Specification forming part of Letters Patent No. 36,755, dated October 21, 1862.

To all whom it may concern:

Be it'known that I, GEORGE L. WITSIL,

of the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Burners for Goal-Oil Lamps; and I do hereby declare that the following is p a full, clear, and exact description of the construction and operation of the same, reference being had to theaccompanying drawings, making a part of this specification, in which Figure 1 is a side elevation; Fig. 2, a plan View, and Fig. 3 a central vertical section showing the wick applied, like letters indicating the same parts when in the different figures. Y

The object of this invention is the production of a burner for coal-oil lamps that will serve effectually in the combustion of the oil, so as to produce therefrom withonta chimney, a larger and brighter smokeless flame, and at the same time better protect the flame from beingextingnished by currents of air produced in'lifting and carrying the ignited lamp about, or otherwise.

It consists of two flat tapering air-flues arranged so as to be inclined toward each other at their upper ends and afford a large tapering wickchamber between, in combination with two deflectors curving over the upper endsof the said air-fines, respectively, and extending laterally beyond them on each side, the whole being constructed and arranged in relation to the supportingcap substantially in the mannerhereinafter described and specified.

In the drawings, A A are the two air-flnes; B, the wick-chamber; a a, the two deflectors, and G the supporting-cap.

The air-flnes A A are each formed of thin plate metal,and secured together between two flat supporting-plates, d d, so as to produce an inclined tapering passage way for discharging air on each of the two flat sides only of the upper end of the wick b, which projects a little above the said fines, the length of the upper opening of each flue being equal to the length of the upper opening of the wick-' space B between, while the lower ends of the air fines A A open on the outside of the wick-chamber B, and the latter extends down ports the whole, as seen in Fig. 3, so that it will open into the bowl of the lamp to which it may be applied, the usual wick-adjusting device, b being applied so as to serve as a means of raising and lowering the wick.

The deflectors a a are cut out of thinmetal plate, bent into the curved forms and applied so as to project toward each other over the upper ends of the flues A A, as represented in the drawings-i. e.,.soas to present two plates curved toward each other and extending in length horizontally abonta quarter of an inch beyond the two opposite narrower sides of the two flues A A, and so as to leave a space, c of about three-sixteenths of an inch'wide be tween their approaching edges, the space between the flnes which forms the outlet for the wick b being about one-eighth of an inch wide and about a quarter of an inch below the up per edgesof the deflectors, substantially as seen in Figs. 2 and 3. a

In the operation of this burner, while th wick b conducts the oil up to its upper end, the upper ends of the fines A A, and the deflecting-plates a a become heated, and conse quently they warm the thin flat currents of I air which passin contact with them and dis charge it into the flame, thus affording a copious supply of warm air thereto, and effecting the combustion of the carbonaceous matter of the oil, so as to produce a large, bright, and smokeless flame,.substantially of the size and form indicated by the dotted linef in Fig. 1; and at the same time if the lamp be moved about, suddenly lifted, or otherwise subjected to currents of air, the deflectors aa will pre vent the extinguishment of the flame by directing the currents with 'the flame, either downward through one or both of the flues A A, or longitudinally along beneath the deflectors, as the direction of the approach of the draft of air may be. The wick-chamber'being roomy, the wick is not liable to be charred nor even heated below the flame.

The whole construction is believed to be more simple, cheap, and eflectivefor the purpose than any other bnrner in use for burning coal-oil without a chimney.

Having thus fully described my improved burner, and pointed out its utility, what I" other and the cap 0 substantially in the manclaim as new therein, of my invention, and dener described and set forth, for the purposes sire to secure by Letters Patent, isspecified.

The two distinct tapering air-flues A A, in GEO. L. WITSIL. combination with the two deflectors a a, and Witnesses:

the spacious wick-chamber B, the same being constructed and arranged in relation to each BENJ. MoRIsoN, JAMEs 1?. DIX.
