I GAS-PRODUCER. l

SPECIFlCATION forming part of Letters Patent No. 762,568, dated June 14, 1904. Application ld f imary 6, 1904. Serial No. 187,937. (No model.)

To all whom it may concern:

Be it known thatI, LIDA WILSON, acitizen of the United States of America, Whose present address is 55 West Regent street, Glasgow, Scotland, have invented acertain new and useful Improvement in Gas-Producers, of which the following is a specification.

This invention relates to gas-producers, and has for its object the production of gas of varying composition, illuminating andv thermal power, at the will of the operator, and the utilization of the heat resulting `from the con-A sumption of fuel in order to produce the steam required and to superheat it and thefair employed to produce the gas.

In the ordinary method of producing watergas it is necessary to work alternately, at one stage taking off the gas for use, and when the fuel in the producer hasbecome reduced in temperature by the steam blowing up the producer with air to promote combustion and` revive the heat of the fuel, the gases produced at thisstage being permitted to pass away to the atmosphere, thereby wasting fuel, losing gas, 'and causing intermittent production of gas for use. My improvements avoid this and permit constant production of gas suitable for use and ready control of its thermal and illuminating power during its production.

Figure l-is a vertical section through my improved gas-producer. Fig. 2Jis a plan of the same-with top plate aud hopper removed.

A is an inner casing, andA' is an outer casing, the former at its lower portion being lined with {ire-brick or suitable he'at refractory materialI B and the latterbein'g`lined with tiregrate under the said central chamber, uponl which grate the remay be first lighted and brick or suitable heat refractory material B throughout its length.- The complete double casing is closed with a cover C, having a hopper C for theV admission or feed of fuel into the central chamber of the producer. D is a towhich accesscan be obtained through'a `door G, through which the ashes may be removed. Betweenthe outer casing A' andtheA inner casing A the air for su ppo'rting the combustion uponthe grate D and in the body of fuel The steam, or water to produce the steam,

which it is desired to pass through the incandescent fuel is introduced by the pipe H atl suitable pressure, Which-pipe is arranged between .the different turns of the pipe F or Ain other convenient manner within the space between the casings Aand A'. The air, water, yor steam may also be arranged to pass through one common pipe, the respective inlets thereto being duly controlled. by separate valves.` The contents of' these pipes H and F, which are controlled by cocks .or valves- H F', respectively, are so heated by radiation from the fuel inthe central chamber ofthe producer and also bythe gas issuing from the outlets E, leading therefrom that water supplied through the pipe H becomes dry steam or steam introduced therethrough,' las well as the air introduced through ,the pipe F becomes highly superheated before admission to the fuel in the central chamber of the producer. The gas passes off through the outlets E and the upper fines M and L, one of which-conducts the gas away for use and the other is available for discharge of gases to the atmos phere Vwhen the fire is first lighted and when it is not desired to collect the gas produced. The pipes -M and are controlled by suitable valves i L for this purpose, and the outiiow of gas may be assisted by suction applied in any convenient manner. y

A pipe K, having a suitable control-valve K andfpierced with numerous holes, is introduced near the top of the central compartment of the producer, whereby liquid or gaseous hydrocar-bons may be applied to the fuel inthe producer, their vapors passing down through the fuel until they reach the aforesaid side outlets E, before reaching which point the great heat of the fuel 'in the central chamber converts the -hydrocarbons into permanent gas.

By suitably adjusting the supply of the respective quantities of fuel, air. water or steam, and hydrocarbon continuo-us working or production of gas for use may be maintained without intermittent blowing up, and the quality of the resulting gas as to thermal and illuminating power may be' controlled at the will of the operator. The quality of the gas may be ascertained by test-jets, as usual.

The outlet-apertures E, leading from the central chamber of the producer to the sur rounding compartment, have doors N in the outer casing for their inspection, cleaning, or

access.

The dust carried over by the gas through the outlets E tends to deposit as the gas rises, baflied by the pipes H and F, against which it impacts. The dust so deposited collects in the bottom of the space between the inner and outer casings, as at P, and doors 0 O are provided for its removal as it accumulates. Thus the gases after leaving this producer may be used Awithout further purification; but, if desired', they may be cooled, washed, and filtered through scrubbers in the usual well-known manner. 4

Having now described my invention, what L claim, and desire to secure'by Letters Patent, is-

In combination in a gas-producer, a central compartment for the combustion of fuel, a heat refractory lining surrounding the lower part thereof, a surrounding compartment, provided with a heat refractory lining, and forming an intervening space between such lining and the casing of the central compartment, a lateral exit for the gas from the said central compartment," intermediate of its height, communicating with said intervening space, a duplicate coil of pipes for the supply to the producer, of heated air, and of superheated water or steam arranged in said space surrounding the central compartment, and means connected to the top of the space between the compartments for taking od the gases. substantially as described. l

In witness whereof I have hereuntol set my hand in presence of two witnesses.

LIDA WILSON.
