LIQUIDCOOLING DEVICE.

Specification of Letters Patent.

Patented Novias, 1907.

Application filed January '7.1907'. `Serial No. 351.104.

lBe it known that I, ADOLPH KOCH, a citizen of the .United States, 'residing at Pasadena, in the county of Los Angeles and State of California, have invented new and useful Improvements in Liquid-Cooling Devices, of which the 'following is a specification.

My invention relates more particularly to portable liquid cooling devices and an object thereof is to provide means whereby liquid may be cooled as drawn off from a liquid receptacle secured to thel outside of the cooling device.

Another object of my invention is to provide a device whereby it is possible to replace the liquid receptacle with another holding a different liquid with little trouble or inconvenience.

Another object is to provide a device, the lower chamber of which may be utilized as a refrigerator While the upper chamber may be uid receptacle being removably secured to the outside of the cooling device, thus greatly increasing the capacity of the refrigerant chamber.

A further object is to provide a device that is economical in construction and efficient in operation.

I accomplish these objects by means of the device described herein and illustrated in the accompanying drawings, in which Figure 1."- is a side elevation of my improved device partly broken away. Fig. 2.- is a front elevation of my improved device partly broken away. Fig. 3.- is a transverse section taken on line 3 3 of Fifr. 2. Fig. 4.- is a longitudinal section througl the outlet end of the liquid receptacle, showing the construction of the outlet valve. Fig. 5.- is a transverse section .taken on line 5-5 of Fig. 4.

Referring to the drawings, 10 designates a cooling receptacle composed of an upper chamber 1 1 provided with a drain pipe l1', which is designed to hold the refrigerant, preferably ice, and a lower chamber 12 designed for the accommodation of perishable erably restingon the bottom thereof is a coil inside walls with tin. This coil of pipe preferably rests on end pieces 14 secured to the bottom of the chamber and which are inclined transversely from one side to the other, so as to provide for a sufficient fall from the inlet of the coil to its outlet. 16 of the coil is in screw threaded engagement with an' inlet pipe 17 which projects through the front wall of the receptacle. The outer end of this inlet pipe y17 projects upwardly and is provided on its outer end` with an annular flange 18, which is adapted to engage the inwardly couphng 20 which is in screw threaded engagement with the receptacle holder 21, which in this instance is' shown as cone shaped so as to correspond with the configuration of the open end of the liquid holdmg receptacle 22, which may be formed of any desired material. The inner face of the cone-shaped portion of the holder 21 is provided with a flexible pad 21 to guard the lower end of the liquid receptacle against possible injury.

interposed between the outer end of inlet pipe 17 and the lower end of the receptacle holder is a rubber gasket 23 so .as to form a liquid tight joint. The neck 24 of the receptacle holder 21 passes through an aperture 25 in a bracket 26 which is rigidly secured to the outer face of the cooling receptacle, a se't screw 27 preventing it from turning. The upper end of bracket 26 is provided with an a( justable slide arm 23 which projects outwardly therefrom and is provided with a screw threaded aperture 29, through Which passes an adjusting screw 30, which has on its lower end a clamp 31 adaptedl to engage the up er end of the liquid holding receptacle, an to hold it firmly 1n place in the receptacle holder 21.

The liquid holding receptacle may be of any desired form, such as large demijohns of water that are supplied to offices and families.

When it is desired to place the liquid holding rece tacle in its operative relation to the The inlet end turned flange 19 of a coolingy evice, the usual cork stopper is rst removed and a valve 32 is secured to the mouth of the receptacle. This valve consists preferably of-a cylindrical elastic body 33 adapted to fit over the neck of the receptacle, one of its ends being closed and provided with an outlet ort 34. On the inner face of the closed en is a metallic plate 35 which is provided with a similar port 36 which registers with port 34. Movably secured to the outer face of valve 32 by means of a rivet 37 is a metallic plate 38 which is provided with a port 39 .similar in sha e to the ports in the cylindricalelastic bo y of the valve and the metallic plate 35.

`tacle with the ports 3 4 and Metallic plate 38 is provided on its periphery with a pluralit of lugs 39 which are adapted to engage a p uralityiof vertically disposedY grooves 40 on the,inner surface of the neck of the rece tacle holder 2T.

The out et end of the coil 13`is in screw threaded engagement with a faucet 41 which projects through the front of the coohng receptacle 10 below the inlet to the pipe coil 13. This .faucet is provided with a valve stopper 42 which is adapted to engage a seat 43 near the inner end of the faucet and inside of the upper chamber 11, and is controlled by valve stem 44 which is connected on its buterrend to the handle 45 by means of which thestopper is operated. The reason for pro,- viding the faucet with a stopper near the inner endv is to insure the withdrawal from the faucet of liquid that has been cooled orv that is in close proximity to the refrigerant.

If desired, the liquid holding receptacle could be permanently secured to the cooling device and to the coil, having an inlet in its top so that liquid could be introduced to the receptacle as required.

The operation is as follows :#When it is desired to cool-the liquid contained in a receptacle the stopper is first removed and the valve 32 is secured to the mouth of the recep- 39 ,out of register, as shown in Figs. 4 and 5. The bracket 29 is then turned to one side and the liquid receptacle is placed in the holder, the lugs 39 engaging the grooves in the neck of the receptacle holder. The receptacle 22 is then turned slightly so as to bring the

ports

34, 36, and 39 into register with each other, ythe liquid flowing through the coil 13 to the faucet 41, from which it is drawn when desired.

It will be seen from the foregoing description that I have roduced an economical and an efficient coo ing device whereby large quantities of liquid may be cooled as needed without encroaching upon any of the space of the cooling receptacle. l

Having described my invention, what I claim is 1. In a device of the class described, a refrigerant holder, a pipe coil therein having an inlet and an outlet, an apertured liquid receptacle support attached to said refrigerant holder and forming the inlet end of said coil, a liquid receptacle adapted to be supported in said support, andhaving a valve adapted to be operated by movement of the liquid receptacle on its su port to permit discharge of the contents o the liquid receptacle into the coil as desired; and a valve at the outlet end of said coil'.
