o Lgf lnvenfor Francis H. Alamb to the burner and emerges from the passages '19 in fine jets. The air from 'the manifold passes through the burner body 6 and passages and 2l. The air entering the burner escapes through the aperture 17, z'. e., through' the annular passage left between the walls of the aperture and the burner. As this passage is considerably restricted the air attains great velocity so that on com.

ing in contact with the oil jets it breaks the same u into 'a fine spray. This breaking upx` of t e jets is further assisted b the air w ich blows into the slots 18 an centers in a forwardly moving blast between the oil' jets. 'The air-entering the passage 20 escapes through the annular apeture 24, and

` forms la code of air around the oil jets which is cau ht and carried forward. The oil spray ',m'the burner strikes against the rod 31 and is.,thereby thrown into the air core issuing from the aperture 24. This repeated mixing of the oil with air produces a resultant gas of very high thermal eilicienc7 which burns with a clear smokeless flame. The air from'the passage 21 enters the combustion chamber through the passages 28, and providesl an'additional supply of oxygen to insure perfect combustion. The updra from the bottom passage 28 also tends to lift the fiam'e above the bridge 26. It will be understood that after the. burner has been in operation for a short time the combustion vchamber and casing? become very hot, and that by passing'the air through the passages 20 'and A21 it is heated sutiiciently to insure perfect evaporation of the oil and at the same time prevent the blast of cold air. from striking the flame. The bridge wali throws the fiame up and concentrates the same and also serves to stop particles of oil and soot, and prevent their entrance into the' furnace. The purpose .of sloping the rod 31 is that should liquid oil collect thereon and run down, it will not soak into the brick as it would i'fth'e rod were vertical, but will be evaporated in its passage down the rod by the air emerging .from the bottom aperture 28.

Havin declare t at what I claim is4 1. A device of the character described comprising a casing an air passage at the back of said casing, a combustion chamber Vsupported by said casing, an air passage in the side of the combustion chamber for admittinv air thereto, a burner body associated with t e combustion chamber, a burner inv said body, a defiector supported within said combustion chamber, and a baille located in the mouth of said combustion chamber, for throwing the dame upward.

2. An oil burner comprising a body hav ing a taperingoutlet, a tip supported in said outlet whereb a tapering annular orifice is formed, sai tip having a plurality of oil ducts spaced from the center thereof, means for heating air and a tapering annular oritice from said air heating means surrounding said first named orifice.

3. A device ofthe class described comprising a burner, a casing, an air passage at the back of said casing, a second air passage at the sides and bottom of the casing, a combustion vchamber supported by the casing, an air manifold connected to said burner and passages, an annular orifice leading from the first passage into the combustion chamber at the rear, conduits leading from the .second passage into the combustion 'chamber at the sides and bottom.

4. A device of the class described comprising a burner, a casing having air passages therein, a combustion chamber supported in said casing, an air manifold connected to said burner and air passages, an air inlet at the rear of the combustion chamber arranged to form a cone of air in front of the burner,

means for throwing the oil from the burner into said air cone, air inlets at the sides and bottom of the combustion chamber, means for controllin the iiow of air through said air inlets an Ameans for concentrating the flame of combustion.

-In witness whereof I have hereunto set my hand in the presence of two witnesses.
