Definitions

  • the present invention relates to a spraying device and especially to a novel atomizing sprayer in which a liquid such as an insecticide is atomized and discharged in the form of multiple jets which intersect and project a uniform pattern.
  • An important object and purpose of the present device is to provide in a sprayer of the handoperated type having a cylinder and a pump plunger for projecting a spray of a liquid insecticide, a novel atomizing spray head or cap assembly so constructed and arranged as to atomize and project the spray under high velocity in a novel pattern, whereby to accomplish a greater carry or projection of the liquid particles and a more effective coverage than with prior devices.
  • the present invention further comprehends the provision of a novel spray head or cap assembly including a pair of cap members each having a plurality of spray holes or orifices, the holes or orifices in one member being in aligned or centered relation with those of the other whereby a large volume of spray under high velocity is discharged for each stroke of the piston.
  • Another object of the present invention is the provision of a novel spray head or cap assembly for a sprayer of the reciprocating plunger type, including a pair of outer caps providing a confined liquid chamber therebetween connected to the supply of liquid insecticide and each cap having a plurality of spaced spray holes or apertures opening into the liquid chamber, the holes or apertures being in aligned and centered re-.
  • a further object is the provision of a novel spray head or cap assembly in which the outer cap members are provided with a substantially T-shaped liquid chamber therebetween and each cap member is provided with a series of spaced spray holes or orifices disposed in horizontal alignment whereby the liquid to be dispensed is evenly distributed to each hole or orifice.
  • the present invention further comprehends the provision of a novel spray head or cap assembly provided with a plurality of uniformly spaced discharge orifices so positioned and related as to project a plurality of jets of atomized liquid or fluid and in which these jets intersect, thereby resultinginincreased turbulence and an 2 enlarged spray pattern in which the discharged particles of spray are reduced to a homogeneous state or uniform size.
  • a novel spray head or cap assembly provided with a plurality of uniformly spaced discharge orifices so positioned and related as to project a plurality of jets of atomized liquid or fluid and in which these jets intersect, thereby resultinginincreased turbulence and an 2 enlarged spray pattern in which the discharged particles of spray are reduced to a homogeneous state or uniform size.
  • a further object of the present invention is the provision of a novel construction and assembly which is non-siphoning in operation. Thus liquid entering the chamber provided therefor is prevented from being drawn back into the pump on the return stroke of the plunger and piston.
  • Another object of the present invention is the provision of a novel spray head or cap assembly having an inner cap member or bafile provided with an outwardly and forwardly inclined or flared surface spaced inwardly from a similarly inclined or flared wall portion of the cylinder, and providing a spreader for expanding at the end of each stroke and while the sprayer is at rest the cup packing carried at the forward end of the pump plunger.

  • An opening or aperture 20 in the baflie provides a discharge port for the passage or ejection of air from the cylinder.
  • the spaced flared or inclined surfaces on the cap member l6 and cylinder 2 form an annular chamber for receiving and spreading the flanged part 2
  • the cylinder is closed by a pair of cap members 23 and 24 nested together and spaced forwardly of the inner cap member-16 to provide an air chamber therebetween.
  • the cap member 24 is providedwith a cylindrical flange 25 press-fitted into the cy lindrical end llof the inner cap member [6 and the extreme end thereof is bent over the end of the cylinder, and the outer cap member 23 is nested within-the cap member 24 and provided with a flange 26 which is bent around or spun over the outer flanged and rearwardly bent end of the collar or flange-of the cylinder to interlockthese parts together and whereby to lock the inner cap member IS, the outer cap member 23 and the intermediate cap member 24 in fixed position upon the end of the cylinder. 7
  • the intermediate cap member 24 is preferably indented to provide an approximately T-shaped channel or recess forming with the outer cap member 23 a liquid chamber 21 connected to a liquid supply container or can 28 by a supply tube 29 having its lower inlet end extending downwardly into the container and its upper outlet end connected to an embossment 3
  • a screw cap or closure 32 is suitably soldered or otherwise secured to the forward end of the cylinder 2 for detachably receiving the neck or open end of the container. This cap or closure is provided with an opening whereby to prevent formation of a vacuum in the container.
  • the intermediate cap member 24 is provided with aplurality of preferably uniformly spaced 4 openings or orifices 33 disposed in horizontal alignment in the cross of the T-shaped channel forming the chamber 21, and provided in the outer cap member 23 in alignment with each of these openings or orifices is a discharge opening or orifice 34 of substantially greater dimensions than the openings or or'iflces'33.
  • the outer cap member 23 and the intermediate cap member 24 are each provided with three or a suitable number of similar embossments or indexing means 35 so spaced or arranged that these can members 23 and 24 can only be indexed and nested in one position and that position is with the openings or orifices centered and in horizontal alignment.
  • the recess or channel forming the chamber 2'! is shown as formed in the intermediate cap member 24, it will readily be appreciated that this recess or channel may be formed as an embossment in the outer cap member 23 and the intermediate member may be formed substantially flat.
  • liquid is drawn into'the confined space formed by the recess or channel 21 provided between the outer cap member 23 and the intermediate cap member 24.
  • Air enters the chamber between the inner cap member l6 and the intermediate cap member -24 through the opening-or. port 20 and is discharged through the series or plurality of spaced'and relatively small openings or orifices 33 in the member 24.
  • these spray holes are accurately centered or aligned with the somewhat larger spray holes orapertures 34 in the outer cap member 23 a high velocity of air is created at the outlet or discharge holes, thereby forcing the. atomized liquid out in the form of multiple .jets issuing'at high velocity and which project the spray for a considerably greater distance from the operator than is accomplished with other forms of sprayers.
  • the jets intersect and assure ahig'h degree of atomization. Unlike that in other forms, the blast of air is not impeded by a syphon tube that partially obstructs the air or passage.
