.7 Claims; (01. zest-140i)? This-invention relates to spray nozzles utilizing compressed airfor atomization and particularly to such nozzles in which a plurality of supplemental air jets are directed toward the discharged stream of spray material to further atomize it and to form it into a desired pattern.
In the conventional-spray nozzle of this type, as used for spray coating furniture, refrigerator housings, automobile bodies and the like, there'is. an annular air outlet opening around a circular spray material outlet. The purpose of the air from this annular opening is the primary atom- Italso provides a proization' of the material. tective sheath around the material stream which tends to prevent an uncontrolled dispersion of the atomized material by the impingement of supplemental air jets. Prior to beingsubjected to the action of the supplemental air jets the atomized material stream has a forwardly flaring conical form.
It has long been customary'to shape the spray discharge stream into a more serviceable fanpatt'ern'by projecting against opposite sides of the stream forwardly converging air jets. Various other auxiliary air jets of smaller size, and from ports closer to the center orifice than those of the main flattening jets, are used quite generally for improving the atomization, modifying the spray discharge pattern, and assisting in keeping the spray nozzle-clean. The arrangement. of these supplemental jets in spray nozzles commercially available haveuntil recently given satisfactory service with coating materials commonly employed. v
However, the ever increasing rate of consumer demands hasmade improved manufacturingprocedures mandatory. To meet the urgent'need for greater production and lower costs in finishing operations manufacturers are now adopting high-.- er viscosity, heavier bodied materials. These reduce the number of coats required to obtain the.
film thickness desired. It is more difficult to atomize these more viscous materials and, if the. material i's-not well broken up, the resulting film' surface is rough and more time is consumed in sanding and polishing. This additional labor may reduce or nullify the savings attained from the.
application of a fewer number of coats.
The spray nozzle of this invention meets the challenge of these advanced requirements by pro.- viding extremely high atomization with both lacquers and synthetic enamels in a viscosity range of 17 to 32 seconds on a No. 4 Ford cup. At the same time the spraypattern delivered by this spraynozzle is a' fan of exceptional spread, being approximately l5 /g-=incheswide at 6% inches from the surfaceand isaccordi'nglywell adapted terial is evenly distributed throughout the fan for coating largesurfaces at a high speed. 'A minimum of lapping ofithe spray strokes-is necessary as the fan pattern isstraight sided except for well formed tapers at the ends, and as the spray mapat'tern. This; outstandin improvement in performance is derived" principally from the novel disposition of supplementalair jetports on the sides of the center orifice; SO -abOutthe axis from the-location of the main flattening jet ports, and supplementarily from anex-act' positioning of the spray material tipinrelation to the spray nozzle, as hereafter; more fully described and as illustrated in the accompanying drawings in which:
Figure 'lis a front view.- ofa spraynozzle em bodying my=invention;
Figure-2 is a central vertical section taken on 'line 2 z of Figure 1;
"Figure 3 is-a central horizontal section taken on; line 3-3 of Figure I and Figure 4 is a perspective view of the front and side of the'embodiment.
Referring to the drawing, my "invention is shown as applied to a spray nozzle I with a central orifice'2 Intothis orifice'extends aspray material tip-3 as shownin Figure 2. A needle valve 4-is the conventional member for controlling the discharge ofsp'ray material from' tip 3'.
This invention incorporates the discovery that, with spray nozzles of high capacities and fine atomization, cleanliness of the spray nozzle may be better assured by spacing theend of the spray material tip rearwardly of the spray nozzle frontal faceapproximately .003 inch. The general practwo has been to have the end. of the material tip flush: withv thespray nozzle surface. A variation from. this practice; has been-to. have the material tip extend beyond thesurrounding'spray nozzle surface. to increasethe. aspiratingeffect of the air flow. upon the material.
The primary atomizing air travels through space 5 surrounding tip. 3 and. issues; from the.
spray nozzlethrough theannular opening, formed between. the forward endof'tip3' andthe periphcry of orifice 2. This air. provides the initial atomization of the discharged spraymaterial and in conjunction therewith travels forwardly in a gradually expanding conical stream.
