bores, see Fig. 3, to Wit the bore 12 connect ed to the pipe and continued at right angles into the vessel 2; the bore 13 connected to the tube 9 and continued Without connection with the interior of the vessel 2 to second tube A, and the third here 15 which connects a vertical pipe 16 extending to the lJOtiOlli of the vessel 2 with a conduit 17,

F I l I I I I I I I I g I i I I I I I I I I I I comprising two thin flexible metallic tubes,

coiled about the tube The bores 12 and 15 can be closed by valves 18 end 19 respectively. v

The conduit 17 leads to the fuel pipe 20 of the burner, to which the vaporizer 21 consisting of it plurality of turns of the pipe is connected. A part of the burner pipe 20 and the greater part of the Vaporizer 21 are filled with a porous, incomlmstible material as shown in Fig. s. The part of the Vaporizer nearest the burner, however, is un filled. The veporizer is so arranged that the pipe 20 opens into it at the part which .is farthest i'en'ioved from the vaporizing flame. 4

Connected to the vaporizer is a pipe 22 Whose one branch 23 leads to the vaporizer burner, While its second branch 25 leads he hind the valve llfilelpOlHlEcl in the pipe 22. to thepipe 27 for the maintaining ihe combustion. This pipe 27 is connected to the tube 14. The *aporizer burner 24 is a Bunsen burner. The opening of its nozzle 28 can be iegulmed by the needle by means of the grip 30. The upper part 81 of the pipe i i' bent and carries the mouthpiece of the burner. To each burner belongs e series of exchangeable mouthpieces 32 of various bore.

The appiu'atus is manipulated as fol; lows-z -The redniifiing valve ls adjusted the pressure at Which 17.01 21 is heated by any Home, and then sill the valves 8, 15, 19. 26. and 29 are opened.

The vaporizer burner 24 and the mam blow )ipe 32 are then winter]. In order to admst the pressure of thefuel and gas to the mouthpiece 32 which is being used, the throttle valve 8 is adjusted as desired and-the valve 26 gradually opened until an excess of fuel is present which is known by the flame beginning to burn white. When the flame V rises at this moment from the mouthpiece 32 and goes out, the gas pressure is correct and the throttle valve 8 correctly set. This 10 adj ust-ment-is readily eflected by trial. When the correct as pressure is ascertained the valve 26 is c osed again a little to such an extent that the flame burns bluish green at the mouthpiece 32, whereby a powerfully reducing action of the flame with the maximum attainable performance is indicated.

The fuel is vaporized in the coils of the vaporizer 21 filled with a porous mass, the said mass preventing unvaporized liquid fuel issuing or the vaporization being irregular. The unfilled part of the vaporizer, which is highly heated in consequence of the proximity of the flame of. the vaporizer burner and on account of the previous heat- 25 ing of the fuel, acts as a superheater so that the fuel is completely dried in it and leaves it as gas.

We claim 1. In apparatus of the type described, the combination of a vessel for gas under pressure for maintaining combustion, a blow pipe, a receptacle for liquid fuel, a gas pipe fromthe said vessel leading into the said receptacle, means for leading gas from the said vessel-t0 the said blow pipe, .said blow I pipe comprising a vaporizer and a burner for heating the vaporizer, and means for conducting fuel from said receptacle to said vaporizer and burner. 2.
