SPRAY NOZZLE Filed Oct. 5, 1959 INVENTOR. DIV/IV E. HANSON United States Patent 3,066,870 SPRAY NGZZLE Edwin E. Hanson, 239 Garfield Road, E., Aurora, Ohio Filed Oct. 5, 1959, Ser. No. 844,401 1 Claim. (Cl. 239-113) This invention relates to a new and improved spray nozzle especially designed for use in fluid systems and the like.
A primary object of the present invention is the provision of a new and improved spray nozzle especially designed for use in a fluid system and the like, wherein it is desirable to provide a normally directed fluid spray from said nozzle, and further wherein said nozzle may be readily adjustable to initiate still another flow condition therethrough and thereby provide for the discharge of an accumulation of foreign matter from said system.
Another object of the present invention is the provision of a new and improved spray nozzle especially designed for use in a fluid system or the like, and wherein said nozzle includes a part adapted to be connected in communication with said system, and a second part movably attached to the aforesaid communicating part, cooperating therewith in a first position to provide a normally directed fluid spray from said nozzle, said movable part being further adjustable to a second position to initiate still another flow condition through said nozzle to thereby provide for the discharge of an accumulation of foreign matter or the like from said system.
Still another object of the present invention is the provision of a new and improved spray nozzle, as referred to in the last preceding paragraph, and wherein said adjustable part, in its first position, is in the path of fluid flow from said nozzle, thus cooperating with said fixed part to provide a predetermined directional fluid spray from said nozzle, and further movable relative to said fixed part to said second position to thereby initiate another flow condition through said nozzle and provide for the discharge of an accumulation of foreign matter from said system.
Other objects and advantages of the spray nozzle of the present invention will be realized by one skilled in the art to which it pertains, and upon reference to the following description of a preferred embodiment thereof and which is illustrated in the accompanying drawings forming a part of this specification, and wherein;
FIG. 1 is a plan view of a spray nozzle embodying my invention;
FIG. 2 is a side elevational view of the spray nozzle shown partly in section to thus indicate the internal construction thereof, and further with the movable nozzle part being shown in its second or raised position in dotted lines;
FIG. 3 is a front elevational view with the movable part of the spray nozzle in the aforesaid raised position therefore; and
FIG. 4 is a front elevational view of the instant spray nozzle with the movable nozzle part thereof in its normal fluid impinging position forwardly of the fixed nozzle part.
Referring now to the drawings throughout which like elements are designated by the same reference numeral, the spray nozzle of the present invention, as is indicated in its entirety by the reference numeral 10, is composed basically of two parts, one of said parts being referred to herein as the fixed nozzle part, as is identified by the reference numeral 11, and the other of said parts being hereinafter referred to as the movable nozzle part, and which is herein designated by the reference numeral 12.
The fixed nozzle part 11 includes a nozzle body 14, being preferably tubular or conduit-like in configuration and defining a fluid passageway or channel 15 centrally therethrough. One end of the nozzle body (not herein 3,066,870 Patented Dec. 4, 1962 shown) is preferably threaded so as to enable its being readily insertable into the wall of a flow pipe in a fluid system, or the like, the latter thus communicating with said passageway and hence providing a fluid flow into and through said nozzle body. The opposite end of the aforementioned nozzle body 14, as best seen in FIG. 2, is preferably integrally formed with an annular flange as is indicated at 16, said flange defining an opening or outlet orifice 17 for said nozzle passageway 15 through which a fluid flow is discharged from said nozzle part 11.
As previously mentioned, the spray nozzle of the present invention is normally operable to provide a directional fluid spray, and to accomplish this, the aforesaid movable nozzle part 12 is intended to be disposed forwardly of, and/ or downstream from the outlet orifice or opening 17 of passageway 15 and in an impinging relation with the fluid flow exiting from said orifice. For this purpose, the nozzle part 12 is seen to comprise a central portion 13 substantially cylindrical in configuration being integrally formed at its one end with a fluid diverter head 19, the latter also being somewhat cylindrical in configuration, but preferably somewhat larger in diameter than the aforesaid central nozzle part 18, the reason for which will be hereinafter apparent.
The nozzle part 12 is preferably pivotally attached to the fixed nozzle part 11 in such manner as to normally locate the aforesaid diverter head 19 forwardly of the nozzle orifice or opening 17 and for this purpose, said diverter head part is preferably integrally formed with a pivot arm 21 which, as is best seen in FIGS. 1 and 2, includes an upstanding arm portion 21a integrally attached at its uppermost end to one end of arm portion 21b, the latter extending substantially longitudinally of the aforesaid nozzle part 12. A yoke member 23 is provided with an annulus part 24, and as is best seen in FIG. 2, the nozzle body 14 is placed within said annulus part, the latter being preferably disposed at the forward or discharge end thereof, and having an annular recess 25 which readily accommodates the aforementioned body flange 16. Said yoke member as thus located is preferably,
secured to the nozzle body 14 by any suitable fastening means, not herein shown. The yoke member 23 is also provided with a pair of hinge arms 27, which extend outwardly from the annulus part 24 thereof, and in substantial parallel spaced relation. The pivot arm portion 21b on the nozzle part 12 is extendable between the hinge arms 27 and pivotally anchored thereto adjacent its free end by means of hinge pin 28.
In this manner, the nozzle part 12 is swingably attached to the nozzle part 11, said connection being such that said nozzle part 12 may be disposed forwardly of the nozzle part 11 in a position such as is shown in FIG. 2, wherein said nozzle part 12 is in substantial longitudinal prolongation of the aforesaid nozzle part 11 to thus locate the diverter head part 19 forwardly of the nozzle outlet orifice or opening 17 and hence in an impinging relation to the fluid flow passing therethrough.
