2 Claims.
This invention relates, as indicated, to a spray attachment for fluid containers, but has reference more particularly to an attachment of this character which has been designed especially for use in connection with containers of insecticides, such as DDT.
A primary object of the invention is to provide a spray attachment of the character described, having a novel arrangement of passageways or grooves which is efiective to break up a stream of fluid in a desired manner and to direct the stream in a desired form towards the object or place to be sprayed.
Another object of the invention is to provide a spray attachment of the character described, in which the spray or stream can be accurately controlled, particularly as to length of stream.
A further object of the invention is to provide a spray attachment of the character described, consisting of parts which can be readily assembled and replaced, if necessary; which can be easily disassembled for cleaning purposes, and which are so designed as to permit manufacture thereof in commercially desirable quantities, on standard or conventional screw machines, at fairly low cost.
Other objects and advantages of the invention will be apparent during the course of the following description.
In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,
Fig. 1 is a fragmentary cross-sectional view of a spray attachment embodying the invention, and showing also the manner in which it is secured to a fluid container;
Fig. 2 is a view of a portion of Fig. 1, on an enlarged scale, and with the nozzle insert in longitudinal cross section;
Fig. 3 is a cross-sectional view, taken on the line 3--3 of Fig. 2;
Fig. 4 is a cross-sectional view, taken on the line 4--4 of Fig. 2;
Fig. 5 is an exploded view of the parts shown in Figs. 2, 3 and 4;
Fig. 6 is a fragmentary side elevational view, on an enlarged scale, of a portion of the nozzle insert, and
Fig. 7 is a fragmentary cross-sectional view, on an enlarged scale, taken on the line 'l-J of Fig. 6.
Referring more particularly to the drawings, the spray attachment will be seen to comprise a body member I having a central opening 2, in
which a plunger 3 is mounted for slidable movement reciprocally of said body, the plunger having threadedly secured to its upper end a handle or knob 4 by means of which reciprocal movement of the plunger is effected.
The body member l is counterbored as at 5 for the reception of an 0 ring 6 of synthetic rubber or the like, which ring is held against displacement axially from the body member I by means of a packing cap I, which is threadedly secured to the body member I. The cap 1 serves also as a guide for the plunger 3 during reciprocal movement of the latter. The function of the ring 6 will be presently explained.
The body member I is also counterbored below the opening 2, as at 8, to provide an annular passageway between the wall of the counter-bore and the plunger 3, which passageway communicates with an axial passageway 9 in a nozzle holder IE which is threadedly secured to and extends radially from the body member I of the spray attachment. The nozzle holder I0 is counterbored, as at H, for the reception of a nozzle member 52 having a nozzle or spray opening I3. The nozzle member I2 is threadedly secured to the holder it and has an inner cylindrical wall I4 which terminates at the base of a conical forward wall 55, the apex of which lies at the bottom of the nozzle or spray opening I 3.
Disposed within the nozzle member I2 is a nozzle insert it, which is of square cross-section, having flat sides H, which coact with the cylindrical wall M to provide a plurality of passageways l3 for the fluid which is to be sprayed. The insert it has an extension 59 which is cylindrical for a portion of its length and has a conical end 25! which bears against the conical wall of the nozzle member 10, the angle of the conical end 20 being the same as that of the conical wall 15.
The nozzle insert It has a series of circumferentially-spaced grooves 2| cut therein, which extend tangentially with respect to the cylindrical extension I 51, and which, as shown in Fig. 7, have diverging side walls. These grooves, moreover, extend generally in the direction of the incline of the conical end 20, so that fluid directed through the grooves will be forced toward the nozzle opening 53.
The nozzle insert is normally maintained in the position shown in Figs. 1 and 2 by means of a compression coil spring 22, which is interposed between the nozzle insert and a ball 23, which is seated on the shoulder formed at the junction of the passageway 9 and counterbore II.
Threadedly secured to the body member I, in
axial alignment with the passageway 9 of the latter, is a tube "M, in the lower end of which a valve seat is secured, as by hanging the lower end of the tube over into engagement with the valve seat. A screen 26 is interposed between the valve seat and the flange 21 of the tube. A ball 28 is disposed on the valve seat 25, normally closing the opening in the valve seat.
For the purpose of securing the spray attachment to a fluid container, in this case, a glass bottle B, aninternally-threaded bottle cap member 29 is provided, which is loosely supported by a flange 39 of the body member I, the member 29 normally carrying an annular washer 3|, which acts as a seal when the spray attachment is secured to the fluid container by means of the cap member 29 as shown in Fig. 1.
'When the spray attachment is secured in position on the bottle, as in Fig. 1, an air passage is provided between the atmosphere and the interior of the bottle for the purpose of equalizing the air pressure therebetween. Such air passage includes an annular groove 32 in the lower end of the body member I, a radial passageway 33 in the body member 1 which communicates with the upper end of the groove 92, and an annular space 34 between the cap member 29 and the body member I.
The method of using the aforesaid spray attachment will now be briefly described.
As the handle 4 is pulled upwardly (Fig. 1), the plunger 3 evacuates the space between the plunger and the tube 24, thereby causing the ball 29 to belifted from its seat, and permitting a small quantity of the fluid in the bottle B to be drawn up into this space. Then, as the handle 4 is pushed downwardly, a pressure is set up in this space,'causing the ball 28 to be reseated, and unseating the ball 23. At the same time, the fluid in said space is forced through the annular passageway 8 and the passageway 9, past the ball 23, through the passageways l8, and through the grooves 2| and nozzle opening 13.
Due to the tangential and inclined arrangement of the grooves 21 the stream of fluid is broken up in a desired manner and is directed in a spray of desired form towards the object or place to be sprayed.
The length of the spray or stream can be accurately controlled by the intensity of the pumping action, as contrasted with the action of so-called aerosol bombs, whose action and length of spray is fixed by the pressure within the bomb.
The 0 ring 6 not only acts as a seal or gasket to prevent the fluid from passing upwardly through the cap 1, but also produces a desired wiping or cleaning action on the plunger 3. The screen 26 is effective to prevent foreign matter from finding access from the bottle B into the tube 24.
Most of the metallic parts of th spray attachment are made of a corrosion-resistant metal such as brass or aluminum.
The sprayer has been so designed that the various parts can be readily assembled and replaced, if necessary, and can be easily disassembled for cleaning purposes. Each part is so designed as to permit of manufacture in commerchines, and at fairly low cost.
It is to be understood that the form of my invention, herewith shown and described, is to be taken as a preferred example of the same, and
that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of my invention, or the scope of the subjoined claims.
Having thus described my invention, I claim: 1. A spray attachment of the character described, said attachment comprising a body member adapted for attachment to a fluid container,
a nozzle extending from said body member and said conical wall, whereby an annular chamber is provided having the wall of said cylindricalextension and said cylindrical wall as its inner and outer Walls respectively, said insert having a frusto-conical extension forwardly of the cyline drioal extension whose conical wall bears against said first-named conical wall, said frusto-conical extension terminating at its forward end in an nular flat surface which lies in a plane parallel with the plane of the base of said conical wall, said frusto-conical extension having a multiplicity of circuinferentially-spaced fluid passageway grooves formed therein, said grooves extending substantially tangential to the periphery of said annular flat surface of said frustoconical extension, said grooves having diverging side Walls, whereby foreign particles which become lodged in said grooves are enabled to dislodge themselves. a
2. A spray attachment, as defined in claim 1, in which said grooves have flat bottoms from which the side walls diverge upwardly and outwardly.
