Can Have His Own Cold Air Machin

Can Have His Own Cold Air Machine.
 Washington Letter.
 My invention will relieve the suffer- ings of distressed humanity in the sum mer time." said Prof. Willis l.. Moore. as he showed to your correspondent an odd-looking cylindrical tank which stood in one corner of a great room at the United States Weather Bureau. Hence forward nobody who is sufficiently well- to-do to burn coal for warmth in winter need suffer from heat in the torrid sea- son. My machine can be run for about the same cost as a stove, and, according to the size selected, will cool a room, a flat or a dwelling" se.
 was so chilly as to be rather uncomfort- able, though the temperature outdoors
 was S5 degrees in the shade. thermom- eter, which hung from the ceiling in the temperature was exactly GA degrees. Out of a pipe at the bottom of the apparatus
 rushed a stream of air at 36 degrees Fah-
 renheit Gas indicated by another ther- mometer). the force of it's current turn
 ing little wheel which was part of an
 air meter. showing the velocity of the
 stream.
 The stream of air comes in from out
 side at temperature of S5 degrees. ex-
 plained Professor Moore, ''and, descend
 ing through the cylinder, emerges pres
 ently at 36 degrees. In the upper part of
 the apparatus 1t is cleaned and dried. in-
 cidentally to partial cooling. and in
 the lower section 1t is reduced almost to
 freezing point. The advantages of redIc-
 ing the humidity is obvious, while the cleaning of the air. so as to free It of
 dust and dirt. renders 1t more healthful to breathe. As 1t comes out at the bot
 tom of the machine at the rate of 125 cubic feet a minute, it spreads along the floor
 of the room and slowly ascends, forcing
 the warmer air out through the open top of that window over there, and thus se- curing an admirabla ventilation.
 The machine uoes not require any
 power to keep 1t going. It is absolutely
 automatic, It's working being caused by the difference in specific gravity between the warm air outside and the cool air inside. The warmer the air outdoors be- comes, the faster the apparatus works. Thus. when 1t is 100 degrees in the shade outdoors. the cooled air pours out in the room at a great rate, whereas, on the other hand. if the thermometer goes down to 65 degrees. the contrivance stops working of its own accord. The hotter it is the faster it works, and vice versa, the machine regulating itself. and always supplying just the requisite amount of cool air.
 "The machine requires no attention ex-
 cept to be charged once day With cer-
 tain composition, just as you would put fuel into a furnace. I am not prepared
 just yet to disclose the nature of the composition, but the formula will be made public as soon as my invention has been fully protected by patent. The cooling
 stoves. if such they may be called, will
 be made of various sizes. One six feet in height will suffice to keep large room at the proper temperature during the hottest weather. The one you see before you. which is twelve feet high, would serve to cool a hospital ward.
 Not only private dwellings, but office buildings will doubtless be cooled by these machines before long. They will be specially serviceable in hospitals, where hitherto the difficulty of keeping down | the temperature in summer has always been cause of much mortality among | the sick. Inasmuch as they will clean the air and free 1t from microbes. while cool | ing 1t, additional benefit will be derived | from their use under such conditions Perhaps I should have explained that | the stream of cool air may be turned of at any moment by simply pressing knob which controls a damper. shutting off the
 current of warm air entering above from | outdoors.
 "You will notice that the outside of the machine down below is incrusted with about an eighth of an inch Of fine snow | and that there are also a few icicles hanging to the galvanized iron of the | cylinder. Of course, both snow and ici- | cies are formed by the condensation oi
 water from the air of the foom.'
