The nozzle assembly is easily attachable to a spray gun and a setting ring. rotatable about the hollow shaft. is lockable in different angular positions so that the nozzle head may be quickly adjusted to the selected angular position of the setting ring to control the intensity of the spray jet.
ll Claims, 3 Drawing Figures SPRAY NOZZLE BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to the art of spray nozzles for atomizing liquids having two axially adjustable parts to control the intensity of the spray jet. Specifically. the spray nozzle has a hollow shaft or tube attached to a spray gun with a sleeve nozzle threaded thereon and rotatable within limits set by an adjustable setting ring to vary a gap between the nozzle discharge orifice and the end of the shaft to thereby control the intensity of the spray jet issuing from the orifice. The assembly is especially useful with solvents for removing spots and stains from fabrics.
2. Prior Art Spray guns for spraying solvents on soiled areas of textiles to be cleaned have heretofore required adjustable hand levers and rotatable nozzle heads which are manually manipulated to gradually alter the intensity of the spray jet for obtaining a desired type of jet. This gradual variation or adjustment of the jet is time consuming and is not rapid enough to avoid possible damage to delicate fabrics in spot cleaning operations such as might occur when a high intensity jet is slowly decreased to a non-damaging jet stream. In addition. experimentation is needed to arrive at a jet of the proper intensity for the particular fabric being cleaned and a corresponding loss of cleaning solvent is experienced.
SUMMARY OF THE INVENTION The present invention provides adjustable spray nozzles especially suitable for spraying cleaning solvent on textiles and fabrics to be cleaned wherein the intensity of the jet is quickly and accurately changed to suit the particular fabric being treated. The change from one level of spray intensity to the desired level is effected by rotation of a spray head to different preselected stop points.
The spray nozzles of this invention include a hollow shaft attachable to a spray gun and having a sleeve-like nozzle head rotatably threaded thereon. A stop ring fixed on the shaft has a setting ring rotatable therearound and locked in preselected angular positions relative to the stop ring. The nozzle head is then rotatable to the adjusted angular position of the setting ring and the pitch of the thread connecting the hollow shaft and nozzle head will vary the spacing of the end of the hollow shaft from the nozzle orifice. to thereby vary the intensity of the jet. The setting ring is axially shiftable on the hollow shaft to release it for rotation relative to the stop ring and thereby shift a cam finger to a new position for acting as a stop to limit the rotation of the spray head.
It is then an object of this invention to provide an adjustable nozzle for varying the intensity of a spray jet from one level to another level without time consuming gradual adjustments.
Another object of the invention is to provide an adjustable spray nozzle for spray guns of the type used for spraying cleaning solvents into stained or spotted areas of fabrics which will quickly change the spray intensity to preselected levels so that the fabric being cleaned will not be damaged by the spray jet.
Another object of this invention is to provide an adjustable spray nozzle with a hollow shaft feeding liquid to be sprayed to a nozzle head threaded on the shaft and rotatable against a stop that is angularly adjustable to control the spray intensity.
Another object of the invention is to provide a rotatable and axially shiftable setting ring on a spray tube for selectively positioning a stop member to limit rotation of a spray head at preselected angular displacement positions to rapidly change the intensity of the spray jets from one level to the next desired level.
A further object of this invention is to provide an adjustable spray nozzle assembly easily attachable to spray guns with an axially shiftable and rotatable setting sleeve selectively positioning a stop member to limit rotation of a spray head at preselected angular po sitions for quickly changing the spray jet.
Other and further objects of this invention will become apparent to those skilled in this art from the following detailed description of the annexed sheets of drawings which, by way of a preferred example. illustrate one embodiment of the invention.
AS SHOWN ON THE DRAWINGS FIG. I is a side elevational view of a spray gun for spraying cleaning solvents into fabrics to be cleaned and having an adjustable spray nozzle according to this invention mounted thereon;
FIG. 2 is a longitudinal sectional view through the adjustable spray nozzle of this invention; and
FIG. 3 is a transverse cross sectional view taken generally along the line lII-Ill of FIG. 2.
