JET AND SPRAY NozzLE.

Application filed. January 13, 1927, Serial No. 1150,910, and'in Australia January 11, 1926.

This invention relates to a combined jet andy spray nozzle or litting for attachment to garden hose or other water pipes'an'd` the like. More particularly the invention refers to that class of device whereby the stream water passing from the nozzle may be caused to issue either' as av jet' or in the form of a. line spray.

existing devices ofthe above class the sj ray is usually form-ed by means of a conical' member' suchA as a needle valve placed in the path of the liquid and adjustable so that the water stream may be spread sidewardly as it leaves the nozzle or may be concentrated toA form a jet.

rnobj'ecti'on to such existing devices is that the spray projected from the nozzle is usually l'iollow7 or ofy annular form so that when the device is kused for instance in an upright position toy act as a sprinkler, the `water falls to the ground in a ring, the area within which is not water-edi 'Ehe prima-ry object of the present invention is to overcome the abovementioned ob ject-ion and' to provide an'r improved nozzle v-:liereby the liquid stream may be readily varied from a relatively large and powerh ful jet 'to av dense spray in which the water is evenly distributed over the whole central areaV within the marginal limits of the spray.

The invention also aims at providing a simple and highly efficient construction whereby the foregoing improved results Vare obtained and in addition the water stream may, when' desired, be. concentrated into an extremely narrow jet so that it4 is. projected for a relatively longV distance even under conditions of low water pressure;

Referring to the drawings which form part of this specificationz.-

l Figure 7 shows theinvention in use as an upright sprinkler on a suitable stand or support Figure 8 shows the invention applied to an inclined directoror nipple on a horizontal water supply pipe.

A. device in accordance with the invention comprises a hollow metallic fitting or socket member 2.the inner or rearv end of which is internally screw threaded as at 3, for en'- gagement with the usual crewed hose director l or any other suitable conduit through which liquid is supplied to the nozzle. A liquid; inlet passage 6 is 'formed' centrally through the socket member 2 and its outer or forward end is externally threaded to detachably receive a valve carrying member 7;

The valvexcarrying' member 7 has a longitudinal: centralpassageway 8 which slidably stitutesv a transverse partition between vthe -valve chamber 12 and the discharge orifice f8 hereinafter described, are longitudinal passa-ges '111 which are tangentially inclined or'zof somewhat spiralV formation so that liqthrough .them is given a whirl- Rearwardly of the valve chamber 12. the member 7 is internally screw threaded to engage the external thread of the socket member 2 which is provided with a, shoulder 13 against whi'chthe rear eX- ingmotion.

rtrem'ity of said member 7 may abut.

rJfhe valvecarrying member 7 is alsoscrew threadedextern'ally as at 14 to receive an internalthread of a longitudinally adjustsleevemember 16 which is completely open at its inner end, andv is partially closed at its outer end by a front transverse wall 17 having formed therethrough a centra-l water discharge orilice 18. The edge of this oiiice ispreferably of tapered or conical formation so that it diverges outwardly as shown.

valve seating 19 is'formed in the front or end ofthe socket member 2 vto en* i hevalve..carrying` member, which con-k gage the rear conical face 23 of an enlarged head on the aforementioned valve 9. `lThe stem of this valve is of hollow or tubular form andy has adjacent its inner end a lseries of radial ports 22 which are adapted to4 provide communication betwe-en the internal passage 2() of said tubular valve stem and A the valve chamber 12- formed between vthe valve carrying member 7 and the socket member 2.

A front face or shoulder 24 of the valve head is adapted to engagea corresponding seating 26 formed at the inner end `of the central passage 8 through the valve carrying member 7 whereby communication between the inlet passage 6 and the ports 22 ofthe tubular valve stem may be cut oi when desired as indicated in Figure 3. Y

For certain purposes, particularly when the deviceis to be used as a nozzle for garden hose a narrow central bore or `aperture 27 is preferably formed through the head ofthe valve 9 so that the inlet passage 6 is'in permanent'communication with the internal passage 20 through the valve stem. In some cases the passage 27 may be eliminated, so that when the parts are in the position seenin Figure 2 the discharge of liquid is entirely eut off. j

The internally threaded rear end of the adjusting sleeve member 16 is preferably screwed onto a threaded rinor or lock nut 28 which freely but closely enclrcles the socket member 2 and prevents leakage as well as serving as a stop to prevent the sleevefrom being entirely withdrawn from the fitting.

. The socket member 2, the nut 28 and the sleeve 16 ymay be each provided with milled or like external faces as shown to facilitate assemblage, adjustment and dismantling of the parts.

Vith the device in use the dischargeof liquid may be restricted to a narrow but elongated jet by moving the adjusting sleeve 16 to its innermost position as .seen in Figure 2 so that owing to the engagementof the Asleeve wall 1.7 with the front end of the valve stem the rear face 23 of the valve head contacts with the seating 19 formed at the `front end of the socket member 2, thus cutting oli' the water inlet passage 6 fromthe passages 11 and the radial ports `22 of the valve. The water is Athus'permitted tovissue only through thesmall central aperture 27 which is` always open and enables a long `narrow jet of liquid to be delivered even with a very low water pressure. With the IVhen it is desired to project the liquid in a larger jet `the adjusting sleeve 16 is screwed outwardly so that the valve head is forced by the water pressure to leave'the seating 19 of the socket member 2. By positioning the sleeve 16 as sten in Figure 4 such outward movement of the valve is arrested before the shoulder 241 ofthe valve head engages the seating 26 at lthe inner face of the valve carrying member7 so that the liquid passes through the radial ports 22 as well as the-.aperture 27 into the internal passagev 2O of the valve stem and thence out through the discharge orifice 18 in the end wall 17 of thev adjusting sleeve. In this position the outer end of the valve stem abuts against the sleeve wall 17; and as Said stem is of greater diameter thanV the discharge orifice 18 and is concentrically aligned therewith, the passages 11'are cut off from the` dischargeorifice so that a straight jet of water from the hollow` valve stem Vis produced.

In either of the positions illustrated in Figures 2 and 4 the bevelled front edge 10 ofthe valve stem engages within .and against the inner edge `of the discharge orifice 18,

thus positively preventing side play of the way of the valveupassage 20.

Upon screwing the adjusting sleeve further-outwardly as seen in Figure 3, the water pressure forces the valve head against its seating V26 at the inner faceof the valve yadjusting sleeve is now clear of the adjacent end of the valve stemso that the discharge orifice 18ris placedincommunication with the inclined passages 11 in the valve carrying member. As the `wat/er passes through these latter passages it isrsubjected to a whirling action; andas it issues from the outer .end off `the passages 11 it impinges against the sleeve wall 17 whereby it is caused to combine withthe jet passingfrom the central aperture 27 and to issue from the discharge orificeV 18 in the Yform `of a iinely atomized sidewardly extending spray wherein the water is effectively distributed ovcrthewhole central area within the marginal limita of the spray as previously mentioned.n By manipulating the sleeve 16 so as to vary the distance between the wall 17 and the front end `of the valvestem the angle and width f of the spray may bereadily.alteredaccording to requirements.
