Bete, Marion, Mara, assiguor to Beta Fog Nozzie, Ina, Greenfield, Mass, a corporation of Massachusetts Original application Jan. 18, 1961, Ser. No. 83,411, new Patent No. 3,104,063, dated Sept. 17, 1963. Divided and this application July 9, 1963, Ser. No. 293,806 2 filaiins. (Cl. 29--15'7) This is a division of my co-pending application Serial No. 83,411, filed on January 18, 1961, for Spray Nozzle with a Plurality of Continuous Grooves, and now Patent No. 3,104,063, issued September 17, 1963.
This invention relates to the atomization or spraying of liquids and particularly to a simple, inexpensive nozzle system combining a number of small orifices working the liquid flow into a spreading foglike discharge of microdrops uniform in size.
Each orifice produces a spray which fans outwardly from the axis of the nozzle to produce a generally conical distribution of the whole expanding and falling as an even and gently wetting deposit.
FIG. 1 is a side view of the nozzle and spray formation;
FIG. 2 is a face view on enlarged scale of the nozzle with the orifices in a ring;
FIG. 3 is a sectional view further enlarged taken in the plane of line 33 of FIG. 2;
FIGS. 4 and 5 are still further enlarged views taken on lines 4-4 and 55 of FIG. 2;
FIG. 6 is a perspective fragment partially in section showing one aspect of the intersection of grooves A and B;
FIG. 7 is a section taken on the line 77 of FIG. 5; and
FIG. 8 is a section taken on line 8-8 of FIGURE 7.
In the example shown in the drawings, a garden hose has attached at 2 the nozzle 3 with its front piece 4 shaped and formed at front with the atomization and distribution system of this invention.
To attain this the front platelike piece 4 with generally parallel front and rear surfaces 5 and 6 is specially formed with grooves or groove formations A pressed in the front surface 5 and the circular, intersecting, oriflee-forming groove or channel B milled into the rear surface 6.
The front pressed grooves A are circular and of relatively small diameter and generally rectangular in section, and the three grooves are in symmetrical three cornered position around the center C of the nozzle, which is also the center of the rear groove B.
Each groove A is very small in section, about one hundredth of an inch radially, and forms a corresponding axially thin orifice ring 7 at the bottom. These orifice rings or bottom portions 7 of grooves A are intersected by the inner or rear groove B and cut away by the milling of the B grooving as shown to complete at one time all the orifices O.
The groove B is shaped in section to determine the ice surfacing of the orifice and particularly the inner or supply portion 8 thereof, and in the preferred type shown in the drawings the groove is generally rectangular on the outer side 9 and inclined on the other at 10 to become narrower in the direction of the flow and correspondingly influence the lines of flow to direct the discharge outward and avoid an excessive intermixing of the orifice discharges at the center; and the effect is also to contribute to give the even fan-type form without objectionable horns or jets at the outside surfaces.
Thecircular interrelation of the grooves A and B is simple, and also highly variable in determining the character of the spray formation. The angle of the cone will be widened by increase of diameter of groove B and correspondingly a narrow angle hard driving fog may be obtained by decrease in groove B diameter.
In the present example the over-all size is one inch diameter. The orifice size is important and very minute indeed to give maximum dissemmination of the liquid. This in combination with the precision attained in control of the flow gives a most desirable type of spray in which there are a number of contributing formations, each separately predetermined with precision and correspondingly perfecting the final spray.
This high accuracy is also attained in a simple and direct manner correspondingly dependable and inexpensive in requiring only two operations, a stamping and a milling, to ensure the perfect product.
I claim:
1.. The method of forming an atomizing nozzle for liquids comprising forming in the front surface of a platelike piece a number of circular groove formations around spaced axes intersecting said platelike piece with the bottom portions of the groove formations at predetermined dimensions and milling the rear surface of said platelike piece in a circular channel around an axis normal to said platelike piece and to a depth and in a shape to overlap and intersect each of said groove formations and remove the bottom portions of each groove formation at two spaced areas to form a number of tiny atomizing orifices leading from said groove formation.
2. The method of forming an atomizing nozzle as set forth in claim 1 in which said channel is narrowed in depth to direct the liquid discharge at an angle to an axis of the channel.
