To all wkomz't may concern.'

, ,Be it Aknown that I, GEORGE H. Roms, a citizen of the United States of America, a resident of theacity of'St. Iiouis, in the State of Missouri, have invented certain new and useful Improvements in VLantern-Bunners, of which the followingfis afull, clear,

and exact description, reference being had' to the "accompanying drawings, forming a part of this specification.

AMy vinvention relatestoa burner intended for use more especially in railway hand lanterns which are subjected to severe motion in giving signals. The invention has for its object the production of a flame spreading" burner for a lantern of this kind so formed as to avoid extinction of the liame, due to currents of air entering the lantern. The flame spreader surrounds and surmounts the upper end of the wick tube, with provision therein for the entrance of air to supply oxygen to a flame burning from the wick and means for so protecting the air entranceways as to avoid movement of airtherethrough with sufficient force to interfere. with the burning of the ame.

Figure I is a top view of my burner in position upon a lantern font.

Fig. II is a side elevation of the lamp font, the burner being partly in elevation and partly in vertical longitudinal section.

Fig. III is an elevation of the upper portion of the lamp font, the burner being partly in elevation and partly in cross section. Y

In the drawings A designates a lamp font of any ordinary form and B a burner fitted to said font. The burner includes a wick tube b within which is a wick C, preferably, though not' necessarily, circular in cross section.

At the upper end of the wick tube of my burner is a cup-shaped flame spreader D, which comprises a bottom member l secured to the tube, end walls 2 and side walls 3, the side walls being preferably longer than the end walls, thereby rendering the cup-shaped spreader of elongated shape. InV the side y walls of the spreader are apertures 4, prefera-bly of semi-circular shape, the apertures terminating in proximity to the top edges of said side walls and having their curved edges extending downwardly to points near the bottomv of the spreader. The apertures 4 serve to admit airr to the interior of the `LAIITEIan-BURLTEYR.

spreader D in `a lateral directionthrough its side walls lto Asupply .the necessaryfoxygen for the supportof combustion immediately above the wick of the burner, notwithstandingith'e` fact that the wick terminates at the bgttom of the spreader, which extends there-'- a ove.. f f

The spreader-l) acts to' spread :the"flan1e,v

due to its extension above the'height oftheA upper end of the burner wick, the flame being drawn tothe walls Qfandf of the spreader, thereby enhancing thek illuminatair may pass beneath them and then upwardly tov enter the interior of the flame spreader through the apertures 4. The baflie wings, flaring outwardly from the top of the flame spreader as described, preferably extend downwardly to a horizontal line through the burner at a lower level than the bottoms of the apertures 4, and consequently there is no opportunity for strong currents of air to pass in a horizontal course through the apertures 4, but, Von the contrary, all airy entering the spreader through said,V apertures must move in an upward course' as it passes beneath the baffle-wings, and such air, by passage inan upward course, assists materially not only in supplying oxygen to the burner flame but also in maintaining a steady flame. A

While I have described my burner as intended more especially for use in lanterns,

such quantity as to interfere with the proper v burning of the Vflame within the ame spreader. For thepurpose of stabilizing the baiie wings 5 so that they will not be bent from their proper inclined positions, relative to the side walls of the flame spreader, I provide each balile wing with a supporting leg 5a suitably secured to the lower portion of the burner.

I claim:

l. A burner of the character described comprising a wick tube, and a cup-shaped fiame spreader secured to said wick tube, said llame spreader having walls provided with apertures and baille wings flaring downwardly and outwardly from the upper portions of the apertured walls.

2. A burner of the character described comprising awick tube and a cup-shaped flame spreader secured to said tube, the walls of said spreader having apertL1res-tlierein and having secured thereto flaring baille wings which extend downwardly from the upper portions of said walls to points beneath the lower edges of the apertures.

3. A burner of the character described comprising a wick tube and a cup-shaped flame spreader secured t0 said tube., the walls of' said spreader having apertures of semi-circular shape therein and baille wings flaring outwardly and downwardly from the upper portions .of Vthe apertured walls.

4. A burner of the character described comprising a wick tube, and a cup-shaped flame spreader secured to said 'wick' tube, said flame spreader having walls provided with apertures and perforated loailie wings flaring downwardly and outwardly from the upper portions of the apertured walls.

In testimony that I claim the foregoingl hereunto affix my signature.
