  • FIG. 1 shows the general layout of the system wherein a plurality of liquor bottles 10 (generally quarts or half-gallons) are mounted in an upside down position on a manifold assembly 12.
  • a plurality of liquor bottles 10 generally quarts or half-gallons
  • the mounting procedure is as follows. After a full bottle of liquor is uncapped, a rubber nozzle 14 having a base portion 16 and a tip portion 18 (FIG. 4) is fitted over the bottle neck with the base portion 16 of the nozzle in sealed engagement with the bottle. To install a filled bottle on the manifold assembly 12, the tip portion 18 is either bent over or pinched shut by the operator. The bottle is then inverted and the tip portion is slipped inside one of the spout members 20 of the manifold assembly 12. The inside surface of spout 20 is tapered slightly to provide a sealed fit between the spout and the tip portion 18 of the nozzle 14.
  • the bottles 10 are held securely in inverted position on the manifold by means of spring loaded clamp rod assemblies 38 which are adapted to engage and grip the bottom of each bottle 10. As shown in FIG. 3, assemblies' 38 are supported on a channel member 40. Channel member 40 and manifold assembly 12 are fastened together by means of a plurality of bracket members 42.
  • the number of bottles 10 mounted on a single manifold assembly will vary depending on the requirements of the application, space limitations and other factors.
  • the horizontal leg 22 of manifold assembly 12 communicates with the bottom portion of a reservoir 24 by means of anelbow 26, a vertical tube 27, a check valve assembly 28, an elbow 30 and a tee 32.
  • the end of horizontal leg 22 of the manifold communicates with the atmosphere through an elbow 34 and a breather tube assembly 36 as shown in FIG. 1.
  • leg 22 of the mainfold assembly is not exactly horizontal but instead slopes upwardly from left to right (as viewed in FIG. I) at an angle of approximately 2-3.
  • the several filled bottles and manifold assembly can be considered together as a single liquid supply container means 23.
  • valve assembly 28 (FIG. 5) is comprised of a valve body 52, a ball stop member 54 mounted in the lower end of body 52, an O-ring member 56 mounted at the upper end of body 52 and a ball member 58 mounted inside body 52.
  • valve assembly 46 (FIG. 6) is comprised of a valve body 62, a ball stop member 64 mounted in the lower end of body 62,
  • an O-ring member 66 mounted at the upper end of body 62 and a ball member 68 mounted inside body 62.
  • ball 68 moves between an open position (shown in dotted lines) wherein the ball rests on upstanding legs 70 of ball stop 64 and a closed position (shown in solid lines) wherein the ball is seated against the O-ring member 66.
  • a liquid level sensing means 82 is provided for sensing the level of liquid in reservoir 24.
  • a sensing means is comprised of a floating magnetic member 84 and a reed switch means 86 mounted on the exterior of the reservoir as shown at the level at which it is desired to sense the liquid level.
  • floating magnetic member 84 will activate the reed switch to its closed position. This will close an electric circuit and energize some kind of warning device such as a buzzer or warning light located at the dispensing station for the system.
  • FIGS. 8 and 9 show alternative arrangements for sensing the level of the liquid in the system.
  • a cigar-shaped hollow capsule 100 having a magnet 102 therein is positioned in the horizontal leg 22 of the manifold as shown.
  • a pair of grate-like retainer members 104, 106 are provided to retain the capsule in the desired location.
  • a reed switch 108 is mounted adjacent the lower surface of leg 22 and is electrically connected to some kind of a warning device. As the liquid level in the system drops, the capsule I and magnet 102 will descend closer and closer to switch 108 until the magnetic lines of force become great enough to acutate the switch.
  • a plunger-like float 110 is mounted in a cylindrical housing 112 formed in the horizontal leg 22 of the manifold.
  • a flexible membrane 114 is mounted across the top of housing 112 and is positioned to cooperate with an actuating arm 118 of a snap action switch 116 so that when the liquid level drops, float 110 will descend causing membrane 114 to be deflected downwardly by the arm 118. Downward deflection of arm 118 will close switch 116 which in turn will energize a warning device.
  • valve 74 is comprised of a body 88 having three ports, 90, 92 and 94, for connection to the source of compressed air, the reservoir tube 72 and the breather tube 76, respectively.
  • the valve contains a solenoid 96 for actuation of a viewed in FIG. 7 causing ports and 92 to be placed in communication through the valve body and causing port 94 to be shut off.
  • the manifold assembly 12 is first fully loaded with full bottles 10 of liquor.
  • the particular procedure recommended for connecting individual bottles to the spouts 20 of the manifold assembly has been described previously. However, it should be pointed out that the preferred sequence for installing bottles is to start by connecting a full bottle to the spout 20 nearest reservoir 24 which is the spout at the lowest elevation and then to move to the next higher spout and then to the next higher spout and so on until the manifold has been completely loaded.
  • the number of bottles which can be accommodated by the manifold 12 can vary depending on the length of the manifold. For most installations a six-bottle manifold will be suitable.
