To all whom it may concern:

Be it known that I, LEoPonn F. BURGER, a citizen of the United States, residing at Beloit, in the county of Rock and State of Wisconsin, have invented. certainnew and useful Improvements in Gas-Producers, of

which the following is a full, clear, andeXact specification, I .Th1s invention relates to gas producers and more particularly to down draft gas producers of the class in which air, or air and steam, is directed into a fuel chamber for the purpose'of supporting incandescent combustion therein, theresulting gas being drawn ofi by means of suction from an engine, or otherwise. v v y A disadvantage peculiar to down draft producers is that of the arrangementon the top, of the generator of the twyer and fuel hopper or charger. Central positions for both of these parts are desirable in order to produce the best results in the operation of the producer, and separate openings must be provided for both in order to prevent foreign particles from passing into the twyer or air pipes communicating therewith, when fuel is placed in-the charger. My 'object, therefore,'is to simplify and improve the twyer and fuel hopper or ch arge arrangement.

A further object-1s to obtain greater efliciency in the operation of a device of this class by providing for a uniform distribu- Y tion of theair and steam mto the fuel, and

this I accomplish by providing a central location on the generatingchamber for the twyer. A further object is to increase the gas-inaking properties of the fuel, which is accomplished by the provision of means for controlling the proportionate amount of air and steam as the same are delivered to the fuelvchamber of vthe producer.

become readily apparent from the following detailed description ofone form of my invention illustrated in the accompanying drawings, in which The single figure shows a vertical central sectional view of a gas producer embodying my invention.

Similar numerals refer to corresponding parts throughout the se e al views.

I In the drawings, the gas producer comprises a generating chamber 10 formedof a shell portlon 11 prov dedwith a lining 12 of fire brick or other refractory material; a?

bosh 13 arranged at the bottomof the generating chamber and provided on its periphery Witll'fivaporizing chamber 14; a hearth portion 15 formed below the generating" =chamber and mounted within a supporting basin 16, said supporting basin having formed within a ,chamber 17 designed to contain water for sealing the lower end of having its upper end terminating a short distance above the lower end of the bosh 13. A top plate 19 is provided for the upper end of the generating chamber and superimposed thereon is a water chamber '20 from which water may be conveyed to the vaporizing chamber 14 in any suitable manner. is a twyer 21 extending upwardly and provided, at its upper end with a removable cover 22. A fuel charger 23 is carried within the twyerwvith its sides spaced apart therefrom to. form an annular chamber 24:.

A flange 25 on the upper end of the fuel charger, resting on a shoulder 26 formed on the twyer, is employed for supporting said fuel charger in position within the twyer.

An air and steam pipe :27 adapted to communicatewith the side of the twyer, with the "aporizing chamber and with the hearth portion, is arranged at one side of the producer and is provided with a blower 28 of ordinary construction. A slidable valve 29 is employed for controlling communication between the blower and twyer. A similar valve 30 controls communication between the blower and vaporizer and a like valvev ber and a butterfly valve 33 is employed therein for regulating the admission of air to said vaporizing chamber. A vent pipe 34 is arranged on top of the generator chamher with its upper end open to the exterior atmosphere, and a slidable valve 35 is pro;

vided in said pipe for controlling communi- Centrally arranged on the top plate cation with th; interior of the generating chamber. A. gas outlet pipe 36 is arranged on the hearth portion of the producer.

The operation of the producer is as follows: Fuel is supplied to the generating chamber through the charger 23, and is 'ig nited in the hearth portion 15. To obtain initial combustion of the fuel, the valve 35 in the vent pipe 3% is opened and communica tion with the exterior atmosphere is established for the generating chamber. The valves 29 and in the air pipe 27 are closed and the valve 31 in said. pipe is opened and the blower 28 is put in, operation for supplying a draft to the hearth portion of the producer. Obviously, with the upper end of the generating chamber communicating with the outside by means of the vent pipe Bl, the current supplied by the blower will move upwardly and the products of combustion will be carried off by said pipe.

Assuming that afuel is being used in theproducer which burns readily or is light in form, such as shavlngs or cobs, and the fire has been properly started but has not yet reached the desired degree of intensity for making gas, then in order to prevent unnecessary consumption of the fuel or waste thereof through the vent pipe, the direction of the draft is reversed in the following manner:

The valve in the vent pipe and the slidable valve 31 in the air pipe are closed and the valve 29 is opened, and thereupon the blower 28 is operated and the draft therefrom is admitted into the generating chamber through the twyer at the top thereof. Sufficient air is admitted in this way to intensify the fire until it has reached an incandescentstage. The products of combustion during this operation pass through the gas outlet pipe 36.

When the fire has reached the proper degree of heat in the producer for making gas suitable for usage, the operation of the blower 28 is discontinued and the engine or other means used for creating suction in the producer is started. The suction created in the hearth portion through the gas outlet pipe will draw steam and air from the vaporizer 14 upwardly through the pipe 27 and into the generating chamber through the twyer 21. Incandescent combustion of the fuel is supported in this manner and the gas resulting therefrom is carried off by the pipe 36. hen it is desired to discontinue the operation of the producer, the valve 35 in the vent pipe as is opened to permit the products of combustion in the generating chamber to pass ed. 7

It will be seen from the arrangement of the twyer and fuel charger that I have obtained a central location for both of these parts and thereby the fuel is evenly dis tributed within thegenerating chamber, as are also the air and steam that are admitted through the twyer. By thus locating the twyer centrally on the top of the generating chamber a uniform burning of the fuel results. The method of connecting the pipe 27 with the side of the twyer obviously prevents any and all possibility of fuel passing into said pipe when the generator is being charged with fuel.

lVhile I have shown and described but one form of my device, it will, nevertheless, be understood that it is capable of many m0di fications and that changes may be resorted to without departing from the spirit of my in vention, as disclosed in the appended claims.

lVhat I claim as my invention and desire to secure by Letters Patent is:

1. In a gas producer, the combination of a generating chamber, a fuel charger arranged at thetop of the generating chamber, a twyer surrounding said fuel charger, and a vaporizing chamber connected to said twy'er.

2. In a gas producer, a generatingchamher, a fuel charger on said generating chamber, a twyer on said chamber for admitting combustion supporter, said charger and twyer both occupying central position thereon, and a vaporizing chamber connected to said twyer. v

3. In a gas producer, a generating chamher, a fuel charger centrally arranged on said chamber, a twyer surrounding said fuel charger, and a vaporizing chamber connected to said twyer.

4. In a gas producer, the combination of a generating chamber, a twyer centrally arranged on the top thereof, a fuel charger arranged within said twyer and spaced apart from the sides thereof, and an air and steam pipe arranged on the side of said twyer and communicating with the interior thereof.-

In testimony whereof I atiiX my signature, in the presence of two witnesses.
