I. NOZZLES AND PLAY-PIPES.—Figs. 5 and 6 represent a novel form of flexible play-pipe made of rubber-lined cotton, wound on the outside with brass spring-wire. At A is shown a simple form of nozzle, which is opened or closed by the movement of the swinging pail, as indicated by the dotted lines, Fig. 7 shows— The Maw Controliing and Slod-olT Nozzle (in by means of which a stream can be reduced to any size or shut off at will. A conical plug, operated by an exterior hand wheel, is inserted more or less into the throat of the pipe.
The Clemens Controlling and Spray-Nozzle (Fig, 8) is somewhat similarly constructed, the conical ping being moved into and out of the constricted throat by means of an exterior nut.
7'he Oyslon Spray-Nozzle (Fig. 9) enables the pipe-men to approach and enter a burning building, and with it the excessive use of water and unnecessary damage to goods may be avoided. it consists substantially of a common nozzle having a number of small levers pivoted around it near the outer end. These levers extend about', in. beyond 1 he end of the nozzle, and are inclosed in a neat cup or guard, completely protecting them from injury. The ends of these levers are connected with a collar in such a manner that, when the collar is revolved one eighth of a revolution to the right, tlic wedge-shaped parts of half the levers are projected into the stream, dividing it lip into a number of triangular ley turning the collar in. farther, the remaining four levers arc projected into the stream, dividing it up the number of streams. These streams, after leaving the nozzle a few feet, be as den., maws of flying spray.
Spray-nozzles are exeeedingly effective in lighting smoky fires. the spray driving the smoke from in front of the fireman, and also keeping up a current of cool air, while the solid stream directed from the same nuzzle is projected into the bunting mass. The circular sheet of spray may he from 89 to 100 ft, in diameter. In Figs. 10 and 1I is represented Phe PPanly Combination Nozzle.—This is provided with an adjustable ring, which, en circling the spray openings, direets the sheet of spray either forward, as shown in Fig. ill, or
backward, as in Fig. I1, the solid stream being sh»tiltanemiKly projected from the nozzle proper.
The _Monitor _Nozzle, manufactured by Messrs. A. J. Morse & Son, of Boston, Mass. (Fig. 12), is intended to be at tached to stand-pipes, hydrants, or at any place where there is a water-supply, and whence it is desired to have an effective stream instantly available in case of emergency. It consists of a chamber which rotates upon its base, provided with a hose-pipe, which pipe, by means of a hand-lever, may be elevated or depressed at any angle. The nozzle has practically. therefore, a universal motion, which allows it to be directed to any point. The change of direction can be made with very little ex ertion, even with a 2-in, stream operated under 123 lbs. pressure or more, and car rying about 1,000 gals. of water per min. One man can easily control it, and not the least of its advantages is that, when a building is provided with several such nozzles, a single watchman can start an effective stream upon a fire, leave it in full operation while he hastens to the next nozzle and starts another stream, so that even before an alarm is given the work of one man may be of the greatest value.
The Perfection Bolder and Nozzle (Fig. 13), manufactured by Messrs. Samuel East man & Co., of East Concord. N. II., is an effective device for handling fire-streams without the use of discharge-pipes. By its aid one person may direct two, three, or four nozzles all at the same time from different lines of hose with over 100 lbs. water-pressure at each nozzle. It consists of a holder for the hose-section and a short nozzle easily attached thereto. The device is held by the user, as shown in the figure.
In the hale vacuum-nozzle, represented in Fig. 14, the air enters through side openings A. producing a contracted stream which it is claimed can be pro jected over unusually great dis tances.
