posi-tion so thatwhexr the= spray nozzle is not acrr tually` being usedy the flow of water-is automatically andi completely.` Shut. oil.` The present invention whichembodies such*l a spray nozzle is provided: withl a pistol-grip.` handle and operating; lever extending beside the handle and'. operated bya soecall'eddsqueeze grip.

Inl the form shown. of, the present: inventiom the type of spray produced' by-the; nozzle is con-` trolledfby a metering: pin located axially within the nozzle and carrying a cylindrical valve merm ber which engagesa. valvefseat immediately to. the rear of: the nozzle and extending;abnuttlief` metering pin, the position of" the: forward end. of the.` metering pin relative to. the nozzleandthe. degree: of: opening of'fthe. valve, controlling the type and. volume of spray. The:metering-Diniemovedzrear wardly by the operatinglever; andthe connection.

between the lever andi metering pin is: adjustable;

so that, when. the lever is moved?, aga-inst. the pistol-grip handleas in normali operating', posi.- tion, thev metering pin; andi valve are; moved rear;-` wardly the proper amount-kier theI particular type of spray desired. This adjustment: once` having been made, the same` character and volume oi' spray: may be obtainedi repeatedly by,` movingthe, operating lever against. the grip.

As described' herein, applica-ntfs. construction includes a. rubber cover for protecting the spray nozzleI against damage, which is. held in. place solely by the interfitting of. the; cover and,L hous.-` ing, and which may be removed and replacedL without the use of tools or disassembly of the housing and without damage.- toi thee cover.

An object of the present invention is to prof.

vide a` combined valve and spray nozzle of' the` type described'. in which the type.` andi volume of spray are; controlled by a valve and metering pin.; to provide such a nozzle in. which the same charactcr' of'V spray may be; easily obtained? in successivev uses of the. nozzle without the necessity of adjustment foieach use.; and to; provide a generally improved valve and spray' nozzle which is. simply and easily manufactured and dependable and convenient inoperation.

Other objects of the. invention are.- to provide. a, combined valve and spray nozzle of simplifiedconstruction in which most of. the: working parts n al are` contained within a` conveniently'removedsube assembly, and to provide a rubber cover for-the,

housing of such a nozzle that is easily removable and replaceable.

Other objects and objects relating` to economiesV of manufacture and' use will` be more apparent` from the1 detailed description to follow,

My invention isA clearly defined in the appended claims. Where parts` are, for clarity and convenience, referred to on the basis of their oriented position shown in the accompanying drawing, no-` limitation as to positioning of the entire structure is to be implied, since it will be understood that the entire structure may be usedin; any position. Also in both the description and the claims, parts at times may be identied by specic names for clarityV and` convenience, but such nomenclature is to bev understood-g as having the broadest'meaningconsistent with the context and.

with the concept of my invention as distinguished from the pertinent priorart. The best form in which I have contemplated applying my invention is illustrated in the-v accompanying drawing forming part of this specification, in which:

Fig. 6 is a View similar to.l Fig. 4. showing the metering pin and valve in position to produce a coarse spray or stream.

Fig. 7 is a perspective view of therubber cover.

Referring now to the drawings, the combined valve and spray nozzle of the present invention has` .a unitary, generally T-shaped housing IU consisting of a horizontal, bore portion Il and a, pistol-grip portion I 2` intersecting the. bore portion H between its ends. An operating lever i4 is pivotally mounted on the rear side of the pistol-grip portion I2- and controls the flow of water-through thenozzle. thelever being actuated by movement towards the portion I2 of the housing. The specic construction and operation ofthe lever I 4 will be explained in more detail hereinafter.

The bore portion lfl of the housing is provided with a. bore l5, the forward end' (left end as viewed in the drawings) of which threadedly receives a nozzle I6 which has a central aperture Il' coaxial with the bore. The -bore I5 has a radial, inwardly projecting step i9 towards the rear end of the bore, and the bore may have a rearward extension I8 beyond the step i9 and of the reduced diameter of the stepped portion of the bore.

