Application led September 10 which is freely removable from the burner.

body for the 4purpose described,'and whichat the same time has a tight sealing connection with the body against any possibility of the leaka e of fuel between the meeting surfaces of t e cap and body when said cap is applied. l Still another object ofthe invention .is to provide a two-part sectional burner of the character described in which theburner body is coupled to a mixing tube from which it is adapted to be slipped olf, whereby the burner sections lare rendered readily removable from the fuel supplying means and from each other so as to allow the burner as a whole to be cleaned with the 'greatest possible ease and freedom.

Still. another object of the -invention is to provide a'burner havin means for securving in a sim le and e cient manner a thorough adnuxture of the fuel elements before lgnition'and the burning of the fue] so as to reduce carbon deposits to a minimum and' produce a ilame'of the greatest possible intensity. Y A

The invention consists-of the features of construction, `combination and arrangement of parts, hereinafter fully described and claimed, reference beiiig had to the accompanying drawing, .in which f Figure 1 is a side elevation of the burner.

Figure 2 is a top plan view thereof.

- Figure 3 is a vertical section on the line 3 3 of Figure 2.

In the embodiment of my invention as herein disclosed, I provide .a burner composed of `,a lbody or'case section 1 and a top or cap section 2,.the burner as a whole being enel-ally of circular form, although any oter suitable form may be employed. Thebody or base section 1 has a\lower circular sleeve portion 3 of minimum diameter an upper rim portion 4 of major diameter, and '(ani'ntermediate tapering portion 5. At

5, 1925. serianA No. 54,802.

the juncture of the portions 4 and 5 a hori-v zontal shoulder 6 is formed, from the outer edge of which the lportion 4 extends upwardly in the shape of a projecting flange.

The cap section 2 comprises an annular body portlon 7 open at its bottom and closed at its top by a crown -wall 8. The upper portion of the body 7 is provided with"an annular shoulder 9 whereby it is thickened, the lower half of the body below theline of thev shoulderf9 formingl a de ending flange 10. The shoulder 9 an upper portion of the body 7 lare of greater diameter than the wall and between the. upper peripheral edge ofthe shoulder 9 and the peripheral edge of the wall 8 the outer surface of the wall 7 is stepped or beveled, as indicated at 11, at a suitable angle to the plane of the cap body. Through 'this beveled portion of the burner are formed a plurality of jet openings-12 said openings extending .upwardly and outwardly at oblique angles to the beveled por tion 11 and tangential or eccentric to thel axis of the burner. By this arrangement of the openings 12 the jets of {iames or products of combustion -from the burner will becaused to travel in a spiral vpath around and in af direction across the top of the burner, thus increasing the'range of travel of the iames and products so that a vessel or utensil resting upon the burner or supportedwabove the same will be more highly heated and -a greater proportion of the available' heat utilized and waste of heat materially reduced.` The .burner body 5 is mounted upon a mixing tube or chamber 13, provided with an external annular supporting shoulder1'14. The external surface of the upper end of the tube above said shoulder is smooth-surfaced and receives 'the sleeve portion 3 of the'body 5 which snugly encompasses such portion of `the tube and rests upon theshoulder 14.

The portion 3 engages the smooth-surfaced upper end ofthe tube sufliciently tight to provide a close joint and yet suiciently loose to adapt the burner to be slidably applied and removed. Below the shoulder 14 the lower end of the tube is externally threaded, as at 15, to receive an internally threaded hollow head orl nuts 16 having air i inlet openings 17 of a prescribed size. Fitl entering through the nipple 18, having a passage of fixed dimensions, entrains with it air flowing through the .openings 17, the airand gas passing lupwardly'through the tube 13 into the burner. The length of the 10 uppeige'nd o'f the tube 13 above the shoulder 14 is'such that the upper end ,of said tube terminates close to and a short distance below the wall 8 of the cap`2:A As a result,4the `air`and gas entering' through the tube 13 l will strike the underside of the wall 8, acting as a bafile plate, causing the stream of air and gas to beimpelled downward into the bowl-shaped chamber of the base 1 and to 'be thereby agitated and thoroughly .20 mixedV therein beforedischarging' through the jet apertures 12. Provision is thus made for securing, 1n a slmple and effective `manner, a proper combination of the air and gas constituents before ignition thereof in order to secure a reduction of carbon deposits and to produce an intense flame.

Byreason of the described construction of the burner body 1 and the tube 13, it will be seen that the burner as a whole has a slip-connection with ther upper end of the tube and may therefore be readily and conveniently applied or removed by simple endwise up and down movement, permitting of theassemblageof the parts and their dis-l assemblage in a quick,l ready and convenient manner. VAlso it will be seen that by the' detachable connection of the cap section 2 Y with the.l body 1, such cap section may be readily applied to the body and as readily 0 and conveniently removed therefrom. This permits of the cap section alone or of the entire burner being removed and its `sections disassembled for the purpose of rendering the same easily accessible for the cleaning 45 out of carbon, grease and other deposits. In

practice, the shoulder portion ,9'iof the Cap section and rim edge of the flange 4 of the body are made smooth-surfaced for a ground j' joint engagement, so that,while the ca is mounted so that it maybe easily 'lifte off the body, a sealed joint will be provided A which will be proof against the leakage of the fuel. The flange 10 isXalso preferably made of slightly less-diameter than the internal diameter of the fiange 4allowin0f sufficient space for expansion of the wall under the action .of heat-without liability of the cap section warping or becoming bound upon the body section. -The flange 10 may `terminate above shoulder 4' or may extend down to .and seat in said shoulder, as ,de-

- sired.

f As shown, the stepped or beveled portion 11 of the cap section is referably corru- 55 gated or fiuted, forming ri es which agitate ably supporting andcause a thorough nalmixture of the. fuel constituents at the moment of ignition, thus further promoting thorough combustion of the fuel. Y f The construction of burner described ensures maximum simplicity, maximum efliciency in the mixinggofl the air and gas, so that an intense flame will be produced with a minimum liberation and deposit of carbon, and maximum convenience in the assemblage and disassemblage ofthe' burner parts and in permitting access to suclu parts for the removal of depositswheneverrequired.
