COOLING APPARATUSv FOR LIQUIDS.
SPECIFICATION forming part of Letters Patent No. 739,595, dated September 22, 1903.
Application filed November 13, 1902. Serial No. 131,144. (No model.) l
To @ZZ whom it may concern:
Be it known that I, HUGO FLGGE, innkeeper, asubject of the King of Prussia, Ger- Erfurt, in the Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Cooling Apparatus for Liquids, of which the following is a specification.
My invention relates to cooling apparatus for liquids; and the object of my invention is to provide an apparatus by means of which the carbonio-acid gas used in an apparatus for supplying beer or other similar liquids under gaseous pressure can at the same time be also used for the purpose of cooling `the liquid to be served out, this device therefore doing away with the necessity of cooling the liquid by means of ice, as hitherto was usually the case. A
The principal feature of my cooling apparatus is the arrangement of a spiral pipe, which is securely fixed within a chamber containing water or other similar iluid. The carbonio-acid gas which iiows through this spiral pipe cools the water surrounding the pipe to such an extent that it begins to freeze. Consequently the liquid to be served out, which is contained in air-tight glass cylinders and which are surrounded by the freezing water, can be cooled in this manner to any required degree.
One of the various forms in which my apparatus can be carried out is shown in the drawings accompanying this description.
Figure 1 shows a lvertical cross-section on the line A B, Fig. 3. Fig. 2 shows a vertical cross-section on the line C D, Fig. 3. Fig. 3 shows a horizontal section on the line E F, Fig. l. Fig. 4 is a plan view, and Fig. 5 isa front elevation of Fig. 1. The apparatus as shown in Figs. 1 to 5 of the drawings is only intended forone kind of liquid. On the otherhand, the apparatus as shown in Figs. 6 to 8 can be used to cool simultaneously two different kinds of beer. Fig. 6 shows a vertical cross-section on the line G H, Fig. 7. Fig. 7 shows a horizontal section on the line .l K, Fig. 6. Fig. 8 is a plan view of Fig. 6. Fig.
9 is a diagrammatic view of the whole apparatus.
The cooling apparatus 1 (shownl in Figs. 1 to 5 of the drawings) -consists of two cylindrical air-tight closed vessels 2 and 3 of glass, porcelain, stoneware, or any other similar ma terial, which are arranged one within the other. These vessels are hermeticall y closed at the top and bottom by means of two plates 4 and 5.
The top plate 4 is provided with a domeshaped cover 6, which may be made so as to unscrew. The places where the top and bottom plates 4 and 5 joinV the cylindrical vessels 2 and 8 are made to fit asl tightly as possible by means ofrubber packing 7. The top and bottom plates 4 and 5, as well as the dome-shaped cover 6, are secured as tightly as possible to the cylindrical vessels 2 and 3 by means of bolts 8. A spiral pipe :1; is arranged in the cylindrical vessel 2, which is filled with pure water. The place where the spiral pipe o; passes through the top platel 4 and enters the cylindrical vessel 2 is also made to t as tightly as possible by means of packing. The spiral pipe a: isbent back at its lower end and passes upward through the center. The inlet end 9 of the spiral pipe which is closed by means of a stop-cock 10, as well as the outlet end 11, extends beyond the plate 4into the dome-shaped cover 6. The
`cooling-chamber 13 is filled with water by means of a funnel 12 and can be emptied at any time by means of an outlet-valve 14.
`When it is intended to use the apparatus 1, the cock 10 is opened and carbonio-acid gas iiows from the carbonic-acid-gas reservoir 15 into the spiral pipe x.A The gas passes through the pipe and then flows into another pipe 16 by way of the outlet end 11'. (See Fig. 9.) The pipe 16, ifdesired, can be arranged in such a manner as to pass through a box-shaped receptacle i7, in which are kept bottles that are required to cool. vSaid pipe 16 is connected with a carbonic-acid-gas-storage tank 18, which is in turn connected with the beer-barrel 22, from which the beer is forced by gas-pressure to the cooling apparatus 1. The carbonio-acid gas which passes through the spiral pipe fr causes a very con IOC siderable cooling of the Water surrounding it. If the carbonio-acid gas is allowed to circulate through the spiral pipe for any length of time, ice will be found to have attached itself to the spiral pipe x.
