NOZZLE FOR HOSE AND DISCHARGE PIPES.

SPECIFICATION forming part of Letters Patent No. 302,542, dated July 29, 1884.

Application iled October 22, 1883. (No model.)

To all whom it may concern:

Be it known that I, MnLvILLE CLEMENs, a citizen of the United States, residing at N ew York city, in the county and State of New 5 York, have invented a new and useful Improvement in Nozzles for Hose and Discharge Pipes; and I do declare the followingspeciiication to be a full, clear, and exact description of my said invention.

io My said invention consists, chiefly, in the adaptation and arrangement, in a fluid-discharge nozzle, of a hollow disk or shell fitted upon the nozzle-barrel to revolve freely thereon, and provided with orifices or discharge- 15 ports in the disk or shell, so formed that when the nozzle is supplied with water or other iiuidv under pressure above the external pressure there will be discharged from the nozzle-ports streams directed in various lines and angles,

i 2o and also the disk be caused to revolve upon its axis, thus distributing the dischargingiiuid in various planes, so as to cover all space about the nozzle within its reach.

The invention also includes an arrangement 25 for a closing-valve or shut-off77 for the said distributing-nozzle; and the said invention further includes the combination,with the said distributing-nozzle, of a plain7 or single round-streamnozzle, provided with an indego pendent closing or shut-off valve from that of` the distributing-nozzle, so that in the combined arrangement either `the distributing-l '45 tributing-nozzle closed and the plain nozzle open, Fig. .3 being, in part, a longitudinal section, and Fig. 4 being a full top View.

Referring to the drawings, a nozzle-barrel,

A, with its head B fitted, as is commonly done,

5o to screw on the butt or end of a hose or discharge-pipe, has screwed on its outer end a cap, C. A hollow disk or shell, D, shaped like a iiattened sphere, is fitted to revolve freely on its axis, concentric to the axis of barrel A, with onejournal-bearing formed on the 5 5 screw-flange of cap C and another journalbearing of it upon a tubular or sleeve valve,

E, which fits freely and concentrically on barrel A. A iiange of cap C keeps diskD in position on barrel A. In the valve E is fixed a 6o stud-pin, F, fittedto slide freely in a groove,

G, formed longitudinallyinthe outside of barrel A.

Exterior to barrel A and valve@ is a ribknurled7 hand-sleeve, H, fitting freely on 65 barrel A, between anges of disk D and the head B of barrel A, and having an internal left-hand screw-thread formed in it to match and engage a like external screw thread formed on the sleeve-valve E, so that by turn- 7o ing the hand-sleeve H to the right the valve E may be closed by coming to its seat on the screw-flange of cap C, (see Fig. 3,) and by turning sleeve H to4 the left the valve E may be opened to the position shown in Fig. 1. 75

In the barrel A are formed transverse outlet-ports Q, Q Q Q, leading from the interior of barrel A to the interior space of disk D, when valve E is opened, so that by opening and closing` valve E the discharge-fluid is re- 8o spectively admitted to or shut off from disk D. rIhe disk D has six discharge-ports, a a', b b', and c c', formed through its shell or walls, the ports a c being central to the disk D in a plane at right angles to its axis of rotation, but made 8 5 with their axes inclined from radial lines from the center of disk D, in order that when iiuid (under pressure in disk D) is discharged out of them its reacting force shall canse the disk D to rotate slowly on its axis in the direction 9o of arrow d. As the disk D is balanced, when under fluid-pressure .within it, as to journalend forces, and as it is also nearly balanced on its axis as to lateral forces, it is evident `that it requires but very little reacting force 9 5 from the outlowingJ ets or streams of the ports a and a to rotate the disk on its axis, and there- 1 fore their inclination from radial lines to the center of disk D may be made slight and only enough to rotate the disk slowly, so as not to roo break up and scatter into spray the issuing iets or streams by too rapid rotary distribution, but to deliver them solidly and effectively in their respective discharge-planes.

At port a is shown in Fig. 2 a short bent tube iixed in the port. Its use gives greater rotative force to the jet of the port, but is therefore objectionable, because itfornis spray of the stream and acts to carrythe outi'lowing uid around oppositely to the direction of its natural outilow, and to thus reduce its eiiective velocity of outflow.

The ports b b lead i'rom opposite sides of the upper portion of disk D,at an angle of their axes ol' about forty-ve degrees from the axis of disk D, and they discharge forward as the disk revolves. The ports c o lead from opposite sides ofthe lower portion of disk D, inclined about forty-'live degrees to the axis of D, discharging backward toward the pipebutt as disk D revolves. Thus the ports a a serve to revolve disk D, and, together with ports b b and c c, serve to distribute the six jets or streams substantially in all directions from the nozzle in a most efficient manner for tire-extinguishing.

The cap C has formed concentrically on it a ball, I, through which is formed a plain nozzle, K, in line with barrel A. rlhis plain nozzle is provided with a closing or shutott' valve, L, which is a close-iitting shell on the ball I, pivoted in the transverse axis of the ball by a iiXed screw-pivot, M, and an adjustable screw-clamping pivot, N, in ball I. The valve L is moved by a knob, O, back and forth from its position shown in Figs. l and 2 to that of Figs. 3 and 4, where its movement is stopped by pin P in ball I.

In Figs. l and 2 the plain nozzle K is shown closed by its shut-oit' valve L, and the distributing nozzle or disk D is shown opened by its valve E, so that only the distributing-disk I) is discharging.

In Figs. 3 and 4t the distributing-disk D is shown closed by its shut-olf valve E, and the plain nozzle K is shown opened by its valve L, so that only the plain nozzle K is discharging. By opening the two valves E and L both the disk D and nozzle K will discharge, and by closing E and L there will be no discharge. The diagonal disk Dl may therefore be substituted with advantageous results for the flattened-sphere disk D.

I am aware that nozzles for hose and discharge pipes for nre-extinguishing and other purposes of fluid distribution have been made prior to my invention in which the discharging-nozzles were made to revolveupon their axes or nozzle-barrels; but I know of no hose or distributing nozzles having thedistinctive and effective features and principles of operation of my invention as set forth in my foregoing specification.

I claim as of my invention- The described hose-nozzle, consisting of the hollow disk D, having the discharge-ports a a I) b c c', and arranged to revolve upon the nozzle-barrel A and to be supplied with water through ports Q Q Q Q in the barrel A, and provided with a shut-off valve, E, operated by the hand-sleeve H, all constructed, combined, and operating together, and with the described plain nozzle K and its shut-off valve L in the cap C, all substantially as and for the purposes` set forth.

MELVILLE CLEMENS.
