Also, that mixing inside and outside air only makes mattersworse, as it gives the equivalent of a still warmer and moremoist outside air. And finalh^ it is obvious that the principle of utilizing theevaporative power of the air to cool, but discontinuing thesaturation of the air delivered to the room when the insideair has reached the critical point, is the correct principle,—theone covered by the Cramer patents. 1417 STUART W. CRAMER Cramer Air Conditioner. Individual (Belt Driven.) (Electric Driven.) These heads represent the only material advance made inthe_ individual type of humidifier in many years. Prior totheir advent upon the market, galvanized iron or any suchmaterial was good enough for humidifier work; the perma-nence of our seamless drawn copper sheet metal work, how-ever, has caused others to copy. This is even more true of itswell known feature of accessibility for cleaning, for nowevery one makes some pretense to that feature. Our first headsof this type had split, or sectional, casings; but that con-struction was discarded because of their so quickly workingloose and out of shape; as soon as we hit upon the presentconstruction, _we threw out and replaced the old unsatisfac-tory split casings in such mills as we had installed them. The fans on these heads practically double their humidifiercapacity, and increase their air cleansing capacity six to eighttimes! One remarkable feature pecu
