Patented Aug. 8, i929 Application filed December 31, 1919. Serial No. 348,553.

To all whom t may concern:

Be it known that I JOHN F. BANNON, a citizen of the United tates, and resident of Bayonne, in the county ot Hudson and State of New Jersey, have invented certain new and useful improvements in Oil Burners, of which the following is a specification.

rThis invention relates to an oil burner, and its object is the production of a burner, for liquid fuel, whereby the latter h-as transmitted thereto heat from the vaporizing agent before vaporization takes place. This is accomplished by making the outlet port of the steam chamber of a small cross area so that the steam therein will be held in check. The oil chamber is adjacent to the steam chamber and thereby the oil in the former is easily heated. A detachable cap for the nose end of the burner allows the latter to be easily cleaned.

ln the accompanying drawings, Fig. l represents an exempliiication of the improved burner; Fig. 2 shows a section oi' Fig. l on the line 2, 2; Fig. 3 is a left hand end view of Fig. l; Fig. 4 shows a section of the burner as on the line 4, 4 of Fig. 2; and Fig. 5 represents a section as on the line 5, 5 of Fig. 2.

The burner is shown with the body portion 2O which has formed therewith at one end the exterior thread 21 and an opening with the interior thread 22. The other end of said body portion has formed therewith the nose end 23 with the supporting rib 24. An oil chamber 25 in the body portion 20 at its outlet end has connected thereto the tapering outlet port 26 and its inlet end 27 is threaded for oil supply piping not shown. An oil well 28 spaced Yfrom the oil chamber 25 is formed in the nose end 23 and at one end at the lower portion thereof connects with the port 26. The oil well 28 at its outlet end terminates in the segmental diverging outlet portion 29. A needle valve is indicated with the tapered end 32, shank .33, enlarged threaded portion 34 and the operating handle 35. A screw cap 36 engages the exterior thread 2l and has an opening 37 which constitutes a guide for the shank 33. The tapered end 32 can be seated on the tapered port 26 to either adjust the quantity of oil flowing through said port or to cut off the supply of oil altogether.

A steam chamber 38 having the inlet opening 39 (threaded for steam piping not shown) at one end and the flange 40 at its other end is formed with'the body portion 2O over the oil chamber 25. A detachable cap or lip 4l has formed therewith the V shaped port 42. The latter connects the steam chamber'38 and the top or the oil well 28.

F langes 43 and 44 are formed with the cap 4l. The flange 43 is secured to the flange 40 by means of screws 45 and the flange 44 is secured to the nose end 23 over the segmental outlet portion 29 by means of the screws 46 and forms with said portion 29 an outlet port for the burner.

ln operating the burner, oil is fed to the oil chamber 25 through inlet end 27 and steam is allowed to iiow into the steam chamber 33, by reason of which kthe oil in the chamber 25 will become warm and then How through the outlet port 26 into the oil well 28. rIhe steam will be held in check in the chamber 33 on account of the small cross area or" the V shaped port 42. As the steam rushes through the port 42 it picks up oil from the oil well 23 and vaporizes it, causing the mixture or" vaporized oil and steam to be discharged from the diverging segmental outlet port 29 into the furnace for which it is used, in a diverging flat zone of vapor.

The burner can be modified by dispensing with the needle valve and replacing the screw cap 36 with a cap without an opening. therethrough.

Having described my invention what l desire to secure by Letters Patent and claim 1szl. In a burner for liquid fuel the combination oi a body portion with a nose end and having a steam chamber and an oil chamber adjacent one to the other, said nose end having an oil well spaced from said oil chamber and having a port connecting it with the oil chamber, a detachable cap 'for said nose end covering said oil well and one end of the steam chamber, said cap having a port connecting the steam chamber and the top of said oil well, said cap forming an outlet port with the upper portion of the oil well 'for the burner, means to furnish steam to the steam chamber and means to furnish oil to the oil chamber.

2. ln a burner for liquid fuel the combination of a body portion with a nose end and having a steam chamber with an inlet opening, said body port-ion also having' an oil chamber adjacent to the steam chamber with inlet end and an outlet port, said nose end having an oil Well. spaced from the oil chamber and connecting et its lower end with vthe outlet port o't the oil chamber, saidy Well having; a diverging segmental outletv portion, said Well at its top connecting' with e port in the burner leading to the steam Chamber7 the latter port directing a. flow of steam to the top portion of the oil Well7 causing' it to pick 11p oil from seid Well,

Vaporizing it and forcing the mixture of oil sind steam to be discharged 'from the burner.
