    2 Provisional Specification, Claries Improvements in Smoke-consuming Apparatus. transformation by disengaging and eliminating tbe incombustible gases, the combustible gases being returned in a continuous manner under the fire where they are burnt and aid in the production of heat. These improvements are illustrated in the accompanying Drawing, which shows a sectional elevation of a smoke-consuming apparatus applied to a steam generator. 5 a represents the brickwork of the boiler furnace; I, chimney; c, furnace bars. The two latter parts, namely, the furnace and flue, are of the ordinary con¬ struction and do not require any modification to admit of the application of the smoke-consuming apparatus, which may be adapted thereto or removed at pleasure; d, sheet or other iron damper adapted to the chimney and cutting 10 off the passage of the smoke into the atmosphere; this damper is always closed, as except in cases of repairs or cleaning the boiler, this boiler furnishes sufficient steam during the night, so that the stoker has only to place the apparatus to work at the time the fire is lighted ; /, chamber or recipient placed in communication with the chimney h by means of pipe g serving to 15 conduct the smoke; this chamber is filled with water, and the smoke on passing into it becomes deprived of its impurities, such as ashes and particles of coal that may escape from the combustion, which matters being heavier fall to the bottom of the receptacle, the smoke is also deprived of a portion of the steam it contains; this chamber may be supplied in a continuous manner, and 20 furnished with an overflow pipe for getting rid of the surplus water; a water guage may also be applied for indicating the rate and progress of the supply, ft, draw-off cock for the liquid in the reservoir; i, apparatus for purifying the smoke ; j, pipe connecting the apparatus i with reservoir /. This purifying apparatus is composed of a chamber divided at the upper part into compart- 25 ments consisting of perforated sheet iron k; on each of these is disposed lime in powder, mixed with hay, moss, or other simila^f spongy matters, through which the smoke is caused to pass and thereby become filtered and purified of the gases and carbonic acid and steam it contains; the carbonic acid com¬ bining with the lime transforms the latter into carbonate of lime; the smoke 30 which is then composed of combustible gases is finally washed in the milk of lime contained in the lower part of the apparatus, and passes out in a pure state through pipe I to an exhauster, into which it is drawn; m, emptying cock of the purifying apparatus ; w, exhauster serving to draw the smoke through pipe I, and fixed on one side of the apparatus. One side of this apparatus is 35 open to admit of the introducton of a certain quantity of air which becomes mixed with the smoke, the whole is then forced through pipe o into the ■ furnace under the fire-bars. The lower end of pipe o is expanded in the form of a fan in order that the smoke may be spread and distributed over all parts
