APPARATUS FOR CARBONATING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 706,115, dated August 5, 1902.

Application filed August 9, 1901. Serial No. 71,462. (No model.)

To all whom it mag concern:

Be it known'that'l, ARI RULF, a subject of the German Emperor, and a resident of Brussels, Belgium, have invented certain new and useful Improvements in Apparatus for Carbonating Liquids, of which the following is a specification.

This invention relates to apparatus for carbonating liquids; and it has'reference particularly to that portion of the mechanism of such apparatus whereby the mixing of the gas and liquid'to be'c'arbon'ated is effected.

The invention consists in animproved form of saturater constituting that portion of the carbonating apparatus particularly referred to above, constructed substantially as will be hereinafter described and finally embodied in the clauses of the claim.

In the accompanying drawings I have shown one form of embodiment of theinvention.

Figure l is a vertical sectional view of the saturater, and Fig. 2 .is an elevation of the complete apparatus.

The saturater, Fig. 1, is composed ofa cylinder a, closed at both ends-andthe lower end of which is connected, by means of a pipe I), to the carbonic-acid-gas reservoir, while the top of said saturater is connected, by means of a pipe c, to an automatic compression pump actuated, for instance,= by the pressure of a water-conduit. Said pump forces Water under a pressure corresponding to the pressure of the carbonic-acid gas into the smallreservoir d, arranged under the top of the cylinder and within the latter, and thence through small passages e into pipes I f, forming concentric.rings and to which said passages are connected. Said concentric pipes fare arranged in close proximity to the surfaces of concentric cylinders g, arranged within the saturater to alternate with the pipes and sustained on a small grating h, resting on the bottom of the cylinder, by means of suitable supports 2', forming a free space between the grating and the bottom of the saturater. The annular pipes f are provided with minute openings 70, through which water is spread upon the external and internal surfaces of the concentric cylinders 9. Thus, the saturater being filled with carbonic-acid gas, said water will be completely saturated with the gas, perfect saturation of the water with the gas heinggreatly' facilitated by virtue of the fact that I providethe cylinders g with roughened surfaces. The thus saturated liquid drops upon thebottom of the saturater and flows into the receptacle Z, arranged'under the latter, fromwhere it may be drawn off into bottles.

It will be understood that the annular pipes f may be connected directly to the pipe 0, in which case the reservoir (1 is omitted, or the cylinders 9 may be made of any other form and arrangement. I

Referring now to Fig. 2, on the lower part of the frame m is arranged an automatic compression-pump connected by means of the pipe 0 to a suitable water-conduit. The pressure of the water in the latter operates said pump, which compresses said water and forces same through the pipe 0 into the saturater a, arranged on the frame on and connected by means of the pipe b to the reduction-valve 12, secured on the carbonic-acid gas reservoir q. The pressure of gas flowing out from the latter is reduced by said reduction-valve to a low pressure corresponding to the pressure of the liquid inthe saturater, into which said gas is brought through the pipe I); Arranged within receptacle Z is a tube 0', the upper end of which is connected to a tube 25, connected to the cocksof the drawing-off apparatus to. When there is no water-conduit available for actuating the compression-pu mp, Water may be forced into the saturater by the pressure ofthe carbonicacid gas itself. To this end the pump is omitted and substituted by a receptacle, into which liquid is introduced through a valved pipe extending from any reservoir. Said receptacle is connected by means of another valved pipe to the carbonic-acid-gas reservoir provided, to this end, with a second reduction-valve. Thus the liquid contained in the receptacle will be under the pressure of carbonic-acid gas and forced into the saturater. When all the liquid is forced out from said receptacle, the latter is again filled by closing the carbonic-acid-gas admission valve and opening the liquid-admission valve.

Having fully described myinvention, what I claim, and desire to secure by Letters Patent, is-

1. In a carbonating apparatus, the combination of an inclosed casing having a discharge-outlet for the carbonated liquid and in lets for the gas and the liquid to be carbonated, a plurality of concentric annular tubes arranged in said casing, communicative connection between said tubes and the liquid-in- 1et,,and concentric cylindrical bodies a1ternating with said tubes and each open at one end, said tubes and the cylindrical bodies being arranged in close proximity to each other and the former being perforated adjacent said cylindrical bodies, substantially as described.

2. In a carbonating apparatus, the combination of an inclosed casing having a discharge-outlet at the bottom for the carbonated Witnesses:
