    LewaVs Improved Method of and Apparatus for Consuming Smoke, $c. is fixed a vertical pipe or tube of any length and form adapted to the size of the apparatus, these pipes or tubes communicate with and are attached to an air chamber fixed above, from which chamber one or more pipes convey the heated air into other pipes, flues, or chambers, placed in any position required. Or the two boxes may be removed, the pipes or tubes placed horizontally in the 5 cold air chamber, and the flame pass through the said pipes or tubes. In the space between the pipes or tubes is placed another chamber to contain the coal or any other fuel that may be used. This chamber has no communication with the chimney or flue except through the fire, but at the top a pipe or tube is attached to convey the excess of smoke or gas that cannot pass through the 10 fire to an opening immediately beneath a number of fire-bars fixed at the bottom of the said chamber ; these bars are placed longitudinally and parallel to each other, or in the form of an arch, or in any other position most suitable. Affixed to the front of the coal chamber of the apparatus is a frame pierced with three or more openings of any suitable form, to which are fixed doors or 15 slides for supplying the fuel and regulating the supply of air for proper com- bustion. The apparatus is placed in a brick chamber built in a suitable form, and in any convenient position. The principal improvements in this Invention are, 1st, that the smoke and gas generated by the combustion of the fuel are entirely consumed, thus 20 increasing the heating powers of the apparatus without causing any additional consumption of fuel. 2nd, that no smoke being admitted into the chimney or flue, it is only required to cause the necessary draught of air to pass through the fire to promote combustion; it may therefore be placed in any position in the building 25 without the fear of discolouring or injuring the material, or causing any annoyance or inconvenience. 3rd, that by the constant passing through the apparatus of large quantities of pure warm atmospheric air into the building a more healthy and better atmosphere is obtained. 30 4th, that the heat produced is divided and caused to pass round or through the pipes or tubes, thus increasing the heating surface and utilising the whole of the heat generated by the fire. Thus it will be seen that the Inventor by this principle obtains the entire consumption of the smoke; the more perfect combustion of the fuel ; the 35 utilising of the whole of the heat generated ; and the introduction into the building of pure warm air that has not been brought in contact with the fire or red-hot surfaces of iron. That portion of the apparatus for consuming the smoke is also applicable to