DESCRIPTION OF THE PREFERRED EMBODIMENT The spray gun I of FIG. I has a handle 2 carrying a finger operated switch button 3 controlling current flow from an .electric conduit 4 to a motor driven piston pump (not shown) in a housing head 5 which suspends a removable supply container or jar 6 which can be filled with solvents to be discharged through the adjustable nozzle assembly 7 of this invention which is removably mounted on the front end of the housing head 5 by means of a cap screw 8. The motor driven pump in the head 5 may be a piston pump which will suck out the contents of the container 6 and propel the same through the outlet orifice of the adjustable nozzle assembly 7.
The nozzle assembly 7, as best shown in FIG. 2, includes a rigid hollow tube or shaft 11 anchored in the housing head by the cap screw 8 and projecting therefrom to feed the solvent from the container 6 through the longitudinal bore 12 thereof to radial outlet openings 13 at the closed outer end of the shaft. These openings discharge into spiral passages or channels 14.
The shaft II has an enlarged diameter band area 15 with external threads 16. A sleeve-like nozzle head 17 envelops the end of the shaft II and has internal threads I8 threaded on the external threads 17 of the shaft. An orifice I9 in the end of the head I7 overlies the end of the shaft and receives liquid from the spiral channels 14 to discharge a spray jet from the nozzle. A seal sleeve 20 between the shaft and nozzle head 17 has a conical groove 20a in the end face thereof which is effective to spread the seal under the pressure of the fluid in the channels 14 so that the fluid cannot leak out of the spray head 17.
A button member 21 is seated around the spray head I7 and locked thereon by a set screw 22 threaded therethrough and having the pointed end seated in a recess in the head l7.
An impact ring 23 disposed around the shaft 11 has an internal axial slot 24 receiving a key 25 to secure the ring 23 against rotation on the shaft. A finger 26 projects radially from the ring 23 as shown in H6. 3 to provide a stop member as more fully hereinafter dc scribed.
The top end face of the impact ring 23 as viewed in FIGS. 2 and 3. has three cireumferentially spaced holes or recesses 27 therein and a setting ring 28 rotatable and axially shiftable on the shaft 11 overlies the impact ring 23 and has one or more pins 29 depending therefrom for selective seating in the recesses 27.
An axially extended cam finger 30 on the setting ring 28 projects into a semiannular groove 31 in the top face of the button 2! and. as shown in FIG. 3, is abutted by the stop member portion 26 of the impact ring 23. As shown. the groove 30 extends about 90 around the periphery of the button 21. It will be seen in FIG. 3 that this stop member 26 limits the rotation of the setting ring 28 to about one full rotation relative to the nonrotatable impact ring 23 because even when the cam finger 30 is lifted out of the semiannular groove 31, the stop member 26 will limit the rotation of the setting ring against the opposite edges of the finger 30. as illustrated in FIG. 3.
The setting ring 28 is axially slidable on the shaft ll to permit a release ofthe pin 29 from a recess and a retation of the ring relative to the ring 23 and for this purpose. a spacing sleeve 32 overlies the ring 28 and is pressed thereagainst by a helical spring 33. The sleeve 32 is keyed to the shaft ll by a key 34. The spring 33 is bottomed on the cap screw 8. Cooperating markings 3S and 35' are provided on the setting ring 28 and on the spacing sleeve 32 to indicate circumferential displacement of the setting ring and thus indicate the jet intensity setting for the nozzle.
In order to preselect and adjust the spray jet issuing from the orifice 19 of the nozzle head l7, the setting ring 28 and the spacing ring 32 are manually depressed against the bias of the spring 33 to lift a pin 29 out of its recess 27. whereupon the setting ring is rotated to positions determined by the markings which, for example. can be marked, soft." medium." or hard." for indicating spray intensity and then releasing the setting ring so that the pin 29 will drop into the selected recess 27. Then. the button 2l is rotated to rotate the spray head 17 therewith to vary the distance between the end of the spray head and the end ofthe shaft, thereby varying the gap of the spiral passages 14 to the nozzle orifice 19. The groove 31, which extends about 90 in the illustrated embodiment, will limit the permissible rotation of the button to the angular displacement permitted by the distance between an end of the groove and the position of the finger 3] in the groove determined by the setting ring.
From the foregoing descriptions it will thus be understood that this invention provides for the quick changing of the setting of a spray nozzle so that it will deliver a spray of the desired character without experimentation.