The pistol-grip portion I2 of the housing lil is provided with a longitudinal inlet passage 25 intersecting the horizontal bore a short distance behind the nozzle I6. The lower end of the inlet passage 2Q may be threaded to receive a hose adapter 2|.

A metering pin 22 is axially located Within the bore i of the housing, the forward tapered end 23 of the pin being received within the nozzle It at the forward end of the bore. A circular valve member 24 is coaxially mounted on the metering pin a short distance behind the tapered end 23 thereof, the valve member having a circularly grooved, forward face forming a forwardly extending peripheral flange 25 for engaging a valve seat. The metering pin is normally biased forwardly (to the left as viewed in the drawings) so as to urge the peripheral flange 25 of the valve member 24 against a resilient rubber or rubberlike annular valve seat 2S positioned against the rear side of the nozzle i6. Preferably, the nozzle I6 has a rearwardly directed flange portion extending about the aperture Il' to aid in holding the valve seat 26 against displacement.

The metering pin 22 is axially supported and guided in the bore I5 by a generally cylindrical stuffing box 29 received within the bore and a cylindrical plug 30 received within the rear extension I3 of the bore. The stuihng box 29 has an outer diameter which is a sliding fit within the bore I5, and the forward end of the stuffing box is provided with a peripheral step 6I to receive an annular, resilient rubber or rubberlike packing ring 32 and form` a fluid seal between the bore and the stuffing box.

The stuffing box 29 is provided with an axial hole 34 for slidingly receiving the metering pin 22 and a packing chamber 35 receiving resilient packing 38 for forming a fluid seal about the metering pin. The packing 36 is held in sealing relation above the metering pin by an annular follower ring 31 and a helical compression spring 39 extending about the metering pin. The rear end of the packing chamber is closed by an annular plate 4@ apertured to receive the metering pin and held in place by swaging in the side wall of the stuffing box.

The stuffing box 29 is held against the step portion I6 of the bore I5 by a cagelike cylindrical spacer 4I extending between the valve seat 26 and the forward end of the stufng box. The construction is such that, upon screwing the nozzle IE into the forward end of the housing I0, the spacer bears against the packing ring 32 of the stuffing box so as to hold the stufling box against the step I9 and, at the same time, laterally expand the packing to form a fluid seal between the stufng box and the bore. The forward end of the spacer 4l compresses and laterally expands the outer peripheral portion of the valve seat 26 so as to form a fluid seal about the periphery of the valve seat. The spacer 4I is provided with one or more large holes through which fluid passing from the inlet passage 20 into the bore I5 passes and a helical compression spring 42 extending about the metering pin 22 between the stuffing box 29 and the valve member 24 biases the metering pin and valve member forwardly. This spring is located within, but not connected with, the spacer 4 I.

A collar 44 is threadedly received on the metering pin 22 behind the stuffing box 29. This collar which is generally cylindrical has a pair of diametrically opposed slots 45, 45 extending chordally of the collar and receiving the parallel ends of a bifurcated valve-actuating portion 46 of the operating lever I4.

The operating lever I4 is pivotally mounted on the outside of the housing I0 at the intersection of the horizontal bore portion II and the pistolgrip portion I2 by a pivot pin 43, and an arm portion 48 of the lever extends downwardly to the rear of, and spaced somewhat from, the pistol-grip portion. The arrangement is such that, upon moving the arm portion 48 of lever I4 towards the portion I2 of the housing, the metering pin 22 and valve member 24 are moved rearwardly so as to open the valve and provide a fluid spray through the nozzle I6.

The cylindrical plug 33, which is slidingly received within the rear extension I8 of the bore I5, is non-rotatively secured to the rear end of the metering pin 22 by a transverse pin 41 extending through these parts. The rear end of the plug 30 may be provided with a transverse slot 49 for receiving a screw driver or like tool for rotating the metering pin 22. Since the collar 44 is held against rotation by engagement of the bifurcated portions 46, 46 of the operating lever in the slots 45, 45, rotation of the metering pin 22 serves to move the collar axially along the metering pin in either direction so as to adjust the initial position of the lever and control its spacing from the rear side of the pistol-grip portion I2 of the housing.

