sprayersa An object ot our invention is to provide a simple and eiicient portable liquid sprayer, having means for detachably connecting` the saine to commercial liquid storage containers ot variousy sizes and capacities, and wherein the parts 01' thesprayer are so arranged and proportioned that the intakeV olf the same will always extend to the proper depth into containers of ditferentvdepths toassure the complete removal ot the entire contents thereof.
A more specific object of the invention is to provide a device ot the character indi* cat-ed comprising a pump bari-eh a piston working in the pump barrel and a hollow piston rod having oneend connected to the piston and the other end terminating in a spraying nozzle, together with means comprising a stopper acting member ot varying e diameter in cross-section surrounding said barrel and adapted to be inserted in the dit- 'l'erentfsiZ-ed necks ot containers ot varying sizes for holding the pump barrel in proper position within the container. n
ln the drawingsforming a part of this specilication, Figure 1 is a longitudinal ver* tical sectional view of a sprayer embodying our improvements, showing the same 'in position within a container also in section, and Figure 2 is a longitudinal sectional view through the spraying nozzle.
ln said drawings, 10 indicates a .sheet metal container of well known construction provided with a screw threaded neck 111 adapted to receive the usual screw threaded closure cap.y
The sprayer comprises a barrel 112 having secured therein at its lower end a reducing member 13 by soldering the same thereto or attaching the same in any other well known manner.
A hollow reciprocating piston rod 16 is slidably mounted within the barrel 112 and has connected thereto at its lower end by soldering the same thereto or securing the same in any other well known manner, a connecting lit-ting 17 having a reduced screw threaded lower end 18 adapted to receive the piston member 19. The piston member 19 consists o a pair of cup-shaped washers 2O and 21 held in place against the shoulder 22 by a nut 23 screwed on to the threaded end of the iitting 17. l`he litting 17 is provided with a central bore 24 to provide coinniunication between the inner portion of the hollow piston r-od 16 and tlreinterior of the barrel 12. A valve seat 25 is formed at the upper end ont the bore ol the litting 17 and a ball check valve therewith. The barrel 12 is also provided with a check valve comprising a ball 2? ada-ptedto o o-act with the seat 28 :formed at the upper end ot the tube 114.v Y i A stopper member 129 is shown ot tapering or trusto-conical 'form and is adjustably connected Vith the barrel 112 ot the sprayer. As sho\vn,tlie barrel 112 has its upper Iend provided with exterior steep pitch screw threads 150 and has secured to the upper end lthereot a vcap having a downwardly pro gecting annular flange 136 en y I @aging with the uppermost thread of the threads and vbia-.vinga guide opening` 151 therein receiving the upper end or" the piston rod 116.
The stopper member 129 comprises an inner threaded nut member 152 engaging with the threads 150 on the barrel 1127 and an outer conical sleeve member 153 secured to the nut 152 by solder or any' other well known means. Securedto the upper vend of the nut 152 and sleeve 153 is a disc 154 having laterally proj ect-ing wings 155 adapted to serve as linger rests. Y
The upper end portion 39 oi the hollow piston extends at right angles to the major portion thereof and is connecter thereto by the curved portion 48. The outer end of the tubular portion 39 is provided with a spraying nozzle or tip 40.' The tip 40 as clearly shown on Figure 2 is provided with interior screw threads 41 in threaded connection with a litting 42 receiving the end ot thetube 39 and being secured thereto by solder or any other well known means. A plug 43 is re'- ceived within the cap 40, the former being provided with threads engaging with the threads 41 ot' the cap 40. The plug 43 is provided with oppositeiy locatedV diagonal grooves 44 forming ports to convey the liquid from the tube 39 to the front end of the cap to thereby produce a whirling action ot the fluid as it passes through the tip. The plug 43 is also provided with a rearwardly project-ing cylindrical post 45 loosely received within the end ot the tube 39 to there- 26 is adapted to co-oper-` Cai by provide an annular recess 46 to direct the liquid to the inner ends of the ports 44. rllhe outer end of the cap 40 is provided with a small perforation 47 through which the liquid is sprayed; p y
In'operation the device is adapted to be inserted in the vessel110, the conical stopper 129 being fitted within the mouth 132 of the neck 111 of said receptacle. Should the 'lower end of the tube 114 not extend to the proper depth-into the vessel to assure the removal of the entire contents', the barrel 112 may be rotated within the nut`152 thus adjusting the sleevev 'downwardly toward the bottom of the vessel; lt will be evident that due to the conical construction of the stopper 129,
the Vsaine is adapted to 4lit the various sizes of mouths of different capacityV containers, and that due to the screw threaded adgustment provided between the stopper 129 and Y the barrel 112, the barrel 112 together with the tube 114. may be adjusted to correspond to the varying depth of vessels of different capacity and size. lllhe finger rests 155 are then engaged by the operator and the piston 16 is i'eciprocated. Upon upward movement of the piston rod 16, liquid will be drawn upwardly through the tube 114 into the barrel 112 of the sprayer. During this upward movement of the piston it is obvious that the valve 26 will be closed while the valve 28 will be open to admit, the fluid. Upon the nent downward stroke of the piston rod 16, the valve 28 will be closed and the valve 2G will be forced open due to the upward pressure yof the liquid, andthe liquid forced through the hollow piston rod 16. During successive reciprocations of the piston rod 16, the liquid will be forced through the hollow piston rod past the plug 43, a whirling motion being imparted to the same by passage through the ports 44, and will finally be sprayed through the small opening' 47 in the cap 40.
Vie have herein shown and described what we now consider the preferred manner of carrying out the invention, but the saine is by way of description only, and not by way of limitation. All changes and modifications are contemplated that come within the scope of the claims appended hereto.
barrel and terminating with a spray nozzle,
and the said piston rod being formed outwardly of the pump barrel, to provide a hand grasp for reciprocation; intake and outlet valves associated with said pump barrel and piston; a plug` adjustably threaded 4on the exterior of said pump barrela said plug being exteriorly formed to adapt it for co-opeiation with the discharge openings of varying diameters of the containers; and finger nieces located adjacent said plug and extending' laterally of the sprayer whereby the spray-er may be held in proper position in the container by said finger pieces by one hand of the operator and the piston and pisn ton rod operated by the other hand of the operator.
2. In a spraying device, the combination with a pump barrel adapted to be inserted into containers having various sized orifices, and of various capacities; of means for supporting said barrel in a container, said supporting means having a graduated 4contour whereby orifices of different sizes may be snugly engaged; and means connecting said barrel and supporting means whereby rotation of said barrel relative to said supporting means effects longitudinal movement of said barrel with respect to said container for ati- ]'usting the barrel in containers of varying capacity while in operativo position.
