  • a counter assembly 175 Positioned below collar 176 is a counter assembly 175 having an arm 177, thereon. As can be seen in FIG. 6, collar 176 will deflect arm 177 in the direction of arrow 162 as rod 164 reciprocates in cylinder 52a during the dispensing operation. Each deflection of arm 177 is recorded in the counter assembly 175 thereby to record the number of drinks dispensed.
  • conduit 120a is connected to cylinder 52a. This connection can be seen in FIG. 8 as passing through a suitable grommet to a port 180 in communication with the lower chamber 158.
  • Conduit 50a also communicates with the lower chamber 158 through a radially extending port .182, which in turn communicates with a bore 184, which extends axially through head 146.
  • a movable valve member 186 is mounted in the bore 184 is of a size to provide a small annulus 188 between the exterior of the valve member 186 and the bore 184.
  • Annulus 188 communicates with a radially extending port 190, which is in turn connected to the annulus 168 which is to be selectively connected to the lower chamber 158.
  • the annulus 188 is sealed above the port 182 by means of O-ring seal 192 carried by the valve member I86 and below port by means of O-ring seal 194 carried by the valve member 186.
  • valve member 186 has a discharge passageway 196 extending axially along the valve member 186 from an end thereof up to a point above O-ring 192 and then radially to the periphery of-valve member 186 to communicate with the annulus 188.
  • the discharge passageway 196 is sealed from the lower chamber 158 by an O-ring seal 198, which is carried by the valve member 186.
  • FIG. 12 The operation of cylinder 52a will be described by reference to FIGS. 12-14.
  • piston 150 is shown in its at rest position prior to the initiation of the dispensing and metering operation.
  • momentary depression of button 100a of valve 98 admits enough carbon dioxide gas through conduit 120a and port 180 into chamber 158 to cause the piston 150 to move in the direction of arrow 200.
  • O- ring seal 165 will move out of the annular passageway 168 as illustrated in FIG. 13 thus placing the conduit 50a in gas communication with the lower chamber 158 through port 182, annulus 188, port 190 and passageway 168.
  • valve member 186 vents the gas from the lower chamber 158 and the piston 150 is moved in the direction of arrow 162 by the force of spring 160 shown in FIG. 7. This causes piston 150 to move in the direction of arrow 200a until piston 150 reaches the position illustrated in FIG. 12 where the underside of piston 150 has forced valve member 186 to slide through the bore 184 to seal passage 196 by O-ring 198. Also, as piston 150 returns to the position illustrated in FIG. 14, the O-ring 165 will again seal annulus 168.
  • a vacuum is created in the chamber 156 to draw a measured volume of liquid into chamber 156 through check valve 132a and conduit 130a.
  • the stroke of pistons 150 and the volume dispensed by cylinders 52a-f is varied.
  • the stroke will be shortened and the volume discharge will be decreased.
  • the stroke will be lengthened and the volume discharge increased.
  • the volume of liquid dispensed can be set as desired.
  • piston 150 divides its cylinder into two sections, the gas section and the liquor section.
  • the pistonspring holds the piston at the gas end of the cylinder with the liquor end full of liquor.
  • the first port is always under gas pressure. This port leads gas around the gas piston and to the space between the piston shaft, and the piston shaft hole thru the end plate. This space is sealed at the outside of the end plate with an O ring in the end plate, and at the inside with an 0" ring on the shaft.
  • the second port leads directly into the space between the piston and the end plate and receives gas from the control valve only when the valve button is pressed.
  • control cam When the control cam reaches the gas piston as in FIG. 14 it moves the piston which does two things: (I) it switches the gas source from feeding the gas section to dumping it outside; and (2) it opens an additional hole to help dump more gas from the gas section for a faster return. As the gas pressure drops in the gas section, spring pressure forces the piston back toward the end plate. By means of a set of back checks the spout tube is sealed and liquor from the bottle is sucked into the liquor section. When the piston reaches the end plate it moves the gas piston back to its original position and the cycle is complete.
  • control valves are shown mounted in a single housing 60.
  • event service may be required on one or the other but not both sets of valves at any given time, it may be desirable separately to mount units and 98 rather than in the single housing as shown.
  • liquor metering unit may be used separately from the other beverage dispenser, as in a bar setting. In this case, a plurality of bottles could be manifolded for increasing the run time before the supply needs to be replenished.
  • a fluid dispenser which comprises:
  • a supply line adapted to lead from a fluid storage vessel into a first chamber of said cylinder
  • a fluid dispenser as set forth in claim 1 including a control valve positioned in said closed end in the flow path from said first gas pressure line to said cylinder to move into said cylinder in response to contacting said stop and moves out of said cylinder in response to contacting said piston to thereby control flow of gas from said first pressure line to and from said cylinder.
  • a fluid measuring and dispensing apparatus of the type for mixing and dispensing carbonated and noncarbonated liquids into a container, comprising in combination:
  • first means for mixing and dispensing carbonated liquids comprising a tank adapted to contain water, said tank being connected to and pressurized by said supply for forcing water in said tank to flow through a water discharge line, a receptacle adapted to contain at least one syrup container, said receptacle being connected to and pressurized by said supply for forcing a syrup to flow through a syrup discharge line, and a selectively operable mixing and dispensing valve means separately connected to said supply, said syrup discharge line, and said water discharge line for mixing and dispensing said syrup, water and carbonated liquids to thereby produce and dispense carbonated liquids into said container,
  • second means for selectively measuring and dispensing additional liquids into said container comprising at least one liquid receptacle, said dispensing means comprising a piston mounted in a cylinder with a piston rod extending through a closed end thereof, a supply line adapted to lead from said at least one receptacle into a first chamber of said cylinder, a discharge line terminating in a dispensing nozzle and connected into the first chamber of said cylinder, a first gas pressure line leading to a second chamber of said cylinder through a normally closed valve which is opened by a movement of said piston in the chamber, a second gas pressure line leading to the second chamber of said cylinder through a manual control valve to initiate the movement of said piston thereby opening said normally closed valve upon an opening of said manual valve, a stop on said piston rod below said closed end for venting the second chamber of said cylinder to atmosphere, and resilient means in said cylinder to return said piston to an initial position to close said normally closed valve.
  • a fluid apparatus as set forth in claim 4 including a control valve positioned in said closed end in the flow path from said first gas pressure line to said cylinder to move into said cylinder in response to contacting said stop and moves out of said cylinder in response to contacting said piston to thereby control flow of gas from said first pressure line to and from said cylinder.
