the handle forming part of the valve control shown in Fig. 11.

Referring now in detail to the drawings, l designates a beer dispensing system embodying the invention, wherein the beer barrels II are located in the cellar on the cellar floor I2, and the bar counter 13 is located on the floor above, being mounted on the floor I4. The system may be controlled by a control mechanism [6 fixed to the bar counter l3. In the drawings there is illustrated a system for dispensing beer from two barrels H, although the same principle may be applied for dispensing beer from and controlling any suitable number of barrels.

The counter 63 may be of any suitable usual 15 construction and is provided with a pair of beer faucets l1 interconnected by pipe I 8. Mounted within the counter are a pair of cooling or beer coils i9, each interconnected through pipe to the pipe l8. Located on the cellar floor I2 20 is an air or carbon dioxide pump 22 having a 7 pressure tank 22a for supplying pressure to the barrels, as explained hereinafter.

Fixed to a support 23 within the cellar is a valve head 25. Said valve head 25 comprises a casting 26 fixed as by bolts 2'! to the wall 23. As will appear hereinafter, the valve head 25 is symmetrical with respect to the mid-section thereof, one side being connected to one of the beer barrels and one of the coils l 9, and the other side being connected to the other beer barrel and the other coil.

The casting 26 is formed with a pair of central valve chambers 28, a second pair of valve chambers 29 disposed on opposite sides of the chambers 28, and an outer pair of chambers 30. The chambers 28 are formed with screw threaded openings 28a in the bottom walls thereof, the chambers 29 with screw threaded openings 290. at the bottom thereof, and the chambers 30 with screw threaded openings 30a at the bottom walls thereof.

Screwed within the openings 28a are plugs 3|. Screwed within the openings 2&0. are plugs 32 and screwed within the openings tea are plugs 33. The plugs 3i and 33 are closed, but attached to the plugs 32 are pipes E i connected to the beer side of the bungs extending into the beer barrels. The

valve chambers

25, 29 and 38 on one side of the valve head communicate through the valve openings 36, Si and 38 with a passage 39 disposed on one side of the valve head, whereas the valve chambers 23, 2S and at on the oppo site side of the valve head are connected to a passage 39, disposed on the opposite side of said 5 valve head and being disposed symmetrically with respect to the first passage 39. The pas- V sages 39 are connected through passages it disposed on the opposite ends of the valve head with pipes M connected to the beer coils I9. The end walls 52 of the valve head are tapped, as at 43, receiving pipes M interconnected, as at 45, and leading through pipe 615 to a water supply under pressure.

As shown in Fig. 8 of the drawings, the pipes at communicate with the end chambers 38. Said end chambers are interconnected through a passage lt disposed rearwardly of the

chambers

28 and 29. The central pair of chambers '28 are interconnected through a pair of rearwardly and inwardly diverging passages til, which meet and communicate with a downwardly extending drain A pair of sliding piston valves 53, having stems 53a, slidably extending through packing glands 5e are provided with discs 55at the lower ends thereof, adapted to close the openings 38 of the valve chambers 28. Coil compression springs 57 within chambers 28 mounted between the plugs 3i and the discs 55 serve to normally retain the valve in closed position for closing the openings 36 and cutting off communication between the chambers 28 and the passages 3%.

A similar pair of valves 59 provided with stems 55 extending through packing glands 62 are provided with discs 53 at the lower ends thereof for closing the openings Bi, and are retained normally in closed position by coil compression springs 69 within chambers 29 and interposed between the plugs 32 and discs 63. A third pair of valves it are provided with stems 3'! extending through packing glands and have discs 73 at the lower ends thereof for closing the openings 38. Said valves are normally retained in closed position by coil compression springs it within chambers 30.

and interposed between the plugs 33 and the discs 53 for normally retaining the openings 38 closed to cut off communication between chambers 3t and the passages 35.

The valve casing 25 is provided with a pair of forwardly extending arms 16 and ll formed with aligned bearing openings at the outer ends thereof, rotatably receiving a shaft 73. Fixed on said shaft it. and disposed between the arms it and ll are a pair of actuating arms 79 bifurcated at the outer endand supporting rollers 8d. The

Z arms i? are aligned with respect to each other and are disposed in the planes of the valves 53.

There is also fixed on the shaft '38 another pair.

of arms 8!] located on opposite sides of the central arm '59 and likewise bifurcated and supporting rollers 82. The arms 8i are aligned with respect to one another and are in the plane of the valve stems SI. Said arms 85 extend, however, in

a direction opposite to the direction on the arm 19, thus being at 180 angular relation to said arms.

