The upper portion of the cylinder of the scouring apparatus is provided with a second grating 22- between which and the adjacent head of said cylinder is a second body of dry filter material such as coal,

I a

An important feature of our invention,

in connection \vlth the other features of thesteam generator just described is the arrangement of water supply thereto. The water distribution system comprises a feedpipe 30 which delivers water under pressure to the gas generator water jacket 25,

and

where it serves as a cooling medium, from said water jacket a lead pipe 30 is connected to a spray head 31 that is located within the scouring apparatus whereby water is admitted to the scouring material 23. This lead pipe has a branch 30 with a pin valve 32,-the nozzle of which is incased m a sight-feed housing 33 and adapted to discharge into the mouth of a pipe section 30", the mouth of the same being. also incased withinthe housing. The lower end of the pipe section is-coupled to the top leg of'the steam generator pipe 29 as shown, and by the above fitting it will be seen that said steam generator is entirely closed from theatmosphei'e except at. its lower point of discharge, the. back pressure of the generated steam upon the small jet of water being practically unappreciable- Hence -by proper manipulation of the pinvalve water t-em can be instantly converted into a highly expansible dry steam for immediate consurn tion, resulting in great efficiency in the pro uction of a commercial water gas.

In the initial operation of our gas generating apparatus the fresh fire in the fuel pot is supplied by air only throu' h the valve-controlled. pipe 11, the pin-Va ve 32' which supplies water to the steam generator being closed. The initial gases therefore will pass from the gas pocket 12, through. the-fines and bonnet 14 and from thence to atmosphere through the vent-pipe 21 to the stack 21. After the fuel has reached delivered from the closed sysioo the desired temperature, valve 18 in the drain pipe 18 is closed, whereby the water from the scouring apparatus will rise within the trap and thus cut off communication of the gases, with the atmosphere through vent-pipe 21,-.which pipe is thus sealed. The

water seal thereafter will be maintained at the level of the overflow branch-pipe 18" of the drain. The pin-valve-13 of the water-' supply system is now opened to permit a jet of. water tov flow into the coiled pipe 29. The said pipe being previously heated by the gases passing there- -over, will mstantlygenerate steam which is discharged into the air-chamber 9 and after commi moist air will be drawn into the fire pot and up through the body of fuel, whereby steam generator ngling with the air therein said moisture and oxygen are added in the proper proportions to produce an etiicient gas, This gas passes over the mouth of the'fire pot into the gas pocket 1 in equal and even quantities throughout the full circular area of said fuel pot and thereafter the gas travels through the flue l3 and the heating drum 1% to the scouring apparatus, in a direct line through the hood l t to the lower end of said scouring apparatus. The gases thereafter pass up through said scouring apparatus and are delivered to the source of consumption or storage in the usual manner, it being understood that the pipe 24 of the scrubbing cylinder is under suitablbe valve control not shown, whereby the gas during an initial operation is prevented from passing therethrough.

Particular attention is called to the steam generating and air mixing apparatus operating in conjunction with an unobstructed open mouth fuel pot, which. is rendered practical, owing to the fact that the gener ator head is provided with a Water cooled jacket, another essential feature of the invention being the arrangement whereby a valve, in the form of a water-seal, is utilized for controlling the gases, the elasticity of which valve renders it possible to avoid accidents due to explosion of the gases in which case the water seal will readily yield to the force,

Another important feature of our invention in connection with the air and steam supply to the generator, is that by said arrangement, the ash-pit cleanout doors can be opened without interfering with the uniform operation of the apparatus. hen it is desirable to clean out the aslrpit, the. air supply pipe valve is closed and the draft of air admitted through the open door will be met by the steam supply from the chamber in a circular sheet, and the steam laden air will thus be drawn up throughthe bed of coals in a similar manner to that previously described in connection with the supply from pipe 11, there being no appreciable difference in the operation, Whether the air supply is delivered through the feed pipe 11 or ash-door opening, it being understood that the temperature of the steam in the chamber will cause the'rush of air through said door to be initially drawn toward the discharge mouth of said chamber where it meets the sheet of steam that is discharged therefrom.

\Ve claim:

In a gas producer having a jacket, a head ,closure therefor, an oilset shell secured to the jacket adjacent to its head to form a gas pocket, the shell being extended parallel with the jacket and having an open lower end formingin conjunction with said jacket an air chamber, an air supply pipe in com munication with the upper end of the air chamber, and a gas discharge pipe in communication with the gas-pocket; the combination of a perforated baffle-ring interposed betwccn the jacket and shell below the air supply pipe, :1 second perforated battlering interposed between the acket and shell at the lower end of said shell, layers of refractory material fitted within the shell to form a fire-pot, and a steam supply pipe having a branch in communication with the air chamberabove the lower battle-ring and a second branch pipe in communication with the fire-pot below said balilc-ring.

In testimony that we claim the foregoing We have hereunto set our hands at Milwaukee in the county of ll'lilwaulrcc and State of lVisco nsin in the presence of two witnesses.
