plate C;,and an outer flange p to fit over the edge of the wall which surrounds the opening q'. The opening or chamber p8 is threaded,

as shown at p7, to receive the threaded end of` a pipe E.

D is a damper which rests upon the upper surface of the top-plate B. It has a central annular projection n on its `under side to fit the'opening p8, and may beturned to regulate the sizes of the draft-openings p.

The consti-notion shown and described is designed lmore especially for vaporizing and burning hydrocarbon oil, which is fed through the pipe E. In practice the pipe E extends beyond one edge of the stove to which the' burner is applied and iS there connected, preferably, by means of a flexible rubber .hose with an oil lsupply tank, placed at any safe and convenient distance from the stove at an elevation with relation to the burner. In` practice I prefer to provide a small quantity-vv When the oilv is turned on at. the pipe F it flows into the chamber p3 anel thence through the funnel#V of asbestos Y in the recess t.

shaped opening p4 to the gutter s at the shallow part thereof. The gradually deepening shapeof the gutter causes the oil to fiowarouud the circle to the point Initially the oil is allowed to fill the gutter and overfiow through the opening 'r' and saturate the asbestosY.`

A match is then applied to the asbestos and theoil ignited. lhe natural tendency of the draft is toward the outlet flue of the stove. Consequently, air to supply combustion, enters through the draft-openings p and the products of combustion pass over the wall t2 to the outlets t2 and there escape into the Stove, As the products of combustion pass over the wall t2- they strike the lower V-shaped' surface of the plate B and soon heat the gutterportion of the latter to a high temperature. As a consequence the oil entering the gutter and flowing around the same is quickly vaporzed and caused to escape in the form of vapor and gas through the'annular burner opening r'. Th us while air enters the chamber formed by the gutter s it; covering plate C it is' immediately vaporized and more or less gasified and fills the chamber throughout and escapes equally through all parts of the burneropening'r. Consequently,asheet of flame of equal size and intensity is directed radially 4inwardly from the burner-opening and is carried downward under the flange s3, over the wall t2 and under the gutter s' to theoutlets t3, whence the products of combustion move backward in the stove, filling the flue-chambers or passages and heating all parts of the stove in the same way as when coal or wood are employed as the fuel. The size of the flame may be readily regulated by regulating the supply of oil flowing through the pipe E, a suitable valve,'of course, being provided for that purpose. The ingress of air to supply combustion may be easily and effectively regnlated by means of the damper D', so that the heat may be easily and eiectively controlled at all times.

IE it is desired to employ hydrocarbon gas, either natural or manufactured, instead of oil 7o as the fuel, the pipe E is connected with the gas supply, by means of a rubber hose or otherwise,and in the pipeE is interposed an air inlet valve, which may be on the principle of the Bunsen burner, to admit a desired quantty of air with, the gas tothe chamber s. The gas is heated in the chamber s' to a high temperature before it escapes from the burneropening 1*', and its combustion and heating qualities thus greatly/augmented.

The partsA B C D and D are not secured together and may therefore be readily sepa-v rated for purposes of cleaning and as readily replaced.

My improvement is adapted for cooking stoves and ranges generally, and, as before stated, fits into a stove-hole X of the stove or range-top Z. The vaporizing of the oil before it escapes'from the burneropeningrr', and the down draft which prevents the escape of lfumes through the top of the stove, makes the burner odorless; and itis, furthermore, perfectly safe,and economical. T-he spacing lugs p prevent a vessel, imposed upon the burner, from interfering with the draft.`

While I prefer to construct my improvements in every way as shown and described,

they may be modified in the matter of details of'construction without departing from the spirit of my invention as defined by' the rco claims. .l

What I claim as new, and desire to secure hyp/Letters Patent, is-

1. 4In a hydrocarbon burner, the combina- V tion of a dish-shaped casing having acircumro5 ferential flange at its upper side to lita stovehole, upper and lower annular burner plates fitting into said casing and affording an'annular vaporizing chamber above the base of the casing, and provided with a narrow continuous inner-circumferential burner-opening, a top plate upon the casing having an oil supply passage leading to said burner, and a central draft opening, a damper at the draft opening, and outlet openings in the casing about the lower burner plate, whereby products of combustion pass from the burner opening around the vaporizing chamber to heat the latter, substantially as described.

2. In a hydrocarbon burner, the combination of a dish-shaped base A, having a .circumferential flange at its upper side, to lita stove-hole,outlet-openings below the flange, and an inner annular wall t2, a top-plate having a draft opening, and a burner, mounted in the base A, having ,an aunula'r chamber provided at the top with an inner-circumferential burne'r opening, and an inner circumferential downward extending flange sa, the top-plate having a supply passage leading to 13o said chamber, substantially as described.
