1,251,655. Cooling towers. BLAIRS Ltd. 21 Nov., 1969 [23 Aug., 1968], No. 40484/68. Heading F4K. A cooling tower has its weight supported by a main frame structure comprising vertical steel members 11 interconnected by means of horizontal steel members 15. The tower packing material, water distributing nozzles and a drift eliminator are suspended from trusses 16 extending diagonally across the top of the main frame structure. The trusses also carry a framework 17 for supporting a fan unit (not shown). Preferably the framework 17 includes a cantilever member (19, Fig. 3) to transfer some of the weight to outside the main frame structure. Glass-reinforced plastics panels 27, 28 forming an external casing are secured to framework 18 which in turn is carried by the vertical members 11. The top of the tower has plastics panels 22, 23. A water receiving pond 13 is located below the tower. The frame members 11 pass through collars 12 in the bottom of the pond into the ground at 14 so that their weight is supported independently of the pond structure.
