A UNITED STATES PATENT OFFICE.

ISAAC FISI-IER, OF NEIV YORK, N. Y.

NOZZLE.

SPECIFICATION forming part of Letters Patent No. 440,025, dated November 4, 1890.

Application filed March 27, 1890. Serial No. 345,579. (No model.)

To all whom it may concern: i

Be it known that I, ISAAC FISHER, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Nozzles, of which the following is a speciiication.

This invention relates to certain improvements in nozzles which are intended particularly for fire-hose, the nature of such improvement being pointed out in the following speciiication and claims, and illustrated in the accompanying drawings, in which- Figure 1 represents a longitudinal central section when the valve is open. Fig. 2 is a similar section 'when the valve is closed. Fig. 3 is a transverse section in the plane w w, Fig. 1. Fig. 4 is a similar section in the plane oo oo, Fig. 1. Fig. 5 Vis a similar section in the plane y ly, Fig. 1. Fig. 6 is a section in the plane .e e', Fig. 2.

In the drawings, the letter A designates the shell of the main nozzle, which is provided with a supply-opening a and with a discharge- Opening b, the former being provided with an internal screw-thread to make connection with the hose and the latter with an external screw-thread to make connection with the mouth-piece. The shell A is provided with a lateral tubular extension B, which is located at one side of the shell, between the supply and discharge passages a b, and freely communicates with the supply-opening a of the Shell A.

C is a Valve, which in the example shown in the drawings is made in the form of an india-rubber ball, and is opened and closed by means of a screw-cap D, as fully described in Patent No. 414,509, granted to me November 5, 1889.

The tubular extension B is closed by a screw-cap E, and on the body of the said extension is formed a circular seat c, on which is fitted a rotating ring F, from which extend one or more secondary nozzles G G G2, three being shown in the drawings, which are graduated, the nozzle G having the smallest and the nozzle G2 the largest bore. The seat o is made slightly tapering toward the mouth of the extension 13,50 that the ring F can be ground thereon and that a water-tight joint can be produced. The secondary nozzles exa line parallel with the'main discharge-nozzle` to throw the stream to a greater distance and in a path which is parallel with a right linefrom the main nozzle to the point where the stream is to be thrown. In this respect my invention diers from a nozzle having a ring rotating in a plane at right angles to the longitudinal center or axis of the main nozzle, and having aseries of tubular passages which diverge toward the discharge of the nozzle to simultaneously deliver a series of diverging streams. The screw-cap E serves to retain the ring F on the seat, and in the seat is an opening ol, so that by turning the ring F either one ot' the nozzles G G G2 can be brought in communication with the interior of the tubular extension B. It will be readily seen that the bores of the secondary nozzles are much smaller than the bore of the main nozzle, and if it is desirable that a stream of water shall be thrown to a distant point which cannot be reached by the main nozzle the valve C is closed, (see Fig. 2,) and the water supplied to the shell A is caused to discharge through one of the secondary nozzles. In certain contingencies it is also desirable to reduce the quantity of water which discharges through the main nozzle, and in such cases a portion of the water supplied to the shell A is permitted to discharge through one of the secondary nozles, the valve C being left open, as shown in On the shell A is formed an annular spraychamber H, which communicates with the supply-opening a of the shell through openings h h, Figs. 4 and 5. On the outer surface of the spray-chamber H is cut a screwthread to engage the spray-nozzle I. Between the inner surface of this spray-nozzle and the outer surface of the shell A is left a narrow annular space o', which terminates beneath a iiaring flange j, so that the water forced out through said annular space is diverged outwardly in all directions, and the iiremen who manipulate the nozzle or are engaged in proximity to it are to some extent protected against smoke and heat. When the spray-nozzle I is raised to the position shown in Fig. l, the spray-chamber communicates through an annular opening le, Fig. 3, With the annular space i; but if the spray-nozzle is depressed to the position shown in Fig. 2 the annular opening k is closed by means of a packingring l, secured on an internal shoulder of the spray-nozzle. It will be readily seen from the foregoing description that my spray-nozzle I can be raised more or less, and that the quantity of Water discharged from the same can be regulated as circumstances may re'- quire. At the same time the spray-nozzle I is placed in such a position that the man Who handles the main nozzle can readily adjust the spray-nozzle t0 suit himself and the men employed in his proximity, so that no time is 10st in case of a sudden emergency.

What I claim as new, and desire to secure by Letters Patent, is

l. In a hose-nozzle, the combination of the main-nozzle shell having a supply and a discharge passage and at one side a lateral tubular extension provided at its front with a port or opening7 a valve for controlling the flow of the tiuid through the discharge-passage, and a ring arranged on the lateral extension, rotating in a plane parallel to the longitudinal center or axis of the dischargepassage, and having a secondary nozzle which moves With the ring in the plane parallel to said center or axis to communicate with the port or opening and increase the distance to which the stream is thrown, substantially as described.

2. In a hose-nozzle, the combination of a shell having a supply and a discharge passage and at one side a lateral tubular extension provided at its front side with a delivery port or opening, a valve for controlling the flow of the fluid through the dischargepassage, and a Vring rotating on the tubular extension in a plane parallel with the discharge-passage of the main-nozzle shell and carrying a series of secondary nozzles of different-sized bores, and any one of'which secondary nozzles can be brought into communication With the said delivery-port, While the other secondary nozzles are cut off from communication with the interior of the shell, substantially as described. p

3. In a hose-nozzle, the combination, with the nozzle-shell having discharge and supply passages and a spray-chamber around the discharge-passage and in communication With the supply-passage, of a valve for stopping the iioW of fluid to the discharge-passage Without stopping the flow to the spray-chamber, an adjustable spray-nozzle on the shell, and a iiange overlying-or overhanging the delivery-mouth of the spray-nozzle, substantially as described.

4. In a hose-nozzle, the combination, with the main-nozzle shell having supply and dis- Witnesses.
