6 iliaims. (Cl. 299-84) This invention relates to mixing nozzles for spraying liquid fertilizers, insecticides and the like by garden hose pressure in the care of gardens and lawns.
In nozzles of the class set forth, the flow of a carrier fluid through a restricted orifice is caused to create suction on a conduit beyond the restriction leading to a supply of insecticide, fertilizer, or the like in liquid concentrated form. It is desirable that the operator have instantaneous control over the suction created, so that mixing will only take place during periods when it is desired, while the carrier fluid is allowed to flow continuously. In certain prior constructions, control over the suction has been exercised by admitting large quaantities of air into the nozzle beyond the restriction or throat, through a port separate from the suction conduit, such port terminating at a point where it can be conveniently covered by a finger when suction on the liquid concentrate is desired. Such port, being relatively large and leading directly to the mixing region, tends to expose the operators finger to contact with the liquid concentrates which in many instances are of poisonous character.
The present invention is directed to a construction in which suction in the liquid concentrate supply conduit is broken by the admission of air directly to such conduit. The invention is further directed to a construction whereby an air port, suitably located on top of the nozzle is provided with a connection to the supply conduit rather than the nozzle to effect the result. The invention is further directed to such an arrangement wherein the air port to be capped by a finger is located at a substantial height above the connection to the supply conduit, whereby the liquid concentrate cannot rise to the port opening and contact the operators finger. The invention further has to do with an economical rugged construction for rigidly affixing a large mouth sheet metal screw jar cover to the body of the nozzle, whereby the nozzle becomes a torque bar in applying the cap to or removing the cap from a jar.
The above and other novel features of the invention will appear more fully hereinafter from the following detailed description when taken in conjunction with the accompanying drawings. It is expressly understood that the drawings are employed for purposes of illustration only and are not designed as a definition of the limits of the invention, reference being had for this purpose to the appended claims.
In the drawings, wherein like reference characters indicate like parts:
Figure 1 is a longitudinal sectional view about twice actual size;
Figure 2 is a side view of the internal sleeve, somewhat further enlarged;
Figure 3 is a longitudinal sectional View of the sleeve, somewhat further enlarged;
Figure 4 is a transverse sectional view taken on the line 44 of Figure 3;
Figure 5 is a top plan view approximately actual size;
' Figure 6 is a sectional view taken on the broken line 15-16 of Figure l; and
Figures 7 and 8 are sectional fragmentary views of modified constructions for forming the annular passage.
Referring to Figure 1, there is shown a body member 10 having at one end an integral internally threaded hose coupling 12 (which may if desired contain an anti-back flow device not shown), a longitudinal bore 14, extending lengthwise therethrough, and a raised horn portion 16 on the top side, curved as at 18 for a finger rest. The under surface of the body member has a planar surface 2% against which a pressed sheet metal can cover 22 rests. The body member is provided with a pair of spaced cylindrical bosses 24 and 25 projecting downwardly from the surface 2% and adapted to project through corresponding apertures in the can cover 22. Washers 28 and 30 are positioned on said bosses, and seated against the cover and are held in place by shear riveting or other heading over the bosses as is shown at 32 and 34. The boss 26 is provided with an integral nipple 35, through which extends a suction port 36, such port leading to the bore 14. The horn portion 16 is provided with an air port 33 extending to the bore at a point opposite the port 36. The cover 22 is adapted to be threaded upon a glass jar 46, as at ll, and the nipple 35 is provided with a length of hose 42 of suflicient length to extend to the bottom of the jar. A coil spring 47 inserted in the end of the hose 42, may act as a screen and space the hose end from the jar bottom.
Within the bore 14 is a bushing or sleeve 44 having a stepped bore 45 therein, such bore increasing in diameter about midway of the length thereof as at 48. The bushing is provided with a single radial port adapted to be aligned with the port 36. Around the exterior of the bushing there is provided an annular shallow groove 52. Such groove might be formed in the bore wall if desired, as indicated at 60 in Figure 7, in which case the bushing would have a smooth external cylindrical surface 62, or the body bore as is shown in Figure 8 may be stepped as at 6 and the bushing exterior stepped as at 66 to provide by inserting the bushing to the depth shown, an annular channel 68.
It will be seen from the foregoing construction, that by reason of the step 43 in the bushing bore 46, water flow through the bore creates suction on the port 56 and if air is not admitted into the bore 38 to relieve the suction, such suction serves to draw fluid from the jar for intermixing with the water passing through the bore 46. The ratio of mixing is reasonably proportional for a wide range of water pressures. The annular passage formed by the groove 52 serves to connect the air port 38 with the break between the port 50 and port 36. If air is allowed to enter the bore 38, the suction on the liquid in the jar is substantially completely eliminated.
When the port 38 is closed by placing a finger on the hole, air is trapped in the port 38, the annular channel 52, and while such air may expand somewhat by the vacuum created to draw fluid from the jar, such volume of air insulates the users finger from contact with the liquid in the jar. As such liquid may be poisonous, it is highly desirable that the operator be thus protected from possible contact therewith, and the annular channel 52 and elongated port 38 serve this purpose. The port 35 and port 50 in efiiect form a continuous passage for the spray fluid in the jar, such passage being broken intermediate its length by the annular channel 52, whereby air is admitted to such passage directly to effectively destroy the vacuum thereon.
The nose of the body portion may be provided with an exterior reduced diameter cylindrical portion 55 to which may be applied a clip 56 having spring fingers 58 extending around the cylindrical portion, such clip having a spray deflector 59 adapted to diffuse the mixture stream emitted from the bushing bore 46.
jar *cover' may be "provided with a small port to v =It willibe seen thatthe-port 36 is relatively largeand free of anyrestriction-arid'aligns'with the port 50 to provide in effect a continuousconduit, such conduit beingbroken only by the annular passage 52. It will also appear that theextended'length of the port 38, added to the length of the annular passage 52 to the single port SOs-located-re'zrrbte-from the port 3-6, provides certain proteetion'a-gainst-concentrate splattering upon or reaching one s finger when placed in capping position over the port 38.
While a single form of the invention with slight modifieation's 'hasbeenrill-ustrated and-described, it is tobe understood that the invention is not limited thereto. 7 As various phanges in the construction and arrangement may be rnade Without departingfrom the spiritof the invention, as will be apparent to those skilled in the art, referencewill be had to the-appended claims for a definition of thejlimits of the invention What-is'claimed'isi '1.
