Other objects reside in details of construction and in novel arrangements of parts, which will appear more fully in the course of the following description.

In the drawing, like referencecharacters designate similar parts in the several views.

Figure 1 is a partly sectional elevation of an assembly including an embodiment of my invention.

Figure 2 is a magnied face View of such embodiment.

Figure 3 is a section taken on the line 3 3 of Figure 2.

Referring more in detail to the drawing, the reference character 4 generally designates a hollow body member having a threadyed entrance 5 at `one end and a threaded eX- tension 6 at the other end. A conduit 7, connecting with a source of oil (not shown) preferably under pressure, is screwed into F the entrance 5. The hollow body provides a chamber 8 that receives the contents of the conduit 7 and transmits same to a plurality of small passages 9 that extend through the body 4 and extension 6. The body has a hexagonal surface 10 for ease in assembling.

A disk 11 is placed at the end of the-eX- tension 6. The disk has a circular channel 12 disposed opposite the open ends of the pas- "v sages 9. The disk 11 also has a circular channel 13 concentric with the channel 12. The two channels are connected by means of transverse `grooves 14. Y

Moreover, the present invention may be used for atoinizing or spraying other liquids without departing from the spirit and scope of the invention.

l/Vhat I claim and desire to secure by Letters Patent is l. In an oilburner, a nozzle for the discharge of oil, having outer and inner ann'ular spaces in a face interior-ly of the nozzle, the nozzle having a passage for supplying oil to the outer space, said face having strainer grooves connecting the spaces, the nozzle having a discharge aperture and grooves tangent to the aperture in said face and coininunicating with the inner space 'to conduct oil entered into the outer space and thru the strainer grooves, to the discharge aperture.

2.v In an oil burner, a nozzle for the dis-- charge of oil, having outer and inner annular spaces in a face interiorly of the nozzle, the nozzle having a passage for supplying oil to the outer space, said face having strainer grooves connecting the spaces, the nozzle having a discharge aperture and grooves in said face connecting the inner space with said aperture, to conduct oil passing` from the outer space thru the strainer grooves, to the discharge aperture.

3. In an oil burner, a nozzle `for the discharge of an oil spray, comprising a disk having a discharge aperture, a surface thereof,having a groove tangent to and connected with the aperture and having a set of strainerl grooves in the forni of open channels connected with the first-mentioned groove and cutinto said surface of the disk, and arranged ahead of the first-mentioned groove and aperture, in the direction of travel of oil thru'the burner, to form strainer ducts when the disk is held against a coacting surface of the nozzle. y

4. A spraying nozzle for an oil burner, according to claim 3, in which the tangent groove and the strainer grooves are connected by an annular groove also in said surface of v the disk.

5.`In an oil burner, a nozzle for the discharge of an oil spray, comprising a disk having a spray groove and a set of strainer groovesin the forni of open channels in the disk, kall of said grooves being in the same surface of the disk and the spray groove being connected with the strainer grooves, each ofthe strainer grooves being of less capacity than the spray groove, and the grooves being arranged to form ducts when the disk is held against a coacting surface of the nozzle.

v6.. In an oil burner, a nozzle for the discharge of an oil spray, comprising'a disk having a discharge aperture and having a groove tangent to the aperture and having strainer grooves connected with the tangent groove, all of said grooves being in the form of open channels and being in the same surface of the disk, and a body portion of theV ramer? nozzle in contact with said surface closing the tops of the channels, whereby to form ducts.

7. In an oil burner, a nozzle for the discharge of an oil spray, comprising a disk having a discharge aperture, having a spray groove feeding into said aperture, and havingstrainer grooves connected with the spray groove, all of said grooves being in the same surface of the disk, each of the strainer grooves being of less capacity than the discharge aperture and the grooves being arsignature.
