    Loslis Impts. in Fire-places or Furnaces for FTeating Ovens, only, required five hours, kept the whole time full of wood and round coals. As the fuel required to heat any vessel on my principle is less than half of what is employed to produce the same effect in vessels placed on the usual plans, and as a much greater proportion of the smoke arising from a given quantity of fuel 5 is consumed by furnaces constructed on my plan, the quantity of that substance thrown into the atmosphere is exceedingly diminished, and by the introduction of a small cinder fire in the flues leading to the chimney, the black matter of the smoke, which is very inflammable, might be nearly wholly consumed. In the annexed schedule I have delineated eighteen Drawings of the fire-places or 10 furnaces for heating ovens and boilers. Figure 1 represents a vertical section of an engine boiler and furnace where the cold air is entirely prevented from mixing with the heated gases until after they have ceased to act in the boiler. Figure 2 represents an horizontal section of the same taken at the line B, B. Figure 3 represents another horizontal section of the same taken 15 at the line A, A. a, a wall which extends from the bottom of the ash-hole to the bottom of the boiler and to the top of the flues or space for con¬ taining the heated air round the sides of the boiler. This wall cuts off all communication between the two furnaces and grate rooms or spaces for con¬ taining the heated gases, and gives support to the bottom and sides of the 20 boiler, b shews the grates or bars on which the fuel is burnt; c, a plate of metal or other fit substance which seperates the ash-hole and grate room, and prevents the ascent of the atmospheric air from the former to the latter; d, the door frame; e, the door; f,f pillars on which the boiler rests, with a bearance of nine inches (more or less according to the size of the boiler) within the 25 extreem periphery of the bottom; y, caps or covers of cast metal for the pillars; h, the boiler; i, i, the spaces round the sides of the boiler into which the heated air ascends from the grate room through the opening l between the pillars f,f\ j, a wall surrounding the spaces i, i; k, spaces through which the heated gases after acting on the boiler take their exit from the grate room 30 to the chimneys, which may rise immediately above each fire door, or the heated gases and smoke may be conveyed through flues to one chimney placed in any convenient situation, as shewn on the plan, Figure 3. Figure 4 repre¬ sents a vertical section of a steam engine boiler, where the cold air of the atmosphere is prevented from mixing with the heated gases until after they 35 have ceased to act on the bottom of the boiler, a, b, c, d, e, are explained in Figures 1, 2, and 3 ; f a wall on which the boiler bottom has a bearance of nine inches, more or less ; i, i, i, i, flues, into which the heated air, smoke, &c., ascend from the grate room at g,g,g,g, in Figure 5 ; j, outside wall.
