The Street railway journal . towers which have beenproven in operation to be of insufficient capacity or wheretower construction is not permissible and it is necessary toinstall the system in ill-adapted spaces. Owing to the spacesbetween trays the efficiency of this type of construction inoperation is claimed to be greater than that of the otherforms of construction, and it is also claimed that greateruniformity of results in cooling between towers of thelarger and smaller capacities will be secured. The spray-preventer construction involves the use of gal-vanized iron baffle plates or enclosures, which are hung out-side of the tower at each stage and on such sides as tocatch the spray carried outside by strong prevailing baffles are hung some distance out from the tower so asnot to interfere with the wind currents of ordinary in-tensity, and are inclined inward toward the bottom whichis flanged into a gutter to collect the water and deliver itback to the tower again. These baffles, or spray catchers,. TRAYS SUPPORTED BY STRUCTURAL IRON FRAMING are hung alongside of the upper portions of the stages, therebeing a fine mesh screen enclosure around each group oftrays lower down. These spray catchers are ordinarilymounted on the lee side of the tower so as to be effective incatching the spray from all prevailing winds. These improvements in tower construction were designedand patented by B. Franklin Hart, Jr., who has an extendedexperience in cooling tower practice. The tower is intendedfor the cooling of water and liquids for any purpose, and iseffective without the use of fans or moving machinery.
