14 Claims.

This invention relates to beverage dispensing devices and is particularly directed to a system for dispensing beer and cleaning beer pipes.

An object of this .invention is to provide a system of the character described having means for returning the beer in the cooling pipes to the beer kegs, and means for flushing the pipes with water, the construction including a highly improved device controlled by movement of a single member at the bar for operating the entire system.

A further object of this invention is to provide a compact system of the character described, comprising comparatively few and simple parts, which shall be relatively inexpensive to manufacture, easy to assemble and install, smooth and positive in operation; and withal practical and efficient to a high degree.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

In the accompanying drawings, in which is shown one of the various possible illustrative embodiments of this invention,

Fig. 1 is an elevational view of a system embodying the invention;

Fig. 2 is a cross-sectional view taken on line 22 of Fig. 1;

Fig. 3 is a side elevational view of the structure shown in Fig. 2;

Fig. 4 is a side elevational view of the controlling valve mechanism forming part of my improved system and showing the valves in crosssection; and

Figs. 5, 6 and 7 are cross-sectional views of the valves in various positions thereof.

Referring now in detail to the drawings, I designates the floor of a bar-room or the like, in which the beer is dispensed, and l I designates the floor of the cellar beneath. Mounted in the cellar are the beer kegs l2, an air pump E3 to supply air for producing pressure in the beer kegs, and an air tank [4 connected to the pump l3 by piping iTaTfor maintaining air under pressure.

Mounted on the floor I6 is a bar l containing a usual refrigerating unit for cooling the cooling coils E6. The coils it are connected by pipes l6ato faucets H which are interconnected by a pipe l8. The cooling coils are likewise connected by pipes !6b, as at H), to a pipe 23. Mounted on any suitable support within the cellar is a multiple valve 2|] comprising an annular valve casing 2| having a passage 22 connected to said pipe 23 leading to the cooling coils [6. The valve casing 2| is also 5 provided with a passage 24 to which there is connected a piping 25 communicating with the usual rods 26 projecting into the beer kegs. Said valve casing 2| is further formed with a passage 26 diametrically disposed with respect to the passage 22 and connected to a pipe 2? to which there is supplied water under pressure from any suitable source. A passage 29 is further provided in said valve casing substantially directly opposite the passage 24 and connected to a drain or outlet pipe 30.

Disposed within the casing 2! is a valve cook 32 having three parallel through passages, to wit, a central passage 33 adapted to interconnect the

passages

23 and 21 in one position of said cock, a passage 34 adapted to interconnect the

passages

22 and 24 in another position of said cock, and. a passage 36 adapted to interconnect the

passages

22 and 29 in still another position of said cock. It will be noted that when the'passage 34 interconnects the

passages

22 and 24 the

passages

33 and 36 are closed. When the passage 33 interconnects the

passages

22 and 26 the

passages

34 and 36 are closed, and when the passage 36 interconnects the

passages

22 and 29 the

passages

34 and 33 are closed. The valve cook 32 extends beyond the casing 2| and attached thereto is an actuating arm 38 normally maintained in the position shown in Fig. 4 of the drawings with the passage 34 interconnecting the

passages

22 and 24, by a coil tension spring 39. The spring 39 may be connected to one end of the arm 38, and fixed at the other end thereof to any suitable support.

Mounted in any suitable manner on the bar I5 40 and preferably in a position easily accessible to an operator at the bar, is a valve 42 comprising an annular valve casing 43. The casing 43 is provided with a passage 44 interconnected by a pipe 45 to the air tank I4. Interposed in the 45 pipe 45 and adjacent the valve casing42 is a oneway air valve 46 permitting air to flow from the tank [4 to the passage 44 but preventing return of air to the air tank. Said valve casing 43 is further formed with a passage 4! connected by 50 ing 43 may be further formed with a passage connected to an air exhaust pipe 5| provided with an air exhaust valve 52. Said passage 4'! is preferably mid-way between the

passages

44 and 50. The valve casing 43 is further formed with a passage 54 to which there is attached piping 55 connected to the faucets l1.

Rotatably mounted within the casing 43 is a valve cook 55 having a curved passage 51 adapted in the position shown in Fig. 4, to interconnect the passages 44 and 41. Said cock 55 is formed with a second. curved passage 58 closed in the po sition shown in Fig. 4 and adapted to interconnect the passages 4-4 and 54 upon 'rotating'the valve cock through a predetermined. angle. When the cock is turned to bring the passage 58 in position for interconnecting said

passages

44 and 54, the passage 57 will interconnect the passages 41 and 50. Said passage 53 is further adapted to interconnect the passages 44 and 41 upon rotating the valve cock through another predetermined angle. In said last position, the passage 51 is closed. Said valve cock is formed with a third curved passage 59 closed in the position of Fig. 4 and in said last two positions of the valve cock, and adapted to interconnect the

passages

44 and 54 upon rotating the valve cock through still another predetermined angle. In said last position of said valve cook the passages 5'! and 58 are closed.

