Description:

This invention relates to improvements in beer dispensing equipment, and refers particularly to direct draw dispensers in which the beverage is cooled while in its keg or container, and the dispensing faucet is connected with the keg by a relatively short conduit.

Dispensers of this character are now generally built in the form of cabinets adapted to be refrigerated either mechanically or by the use of ice, and have faucets mounted in any suitable 1 manner, preferably on the upper portion thereof, which faucets are connected through conduits with the kegs contained in the cabinet.

Heretofore, no adequate provision was made for keeping the beverage cold throughout the en- 1 tire extent of its passage to the faucet, and as some part of the beverage is at all times in the faucet and the adjacent portion of the conduit connecting it with the keg, it is desirable that means be provided for maintaining the conduit 2 cold throughought its entire extent.

It is therefore an important object of this invention to provide a practical manner of supporting or mounting the faucet so that the conduit leading thereto is kept at the same temperature 2throughout its entire length.

Another object of this invention is to provide a dispensing head or faucet support which is so designed as to project above the top of the dispensing cabinet or bar, not only to enhance the c appearance of the dispensing unit but also to facilitate the disposition of glasses under the faucet.

Another object of this invention is to provide a dispensing head which is exposed to view above the top o t of the cabinet or bar and which has means for keeping the conduit cool throughout its entire length, and, in addition, is so desigred as to permit ready access to the conduit for cleaning purposes. ,A further object of this invention is to provide a dispensing head of the character described which mounts on top of a bar or dispensing cabinet and has its hollow interior directly communicated with the interior of the cabinet so that the conduit which rises upwardly therethrough for connection with the faucet is kept at the same temperature throughout its entire length.

A further object of this invention is to pro- s0 vide a dispensing head of the character described which is mounted on and forms a unit with the tap rod which is insertable down through a hole in the top wall of the cabinet aud into a keg positioned therebeneath. 5 With the above and other objects in view which will appear as the description proceeds, this invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described, and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein-disclosed invention may be made as come within the scope of the claims.

.0 The accompanying drawing illustrates two complete examples of the physical embodiment of the invention constructed in accordance with the best modes so far devised for the practical application of the principles thereof, and in 5 which: Figure 1 is a view showing the back of a dispensing cabinet equipped with the dispensing unit of this invention; Figure 2 is an enlarged longitudinal sectional 0 view through the dispensing head; and Figure 3 is a view similar to Figure 2, illustrating a modified form of dispensing head.

Referring now particularly to the accompanying drawing in which like numerals indicate like 5 parts, the numeral 5 designates a cabinet of the type generally employed in direct draw dispensing of beer, and which, as is customary, is adapted to be refrigerated either mechanically or by the use of ice, and into which one or more kegs 6 may be set.

The top wall 7 of the cabinet, which may constitute the surface of a bar, has a hole 8 therethrough through which a tap rod 9 projects. The lower end of the tap rod, as is customary, enters the keg 6 through a tap 10, the tap being provided with the customary check valve (not shown) to permit the introduction of gas under pressure from any suitable source through a hose I .

Mounted on the upper end portion of the tap rod and forming a unit therewith is a dispensing head, indicated generally by the numeral 12.

This head forms a support or standard for a faucet 13 and is of hollow or tubular construction to enable cold air from the inside of the cabinet to come in contact with the upper end of the tap rod.

Specifically, the head 12 consists of a tube 14 of a size to fit into the hole 8 and form substantially a continuation thereof, and an outer cylindrical shell 15 encircling the tube in spaced relation thereto. The lower end of the outer shell is closed by a plug 16 which serves as a spacer between the tube and the shell, and the upper end of the shell extends above the top o the tube, as shown.

The tube 14 is joined to the tap rod 9 by spiderlike spacer arms 11 and 18, the former being located at the lower end of the tube 14 and the latter at the upper end thereof.

The spacers 18 connect with and may be a part of an elbow 19 which provides a connection between the faucet 13 and the upper end of the tap rod 9. This elbow has a tapped opening 20 in line with the tap rod, which is normally closed by a plug 21, and which, upon removal allows the insertion of cleaning instrumentalities into the tap rod.

The space between the tube 14 and the outer shell is filled with a suitable insulating material 22, such as "rock wool," which insulating material also preferably surrounds the elbow 19. In this manner, objectionable heat transfer from the cold interior of the tube 14 is reduced to a minimum, and, as will be readily apparent, the inside of the tube being communicated with the cabinet interior, has substantially the same temperature as prevails in the cabinet. Consequently, substantially the entire path of the beverage is kept at the desired cold temperature.

Access is afforded to the plug 21 by removing a cover 23 which closes the open top of the outer shell, and which preferably includes a pad of insulating material 24.

While the introduction of the lower end of the tube 14 into the hole 8 may be relied upon to properly center the dispensing head, it is desirable to provide a flange 25 which is fixed to the top wall 1 of the cabinet and which receives the lower end of the shell 15. Friction means 26 provides a snug grip between the flange 25 and the shell 15.

In the modified embodiment of the invention illustrated in Figure 3, the dispensing head is permanently mounted on the top wall 7 of the cabinet, for in this construction, the conduit 21 which connects the faucet 13 with the keg is flexible so that the tapping of the keg may be done before the keg is placed in the cabinet.

However, as in the embodiment already de. scribed, the dispensing head comprises the samo tube 14 which extends down into the hole in th< top wall of the cabinet and the outer shell II encircling the tube in spaced relation thereto The lower end of the shell 15 is secured to thi top of the cabinet by a flange 28, and its opel upper end is closed by a removable cover 23 sim ilar to that employed in the other construction The specific manner in which the connectioi is established between the faucet and the flexibl conduit 21 is different from that employed in th embodiment shown in Figure 2, and comprises coupling 29 adapted to be threaded onto a nippl 30 fixed to the faucet.

From the foregoing description taken in con nection with the accompanying drawing, it wi be readily apparent that this invention provide a substantial improvement in beer dispensin equipment by maintaining the entire condu leading from the keg to the faucet at the desire cool temperature, by enhancing the appearanc of the dispensing head, and facilitating u thereof.
