A Fire Curtain Of Water

An effechve device for the protection of buildings from fires in adjacent structnres has been successfully tested in Boston. The idea worked out in the apparatus is to maintain a sheet of water between the lire 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 water. The complete apparatus consists of a flve inch staudpipe, extending over the upper story. From it runs another pipe around the sides and front, f rom 2% to 4 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 fire departments on regular hose lines. At the base of the standpipe is a Siamese connection for four lines of three inch hose. At the Boston test a fire department steamer furnished the power, and for. about 15 minutes poured through the sprinkler a delivery of 1,000 gallons a minute, completely drenching the walls and keoping a continuöus sheet of water from toD to bot.
