    r~a~-i i~fc —i«—> i———»iV>^ A.D. 1855 .N° 605. Furnaces, &c. (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 Benjamin Cook at the Office of the Commissioners of Patents, with his Petition, on the 19 th March | 1855. I, Benjamin Cook, of Chester Street, Kennington, in the County of Surrey, 5 Furnace Builder, do hereby declare the nature of the said Invention for “ Improvements in Machinery or Apparatus for Consuming Smoke ” to be as follows:— Instead of the various modes of consuming or preventing the escape of smoke from chimneys, &c. hitherto employed, I propose to affix to the front 10 or opening of the furnace a framing having two or even more doors. One of these doors, the lowermost, will be the usual door opening for the purpose of feeding the furnace; and the other, or uppermost door, will be for the admission or production of highly rarifieu and subdivided air. I also propose placing at the feeding portion of the furnace opening, and (as it were) under 15 the floor thereof, a dead plate (which plate will be cast or made hollow); from this plate, or the floor of the feeding part of the furnace, the furnace bars will rise in an incline upwards to the middle of the furnace bridge; the furnace bars may be made hollow or solid. I expect to obtain air at the con¬ nection of the bars and the bridge, which air will proceed from the hollow 20 of the dead plate through the ash-pit between or through the furnace bars.
