HOSE NOZZLE Filed Dec. 5, 1932 lar lg HENRY N/CHOLS Patented Dec. 1934 UNI-TED STATES vPAT-ENI F F ICE i'iis'invention is a hose nozzle of the type constructed to controlthe shape and character of the stream of liquid tol be delivered thereby.

One of the objects ofthe invention is to provide a nozzle 0f the character described, having a-Shutoff valve positioned for convenient and effective control by the operator, while the nozzle is in use. A further object is to provide a nozzle of vthe character described having means so arranged that the operator, by a simple manipulation .may cause the water to be delivered in theformof a powerful spray or in a solid stream, as maybe desired, A further object istovprovide a nozzle having means for substantially increasing the delivery pressure for a given volume vof flowr'of- Water. A further object is to provide a nozzleof the character mentioned constructed `of .but few parts, sov that vit maybe cheaply manufactured and will not readily get lout of order..Afurther object is to provide ahose nozzle which is particularly valuable in connection with .theswashing of vehicles, but is not limitedto such use. l

AThe invention will'be hereinafter fully setforth and particularly pointed 'out in .the claims. Y

In the accompanying drawingzj Figure 1 is af-longitudinal .sectional view illustrating a hose nozzle constructed in,;accordance with the invention, showing theparts,adjustedto increase the delivery pressure of a streamof-Water to provide a powerfulspray. iFigurevgZ is.,.a similar view, showing the parts adjustedto deliver a solid stream.` Figure v3' is adetail sectional View illustrating a ,slight modication.

Referring to the drawing,vand vparticularly t0 Figure 1, the nozzle is shownasprimarily Aconstructed of a main casing A and a. nozzle, member B. g The main casing Ais provided with a nipple 10 which is shaped to be linserted intoone' end of a exible hose H, said nipple communicating with lthe inlet portion ofl -a valve Chamber 11'." *Said 1 force, creating a reduced pressure in the space `inlet portion isproyided with -a threaded Opening in its bottom, normally closedv by an abutment plug 12. Located within said valve chamber Ais a y transversely disposed valve seat 13, dividing the said chamber into an inlet and an outlet portion, communication between the last mentioned portions being controlled by a valve 14. Said valve is normally biased to said seat 13 by a spring 15, one end of which bears against the underside of said valve, its other end resting upon said cap 12. A stem 16 formed integrally with said valve is extended upwardly through a stuffing box 17 in the top of the casing A, and is provided with a head or button 18, against which a nger of the operator may be pressed, so as to readily move 21. --with--aprotective covering 30, such as a piece of '-1, t'hevvaterY maybe turned on at the source of supply, -such as-a lhydrant (not shown), but 'ilowjthrough the valve chamber to the nozzle member will be prevented by a valve 14. The @instant that` the valve is unseated, however, in fthe Ymanner already described, water will ow jthroughfthe valve chamber and the delivery chamber, being discharged outwardly through fthe valve to unseated position against the tension of the spring. In this connection it will' be readily noted that pressure yupon the valve stem against -the tension of the spring will unseat said valve,

and that the spring, aided by the flow of the Water 5 will instantly `seat the valve as soon as said unrseating pressure is removed.

The outletportion of the -valve chamber 11 is separatedfrom adeliver-y chamber 19, by a transverse wall 20 having a central opening, the outer l2 side of -said wall being` shaped tc provide a valve seat121. The discharge end of said chamber 19 is providedwith an internally threaded opening, as

i shown.

The nozzle member B comprises a nozzle tip i5 25, having a threaded bushing-like portion 26 adjustably-engaging 'the threaded discharge end of the chamber 19, and carrying a concentrically positioned spray member 27. Said spray memlber'is supported -bya spider 28, preferablyy inte- 20 gral Ywith the'portion 26, and is provided with an enlarged-coniform base 29, having beveled edges forming a valve complemental to the valve seat If desired,'the nozzle tip may be provided hose, `trprevent it from scratching .or lotherwise 'marring the nish of a vehicle, while the nozzle is in use for` vvehicle-washing purposes.

With the parts positioned `as shown in Figure thebore of the spray'member 27. Owing to the reduced diameter of said bore the Vwater is forced therethrough at high speed with considerable 40 surrounding the base 29. As the stream leaves stantly expandsradially, striking. against the inner surface of the nozzle tip25, so that itis nal ly discharged in the form of a powerful spray, which will quickly cleanse any surface with which it may come into Contact; or it will be discharged over a considerable distance if the device is being used for rrigating purposes. If a solid stream is desired, the operator grasps the covering 30 and slightly unscrews the nozzle tip 25, thereby moving the valve-like base 29 of the spray member 27 away from the valve seat 21, as shown in Figure 2. The effect of this adjustment is that upon the unseating of the valve 14, the water will not only flow through the bore of the spray member 27, but will divide so that a portion thereof also passes around the base 29 of the member, breaking the vacuum around said base member, the divided stream being consolidated Within the nozzle tip 25 from Which it Will be projected in a solid stream and much lower pressure.

if a more powerful spray is desired than is possible With the construction already described, the same may be obtained by means of the modified form of nozzle tip shown in Figure 3. Referring to said ngure, the spray-member 27e is carried by a bushing 26a, shaped to engagethe` threaded discharge end of the chamber t9. Said.

spray-member is threaded to be engaged by a complemental threaded portion of a nozzle `tip 25a, which has a ared discharge end 31,. in Which is mounted a pin 32 Which rotatably supports a ball 33. The bushing 26EL is prov-idedwith a flange 34 by means of which it may be readily manipulated, as desired. In practice the stream delivered by member 27a impinges upon` the ball, causing the ball to rotate and to alsol spread the stream in an obvious manner. If a solid stream is desired the bushing 26ers unscrevved so as to unseat the spray member 27a.

The advantages of the invention will be readily understood by those skilled in the art to which it belongs. In this connection it Will be observed than an exceedingly simple form of valve is provided, which maybe readily and conveniently manipulated to selectively provide a powerful spray or a solid stream, as may be desired.L It will also be noted. that although the nozzle may be used for any desired purpose Within the limits of its construction, it is particularlyy adapted for use in Washing automobiles and other similar vehicles, because of the ease With which it may be adjusted to increase the delivery pressure or to discharge a normal soli-d stream as circumstances may require.

Having thus explainedthe nature of the invention and described an operative. manner of constructing and using the same, although Without attempting to set forth all4 ofthe forms in which it may be made, or all of the forms of its use, what is claimed isz- 1. In a hose nozzle, a casing having a delivery chamber provided with a valve seat, a bushing adjustably engaging said casing, a concentrically positioned tubular spray member carriedv by said bushing and extended axially into said delivery chamber but of less diameter than said chamber, said spray member having a member complementa-l to said valve seat, said spray member being so constructed and arranged as to selectively convert fluid passing through said opening. to the form of a spray or of a solid streamin accordance With `adjustments of the spray member with respect to said valve seat, and a flared nozzle tip mounted' on the discharge end of said spray memberand having a ball' rotatably mounted in the discharge end thereof.
