    Hall's Improvements in Boilers, Furnaces, Flues, Chancery within six calendar months next and immediately after the date of the said in part recited Letters Patent, as in and by the same, reference being thereunto had, will more fully and at large appear. NOW KNOW YE, that in compliance with the said proviso, I, the said Samuel Hall, do hereby declare that the nature of the said Invention, and the 5 manner in which the same is to be performed, are fully described and ascer¬ tained in and by the following statement thereof, reference being had to the Drawings hereunto annexed, and to the figures and letters marked thereon, the same letters referring to the same parts in each figure on each Sheet respectively (that is to say): 10 I shall now state the objects and nature of my several improvements in the order in which they are mentioned in the said Letters Patent. Firstly, the object and nature of my “ Improvements in Apparatus for Effecting the Combustion of Fuel and Consuming Smoke,” are the making of furnaces more perfect for effecting those processes, the rendering of them as 15 well as the boilers to which they may be applied more durable, the economizing of fuel, and the reducing of the manual labor required in working them, being improvements upon that part of my Patent of the Twentieth day of February, One thousand eight hundred and forty-five, relating to “Improvements in Boilers, Furnaces, and Flues in Consuming Fuel and Preventing Smoke.” 20 Secondly, the objects and nature of my “ Improvements for Preventing Explosions of Steam Boilers, and other Accidents to which they are liable,” are the preventing of the water from becoming too low in such boilers, owing to the uncertain action of force pumps or other modes of supplying them with water, the preventing of the water from becoming too low in such boilers, 25 whether by leakages or other causes, while the force pumps or other apparatus for supplying them with water are at rest, as at meal times, &c., and the causing of the safety valves to act with unerring certainty by preventing their ‘ « 4 becoming staked or fastened down on their seats by accidental causes, or from being overloaded by being left to the discretion of firemen or other persons. 30 Having stated the objects and nature of my improvements, I will now describe the apparatuses in the same order as that in which they are herein-before enumerated, beginning therefore first with my “ Improvements in Apparatus for Effecting the Combustion of Fuel and Consuming Smoke.” Figures 1, 2, and 3, Sheet I, shew two boilers, to which my said improve- 35 ments are applied. A and A* are those boilers; B and Bx, the furnaces; C and Cx, the ash pits; and D and Dx, the hoppers for receiving the supply of fuel; E and Ex, F and Fx, and G and Gx, are three plates which form the backs of the hoppers, between which there are two spaces for supplying thin
