THOMAS E. FRY, OF OAKLAND, CALIFORNIA, ASSIGNOR OF ONE-HALF TO CHARLES W. HAMERTON, OF OAKLAND, CALIFORNIA.

LIQUID-COOLING DEVICE.

To all whom it may concern:

Be it known that I, Tnomxs E. FRY, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Liquid- Cooling Devices, of which the following is a specification.

My invention relates to acontinuous liquid cooling apparatus.

It consists in a combination of parts, and in details of construction which will be more fully explained by reference to the accompanying drawings, in which Figure l is a vertical sectional view of a liquid cooling device embodying my invention. Fig. 2 is a horizontal sectional View on the line 00 w of Fig. 1.

It is the object of my invention to provide an economical apparatus for continuous cooling of liquids. in the present device I have shown it adapted to cool a liquid which may be transferred under pressure from one receptacle to another.

A is a cooling chamber which is preferably made globular in form in order to re sist any degree of pressure that it may be desirable or necessary to apply to the passing liquid. This container is fitted into an exterior chamber 2 having a removable upper portion 2 and a cover 3. The receptacle A has an opening upon the lower side which is screw-threaded, and to this may be connected the inlet and discharge devices.

In the present case I have shown an inlet pipe 4 connected with any source of supply as, for instance, a cask containing beer under pressure which it is desired to cool when it is drawn for customers. The inlet portion at, and the outlet or discharge portion 4* may be conveniently formed in a single structure; the inlet end being adapted as before described to connect with the source of supply, and the outlet end may have connected with it a delivery faucet 5; the contiguous ends of the two passages l4 meeting in a transverse T 6 which may be screwed or otherwise secured to the lower partof the globular chamber A. This portion 6 has interior screw-threads, and a plug 7 is adapted to screw into these threads and the lower part of the transverse portion. From a point substantially on a level with the bottoms of the passages 4, this plug is cut away on opposite sides as at 7, and this cut Specification of Letters Patent.

Serial No. 405,788.

away portion extends upwardly substantially into the chamber A.

The lower end of the plug 7 may have an index pointer or handle 8 which projects horizontally in such position as to indicate the position of the separating diaphragm 7. WVhen in proper position for use this diaphragm is turned to stand transversely across the meeting ends of the passages 4t so that liquid delivered through the passage 4 will be divelted upwardly into the chamber A, and will thence pass downwardly upon the opposite side of the diaphragm 7 into the discharge passage 4, and thence to the faucet 5.

The chamber 2- 2 may be filled with ice packed upon the top of the chamber A, and as the ice melts, the Water will [ill the lower part of the chamber, thus inclosing the globular chamber in a refrigerating body of liquid which will rapidly cool the contents of the chamber A.

The cover 3 may be taken off the top for the addition of ice when desired, and by removing the upper part 2 of the chamber, it will be easy to obtain access to the globe, and to remove it after the transmitting pipes have been disengaged from the bottom.

9 is an overflow pipe extending to near the top of the lower part of the inclosing casing 2, so that water will always be discharged before rising sufliciently to leak out through the joint between 2 and 2 lVhen employed to cool beer, or other gascontaining liquids, it may be found desirable to draw off a portion of the gas before the liquid is served. For this purpose I have shown a pipe 10 extending from near the top of the interior of the chamber A down to connect with the diaphragm 7 which has a small hole made through it, and discharging outside as shown. This is controlled by a needle valve 11 which is provided with a manipulating milled head or other device so that whenever it is desired to draw off a portion of the interior pressure, by opening the needle valve this can be accomplished. If it is desired to entirely drain the chamber 2, this is effected by a drain pipe and cock as at 12. \Vhen the diaphragm 7 is turned to bring its cut away portion substantially parallel with the passages 4, 4, it leaves a direct passage to the faucet 5, and liquid can then be drawn without being diverted into the refrigerating chamber.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. An improved liquid cooling device having in combination, an exterior casing adapted to contain a refrigerant, a cooling chamber within said casing, inlet and outlet pipes arranged below the casing and having their adjacent portions connecting with said chamber, a turning plug at the junction of said inlet and outlet pipes, said plug being threaded on its exterior to engage corresponding portions of the adjacent ends of the inlet and outlet pipes, and said plug having two of its sides cut away to form channels which extend lengthwise of the plug and open at their upper ends into said chamber, and means whereby the plug may be turned to stand transversely across the meeting ends of the pipes whereby liquid delivered through the inlet pipe will be diverted upwardly along one of the cut-away sides of the plug and into the chamber and will thence pass downwardly upon the op posite side of the plug into th outlet pipe.

2. An improved liquid cooling device comprising an exterior casing adapted to contain a refrigerant, a chamber inclosed by said casing and having an opening in its lower end, inlet and outlet pipes having adjacent ends meeting substantially in a vertical plane of the opening in the bottom of the chamber, said opening and said adjacent end of the pipes being internally threaded,

' and a turning plug between the adjacent ends of the pipes and in line with the opening in the chamber, said plug being externally threaded to engage the thread on the adjacent ends of the pipes and also the threads in the bottom opening of the chamber, said plug having two of its sides cut away to provide passages for conducting the liquid from the inlet pipe through one of said cut-away portions into the chamber and thence delivering the liquid from said chamber through the other cut-away portion into the discharge pipe.

3. In an apparatus of the character described, a cooling chamber, a pipe connecting the preliminary liquid container with a. discharge faucet, a transverse member fitting the bottom of the cooling chamber having a screw-threaded plug closing the lower part, and a diaphragm extending up into the cooling chamber and having longitudinally extending channels in its opposite sides connecting at their upper ends with the cooling chamber whereby liquid may be diverted through the chamber, an exterior handle or guide by which the diaphragm may be turned to allow liquid. to pass directly to the discharge and to indicate the position of the diaphragm, and means including a pipe and a passage through the turning plug whereby the gas in the cooling chamber may be reduced.

4. In an apparatus of the character de scribed, a cooling chamber and an inclosure adapted to contain a refrigerant, a pipe having a passage leading from the preliminary container to atlischarge faucet, a transverse screw-threaded passage connecting said pipe with the cooling chamber, a diaphragm turnable to allow a liquid to pass directly to the faucet, or to divert it into the cooling chamber, and thence .to the discharge passage, a passage through said diaphragm, a needle controlling valve at the bottom, and a pipe extending from the passage up to the top of the interior of the coolingchamber.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
