Beit known that I, WILLIAM G. BIRD, a citizen of the United States, and a resident of Kansas City, Wyandotte county, Kansas, have invented certain new and useful Improvements in Hydrocarbon-Lamps, of which the following is a specification.

My invention relates to improvements in hydrocarbon-vapor-burning lamps for illuminating purposes, and especially tothe form, location, and construction of the vaporizingtube and mixing tube or chamber. l conduct the hydrocarbon from the tank or reservoir to a vaporizing-tube exposed to the heat of the burner of the lamp, in which tube said liquid is vaporized and from which it is projected in the form of a jet into a mixingtube and gas-supply tube leading from such mixing-'tube to the burner of the lamp. l provide novel mean's for dividing or distributing the liquid in the vaporizing-tube and an improved metal canopy or drum to be placed over the lamp-chimney, inclosing the terminal portion of the vaporizing-tube to secure greater concentration of heat upon said tube.

yIn the drawings, Figure 1 is an elevation of the lamp with all its 'parts in place. Fig. 2 is an enlarged view, partially in section, of the vaporizing-'tube and nozzle detached. Fig. 3 'is a detachedview of a polygonal" bar inserted within the bore ofthe vaporizing-tube. Said ligure also shows a section of said bar. Fig. 4 is a central longitudinal section of the adjustable mixing-tube. Fig. 5 isa detached view of a canopy or drum mounted over the burner and inclosing the bend of the Vaporizing-tube. Fig. 6 is an elevation, partiallyin section, of a double lamp constructed-on the same principle. p

. The lamp is provided with the usual elevated reservoir or tank l, from which depends the substantially-vertical supply-pipe 2, which extends downward to aT 3, having an opening at theA bottom, which is normally closed by a removable s'crew-plug4. The burner 5 is mounted on the lower end of a substantially U -shaped tubular bracket 6, consisting of an upper and lower portion connected by a union 7, which is attached to the T 3 by screwthreads or in any preferred manner, but has 110 internal communication with it.

The burner 5 is-ofan ordinary type of vapor-burner and is provided with the usual mantle 8 and glass chimney 9.

The vertical supply-pipe 2 is provided at a suitable point above the plane at the top of the lamp-chimney with a T 10, from which extends laterally toward the lamp the vaporizing-tubevll, the admission of the liquid to which is controlled by a valve 12. Said vaporizing-tube 11 is provided at a pointimmediately over the burner 5 with a downwardlycurving gooseneck portion 13,which is threaded at its upper end into the tube 11 and at its lower end into a horizontally-disposed nozzl'e 14, lying in the vertical plane of the tube 11 and burner 5 and having a gas-orifice 14 at its outer end. The tubularbracket 6 forms the supply tube for supplying gas to the burner, and its upper end is curved toward 'and terminates immediately opposite and in alinement with the nozzle 14, so that gas issuing from said nozzle will be projected directly into the tube 6.

The vaporiz'ing-tube 11, as shown in Figs. 2

and 3, is provided with a removable polygonal` bar or core 15, which is inserted within the bore of said tube, with its angles preferably in contact with the inner walls of the tube. The function of said bar is to divide the stream of hydrocarbon coming from the reservoir and passing through said tube, the liquid passing through the spaces between the sides of the bar and the walls of the tube, thereby greatly promoting and expediting vaporzation. Said bar 15 is shown hexagonal in the drawings; but it is obvious that it may have any preferred number of angles. An-

other advantage of this construction of the vaporizing-tube is the great convenience of cleaning it, the bar being easily removablefor that purpose.

The gooseneck portion 13 of the tubewhen in operation is inclosed within an adjustable removable cylindricaldrumv 'or canopyfklG, open at its top and bottom and mounted on said gooseneck above the burner and inclosing at its lower end the top of the chimney. Said drum is made in two parts or sections 17 18, Fig. 1, pivoted togetherat 19 and provided with notches 20 2l, cut in their edges upon one side of the drum, the upper ones IOO 2O adapted to fit over and inclose the tube 11 and the lower ones 21 to engage an annular groove 22 in the nozzle 14, making tight joints. The effect of this construction is in opg-ation Y to subject the gooseneck 13 to intense heat, which heat is also conducted to the tube 11 and bar l therein, eifectually vaporizing all the hydrocarbon passing through ysaid tube. The hydrostatic pressure on the liquid in pipe 2 and tube 11 causes the hydrocarbon gas to be projected from the nozzle 14 into the upper end of the gas-supply tube 6, lead-n ing to the burner 5. Y On the .upper end of said 1ast-mentioned -tube is mounted an ad2er j ustable mixing-tube 23,- (shown insection in Fig. 4,) which tsover the end of tube 6 and is movable thereon. It is somewhat reduced in size at its other end, so as to fit over the end of nozzle 14, and openings 24 are provided in the walls of the mixing-tube. The

function of the mixing-tube 23 is to provide means of mixing a suitable quantity of oxygen from the air with the jet of hydrocarbon' gas rissuing fromnozzle 14. If the tube is made to engageV both the supply-pipe 6 and the nozzle 14, as seen on the right-hand side of Fig. 6, the amount of oxygen passing into tubes 23 and 6 will be limited to what enters through the openings 24; but if said tube 23 is disengaged from .the nozzle the amount of oxygen mixing with the hydrocarbon vapor in the tube will be largely increased. The tube 23 therefore furnishes means for combining such an. amount of oxygen with the vapor as will secure the best practical results at the burner.

The operation has been substantially indicated. The initial heat is obtained, preferably, by applying an alcohol-torch to the `gooseneck 13, within the drum 16. As soon as said gooseneck and tube 11 are suiiiciently heated the hydrocarbon is admitted through the valve 12, becomes vaporized, as described, and passes from nozzle 14 through the mix- `ing-.tube 23 into supply-tube 6 and thence to the burner 5, where it is lighted as soon as the ilow lof gas is established. The torch .may then be removed, and thereafter the burner furnishes the heat n-ecessa y for vaporizingv the hydrocarbon. Y p

The extension 2a of pipe 2 and the chamber in the T 3 furnish yareservoir or trap for -the accumulation of any sediment or impurities contained in the hydrocarbon. Instead of passing into the vaporizing-tube 11 such matters naturally settleby gravitation into pipe 2 and said chamber. By occasionally removing the plug 4 and allowing the liquid from the tank to pass out of the opening said pipe and chamber may be thoroughly flushed.

. Fig. '6 shows the same construction applied to a double lamp, tion. Y

It will be further observed that in the bore of the horizontally-disposed nozzle 14 Ihave but needs no special descripadapted to arrest atoms of dust or other impurities from passing to the supply-tube 6 with the newly-generated gases.
