A Fire Curtain Of Water

An eftective device for the protection ef buildings from fires in adjacent Itructures has been successfully tested in Boston. The idea worked out in the apparatus is to maintain a sheet of water between the fire and the building to be protected. This is done by placing on every open side of the building near the top a line of perforated piping for carrying the water. The complete apparatus consits of a five-inch standpipe, extending over the upper story. Krom it runs another pipe around the sides and front, from two and one-half to four inches in diameter. On the front are three revolving sprinklers, and one is placed at each exposed side, in the center. The arms are of bronze metal, slightly curved. At each end of the arms is a ball nozzle, such as is used by flre departments on regular hose lines. At the Boston test a fire department steamer furnished the power, and for about fifteen minutes poured through the sprinkler a delivery of 1,000 gallons a minute, completely drenching the walls, and keeping a continuous sheet of water from top tt bottom.
