Sept. 1, 1953 A. J. COHEN ETAL CARBONATOR COOLER Filed Nov. 9, 1950 THEIR ATTORNEY Patented Sept. 1, 1953 UNITED STATES PATENT OFFICE CARBONATOR COOLER Abraham J. Cohen, Samuel Levine, and Morris Caminear, New Haven, and Stephen S. Price,

North Haven, Conn.

Application November 9, 1950, Serial No. 194,903

This invention relates to carbonator coolers, and has for one of its objects the production of a simple and efiicient carbonator cooler having a multiple stage water cooling means, and means for spraying cooled water ina manner whereby the water molecules are imprisoned by carbon dioxide for obtaining a superior carbonated Water of high volume content.

A further object of this invention is the production of a simple and eflicient method of cooling and spraying the cooled water to imprison the water molecules within a spray of carbon dioxide to obtain a superior carbonated water of high volume content.

Other objects of this invention will appear throughout the following specification and claim.

In the drawing:

Figure l is a top plan view of the carbonator cooler;

Figure 2 is a central vertical sectional view thereof, certain parts being shown in section;

Figure 3 is a diagrammatic view of the refrigerating coil with its inlet and outlet;

Figure 4 is a diagrammatic view of the primary cooling coil, secondary cooling coil, inlet and sprayer;

Figure 5 is an enlarged vertical detail sectional view of the lower end of the spray assembly.

By referring to the drawing in detail, it will be seen that I designates a refrigerated block, preferably consisting of solid metal cast in a mould and having a refrigerating element such as the coil II embedded therein, as shown in Figure 2. A suitable refrigerant or refrigerating agent is forced through the coil II by means of a conventional type compressor, not shown. An inlet I2 and an outlet I3 provide a connection between the conventional compressor and the coil II to facilitate circulation of the refrigerant through the refrigerating coil II in the conventional manner.

The refrigerated block I0 is provided with a socket I3 preferably centrally located in the block I0, the socket l3 being closed at one end and open at the opposite end thereof. A carbonator cooler storage tank I4 is snugly fitted or embedded within the socket I3 of the block I0 and the outer end of the tank I4 preferably extends beyond the outer end of the block III, as shown in Figure 2.

A primary stage water cooling coil I encircles the refrigerated block It! for substantially its entire length and fits snugly against the outer face of the block I0. Water enters the coil I5 through the supply pipe I6, which of course may 1 Claim. 01. 261-11) be provided at any point with a control valve or shut-off of a conventional type. A secondary cooling coil I! is embedded in the refrigerated block adjacent the storage tank I4, the refrigerating coil II being located intermediate the coils I1 and I5, as shown in Figure 2. The outer end of the primary stage water cooling coil I5 is connected to the outer end of the secondary cooling coil I! by means of a junction pipe I8, a union I9, and a feed pipe 20. The cooled water then passes from the bottom of the secondary cooling coil I? through pipe 2| to the water inlet 22 of the sprayer assembly 23 and then into the adapter 24of the assembly 23. The water is then sprayed into the storage tank I4 in the manner shown in Figure 2. Carbon dioxide enters through connection 25 to which a suitable source of supply 25, shown in dotted lines, is connected in a conventional manner. A suitable relief valve is carried in the connection 28 to provide a suitable pressure relief means. A carbonated water outlet 40 is carried by the tank I4.

One particular type of sprayer which may be used, is that type of sprayer set forth in our copending application entitled Molecular Spray Carbonator Assembly, filed November 9, 1950, Serial Number 194,904. It is important, however, that the sprayer be of a type where the water and carbon dioxide are discharged into the storage tank simultaneously in a manner whereby the water molecules are imprisoned by the carbon dioxide as they are discharged into the tank I4 from the sprayer to obtain a carbonated water of high volume content. However, the present invention relates primarily to the carbonator cooler in combination with a sprayer of a suitable type. The details of the sprayer, however, may be varied within the scope of the present invention.

A conventional level control device 29 is carried within the outer end of the tank I4 below the sprayer 23, to maintain proper level of storage of carbonated water within the tank I4. This level control device is provided with conventional electrodes 30 and 3| which are carried within the adapter 32. No claim is made to the detail structure of the control since the control is of a conventional type well known, and is sold upon the market. The electrodes 36 and 3| are electrically connected by means of wires 33 to a suitable Water pump 34 of any conventional type communicating with the intake line I6 to control the flow of water through the coil I5 and sprayer 23 in conjunction with the level control device 29.

It should be noted that fresh water is pumped into the coil l5, which coil encircles the outer portion of the refrigerated metallic block It] for a primary stage of cooling. The water then passes through the coil I! which is embedded within the refrigerated block for a secondary stage of cooling. The water finally is then sprayed into the stainless steel tank M, which tank I4 also is embedded or fitted within the refrigerated block IE .to provide a third stage of codling. As shown, the refrigerated block In consists of a cast metal block having a refrigerating coil ll embedded within the moulded block, a suitable refrigerant being forced through the {coil M any conventional manner.

The supply of water fed tozthe tank klris electrically controlled at all times by lconven- 1 tional electrodes 38 and 3| of the control device 29. The control device 29 controls the pperatiim of the water pump 34 in any desired conventional manner. The sprayer assembly 23 is provided with a single water discharge element 35. Car- 'bon dioxideis introducedinto theitank J4 through orifices 35 which surround the single :orifice v35 at the :base of the assembly :23. Thesprayernssembly preferably constructed to discharge water into the tan-k :114 with terrific ;force,isu'ch .as is set :forth in our .co-pend-ing application ;a;bove identified, .so as to .create va whirling water znist which :agitates the water within -the carbonator tank :1 4 whenever water-is being'introduced there The water discharge element nomprises the discharge tube 3.1 having the :single discharge aperture 201 orifice .35 at the bottom thereof. A stem 38 'fits in the tube f3! and is provided with angular .or .spiral vanes .39 "to create a whirling water mist which is discharged through ithe-ori: fice :35 into the tank 14 to agitate :thewater :as above-set forth.

.It .should be understood that :oerta'in .detail changes :may be made in the :present structure without departing from the spirit of the invention, 50 long as these changes fall within the scope of the appended claim. Furthermore, .the details of the sprayer and control device may be varied within the scope of the present invention to adapt themselves to the generalassernblydllus- .trated. Having described the invention, what we claim as new is:
