HOSE-NOZZLE.

Specification of Letters Patent.

Patented July 2d, 191'? Application filed August It, 1916. Serial No. 114,899.

To all whom it may concern:

Be it known that I, CLYDE F. Blooms, a citizen of the United States, and a resident of the city of Portland, county of Multnomah, State of Oregon, have invented a new and useful Improvement in Hose Nozzles, of which the following is a specification. r I

This invention relates generally to hose nozzles, adapted for emitting a circumferential sheet of water and has particular reference to a nozzle intended for fire hose.

As well known to fire-men, the purpose of the said nozzle is to protect the fire-man holding the nozzle from intense heat by a curtain of water discharged circumferentially by the nozzle. These nozzles are also used to confine a small fire, and keep it from spreading, by enveloping it with a'curtain of water.

In order to more eflectivelyaccomplish such said purposes it is necessary that the form of the sheet or curtain of water circumferentially discharged by the nozzle be variable from a direction approximately at right angles to the axis of the nozzle, to the form of a cone of greater or lesser crosssection.

.My improved nozzle embodies said desirable features.

its construction and operation are hereinafter described, and are fully shown in the accompanying drawings in which:

Figure 1 is a partial longitudinal section of my improved nozzle, the sleeve controlling the direction of the circumferential discharge, being shown in full and dotted lines in its extreme positions.

Fig. 2 is a transverse section on theline 2-2 of Fig. .1.

Figs. 3 and 4. are diagrammatic views showing the water .deflecting sleeve adjusted to diflerent positions to thereby deflect, at diflerent angles, the sheet of water laterally discharged by the nozzle.

Fig. 5 is a fragmental view showing an alternate detail of construction of the water deflecting portion of said sleeve.

a represents the main body of the nozzle. Said body is provided with interior threads I) by means of--which the nozzle is adapted for attachment to the standard end coupling of a fire hose. A shoulder c and packing gasket 01 are provided as a seat for such coupling. Concentric with the body a and extending therefi'om is a tubular. member 6 through which the main stream normally flows. Said tubular member is provided with a valve, thehandle of which is indicated by f and this valve forms a means by which the flow, through the said tubular member 6, may be regulated or entirely out ofl. The inner end of the tubular member,

is connected with the body a by the radial I web members 9.

It is to be noted that these web members are made with converging sides, the purpose of which will hereafter be pointed out.

The tubular member 6 is also provided with an exterior flaring web it the base 2' of which .is concaved and polished. The

outer end of the bodya is made with an i. e., a base ring a and a deflector 0. The

latter is rigidly attachedto the base ring 7 by the screws 9.

The deflector is made with a conical bore 7*, the surface of which is adapted to seat on the rim of the circumferential port of the nozzle. Whenever the screws g are removed, the deflector piece 0 may be removed and the valve seat thus ground to a true is used for fighting fire at close range, the

deflector a is moved to the position shown in the broken lines of Fig. 1.

The circumferential port 70 will then be entirely open and a cylindrical, conical or lateral water curtain will be thrown from said nozzle, according to the adjustment of the deflector c. The convergence of the sides of t I The outer end of the deflector, is

member 9 operates to close any break in the the nozzle, or to envelop a particular spot in which a fire is burning and confine the fire to that spot. The latter action is always desirable in fighting a fire, and a curtain of water is most effective for that purpose, while the discharge from anordinary nozzle frequently throws an undue volume of water on the fire, and in this way does much avoidable damage. The adjustment of the deflector s for the purpose of throwing the curtain of water in the form of a cylinder or a cone of greater or lesser crosssection is represented in Figs. 3 and 4e.

In Fig. 5, l have shown an alternate con.- struction for the deflector. In this view, the deflecting surface is made with a series of conical plane surfaces, 2?, instead of the curved surface shown in the other views,

I claim I 1. In a nozzle of the character described, the combination of a chambered body pro vided with a rim and a valve-controlled axial tubular member theinner end of which extends into the body, such member being made with a circumferential flaring deflecting flange, a sleeve longitudinally movable on the extremity of said body, the extremity of the sleeve beingprovided with a bowlshaped water deflecting piece including a rim of substantial width the inner face of which deflecting piece is substantially concaved at the base, then cylindrical, and. convex toward the rim, the rim of the body and the flange of the tubular member being adapted to provide a circumferential port,

and said sleeve having a portion adapted to close said port when the sleeve .is in one position.

2, In a nozzle of the character described,

the combination of a chambered body provided with a rim and a valve-controlled axial tubular member the inner end of which extends into the body, such member being made with a circumferential flaring-flange having a concave deflecting surface, a'sleeve longitudinally movable on the extremity of said body, the extremity of the sleeve being provided with a bowl-shaped'water deflecting piece including a rim of substantial width the inner face of which deflecting piece is substantially concaved at the base,

then cylindrical, and convex toward the rim, the rim of the body and the flange of the tubular member being adapted to provide a circumferential port, and, said sleeve having a portion adapted to close said port when the sleeve is in one position. 7

3. In a nozzle of the characterdescribed, the combination of a cylindrical chambered body provided with a rim and a valve-controlled axial tubular member the inner end of which extends into the body, the periphing piece including a rim of substantial width the inner face of which deflecting piece is substantially concaved at the base, then cylindrical, and convex toward the rim, the rim of the body and the flange ofthe' tubular member being adapted, to provide a circumferential port,and said sleeve having a portion adapted to close said port when the sleeve is in one position.

4. In a nozzle of the character described the combination of a cylindrical chambered body provided with a rim and a valve controlled axial tubular member the inner end of which extends into the body, the periphcry of such inner end being made conical to widen the space-between the inner end opposed faces of the body and said member, such member being made with a circumferentialflarin flange having a com cave deflecting sur ace, a sleeve longitudinally movable on the extremity of said body, the extremity of the sleeve being provided with a bowl-shaped water deflecting piece including a rim of substantial width the inner face ofwhich deflecting piece is substantially concaved at the base, then cylin drical, and convex toward the rim, the rim of the body and the flange of the tubular member being adapted to provide a circumferential port, and said sleeve having a portion adapted to close said port when the sleeve is in one position.