  • liquid will flow by gravity into the system, filling up reservoir 24 and horizontal leg 22 of the manifold assembly 12.
  • the reservoir is designed so that it will be filled to the top after about six bottles have been installed on the manifold.
  • Tube 72 will start to flll up as additional bottles'above six are added.
  • valve 74 As explained previously, energization of three-way valve 74 will place the liquid in tube 72 and reservoir 24 in communication with a source of compressed air. With dispensing valve 50 energized to its open position, the air pressure applied to the reservoir through valve 74 will cause liquid to flow under pressure from reservoir 24 through tee 32, check valve assembly 46, conduit 48, valve 50 and then out through dispenser 44. It will be appreciated that the flow under pressure from reservoir 24 will cause check valve 28 to close to thus prevent any flow of liquid back into the manifold. It will also be appreciated that upon initial start-up of the system, it will be necessary to actuate switch 88 several times to force liquid through conduit 48 to the dispenser 44. This is particularly true where the elevation of dispenser 44 is at a higher elevation than the system.
  • the amount of pressure applied to the reservoir system 81 during the pressure dispensing cycle will vary depending primarily on the length of conduit 48 and the elevation of dispensing outlet 44 with respect to the rest of the system. For example, with a conduit length in the neighborhood of 200 feet and an elevation differential of about 12 feet a pour of one ounce in one second will require a pressure of about 25 p.s.i.g.
  • the amount of liquid which will be dispensed through dispenser outlet 44 will depend on the length of time valves 74 and 50 remain energized. This time interval can be controlled by the operator or if desired a timer means (not shown) can be employed to provide a predetermined period of energization (irrespective of how long switch 88 is depressed) which in turn will re sult in a predetermined amount of liquid dispensed each time the valves are energized by actuation of switch 88.
  • valves 50 and 74 are de-energized simultaneously causing valve 50 to close and causing valve 74 to cut off communication between the reservoir and the source of compressed air and at the same time vent the reservoir by placing it in communication with the atmosphere through breather tube 76.
  • valve 50 shut off flow of liquid through dispenser outlet 44.
  • air will flow into the manifold system through breather tube 36 and will flow back through horizontal leg 22 of the manifold until it reaches the highest spout at which point it will rise up through the liquid in the bottle, causing a displacement of liquid therefrom.
  • the liquid displaced from the highest bottle will cause liquid to flow by gravity from the manifold through check valve 28 to thereby replace the liquid previously dispensed from the reservoir system 81 through dispenser outlet 44. When the entire system reaches equilibrium, all flow will stop.
  • the dispensed amounts will continue to be displaced from the highest bottle (the bottle closest to breather tube 36) until such bottle is completely empty. After the highest bottle at the end of the manifold is emptied, the next highest bottle will be emptied and so on down the line until all bottles are emptied.
  • check valve 46 in the system is of particular importance in installations wherein dispenser outlet 44 is located at a substantially higher elevation than the rest of the system. This check valve 46 holds the column of liquid back when the line (or lines) to the dispenser station are initially filled and prevents flow back into the system in the event solenoid valve 50 develops a leak or fails to close for any reason.
  • the floating magnetic member 84 and reed switch 82 for alerting the operator when the liquid level in the system reaches a point wherein replenishment is necessary.
  • the reed switch 82 is positioned at an elevation wherein a signal will be given at about the time the next to lowest bottle becomes empty. In the system shown in FIG. 1 this will be accomplished by positioning reed switch 82 at the upper portion of the reservoir as shown.
  • the alternative liquid level sensing arrangements shown in FIGS. 8 and 9 function as described previously to provide the same general objective, namely, to alert the operator when the liquid level reaches a predetermined low level.
  • the dispensing system shown and described provides a relatively simple, easily operated and effective arrangement for dispensing liquor and other liquids.
  • the gravity feed displacement manifold eliminates the need for 'pressurizing the bottles and thus eliminates the possibility of bottle failure and the need for a complex valving arrangement to relieve the system of pressure for purposes of replacing empty bottles.
  • the use of a pressure dispensing cycle for dispensing liquid makes it possible to provide a relatively fast pour wherein the volume dispensed can be accurately controlled.
  • a liquid dispensing system comprising:
  • a liquid supply container means in fluid communication with said reservoir means, said container means being vented to atmosphere;
  • a check valve means interposed between said container means and said reservoir means to permit liquid flow from said container means to said reservoir means and to prevent reverse flow from said reservoir means to said container means;

  • liquid containers are bottles which have been inverted and then connected to said manifold while in inverted position so that the liquid in said bottles will flow by gravity from said bottles into said manifold assembly and then into said liquid dispensing reservoir means.
  • control valve means is comprised of a threeway valve having a first and second position, said valve operable when in said first position to place said liquid dispensing reservoir means into communication with said source of air under pressure and at the same time shut off communication between said reservoir and said reservoir vent means, said valve being further operable when in said second position to place said liquid dispensing reservoir means into communication with the atmosphere through said reservoir vent means and at the same time to cut off communication between said liquid dispensing reservoir means and said source of air under pressure.
