    Milburn Sf Jacksons Improvements in Decomposing Noxious Vapours. and propels them through the piping d into the ash-pit of the furnace C, whence they flow through the fire in the said furnace and through the flue 0 into the ash-pit of the main furnace B. The said vapours or the residue thereof then flow through the main furnace, and the residual gases or vapours and gases are conveyed away through the flues 5 employed as means for heating the drying floor. If found or considered to be desirable in any case air may be caused to mingle with the vapours before passing through either the first or the second fire. In some cases it may be desirable to pass the vapours into a condensing chamber or through chambers before the said vapours are 10 admitted to the fire, and in some cases it may be of advantage to put water, or acid, or other liquid or substance in such chamber or 4 > chambers. The dotted lines p indicate such a chamber. Although we have only shewn two furnaces acting in conjunction, in the example selected for illustration, we do not confine ourselves to 15 this number. We may use a set of four furnaces arranged in two pairs, and provided with doors or dampers, so arranged as that the current of vapours can be divided and be conveyed into the ash-pits of the two first fires, and also that when required the whole of the vapours can be conveyed into either one of the said two ash-pits. ' 20 When it would be necessary to open the fire or ash-pit doors of a furnace in one of the pairs of furnaces the dampers would be arranged to direct the whole of the vapours through the other pair of furnaces. We have found it to be of importance to convey the vapours through more than one fire as one fire only has not sufficient effect. 25 Having now fully set forth and indicated the nature of our said Invention, and the manner in which we carry and may carry the same into practical effect, we would have it to be understood in conclusion that we claim,— > . First. Forcing or conveying vapours, or vapours and gases, resulting 30 as herein aforesaid successively through two or more fires. Secondly. The method of, and arrangements for, decomposing or rendering less noxious vapours resulting from the treatment of matters herein indicated, substantantially as herein-before set forth and in¬ dicated.
