Application filed March 10; 1913. Serial No. 753.223.

s cisco and State of California, have invented new and useful liiiprovenlen'ts in Atomizersv for Oil-Burners, of which the following is a specification.

. 'This invention" relates to a gear atomizer 10 for oil burners.

air before being delivered to the combustion chamber ofja furnace.

The invention consists of the parts "and the construction and con'ibination of parts as hereinafter more fully described and 0 claimed,-having reference to the accompany ing drawings, in which Figure 1 is a plan view partly in section. showing the application of the mechanical atomizer. Fig. 2 is a central, vertical sec Fig. 3 is a plan view of a pair of feed rolls, showing a modified form of same.

Referring to the drawings: A indicates a nozzle of any suitable construction, in the lower portion of which is formed a recess or pocket 2, to which crude oil or a similar product is delivered through a pipe 3. Suitably journaled with relation to the oil pocket 2, in a pair ofcross arms 4, suitably secured in the sides of the nozzle, a pair ofintermeshing spur gearso and 6, one .of which is secured upon a driving shaft 7, direct connected to an electric motor or similar means, not here shown. Mounted upon the shaft '4' 40 is a blower or fan 8, provided for the purpose of producing a forced draft through the nozzle. In operation it can be seen that the gears are so positioned with relation to the oil level in the pocket '3 that-the lower periphery or teeth of the gears will be partly submerged in the oil, or will come into suili cient contact with same to elevate a continuous film of oil which is constantly thrown up between the gears in the direction of arrow at, by the centrifugal action of the gears; the thickness of the pro ected oil film being determined by the relative it or position of the gears with relation to each other.

The thin spray or. film of oiltlirown up between the gears is instantly subjected tothe forced draft passing through the nozzle, and'is tnus turther broken .up or alomized beforo'hcing discharged from the nozzle lip into the furnace. The oil level vizilhin the pocket 2,,is entirely controlled by the position of the gears with relation to the oil surface. Any excessive feedof oil through pipe 3 would be instantly lllt'l-Illl up both by the peripheral surface and side surfaces ofth'e; gears and projected into the forced draft passing through the nozzle.- thus insuring againstany'overtlow or back flow from the nozzle. 1 r B y referring to Fig. 3,11 have shown a pair off-contacting rollers,'lhe surfaces of which are grooved or corrugated as shown at 9. The grooved or corrugated s 'lrfaccs. shown, are provided for the purpose of increasing the peripheral surface area without increasing the width of the roller. ll v' referring to Fig. 2, I wish it understood that the fan or blower indicated at 8, in some instances may be entirely eliminated, and that the forced air current may be supplied from any suitable'source; as. a;

I wish it understood that various changes in form and proportions'aud minor details of construction may be resorted to within- /the scope of the appended claims. and that I do not wish to limit myself to the specific design and construction here shown.-

I Having thus described my invention, what l claim and desire to secure by Letters Pat;

The combination. in. an oil burner, of a, condui, having an air inlet, an oil inlet and a fuel discharge orifice, av shaft within tho conduit, a fan. on tho shaft for c eaiing an all barge orifice, and inficrmeshing 11o driven. from the shaft. and on the oil from the 'oil inlet to project the oil into the all blast.
