Description

o. w, KROMER SPRAY NOZZLE lled June l5, 1953 IN V EN TOR. @Wm www United States Patent O SPRAY NOZZLE Orlando W. Krorner, Minneapolis, Minn. Application June 15, 1953, Serial No. 361,643 12 Claims. (Cl. 299-121) My invention relates to spraying nozzles and has for its primary objective the provision of a nozzle which willthrow a substantially uniform spray in a fan shape pattern of fixed and unprecedented width.
A still further object of my invention is the provision of a spray nozzle which is more efficient than any single spray nozzle or combination of spray nozzles heretofore produced, which cannot get out of adjustment, and which, by virtue of its having a single large opening, cannot become clogged.
A still further object of my invention is the provision of a device of the class above described which is extremely light in weight, which has a minimum of parts, and which is extremely inexpensive to produce.
A still further object of my invention is the provision of a spray nozzle which is rugged in construction and which will maintain its accuracy for a longer period of time.
The above and still further objects of my invention will become apparent from the following detailed specification, appended claims, and attached drawings.
Referring to the drawings, wherein like characters indicate like parts throughout the several views:
Fig. 1 is a view in rear elevation of my novel sprayer in use;
Fig. 2 is an enlarged view in side elevation;
Fig. 3 is a View in rear elevation on the same scale as Fig. 2,'
Fig. 4 is a View partly in section and partly in end elevation as seen from the line 4 4 of Fig. 2; and
Fig. 5 is a fragmentary view in bottom elevation as seen from the line 5 5 of Fig. 3.
Referring with greater particularity to the drawings, the numeral 1 indicates in its entirety a main body or head having therein an axial bore 2, to the rear end portion of which a iluid` conduit or pipe 3 is adapted to be received. The reduced forward end 4 of the bore 2 provides a forwardly opening jet-producing outlet. Body 1, as shown, is preferably formed from brass, cast iron, or steel bar stock, and has a forwardly extended neck 5 at its upper portion. As shown particularly by Figs. 3 and 4, the neck 5 extends radially outwardly from the bore opening 4 and is of less than 180 degrees in circumferential extent. For a purpose which will hereinafter become apparent, the neck 5 has arcuate converging undersurfaces 6 which intersect the upper end portion of the bore 4 on opposite sides of and in spaced relation to a line drawn vertically therethrough.
A circular spreader or impact plate 7 is detachably secured to the forward surface 8 of the neck 5 by means of headed bolts 9, and is generally concentrically disposed with respect to the bore 4. The spreader surface 10 of the spreader plate 7 is smooth and preferably polished. Furthermore, this surface 10 is at right angles to the axis of the bore 4 whereby to produce a downwardly and laterally outwardly opening spray passage 11, the upper extent of which is defined by the arcuate undersurfaces 6 of the neck 5, and hence said passage 11 has a circumice ferential extent greater than degrees but less than 360 degrees.
In order that a spray of uniform density from end to end may be created, I provide a lip 12 which projects forwardly from the body 1 into the spray passage 11. As shown, the lip 12 has a surface 13 which slopes forwardly and downwardly from the undersurfaces 6 of the neck 5 toward the spreader plate 7. In practice, I have found that most eicient results are achieved by sloping of the surface 13 at a range of angles from between 10 and 16 degrees, specifically at 13 degrees with respect to the plane of the adjacent surface 10 of the spreader plate 7. As shown, the bore 4 opens through the surface 13, the surface 13 terminating in a point 14 below the bore 4 and in closely spaced relation to the spreader plate 7. The entire area of the surface 13 above the bottom 15 of the bore 4 is in the same plane. However, the pointed lower end portion of said lip 12 below'the bore 4 is substantially parallel to the surface 10 of the spreader plate 7, as indicated at 16. Note also that the undersurfaces 17 of the lip 12 converge in straight lines defining a segment of less than 180 degrees.
In operation, fluid under pressure entering the main body 1 through the pipe 3 is exited in a jet through the bore 4. This jet of uid is forced against the smooth surface 10 of the impact or spreader plate 7 with considerable force. The iluid tends to be spread uniformly in all directions. However, the neck 5 and particularly the arcuate undersurfaces 6 create the upper limits of the fanshape spray pattern X, illustrated in Fig. 1. Note particularly, by reference to Figs. 2 and 5, that the upwardly and rearwardly sloping surface 13 of the lip 12 creates a space between the lip 12 and the surface 10 of the spreader plate 7 which increases in width progressively from the parallel surface 16 thereof to the undersurfaces 6 of the neck 5. By this means, the least amount of the spray-producing uid, entering the head 1 from the conduit 3, is allowed to pass between the closely spaced substantially parallel surfaces 10 and 16 to the area of the ground immediately thereblow; and an increasingly greater amount of fluid is utilized as the lateral distance from the head 1 increases on opposite sides. Note that the outermost limits of the spray X, identified by the numeral 18 in Fig. 1, is formed by the widest area between the surfaces 10 and 13, namely the juncture of the surface 13 with the undersurface 6. Note also, as shown in Fig. 2, that the arcuate undersurfaces 6 likewise extend angularly upwardly in the direction of the spreader plate 7 for increased eilciency.
My invention has been thoroughly tested and found to be completely satisfactory for the accomplishment of the above objects, and while I have disclosed a preferred embodiment thereof, I wish it to be understood that same is capable of modification without departure from the scope of the appended claims.
