12 Claims.

This invention relates to apparatus for making and dispensing charged beverages, such as carbonated water.

An object of this invention is to provide apparatus of the character described, comprising a charging tank, a chamber in said tank, means to feed gas to said chamber, means to feed water to said tank, and means to simultaneously cut off supply of gas to said chamber and bleed gas from the tank to reduc pressure therein.

Another object of this invention is to provide a highly improved compact and durable apparatus of the character described, which shall be relatively inexpensive to manufacture, easy to manipulate, economical to operate, which will produce a thoroughly charged beverage, and which shall yet be practical and efiicient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts Which will be exemplified in the construction her inafter described, and of which the scopeof application will be indicated in the following claims. v

Fig. 8 is an elevational, cross-sectional view oi the mixing tube illustrating a modified construe ny suitable met andis p ei r o ste lined with block tin. The tank may be of any suitable size, and may be made practically to have a volume of about fifteen gallons. The

tank may be cylindrical, and has a top wall It provided with a central boss l5 formed with an internally screw-threaded central opening l8.-

portion l9, screwed within the opening IS. The

* head 51 is formed with a central through opening 29 communicating with an internally screw threaded opening 2| at its upper end. The upper portion of the head H is formed with three ,equiangularly spaced, radial, horizontal, screw 'threaded openings 22, 23 and 24 communicating at their upper ends therewith, and extending to the lower end of the screw threaded portion 19 of the head.

Fixed within the central opening 2% is an elongated tube 25 to take 01f charged liquid, preferably made of copper, tinned inside and outside, extending down into the tank I2, and terminating somewhat short of the bottom wall l2a of said tank. The upper end of tube 25 terminates short of the central screw threaded opening H in the head l'l.

Mounted on tube 25 is a chamber 21 to break up the gas which is fed to said chamber from the gas tank H, in the manner hereinafter appearing. The chamber 21 comprises a pair of oppositely'facing- annular heads 28 and 29 supporting therebetween a tube 30 made of porous stone or composition of the type which serves to break up gas passing therethrough. Rubber washers 28a and 29a may be interposed between the ends of the tube 33 and the heads 28 and 29. The upper head 28 may be soldered or .otherwisefixed to the tube .25 and the lower head 29 may be clamped against the tube by means of a nut 3| screwed onto. the tube 25 in any suitable manner.

The head'23 may be formed with a through opening 32, aligned with opening 23a in head l'l,

and of the same size as said head. Fixed within opening 23a is a gas tube 34 passing through the opening 32 and projecting substantially half way into the tube 30. At the lower end of the tube 34 is a rubber tube check 35. Tube 34 may likewise be made of copper/tinned inside and utside.

Screwed within the screw threaded opening 23 is a nipple 2311 connected by piping 3'6 to the gas tank H. The tank l I may be provided with the usual pressure gauge Ha; and interposed in the piping 38 is a hand valve 31 and a two way cock 38 which will be described in detail hereinafter.

Upon opening the valve 3! and properly manipulating the valve 88, gas is fed from the tank ll to the piping 38, and through the tube 34 into the chamber 21, for the purpose hereinafter appearing.

Fixed within the opening 24a and extending downwardly therefrom, is a bleeder tube 40 likewise preferably made of copper, tinned outside and inside and terminating somewhat above the head 28.

Screwed within the opening 24 is a nipple 24b connected by piping 4| to the cock 38. The cook 88 is so arranged, as will appear hereinafter, that when the passage of gas from the gas tank to the tube 34 is shut off, gas from the carbonator tank l2 may pass through the tube 48, piping 4! and cock 38 to a suitable exhaust, to reduce pressure in the carbonator tank.

The cook 38 comprises a head 45 formed with an internal, central, tapered chamber 48. The head 45 is formed with a quadrangular cut-out 41a, and received within the tapered opening 48 is a rotary valve member 41 having a transverse through passage 48, and provided with a pin 48 disposed within said cut-out. On the rotary valve member 4'! is a usual handle to rotate the same.

