3 Claims. (o1. 225-,-12)
This invention relates to beverage dispensing apparatus in which pipe connections extend from the beverage containers to the dispensing faucets and :air or carbonic gas pipes extend from a pump or tank to the beverage containers for supplying the pressure needed to raise the beverage from the containers to the dispensing faucets. More especially, this invention relates to arrangements for cleaning the beverage piping.
The pipe cleaning operation in such dispensing apparatus in general use today, is performed with special portable apparatus which necessitates disconnecting the pipe system from the beverage containers for cleaning and flushing. The operation is usually performed when the beverage dispensing apparatus is not in use and when it is performed during service hours service is necessarily discontinued during the pendency of the operation. This method is poor at best; it does not encourage or permit of sufficiently frequent and sufficiently thorough cleaning operations to insure at all times the best sanitary and palatable conditions. It also causes a serious loss of beverage contained in the pipe lines extending from the containers to the dispensing faucets. In addition to these serious shortcomings, this method is inconvenient and costly. Y
To overcome these objections, methods and apparatus have been invented for cleaning the pipe lines without causing loss of beverage and without disconnecting the pipe lines from the beverage containers. Invariably, however, these new methods and apparatus are complicated and impractical. In most cases the beverage inthe pipe lines is saved by driving it back into the containers before the cleaning operation is started. This is an undesirable practice for the reason, among others, that the beverage from the unclean pipes would have a deleterious effect upon the beverage in the containers. Thus, despite the great shortcomings of the first mentioned method, the last mentioned methods and apparatus have not been generally accepted.
The principal object of the present invention is to provide a practicalmethod and means for encouraging and permitting the frequent cleaning of the pipe system at any time during as well as outside of service hours, without loss of beverage, without the necessity for returning the containers, without the necessity for disconnecting the pipe linesfrom the beverage containers and without the employment of special portable apparatus.
Another object is to provide apparatus of the character described, having easily accessible controls located in the immediate vicinity of the dispensing faucets.
A further object is the provision of safety control means which function automatically to prevent accidental fouling of the cleaning and flushing system, as for example, the passage of cleaning fluid into the beverage containers.
These and other objects are attained by mechanism illustrated in the accompanying drawing in which- Fig. 1 is a front elevation of the entire system showing its application to a beer dispensing unit and showing one of a plurality of beer barr-els connected to one of a plurality of beer dispensing faucets;
Fig. 2 is a partly diagrammatic view of the system as a whole;
Fig. 3 is a sectional view of the master valve controlling said system;
Fig. 4 is a sectional view of a diaphragm safety valve used in the automatic safety control mechanism of said system; and
Fig. 5 is a sectional view of another diaphragm safety valve used in the automatic safety control mechanism of said system.
The present invention is shown in the drawing as applied to beer dispensing apparatus. The
invention has equal application. to other types of beverage dispensing apparatus in which compressed air or carbonic gas supplies the pressure for raising the beverage from the beverage containers, through a pipe system, to the dispensing faucets.

Referring now to Fig. 2, a cross coupling 20 is connected to the tap of one of the barrels by direction against the tension of the sprin until means of the usual assortment of pipe and pipe it rests against seat '65, all passage of fluid up couplings.

It is equally clear that when one of the ports of the cross coupling by means 5 the fuller ball is in its normal elevated position, of the usual series of pipe and pipe couplings is there is communication between the pipeline leada pipeline 25 which leads to the coil 28 in the ing to the beer barrel on the one hand and pipecooling system and connected to the other end lines 25 and 36 on the other hand through their of the coil by means of the usual type of conrespective pipe fittings.

. pipeline 30 is at all times prevented by check valve 29. When all of the remaining beer is dispensed, the pipes are ready for the cleaning operation.
The safety apparatus of the system functions as follows: It has been said that double valve 52 is normally kept open. Compressed air, therefore, normally passes through main line 40, branch line 4|, valve 52 and pipes and pipe connections 5| into the right hand compartment of diaphragm valve 50. The pressure of said compressed air against the diaphragm 53 causes said valve to open. It will be noted that the pressure of the compressed air against diaphragm 53 is equal to the pressure of the compressed air in safety air line 35 against diaphragm H when the master valve 3| is opened. Let us now assume that there is a failure of the compressed air supply during the cleaning operation. This would cause diaphragm valve 36 to open and. Since diaphragm valve 50 controls the flow of water and cleaning fluid into the system, no water or cleaning fluid will pass into the system when the pressure of the compressed air is so low that diaphragm valve 35 is caused to open and communication is effected between pipelines 3D and 25 on the one hand and pipeline leading into the beer barrel on the other. Water and cleaning fluid are thus prevented from entering the beer barrel and spoiling the beer. When the system is not in use, or when it is desired to replenish the cleaning fluid supply in tank 60, valve 52 may be closed. A vent 52a, in said valve opens when the valve closes, and the air in pipeline 5| escapes. This relieves the pressure on the diaphragm in valve 50. The fluid may be drained off, when desired, through drain cock 60a.
The invention hereinabove described may be modified in a number of ways without departing from the basic principles thereof. Essentially, the invention is intended to provide a practical method and means of exhausting beverage from the pipeline system before cleaning said system and to provide a practical and simple meth- 0d and means of cleaning the system. All of fluid pressure forces a beverage out froma beverage container into and through a pipe line system, and thence into and through a dispensing faucet, a diaphragm valve controlled by pressure for closing on the pipe line systorn from the beverage container, air pressure means for forcing the beverage that remains in the pipe line system into and through the; dispensing faucet for dispensing, valve means for admitting cleaningfluid under pressure into said pipe line system after the remaining beverage therein contained has been dispensed, and a second diaphragm valve controlled by fluid pressure for controlling the flow of the cleaning fluid into the pipeline system, and means closing said second diaphragm valve when the first diaphragm valve accidentally opens.