From-horns-G and F, pairs of converging fiattening jets are emitted from ports 8, 9', H! and H against theatomized"material stream to shape it intoits final fan pattern.
Between each horn and the center orifice are two ports I2 and I3. These emit clean up air jets in paths parallel or slightly inclined toward the axis of the center orifice. These jets aid in keeping the face of the spray nozzle clean and tend to shield the spray material stream from a piercing impingement by the main flattening jets from the horns. Experience has shown that a single jet of this type in front of each horn may give as satisfactory results as the double jets of this specific embodiment.
On the sides of the center orifice, 90 about its axis from the location of the horns and the clean up jet ports, are oppositely placed sets of three ports M and [5. These ports are disposed in a well-forming inverted frustro-conical surface flaring outwardly from theface portion of the spray nozzle surrounding the center orifice. The axes of the ports areperpendicular to the conical surface, or, as possibly more correctly defined, are perpendicular to planes tangent to the conical surface at points of intersection of the axes with the conical surface. The frustro-conical surface is on the inner side of a ridge which is non-continuous on the sides adjacent the horns B and l. The two segments l6 and I! of the ridge form horns of miniature size compared to the horns 6 and i, but which are proportionately wider circumferentially of the nozzle. In regard to both pairs of horns the inwardly facing surfaces in which the horn air ports are located are conical in contour and the port axes are perpendicular to the conical surfaces.
Due to the raised location of the ports l4 and I5 they are brought into closer proximity to the axis of the central orifice. This feature in association with the symmetrical encircling relation of the port surface area to said axis results in a special concentration of the power of the jets emitted from these portsupon the central stream of material and air.
Each set of three ports is positioned to project three air jets along converging axe meeting at a common point on the axis of the center orifice. The power and action of these merging jets so agitate and form the primarily atomized stream of spray material that, with the subsequent impingement of the main flattening jets from the horn ports, 8, 9, i and II, the stream of material becomes thoroughly atomized and evenly distributed throughout an exceptionally wide fan pattern.
My copending application Ser. No. 184,538, filed September 13, 1950, similarly entitledSpray Nozzle, relates to a specific form of the basic feature of striking the central stream near its source on opposite sides witha plurality of non merging jets. Instead of having the jets directed along converging paths as in this application the jets of this copending application are directed along parallel paths.
In one form of my invention with which typically excellent results may be obtained, the more forward port (8 and 40) in each horn is .052 of an inch in diameter and is directed at an angle of 65 toward the axis of the center stream; and the more rearward port (9 and H) of each horn has a diameter of .070 of an inch and is directed at an angle of 58 toward the center stream axis.
The inner clean up jets in this preferred form issue from ports I3 which are .024 of an inch in diameter and direct air jets toward the center axis at an angle of while the outer clean up jet ports 12 are .0225 of an inch in diameter and 4 their jet paths are angled at 10 to the stream axis.
The atomizing jets emitted from the sets [4 and 15 of three ports on each side, 90 about the axis from the horns, strike the center axis at an angle of The centers of the ports lie in an arc with a radius of .125 of aninch from the axis of the center orifice. The individual ports on each side are .054 inch apart from center to center, and each is .025 of an inch in diameter.
In another form of my invention with which very good results may be secured the more forward horn 'port is '.070 of an inch in diameter and directed in a path angled toward the center axis at 65, while the more rearward horn port is .0685 of an inch in diameter and is angled at This is at variance with the horn port arrangement of the first form described in that the more forward port is larger instead of smaller than the more rearward port and the angles to the center axis of the emitted jets difier. It may be noted that the smaller of the more rearward jets meets the central stream at a slightly more direct angle. This is inclined to compensate for the reduction in size.
The three sets of atomizing ports (14 and i5) at opposite sides of the center orifice in the second form all direct air jets along paths angled at 30to the axis of the center orifice, the
two outer ports of each set being .026 of an inch in diameter andthe inner one .038 of an inch.
They are all .107 of an inch from the center oricific embodiment but may be utilized with various sizes, positions, and angularity of supplemental air jets. 7
