    Taylor s Improvements in JBoilers and Apparatus connected therewith. nected to the top of the chimney, which pipe S descends to an exhausting and blowing apparatus, having a valve placed at the lower end opening into the cylinder of the blowing apparatus. V is a pipe leading from the exhausting and blowing apparatus W through the ash pit and into the recess, or well formed under the bars at the fire-place at X, which recess or well is shown as constructed 5 of fire bricks, and is open at top into the fire-place, whereby it is at all times filled with coals, and at the bottom it is sufficiently open to permit of the ashes being raked out, but which ashes are always to be kept sufficiently above the opening at the bottom of the well X to prevent the smoke which is forced through the pipe V being driven in any other direction than upwards through 10 the burning coal, as will be fully described hereafter. Having now described the parts represented in this Figure, I will proceed to describe the manner of their action. The fire being lighted, the smoke will pass along the flues P, P, and thence into the chimney Q, from whence it would pass out into the atmo¬ sphere through the outlet R, but that it is prevented by the working of the 15 exhaustion and blowing apparatus W, which will cause the smoke to pass through the pipe S into the cylinder W, whenever the piston in such cylinder is raised, and the return stroke of the piston will force the smoke so withdrawn from the chimney through the pipe V, into and through the burning coal, and thus will the smoke be continually forced through the fire; but in order to 20 have a continued action of the blowing apparatus in withdrawing and forcing the smoke it will either be necessary to have two cylinders working in succession, or to have a closed cylinder, the pipes S and V being connected with the top and bottom of such cylinder, as is well understood in making exhausting and blowing apparatus. It will be necessary here to observe that as the black and 25 dense smoke is only evolved at and a short time after the putting on of fresh coal, it will only be necessary to work the exhausting and blowing apparatus so long as such dense smoke is evolved; this apparatus must therefore be attached to the engine in such a manner as readily to be put into and out of geer, and when disconnected from the engine sufficient draft will be kept up by the 30 outlet R, but in case there be a feeding apparatus applied to the furnace, whereby a continuous supplying of coals is kept up, then the exhausting and blowing apparatus should be kept in continued action. Fig. 4 shews another plan of consuming the smoke in furnaces, and consists in passing a pipe or pipes through the heated coal in such a manner that the smoke evolved 35 must pass through such healed pipes, and thus will the smoke be consumed. Y, Y, Y, are three pipes open at their ends Z, Z, Z, being opened for the passage of the smoke and heated air, which not being able to find vent at any other part of the furnace are obliged to pass down through the pipes Y, Y, Y,
