To all whom-may concern: s

Be it known that I, CURTIS C. LILLI- BRIDGE, a citizen of the United States, residing at Hutchinson, in-the county. of Reno and State of Kansas, haveinvented certain new and useful Improvements in Oil-Burners; and I do declare the following tobe-a full, clear, and exact description of the invention, such as will enable. others'skilled' in the art to which it appertains to make and use the same. I a

My invention relates to that class of burn ers known as oil gas burners, in which hydrocarbon oils are first vaporized and then burned.

The object of the invention is to provide an improved burner oi this class which may be usedin stoves, ranges, furnaces or other fire boxes, as a substitute for other fuels.

A special object of the invention :is to improve such burners with a. view toreduc: ing the number of parts, and'consequently (the cost, and increasing the efficiency or heating capacity.

Vith this and other: objects inview, -my invention consists inthe improved-construe? tion, arrangement and combinationof parts of a'burner of this class, w hich will be more b the complete burner taken on a diametric plane; Fig. 4 represents a bottom plan view' of the upper member or. spreader; and Fig.

5 represents a top plan view of the lower or base member.

Like reference characters mark the same parts wherever they occur in the various figures of .the drawing.

Referring specifically to'the drawings, 1

indicates the base member and 2 the upper member or spreader. The base member 1 is preferably, in the form of a circular bowl having its,side walls inclined inwardly towiird its lower end and provided, at a short distance inwardly from the lower end, with displacement when in use.

a ring 3, concentrically located with reference to the walls of the bowl and connected thereto by'an annnlarporti'oni of thebottorln, forming an annular drip ordrain channe 0.

The ring 3 is slightly conical, its

walls inclining inwardly from theirbottmn upward and mounted on and integral with the upper edge of said'ring, .is a skeleton truncated cone 6 which is interrupted by a plurality of segmental draft open ri =7 alternating with radial arms 8, which are provided with grooves or channels 9 in-their.

upper faces, merging into the'upp'er-part 10 of the cone, whichis centrally provided with a segmental depression 11 from the center of which depends an oil supplypipe 13.

'The upper member or spreader 2. comprises a structure ot substantially :inyerted truncated conical form, the central portion of the bottom thereof being provided with a segmental recess 13 which, when :thismem her is in position on the basemcmber, as

shown in Figs: '1' to 3 of. the. drawings, is

seated upon and partially incloscs the up-v per end of the interior cone of, the base member. The upper portion of the spreader,-

or upper member 2'is made hollow as at 14 in order to lighten the structure. Projecting radially from the upper edge of the upper member 2' are arms 15,.v'vhich are of a proper length and beveledlon' thfeirou'ter ends at 15 .to engage vpartiallyfin,the' upper end of the base member 1, when the memher 2 is resting thereon. as before "describei' said arms entering partiallyinto the bowlof the base member and serving to st eadyf the. upper member or spreader and-prevent its In the use ofmy inventibn,"oi l' supplied through the tube 12 rises into the depression 11 at the summit of the interior cone of the base member, and when' a sutlicient amount has entered this depression, it overflows into and through the channels 9, finally reaching the annular drip or drain channel 5. When the oil is lighted. it heats all parts of the burner and the oil'coming in contact with the heated parts rapidly vaporizes and is consumed in its'vapor form, the inverted conic-a1 form of theupper member or spreader 2 serving to spread the blaze. and sufficient air is provided through the draft openings 7 to properly' mix with the vaporized oil. and burn with an in tensely hot fiame.

By reason of the necuhar arrangement of parts, as described, the oil supply pipe is not exposed to the flame and is, therefore, in no that I have reduced the number of parts of burners of this class to two only, and that these parts are of simple construction, pref senting no forms difficult to manufacture.

I My bu rncr may, therefore, be ve v econom1- 'cally constructed and, inasniuci as thev parts are of stout, heavy construction, they will not be-liable to be cracked by expansion or contract-ion due to heat or cold, nor'will they be liable to breaka' e in ordinary use.

\Vhil'e I have speci cally. described the exact construction and arrangement of V9.- rious parts of my burner, it will be obvious to those skilled in the art that changes and variations may be made in the form of the parts without'departing from the spirit and scope of the invention.

Having thus fully described my invention what I claim as new and desire to'secure by Letters-Patent is:

1. A burner of the class 'describedcomprising a base having a central draft opening and an annular drip channel, an integral ring rising from the base around said opening and forming the inner wall of said channel,'upwardly converging arms formed integrally with said ring with segmental open-. ings between them, the upper sides-of the, arms having grooves leading to said channel, and a truncated cone formed integral with the upper ends of said armsand having an oil depression.communicating with the'uppcr ends of said grooves; combined with an upper flame-spreading member hav-' ing flaring walls to 'spreadthe flame and formed with a depression in the center of-its' under side to partially encompass 'the cone and'the depression in the latter. r

2. A burner of the class described comprising a base having a central draft opening and an annulardrip channel, an integral ring rising from the base around said opening and forming the inner wall of said I channel, upwardly convergingarms formed integrally withsaid ring with segmental openings between them, the upper sides of v conicalpart of said basemember, and arms radiating integrally from said flaring wall with their outer ends shaped to. fit within the surrounding wall of the base member.

3. A burner of the class described comprising a base member provided with fiar mg walls, an annular drip channel, a central oil receptacle, and radiating distributing channels between the oil receptacle and drip channel, in combination with an upper and distributing channels between the oil re ceptacle and drip channel in combination with an upper member provided with a depression to cover the oil receptacle, flaring walls to spread the flame, and radiating igember in inverted conical shape provided with a depression to.cover the oil receptacle,

arms having beveled outer ends fitting withinthe upper 'edges of the flaring walls of the, base member. 4 I In testimony whereof I have hereunto set my hand in presence of two subscribing witnesscs.
