    Clark's Apparatus for Producing Draught and Purifying Smoke in Furnaces. me from abroad by Claude Moret, Mechanical Engineer, and Felix Raux, Gentleman, both of 29, Boulevart St. Martin, Paris. NOW KNOW YE, that I, the said William Clark, do hereby declare that the following Complete Specification under my hand and seal fully describes and ascertains the nature of the said Invention, and in what manner 5 the same is to be performed in and by the following statement, reference being had to the Sheet of Drawings hereunto annexed, and to the letters and figures marked thereon (that is to say) :— Many attempts have been made to prevent the dispersion into the atmo¬ sphere of the black smoke produced by the combustion of fuel in furnaces, and 10 various combinations of apparatus have been tried and proposed without, however, answering the purpose entirely, and even if partially successful in some cases it has been at the expense of the fuel, at the same time increasing the liability to accident. This Invention relates to apparatus for attaining the desired result in a 15 perfect economical and available manner. This apparatus intercepts the smoke which would otherwise pass into the atmosphere in a highly heated state as near as possible to its point of production and transforms it into a white vapor, which condenses in the air without disengaging any black particles. The apparatus consists, 1st, of a reservoir formed of metal, masonry, or 20 otherwise, of an extent in proportion to the amount of smoke to be inter¬ cepted, and divided into two compartments for the inlet and outlet of the smoke. 2ndly. Of cylinders provided with water joints of a circular or other form, each provided with two valves, one for the suction and the other for the 25 discharge; these cylinders are worked alternately by means of a beam or other means of transmission driven by a steam engine or hand power. 3rdly. Of a metal or other receiver containing small coke or other separating matters supported on a grating, into which matters water is injected from above. The smoke after passing through about 8 inches of water under 30 the grating traverses the coke or other matters containing water as above mentioned, where it becomes separated from the unconsumed parts, and is discharged into the atmosphere from the receiver in the form of a white vapor, like steam, at a greater or less height, or it may be condensed by refrigeration, in order to extract any remaining products of combustion, or 35 used for any heating purpose. By reason of the exhausting action of the cylinders mounted on the reservoir which is in communication with the furnace flues, the products of combustion are withdrawn, and a vacuum being created, more or less partial, a quantity of air passes down through the grating for