There is further fixed on the shaft 18 a third painof arms carrying rollersfiil at the ends thereof. The arms are aligned with respect to one another and are in the plane of the valve The arms 85 are located at an angle As shown the beer valves, project upwardly. The arms 84 V which control the water valves project rearward ly toward the wall 23, and the arms '59 which control the drain valves project downwardly, the shaft l3 being rotatable in aclockwise direction,

aoaaese looking at Figs. 4, 5 and '7, or in a counter-clockwise direction, looking at Fig. 2.

Fixed to the casing 25 anddisposed between the shaft 18 and the valve chambers is a vertical Wall 95 extending between the arms "I6 and 11. Fixed to the wall 9 3, as shown in Fig. 7, as by screws 9 I, are a pair of vertical brackets 92, each having an upwardly extending, bifurcated arm 93 supporting a pivot pin 94. The brackets 92 arealigned with the arms l9 and the valve stems 53a. Pivoted on the pin 94 of each bracket and received within the bifurcated arms is an actuating lever 95 having a tapered downwardly extending projection 96 at the outer end thereof, located above one of the arms It, and an arm 98 formed with a screw threaded opening 99 disposed above one of the valve stems 53a. An adjusting screw I00, provided with a lock nut, is screwed within each opening 99 and adapted to contact the upper end of one of the valve stems 53a.

The brackets 92 are each provided with edge portions IGI serving as a stop to limit clockwise rotation of the levers 95. It will be noted that normally the springs 5'! within the chambers 28' pressing upwardly against the valves 53, retain the levers 95 in the position shown in Fig. '7. However, upon rotation of the shaft I8 the rollers 89 on the arms "I9 will contact theprojections 95- of the levers 95 to'rotate said levers in a counter-clockwise direction and open the valves 53 to permit communication between the chambers 28 and the passages 39.

There is further attached to the wall 90, as shown in Fig. l of the drawings, brackets I02 similar to the brackets 92 and supporting levers 53 similar to the levers $55 and adapted to cooperate with the valves '69 controlling the beer chambers 29. The levers I93 may be actuated by the arms BI for opening the valves E35 and permitting communicaticn between the chambers 29 and the passages 3%.

There is further fixed to the Wall as shown in Fig. 5 of the drawings a pair of brackets-I06 similar to the brackets and I02 and support-' with adjusting screws I08 similar to the adjusting screws H19 and contacting the upper ends of the valve stems II. Each of said levers IO'Iis further formed on one surface thereof with a groove I09 and with an upstanding projection II 0.

Fixed to one side of each lever till is a strip III extending across the groove I09, forming a slot. Pivoted to the projection or lug I I9, as at I I2, andv extending through said slot is a second lever II3 rection for retaining the shoulders II8 against thelevers I81. It will be noted that when the arms 34 rotate in a clockwise direction and engage the underside of the cams IN, the levers [ill will be rotated in a counter-clockwise direction, as shown in Fig. 9 of the drawings, for opening the valves it and establishing communica tion between the water chambers 30 and the passages 39. However, upon'rotating the arms 84 in a counter-clockwise direction, the rollers 85 will contact the lower ends of the levers II3. to rotate the same in a clockwise direction, as shown in Fig. 10 of the drawings, against the tension of the springs I20, permitting the arms 84 to pass said levers without lifting the levers I01 or opening the valves 10.

The shaft 18 extends beyond the arm 11 of the casing 26, as at 18a, and fixed to said extending portion is a sheave I25. Said sheave is provided with a pair of stop lugs I26 and I21 adapted to contact stop members on the arm 11 to limit the angular rotary movement of said sheave in opposite directions. The sheave I25 may be formed with a peripheral groove I28. Received within the groove I28 of the sheave and extending around said groove, is a flexible element I30, the lower end of which is connected through a tension spring I3I to a fixed bracket I32.

The flexible element I30 is attached to a second flexible element I32, described in greater detail hereinafter, through a lost motion device I33. The device I 33 may comprise a strap I34 connected to the lower end of the element I32 and provided with a portion I31 at the lower end thereof having an opening receiving the element I3I therethrough. The upper end of the element I3I is attached to a member I35 provided with a downwardly extending tubular portion I36 receiving the element I3I. The lower end of the tube I36 is normally spaced above the.lower portion I31 of the strap I34 and is retained in spaced position by a coil compression spring I38 received on the tube and interposed between the member I35 and the portion I31 of the strap I34. Should an upward pull be exerted on the flexible elements I32, said element will move a predetermined distance until the portion I31 of the strap I33 contacts the lower end of the tube I36 before movement is imparted to the flexible elements I3I. A lost motion is thus provided between the elements I32 and I3I.

