    JBlampoiVs Improved Smoke-consuming Apparatus. Figure 1 shewing the application of my improved smoke-consuming appa¬ ratus to a locomotive engine, and Figure 2 its application to a stationary engine. At Figure 1, A indicates an upper boiler tube which breaks the direct 6 horizontal draught; B, a lower boiler tube serving to intercept and divert the vertical draught; C1, current of flame reserved to return to direct horizontal draught for the passage of the smoke to the upper part of the fire-place; C, tubular passages and current of flame; D, bottom vertical moveable grating serving to increase the combustion as air hole, and for throwing off 10 scoria; E, fixed inclined grating serving to receive the fuel, it is inclined at an angle of 35°/0; F, moveable door of fire-place ; X, supports of the grating or fire-bars; M, moveable damper to close the air inlet of the vertical grating ; L, ash-pit and fire-guard; K, boiler and steam reservoir; Y, upper part of furnace. 15 The result obtained by this apparatus is the physical combination of the vertical and horizontal draughts, with the object of rendering the smoke incandescent with the flame. The vertical draught in connection with the vertical grating and the lower part of the inclined grating by the current of flame C, which separates the boiler 20 tubes B, A, draws the flame of the fuel which covers this space, and finds itself in combustion and consequently purified, the result is, that when the smoke of the fuel which covers the upper part of the grating is slanted and attracted by the vertical draught to the current of flame C, it is entirely destroyed by the flame of the fuel which covers the lower part of the inclined grating and 25 of the vertical one. The direct horizontal draught being virtually suppressed by the tube A, the little smoke which it draws through the space reserved at its upper part for the current of the smoke C1, gives for result a continuous eddy in the upper part Y of the furnace, and again comes to destruction in the flame of the vertical draught. 30 The application of this apparatus presents the following advantages :— Firstly, the manual labor of withdrawing the coal cinders is rendered very easy by the grating D, which is worked from the platform. Secondly, of giving to the boiler by the effect of the vertical draught the generation of the production of the steam in the parts sensible to heat by 35 means of direct flame at the tubing. Thirdly, easy inspection of and stopping of tubes, and lowering of steam pipes avoided in the replacing of the tubing, as the space between the boiler tubes B, A, leaves room for the passage of a workman in placing the tubes.
