Abstract
Abstract Disclosed is an apparatus for carbonating water or other beverage comprising a carbonating tank for charging the water with carbon dioxide and for dispensing the carbonated liquid. The apparatus also includes a reservoir tank disposed above the carbonating tank for storing the liquid to be carbonated. The two tanks communicate with each other through a valve which is controlled by a float disposed in the carbonating tank. The float valve is arranged to open and permit the liquid to flow from the reservoir tank into the carbonating tank when the latter is substantially empty and the pressure therein has been reduced by withdrawal of the carbonated liquid sufficiently to allow the liquid to flow into the carbonating tank by gravity.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
193 words
An apparatus for carbonating liquid such as water or other beverage comprising: a carbonating tank having a liquid inlet port for introducing liquid to be carbonated, a liquid outlet port for dispensing carbonated liquid, and a gas inlet port for introducing pressurized carbon dioxide gas into said carbonating tank; a reservoir tank disposed above said carbonating tank for storing the liquid to be carbonated, said reservoir tank having a liquid outlet port; a conduit connecting said outlet port of said reservoir tank with said liquid inlet port of said carbonating tank; and valve means responsive to the level of the liquid in said carbonating tank for opening said conduit to permit liquid stored in said reservoir tank to flow into said carbonating tank under the influence of gravity until said carbonating tank becomes substantially filled, for closing said conduit thereupon, and for maintaining said conduit closed thereafter to prevent the flow of liquid from said reservoir tank into said carbonating tank until said carbonating tank is substantially empty of liquid and the pressure of the gas therein is less than the pressure of the liquid at said outlet port of said reservoir tank.
Claim 2
Independent Claim
193 words
An apparatus for carbonating liquid such as water or other beverage comprising: a carbonating tank having a liquid inlet port for introducing liquid to be carbonated, a liquid outlet port for dispensing carbonated liquid, and a gas inlet port for introducing pressurized carbon dioxide gas into said carbonating tank; a reservoir tank disposed above said carbonating tank for storing the liquid to be carbonated, said reservoir tank having a liquid outlet port; a conduit connecting said outlet port of said reservoir tank with said liquid inlet port of said carbonating tank; and valve means responsive to the level of the liquid in said carbonating tank for opening said conduit to permit liquid stored in said reservoir tank to flow into said carbonating tank under the influence of gravity until said carbonating tank becomes substantially filled, for closing said conduit thereupon, and for maintaining said conduit closed thereafter to prevent the flow of liquid from said reservoir tank into said carbonating tank until said carbonating tank is substantially empty of liquid and the pressure of the gas therein is less than the pressure of the liquid at said outlet port of said reservoir tank.
Claim 3
Dependent Claim
13 words
Apparatus according to claim 1 wherein said valve means is a float valve.
Claim 4
Dependent Claim
31 words
Apparatus according to claim 2 including a perforated pipe connected to said gas inlet port and extending along the bottom of said carbonating tank for dispersing the gas in the liquid.
Claim 5
Dependent Claim
41 words
Apparatus according to claim 3 wherein said reservoir tank has a liquid inlet port and a float valve for opening and closing said inlet port of said reservoir tank in accordance with the level of the liquid in said reservoir tank.
