Claim 3

In a carbonated beverage dispenser, the combination comprising, a bottle for holding CO2 gas under pressure, a regulating spool valve connected to said bottle, means for biasing the spool of said valve into an idle position, a first precharge container in the form of an outer annular cylinder connected to said spool valve, an inner porous ceramic cylinder concentrically positioned within said first precharge chamber for holding a water-syrup charge therein, said inner porous ceramic cylinder spaced from said first precharge container outer cylinder to provide an annular space therebetween, a cooling reservoir tank containing a water-syrup liquid mixture connected to said spool valve, said tank positioned in said dispenser at an attitude adapted to allow a predetermined charge of the liquid mixture to drain therefrom into said first precharge container porous ceramic cylinder via said valve when said spool is biased in its idle position, a second precharge chamber connected to said spool valve; actuating means for moving said spool to an initial position whereby said spool valve connects said CO2 bottle with said second precharge chamber allowing a measured quantity of high pressure CO2 gas to expand from said bottle and occupy said second precharge chamber, said actuating means causing further movement of said spool whereby said spool valve connects said second precharge chamber with said annular space of said first precharge container such that the high pressure CO2 gas passes through said porous ceramic cylinder into said first precharged chamber to carbonate the liquid mixture therein, said actuating means causing further movement of said spool whereby said spool valve connects said first precharge chamber with a dispenser nozzle whereby a predetermined volume of carbonated liquid mixture is dispensed by said nozzle into A glass or the like.

Claim 4

In a carbonated beverage dispenser, the combination comprising, a bottle for holding CO2 gas under pressure, a regulating spool valve connected to said bottle, means for biasing the spool of said valve into an idle position, a first precharge container in the form of an outer annular cylinder connected to said spool valve, an inner porous ceramic cylinder concentrically positioned within said first precharge chamber for holding a water-syrup charge therein, said inner porous ceramic cylinder spaced from said first precharge container outer cylinder to provide an annular space therebetween, a cooling reservoir tank containing a water-syrup liquid mixture connected to said spool valve, said tank positioned in said dispenser at an attitude adapted to allow a predetermined charge of the liquid mixture to drain therefrom into said first precharge container porous ceramic cylinder via said valve when said spool is biased in its idle position, a second precharge chamber connected to said spool valve; actuating means for moving said spool to an initial position whereby said spool valve connects said CO2 bottle with said second precharge chamber allowing a measured quantity of high pressure CO2 gas to expand from said bottle and occupy said second precharge chamber, said actuating means causing further movement of said spool whereby said spool valve connects said second precharge chamber with said annular space of said first precharge container such that the high pressure CO2 gas passes through said porous ceramic cylinder into said first precharged chamber to carbonate the liquid mixture therein, said actuating means causing further movement of said spool whereby said spool valve connects said first precharge chamber with a dispenser nozzle whereby a predetermined volume of carbonated liquid mixture is dispensed by said nozzle into A glass or the like.

Claim 5

In a carbonated beverage dispensing device, in combination; a portable cabinet, a water-syrup liquid mixture reservoir tank positioned within the upper portion of said cabinet, a removable CO2 bottle positioned within said cabinet and normally being charged with CO2 gas under pressure, a first precharge water-syrup container and a second precharge CO2 container positioned within said cabinet, a spool valve comprising a valve body having a bore therein positioned on the front wall of said cabinet below said tank, said bore having a plurality of paired upper and lower ports communicating with said bore at spaced locations therealong, a spool slidably received in said bore and having a plurality of longitudinally spaced lands thereon for sealing engagement with said bore defining a plurality of reduced diameter annular grooves between said lands; said spool having a coaxial stem portion extending through said cabinet front wall allowing an operator to depress said spool in said housing bore, biasing means tending to maintain said spool in an outwardly idle position thereof along said bore, one of the pair of ports connecting said tank with said first precharge chamber by means of one of the spool grooves when the spool is in its idle position, whereby a predetermined volume of the liquid mixture exits from said tank into said first precharge chamber, upon said spool being initially depressed another pair of ports connecting said CO2 bottle with said second precharge chamber by means of one of the spool grooves whereby a measured quantity of high pressure CO2 gas expands to occupy said second precharge chamber, upon said spool being further depressed another pair of ports connecting said second precharge chamber with said first precharge chamber by means of another one of the spool grooves whereby the liquid mixture in said first precharge chamber is carbonated by the predetermined volume of high pressure CO2 gas from said second precharge chamber, upon said spool being further depressed another pair of ports connecting said first precharge chamber with a dispenser nozzle in said cabinet by means of another one of the spool grooves whereby a predetermined volume of carbonated liquid mixture is dispensed by said nozzle into a suitable container.

Claim 6

In a carbonated beverage dispensing device, in combination; a portable cabinet, a water-syrup liquid mixture reservoir tank positioned within the upper portion of said cabinet, a removable CO2 bottle positioned within said cabinet and normally being charged with CO2 gas under pressure, a first precharge water-syrup container and a second precharge CO2 container positioned within said cabinet, a spool valve comprising a valve body having a bore therein positioned on the front wall of said cabinet below said tank, said bore having a plurality of paired upper and lower ports communicating with said bore at spaced locations therealong, a spool slidably received in said bore and having a plurality of longitudinally spaced lands thereon for sealing engagement with said bore defining a plurality of reduced diameter annular grooves between said lands; said spool having a coaxial stem portion extending through said cabinet front wall allowing an operator to depress said spool in said housing bore, biasing means tending to maintain said spool in an outwardly idle position thereof along said bore, one of the pair of ports connecting said tank with said first precharge chamber by means of one of the spool grooves when the spool is in its idle position, whereby a predetermined volume of the liquid mixture exits from said tank into said first precharge chamber, upon said spool being initially depressed another pair of ports connecting said CO2 bottle with said second precharge chamber by means of one of the spool grooves whereby a measured quantity of high pressure CO2 gas expands to occupy said second precharge chamber, upon said spool being further depressed another pair of ports connecting said second precharge chamber with said first precharge chamber by means of another one of the spool grooves whereby the liquid mixture in said first precharge chamber is carbonated by the predetermined volume of high pressure CO2 gas from said second precharge chamber, upon said spool being further depressed another pair of ports connecting said first precharge chamber with a dispenser nozzle in said cabinet by means of another one of the spool grooves whereby a predetermined volume of carbonated liquid mixture is dispensed by said nozzle into a suitable container.
