A BEAK NOZZLE TESTED.
A new beak nozzle has been affixed to the water tower of the Rochester, N. Y., fire department. It is the invention of M. H. Hart, and is manufactured by the Fabric Fire Hose company, of New York city. It is made of metal entirely and is fitted with all the improvements. It can be raised or lowered by a cable, which could not be done with the old nozzle, as that was raised with the water pressure. The Hart nozzle Siameses the streams from the tower and concentrates their forces. The test took place at Front street and Central avenue, where sixinch mains are laid and the pressure is fifty-eight pounds. Four lines of hose were laid, two from a Holly hydrant 150 feet away, and two from another hydrant 300 feet away. A stream from a Hemlock hydrant was also coupled on to the tower. The test was first made with the Hemlock pressure alone, and then the full power of the engines was turned on. When a two-inch nozzle on the beak was used, with the tower extended, a solid stream was thrown a distance of 260 feet, in spite of the strong wind prevailing at the time. If there had been no wind, the stream would have been effective at 300 feet. A stream was also thrown vertically to a great height. The test showed that, with the new nozzle, although but two engines were used on the tower, the stream was thrown fully 100 feet farther than when the public test was made on Court street bridge, although three engines were used at that time. Chief Little recommends the purchase of the nozzle, which costs $250.
