This invention relates to apparatus for treating liquids and has particular reference to means for both carbonating and cooling a liquid without the use of complicated machinery and parts and in such a manner that the simple unit contemplated might be used at home or in locations where there is no electricity or other means available for operating pumps or other equipment that is commonly used for performing the function of so treating liquids.

' One of the most important aims of the instant invention is the contemplation of a unit of the above mentioned character that has as a part of its structure, a carbonating tank and a cooler container, both of which are formed to receive and utilize solidified carbon dioxide or dry ice, the said tank having means establishing communication between the lower portion thereof vand the interior of the main receptacle, whereby carbon dioxide gas may be injected into the liquid contained within the receptacle after a predetermined pressure has been created within the carbonator tank.

A further object of this invention is to provide a carbonator tank for apparatus of the character mentioned that not only is equipped with the aforementioned injecting valve, but also has a relief valve forming a part thereof which permits the escape of gas after the pressure created both Within the carbonator tank and main receptacle has reached a predetermined point established by the release member or spring forming a part of the injecting valve.

Another object of this invention is to provide a carbonating and cooling unit which is equipped with a cooler container that is separate from the carbonating tank, whereby refrigeration of the liquid within the main receptacle may take place even after the solidied carbon dioxide used in carbonating the liquid being treated has been used up. This combination between main receptacle, carbonator tank and cooler container is established because of the necessity for using different amounts of solidified carbon dioxide to efficiently accomplish the desired results.

An even further object of this invention is to provide a novel injecting valve which establishes connection between the interior of the carbonator tank and the receptacle holding the liquid being treated, said valve being formed in a particular manner to establish a non-leaking seal in a manner more fully described in the specifications. Y

The desirability of setting up agitation both within the carbonator tank and main receptacle is also recognized in this invention and there is provided simply formed agitators in the form of rockers that are-affixed directly to the main receptacle so that regardless of how slight the pressure or force exerted when using the unit, it will be moved sufficiently to create an agitation where it will serve to the best advantage.

A large number of minor objects of the invention will appear during the course of the following specification, referring to the accompanying drawing,A wherein:

Fig. 1 is a longitudinal, central, vertical section through a carbonating and cooling apparatus embodying this invention.

Fig. 2 is an end elevation of the same.

Y Fig. 3 is an enlarged. detailed, central, sectional view through the injecting valve forming a part of the carbonator tank, and,

Fig. 4 is a cross section through the said valve, taken on line IV-IV of Fig. 3.

The main receptacle wherein is stored the liquid being treated may be created to present a tank or the like 6, such as illustrated in Figs. 1 and 2. This main receptacle has a liner 8 which is cylindrical, and when forming the unit as illustrated, a trunnion 10 should be aixed at one end on the axis of jacket 8, whereby to co-operate with pipe 12 in a like opposed position, so that when the jacket 14 is moved to position, liner l8 is maintained in spaced relation so that insulating material 16 may be packed between liner 8 and jacket 14.

Obviously, any form of insulated receptacle may be used to contain or hold the liquid being treated so long as it has the property of withstanding an internal pressure and the ability to maintain the liquid at a low temperature, after such temperature has been reached through the medium of hereinafter described cooler container.

A drain and illling opening 18 is provided. whereby to fill or. empty the receptacle when necessary, and a pressure gauge 20 forms a part of the equipment 'and is preferably positioned as illustrated near the top of the receptacle. A draw-oil valve 221s utilized to remove carbonated liquid from within receptacle 6 when the unit is in operation and pipe 12 terminates at a point in the lowest portion of receptacle 6 so that practically all of the liquid may be taken from within the receptacle through valve 22. A cooler container. 24 projects into receptacle 6 from exteriorly thereof and is equipped with a cap 26 that is in screwthreaded engagement with container 24 so that solidied carbon dioxide chunks 28 may be dropped into container 24. This cap is equipped with a relief valve comprising a head 30 and stem 32, the latter being circumscribed by spring 34 that is held under tension by nut 36, positioned within container 24.

