My invention relates to apparatus for cool in liquids delivered from taps, faucets, or drinking fountains and the object of the invention in general is to provide a cooling coil of eificient design and construction which may be used advantageously within a small tank or compartment in connection with a refrigerating unit of standard construction.

In the accompanying drawing, Fig. 1 is a perspective view of a drinking fountain cabinet containing my improved cooling ap paratus, and Fig. 2 is a top view of the same cabinet, on a larger scale, with the cover or top removed. Fig.3 is a vertical sectional 1 view longitudinally through the upper part of the cabinet on line 3- 3 of Fig. 2. Fig. 4 is a vertical sectional view transversely of the cabinet on line 4-4 of Fig. 3. Fig. 5 is an enlarged sectional view yertically of the- 2 upper. end of one of the end manifolds of the cooling coil.

As shown in the drawings, the invention has been applied to adrinking fountain cabinet 1 havin a removable top orcover 2. An overflow owl 3 on top 2 contains a jet, bubbler or other device 4 adapted to deliver a stream of drinking water at an inclination, or perpendicularly, into the bowl. A valve 5 is used in the present apparatus to control the dischargeof water from jet 4. A cooling coil 6 made of copper pipeis connected to the body of valve 5, and this coil is confined-within a rectangular receptacle or tank 7 which is lined upon its outside with cork or other insulating nfaterial 8. A refrigerating unit 9 is mounted upon one end wall of the tank,

and the supporting head 10 of this unit is provided with circulating pipe connections ,11 for the refrigerating medium of whatever kind or nature used. The cylindrical body of unit 9 extends horizontally into the upper part of tank 7, and loops 12 for the refrigerant depend from the body toward and into the. bottom of the tank, the whole unit being usually submerged within a body of water I maintained within the tank at auniform level by an overflow pipe 13. A cooling apparatus of that generaltype is not broadly new, but in order to obtain efficient cooling effects anda relatively large storage capacity top,

' lowing the sides of a supply of drinking water within a smaller cabinet than that used heretofore, I have devised a new and useful cooling coil 6 which is of U -shape when viewed from the whereby both sides and the inner end of the refrigerating unit 9 are flanked and enclosed by the coil, although spaced apart therefrom. The coil is made of separate sections of pipe, each of which is bent into loop or U-shape, and these sections of pipe are superposed andtheir open ends or extremities 15 welded to hollow upright members or manifolds 1616. Two such manifolds are used each having a series of reverted or return bend channels 17; and the ends of the I pipes are connected to the manifolds in such a manner that the several pipe sectionsprovide a single continuous passage from a supply pipe 18 to a discharge pipe 19. Thus, s pp y of manifold 16, and the water passes therefrom into one end of the top or highest pipe section and thence through said section (foland across one end of the tank) to the top of the second manifold 16,

and thence downwardly through the first reverted channel 17 to the intake end of the next pipe section immediately below the top section. The water now passes through this pipe section back to the first -manifold 16 I and thence downwardly through a reverted or return bend channel in this manifold to the next lower pipe section, and so on circuitously through all the remaining pipe sections and return bends until the water passes from'the bottom of the first manifold 16 into thebottom pipe section 14-which has its outlet end or discharge portion 19 bent upwardly to permit a connection to be made with the valve 5 instead ofwith the second manifold 16. The refrigerating unit and the cooling coil are both submerged in water or other. suitable solution in the tank, and

cooling of the drinking water in coil 6 is effected. by maintaining the water in the tank at arelatively low temperature. T

A cooling coil constructed as delineated has a relatively large storage and cooling capacity; it permits a smaller tank and cabinet to be used than heretoforefit takes up pipe 18 connects with the upper end 70 i v 1,77o,e7s

only a narrow space within the tank; it parallels three sides of the tank and spans the inner end of the refrigerator unit; it permits easy assembly of the parts within the tank; it ma be made of short'pieces of pipe the mani olds may be cast; and the cost of the entire outfit ,lSCOIlSidGIfiblY reduced compared with prior structures and practices, while the cooling efliciency is greatly increased.

What I claim, is: P 1. A cooling apparatus, comprising a cabinet containing a water tank,a water-distributing fixture mounted upon said cabinet, .a refrigerating unit extending into said tank,

an overflow pipe for said tank, a water cooling and circulating coil of superposed loop shaped pipe sections extending along one side of said tank and thence across one end and back along the other side, a supply pipe connection for the upper pipe section, and a discharge pi connection for the bottom section and sai water-distributing fixture.

2. A cooling apparatus, comprising a water tank, a water-distributing fixture, a refrigerating unit extendin into said tank, a water circulating coil 0 superposed loop shaped pipe sections extending along one side of said tank and'thence across one end and so back along the other side, a supplypipe connection for said-coil and a discharge pip'e connection for saidcoil and said water distributing fixture.

3. A coolin apparatus, comprising a reas ceptacle, a re igerating'unit' extending into a said receptacle, a series of superposed U- -sha d pipe section enclosing the free end of saidfefrigera'ting unit and connected in series at their corresponding ends, to form a con- 40 tinuous coil, a suppl pipe connection-for one end-of said coil an a discharge connection for the other end of said coil.

4. A coolin apparatus, comprising a receptacle, a re igerating unit extending into 15 said receptacle, a series of superposed pipe sections loosely fitted into said receptacle and enclosing the extending portion of said refrigerating unit, said pipe sections having open ends, spaced apart from each other,

00 means to connectsuperposed open ends of adjoining'sections to form a continuous coil,

. and supply and discharge connections for said co f In testimony whereof I aflix my sifiiature.
