17,755. Hart, J. A. Aug. 17. Air, moistening, heating, cooling, filtering, &c.-Relates to apparatus such as that described in Specification No. 20,358, A.D. 1900, for use in ventilating workshops &c. with filtered, cooled, or warmed and moistened air, and consists in arranging the coir, coco-nut matting, or other moistened material in folds, depending loops, or a series of sheets, so supported as to constitute passages d, e, preferably widest at their open ends, for the incoming and outgoing air. The material A, Fig. 1, is arranged in loops, and is supported between the troughs B, C by vertical rods a. It is supplied with water from the upper troughs by its ends a2 being hooked into the trough, or by means of a wick. In the casing G, Fig. 5, the material in one length passes through troughs B, into which it is depressed by hollow rods h or solid bars i. Water is supplied under pressure from taps on the pipe b. Fig. 5 also illustrates guide-plates a3 to prevent the air from passing anywhere except through the moistened coir or matting, and wheels l on which the apparatus can be run in and out of the casing. The loops may be arranged lengthwise or widthwise of the casing, horizontally or vertically, and some or all of the ends of the loops may be at different levels, as shown in Fig. 9. Fig. 11 illus. trates the use of a trough B' to provide water, with a narrow opening b2 and deflectors b3 to spread the water. In this case, the material A is supported on solid bars i' and the trough may be divided longitudinally into compartments. The supports may consist of perforated rods with a deflector, and extra cross-rods may be used as supports. The moisture can be conveyed to the coir &c. by the air, or by spraying, and the water running off the material is passed away through perforated troughs C. Coils K, as described in the prior Specification, may be used for attemperating the entering air.
