An operating wheel 206 is fastened to one end of the shaft-204. A brick lining 210 encircles the shells 16 and 84.4

To operate the vapor extractor, shale, cannel coal or similar materials are deposited into the funnel shaped preheating hopper h192, the grate 198-of which has been previously moved to its closed position. At this time the nozzle 188 has been located to one side of the outlet nozzle 193, and thereby any small particles of shale or other material that may have'pas'sed between the bars of the grate 198 are separated from the charge in `the hopper 192 and disposed of. Next the upper door of the generating chamber 15 is fully opened. The operator now swings the funnel 189 in line with and under the outlet nozzle 193 and also in line with and over the opening 18 in the roof 17 of the gen- `are turned to close the ports 1113 in the valve casings D.

rl`he door 42 is next tightly closed.` rl`he tunnel 189 is now swung from and out of line with the outlet nozzle 193, to locate the nozzle 188 in line with said nozzle 193. The

A funnel shaped preheating hopper 192 hasy nozzle 188 is now fastened to the nozzle 193.

lThe upper door 70 isnext closed and the grate 198 is moved to its closed posit-ion and another charge of material is placed in the preheating hopper 192. Both the

fan wheels

90 and 184 are started, by means of their respective motors and a circulation of cold air "is first established through the charge in the generating chamber 15 and in the hopper 192. Cold air is drawn by means of the fan wheel 90 from the generating chamber 15 through the cylindrical portion 66 of the mouth piece. the outlet nozzle 67 thence to the fan casing 89, and from the latter it is forced through the inlet conduit 88 and then into the heating chamber 85.

- The air next -fiows downwardly between the heating tubes A, through the opening 83 into the shell 16 at the` lower end of the generating chamber 15.\ rlhe air next flows through the openings in -the grates B, C and 1.74, and thence through the charge in the generating chamber.

The gas of the burners is next turned on and the gas mixture owing from the Bun- `sen gas outlet tips 126 is lit. The tan wheel 90 continues to draw the air, which is now being heated, from the generating chamber 15 and forces it into the inlet conduit 88 and from thence into the heating chamber 85 on the outside of the heating tubes and by virtue of which the air is heated each time that it flows through the chamber 85. The heated air flows from the chamber. 85, through the opening 83 into the generating chamber 15 under the grates B, C and 174. The heated air in owing upwardly through the charge in the chamber 15 imparts its heat thereto. By this means vapor` and gases are generated from the 'charge in the chamber 15 and displaces the air which has previously been used for circulation and transmission ofi'heat in the charge of .material. This cycle of operations with the heated air and the gases and vapors generated continues until thepr'essure of said vapors and gases rise above atmospheric pressure, when they escape through the vapor outlet piping 76. rlihe escaping vapors may be led to a condenser to liquifv them whereby the uncondensible gases are separated and led into a holder'and provide fuel i for the burners of the apparatus. The charge in the chamber 15 is heated until no more vapors and gases emanate therefrom. During the operation of the burners the products of combustion thereof rise, twirl in the heating tubes A and are drawn into the waste gas outlet nozzle 1,80. by virtue of the suction effect of the fan wheel 184i.. and are forced through the nozzle 188, then between the bars of the grate 198 and through the charge of material in the preheating hopper 192. During the continuation of the runs of the extractor the charge, that is when discharged from the latter.

located in the generating chamber 15, has

previously been preheated in the hopper 192, thereby utilizing the products of combustion of the burners of the extractor.

To empty the generating chamber 15 the gas supply is first cut 'ofi' and both the

fan wheels

90 and 184 are stopped. rl`hen the lower door 42 is swung open, and the grates B and@ are opened by means of the hydraulic cylinders 156, and the connecting chains 173 which latter are connected to the eyelets 137, the cylindrical valvev 145 having been turned to locate the port 146 in register with the port 143. The releasing bar 175 is next forced down and its lower end drops to the bottom 23 of the generating chamber 15, releasing said bar from the charge therein. The charge within generating chamber 15 being hot and expanded will be released and drop from said generating chamber 15 by'virtue of the gap left therein when displacing the bar 17 5. Next the lower door 42 is swung toits closed position and fastened in place. The triangular releasing bar 175 is now held in place in its upper position and the grates B and C are moved to their closed position by the hydraulic cylinder 156 and the bar 17 5 is supported on the grate C. The upper door 70 is next fully opened and the nozzle 188 is detached from the outlet nozzle 193 and swung aside to bring the funnel 189 under the outlet nozzle 193. Next the upper grate 198 is opened and the reheated charge in the hopper 192 drops into the generating chamber 15. rl'he upper grate 198 is moved to its closed position,'and the upper door 70 is closed and tightenedin place. A new charge of material is now dumped into the hopper 192, and after the small particles of 'the charge drop through the grate 198 and the funnel 189, the nozzle 188 is fastened to the nozzle 193, and the operations are continued. The fan wheels are preferably stopped when the charge from the hopper 192 is dumped into the chamber 15 and also The circulation through the connectingsuction conduit 97 and its rapidity is indicated by means of the small'indicating disc 104 of the shaft 101 that carries the indicating propeller 100.
