1 Claim.

The present invention relates to apparatus for impregnating water, such as that used in carbonated beverages, with CO2.

One of the objects of the invention is to provide a carbonator which, with a comparatively small water container, may impregnate a comparatively large amount of water in a relatively short period of time. To this end, in the present invention, I provide a container in which a large volume of C02, commonly referred to as gas, is maintained, preferably under pressure, and the water to be carbonated is delivered within this container in the presence of the gas, in a fine spray. In passing through the gas, this fine spray of water will absorb a, large proportion of gas. This initially carbonated water is again re-circulated through a sprayer which delivers the water a second time in the form of a ne spray, the water passing through the gas, thereby absorbing the gas a second time, so that eventually it has absorbed about all of the gas it can take up.

For the purpose of disclosing my invention, I have illustrated an embodiment thereof in the accompanying drawings, in which:

Fig, 1 is a side elevation of carbonator embodying my invention, portions thereof being shown in section;

Fig. 2 is a plan view of for the container;

Fig. 3 is a side elevation thereof;

Fig. 4 is a plan view of the container, with the top removed; and

Fig. 5 is a detail section of one of the spray heads.

, In the embodiment of the invention illustrated, I provide a base I on which the various parts of the carbonator are adapted to be mounted. This base is provided with a hollow supporting standard 2 having a top 3 on which is supported the cylindrical container 4. This container rests on a bottom closure plate 5 and is secured to the standard 2 through the medium of cap screws 6 passing through a ring 'I on the container 4 and into the standard. A suitable packing ring is interposed between the bottom edge of the container cylinder 4 and the bottom plate. The top of the container is closed by a cover 8 secured to the container through the medium of bolts 9 passing through the cover and through a clamping ring IIJ on the cylinder 4. A suitable packing ring is interposed between the top edge of the cylinder and the cover plate 8 to insure a tight packing. This container has arranged therein a plurality, preferably four in number, of spray heads which are disposed at the top of the cyl- Ainder 4. Two of these spray heads II and I2 which may be referred to as the initial spray heads are mounted at the tops of a pair of branch tends Yto hold the heads more or less rigidly in position.

On the underside of the bottom plate y5, I mount a connecting unit 2I which is preferably in the form of a single casting provided on its top surface with an annular flange 22 to provide a recessed surface into which a suitable packing `may the connection casting be tted. This casting is provided with bolt-receiving openings 23 adapted to receive securing bolts- 24 passing through the bottom plate 5 and into the openings, whereby the casting will be secured to the under face of the plate 5, surrounding an opening, corresponding in general in contour, to the casting. This casting is provided with an inlet extension 25 screwthreaded at its bottom to receive an elbow 26 into which is screwthreaded the infeed pipe I5. This infeed pipe I5 is connected by a suitable conduit or pipe 21, through the medium of the elbow 21 and a conduit 28 with a reciprocating pump 29 mountedl on the base I which has an intake opening 30 connected with the source of water supply, whereby, the Water tobe carbonated may be delivered by this pump to the cylinder 4 through the primary spray heads I I and I2.

The inlet extension 25 communicates with a coupling 3l secured on the top of the casting 2I and this coupling is provided with branches receivine, respectively, the threaded ends of pipes 32 and 33 connected, respectively, through the medium of suitable elbows, with the secondary supply pipes I8 and I9 leading to the secondary spray heads I6 and I'I. This extension 25 is provided with an inlet opening 34 connected by a suitable coupling 35 to the discharge side of a centrifugal pump 36 likewise mounted upon the base I. 'I'he intake side of this centrifugal pump is connected by a suitable conduit 3I to an outlet 38 opening into the bottom of the cylinder I4. This outlet 38, as shown in Figs. 2 and 3, is adapted to have connected thereto the pipe coupling or conduit 31, so that, as the water ows through the outlet opening 38, it will discharge into the the cylinder 4 having a reverse bend 44, so that the gas or CO2 will be discharged into the cylinder near the top.A The gas inlet 4I is connected with a suitable CO2 supply, lin any desiredmanner, and preferably the.- gas is maintainedtin the cylinder 4 under pressure.

The fitting 2l is also provided with an air disn charge opening 45 having secured therein an air escape pipe 46. This pipe extends to the topvof the cylinder 4 and is provided with an escape 'head 41T arranged over a bailleplate 48;. Prefer'- ably, this air discharge outlet`45 connected hy a suitable conduit or pipe 49'; with the water inlet check valve. on the discharge side`v of the reciprocatingipump, so thatl as this` valve isoperated', a snift' valve in the. conduit 49 is' openedi to permit discharge of air from the cylinder to atmosphere. y t

A water discharge'y outlet 50 is-al'so provided in the fitting 2|? and'Y this` discharge outlet isy connected through` a suitable valve with the discharge fitting or discharge pipe of' the carbon'ator;`

In operation, the water, through the medium of the reciprocating pump` 29, Vis drawn-from the source' of supply and delivered through the pipe T5 'and' the two branches I3, tothe spray heads l'f' and Il?. By these spray' headsi the water is brokenfup into an extremely ne spray and in this" sprayed form,v falls through the atmosphere of' C02 contained in the container 4. As a result of the breaking' up ofthe water in this extremely fine spray, considerable of the airis released from the watery and, at the same time, the water absorbs alarge quantity of CO2 in the container 4. This water, which is fairly we11 permeated witlfi gast-by the time it reaches the bottom of' the container, then flows through the discharge 38 into the centrifugal pump 36 which again delivers the water through the fitting 25 to the two secondary supply pipes i8 and i9 and through the secondary spray heads I6 and l1. The water is thus again broken up into a ne spray and this fine spray, in falling through the atmosphere of CO2 contained inthe container 4thef-water completely absorbs the C92rv sov that it ifs fully saturated. This saturated water, of course, may be drawn ,off from time to time, as needed, through the discharge opening 50.

Fig. 5, I have illustrated a detail section of one of the discharge heads. As each of the heads ofthe same construction, only one is sufficient. This headcomprises a hollow base 5I connected by a coupling member 52 with its pipe and this-base; on its interior, has a lug 53 adapted, to receive a stem 54 upwardly extending. Surrounding this stem is a coiled spring 55 which rests on the lug 53. 'A cap 56 covers the. topL of thisY springa'nd this cap is adjustedlth-rough the medium of suitable set screws 58 soi that! the spring may be com-pressed toi the desired' degree to thereby vary the sizeof thespray openingsformed' 'between the coils of they springs.
