6 Claims.

This invention relates to improvements in beverage dispensers, and refers particularly to direct draw beer dispensers.

Beer dispensers of this type consist of a suitably refrigerated cabinet in which one or more kegs of beer are placed to be dispensed from faucets mounted at the top of the cabinet and connected with the kegs by relatively short ducts or beer lines. The cabinet top is generally at bar height and serves as a bar or counter over which the beer is served.

To take full advantage of the sales psychology which attends the direct draw method of beer dispensing, the beer should be drawn in plain view of the customer. This requires the dispensing faucets to project up from the top of the cabinet sufiiciently to enable a glass to be set thereunder. The faucet standards are, therefore, quite tall. x

As a consequence, a substantial length of the duct or beer line which connects each faucet with its respective keg extends outside the cabinet proper; and although the faucet standard is insulated, the warm room temperature soon warms the upper end of the beer line. The first beer drawn after a relatively short period of non-use is thus not at the proper temperature and foam content for optimum palatability. I

Many attempts have been made in the past to overcome this disadvantage, but heretofore, nothing practical has been devised.

It is, therefore, the primary purpose of this invention to provide a direct beer dispenser so designed and constructed that the entire duct leading from the keg to the faucet will be kept cold or at the same temperature prevailing inside the cabinet. I

More particularly, it is an object of this invention to provide a direct draw beer dispenser wherein the faucets are mounted on hollow insulated standards which enclose the beer line and wherein means are provided for positively circulating cold air from the interior of the cabinet through the hollow faucet standards.

Another object of this invention is to provide means for effecting the desired positive circulation of cold air through the hollow faucet standards which is so constructed that it does not necessitate re-design of the present direct draw dispensers.

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 hereindisclosed invention may be made as come within the scope of the claims:

The accompanying drawings illustrate 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 which:

Figure 1 is a view in elevation showing the back of a direct draw beer dispenser with parts broken away and in section;

Figure 2 is an enlarged vertical sectional view through the upper portion of the dispenser unit;

Figure 3 is a horizontal sectional view taken through Figure 2 on the plane of the line 3-3; and

Figure 4 is a view similar to Figure 2 illustrating a slightly modified embodiment of the invention.

Referring now particularly to the accompanying drawings, in'which like numerals indicate like parts, the numeral 5 designates the cabinet or box of a direct draw beer dispenser which in the embodiment illustrated in Figure 1 is of a size to hold two kegs 6. The kegs are inserted and removed through doorways in the back of the cabinet, closed by doors 1.

The top of the cabinet 8 provides a counterlike service top or bar across which the beer may be served. Along the rear, the cabinet top is preferably stepped, as at 9, with the top of the step constructed as a drain board.

At a point substantially above each keg location, the cabinet top has a hole l0 therethrough and extending up from the top directly over each hole is a hollow insulated faucet standard ii.

Mounted on each faucet standard near the upper end thereof is a dispensing faucet l2. A duct or beer line i3 connected to each faucet inside its hollow standard provides a detachable connection with its respective keg. The connection of the duct to the keg involves the customary tap Hi. Pressure is applied to the keg from any suitable source through a pressure line I5 which connects with the tap in the usual manner.

The interior of the cabinet is refrigerated by means of a mechanical refrigerating unit including a heat exchanger I 6 through the coils of which a suitable refrigerant is circulated by a compressor (not shown). The compressor may be remotely located but generally it is housed within a small cabinet IT in juxtaposition to one end of the main cabinet. The manner in which the coils of the heat exchanger are connected with the compressor forms no part of this invention. and therefore. has not been shown.

The heat exchanger I! is located in the upper portion of the cabinet-and is disposed edgewise and at an angle across the space directly beneath the top wall I and between the front wall ltandtheriserliofthestepi.

A fan or blower 2| supported in any suitable manner within the cabinet induces a circulation of air through the heat exchanger and around the interior of the cabinet.

Heretofore, attempts were made, as shown in the copending application of Hilbert R. Pei-lick, Serial ljIo. 257,430, to have the interior of the faucet standard at the same temperature of the cabinet interior but all expedients previously proposed have fallen short desideratum. V

The present invention, however, insures the maintenance of the same temperature within the hollow faucet standard as prevails within the cabinet. from the cabinet interior through the hollow faucet standards by dividing each standard into two passages 2| and 22 connected at the top where the ducts l3 connect with the faucets, and directing cold' air from the cabinet up; one passage and down the other.

It is to be observed that the heat exchanger extends crosswise between thefaucet standard of accomplishing this To this end, air is forced to circulate locations so that one standard is in front of the heat exchanger and the other behind the heat exchanger, and that the fan or blower is likewise positioned between the two standards.

In the faucet standard which is located in front of the fan and heat exchanger, the passage forming means comprises an air duct 23 which extends up through the adjacent hole It and into the hollow faucet standard with the lower end portion thereof projecting a substantial distance beneath the top wall 8. The lower end of this duct connects with the small end of a suction mouth or chamber 24, the large open end of which terminates adjacent to the back of the fan.

Hence, the fan or blower draws the air down through the duct 23 and out through the chamber 24, thereby causing cold air from the cabinet interior to flow into the faucet standard to the extreme top thereof.

The means by which the other faucet standard is divided into the two passages 2| and 22 consists of a longitudinal partition wall 25 extending up through the adjacent hole ill and into the hollow standard to a point near the top thereof. The lower end of this partition projects beneath the top wall 8 and forms the closed end of a scoop 26 mounted to collect some of the air issuthe top wall to form a trough or duct open at the bottom and that the heat exchanger extends diagonally across this trough or duct. Hence, the air currents are guided and directed to pass through the heat exchanger without in anywise complicating the design or construction of the dispenser.

gamma In the modified embodiment of the invention illustrated in Figure 4, the cabinet is large enough to hold three kegs: and the heat exchanger is divided into two sections ill and 3| which extend down from the top of the cabinet into the space between the adjacent kegs, as shown.

The upper portions of these heat exchanger sections are enclosed in suitable ducts 32 with which the outlet of a blower 33 connects so that the air is positively circulated over the heat exchanger.

The inlet of the blower has an air duct 34 connected thereto from which branches 35 rise to extend into the faucet standards and divide the same into the two passages 2i and 22, as in the construction previously described.

Consequently, suction is established at the upper end of each faucet standard which draws cold air up from the cabinet interior to keep the beer lines cold throughout their entire length.

From the foregoing description taken in connection with the accompanying drawings, it will be readily apparent that this invention provides a practical manner of positively circulating cold air through the hollow faucet standards of a direct draw beer dispenser to insure all portions of the beer lines being kept at the same temperature.