The control device I6 which controls the valve head 25 comprises a casting I40 having a flat plate portion I4I fixed to the side of the bar counter I3, and a valve chamber portion I43, to the bottom end of which there is screwed a plug I44. Screwed to the plug I44 is a pipe I45 connected through pipe I46 to the air inlet ends of the bungs 35. The valve chamber I43 is furthermore formed with a tapped opening in the side wall thereof, to which thereis attached a pipe I41 connected to the tank of the air pump 22. It will thus be noted that communication is always established between the pipes I45 and I41 through the chamber I43. At the upper end thereof the chamber is formed with a valve seat I49, provided with a valve opening I50 communicating with a chamber I5I. The wall of the chamber I5I is formed with a screw threaded opening, to which there is screwed a pipe I52 connected to the pipe I3 and hence through the pipes to the beer coils I9.

Extending through a packing gland I54 on the casting 540 is a valve I55 comprising a valve stem I56 provided with a ball top and having a valve disc I51 at the lower end thereof, adapted to be pressed against the seat I49 by a coil compression spring I60 located within the chamber I43 for closing the opening I 50 to cut off communication between said valve chamber and the pipe I52. The casting I40 further comprises a segmental vertical plate I60 parallel to the plate MI and formed with a notch I6I in the periphery thereof, and with a second notch I62 close to the notch I6I. Said plate I60 is further formed with a third notch I63 disposed substantially 90 from the notch I62 and with a fourth notch I64 disposed substantially 90 from the notch I63 and 180 from the notch I62. The notch I6I will be designated the beer notch, the notch I 62 the return notch, the notch I63 the water notch, and the notch I64, the drain notch, for the purpose hereinafter appearing.

The plates I4I and I60 are formed with aligned bearing openings rotatably supporting a shaft I66. Fixed on one end of the shaft I66 is a. pointer I61 disposed adjacent the outer surface of the plate I60 and adapted to point toward the notches in the periphery of said plate. There is further fixed to said shaft a handle I69 formed with a groove I10 in the outer face thereof. Received within the groove I10 is a lever I1I pivoted to the handle, as at I12, and having an upwardly extending arm I13 and a downwardly extending arm I14. A coil compression spring I15 received within the groove I10 and interposed between the bottom wall of the groove and said arm, normally tends to rotate the lever I1I in a counter-clockwise direction, looking at Fig. 12 of the drawings.

The arm I14 is adapted to be received in one of the notches I6I, I62, I63 or I64, depending upon the angular position of the handle. When the arm I14 is received in one of the notches in the plate I60, the arm I13 projects somewhat beyond the handle. To release the arm I14 from the notch within which it is received, it is merely necessary to grasp the handle and press the arm I13 of the lever against the spring I15 to cause a clockwise rotation of the lever HI. Thereafter the handle I69 may be rotated about the axis of the shaft I66 to align the arm I14 with another notch. The handle I19 may be formed with a bore I to receive a key tumbler I6I of any standard construction, either key or combination operated, and provided with a projection I82 adapted to engage the arm I13 for locking the lever I1I with the arm I14 in one of the notches, for the purpose hereinafter appearing.

There is further mounted on the shaft I66 a sheave I formed with a peripheral groove I9I receiving the flexible element I32. One end of the flexible element I32 is fixed to the sheave I90, as at I93. The casting I 4| may be formed with a guide tube I65 receiving the flexible element I32 therethrough and further receiving a cable protector I96 disposed about the flexible element.

There is further fixed on the shaft I66 a cam I10 having a raised portion I11 and a second raised portion I10 spaced from the raised portion I11.

With the handle I60 in the position shown in Fig. 11, the valve I56 is closed. However, upon turning the handle in a counter-clockwise direction, looking at Fig. 11, the raised portion I11 will press down on the upper ball end of the valve stem I56 to open the valve I55 when the arm I14 registers with the notch I62. Upon further turning the handle 169, the raised portion I11 passes the valve stem and the valve I55 is permitted to close. When the arm I14 reaches the water notch I63, the valve I55 is still closed. However, upon further rotating the handle I69 to the position where the arm I14 reaches the drain notch I64, the raised portion I16 of the cam I10 will press down again on the valve stem I16 and again open the valve I15.

