Application September 16, 1944, Serial No. 554,506 1 Claim. (Cl. 15S-‘63) 1 This invention is directed to an improvement in oil burners, involving a completely portable unit designed for vaporizing and burning of waste oils, such as crank-case oil, but equally service able with other vaporizable fuels. The burner of this invention is constructed in two substantially similar parts, capable of being assembled in burner forming relation or readily separable for convenient and easy cleaning of carbon and other deposits, and involving simple and easily operated mean-s for securing the parts in burner-forming relation. An essential object of the invention is the pro vision of a burner of comparatively small size 2 of the rounded marginal area is materially greater than the width of the connecting web, and the free edges of the marginal areas are pref erably formed with strengthening Webs 5. The burner is assembled by bringing the straight edges and webs into contact, »and such straight edges may, if desired, be formed for mating cooperation to assist in sealing the junc ture. The openings 4 in the Iwebs 3 register when II) formed to present the maximum vaporizing and burning area when assembled, with the Vaporiz ing chamber formed to avoid the slightest inter ference with complete cleaning when necessary. the 'burner parts are assembled, and plates 'I are provided to overlie and bear on a round portion of each section in line with the openings ll. _Bolts ä are passed through holes in the plates 'I and through the registering holes 6 in the webs v3. One end of each bolt is headed at 9 and the op posite end formed with an opening to receive wedge keys I0, which after the application of the connection may be driven with sufficient tight ness to insure mating and sealing contact of the The burner as a whole comprises two identical edges of the sections. 20 annular sections, each of semi-circular form in As the plates 'I bear at their ends against the cross section, with a central web in line with their rounded surfaces of the sections they exert se inner edges, the sections being assembled with the nat edges in sealing contact by means of curing and sealing pressure at relatively remote points and against the rounded body of each tie-bolts passing through the assembled Iwebs section to insure complete connection and seal and through plates bearing against the rounded 25 mg.

The invention in its preferred form is illus trated in the accompanying drawings, in which: and affords ready access to the interior. Fur thermore, it will be noted that the interiors of the sections are rounded, hence avoiding any corners or other obstructions which might tend to prevent perfect cleaning of carbon or other Fig. 1 is an end elevation of the improved deposit.

The upper portion of the unit is formed with Fig. 6 is an elevation of the wedge key. an admission opening I3 to receive an oil-inlet The improved burner comprises two identi pipe I4, leading from a suitable source of sup cally formed sections I and 2, of any desired or 45 ply, and preferably having a suitable cut-oil, appropriate metal, formed to provide in each not necessary to illustrate. The pipe I4 has a section a central elongated web 3 of relatively wedged-shaped delivery end I4' within the narrow width, with an opening Il, extending en burner. A starting pan I5 is carried by the lower tirely around and conforming to the shape oi the web. Each section thus presents an oval body with a central web and with a completely uninterrupt ed marginal area of semi-circular form in sec section of the unit, in which readily inflammable 50 fuel is placed and ignited for heating the unit to an oil-vaporizing temperature. The starting pan I5 may be secured by welding or otherwise securing the same to the web 5 of one section tion, with the flat edge thereof in the plane of of the burner, as at I5'. A small quantity of one face of the connecting web. The diameter 55 3 2,409,095 oil is admitted to the interior of the unit through pipe I4, and the fuel in the starting pan is ig nited. The flame from the small- quantity of oil in the unit which is quickly vaporized by the starting fuel heat, is emitted through all holes II and I2, and when the unit is heated to vapor izing degree, the starting fuel is extinguished, or Having thus described the invention, what is An oil burner comprising a two part vapor izing chamber of circular form in cross section and oval form in elevation, both parts of the chamber being substantially similar in form. and through pipe I4, rapidly and completely vaporized and burned with the flame passing through the holes II, While the holes I2 admit air to sup of completely curved form throughout the in port combustion. The interior of the burner terior of each part, the two parts of the cham ber being hollow and iitted edge to edge to com unit is thus a mass of flame, raising the temper ature of the unit to a degree to utilize it as a plete a substantially closed chamber, the cham heating agent completely serviceable for cook ing, exterior room heating, or for other uses where heat is desired. It is important to note that the unit is of two ‘ quickly assembled in unit relation, and can be quickly and readily separated without tools or material labor when required for cleaning; and that the 'interior of the vaporizing chamber of the unit presents no corners or other obstructing parts to prevent thorough and quick cleaning of carb on or other clogging deposits. The burner may be made in any sizes and of any appropriate metal. The vaporizing cham ber may be of any size, so long as itis continuous and circular in section. The unit is completely portable and may be readily moved from place to place, as in a cooking stove or a heater cabinet, or wherever heat is desired. It will be understood that the pan I5 may if desired be secured to the burner proper, and that inlet pipe I4 and permitted to overflow through the holes I I and Iiow down ‘che exterior of the burner into the pan I 5. claimed as new is: the holes I2 are temporarily blocked to cut off the ñame, and the fuel to be burned is admitted similar parts, thus simple and economical to manufacture; that 'the parts are easily and such pan may be independently charged, or that oil may be admitted to the burner through the -ber having a central web in line with the junc tion of the meeting edges of the two parts of the chamber with the central web formed with an opening, a pin passed through said opening, a plate on each side of the chamber in parallelism with the central web through which the pin is passed, a head on one end of the pin to bear against one plate, and a wedge key to be passed through an opening in the pin to overly the other plate to secure the parts of the sectional cham ber removably together, a supply pipe entering the chamber near the top thereof, the chamber being formed in parallelism with the central web and throughout the length thereof with openings 30 for the escape of the vapor of the medium used. and further formed beyond such escape open ings with further openings for the admission of air to the chamber, the wedge key maintaining the junction of the chamber parts under a sealing tension and permitting ready separation of the chamber parts when desired.
