This invention relates to'hose nozzles and` the like, and has for an object to provide ya nozzle of improved and simpliiied construction which is adapted to be quickly and easily adjusted for producing a relatively small stream or spray, or a comparatively large stream o`r spray substantially equal to the-full capacity of the conduit supplying the liquid. Another object is to provide an improved nozzle having' a plurality of valves, and acommon operating member for successively opening or clos-ing the respective valves. It consists in certain features and elements of construction herein shown and described, as indicated by the claims;

In the construction illustrated in the drawing, the nozzle tting includes a coupling member,- 10, which is interiorly threaded at one end for connection with the usual coupling member of a. hose or the threaded end of any suitable form of conduit. This coupling member is provided with a' reduced tubular extension 11, on the outer end of Which-an operating sleeve, 12, is threaded and arranged for lrotative axialmovementthereon, which movement controls two concentrically arranged valves located adjacent the outer end of said sleeve,- 'asy hereinafter described. Preferably cast integral with the interior of the extension, 11,- is a spider, 14, with which is rigidly associated a centrallyv disposed needle valve member, 135, which is herein shown as a separate element having itsrear end riveted over as indicated at 15a', in said spider.` As may be seen in Figure 1 of the drawing, this needle valve element extends lfor convenience,

lmember for the outer 1930;A serial No. 460,808.v

a substantially distance beyond the outer end of the tubular" extension, 11, and has its eX- treme end conicallyriorme'd as indicatedat 16, which serves as the valveproper.l Slidably mounted on the outer endof said needle valvemember is a part, 18, disposed wholly within theoperating sleeve, 12, and which, may be termed af duplex valveelement becauseV it Sielves as a seat for the inner valve and -is ineiiect the valve proper for the outer valve, as will hereinafter' be seen.`

j The duplexvalve element includes a sleeve, 19, which Vfits' snugly around and is axially movable on the needle valve'member, and` Wli'ch sleeve is provided with a pair of diametrically opposite longitudinally extending slots, through which extends a" cross pin, 21, projecting diametrically through the needle valve element. The pin and slots thus prevent rotation of saidv cduplex7 element on the, needle valve member and serve to define the limits of axial movement of said fduplex element relative' thereto. `Integrally formed withthe sleeve, p19, of the duplex element. is an annular portion, `22, the inner surface ot which, as indicated atp23`, serves as the seat for the conical valve, 16, which controls the inner valve port or orifice, 23a, in said dir plex element, while the exterior surface of said portion, 22, .is formed rusto-conically, as indicated at 24, and serves" as the valve or supplementary rt'ion, 22, and the duplex element are con` 8 ality of longitudinally' exwhich Vare radially offset relative to said needle valve member, 15, as seen in Figures 3 and 4', so as to insure passage of the liquid'therebetween for discharge through the central orifice, 23e,x in the annularporti-on, 22. Y l

To furtherfinsure true axial movement of thiSjFduplex element I form said element with a plurality of' radially extending fins, .95 26, Vwhichare* dimensioned to substantially engage the inner wall of the operating sleeve, Y 12, and preferably these fins v.arelocated in alignment withv4 the respective ribs, 25, so as to reduce the Obstruction to the flow of the p valve. The annular po sleeve,-19,y of the nected by a plur tending ribs-,25,

' element outer end of the operating sleeve, as may be clearly seen in Figure`4, and 1s arranged to abut and firmly lock the seat, 29, in position 'against said shoulder, `28, of the operating sleeve. The seat, 29, may be made of any suitable material such as metal, fibre, rubber,

etc. Preferably it is held against rotation with respect to said operating sleeve, and to so maintain said seat, it is formed with one or more laterally projecting lugs, 33, vwhich are adapted to register in correspondingly formed slots, 34, providedin thestop shoul-v der, 28. By virtue of this construction -it will be apparent that may be'quickly and readily replaced i'f-necessary when it becomes worn or mutilated merely upon the removal of the retainer-'niember, 32. The duplex element is normally yieldingly urged in an outward direction, tending to maintain its valve, 24, 1n engagement with its cooperating seat, 30, inv the sleeve, 12, by means of a coil spring, 86, circumscribing the rear end of the needle valve member and reacting between the spider, 14,

