lApplication November 15, 1940, Serial No. A 365,831

2 Claims. (Cl. 284-49) This invention relates to dispensers and, more particularly, to an improved dispenser for use in conjunction with beer barrels and other liquid containers.

One object of the invention is to provide a dispenser which may be quickly attached to a beer barrel or the like and which will, when attached, insure ready insertion of a draft pipe in the barrel for permitting drawing of the contents thereof and without interfering lwith supply pipes or the like.

Another object of the invention is to provide a dispenser which may be readily attached to beer or other fluid containing barrels Without the need of Wrenches or other tools, the use of which would interfere with the tapping of the barrel.

A further objectof the invention is rto provide a dispenser employing a one piece body having a valve therein which will be operative for sealing the barrel or keg upon withdrawal of the draft tube without loss of pressure from the keg .or

barrel.

Another object of the invention is to .provide a dispenser having a one piece body which forms a housing for `both the sealing valve and the gas inlet valve employed.

A further object of the invention is to provide a device of this character employing an improved automatic inlet valve for gas orother fluid under pressure. v

A still further object of the invention is to provide a vdispenser lwherein the liuid pressure valve employed eliminates the need for closing valves on the gas pressure line when the gas pressure is relieved from the barrel.

And a still further object of the invention is to provide a dispenser of this character Which is simple in constructionand which will be highly elicient in use.

Other objects of the invention, not specically mentioned hereinbefore, will become apparent during the course of the following description.

In the drawing forming apart of my application,

Figure 1 is a vertic-al sectional View showing my improved dispenser as'it would appear in operative position on a barrel or keg, with a draft tube in position extending therethrough and into the barrel.

Figure 2 is a vertical detail sectional view on the line 5-5 of Figure 1.

' Figure 3 is a vertical detail sectional View on the line 6--6 of Figure 1.

lFigure -4 `is ardetail :side elevation, partly .dn

section, showing the detachable elements of the gas pressure valve, and

Figure 5 is a detail sectional View, partly in elevation, of the gas pressure valve.

Referring ,now more particularly to the drawing, wherein like numerals of reference designate like parts throughout the several views, the numeral I indicates in general the lbody of my irnproved dispenser. The body is formed with an exteriorly threaded depending tubular shank 2 on which is screwed -a connecting sleeve 3, said connecting sleeve having a bayonet connection 4 for engagement with a lmating bayonet connection 5 on the `top wall `6 `of `a barrel or keg. Carried within the connecting sleeve 3 is a com- .pression ring 8, anddisposcd beneath thecompression ring is a packing ring 9. As best `seen in Figure l, when the device is .installed on a barrel, Vthe connecting sleeve is screwed down upon the shank a suicient distance past the end of said shank so that the mating bayonet elements 4 and 5 may be `properly engaged. The sleeve 3 is, however, moved such a distance that, when the connecting `sleeve is rotated to lock the bayonet connection, the compression ring 8 will compress the sealing gasket or packing ring 9 and 4thus insure a -tight seal between the body I and the head 6 of the barrel or keg.

The body I is Aformed with an integral upwardly enlarged valve chamber I0, .said valve chamber having a iiange II at its upper rim and 'being formed with an ,integral gas linlet pipe I2', said gas inlet pipe having Yan enlarged free end portion .defining a combined coupling and gas pressure valve element I3, said gas pressure valve construction to be described in more detail hereinafter.

Normally closing the ktop of the valve chamber I0 is a cover I4, said cover v,having a wall I5 ,and an integral gland I6. The `wall I5 is .secured to the `'lange II of the valve chamber rIIII by means of screws Il, ,a suitable kgasket I8 being disposed between the wall I5 and the upper `surface ,of the rim II to prevent leakage. The Wall ,I5 is provided with an axial opening ,I9 which cornmunicates between theinterior of' the gland ,I6 and Vthe interiorof the `,valve chamber Ill, said opening `being in vertical alinement `with the ltubularshank `2, which shank .is .in communication with the interior ofthe valve chamber I0 .and the interior ofthe barrelor keg LI. 4Mounted within the gland I6 Aand extending about vthe opening .I v9 thereabove isa packing Washer 20. .As will beseen in Figure 1 ,'the .gland 'I6 is interiorly threaded and receives thethreaded shank 2l of a sealing nut 22, the nut having a relatively large manually engageable portion 23. Attention is particularly called to the fact that the lower edge of the opening I9 defines a valve seat, which, for convenience, has been indicated at 24.

