    2 A.D. 1856.—N° 1912. Provisional Specification. Dubs $ Evans Improvements in Effecting the Consumption of Smoke. unconsumed gases which are evolved therefrom are made to pass through the incandescent fuel at the lower end of the grate, and through openings in the mid-feather, which being highly heated will greatly assist in the combustion of the smoke; as the combustion of the fuel proceeds, the grate is gradually lowered, and the incandescent fuel pushed forward, or allowed to descend to 5 the lower portion of the grate to leave room for the fresh fuel to be introduced.
