Two members of the New York Fire Department, located in the Borough of Richmond (Staten Island), Frederick Balzer and Conrad Schwall, have devised a very effective nozzle for extinguishing chimney fires. The tip of the nozzle is provided by an ordinary brass lawn spraying nozzle. This nozzle may be regulated to provide a stream spray to ⅜inch stream. The spray is employed for extinguishing chimney fires, while the ⅜-inch stream it can deliver is used for washing down any sparks which may have fallen on shingle roofs. The following fittings are employed to make up the nozzle, using the lawn spray nozzle as tip:

One and one-half x 3/4-inch double female coupling; 11/2inch female to fit standard hose; ¾-inch female pipe thread. Inserted in the ¾-inch female thread is a 3/4 x ¾-inch male nipple, which in turn is provided with a 3/4-inch pipe thread on one end and a ¾-inch male hose thread on the other.