The wall I has mounted on its lower surface a yoke 25. The yoke 25 hingedly mounts a valve member 2S, said valve member having an attaching shank 2'I, which extends between the arms of the yoke 25 and is swingingly connected therewith by means of a pin 23. The valve member 26 includes a circular supporting face 23 on which is mounted a valve element 30 which is formed of rubber, liber, or other suitable material. The valve element 3o is secured to the face 29 by a screw having a round head 3|, the purpose of which will be set forth presently. The valve member 26 is normally urged toward the valve seat 24 by means of a spring 32 which has a bow 33 engageable with the rear of the supporting face 29 and free end portions which are engaged with the wall of the valve chamber I9, the spring having central portions coiled about the pin 29, as shown at 34.

The construction of the gas or fluid pressure valve will now be set forth in more detail. The gas pressure valve includes the coupling element I3 and a detachable valve element 35, said valve element including an inlet nozzle 33 which is reduced and ribbed to receive conveniently the end or" a rubber uid supply tube 3l.

The valve element 35 is formed with a recess 33 which communicates With the opening 39 of the nozzle 35. The element 35 is formed with an integral cage 40 which is formed on the end face 4I of said element, said end face 4I being flat and carrying a gasket 42. As will be seen, the gasket 42 lies against the flat face 4I of the element 35 in surrounding relation to the cage 40. The cage 40 defines a valve chamber 43 which communicates With the recess 33. rIhe cage 49, further, is formed with a threaded mouth 44 into which is screwed a guide sleeve 45, said guide sleeve having an inner rim defining a valve seat 46.

Mounted within the valve chamber 43 is a spring pressed valve 4l, which, as best seen in Figure 5, is normally engageable with the valve seat 46. The valve 41 is formed with an axially disposed stem 48 which extends into the recess 38 and provides a guide for one end of an expansionspring 49, the other end of said spring being engageable against the inner wall of the recess, said spring urging the valve 4l toward the valve seat 46.

The coupling I3 is interiorly threaded at its base., as shown at 59, and screwed into the threaded base is a valve opening element 5I, said valve opening element having an actuating sleeve 52 and a nipple 53, said nipple extending into the pipe I2 which, as best seen in Figure 1, is formed with a slightly enlarged bore 54. Carried on the nipple 53 within the Ybore 54 is a rubber check valve 55. As clearly seen in Figures 3 and 4 of the drawing, the coupling I3 and the valve element 35 are formed withl mating bayonet elements 5S and 5'I, the elements 56 being mounted on the inner rim of the coupling I3 and the elements 5'I being mounted on the free end of the cage 4D. As will be seen, the elements 5l are formed With inclined Walls 58 which ride on the inner walls 0f the elements 56. It will also be noted that the elements 56 are diametrically disposedon the coupling I3 and the elements 51 are likewise disposed on the valve element 35.

In order to permit easy manipulation of the valve element 35, I provide a handle 59 which is formed integrally on said valve element.

The operation of my improved dispenser Will now be described. As previously stated, my improved dispenser is attached to the wall 6 of a barrel by engagement of the mating bayonet elements 4 and 5, the connecting sleeve 3 being screwed on the shank to such a position that the ring 8 will compress the sealing ring 9 when the bayonet elements are turned home. The valve member 25a of the dispenser will, when the dispenser is in inoperative position, be in engagement with the valve seat 24 for sealing the keg or barrel and preventing escape of air or gas therefrom. In this connection, it is desired to state that the check valve 55 will also operate to prevent escape of gas from the dispenser and keg.