Attached to the cock 55 and extending from one side thereof is an axial shaft 66 projecting from the valve casing, and attached'to said shaft 60 is an arm 6| provided with a curved portion 52 having a curved slot 52a concentric with respect to said valve casing. Interconnecting the arm 38 of the lower valve 20 with the slotted member 62 is a connecting rod or link 53. The upper end of the link is provided with a pin. 54 projecting through the slot @211 in said slotted arm. Extending from the. valve cock 55 in a direction opposite to the shaft 60 is an axial shaft 66 to which there is attached a handle 67. The handle 51 is provided with a hand grip 68 to which there is pivoted a lever 69 pressed by a spring ll! against a peripheral portion of the valve casing. Said valve casing maybe provided with a plurality of spaced notches H receiving a an edge of the lever for retaining the valve cock scribed. Beginningwith the parts in the position shown in the drawings, the air tank is connected through the passage 51 in the valve 42 to to the beer kegs and supplies sufficient pressure to said kegs to permit flow of beer through the pipe 25 through the valve passage 34 and pipe 23 into the coils l5. Upon opening the faucets li', beer may be dispensed in the usual manner.

Should beer be left remaining in the pipes and coils l5 overnight or for long periods, the beer in said pipe would become stale so that several glasses of beer must be tapped off 'to get rid of the beer kegs or barrels.

in a counterclockwise direction, looking at Fig. 4 to bring-the passage 51 to a position where the same interconnects the passages i'l'and 55. The

passage 58 will in this position interconnect the passages 44', and 54 and the pin54will contact the left or outer end ofthe slot 62a. The valve 25, however, will not be turned due to the lost motion or pin and slot connection between the link 83 and the arm 62. With the valve in such position, the pressure within the beer kegs will be reduced due to flow of air through the pipe .8 to the passage 5? in the valve 42 and through the exhaust air valve 52.

The air from the tank I4, however, will pass through the pipe 45, through passage 58 and into the pipe 55, forcing the beer in the coils I6 back through the pipe and passage 34 to the pipe 25, and h nce to the beer kegs.

To clean the beer pipes after the beer has been forced back to the beer kegs, the valve cock 56 is turned further in a counterclockwise position, looking at Fig. 4 of the drawings, to the position where the valve passages 44 and 41 are interconnected through the passage 58. During this movement the arm 62 will lift the connecting rod 63 to cause counterclockwise movement of the valve cock 32 for bringing the passage 33 into communication with the

passages

22 and 26. Water from the pipe 21 may then pass through the passage 35 to the pipe 23 and up through the beer coils. Upon opening the faucets the water will be let out, thus thoroughly Washing the beer coils. During this operation, air will pass to the beer kegs, since the passage 53 interconnects the pipe 45 with the pipe 48, thus keeping the beer properly charged and preventing the same from becoming flat.

To drain the water from the coils, the valve cook 55 is rotated further in a counterclockwise direction, looking at Fig. 4 of the drawings, to bring the passage 59 in position for interconnecting thepassage 44 with the passage 54. In this position the

passages

58 and 57 are closed. .At the same time the connecting rod or link 63 is further lifted to cause further rotation of the valve cock 32, bringing the passage 36 into position for connecting the passage 29 with the passage 22. The water in the coils may then be drained by gravity, out through the pipe 30.

The pipes, however, are more effectively cleaned by reason of the fact that the pipe 45 leading from the air tank is connected by passage 59 with the pipe 55, and air may pass through the pipe 55 to the coils, thus forcing any drops of Water or other material out from the pipe 23 and to the drain pipe 35. The notches H are properly located for retaining the lever 69 and handle 61 in the respective angular positions. The lever 59 may then be depressed and the handle rotated back to the original position shown in Fig. 4 of the drawings to again force the beer to the cooling coils I6.

It will be understood that the interconnected 1 valves may be operated by any suitable electromagnetic devices or electric motor, instead of the manual operation illustrated in the drawings.

Instead of using compressed air and an air pump, any other suitable supply of gas under 7 pressure may be substituted, for example, carbon dioxide under pressure, It 'will therefore be understood that the term .air under pressure in the specification and claims will be taken to mean any suitable gas under pressure. g

It will thus be seen'that there is provided adevice in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments mightbe made of the above invention, and as various set forth or shown in the accompanying drawings, is to be interpreted as illustrative and not in a limiting sense.
