Johnston, R0. Box 41, Kalispell, Mont. Continuation of application Ser. No. 25,592, Apr. 29, 1960. This application Dec. 8, 1961, Ser. No. 159,818 12 Claims. (Cl. 137212) This invention relates to a novel and improved gas pressure siphon assembly for drawing fluids, such as beer, from containers such as beer kegs or barrels.
The primary object of the invention is the provision of a more efficient assembly of the kind indicated which involves means for preventing contaminating contacts between the beer or other liquid and the gas or air applied to the assembly under pressure for expelling liquid from a container.
Another object of the invention is the provision of an assembly of the character indicated above which involves a gas passage which is isolated and sealed from the beer passage, and novel automatic valve means, in conjunction with a tube defining a gas passage and having opening means opening into the container, which serves to vent gas or air from the gas passage into the container, only when the pressure of the gas or air entering the gas passage is greater than the gas or air pressure within the container, so that beer is forced out of the container.
A further object of the invention is the provision, in an assembly of the character indicated above, of a novel sectional tap nut for connecting the assembly to the tap hole plug of a container, and sealing means between one of the sections which is adapted to be compressed onto the plug by rotation of one of the sections relative to the other, this arrangement requiring only a partial turn of one of the sections to seal and secure the tap nut and the assembly to the plug.
Other important objects and advantageou features of the invention will be apparent, wherein, for purposes of illustration only, a specific form of the invention is set forth in detail.
In the drawings:
FIGURE 1 is a schematic view showing an assembly of the invention installed relative to a beer dispenser, a source of gas under pressure, and a beer keg, the last being broken away and in section.
FIGURE 2 is an enlarged horizontal section taken on the line 22 of FIGURE 1.
FIGURE 3 is an enlarged horizontal section taken on the line 3-3 of FIGURE 1.
FIGURE 4 is a further enlarged and contracted vertical transverse section taken on the line 4-4 of FIG- URE'Z.
FIGURE 5 is an enlarged horizontal section taken on the line 5-5 of FIGURE 4.
FIGURE 6 is a vertical transverse section taken on the line 66 of FIGURE 5.
FIGURE 7 is a horizontal section, similar to FIGURE 5, but showing the valve slits open and communicating with ports of the outer tube.
Referring in detail to the drawings, wherein like numerals designate like parts throughout the several views, there are shown a conventional beer keg 1h hav- 3,156,252 Patented Nov. 10, 1964 end, as indicated at 28, into a socket 36' in the lower side of a standard or conventional fitting 32, which is composed of an outlet cock 34, and a gas inlet cock 36 having a plug valve 37. The socket 349 communicates with the bore 33 of the outlet cock 34, which is blocked by an manual plug valve 40. At the meeting of the bore 38 and the socket 30 is a stop shoulder 42, which is spaced upwardly from the upper end of the outer tube 24. As shown in FIGURE 1, the outlet cock 34 is connected to a dispenser 44, as by means of a flexible tube 46; and the gas inlet cock 36 is connected, as by means of a flexible tube 48, to a gas cylinder 50 or other source of gas or air under pressure.
Positioned axially in and concentrically spaced within the outer tube 24 is a smaller diameter rigid inner tube 52 having an open bell 54 on its upper end which bears upwardly against the stop shoulder 42 in the outlet cock 34. The inner tube 52 has an open lower end 56 which extends below the lower end 58 of the outer tube 24. Near its lower end, the inner tube has secured thereon an annular seal 60, which acts to seal the space between the inner and outer tubes and serve as a closed lower end for the gas passage 62 which is defined between the two tubes. Threaded into the lower end of the outer tube 24 is a tubular ferrule 64 which spacedly surrounds the inner tube 52. Engaged in the lower end of the ferrule 64 is a strainer 66 which is connected to and is in communication only with the lower end of the inner tube 52.
The outer and inner tubes extend freely down through the opening 20 of the plug 16, and a tap nut, generally designated 68, surrounds the outer tube 24. The tap nut 63 comprises an upper section 70, which is journaled on the outer tube 24, has a lateral handle 72, and external screw threads 74 at its lower end; and a lower section 76. The lower section 76 is larger in diameter than the upper section 70 and has a tubular upper portion 73 which is threaded on the screw threads 7'4, and an enlarged downwardly flaring lower portion 8%? which has internal lugs 82 at its lower end, which engages under the flange 18 of the plug 16. A lower seal ring 84, of the diameter of the top 86 of the plug 16 is circumposed on the-outer tube 24 and bears upon the top of the plug. Circumposed on the outer tube 34 and compressed between the lower end 88 of the upper tap nut section 70 and the seal ring 84, is a plurality of smaller diameter seal rings 90. The lower tap nut section 76 has a lateral handle 92 thereon. To seal and secure the tap nut 68 on the plug 16 it is necessary only to turn the upper section 79 a partial turn, relative to the lower section 76.
On a level a short distance below the top wall 14 of the keg 10, the outer tube 24 is formed with circumferentially spaced ports 94, and at a location above the ports 94, the outer tube has a separation 96 which divides the outer tube 24 into upper and lower sections 98 and 1%, respectively. A tubular ferrule 102 has a larger ing an opening 12 in its top wall 14, in which is threaded a plug 16 having on its upper end a lateral annular g and a downwardly extending reduced diameter necklZii 1 diameter upper portion N4 which is suitably fixed in the upper section 98 at the lower end thereof,-and is externally threaded at its lower end, as indicated at 106, and the upper end or" the lower sectionis threaded thereon, to connect the sections 93 and 1%. The ferrule 152 has a reduced diameter lower portion 108 having vertically spaced annular ribs 11h extending therearound.
A flexible and resilient valve, generally designated 112, comprises an enlarged diameter, vertically elongatedintel-mediate portion 114 having a sidewall 116 in covering relation to the'ports 94 in the outertube 24, an upstanding reduced diameter neck 118 which is securably engaged on the lower portion 108 of the ferrule 102,
which is circumposed on the inner tube 52, and which terminates at its lower end in a cuff 122. The cufi" 122 has an upwardly and outwardly angled peripheral Wall 124 which has a peripheral edge 126 which bears sealingly against the interior of the outer tube 24. The sidewall 116 of the intermediate portion 114 of the valve 112 is formed with vertically elongated slits 128, which, as shown in FIGURES to 7, are registered with the outer tube ports 94. As shown in FIGURE 6, the bore 130 of the ferrule 102 is larger in diameter than and is concentrically spaced from the inner tube 52, so as to provide a restricted gas passage 132 between the valve 112 and the gas passage 62 outside of the inner tube 52, above the ferrule 102.
In operation, the outlet cock 34 and the gas inlet cock 36 being open, gas can flow under pressure from the tank 50, through the cock 36 into and down through the gas passage 62, through the restricted gas passage 132 into the valve 112. If the pressure within the keg is lower than that of the incoming gas, the sidewall 116 of the valve 112 is expanded against the interior of the outer tube 34, and its slits 128 open, as shown in FlG- URE 7, and enable flow of gas from the valve 112, through the slits 123 and the ports )4 into the keg 10, so as to force beer out of the keg, to the dispenser 44, via the screen 66 and the inner tube 52, and not otherwise. When the pressure in the keg 10 balances the pressure of the incoming gas, the valve slits 128 close and the outer tube ports 94 are sealed by the valve sidewall 116, so that there is no static contact between the gas and beer in the gas passage 62, with the result that beer reaching the dispenser 44 through the siphon 22 is in a cleaner and fresher condition.
This application is a continuation of my copending application Serial No. 25,592, filed April 29, 1960, now abandoned, for Beer Siphon Assembly.