Since the grip portion I2 of the housing limits the opening movement of the operating lever I4, the degree to which the metering pin 22 may be moved rearwardly upon operation may be positively controlled in this manner; e. g., the further that the collar 44 is moved forwardly on the metering pin 22, the further the arm portion of the operating lever I4 is moved away from the pistol-grip portion I2 of the housing, and the further the metering pin 22 is moved rearwardly when the lever is moved against the pistol-grip portion in operating the spray nozzle.

rI'he character of the spray is controlled by the position of the tapered forward end 23 of the metering pin within the nozzle I6 and also to some extent by the degree of opening of the valve. As the metering pin 22 is moved rearwardly, the valve member 24 is withdrawn from the valve seat 26, the parts being in the general position indicated in Fig. 4 and producing a fine, mistlike spray.

As the metering pin is drawn rearwardly further, the character of the spray changes to a light spray which becomes coarser as the metering pin 22 reaches the position indicated in Fig. 5. As the metering pin is further withdrawn to the position indicated in Fig. 6, the spray becomes a more or less solid stream.

By adjusting the position of the collar 44 on the metering pin 22, the distance that the metering pin is drawn rearwardly when the spray is operated is controlled and, thus, the character of the spray is determined. After once having been adjusted, the same type of spray can be obtained upon each operation until the adjustment is changed for any reason.

For prolonged spraying, a pivoted loop 50 is #terence provided. om the; end? of; the; vportiers Il: ot the iurusingrrwhichmaarJ be rotated;into.spositicrr` over: endl of ther operating lever Mi t hold;E the:4 levery against the:A portion-1 L2 holditlnr parts: of the'. spray` nozzle; in operating: position.`

The spray; nozzle.A is` provided:` with a resilient.v moulded-rubber4 jacket or cover 5+. which serves4 to: protect: the spray nozzle 'e against y damage f and.` serves to prevent scratching of? other; objects.: byJ theispray nozzle., This jacket. which; is' shown; im Eig. 7,. is` shaped to yoverlie. the housing; Ill and.- nozzlee [Gland: has openings. coinciding with each. endl-of thebore. l5 andtheoutcr. encL of the inlet.- passage: 2li.` The. jacket.. 5J. is. provided. with. a.z slotlz extendingfor ashort. distance alongfthe` rear. `side. of4 the pistol-grip. portion.'V and under-J siden of, the horizontal. borev portion. froml the, int'ersection. thereof.;l The slot. 52'. provides clear ance. for. pivotalmovementlof. the operating lever 11 including thebifurcatedpontion I6; An ad? ditional.' feature of this jacket. is that the jacket may be applied or removed' from the. spray nozzle housing I without disassembly of the housingv and' unit damaging the jacket. This is accompli'shed' bypassing the pistol-grip portion l2' of* the housing througnthe slot 52 of thel jacket: 5r andi downwardly within the corresponding portionv of the jacket; The forward' or nozzle` endi' of the` bore portionv H of: the' housing is then` 'enteredthrouglr the-slot' 52 and into the corre-- spendingvr portion of' the jacket; The jacket is= engaged* about'thcrear-end of the bore portion Il of-` the `housing by stretching. this portion of the jacket somewhat' so as to pass the rear and central portions ofthe housing through the slot 52, thejacket then contracting' and assuming thek positionindicated in Fig. l.

The. operating portions of thespray nozzlelmay he; easily disassembled for cleaning, repair, or replacement by withdrawing the` pivot pine holding the operating lever" to; the` housing lllF and then withdrawing the operating. lever from the collar M. Then, upon unscrewing the nozzle i6, all of the parts contained within the bore I5 may be Withdrawn from the forward end of the bore. The metering pin and stuing box assembly may then be disassembled if desired. To reassemble the spray nozzle, the disassembly operation is reversed.
