    2 Schafhoeutl, $ E.O. § J. Manby s Improvements in Reverberatory Furnaces, Manby shall cause a particular description of the nature of their said Inven¬ tion, and in what manner the same is to be performed, by an instrument in writing under their hands and seals, or under the hand and seal of one of them, to be enrolled in Her said Majesty’s High Court of Chancery within six calendar months next immediately after the date of the said in part 5 recited Letters Patent, reference being thereunto had, may more fully and at large appear. NOW KNOW YE, that in compliance with the said proviso, I, the said John Manby, do hereby declare the nature of my Invention, and the manner in which the same is to be performed, are particularly described and ascer- 10 tained in and by the following description thereof, reference being had to the Drawing hereunto annexed, and to the figures and letters marked thereon (that is to say):— Reverberatory furnaces, as at present constructed, consist of a single fire¬ place at the extremity opposite the chimney, by which disposition the flames 15 are made to pass from the fire over the substances to be acted upon to the chimney in one direction only, and our improvements consist in surrounding the substances to be acted on by the fire and flames (except at such places as are necessary for the introduction of the substances themselves and the tools • for working them, and for the eduction of the flames or products of com- 20 bustion from the furnace to the stack or chimney,) in such manner as that the flames and products of combustion are made to act on the substances in the furnace from all sides, instead of from one point only, by which means anthracite or stone coal and culm, and other short-flamed fuels that heretofore have been considered inapplicable to the process, may be used, as well as 25 bituminous coal and other long-flamed fuels. In order that the Invention may be more fully understood, 1 shall describe it with reference to the Drawing, which contains plans and sections of a furnace constructed on the principles of our Invention. Figure No. 1 represents a longitudinal section through the centre of the furnace; No. 2 is 30 a transverse section, also through the centre of the furnace; and No. 3, a sectional plan above the puddling hearth or bottom. It will be seen, by reference to these three sections, that instead of the usual single fire-place or grate, as in the reverberatory furnace as at present constructed, our fire-place or grate surrounds the working hearth or bottom, on which the metals, ores, or 35 other substances to be acted on are placed, except only where interrupted by the working door and the canal leading to the chimney, the one being placed opposite to the other. By this disposition the ores or metals introduced into the furnace are acted on by the heat and flames from all sides, instead of from
