flayasi fi 6721712.

Hudson Manufacturing Company, Chicago, 11]., a corporation of Minnesota Application February 21, 1957,Serial No. 641656 3 Claims. 01. 239-354 The present invention relates tomanually-operated sprayers and more particularly to a novel spray nozzle for controlling the discharge from a compression sprayer of the type employed for spraying household and garden insecticides, disinfectants and other sprayable solutions for pest and diseasecontrol', mothproofing, deodorizing, etc.

Among theobjects of the'present invention is the provision in a spray nozzle of a novel'shut-ofbinwhich by a simple camming action the nozzle may bereadilymoved to a spraying position for the discharge of a spraysolution or moved to shut-off position in which=thenozzle is sealed against leakage or discharge. a a a The present invention further 'comprehends a compression sprayer provided with novel means for adjusting-and opening and closing the spray nozzle by simply flipping a readily accessible pin or projection on the nozzle.

Another important'object of the present invention is the provision of a novel nozzle'assembly inwhich the parts may be readily assembled and disassembled-and in which the supply tube is made detachable for'quick removal from the assembly for cleaning.

A further object is to provide a nozzle assembly for manually-operated sprayers of th'e compression or continuous type in which thespray nozzle isreadily-adjustable from open or operative position to closed orshutofl position and when in closed position scaling is effected in a novel manner. Y r x Further objects are to provide a construction of maxi mum simplicity, efliciency, economy and ease ofassembly and operation, and such further objects, advantages and capabilities as will later more fully appear and are inherently possessed thereby.

In the drawing:

nited States Patent Figure l is a view in side elevation ofia manually-operated sprayer in which is embodiedthe novel spray nozzle of the present invention.

Fig. 2 is a fragmentary enlarged view,part inside elevation and parts in vertical cross section, of thenozzle and forward end of the s rayer.

Fig. 3 is an enlarged top plan view of the nozzle assembly of Figs. 1 and'2, .withthe nozzleadjustedto fully open position anditheihead of the shut-off pin broken away to more clearly disclose the arcuate' slot.

Fig. 4 is a view in vertical cross section through the nozzle assembly with the nozzle in fully open position, the view being taken in a plane represented by the line .'-4 of Fig. 3 and viewed in the direction of the arrows.

Fig. 5 is a View similar to..Fig.. 4'but with the nozzle rotated or adjusted in its encompassing holder to closed or shut-ofl position by movement of the nozzle pin to the other end of the arcuate slot-in the holder.

Fig. 6 is a view in vertical cross section takenin a plane represented by the line 66 of Fig. 5 and viewed in the direction of the arrows.

Fig. 7 is a view in side elevation of outer end of the removable supply tube.

Referring more particularly to the drawing in which is shown an illustrative. embodiment of .the. present invention, the novel nozzle assembly is shown embodiedvin a.v hand-operated sprayer or spray gun including a-pump: it comprising a barrel or cylinder 11 of metal or other suitable rigid material within which is mounted a cup, plunger or piston 12 (Fig. 2) carried at the inner end.

of a plunger rod 13 reciprocated by a.suitable handle 14. The. plunger rod 13 is held centered and guided in a centrally-disposed opening :in an end cap orclosure 15: removably anchored in the outerend of the barrel 711; by a set screw or the like 16. An aperture'or opening: 17 in the barrel provides an air vent for the entrance of, air into the barrel from where it passes to the front of.

the plunger or piston 12 on theback stroke with the-air compressed and forced into the reservoir or container l8 through aligned openings 19- and 19 and out ofth'e: nozzle assembly 21 on the forward stroke. This; opening. 17 also permits oil to be supplied to the plunger; The. reservoir or container 18 isprovided with a fill opening.

and a threaded capor clo'sure'Zll therefor.

The barrel 11 is enlarged at-its forward end at22 to receive the cup plunger l2atits extremeforward position and to expand anfd'flex this-plunger, which may be of; leather or suitable flexible composition, at each 'stroke-for continued efficiency and to prolong itslife.