If it is desired to ll the chamber 19 between the cylindrical vessels 2 and 3 with beer, wine, or any other similar liquid', it is only necessary tofopen the valve 20, (see Fig. 9,) when the carbonio acid gas will pass through the pipe 2l and enter the vessel 22, containing the said beer, Wine, or other liquid as soon as the valve 23 has been opened and cause the liquid by its pressure to flow into the chamber 19 by way of the pipe 24.
The pipe 24, which passes through the bottom plate 5 of the cooling apparatus 1, is bent round as soon as it has passed through the plate 5 and extends for a short distance in a horizontal direction. This horizontally-arranged end 25 of the pipe 24 causes the liquid through which it enters the chamber 19 to do so with a rotating circling motion. It is due to this motion that the liquid does not commence to freeze and that the carbonicacid gas with which the liquid is impregnated does not escape. To enable the air to escape automatically from the cooling-chamber 19 as soon as the liquid to be cooled begins to flow into the chamber, the top plate 4 is provided with a cock, or better still with a iloating valve 26, which closes as soon as the liquid reaches it. An outlet-pipe 27, with a cock 28, passes through the dome -shaped cover 6 and the top plate 4 into the coolingchamber 19.
For the purpose of observing and being able to regulate at any time the temperature of the liquid to be cooled before it is served a thermometer 29 is arranged within the cooling-chamber 19. If the cylindrical vessels 2 and 3 are made of glass, the thermometer 29 can be seen from the outside. lf, on the other hand, the material of which the cylindrical vessels are made is of porcelain, stoneware, or any other non-transparent material, a glass inset or window must be arranged in the wall cf the cylindrical vessel at some suitable place, by means cf which the temperature can be taken.
The cooling apparatus l, as shown in Figs. 6 to 8 of the drawings, which, as already stated, is intended for two different kinds of liquids, is provided with two outlet-pipes. It consists of ive cylindrical Vessels 30, 31, 32,
33, and 34, arranged one within the other, which are hermetically closed at each end by a top and bottom plate 4 and 5. The top plate 4 is provided with a dome-shaped cover 6. All parts are securely connected together by means of bolts 8.
The spiral pipe oc, with the stop-cock 10, is arranged in a similar manner to the one described in the apparatus shown by Figs. 1 to 5 of the drawings, but with this dierence that the Water-chamber 13, within which the spiral pipe is arranged, acts as a coolingchamber in two opposite directions-that is to say, it brings about the lowering of the temperature in the two cooling- chambers 36 and 37, which are separated by it fromeach other and which serve for the cooling of the two different kinds of liquids.
The cylinders 30 and 3l are separated by an air-space 35, which serves the purpose of preventing theinside cylinders being aected by the temperature of the outside air. y
The apparatus as shown in Figs. 6 to 8 differs further from that shown in Figs. 1 to 5 inthe shape of the spiral pipe m. The latter in this instance is not bent back at the bottom end and carried again upward, but runs straight on toward the bottom plate 5, through which it passes with two outlet ends; but this variation is of no importance. The only purpose of the dome-shaped cover 6 is to improve the appearance of the apparatus.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is In an apparatus for cooling beer, wineand the like, a cooling vessel havinga coiled pipe arranged therein and connected with a source of gas-supply under pressure, a gas-storage tank connected with said coiled pipe, a cask for containing the liquor to be cooled, a pipe connecting said cask with the gas-storage tank, a pipe connecting said cask with the cooling vessel, and an outlet from said cooling vessel for withdrawing the cooled liquor therefrom.
