    A.D. 1854 .2280. Furnaces. LETTERS PATENT to William Grindley Craig, of Gorton, near Manchester, in the County of Lancaster, Engineer, for the Invention of “ Improve¬ ments IN THE Mode or Method op Consuming Smoke, and in the Machinery OR Apparatus employed therein.” Sealed the 20th April 1855, and dated the 26th October 1854. PROVISIONAL SPECIFICATION left by the said William Grindley Cr^ig at the Office of the Commissioners of Patents, with his Petition, on the 26th October 1854. I, William Grindley Craig, of Gorton, near Manchester, in the County 5 of I.ancaster, Engineer, do hereby declare the nature of the said Invention for “ Improvements in the Mode or Method of Consuming Smoke, and in the Machinery or Apparatus employed therein,” to be as follows :— I propose to arrange the fire-places of furnaces and boilers, whether for locomotive or stationary purposes, in such a manner that the smoke shall 10 always pass over or through a part of the fire, which is very hot, which I can accomplish by either making two fire-places, so connected, that whilst one is in a green or smoky state, the other will be red hot, over or through which the smoke will pass, and be thus consumed; or if I have only one fire-place I arrange tubes or flues in it, so as to cause a separation, and convey the smoke 15 over a red part of the fire.