The head 45 has oppositely extending sockets 50 and 5! receiving the piping 35; and a pair of oppositely extending sockets 52 and 53 disposed at right angles to the sockets 50 and 5| and receiving the pipe 4|, and an exhaust pipe 54, respectively. In one position of the rotary valve 41, the iping 36 is open, and when the rotary valve is turned through an angle of 90 degrees, the piping 38 is closed, and the bleeder piping is connected to the exhaust pipe 54.

Screwed within the opening 22 in the head I1. is a nipple 221) connected through a check valve 88 to a pipe 8! leading to any suitable source of water supply. Within the pipe 8| may be interposed a hand valve 62. The check valve 80 permits water to pass to nipple 22b and through opening 22a to the interior of the carbonating tank l2. The check valve 88 may comprise a spring pressed valve stem 65 having a head 68 adapted to seat on the valve seat 61 when the 7 pressure within the tank I2 is above a predetermined pressure. When the cock 38 is turned to bleed the excess pressure from the tank l2, the

pressure is reduced permitting the normal water pressure to open the check valve and admit water to the tank l2.

The operation of the apparatus described thus far, is as follows:

Starting with both tanks being empty, faucet until the carbonator is filled with gas to its maximum pressure. At that time, the faucet 13 is opened to allow the air to escape from the reserve tank I3, and thus allowing it to fill with carbonated water.

To this end, there is screwed into the threaded on the water line.

piping H to the top of tank [3. The carbonated water thus passes from tube 25, through piping 1| into the tank l3. The carbonated water in the tank I 3 is delivered to the faucet 13 through the medium of the pipe 14.

As the carbonated water is drawn oil in dif ferent quantities, the reserve tank and carbonator repeat the above operations automatically.

The hand cook 62 on the water pipe may be closed when it is desired to work on the tank l2. The pressure in the carbonating tank may be maintained at about 120 pounds pressure, to keep the water back by closing the check valve The tank is filled up with water, then the charging of the water takes place, and the carbonated water in the tank is used up. Then, the bleeder is opened to fill up the tank again. The bleeder bleeds gas pressure from the tank to allow water to come into the tank l2, because during the bleeding operation the pressure in the tank l2 decreases below the water inlet pressure causing check valve 88 to automatically open, letting water into the tank again. The water in the tank I2 is never allowed to run below the lower end of tube 25 to prevent escape of free CO from tank l2 to tank IS. The CO gas remains in solution in the water in tanks l2 and I3 because said tanks are kept cold.

If tank l2 would run out of water and allowed the reserve to fill with (10* gas, then the first time the faucet 13 was opened after bleeding tank l2 and hence allowing water to fill said tank, the CO gas in tank l3 would be forced to feed gas into the chamber 80.

'tank l3.

In Fig. 8, there is shown a modified construction of chamber for breaking up the gas. In Fig. 8, the chamber for breaking up the gas, designated by numeral 88 comprises a brass tube 8| tinned inside and outside. Fixed to the upper and lower ends of the tube 8| are heads 82 and 83. The head 83 is formed with a central opening 84 covered by a wire mesh tinned screen 85. The head 82 is formed with a central opening 8'! to receive a tube 88 terminating somewhat below the head 82, for taking off the carbonated water.

The head 82 is also provided with a through opening 89 through which there passes tube 9!] At the lower end of tube 90 is a rubber check valve 9! of usual construction. The inside of tube BI is filled with glass beads 92. The beads are preferably small and are formed with through openings.

Gas is thus fed into the chamber 88, and water comes into said chamber to mix with the gas to carbonate the water which passes upwardly through the tube 88 and thus passes through the head [1 to the reserve tank.

opening 2| in head IT, a nipple I8 connected by It will thus be seen that there is provided a device in which the several objects of this invention are achieved, andwhich is well adapted to meet the conditions of practical use.
