Application filed June 17,A

To all whom t may cmi-cern:

Be it known th citizen of the United in the county of Dunn and State have invented certain new and Menomonie,

of 'Wisconsim useful Improvements l thevfollowing to be a full, description of the invention, able others skilled in the art do hereby declare clear, and exact Vsuoli as will en to which it apper saine'.

This invention at l, VVILBUR A. Giiovnn, a States, residing at in Gas Burners ;-and I tains to make and use the relates to a liquid fuel suoli a burner having gas generating means therein. Such n burners are now commonly used in domestic stoves and ranges and also in connection with domestic furnaces.

It is an object vide a burner of of vthis invention t-o provsimple and efficient con-l struction having a .series of burner tubes, a

portion or all of one time.

It is a further pro-vide a burner ,burner tubes, va abovek the burner liquid fuel is pas brass filings.

provide a which-may be burned at object of the invention to having av plurality of generator tube ldisposedv tubes through which the sed, .which generator tubev divided metal such as invention toy having a plurality of tubes connected at their ends to supply conduits which are connected to one side of amixing chamber, said mixing chamber being connected to a generatingtube disposed over which generating the burner tubes, tube is provided with a plurality of fine screens.

. These and other objects andl advantages of the .invention will be fully set forth inthe following description made in connection with the accompanying like reference characters parts throughout which, I

Figp is a view in side elevation of a ring used; Vand a f Fig. 6 is a view of a screen usedin the Referring to the drawings, a supply pipe 1 is shown which will'be connected to an oil supply tank or means so that oil will be fed thereto by gravity or pressure. Said pipe 1 is connected by a suitable union member 2 to a generating tube 3 extending horizontally, which tube has disposed therein a considerable distance from the'member 2, a reduction union or nipple 4. A portion 3a of the generating tube 3 extends from the reduced end of the nipple 4 and is laterally' curved substantially in a semi-circle and connected to one side of a inixingchamber 5, a set screw 6 holding the portion 3a inra reduced extension 5a 0f said mixing chamber. The nipple 4 has a vshoulder formed therein and plurality of fine mesh screens 7 are disposed in said nipple, said screens being spaced by small rings 8 disposed therebetween.` The screen in one end abuts said the other end engages the end of the leg portion of generating tube y3 which holds the screens in proper position. The screens 7 preferably are progressively of finer mesh toward the portion. 3a; The portion of the preferably is filled with finely divided metal such as brass filings. rlhe portion 3a has its lend which is'disposed Vin the mixing chamber 5 closed save 'for a small discharge opening 3b and said end also has disposed therein a plurality of nfine mesh screens 9 spaced by suitable spacing rings 10 similar to the rings 8 already described. The mixing chamber 5, as shown in Fig. 3, comprises a hollow inember preferably of cast form having `a downwardly extending open-ended portion 5b. A

' conduit 11 extends from the side of mixing chamber 5 opposite the portion 3a, being held, in a projection 5c at one side of the mixing chamber a set screw 12. 1 The conduit 11 v is connected by an' elbow 13to a T'member distance below the conduit 11'.` Pipesvor conduits 15 and 16y extend, from the ends of T member 14 directions andhave their ends angles to extend which ends are in opposite bent substantially at right in nspaced parallel relation,

closed by suitable plugs 1'?l and connected by a p'late 18 extending.therebetween, said plate being connected tothe plugs 1 7 by headed screws 19. A small plateA or bracket 5 25 connects conduit 15 to the union 2 and forms a support for the latter and pipe. .l. A valve is mounted in the conduit 16 adjacent the T 14C equippedwith anloperating handle 21 projecting upwardly through the conduitfl. pluralityof. spaced parallel tubes 22 extend between parallel portionsof the conduits -15 and;I 16a-The tubes -22'a1e provided With spacedtransverse slits .Qiextending across substantially..v the top half of said tubes.
