IMPROVEMENT IN COAL-OIL BURNERS Specification forming part of Letters Patent No, 47,38 l, dated April 25, lS65.

To all whom. t may concern:

Be it known that I, W. WrBATCHELDER, of New York, in the county and State of New York, have invented certain new and useful Improvements in ,Coal-Oil, Vapor, s or Gas Burners; and I (lo hereby declare that the following' is a full, clear, and exact description of the same, reference being had to the accompanying drawings.. in which- 4 Figure 1 is a sectional elevation ot' a lamp with a burner constructed in accordance with this my invention attached; Fig. 2, an inverted plan view of the upper part of said burner.

My invention relates to coal oil burners ill which the oil is Ijrst converted into vapor or gas, which vapor-or gas is mixed with atmospheric air and burned at the part where it issues from the burner; and it consists in the employment, in combination with a tubular wickholder and vapor or gas generating and air-mixing chamber, of a perforated plate, or the equivalent thereof, together with a metallic or other heat conductor or conductors projecting downward and dipping into the wick substantially in the manner hereinafter described, for operation as herein set forth.

To enable others to make and use my invention, I shall now proceed to describe the construction and arrangement of my said burner, and referring to the drawings.

A is the fluid reservoir or vessel which contains the coal-oil. It is provided with a screw-threaded cap, B, fitting and closing' an opening, through which the oil may be poured Without interference with the burner. rl`he burner proper is composed of an upright wicktube, C, soldered or made in one piece with the cap D, screwed onto the collar E. Upon this wick-tube is fitted, byrfriction or otherwise, so as to admit of vertical adjustment in relation thereto, a concentric tube, F, provided at its lower end with a flange, Gr, for the support of the vaporizing-chamber II. The office of this outer tube, F, is to regulate the wick, contracting or spreading it more or less, according to the volume ot vapor desired to be generated. The vaporizing-chamber H is cylindre-conical, or of any convenient or suitable form, open at the bottom, so that air may have free access to the wick at the top of the wick-tube. It is for that purpose held by means of a colla-r, I, surrounding the tube F, and resting upon the flange G, and by means of bracing-wires J. The upper part ot' this chamber is contracted, and

terminates into a attencd top, leaving a narrow slot or space, K, through which the vapors issue, spread in the form'of a fan. .I ust below the attened portion of the chamber,

and imme=liately above the outer tube, E, (when thc vaporizing chamber is Iittedinto its seat,) there is arranged a horizontal disk, M, perforated by numerous holes and provided with a metallic cone, N, held concentrically with the said disk, and so as to preject downward and centrally into the wicktube. 'Ihc arrangement of this disk Mis such in relation to wick-tube as to intercept the llame near thewick-tube 'at the blue part thereof,.which is that portion .of the flame.

which is not illuminating, but possesses great heatingcapacity. Thedisk,andconscquently the cone N, which is placed or held in the with atmospheric air, at the top ofthe burner,

where they are burned, producing a brilliant and steady light without the aid of a chimney.

Having thus described my invention and the nia-nner in which the same is or may be carried into cii'ect, I claim- 'lhe employment, in combination with a tubular wick-holder and vapor or gas generating and air-mixing chamber, of a perforated plate, or the equivalent thereof, together with a metallic or other heat conductoror conductors projecting downward and dipping into the wick, substantially in the manner herein described, for operation as herein set forth.

In testimony whereof I have signed my name to this specification before two subscribing witnesses.

XVILLIAM W. BATCHELDER.
