GAs-rnonucnn FOR FURNACES.

Specification of Letters Patent.

Patented Aug. 3, 1915.

Application filed February 9, 1914. Serial No. 817,384.

To all whom it may concern:

Be it known that I, VVILLIAM O. HOUSTON, a citizen of the United States of America, and resident of Bellaire, county of Belmont, and State of Ohio, have invented certain new and useful Improvements in Gas-Producers for Furnaces, of which the following is a specification.

This invention relates broadly to furnaces, and specifically to a producer wherein gases are generated and directed to a combustion chamber.

The primary object of the invention is to provide a furnace of the gas-producer type which is of simple construction and which has a pair of fire-boxes arranged side by side, both in open communication with the combustion chamber, and which are separately fired, thus assuring a constant production of gas in such quantities as will prevent any serious reductions in the temperature of the heating chamber.

As is well known, when gas is furnished to the combustion chamber from a single fire-box, constant care must be exercised to keep the fuel bed in good gas-producing condition, and inattention frequently results in the fuel becoming packed and the fire smothered, retarding the production of gas to such an extent that the temperature of the heating chamber is materially lowered, ofttimes with seriously detrimental results, particularly in furnaces of a mufiie type wherein a substantially uniform temperature is required.

It is therefore the purpose of the present invention to provide a furnace whereby the above recited objection is obviated and the possibility of an undue lowering of the temperature is reduced to a minimum.

The invention resides in the features of construction, arrangement of parts and combination of elements which will hereinafter be fully described, reference being bad to the accompanying drawing, forming a part of this specification, in which- Figure 1 is a longitudinal section of the invention; and Fig. 2 is a view partially in front elevation and partially in transverse section on the line 2-2, Fig. 1.

Referring to said drawings, in which like designating characters distinguish like parts throughout the several.views1 1 indicate the opposite side-walls, 2 the rear end wall, and 3 the crown of a gas producer which is divided longitudinally by a central wall 4i to form two separate fire-boxes 5, both of which communicate through a passage 6 wlth a passage 7 leading to the combustion chamber (not shown). A set of grate-bars 8 provided in each fire-box supports the fuel-bed therefor, and said fire-boxes are fed separately, as from suitably arranged hoppers 9, or in any other suitable manner. Neither fire-box having any direct connection with the other, each must be attended separately, and each furnishes its quota of the gas required for maintaining the furnace at a proper high temperature. As will be understood, it is highly improbable that the fires in both fire-boxes would in any case become clogged or rendered inefficient at the same time. Thus, when the fire in one of said fire-boxes dies down from any cause, the other fire will be in condition to furnish a sufficient volume of gas to maintain a relatively high temperature in the heating chamber of the furnace, and will, particularlyif accelerated somewhat, supply gas in ample volume to maintain the required temperature until the fire in the one fire-box has been restored to proper condition.

Provided in the opposite side-walls 1, in the rear-end wall 2 and in the division wall 4 is a series of connected or communicating flues 10 which are adapted to permit of a circulation of cold air by means of which said walls are maintained in a relatively cool condition, preventing the rapid destruction or deterioration of said walls which would otherwise result due to the excessive heat to which they are subjected.

What is claimed is In a gas producer for furnaces, a pair of side walls, a division wall between said walls and constituting with the latter fire-boxes, an arched crown extending over and supported centrally by said division wall and having its ends extending over the respective fire-boxes and supported by the respec tive side walls, a rear wall common to each of the fire-boxes and having a horizontalpassage formed therein which passage extends across the rear end of the division wall and which has its ends communicating with the respective fire-boxes, and terminating at points central between the side and division having a top Wall supported by the top of Walls, said crown forming the top Wall the crown. 10 which defines the top. of said passage,and a In testimony whereofll afiix my signature passage extending from the horizontal pas.- in presence of two subscribing Witnesses.
