OIL-BURNER.

Specification of Letters Patent.

Patented Sept. 1, 1908.

Application filed April 3, 1908. Serial No. 424,883. 7

To all whom it may: concern:

Be it known that 1, JAMES C. FITZSIM- Mons, citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Oil-Burners, of Which the following is a specification.

' -My invention relates to oil-burners, and oil-burners employing crude oil or heavy distillate and air as a volatilizing me- VVith burners in which air is used to volatiliae the oil, it is essential, or at least highly preferable, for practical results, to bring the oil and air together inside the burner, and to' Long experience with nection' with boilers, has taught me that best results are obtained where the passages in the burner are as small as possible.

. The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying draw- Figure 1 is a longitudinal section of my burner head. Fig. 2 is a plan view of same.

A represents a burner head of special construction adapted to be screwed on over the end of the air pipe 2. 3 is the oil pi e arranged concentric with the air pipe 2 an se arated from the airpipe 2; the outer end 0 the oil pipe being suitably supported in the hollow spacingmember i. This spacing member 4 comprises a ring into which the oil'pipe 3 screws, and having the legs 5 engaging the and also having a part 6 around which the oil is deflected laterally and is brought into intimate association with the body of air in the burner.

The air and liberated oil are thoroughly commingled in the mixing chamber-7 in the burner head A; From this mixing chamber wardly projecting forked nose 9.

7 extend two vapor passages 8 into the forportion 9 is made substantially half round, and this is split to-receive a short piece of tubing 10, preferably open at both ends, and in communication with the passages 8, and having a transverse discharge slot 11 of suitable depth and thickness through which the commingled oil and air is discharged as an inflammable va or into the furnace. The part 10 preferab y consists of a short section ,cl amped in position.

The nose of thin steel tubing, the thinner "the better, and fits in a recess formed by the u per and lower portions of the nose 9. A sing e bolt 12 passesdownthroughtheheadA,andbymeans of a nut 13 the tube section 10 is securely The de th of the slot .11 depends on the character 0' the flame desired. The deeper the slot, the more fan.- shaped the flame. The tube 10 can be turned to right or left to send the flame more or of the burner. By having the tube 10. open less to one side or the other of the axial line at both ends, I am able to use a compara tively small diameter of tubing, because the tube is thereby enabled to carry twice as much vapor as it would if the vapor could enter only at one end. By this construction of burner, the oil and air are thoroughly, commin'gled mside the head, and the discharge through the slot 11 is as a single vapor, which is readily ignited.

The oil and air pipes may be connected with any-suitable source of supply, and any means, not necessary here to be shown, may be employed to control the flow through h 'By suitably'slitting the tube section 1.0,

and properly adjusting the section in the burner to right or left, any sort of a fan shaped flame, wider or narrower, may be produced, and the flame can be made to fit the furnace.

The use of a single slot through which to discharge .all the inflammable vapon enables this slot to be made larger than where separate steam and oil passages are necessar and consequently a steadier and better flame can be had, since there is less danger of clogging.

Having thus described my invention, what izing agent are commingled, means for sup-' plying oil and said agent to said chamber, an

a'ndecerident start section removably 5mg, with'said chamber, and a clamping bolt extending transversely through the split p01?- tien of the burner head fdr removably securiflg-the'secticn in position.

In testimony whereof-I havehereunto set my'hand in presence of two subscribing wit-- nessesh Y t JAMES C. FITZSIMMONS.