When it is desired to draw from the contents of the barrel, it is only necessary to insert a draft tube, shown at 69, through the sealing nut 22 and the body I into the barrel. The draft tube when being moved to operative position, will function to drive the bung in the bunghole 6I into the barrel. After the draft tube has been moved to the keg or barrel the nut 22 is turned for engaging the sealing gasket 20 tightly about said draft tube for preventing leakage. It is desired particularly to call attention to the fact that, as the draft tube moves downwardly, the end thereof engages the round head screw 3| of the valve member 25a and swings said valve member downwardly and laterally Within the chamber I9 to the position shown in Figure 1. The provision'of the round head screw 3l prevents any damage to the valve element 33 by the end of the draft tubewhen said valve is being unseated.

It is asumed for purposes of illustration that there is a sufficient amount of pressure within the barrel or keg to force the beer or other liquid upwardly through the draft tube. If this condition prevails, the valve element .will be out of engagement with the coupling I3. As stated, the check Valve 55, together with the gaskets 9 and 2U, Will effectively prevent escape of pressure from the barrel or keg. Let it now be assumed that the pressure within the beg or barrel I is not sufficient to force the liquid through the draft tube. In order to supply additional pressure, it is only necessary to attach the valve element 35 to the coupling I3 This is done by manipulating the handle 5S for interengaging the bayonet connecting elements 56 and 5l. As the bayonet connecting elements are being turned home, the actuating 'sleeve 52 will pass through the guide sleeve 45 and into engagement with the valve 4l, thus unseating the valve and permitting flow of gas or other iiuid from the tubeY 3,7, which is, of course, connected to asupply of vfluid under pressure, through the bore 39, the recess 38the chamber 43, the element 5I and the check valve 55 into the pipe I2 and, thence, into the cham*- ber I9 downwardly about the tube G0 into-'the barrel. When a sufficient amount of gas under pressure has been placed in the barrel, it is only necessary to grasp thev handle 59 and partially rotate the valve element 35 for permitting unlocking of the bayonet elements 56 and 5l. Whenthis is done, the valve element 35 is removed from the, coupling I3, which acti-on will cause displacement of the actuating sleeve 52 from the'guide sleeve 45A. The compression spring. `49'wi11 then urge the valve 4l into engagement with thevalve seat 46 for stopping the 110W of gas under pressure from the pipe 31.

During the operation of placing of gas under pressure in the barrel or beg, the gasket 42 will effectively prevent escape of fluid from between the coupling I3 and the valve element 35.

When it is desired to remove the tube 60, the nut 22 is loosened for loosening the packing 20. The tube is then withdrawn from the body. As the lower end of the pipe passes upwardly through the valve chamber I0, the valve member 25a will be urged by the springupwardly into engagement with the valve seat 24. It is to be noted that the packing gasket 20 is disposed above the valve seat so that said valve member will be permitted to become fully seated before the lower end of the tube 69 has cleared the said gasket 20. It will thus be seen that there will be no loss of pressure incident to the removal of the draft tube from the dispenser.

Having thus described the invention, what is claimed as new is:

1. A valve controlled pipe coupling comprising a relatively stationary coupling member having one end thereof enlarged to form a chamber open at its outer end and a reduced neck at its inner end, a valve opening element including an actuating sleeve projecting within the chamber, a check valve disposed within the neck and engaging the adjacent end of the actuating sleeve, a movable coupling member detachably engaging the stationary coupling member and provided with a tubular cage, a guide sleeve fitting within the cage around the actuating sleeve and provided with a valve seat, a main valve carried by the movable coupling member and engaging said seat, a gasket interposed between the stationary and movable coupling members, and a nger piece carried by the movable coupling member for rotating the same to compress the gasket and force the actuating sleeve against the main valve to unseat said main valve when said members are coupled, and means for holding the coupling members in assembled position.
