    Furnaces. (This Invention received Provisional Protection only,) PROVISIONAL SPECIFICATION left by Edward Ettrick at the Office of the Commissioners of Patents, with his Petition, on the 26 th February 1861. I, Edward Ettrick, of North Hylton, near Sunderland, in the County of 5 Durham, do hereby declare the nature of the said Invention for “ Improve¬ ments in the Construction op Furnaces for the Prevention or Consumption of Smoke,” to be as follows:— This Invention consists principally in the use or employment of longitudinal perforated tubes of metal, fire-clay, brick, or other material running parallel 10 with the sides of the furnace in the flame bed, in connection with a hollow per¬ forated bridge running across the same. Air from the ash-pit passes along two or more hollow tubes placed about level with the fire bars (or acting as fire bars) into the hollow perforated bridge, becoming intensely heated on its passage, and thence passing into the longitudinal perforated tubes is distri- 15 buted through the holes therein and in the hollow bridge into the furnace on all sides in small streams or jets, and mixing with the flame and combustible gases in the furnace effects the consumption or prevention of the smoke therein.