and a washer element, 3T, disposed against the end of the sleeve, 19, of the duplex element; Thus when the operating sleeve, 12, is threaded onto the coupling extension, element by reason of the contact of its valve, 24,7with the seat, 30, is Vgradually moved rearwardly along the needle valve member until the seat, 23, of the duplex element is `brought tightly in contact with the conical valve proper, 16,

of the needle valve member, in which position the spring, 36, is under substantial compression. It will now be apparent that when the operating sleeve, 12, ly, or outwardly with respect to the extension, 11, of the coupling, the springwill tend to hold the valve, 24, of the duplex element tightly against its seat, 30, in theend of the operating sleeve, 12, through a limited range of axial movementof said operating sleeve, determined by said cross pin, 21, and slots, 20,v and afforded by the threaded connection of said sleeve on the coupling eXtension. Such movement of the operating sleeve gradually shifts the seat, 23, of the duplex i away' from its cooperating c one, 16, of the needle valve member,'15, so as'to permit a flow of the liquid through the inner controlled thereby, either this valve seat element, 29,

is rotated opposite-v Lacasse i axially shifted outwardly to the` extent that the duplex element is moved to its outermost limit by the spring, 86, as determined by the-length of its slots,v20, then upon further rotation ofthe operating sleeve in the same direction the outer seat, 29, will be gradually moved away from the valve, 24, of the? duplex element, thereby opening the outer or supplementary valve port, 29a, which provides a substantially increased flow, approximately'.equivalent to the full capacity capable of being discharged through the eX- tcnsion, 11, of the coupling. AThe two valves arethus opened in successive order, and obviously when vthe operating sleeve, 12, is rotated inwardly after said valves have both attained their full open position, the outermost valve will be first closed,-that is, the seat, 29, will first be broughtv into contact with the valve, 24, ofthe duplex7 element, closing the orifice, 29a; and continued rotation willcause the duplex element to be gradually moved rearwardly on the member, 15, compressing the spring, 36, and gradually moving the seat, 23, of the duplex element toward its cooperating cone valve, 16, von the end of the needle valve member for closing theY orifice, 23, of the inner valve.

As is generally understood, in valves of this character when Ythe valve is just cracked7 off of its seat the flow of the liquid through the orifice controlled by the valve seat is caused to take the form of a spray and as the effective valve opening is increased, the spray gradually takes the form of a concentrated stream. Thus by this construction the innervalve member may produce either a relatively small stream or spray and when it is desired tohave a greatly increased flow or capacity the outer valve may then be opened in addition. To insure obtaining a relatively wide sprayvvhenl the outer valve is in a partially open position, l. preferably form the annular portion, 22, beyond the valve,24,` of the duplexl7 element with a reversely curved annular bead, 38, which serves to deflect the liquid in a manner to cause a Wide conical spray; the shapeV of the exterior surface of the seat, 29, and the Aretaining member, 32, being properly designed so as to assist in this result also. In Figure 4, the duplex element is shown at a position corresponding to substantially maximum opening of the outer lll) valve, which will .produce a relatively concentrated large capacity stream.

To insure against leakage between the threaded connection of the extension, 11, and the operating sleeve, l2, I preferably provide a suitable packing element 40, adjacent the rear end of said operating'sleeve and which is tightly held in pla-ce by a packing ring, 4l, threaded onto the rear end of the said sleeve, as shown in Figure l. y

Although I have shown and described a preferred embodiment of my invention, it will be understood that the construction and arrangement of parts may be varied without departing from the spirit and scope thereof. I therefore do not wish to be understood as limiting myself to the particular construction illustrated, except as indicated in the appended claims.
