- u l'. v f" .froin'the frame l` andv tube l-byineans of'a plug or section 1 7' of comparatively low heat conductivitty which is interposed .between a cap -'18 screwed onto the threaded nipple v19 or'4 the end of the tube 12. The nipple v19 fand tube '12 are each provided with internal conicalv shoulders 20 opposed to siinilar shoulders 21 on theI caps 1S forinedby aper- Vtures 22 extending throughthe ei'id of the caps. The sections 1T are each provided with conical shoulders which, when the caps 1S are iriiily screwed up. engage the shoulders 2O and 21 whereby the sections are rigidly held iii place.` The sections 1T are each provided with a threaded aperture 23 adapted to receive the threaded end or nipple 2l formed on the generators 2 an'd l, whereby.-

they. are held in position.

.4 In the hydrocarbon lanip of the usual construction. the supporting fraine through which the fuel is being conveyed and `to which the generator is connected. often bel coiiies heated to such an extent as to cause vaporization of the fuel therein'in advance of the generator. Such vaporization of the fuel causes a back pressure on the liquid vfuel flowing to the generator thereby resulting in an unequal delivery of fuel to the generator and producing Va fluctuating light. This 4fault is overcoine in the present construction by the use of the sections 1T for .insulating the generator from the supporting frame.

The operation of the Adevice shown in the .drawings is as follows: If the lainp is used as shown in Fig. 1,A it will,-o f course. be

Anecessary to prelieat one or the other ofthe generators in order to start the lainp the Aiirstftiine, which may be accomplished by the use of any suitable torchf-such, for eX- aniple, as torch 25 shown in Fig. 2. After the lamp isonce started, the valve 14 is -usual needle valve operated by the handle 5b, which is adjusted to maintaina `constant flame directed onto the main generator 2 to keep it heated so that th'elamp is always ready for instantuse. During the burning of the lamp, the generator 2 is, of course, kept heated by the heat rising. from the y flame of the burners@ as to cause. the con- 'p without 4 burner, the supply of fuel thereto may be cut.l off by the valve 1 4, and the generatorv stant generation of gas, the'tlow of which into the mixer T is controlled by the needle valve 9. If it is desired to use the lamp the pilot-light generator land and `burner detached from the tube 1-2 without disturbing any other part ofthe lamp,

whereupon 'the lamp appears as shown in' F ig. 2. 'hen so used, it is necessary to preheat the generator each time before starting thelamp. This may be done b v using a torch comprising a swab 2.5 secured to a wire'26 adapted to be hung over the generator in the position shown in dotted outline in Fig. :'2. After the swab :25 has been saturatedwith alcohol or gasolene, it

' may be ignited and the generator heated to a temperature sufficient to vcommence the vaporization ofthe fuel therein for the starting ofthe lamp. The 'insulating'of the generators 2 and 4 from the frame 1l prevents heating of the frame 1 and thereby avoids .any1 vaporization of the fuel 1n advance vof its ldelivery tovthe generators, so

that the gas is generated only bythe generators anda steadv delivery. thereof to the mixer is obtained, 1resulting yin av steady light.

this invention is herein shown and described, it will be understood. that numerous details of thel constructionv shown may be altered.`

Iclaim:- y A hydrocarbon lamp comprising a frame having a fuel inletchannel, a generatorl and burner connected with. said frame and.

communicating with said fuel inlet channel, and a section fof'materlal of comparativelvtT low heat conductivity interposed between' the connection of said burner and frame,so

as to vinsulate said Vgenerator l from said frame.
