l Application filed December 13, 1899. `Serial No. 740,157. (No modell) To a/ZZ whom t may concern:

Beit known that I, THoMAs HALEY, of Bos;l

ton, in the county of Suffolk and'State of Mas'A sachusetts, have invented ,certain new. and

useful Improvements in Controlling-Nozzles, of which the following is a specification.

This invention has for its object to provide a hose-nozzle for fire-engines, &c., adapted to increase or decrease the size of the stream while playing and to entirely shut od the stream. A j

\ The invention consists in the improvements which I will now proceed to describe and claim. i', Of the accompanyingdrawings, forming a part of this specification, Figurelrepresents a side elevation of myimproved hose-nozzle. Fig. 2 represents a longitudinal section of the same, showing the nozzle adjusted to give a stream of maximum diameter. 4 Fig'. 3 represents a section on line 3 3 of Fig. 2; Fig. 4 represents a side view of the adjustable' inner member of the'nozzle. Fig. 5 represents a View similar to a portion of Fig..2, showing the inner member adjusted to entirely shut off the stream.

The same reference characters indicate the same parts inail the gures.

My improved hose nozzle comprises an outer or guiding member, which, as here shown, is composed of two sections 2 and 3 of different diameters, the section 2 being of greater diameter than the section 3. The section 2 has at one end an internal thread 4 for engagement with a suitably-threaded terminal on'ahose and is internally threaded at its opposite end to engage a threaded -iange 5, formed on the section 3. The section 3 is externally threaded at its outer end to receive a stop-collar 7, which cooperates with the flange 5 in confining on the section 3 the rotary adjustingnut 8, hereinafter referred to. Between the flange 5 and stop-collar 7 longitudinal slots 6 6 are formed in the section 3 fora purpose hereinafter described. j The nozzle also comprises a movable inner member 9, which is iitted to slide in the section 3 and has a flaring end 10 projecting into the section 2 and having a sliding fit therein, said movable member 9 constituting the delivering end of the nozzle.

12 represents a cone which is supported by thin blades or wingsY 13, affixed tdthe cone :and to the section 2, the cone being supported lin a position concentricwith the members of the nozzle and having an elongated apex projecting into the movable member 9, there being an annular space between the base of the cone and the interior of the section 2. base of the cone and the iiaringend of the movable member 9 are so proportioned that when the member 9 is in the position shown in Fig.' 5 its fiaringend constitutes a valve,

which is seated on the face of thecone,1the

latter constituting a'valveeseat, so thatthe 4; iiow of water through the nozzle is cut oif.

AMeans are provided for adjusting the mov- Vab le:member 9 longitudinally toward and from the base of the cone, 4said means comprising` an eXternallyLthreaded collar. 14, surrounding'the section 3 and engaged with internal threads formed in the sleeve 8, the latter constituting an elongated nut, which is rotatable on the section 3 and is confinedagainst endwise movement thereon by the flange 5 and the stop-collar 7. The externally-thread. ed ring 14 is rigidly connected with the movable member 9 by means of studs 15 15, which pass throughthe slots 6 6 in the section Sand are guided 4by said slots, the member 9 and threaded ring 14 being thus prevented from rotating whenthe sleeve or nut 8 is rotated.

It will be seen from the foregoing that the rotationof the sleeve S causes an end wise movement of the movable member 9, thus varying the position of the iiaring end 10 of said member relatively to the face of the cone. The inner surface of the Haring end 10 and the external surface of the cone form an an- Vnular space or passage which converges toward the apex of the cone and is varied in Width by adjustments of the member 9. When the member 9 is adjusted as shown in Fig. 2, a stream is formed which fills the interior of the movable member 9. Any adj ustment of the movable member toward the base of the cone decreases the size of the stream, the stream being caused by the elongated apex of the cone to separate from the inner surface of the member 9 when the said member is adjusted from the position shown in Fig. 2 toward the base of the cone, so that the stream Iiows in a solid form fromthe apex The IOS

of the cone without touching the inner surL Y `the cone 12.

face of the member 9, :the size ofV vthe streamA decreasing as y"the member 9 is adjusted `to ward the base of the cone. I am therefore enabled to produce a stream of any diameter from the internal diameter of the delivering end of the member Sito-an extremely-small stream-#say one-fourth of an inch in diameter.

16 represents a water-spreading cone Whichis attached to the base of the cone 12 and projects toward the receiving end of the nozzle,

said cone being formedY to guide thestream-A outwardly with an easy curve tothe b ase of The dividing-cone 16 is preferably somewhat concave in its longitudinal section, as yshown in Fig. 2.
