and their -manner of operation may be precisely alike,..when, they may both be eduotion tubes for thecontents of.

the keg or. barrel, as for instance they may lead,

from theinterior of a keg to.a,. plurality of faucets.. In the structure shown, however, one of the tubes, namely I5, is used for cooling or refrigerating purposes as will, later appear. The tubes l4 and I5 are respectively surrounded by gaskets I 6 and I1 which are compressed'bythe gland nuts I B and I9 having turning wings 20' and 21 at their upper exposed sections. c

When the gaskets l6 and llarecompressed' they will bear tightly against the pipes 14 and 66 of Fig. 5, the other parts being omitted; and

Fig. 7 is a fragmentary view showing a portion of the' attachment in side elevation and a I5 so that a fluid-tight joint is formed but longitudinal sliding of the tubes and. l5iis permuted;

Threisaclearance in the bore l2 about the pipe I4 such clearance communicating through a passage 22 with a source of'co'mpressedainsuoh passage beingcontroll'ed' by thecock 23. The air v 1 under pressureii's admitted to the. urface of the liquid in the keg; to afford. pressure to eject the liduid,'from the bore l2'to the interior of the bushing 2 and thence through the" holes 4 (when uncovered by the valve 1) intothe interioro'f the keg above'theliquid.

The: pipe' [4" is adapted to be attached at. its

fluid, which pipe communicates through the controlling cook 29 with any suitable source of cooling or refrigerating fluid. The pipe 28 extends to a point adjacent the lower end of the pipe so that the cooling fluid passing downwardly through the pipe 28 will issue from'the end thereof and then pass upwardly within the pipe I5 and about the pipe 28 to anexit pipe 30' at the upper end of the pipe l5.

The lower end of the pipe 28 is closed in fluidtight fashion by means of a tip 3| screwed therein, such tip being similar tothe tip 25 but having no openings therein to communicate outside the pipe IS, the

tips

25 and 3| being of substantially the same exterior configuration.

The body 9 is provided with a socket 32 of square cross section whichis adaptedupon the inception of the attachment of the body to the bushing, to permit the end 33 of the valve spindle. which end is of square cross section, to. enter within it. The turning of the body 9 to' secure it in the bushing will then turn the valve so as to uncover the openings 4. Conversely the turning of the body 9 to detach it will cause the valve 1 to closethe holes 4 in a fluid-tight manner.

The

tips

25 and 3| are of such diameter that they will pass through the holes 4 but will not pass through the bores l2 and I3. This permits the pipes l4 and I5 to beslid longitudinally out- I wardly until the

tips

25 and 3| are in the bushing (see Fig. 2) when they will not interfere with the movement of the valve 1 to close the openings 4 and at the same time withdrawal of the pipes l4 and I5 from the body 9 cannot be effected without unscrewing and removing the

tips

25 and 3|. This prevents the disassembly of the pipes and body accidentally or without afixedpurposeto doso. g f j In operation theplpes l4 and |5'will be 'slid inwardly until their inner ends are adjacent the this position it will be seen that the cooling fluid traverses the liquid in the keg substantially from top to bottom and that the air pressure on the top of the liquid forces it into' the lower end, of the pipe 4 whence it is transmitted to the tap or serving faucet.

Ordinarily the tapping and cooling attachment.

were applied, the lugs l0 would be entered within the slots 8 and the spindle end 33 in the socket 32. Turning of the body portion 9 to tighten it in the bushing by means of the inclined bayonet slots 3 would turn the valve 1 so as to uncover the openings 4. Air pressure would thus beadmitted through the openings4 to the top surface ofthe liquid in the container. The pipes l4 and I5 would then be pushed inwardly until their lower ends were adjacent the bottom of the keg (see Fig. 1), the cooling fluid entering through the tube 28 and passing upwardly in the tube l5 substantially from the bottom to the top of the liquid in the keg whereby an efficient cooling or refrigeration is efiected. Further the air pressure on the surface of the liquid forces the liquid in through the tip and up through the tube |4 under any desired eduction pressure (depending upon the air pressure applied), controlled by the service tap.

, When it is desired to remove the attachment the tubes l4 and |5 are slid longitudinally outwardly until their

tips

25 and 3| are within the bushing 2. The turning of the body 9 todetach it from the bushing 2, will then turn the valve spindle so that the valve 1 will close the openings 4. The keg, therefore,.when emptied, will always be automatically tightly closed against the ex- I terior so that no dirt, insectsor other foreign 4 bottom or lower head of the keg (seeFig. 1). In

objects can enter the keg while it is empty and thus deleterious fouling of the interior of the keg is prevented, the keg always being closed to the exterior except when'it is opened for cleaning and filling at the brewery or when it is in operation of having its contents removed at thedispensing point.

While the invention has been illustrated in what is considered its best application it may have other embodiments without departing from its spirit and is not thereforelimited to the structure shown in the drawing.