At its forward endthe enlarged portion 22 barrel isclosed by 'an end capp23; of substantially frusto conical shapewhich is joined orseamed at 24 to the barrel; by an annular closure'or end wall with thebase of the enlarged portion suitablyafli xed to the reservoir 18 to. form an integral or unitaryassembly, the registering open-l ings 19'and l9 beingv in the enlarged po'rtion22'andii1- the reservoir 18, respectively,

A removable curved siphon or-supply -tube;25;:has-.-one; end 26 projecting downwardly through the openings 19- and 19 into the reservoir;l$,-and with'its upper-or outer [end 27 projecting into thenozzle assembly 2 1j1where'it v is provided with a tip 2 8; pressed onto or suitably aflixec'i thereto. This tip is tapered and closed at itsforward or.

outer end 29 and adjacent thereto is provided with spaced orifices or openings Si -for the passageot the spray solution into the annularsp ace between it and the encompass-. ing nozzle 32. Uponthesupplyor-siphon tube25. and spaced 'rearwardly of its-tip is aflixed the hub 3 v3 -'of. a

supply tube holder orfspider 34 having spaced,;radially'-x arranged arms or projections 35 tensionallyheld 'in'contact with an" annular inturned flange or stop 36 011 the inner end of a cylindrical nozzle holder 37' anchored-in, the end cap 23 and ill-'WlllGll holder the nozzle 32 'is con-, formably received-and movable longitudinally,

A coil spring 38 isanchored-at one-end to'thex-hub 33 of the tube holder 34 and at its other end abutsan annular shoulder:39 in the,bore:40 of thenozzle 32'to hold in operative position the'supply tubeholder 34 and its supply tube 25 against the stop -36 and tourge the nozzle forwardly or-outwardly in the bore. The nozzle holder 37 is locatedin the end cap 23 by meansofan annular flange 41' andretained by the reduced'end 42 of the end cap.

The bore or hollow-interior 40'of the nozzle 32 in ?atented Feb. 2, 1969 charge position shownin Fig. 4 to the closed or shutoff position in Fig. 5.

V 4; and thereby decreases the flow of air about the tip and through the opening 51. 'Ijhis results in a relatively ric mixture or a wet spray suitable for coating surfaces. When the nozzle is rotated or moved to the position shown in Fig. 5, where the tapered end 29 of the tip 28 enters the opening 51 and engages the O-ring 45,'sealing is effected and the spray nozzle is I closed against'leakage or discharge of the spray,

i To move the nozzle 32 in its holder 37, the nozzle is provided with a threaded opening to receive the threaded 1 end of a nozzle shut-off pin46, the shank of which is conformably received and movable in an arcuate slot 47 in'the nozzleholder 37. This provides for opening and closing the spray nozzle by a simple camming action.

When the knurled head 48 of the pin 46 is grasped and moved to the end of the slot 47 to position shown in Figs. 3 and 4, the nozzle 32 is rotated thereby and moved longitudinally and forwardly in itsnozzle holder 37 to its fully extended and open position in which a 'fine, light or atomized spray is ejected for covering a maximum area with the liquid spray.

When-the pin 46' is moved-to the other end of the.

Slot 47, the'nozzle 32 is retracted in ,its' nozzle holder 37 to the position 'showntin Fig. 5 in'which' theannular externalflang'e' 49 of the nozzle forms a stop which abuts the .outer end of the nozzle holder 37. In this position the pointed outer end 29 of the tip 287- enters the opening in the O-ringr45 whereby sealing contact is effected between the tip'28 and the o ring and;

between this O ring and the encompassing inner surface of the nozzle 32 against which this O-ring is held in sealing engagement, 'Thisprovides a most effective seal and shut-off preventing passage of the air and spray solution.

Furthermore, the spray pattern-may be altered'to effect aawet surface coating or residual spray by moving the pin 46" in its slot from the fully open or extended posi- 'tion of the nozzle 32 as shown in Figs. 3 and 4. 7 To facilitate cleaning, the nozzle 32 and the supply ori 'siphon tube 25 are readily removable from the nozzle assembly and from the reservoir or container 18, -Aswill-be apparent from the drawing, unscrewing the pin' 46 permits the operator to withdraw the nozzle 32 and to facilitate such withdrawal or adjustmeritofthe nozzle the annular external flange 49 thereon is preferably knurled. Upon removal of the nozzle, thesupply tube 25 maybe easily and quickly withdrawn for cleaning.

When the nozzle 32 is in' open position for spraying, air under pressure enters the 'reservoir'18 and=exerts pressure against the liquid or spray solution in the reservoir to displace liquid therefrom through the supply or siphon tube 25. This spray solution exits through the apertures 31 in the tip 28. Simultaneously air under pressure from the barrel 11 passes through the bore 40 in the an- From the above disclosure, it will be apparent that the present invention c'omprehends' a novel nozzle assem blyin which the spray nozzle is actuated by a simple 3 operating cam pin and cam slot foreffecting its adjustment between fully opengposition and closed position, and, in which assembly there is provided a supply tube that is readily removed'for cleaning and quickly and easily replaced. 7 7
