i COOLING DEVICE.`

Application filed February 2G, 1924. Serial No. 695,142.

To all whom t may concern:

Be it known that I, Gus'r T. HAGLUND, a citizen of the United States, residing at Spokane, in Spokane County and State of- VVashington, have invented certain new and useful Improvements in .Cooling Devices, of'

which the following is a specification.

My present invention relates to improvements in cooling devices of the refrigerator type for domestic use wherein a cabinet is utilized and a stream of water is caused to flow through casings therein for the purpose of transferring heat from the interior of the cabinet to the flowing fluid, thus reducing the temperature of the interior of the cabinet. The device of my invention is adapted for usey in connection with water supply of a house or residence and is interposed in the water supply system in 'order that water for domestic uses will pass through the cooler and thus provide an additionaluse without extra expense or increased consumption of As is well known the water contained in the st-reet mains is usually at a much lower degree of temperature than that contained in the house-pipes, and also lower than the atmospheric temperature of the house. from the street main and passes through the cooler, the interior of the cooler is refrigerated for the purpose of preserving foods and provisions in the cooler. My invention consists in certain novel combinations and arrangements of parts in the cooler as will hereinafter be more fully set forth and claimed.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged in accord ance with the best mode I have thus far devised for the practical application of the principles of my invention.

Figure 1 is a digrammatic view showing one installation of the cooler of my invention in connection with the water system of a house or dwelling. Y

Figure 2 is a detail perspective view'of one of the plurality of casings used in the interior of the cooler cabinet.

Figure 3 is a transverse vertical sectional View at line 3-3 of Figure 2.'

Figure 4 is a horizontal sectional view at line 4-4 of Figure 3.

While I have herein referred to the cooler Therefore when the water is drawn as adapted for domestic use, it will be apparent that the invention isapplicable for use in other relations, where a flow of water under pressure is available for the purpose.

In order that the general relation of parts may readily he understood I have indicated in Figure v1 the'main water supply pipe 1 receiving water at normal pressure from the street main for supplying the water sys tem of the house. A trap 2 and usual control valves 3 and 4 are interposed in the main pipe and the supply pipe 5 for the house rises from the main pipe and passing'r through the cooler indicated as a whole by thenumeral 6, the water flows through the outlet pipe 7 from the cooler to a faucet pipe 8 from which water may be drawn off for domestic purposes through the faucet 9. Another branch pipe 10 is indcated as connected with the lower pipe 11 andthis pipe has a valve 12 for connection therewith of the hose for sprinkling the lawn or other uses exterior yof the house.

In addition td these two specified uses the water supply is drawn off through other outlets from the water system in the house, and as all the water of the house system passes through the cooler, it will be apparent that the supply in the cooler is intermittently changed and relatively cool water passing through the cooler will withdraw' the heat therefrom..

The( interior of the cooler or cabinet 6 is provided with a plurality of casings, three of which are indicated as 13, 14, and 15. These casings are of similar construction, cast as box-like structures from metal, with wide areas or surfaces for transmission of heat from the atmosphere within the cabinet to the interior of the casing. The cas ings are flat, closed bodies and are spaced in the cabinet to form supporting shelvesI for the food or provisions` or if desired sup` porting trays may be placed on the casings for the contents of the cabinet.

The lower casing is supplied with water from the inlet pipe 5, and after passing upwardly through the casing 13 the water flows through vertical pipe 16 to the intermediate casing 14, thence through the vertical connecting pipe 17 to the upper casing 15, and through pipe 7 to the water system of the house. y

Each of the casings is fashioned with an inlet port 18 in its bottom and an outlet port 19 in its top wall for connection therewith or' the inlet and outlet pipes of the casing.

The water is caused to flow upwardly through the series of casings, in a tortuous passage, for more eect-ively withdrawing heat from the entire upper and lower walls of the casings, by the use of a. pair of longitudinally extending, Vertical partitions 2O and 2l7 which form communicating chambers 22, 23, and 24 within the casing. The longitudinally extending vertical partitions connect the upper and lower walls ot the flat casings, but at one end each partition terminates near an opposite end wall of the casing, thus affording communication between the compartments as indicated by the arrows in Figure et, and as seen by dotted lines in Figure 2.

In the enlarged sectional View of Figure 3 it will be seen that the bottom ot' the inlet chamber or compartment 22 is at a lower level than the bottom of the intermediate chamber 23, and the bottom of the latter chamber is at a lower level than the bottom of the outlet chamber 24. This variation in the levels of the bottoms of compartments or chambers is carried out in all of the casings, and the entire bottom area in the interior of the casing gradually declines from the outlet compartment to the inlet compartment. Thus the water under pressure is caused to flow upwardly through the interior of the cabinet for cooling or refrigerating purposes. It it is desired to drain the cooler, it may be cut oil if desired from the water pipes of the house by closing a suitably located valve, then the valve 3 is closed, and valve 4t remaining open will permit water to be discharged through the trap 2. Under these conditions the water in the cabinet will readily drain over t-he declining bottoms of the plurality of casings to `the pipe 5 for emptying the cooler.

while I have illustrated three casings, it will be understood that these casings are interchangeable, and that a larger or smaller number may be utilized to increase or diminish the capacity of the cooler. The cooler or cabinet of course encloses the casings, and the cabinet may be insulated in suitable manner against the transmission of heat through its walls. The size of the casings may be varied, and deviations may be made from the preferred rectangular shape as shown, if desired or required, and it will also be apparent that the number of partitions within the casings may be varied, without departing from the spirit of my invention as set forth in the following claim.

Having thus fully set forth my invention, what I claim as new and desire to secure by Letters Patent is- The combination with an enclosing cabinet, of a series of superposed spaced casings having connecting' pipes, an inlet and an outlet pipe, means within each of said casings 'forming communicating compartments and a. tortuous passage and the bottom levels of said compartments desclining toward the inlet pipe.

In testimony whereof I aiiX my signature.
