    rt N'° 21,012.—A.D. 1903. Construction of Apparatus for littering, &c., Air to be Supplied to buildings. tion and in what manner the same is to be performed to be particularly described and ascertained in and by the following statement : — The object of this invention is to construct an apparatus for efficiently filter¬ ing or humidifying air to be supplied to buildings. nor the purpose ot my invention 1 construct tne apparatus of two or more 3 tubular bouies or frames arranged concentrically or otnerwise, such bodies or frames being covered with cocoa fibre or other labric, or woven, knitted, per¬ forated, or oilier material. These tubular bodies are supported by bearings and one or more or all are capable of rotation in the same or opposite directions and at the same or different speeds, and such tubular bodies are situate in a 1 ■) trough or troughs which may contain water or a disinfecting liquid. (Jne end of each tubular body is closed either by the material with which it is covered or by a different material, and when the tubular bodies are arranged concentrically, the other end between the edge of the outer tube or tubes and the edge of the inner or next tube is closed also, the centre tube only being 15 open at one end and this open end is in connection with a fan or other suction or blowing appliance which sucks or forces the air through the fabric surround¬ ing all the tubular bodies and so purities disinfects, humidfies, or otherwise treats the air before being passed to a building. When a liquid is in the trough the tubular bodies are always kept wet so that the air will become ?0 humidified or disinfected according to the material placed in the trough, and by reason of the end of the outer tubes being closed all the air must pass through the fabric surrounding the tubes and so becomes thoroughly treated. The annexed drawings indicate one example of carrying my invention into effect. 2d 40 Figure 1 is a longitudinal section of the apparatus. Figure 2 view of the drums at their open ends. Figure 8 a section of the drums and trough. According to this construction two drums 1, 2 are employed, one 2 being within the other. .10 Each drum is made of a skeleton character from metal or wood rings 3 and bars 4 and these are connected to their axle 5 or bearings 6 by spokes or plates 7, the outer surface of each drum being covered with a medium 8, such as opened meshed cocoa nut fibre, through which air can be sucked or forced. The inner drum 2 is provided with an axle 5 which rides in bearings 9 of ‘16 standards 10 secured to a floor or other place and such axle carries the bearings (i of the outer drum 1 so that both can be revolved in the same or opposite direc¬ tions according to the arrangement of the driving gear. The axle 5 carries at one end a gear wheel 11 and the bearing 6 of the drum 1 at that end carries also a gear wheel 12. The gear wheel 12 is in mesh with a pinion 18 secured to an axle 14 on which is arranged a pulley wheel 15 so that said outer drum 1 can be revolved, while the gear wheel 11 is in mesh with a pinion 16 carried by a sleeve 17 which also has a pulley wheel 18 so that the drum 2 can be revolved, and by revolving the pullies in the same direction the drums will be moved in the same direction, 45 or by revolving only one pulley, one drum will remain stationary, or by revolving the pullies in opposite directions, as indicated by the arrows, the drums will be revolved correspondingly. The drums are arranged over a trough 19 which may contain a disinfecting or other liquid so that as the drums revolve the surfaces 8 are kept constantly 50 wet, and the drum 1 has flange rings 20 which meet the edges of the drum 2 so as to close the ends of the drum 1, and one end of the drum 2 is closed whilst the other or open end is situate next an opening in a wall 21 or casing so that all air which is drawn or forced through the drums 1, 2 by a fan or otherwise must actually pass through both drums, and by revolving the drums 55
