SPECIFICATION forming part of Letters Patent N0. 669,989, dated March 19, 1901.

The device by which the oil is vaporized The tube l5, instead of extending up to and 85 and burned is in its general construction joining the outer tube 20 of the double champreferably the same as that shown and deber, as in the construction shown in my apscribed in the application for Letters Patent plie-ation before referred to, terminates at a filed by me on the 27th day of October, 1900, point slightly below the upper end of the oil- Serial No. 34,531, and comprises an oil-chamchamber. The double chamber is supported 9o ber 1, to which oil is supplied under pressure, by the tube 27, the outer tube of the chama double chamber above the oil-chamber, ber being` preferably made, as shown, of a 4o comprising an outer tube 2O and an inner or size to fit within the upper end of tube 27.

In order to delivering gas from the mixing-tube into the hold this pipe rmly in position, the tube 27 space surrounding the base of the mixingis preferably provided with a reinforcingtube, an obstruction 25 to deflect a portion of ring 31 of sufficient thickness t0 have screwroo the gas from the mixing-tube into the downthreads cut therein to receive the screwtake-passage, a burner above the double threads formed on the end of the pipe. At

5o chamber, and air-inlet'passages 16 for admitits outer end the pipe 30 is provided with a ting air from below about the upper portion coupling 32, by which it may be connected to of the oil-chamber. a gasservice pipe 33. The pipe 3e may be :o5

The oil-chamber 1, as in the application rethe terminal of an ordinary gas-fixture. The

connecting-pipe 30 is made sufficiently strong and in its connection to the tube 27 sufficiently rigid to permit the whole device to be supported from the gas-Fixture, in which case the oil-supply tube 35 will be led'along the gas-pipe from a suitable tank containing oil under pressure.

If the device is to be used as a table light, it should be provided with a suitable base, and the may be supplied from any convenient fixture by aflexible tube, the oil being supplied from a tank on or beneath the table.

The device, as shown, being secured to a gas-supply pipe and the gas turned on, the gas will pass through the pipe 31 into the space between the outer tube 27 and tube l5 and up through the mixing-tube 21 to the burner. Air will enter through the passages 16 and the air-inlet 23 and mix with the gas. A portion ofthe mixed gas and air Will be deflected by the obstruction 25 into the downtake-passage and when ignited will be caused to form a cone of flame by the draft of air 'from the passages 16 within the base of the mixing-tube. The main portion ofthe mixed gas and air will pass through the obstruction 25 to the burner, Where it will be ignited and will heat the mantle to incandescence. The gas passing through the cone of liame will be highly heated and will more readily mix with the air entering through the air-inlet and will heat the mantle more satisfactorily than in the burners in which the gas is not thus heated. As soon as the cone of flame is formed the outlet-valve of the oil-chamber may be opened. rlhe oil discharged is vaporized in its passage through the cone of iiame and mixing` with the air entering through the airinlet 23 and with the gas will form very rich gas, by which the mantle Will be heated to a m uch more brilliant incandescence than could be secured without the addition ot' oil-vapor. When the vaporization of the oil is once begun, the gas-supply may be cutoff and the device run as a vapor-burner.

By closing the outlet-valve of the oil-chamloer and regulating the gas-supply a low light may be kept burning, as desired, it being neeessary only when a stronger light is desired to turn on the gas for an instant and open the outlet-valve of the oil-chamber.

By thus combining in one device a gas and Vapor burner I provide a light which can be regulated between wide limits from thelowest light possible with a gas incandescent light to the most powerful light possible from a vapor-burner.

While my invention has been described as a light, it should be understood that it may be used for general heating purposes, the article to be heated being placed above the burner in place of the mantle. The gas produced in the mixing-tube may, if desired, be used in a gas-engine or for any purpose for which a gaseous compound of vapor and air, such as is there formed, may be adapted.

By the use of my device a gas-supply of inferior quality may be enriched by the addition of oil-vapor, so that a light of great brilliance may be produced.
