    Specification. A.D. 1866.—N° 3371. Claries Apparatus for Producing Draught and Purifying Smoke in Furnaces. maintaining and increasing the combustion, in fact, the exhausting action causes the smoke to pass to and fro above the fire, creating long flames whereby a portion of the smoke is consumed. This Invention is illustrated in the accompanying Drawings, Figure 1 of 5 which shows a central vertical section of the apparatus on the line 1, 2 ; Figure 2, which is a horizontal section of the same on the line 3, 4, Figure 1 ; Figure 3 is a vertical section of the apparatus on the line 5, 6, Figure 2; Figure 4 is a central vertical section of the purifying apparatus taken through the line 7, 8, Figure 5, which last is a horizontal view of the same. The 10 same letters of reference serve for all the Figures. a, reservoir of a size in proportion to the amount of smoke to be treated ; h, c, two cylinders fixed in a vertical position on the cover of the reservoir a, having between them an annular space which is filled with water to make hydraulic joints for the two movable bells or inverted vessels d of the cylinders, 15 which are received in the annular spaces and serve for extracting and dis¬ charging the smoke ; e, hinged joints with which are connected the mechanical parts serving to produce the rising and falling motion of the bell covers d, such as by a beam for example, while one cylinder is taking in the other is discharging, and vice versa, so that the smoke is being continually drawn from the 20 furnace ; /, manhole or opening for giving access to the suction valves ; g, point of communication between the reservoir a and the smoke flues; h, point at which the smoke passes to the purifier ; i, i, pipes for conveying water to the annular spaces in which the bells d, d, work ; j,j, discharge pipes for the water contained in the annular spaces ; k, k, openings for regulating the dis- 25 charge valves; l, suction valve ; m, discharge valve. By means of these valves Z, m, communication is effected between reservoir a and cylinders d, d; n, opening for removing any scoria or cinders which may be contained in the water introduced into the discharge chamber through the openings k, k; o, o, division plate separating the reservoir a into two parts or chambers ; the 30 one termed the suction chamber is provided with a suction or inlet valve Z, the other and discharge chamber having a discharge valve m; p, grating of the purifying apparatus for supporting the coke or other matters for separating the constituent parts of the smoke or absorbing a portion thereof; q} bottom of the purifier below the grating p ; r, opening for removing the scoria from 35 the bottom of the purifier; s, pipe for the passage of the smoke into the purifier; Z, overflow pipe for the water through which the smoke passes; u, opening affording access for cleaning the grating p, p ; v, matters for purifying the smoke by separation to facilitate its washing with water, and if necessary ♦ J absorbing it in part; wy tube or plate provided with small perforations for
