    Smoke-consuming Apparatus. (This Invention received Provisional Protection only.) PROVISIONAL SPECIFICATION left by Richard North at the Office of the Commissioners of Patents, with his Petition, on the 23rd April 1864. I, Richard North, of Birstal, near Leeds, in the County of York, do 5 hereby declare the nature of the said Invention for “ Improvements in Smoke¬ consuming Apparatus,” to be as follows :— My Invention has for its object the more perfect combustion of fuel in the fires of steam and other boilers, and the consequent economy obtained thereby. I effect this by placing at the mouth of the furnace or flue, upon the “ dead 10 plate,” a tube by preference square in section, and provided with small apertures on that side which is presented to the fire ; this tube may be curved on its outer edge to the radius of the flue (when applied to boilers * fired internally) and form in fact, in conjunction with the dead plate and the door, the front part of the furnace fittings. Holes cut in the dead plate 15 corresponding in size and position with that of the tube admit the outer air, the supply being regulated by a valve being placed at each end of the tube, the said valves being connected by suitable mechanism, and opened or closed at the will of the attendant. By means of the above-named apparatus jets of air are thrown in at the front part of and equally all round the furnace 20 through the small apertures before named, a principle which experience proves to be superior to those in common use, inasmuch as the combustion of the fuel is more perfect.
