HOSE-NQZZLE.

To all'who m it may concern Be it known that I, HENRY 611333 3. citizen of the United States, a nd a resident of Chicago, county of. Cooln'and State of Illinois, have invented certain new and useful Improvements in Hose-Nozzles, of which I do declare the following to be a full, clear,

and exact description.

The present invention, while susceptible of wider application, has more particularly for its object to provide an improvement in that class of hose nozzles whereby the water' from the hose mayv be regulated and controlled so that it will issue-either in the form of coarse spray, fine spray or in a solid stream, an example of this type of hose noz- "zle being shown in an application for Letters Patent filed by me January 2, 1913, Serial No. 739,875.

The invention relates more particularly to improved means for effecting the automatic cutting oil and manualcontrol of the stream of water and consists in the features of novelty hereinafter described, illustrated in the accompanying drawing and particularly pointed out in the appended claims.

Figure '1 is' a view in side elevation of a hose nozzle embodying my invention. Fig.

'- 2 is a view in central vertical section through Fig. 1." Fig. 3 is a view similar to Fig. 2,

. but showing the parts in difierent positions.

Fig. 4 is a view in cross section on line 44:'

of Fig. 1, parts being shown in elevation.

In the accompanying drawing, A designatesthe body of the nozzle, the outer end of which is formed by the flaring portion a and an annular contracted portion a having an opening a therein, the annular contracted portion a forming a seat for a valve by which the flow of water will be cutoff, as will hereinafter more fully appear; The chamber 6 of the body of the nozzle is shown as of substantially uniform diameter from adjacent its inner end to the valve seat a at its outer end. The body of the nozzle is .slidably mounted upon the hollow valve stem B which extends within the chamber 6 and the hollow port aof which communicates with the chamber through one .or more ports 9.

The outer end of the valve stem B is'provided with an enlarged beveled portion 10,

preferably slightly larger in'diameter than theopening a at the outer end of the body A of the nozzle, this portion 10 serving as Specification of Letters Patent. Patented Nov. 2,1915. Application filed January 14,1913. Serial E0. 742,014. I

I a valve which, when forced against the valve seat a. at the outer end of the nozzle, will serve to cut oil" the flow of water through the opemn a Preferably, there projects from, the va ve 10,. a double cone 12 slightly smaller in diameter than the. opening a at the end of the body A. When the-parts are in the position shown in Fig. 2, with the valve 10 closed against the seat a, the flow pf water through the nozzle willbe'cut ofi", but'by shifting the body portion upon the Valve stem until the double cone 12 is more or less within the contracted opening a at the endof the nozzle, the character of the stream of. water can be modified so as to cause such stream to issue from the end of a cap 18 that is screw threaded, as at 19, to

the inner end of the body A of the nozzle. Preferably, packing rings or washers 21 and 22 are interposed between the-cap 18 andthe end of the spring 16. The tension of the spring 16 serves to hold the parts nor mally in the relative positions "shown in Fig. .2, that is to say, with the valve 10 closed against the valve seat a at the outer end of the nozzle. The cap 18 fits upon the hollowstem B and slida-bly supports the body portion of the nozzle thereon, and the washer 21 forms a water tight joint between these parts. Thecollar 15 aids in guiding the longitudinal shiftofthe body portion of the nozzle upon the hollow-stem.

In assembling the parts, the cap 18 and on the spindle and thecollar fixed thereto.

The body portion A of the nozzle is then passed over the spindle and the collar 15 and threaded into the cap 18.- The cap 18," packing washer 21 and packing ring 22 fit upon the spindle to properly'support the body portion of the nozzle and guide its axial -movement. such size that it aids in supporting and The collar 15 is also of guiding the axially movable hollow body portion.

To edect the shift, of the nozzle- A. upon the hollow spindle .B to thereby move the valve seat a relatively to-the valve 10 and cone 12, a'hand lever is interposed between these parts and is arranged to move the body of the nozzle against the. tension of the spring 16. In the preferred construction shown, an angle lever C is pivotedat 25 to a lug .26 that projects on an enlarged, interiorly threaded coupling 27 upon the inner projecting end of thehollow valve stem or spindle B. The lever C is of angle form and one arm 0 extends between the enlarged,

coupling 27 and the cap 18 at the inner end of the body portion of the nozzle. This arm is bifurcated to straddle the hollow stem or spindle B, as most clearly shown in Fig. 4c. The other arin of the lever C which forms the finger piece projects rearwardly over the coupling 27, so that it can be conveniently manipulated by the thumb orhand of the person using the hose to which the nozzle is attached.

When the parts are in the normal position shown in Fig. 2, the flow of water through the nozzle will be cut off because the valve 10, at the end of the spindle B will be against thevalve seat a adjacent the outer end of the nozzle A. If, however, the person using the hose depresses, as with the thumb, the free end of the lever C, the body of the nozzle B will be moved forward until the valve 10 is retracted from the valve seat a and water is permitted to flow through the opening vaz adjacent the outer end of the nozzlerA, Obviously, the extent to which the cone 12 is drawn through the opening a will determine in'this construction, as In prior constructions, the character of the stream of water discharged through the nozzle, that is to say, whether the stream shall issue as a solid stream or more or less broken up into spray. ,As soon as the pressure 'on the free end of the lever C is released, the spring 16 will retract the nozzle A upon the spindleB from the position Having thus described. my invention what I cla'imas new and desire to secure by Letters Patent, is :i

' 1. A hose nozzle comprising a hollow stem having a coupling at its inner end and a valve at its outer end, a hollow body portion slidably supported and guided upon nieaoia said stem and having a discharge opening at 'its outer end with which said valve cotiperates, a spring interposed between said stem and said body portion for normally holding said valve in closed position, and a pshifter interposed betweensaid parts for shifting said body portion upon said stem against the tension of said spring, substantially as described. I

2. A hose nozzle comprising a hollow stein having an enlarged coupling at its inner endand a valve at its outer end, ahollow body portion slidably supported-and guided upon said stem'and having a discharge port at its outer end with which said valve oooperates, a spring interposed between said stem and said body portion for normally holding said valve in closed position, and a shift lever projecting into the space between the inner end of said body portion and said enlarged coupling and pivotally mounted on one of-said parts for shifting,

said body portion upon said stem.

3. A hose nozzle comprising a hollow valve stem having an enlarged couplingat its inner end and a valve at itsouter end, a body portion slldably supported and guided upon said valve stem and having a discharge opening at its outer end withwhich said.

valve cotiperates, a spring interposed be tween said stein and said body portion for normally holdingsaid valve in closed position and an angle lever pivotally mounted upon said coupling and having a finger lpiece rearwardly projecting over sai coupling and an inwardly projecting bifurcated part arranged to straddle said stem and engage said body portion to shift the same outwardly upon said valve stem against, the tension of said spring, substan; tially as described.

4. A hose nozzle comprising a hollow stem having a coupling at its inner end and a valve at its outer end, a body portionsurrounding said stem and having a discharge opening at its outerend with which said valve coiiperates, a cap and Washer mounted on the inner end of said body portion and engaging-said stem to slidably support and guide said body portion on said. stem, a

guiding" collar separate from but fixed to said stem within said body portion, a spring coiled about said stem and interposed between said .collar and saidcap and washer, and a shift lever. interposed between said stem and said'body portion for shifting the latter outwardly upon the stem against the tension of the spring, substantially as 16.6"
