    Alexander s Tmpts. in Furnaces and Apparatus for Manufacturing Sugar, <§c* trators, or assigns, should at any time agree with, and no others, from time to time and all times thereafter during the term therein expressed, should and lawfully might make, use, exercise, and vend, within the United Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of 5 Man, an Invention for “ Improvements in Furnaces and Apparatus for the Manufacture of Sugar, and for the Consumption or Prevention of Smoke,” upon the condition (amongst others) that I, the said William Richmond Alexander, by an instrument in writing under my hand and seal, should particularly describe and ascertain the nature of the said Invention, and in what manner the 10 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. ROW KNOW YE, that I, the said William Richmond Alexander, do hereby declare the nature of my said Invention, and in what manner the 15 same is to be performed, to be particularly described and ascertained in and by the following statement, reference being had to the accompanying Drawings, and to the letters and figures marked thereon, that is to say:— My said Invention relates to the arrangement and construction of furnaces and apparatus specially applicable to the manufacture of sugar, and also 20 suitable, to a greater or less extent, for consuming or preventing smoke in furnaces generally. As adapted for the purposes of the sugar manufacture, the arrangement consists of a long “ fire mouth ” or drying chamber, fitted up immediately in front of the furnace, such fire mouth or drying chamber being formed with a double bottom, perforated on the upper side for the discharge 25 into the chamber of heated air. The “ megass ” or waste sugar cane is deposited in this chamber, and pushed into the furnace from time to time for use through a perforated door, which forms the communication between the drying chamber and the furnace. The furnace bars are tubular, opening at one end into a hollow fire-bridge at the back end of the furnace, and at the 30 other into the false bottom space of the front drying chamber. The grate bars are also minutely perforated on their upper side, for the discharge of air amongst the burning fuel upon the bars. Air is forced into the furnace by a blowing fan or other mechanical forcer at the extreme back end of the structure of the furnace. The pipe from the fan conducts the air into and 35 through a set of heating cylinders or chambers studded with lateral spikes or projecting pieces of metal inside and out, to enable the air to take up a superior amount of heat. After leaving* this heater, the air is forced along a conducting pipe laid along the bottom of the main flue, and beneath the steam boiler, usually fitted up at the after end ot these structures, and beneath the