With the nozzle part 12 disposed in the position just described, means are provided to retain the diverter head part 19 in predetermined spaced relation to the nozzle orifice in an impinging relation to the fluid exiting therefrom to thus form and permit a fluid spray to pass therebetween; said means, in addition, functioning to direct the discharging fluid spray in a downward direction from the aforesaid orifice, as viewed in FIG. 2. To accomplish this, said means comprises an impervious wall as is indicated by the reference numeral 30 and which is preferably integrally formed on the front face of the nozzle body 14, said wall projecting substantially longitudinally outwardly therefrom being preferably arcuate in configuration, and extending at least 180 around the upper portion of said outlet orifice 17.
With the nozzle part 12 moved to its position forwardly of the outlet orifice 17 in nOZZle part 11, and in substantial longitudinal prolongation with the latter, the wall 30 is intended to be of such dimension as to engage with the adjoining fluid diverting wall of the diverter head part 19, thereby spacing the same from the aforesaid outlet orifice 1'7 and thus defining a downwardly facing exit passageway 31 between said head part and orifice.
With this construction, it will now be realized that as a fluid flow passes outwardly through the aforesaid orifice 17, it travels across the passageway 31 longitudinally of the said nozzle parts wherein it impinges upon the fluid diverting wall of the diverter head part 19. And, with the arcuate wall 30 engaging with the fluid diverting wall of said diverter head part, said flow is confined therebetween and directed thereby in a downward direction to thus exit from the passageway 31 as a fluid spray, the latter being indicated in FIGS. 2 and 4 by the reference character S.
If so desired, the aforementioned fluid diverting wall of the diverter part 19 may be constructed of a suitable pliable material such as a leather fabric or the like, preferably in the form of a flat washer, as is identified in the disclosed embodiment by the reference numeral 34. Said washer is placed over and securely fastened to the face 35 of the diverter head part 19 by means of suitable fastening means 36.
With this construction the forward projecting edge of the Wall 30 engages with the fabricated washer element to thus provide a substantial fluid tight seal therebetween to thereby assure that the said fluid flow is directed and thereby diverted in a downward direction and outwardly through the aforesaid exit passageway 31. When using the aforesaid pliable material to define the fluid diverter wall 34, the diverter head part 19 is preferably of such dimension that with the nOZzle part 12 in its FIG. 2 position, said wall is disposed forwardly of and in spaced relation to the outlet orifice 17 in the nozzle part 11, and as to extend substantially transversely thereacross. The diameter of the diverter head part 19 and also of the aforesaid diverter wall 34 are preferably greater than the diameter of said outlet orifice 17 so that substantially all of the fluid passing through the latter will impinge upon said wall.
As is well known to the artisan, the fluid stream traveling through the nozzle passageway may be of sufficient magnitude as to tend to swing the nozzle part 12 upwardly about its pivotal connection 28 being thus effective to move said diverter wall from its fluid impinging relation therewith and to terminate the fluid spray S.
To prevent this from occurring, the movable nozzle part 12 is preferably integrally formed with a weighted part as is identified by the reference character 38, the latter being somewhat bulbous or mallet-like in configuration and integrally formed on the end of the aforementioned cylindrical part 18 of said nozzle part 12 opposite the diverter head part 19.
With this structure, it will be apparent that with the nozzle part 12 in its FIG. 2 position, the weighted part 38 thereof, acting through the latter, which in effect takes on the form of a compound lever being pivoted at 28 to the nozzle part 11 and engaged with the aforesaid wall 30 intermediate the said weighted end 38 and said pivotal connection, provides a suificient counterclockwise moment, as viewed in FIG. 2, to resist any tendency of said nozzle part 12 to swing upwardly as a result of the force exerted by the impinging fluid stream.
As is also previously mentioned, it oftentimes is desirable to provide for the discharge of an accumulation of foreign matter from within the fluid system connecting with the instant spray nozzle 10.
To accomplish this, the nozzle part 12 may be swung upwardly, as viewed in FIG. 2, about its pivotal connection 28 to carry the fluid diverting wall 34 away from its fluid impinging position, and thus completely expose the outlet orifice 17 of the nozzle part 11. In this manner, a substantially free fluid stream is permitted to transgress the nozzle 15 and thence to exit through the orifice 17 therefore. And, as a result of the aforesaid free flow being thus established, any accumulation of foreign matter and the like, is swept up by said stream and also carried through the aforesaid passageway 15 and out of said orifice.
In this manner therefore, the flow pipes of the fluid system communicating with the spray nozzle of the present invention, may be periodically cleansed.
Having thus described the aforesaid nozzle embodiment it is understood that the same is susceptible to various changes, modifications and arrangements of parts without departing from the inventive concepts thereof as are defined in the claim.
What is claimed is:
A spray nozle, comprising a body member having a passageway therethrough with its outlet opening in the front end face of the body member, said body member being connectable to a source of liquid for the flow thereof through said passageway, the front end face of the body member being substantially at right angles to the direction of liquid flow as it emerges from said outlet opening, and a liquid flow diverter member having a liquid flow-diverting face for cooperation with the front end face or" said body member, said diverting member being pivotally mounted for vertical swinging movement to thereby position the flow-diverting face thereof in front of and generally parallel to the front end face of the body member for flow-diverting purposes or to position said flow-diverting face in an upward out-of-the-way position, said diverter member being weighted so that its flow-diverting face remains in front of the front end face of the body member until the diverter member is manually swung upwardly to locate its flow-diverting face in its out-of-theway position, and one of said members being provided on the face thereof with an arcuate rib which engages the face of the other member when the flow-diverting face of the diverter member is in flow-diverting position and which rib is located just above the outlet opening in the front end face of the body member for downward direction of the liquid which emerges from the outlet opening.