A plurality of openings 38 are formed through cap 26 and are closed by head 30 when the valve is in the closed position. Obviously, manipulation of nut 36 will vary the tension of spring 34 so that the pressure required to operate the same may be varied. Under normal conditions it is desirable to require that the relief valve be opened when generated gas within cooler container reaches a pressure of from between twenty to twenty-five pounds. Ihe exceptionally large area of container 24 that is contacted by the liquid being treated within receptacle 6 insures a quick refrigeration and since the material from, which container 24 is made is a good conductor. it is obvious that the solidified carbon dioxide 28 within container 24 will eillciently serve the function of cooling the liquid.

In carbonating liquids through the use of so- A lidiiled CO2, it has been found advantageous to combine with the aforementioned cooler containeracarbonatortank40,suchasillustratedin Fig. i. The specinc construction shown need not be followed, but it is essential that tank 40 have a removable cap 42 which may be used in introducing-the proper amount of dry ice to the interior thereof. In the instance shown and preferred, a relief valve 44 should be provided to form a part of cap 42. Port 46 forms the seat for valve head 48 and spring 50 serves to urge head 48 to the seated position against the pressure of generated gases that are formed within tank 40. A set sleeve 52 is provided to vary the tension of spring 50. and under normal conditions the spring is set tn allow the valve to open when a pressure of from seventeen to nineteen pounds is established. Sleeve 52 is in screw-4 threaded engagement with dome 53 mounted on top of cap 42, and this dome serves as a housing for spring 50. Dry ice chunks 54 are positioned within carbonator tank 40 where they release carbon dioxide gas and it is this gas that is used to charge liquid being treated.

An injecting valve 56 is located in tank 40 at a place where it is entirely within container 6 and this valve is uniquely constructed so that leakage does not occur. The detailed views, Figs. 3 and 4, clearly illustrate the construction of this injecting valve 56. The body 58 thereof is' hollow and in direct connection with the intenor of tank 40 and the lowermost portion of body 58 has a number of holes 60 formed therethrough which terminate in communication with a chamber 62 formed between the parts of the valve 56, as shown in Fig. 3. An annular flange 64 circumscribes the holes 60 and depends from the bottom of body 58. Valve head 66 is integral with valve stem 68 which passes into body 58 throughanopening'lo andamachinetis set up between said stem and walls of the opening. Chamber 62 is always illled with gas under pressure and when the pressure overcomes spring 78, it is obvious that an even opening of the valve takes place without danger of tipping or a holding open at one side.

'Ihe inner end of stem 68 is screwthreaded as at 'I2 to receive nut 'I4 which bears upon spring washer 76 bearing against spring 76, which draws head 66 toward the bottom of body 58. Head 66 has an upstanding annular wall 80 which circumscribes annular ange 64 when the valve is closed, and a resilient gasket 82 within the confines of annular wall 80 bears against the lower annular edge of flange 82 to set up a seal. Thus chamber 62 i's formed. which always has gas under pressure therein when the unit is in operation and through such construction it is obvious that leakage is entirely precluded and no liquid will pass into tank 40 by reason of a faulty seal at injecting valve 56. Annular flange 64 and annular wall 80 do not touch. but are normally spaced apart as shown in Fig. 3.

A pressure of from twelve to fourteen pounds within tank 40 will operate injecting valve 56, and solongas itispossibletochargetheliquidbeing treated with carbon dioxide at this pressure the released gases will pass through injecting valve and into receptacle 6. When the pressin-e within receptacle 6 and tank 40 exceeds fourteen pounds, and climbs to seventeen or nineteen pounds, further charging will be stopped because relief valve 44 will then be brought info play to allow the escape of excess gases being formed.

The structure for agitating the liquid being treated is here illustrated to be a pair of rockers 84 mounted on receptacle 6. When the unit is being used, the slightest handling will cause the same to move and shake" the contents thereof.