The operation of my improved system will now be explained. Normally the parts are in the. position shown in Figs. 1, 2 and 3. The arm I14 is received within the beer notch I6I and the arms 8i retain the valves 60 in open position, establishing communication between the cham- 7 I01 to open the water valves TI.

bers 29 and the passages 39. Beer from the barrels I I thus flows through the bungs and through the pipes 34 to the chambers 29, and through the passages 39 to the pipes M, and hence to the beer coils I9. Air or gas pressure is supplied to the barrels II through the pipe I which .is connected to the pump 22 through the chamber I43 and pipe I45 to the pipes I46, which are connected to the bungs 35. In this position of the parts beer may be dispensed by merely opening the faucets IT.

To prevent the'beer from becoming stale overnight, the beer may be returned to the barrels by grasping the handle I69, pressing the lever I'II to release the arm I'M from the notch IN and rotating the handle to bring the lever portion I14 within the notch I62. Upon rotating said handle, the valve I 55 will open due to pressure of the raised portion Ill of the cam I10 against the upper end of the valve stem.

Upon opening the valve I55, communication is established between the valve chamber I43 and the pipe I52. Air pressure from the pipe I41 and also air or carbon dioxide pressure from the beer barrel I I passing upwardly through the pipe I45, will be at an equal pressure due to intercommunication through chamber I43. Beer under the same pressure as the pressure in chamber I43 and pipes I35, I41 and I52 fills the pipes 20, coils I9, pipes ii, valve 60 and pipes 34. Thus with a balanced pressure in the system the beer will be allowed to flow downwardly through the coils I9 and through the valve chambers 29 and pipes 34, back into the beer barrels under the force of gravity. It will be noted that upon rotating the handle I69 from the notch I5I to the notch I52, the sheave I90 will rotate through a small angle without, however, causing any rotation of the sheave I25, by reason of the lost motion connection I33.

With the coils I9 empty, should it be desired to flush the coils for cleaning purposes, it is merely necessary to grasp the handle I49 and rotate the same to the position where the arm I'M will enter the notch I53. During this movement the valve I55 will close and the sheave I will be rotated to substantially 90, thus causing the arms BI to move off the levers I03 and permit closing of the beer valves 60. During this move ment the shaft I8 is rotated to the position shown in Fig. 9 where the arms 84 will lift the levers In this position of the parts, beer cannot flow into the passages 39, since the beer valves 60 have closed. Water under pressure, however, from the pipe 46, passes to the pipes 44 and into the water chambers and through said chambers to the passages 39 and through passages 49 to the pipes 4| and upwardly into the coils I9. Upon opening the faucets II, water will flow through said faucets to thoroughly cleanse the coils I9.

When the coils have been sufficiently cleansed, the faucets I? may be closed and the handle I69 thereafter moved to bring the arm I'M to the drain notch I64. This movement of the handle will cause rotation of the sheave I90 and consequently, rotation of the sheave I25 to rotate the shaft I3 to move the arms 84 off the levers I07 to permit closing of the water valves II. The arms I9, however, are moved toan upward position for lifting the levers Q5 and opening the drain valves 53. The valve I55 will also be opened by reason of engagement of the raised portion I18 of the cam I10 with the upper end of the valve stem I 55. Air pressure from the pump and. tank passing through the pipe I41 will then pass through the chamber I43 through pipe I52 for forcing the water downwardly through the beer coils,

through the pipes 4|, passages 39, drain chambers 28, and outwardly through the drain pipe 5|.

After the water has been thoroughly drained from the beer coils, the handle I59 may be rotated back in the opposite or clockwise direction, looking at Fig. 2, to the original position thereof, for closing the drain valves and opening the beer valves. During this movement, the water valves are not open, because the levers H3 are merely tripped, as explained above, without actuation of levers I01. Beer will then again flow from the barrels to the beer coils. The spring I3I pulling downwardly on the cable or flexible element I30, facilitates movement of the handle I39 back to its original position.

It will be noted that the levers III! are each provided with a handle extension 200 adapted to be engaged by a finger of the operator. With this construction, after the beer barrels have been emptied, the water valves may be opened while the handle I59 is in the position shown in Fig. 2 with the beer valves also open. The water may thus flow through the

pipes

45 and 44 through the passages 39 and downwardly through the open beer valves, into the beer barrels for flushing and cleaning the barrels.

To prevent dispensing of beer, the lock IBI may be locked with the portion I'M in either the water notch IE3 or the drain notchIBd. In such positions the beer valves 60 are closed and it is not possible to dispense beer.

It will thus be seen that there is provided a device 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 might be made of the above invention, and. as various changes might be made in the embodiment set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
