    Frankham s Impts. in Consuming Smoke and Economizing Fuel in Furnaces. bridge, to allow flame from the incandescent fuel to pass to the back of the bridge and up behind it, where the flame will meet with the combustible gases that are passing away over the bridge f from the fuel unconsumed. Just at this point atmospheric air to effect the combustion of the gases is admitted from the ash pit through the passage h (Fig. 1), the supply of air being regulated by a 5 valve i (Fig. 1), which is opened or closed by means of the long rody. In one or both o,f the side walls of the fire-place, and parallel therewith, is made a horizontal lateral flue k, k, which communicates with the fire-place by side openings l, Z, Z, through which the smoke and unconsumed combustible gases are drawn off into the lateral flue k by the draught from the chimney. One 10 end of this flue k is provided with a door m, that access may be obtained thereto for the purpose of clearing out the flue when required. The other end of the flue k communicates with the main flue just behind the bridge/, as shewn in the plan view, Fig. 3, and the gases conveyed by the flue k are therefore brought into contact with the flame from the fire, which, when supplied with 15 oxygen from the atmospheric air that enters by the channel or passage h, effectually consumes the smoke and combustible gases, and thereby generates great heat under the boiler. Having now described my Improved Means of Consuming Smoke and Economizing Fuel in Furnaces, and explained the manner of carrying the 20 same into effect, I claim as of my Invention the means herein shewn and described, or any mere modification thereof, for consuming the smoke and com¬ bustible gases evolved from the fuel of fire-places or furnaces, whereby such smoke or gases will be drawn off from the fuel, and brought into contact with and intimately blended or mixed with the flame from the incandescent flue in 35 the presence of oxygen, obtained from the atmospheric air admitted to the flue to promote combustion, as above described. In witness whereof, I, the said Samuel Frankham, have hereunto set my hand and^seal, this Twelfth day of February, in the year of our Lord One thousand eight hundred and fifty-five. 30 SAMUEL FRANKHAM.
