    Milner's Impts. in Combustion of Smoke in Steam Boiler Furnaces. our Lord One thousand eight hundred and seventy-two, in the thirty- sixth year of Her reign, did, for Herself, Her heirs and successors, give and grant unto me, the said Ezra Milner, Her special license that I, the said Ezra Milner, my executors, administrators, and assigns, 5 or such others as I, the said Ezra Milner, my executors, adminis¬ trators, and assigns, should at any time agree with, and no others, from time to time and at ail times thereafter during the term therein expressed, should and lawfully might make, use, exercise, and raid, within the United Kingdom of Great Britain and Ireland, the Channel 10 Islands, and Isle of Man, an Invention for “ Improvements in Means for Facilitating the Combustion of Smoke Produced in the Furnaces of Steam Boilers,” upon the condition (amongst others) that I, the said Ezra Milner, my executors or administrators, by an instrument in writing under my, or their, or one of their hands and seals, should particularly 15 describe and ascertain the nature of the said Invention, and in what manner the same was to be performed, and cause the same to be filed in the Great Seal Patent Office within six calendar months next and immediately after the date of the said Letters Patent. NOW KNOW YE, that I, the said Ezra Milner, do hereby declare 20 the nature of the said Invention, and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement thereof, that is to say :— The object of my Invention is by facilitating the combustion of smoke produced in the furnaces of steam boilers to increase the heating power 25 obtained from the fuel consumed. Eor this purpose I form a retort or enclosed chamber or small furnace in the passage or a part of the flue space formed in the boiler for the smoke and products of combustion from the main fire-place, and I generally form this chamber of fire-brick or fire-clay, the object being to employ for the purpose material adapted 30 to receive and impart a high degree of heat. This heat by acting upon the smoke and products of combustion in the flue passage will not only facilitate the combustion of that smoke, but will also increase the heat in such passages in the further progress of the products of com¬ bustion therein until they reach the outlet to the chimney and economise 35 fuel. The boiler is formed as for two internal fire-boxes and flues, and I use one of them as such in the ordinary way, but the other fire-box with its flue is divided and the small retort or such like chamber is fitted
