    Swift, Extra. 4 Qoa£s Jmpts. in Apparatus for Consuming Smoke and Economizing Fuel. The same letters of reference being marked on the corresponding parts in this and the following Figures, as also in Figure 1, no further description will be necessary. Figure 3 shews another mode of effecting the same object by a series of short tubes G, G, placed horizontally across an enlargement of the chimney at its lower part, one end of each of the said tubes communicating 5 with the chamber K, which said chamber is open to the atmosphere by the short pipe L; the other ends of the said short pipes terminate in the chamber M, from which the pipe II descends and passes to the bridge. In the said Figure 3, I have represented the manner of employing a wind fan, which is shewn Q,t N. In adapting my said Invention to the furnaces of steam boilers 1( of marine or locomotive engines, I prefer using a hot air chamber at the lower end of the chimney, as shewn in a sectional elevation at Figure 4, and in a horizontal section at Figure 5, with tubular flues passing through the hot air chamber. F, F, is the chimney or funnel; D, D, a cylindrical chamber introduced into the chimney, resting on brackets ; P, P, represent a number of 14 vertical pipes or tubular flues carried through the cylindrical chamber for the passage of the hot vapours and gases from the furnace to the chimney; Q, Q, are short pipes for the admission of atmospheric air into the chamber D, which air, after having become heated by its passage between the pipes P, P, P, within the chamber, proceeds through the larger tube R, which is connected by 2( a cone and socket to the pipe H, and is discharged at the bridge of the furnace for the purpose of inflaming the smoke, as herein-before mentioned. In witness whereof, I, the said Richard Coad, have hereunto set my hand and seal, this Twenty-third day of December, in the year of our Lord One thousand eight hundred and thirty-five. 2i RICHARD (l.s.) COAD.
