J y 1952 o. A. SUTTON FAN FOR HUMIDIFYING, DEODORIZING OR THE LIKE Filed Nov. 19, 1949 Y J 7 INVENTOR. 'Ofzja A. Sutfon pm'wm Patented July 15, 1952 v i "For: IIIUMIDIFYINQDEODORIZING, "ORTHELIKE 1: tutti-sum, Wichita, Kanssassignor td-The V Ont-Sutton Corporation, Inc.',;Wichita, Karts" I a corporation of Kansas Application November19,'1949, $erial No."1 2 8, 399" 5 claims. (on. 26 1-4091) My present invention relates to a unit for cir- I culating and treating air for human comfort or'" other purposes." The present invention comprises an air propeller mounted coaxially within an annular cowl within which liquid may be contained,

the-cowl comprising at least one large section of porous material'through which liquid may escape by:capillary action and from which the liquid mayjevaporate intothe stream of air being moved through the cowl. The. principal purpose of the present invention is'to providefor air circula tion and for treatment of. the air being circulated by constantly evaporating thereinto a liquid having desired properties. One purpose of the present invention is to humidity air which is drier than that required for human comfort.

Another purpose of-the present invention is to provide means for adding to the air in an enclosure a volatile substance having the property of-masking or. destroying cooking odors, cigar.

smoke and other obnoxious odors which may exist in aroom.

A further object of the present invention is to provide means for evaporating a disinfectant into a room in, order to sterilize the air of the room ,or' to sterilize portions of the rooms A further object of the present invention is to provide, in a unit having desirable aerofoil characteris'tics and incorporating the principles of the patent to Odor et al., No. 2.330.907, issued October 5, 1943, means for adding volatile liquid components of any;desired characteristic to the air ib gf irculated.
