    Consuming Smoke and Obtaining Motive Power therefrom. .. ■ ■ - - . -—- (This Invention received Provisional Protection, but notice to proceed with the application for Letters Patent was not given within the time prescribed by the Act.) PROVISIONAL SPECIFICATION left by John Arrowsmith at the Office of the Commissioners of Patents, with his Petition, on the 6th July 1854. I, John Arrowsmith, of Bilston, in the County of Stafford, Engineer, do hereby declare the nature of the said Invention for “ A New or Improved 5 Method of Consuming or Suppressing Smoke, and Obtaining Motive Power therefrom,” to be as follows:— I draw the heated air and smoke from steam boiler and other furnaces and fires, by means of an exhausting pump or fan, or by the draft of a large chimney, or in any other convenient way, and cause the same to pass through 10 and over one or more coke fires, whereby the said smoke becomes so heated that it combines with the oxygen of the air with which it is mixed, and the heat thus obtained may be used to heat a steam boiler, or for other purposes. If there is not sufficient air mixed with the smoke I mix more air therewith ; or the smoke and air mixed with it may be passed through a heated tube or 15 chamber, and made to combine or directed upon a lighted jet of coal gas for that purpose. In large manufactories and buildings I make a large central tower or chimney, into which I make the flues from the various furnaces and fires open, the ascending current of heated air in the said tower or chimney
