. 1 Claim. 1
My invention relates to an improved nozzle head which is adapted to produce a cloud of vapor from a stream of liquid. My invention also relates to an improved method in relation to said structure.
An object of my improvement is to produce a cloud of vapor which can'be'most effectively applied in use for extinguishing fire, air conditioning, applying insecticide, spraying vegetation, moistening fuel and various other uses. Another object is the assemblage of nozzle orifices or jets of improved type which coact in producing an exceedingly large volume of fine vapor and which can be easily repaired, adjusted and directed in use. Among further objects is maximum simplicity of construction and increased effectiveness in use.
In the accompanying drawing forming part of this specification, Fig. 1 is a side elevation of a nozzle head which represents one form of my invention;
Fig. 2 is a plan looking down upon the upper end of the nozzle head shown in Fig. 1;
Fig. 3 is a vertical section taken on line 3--3 of Fig. 2;
Fig. 4 is a section taken on the line 4-4 of Fig. 3;
Fig. 5 is a side elevation of one of the orifice jets;
Fig. 6 is a side elevation partly in section of a modified form of one of the orifice jets shown in Fig. 5;
Fig. 7 is a section taken on the line 1-1 of Fig. 6;
Fig. 8 is a view of a detail which is shown partly in section, illustrating graphically, the action of one of the voluted jets of fluid emitted by one of the orifice jets in the nozzle;
Fig. 9 is a diagrammatic view illustrating the voluted vapor produced by my improvement;
Fig. "10 is a detail showing an alternate construction, and
Fig. 11 is an end view of the construction shown in Fig. 10.
In the drawing my improved nozzle head as shown has an internally threaded body A which is adapted to be threadedly coupled to a hose or other duct ID, as shown in Fig. 3. An inner annular shoulder H is provided in the body of the nozzle so that a washer I2 may be interposed to produce a. tight connection between the nozzle head and duct. A fluid delivery chamber I3 is provided between the shoulder and the outer end portion of the nozzle and a plurality of orifice tips B-BB are removably mounted at equal circumferentially spaced distances apart in the delivery end portion of the nozzle.
Each orifice tip has an externally threaded cylindrical body I5 (Fig. 6), into whichfiuid is admitted from the fluid delivery chamber 13 into the jet through a plurality of whirler slots l6, which enter the lower end portion ll of the jet. The whirler slots slant upwardly and circumferentially at an acute angle relative to the axis of the orifice jet so as to direct the fluid laterally and circumferentially in the form of a forward spiral like stream which whirls outwardly through a small orifice H3 in the outer end l9 (Fig. 6) of the jet as illustrated graphically in Fig. 9. As many whirler slots may be employed in a circular series as desired, four slots, for illustration being shown in each jet. Also as many jets may be employed as desired, a circular series of three being shown in the illustration which I found to be highly effective. Each jet is threadedly connected with its body seated in and connected with the chamber I3 in the nozzle and the plurality of orifice jets are arranged with their sets of baffle slots l6 and cooperating orifices l8 coaxially and sufficiently close together so that the several jets of spray produced thereby intermingle in the manner described as follows.
For the purpose of describing the manner in which the several sprays emitted by the cluster of jets cooperate, reference is made to the diagrammatic views shown in Figs. 8 and 9. Fig. 9 illustrates diagrammatically a cluster of jets B-B--B, of a nozzle head, applied in the manner of my improvement in a circular group. The spray produced by each of these jets resembles a whirling voluted stream of vapor as shown in Fig. 8. By assembling these jets in relatively close order in the nozzle head the voluted streams are baffled and comingle by impingement and the resulting mixture D is thereby further reduced to a cloud of refined vapor as illustrated in Fig. 9. The circular impingement of the whirling streams is highly efiective for various purposes to which the invention can be applied.
While three jets are shown with their baflle slots directed to produce whirling action, it is contemplated that any number of jets may be employed, or the slots in the series of tips inclined alternately in reversed direction to further augment the bafiie effect produced by voluted impingement of the sprays to produce a cloud of highly refined vapor.
In Figs. 10 and 11 the whirler slots 2| in the disk-like lower end ll of the jet Bare each in the form of a reverse curve annularly as shown to enhance the whirling mixing action of the fluid.
My improvement is applicable for various uses, such as fire control, air conditioning, cooling systems, atmospheric use in green houses, reducing fluid and powdered fuel, spraying and various other purposes where the presence of vapor is beneficial.
Various modifications of the invention are contemplated within the spirit of the invention and the scope of the following claim.
I claim:
A fog nozzle comprising a nozzle internally screw-threaded to receive at one end a duct sup= plying liquid under pressure, a liquid-delivery chamber in said nozzle connected with said duct,
an annular group of three spray jet th're'adeach of said spray jet units connecting said nozzle chamber with said jet chamber, the axis of each centrally-directed whirler slot being at approximately 120 to its adjacent slot, each of said whirler slots being slanted upwardly and circumferentially at an acute angle relative to the axis of the orifice jet, each of said whirler slots being cut up through the circular, bottom surface of thejetunit on ofij-set, chords, the passage of the liquid through the whirle'r slots, jet chamber and jet orifices being such that sprays are caused to commingle by whirling impingement beyond the delivery end portion of the nozzle to produce highly refined liquid fog.
