`To qllwhom it may concern:

Be it known that l, GEORGE FRASER, a citizen of the United States, residing at Toeka, in the county ol' Shawnee. and State ol' iansas, have invented certain new and useful Im roveinents inOil-Burning Revcrberatory maccs, oi' which the following is a specification. 'Y

My invention relates in general to i'urnaces, and more partitudarly to oil burning reverberatory furnaces.

The primary object of my invention is to provide :a reverberatory furnace in which crude oil or residuum may be successfully burned bv thoroughly mixing the sprayed. liquid fuel with an air blast in suitable quantities, reflecting and concentrating the generated heat to produce perfect. combustion, and discharging the gases in a state ol' pcrfect combustion into a working chamber, thereby resulting in a. high, uniform, and evenly distributed heat, l'ree l'rom violent drafts, throughout the entire working cham-V ber.

A furtherobject. of my invention is to prof- Vide'an oil 'burnimr reverberatory l'urnacc,

which will be simptie in cimstructtm, inexpensive in manufacture, and` eliicient in use.

The embodiment oi my invent-ion hcrein disclosed niay oe generally described as comprising an initial chamber, through o )cnings 1n the wall ot' which a plurality ol' mrners concentrioally extend, each'lairner comprismg inner and outer concentric tubes, an air Supply conduit communicating with tho outer burner tubes, an oil su plyconduit.

iiurner tubes, a bridge wall intermediate oi the initial Chamber and a working chamber, the top edge. of thc, bridge. wall being in the same, horizontal plane as the centers ot' the burners, openings leading into the. initial clnnnlwr adjacent the bottom thereof through which air is su iplicd, valves for regulating theI supply of oil to the burners, gates controlling the supply of air both to burners and to the lower openings, steam supply conduits communicating with the inner tubes ol' the burn ors, and' valves controlling thc supply of, steam to the burners.

Mv invention will be more' fully described hereinafter with rctcrencc to the accompanying drawings, in which thc saine is illustrated as embodied in aconvenicnt and practical form, and in which Figure lis a t'ront elevational view; Fig. 2, a central sectional view, showing one of the. burners on an enlarged scale; and Fier. 3, a vertical sectional viewon line, 3, 3, ig. 1., the surrounding wall being partially shown in elevation.

The sanie reference. characters are used to designate the salue parts in the several figurcs ot' the drawings.

Reference letter A indicates the housing of flanges a, a on thc adjacent sections. Q

B designates the trout of the housing, which is also preferably made in sections united by bolts extending through flanges vl). l) on thc adjacent sections, the front wall ol` thc housing being also united by bolt-s to the sidc walls A.

indicates the lire-brick liningof the ful'- nace, within which is formed an initial chamber lC and a. \\'orliing chamber l a bridge wall l) being provided intermediate of the said chambers. 'lhc initial cha mberEis -provided with au opening c leading thereto through which 'access may be had for the purpose of inspection. v l

j indicates one of the door vopenings leading to the working chamber for the introduction and removalof.v the material after being heated. Y

Extending horizont-idly through the front wall ot' thc tire-brickI lining are openings, such as indica-ted at Eand l.}2,'through which burners extend tothe interior of the initial chamber IC. Each ot the burners com rises an outer tube li' extending through tie corre.- sponi ling opening, but spaced apart therefrom to form an anun ar passageway, and an inner tu be h located concentrioally within the outer tube( A nozzleor con-ical cap i is secured ,around the inner end of the outer tube/H of' each burner, so as to torni a restricted annular passageway leading to the interior of the initial chamber around the central tube and a'ir supply conduit through which .air is forced at a suitable press-nre, as, for instance, about eight ounces. An air conduit G is. provided with branches it and G extending through opcningsin the furnace front to the interior o the initial chamber adjacent the bottom thereof. Gates g and g2 are rovided for controlling the passa e of air though such branched' conduits. he air su )ply conduitr y G is also'providcd with upwardly diverging a. furnace, which is preferably made in sec!4 tionsunited by bolts extending through 9; 'I esente branches'l-l, H2, which eoiiiiiiiiiiieate with the Outer-tubes U of the burners.
