Iceless Cooker and Refrigerator 



DEPENDING upon the heat of the 

 sun to retluce the temperature 

 within a cooler or refrigerator may seem 

 anomalous, but it has been proven 

 scientifically to be possible. The warm 

 summer days bring into prominence 

 the important question of preserving 

 food and keeping on hand a supply of 

 cool water. This is an easy matter 

 where ice and the receptacles for holding 

 it are available; but it is very desirable 

 to provide a means whereby a safe and 

 positive method of cooling can be 

 depended 

 upon, with- 

 out relying 

 too much on 

 the care 

 which must 

 be given to 

 the use of ice. 

 The illustra- 

 tion shows 

 the applica- 

 tion of the 

 principle to a 

 water cooler.

The cooler 

 may be made of heavy tin, galvanized 

 iron, glass, or stoneware. For con- 

 \enience the construction is of gal- 

 vanized iron. It is exceedingly simple 

 in design, and comprises a pan sixteen 

 ins. in diameter and four ins. deep. 

 Secured to this pan centrally is a 

 receptacle ten ins. in diameter, and 

 eighteen ins. high. The receptacle and 

 I)an are secured to each other by means 

 of an L-shaped |)ipe, the short end of 

 which passes through the bottom of 

 each. With a washer between the two 

 bottoms, the pipe is well soldered so as 

 to make water tight joints. 



The pipe extends out horizontally 

 below the pan, and is provided with a 

 faucet at its projecting end. A second

vessel twelve ins. in diameter with a 

 depth of twenty ins. is inverted over 

 the inner vessel, thus providing an 

 annular air space of one in. anjund 

 the vessel designed to hold the 

 drinking water. The outer shell has 

 a handle so that it may be readily 

 removed .

 and the inner 

 one, sixteen 

 ins. Both are 

 the same 

 length, and

 height, join- 

 ed together 

 permanently 

 at their up- 

 per ends by 

 means of a 

 rim. These 

 two parts are

 with legs and 

 the inner 

 shell has a 

 bottom one 

 inch above 

 the pan base. 

 It will thus 

 be seen that water placed in the pan will 

 flow into the space between the two 

 shells, and also beneath the bottom. A 

 top witii a handle and a sub-base so as to 

 provide an air space between, is adapted 

 to fit snugl\' within the inner shell. One 

 or more half-shelves may be placed 

 w iiliin the inner shell. 



In the cooler, water is also placed in 

 the pan entirely separate from the 

 drinking water which is in the shell. 



The cooling principle ma>- be stated 

 as follows: Tlie temiu-raturo of rarefied 

 air is cooler than air at normal pressure. 

 Condensation also plays an important 

 part in the cooling process. The moment 

 any water is drawn from the ctioler shell
