Description

Aug.23, 1938. H. E. NORTON I SPRAY NOZZLE Filed May 9, 19:55
INVENTORY Horzan ATTO R N EY Patented Aug. 23, 1938 UNITED STATES PATENT OFFICE 8 Claims.
The object of this invention is to produce a spray nozzle that will convert liquid into a very fine spray or mist.
Another object of the invention is to produce a spray nozzle that will produce a very fine spray distributed over a considerable angle in a comparatively thin layer.
Another object of the invention is to provide a spray nozzle that will produce a very fine spray from liquid forced through it under high pressure.
Another object of the invention is to produce a spray nozzle that will produce a fine spray, by forcing the liquid through a narrow slot in a curved plate at the end of the nozzle, under high pressure. I
Another object of the invention is to combine in the nozzle a curved plate having a narrow slot therein at the end of the nozzle, with a baffle plate inside of the nozzle having openings therein that give to the liquid a tangential or swirling motion before it reaches the exit opening.
These and other objects of the invention will be illustrated in the drawing, described in the 25, specification, and pointed out in theclaims at the end thereof.
In the drawing:
Figure 1 is a side elevation of the spray nozzle.
Figure 2 is an end elevation of the spray nozzle, 30.;locking at it from the left of Figure 1.
Figure 3 shows a cross section of the nozzle, the section being taken on the line 3r3$ of Figure 1.
Figure 4 is an elevation of the bafile plate shown in Figure 3.
35 Figure 5 is a front elevation of a modified form of the spray nozzle.
In the drawing like reference numerals indicate like parts.
In the drawing reference numeral l indicate 40 a tube, on which is mounted a housing or hub 2.
This housing is threaded on the outside as indicated at 3 and on the end is provided with a seat 4, on which rests the twirling or baflle plate 5. On this baflie plate rests a washer or gasket 6.
45 On top of this rests a concave disc I having a long, narrow slot 8 therein. The parts are held together by a cap 9, which is threaded on to the housing and has an annular shoulder l0 thereon, which engages the rim or seat provided therefor 50 in the concave disc I.
The twirling plate 5 is stationary and has two holes I I and I2 cut tangentially near the periphery thereof. This plate divides the end of the spray nozzle into two chambers I3 and. I4. The
55 twirling plate 5 causes the liquid as it flows from the rear chamber l3 into the forward chamber I 4 to take on a swirling motion. The twirling plate is also provided with a central opening l5 through which some of the liquid goes direct. The tangential openings II and I2 form a whirl- 5 pool in the forward chamber I4, and the central opening l5 sends a jet into the forward chamber that tends to break up the whirlpool. These openings cause the liquid to reach the slot 8 with cross currents that interfere with or pre- 10 2 vent the liquid from being projected through the slot in a solid mass, and instead, cause it to be spread out and broken up into an extremely fine spray or mist within a short distance of the nozzle, and which, under high pressure of from 200 15.
to 500 pounds, is projected from the nozzle to an ample distance for effective spraying of fruit trees.
The mist emerges from the nozzle in a fanshaped stream that tapers anywhere from 45 to 20 cut with a mill having a width of about a thirtysecond of an inch. The tangential holes H and I2 are drilled with a bevel of about sixty degrees, and the central hole I5 is drilled substantially perpendicular to the plate.
The plate 5 may be formed with as many as six tangential holes, similar to the holes II and I2, or with any intermediate number.
In Figure 5 I have shown a modification of the plate I, in which the plate I with the slot 8 is replaced by a similar concave plate with a series of five small holes l6, l6 therein.
