Beit known that I, THEODORE emcee, of

mental-in- Lamps for BurningHydrocarbon-Oils; and

cbrrectdcscripticm thereof, reference being had to the accompanying drawings, and to the letters of reference thereon. v

My invention relates to lamps wherein a gas-jetflame is produced in lamps that burn wicks, by means of a jet of air fi'om a jet-pipe or nozzle similar to'a bat-wing or fish-tail gas-burner, the jet of air underpressure being forced to mingle with the products of combustion from V a surrounding wick, as in Letters Patent oftheUnited States, granted to, me,.bea'1 i.ng date the 26th of No- 'In that patent, a form of construction is described and shown, adapted to'burn light hydrocarbomoils, and

which will also burn the-heavier oils, commonly called kerosene-oils. v I t ButI have-discovered-that, in burning the heavier oils in said lamps, the-wick becomes encrusted with solid matter arisingfrom the. combustion, and that such accumulations cause the lamp to smoke, unless trimmed oftener than is convenient in the use of lamps,

said invention, which consists in'combi'n'ing with the .aiajet pipe, two wick-tubes, which may be flat at their lowerends,'zu 1d also at the point of unionwith the lamp-cap,but which are curved, at the burning-point, in the form of segments of a circle, thetwo segments being placed oppositeeach other, with thejet-pipe be tween them, in the manner shown in the drawings, and so as to allow air to come in contact with the wicks at their side edges, the segmentsbeing separateda little- .l'rombach other for that purpose. 3
