. forretaining the retort in fixed relation to the generator under the varying conditions of expansion by heat, and to providea gas jet which may soot and other obstructions.

To this end my construction and forming an oil I fully vdescribed and particularlystated in the claim, reference being had to the accompanylng-l drawing in which: j v Figure I, is aside elevation'v of an oil burner according to my invention. Fig. II is a front elevation of the alcohol delivery device. Fig. III is a central vertical section partly in side elevation of my oil burner.

Fig; IV is a longitudinal section of thejet.

Fig. V` shows a horizontal section, partly in plan view, at line X, -Fig. III.

These oil burners are usually made in .pairs mountedv on a single base 7, to fit into the lire. box under two lids of a cooking stove. The heater comprises a chamber having a circular inner wall 8, a ilo'or 9, an' outer wall 10, of sheet metal having many perforations 11,A for the blaze to issue through; a cap 12, which.rests upon the louter wall and has a baffle ring 13 deit' withinthe chamber 8, 9.-

pending .from An intake tube 14 passes down through the ioor 9, and `has a flange'l resting thereon.

- one end 17 to engage a pipe the oil supply pipe, thence rising to the level of the floor and passing in a circle'around the outer wall 10 a little below the lower level of the perforations 1l, and supported on brackets The retort comprises 18 that are providedwith caps 19 and screw I bolts 20; thence dropping to about the level of its starting point 17, vand provided with a jet 21, the delivery nozzle 22 of which is located centrally under the intake tube 14, up intowhich the nozzle enters alittle in the county of Mason and State' be readily cleaned fromA y opened for cleaning. v[I he nozzle 22 is a invention consists 'in the combination of parts 1 burner hereinafter more. `opensl the nozzle -to `largerinnerend opening. `The brackets 18, rigidly attached to the ,pipe 29 that ymay be lof alcohol may 16 adapted atdering a stoppage. of the opening 23 liable at any moment if cleaning of the 'jet is' neglected.. To facilitate this' cleaning and insure its being well done, I t a conical plug 25, having a shoulder 26, into-one end of the jet 21 and provide a cap 27, with an "internal shoulder to engage the shoulder 26, and with a screw thread to screw upon they jet. This enables the operator to make a tight jointeven where kerosene oil is used,

and yet permi plug like,.25'eXcepting the delivery opening 23., and has the same advantages. It also be cleaned from the integral with or heating chamber, hold the circular portion of the retort 16, always in its fixed relation to the perforations 11, at which the burning l takes place, be the contraction and expansion what it may in practice. The base piece 7 'is formed as a pan at 30 to receive alcoho to be burned directly under the chamber 8,

9 to heat it .and the surrounding retort in l starting them to generate gas. To pour alcohol into the pan by usual means when there is re the stove is dangerous, therefore I provide a funnel 27 that may be hung by the loop hole28'at a safe distance from the' stove; a very small conducting bent or swung as required to reach the pan 30, and ast'opcock 31. By this means the desired quantity be easily and 'safely conducted to the pan at any time whether there is fire about the stove or not. In operation, oil is admitted to the retort at 17 and.

the usual stopcock in the supply pipe, not shown. Burnl the delivery regulated by ing alcohol in the pan 30 starts the conversion of oil into gas by heating the chamber 8, 9 and retort;` this gas is delivered by the jet nozzle 22 vinto the intake tube 14, then up into the said chamber where it lpasses down under the baffle 13, then up over the inner `wall 8 to the burner` apertures 11 in the 'outer wall 10 where it is to be lighted by a match. The circularl por tion of the retort 16,' located near the flame,

side pulfs of air from causingv ts Athe full size of the bore to be converts the oil into gas that would burn, but its quality as a heat producer is greatly improved by superheating it in the chamber 8, 9 Where it is retained by the battle arrangement; for that purpose and nally produces a flame of intense heat. Fairly good results are produced if the wail 8 be located farther from the wall l0, or even if it be entirely removed, but the intake tube 14, extending high up into thechamber 8, 9 and the baille 13 depending around that tube below the level .of its top are essential to the lbest results of this invention.

Iclaim: y In an oil burner, a heating chamber having -a floor with a rising` inner wall and a central opening;

` sheet material removably attached to the Genies of this patent may be obtained for ve cents each. by addressing an outer wall of perforated Leccese Hoor 'around and near to the inner Wall; an intake tube passlng through the Hoor and having a Harige resting removably thereon;

a cap resting on the outer wall and havinga bafe ring depending freely around the intake tube, and a delivery oil pipe located vas a retort around the heating chamber and WILLAM' COOKE.
