    Bayliss Impts. in Consuming or Preventing Smoke df Pleating Liquids. the fuel getting amongst the admixers, and is retained in its proper position by means of projections on the under side, one at each end, which fit into holes in the top of plate E, on which it rests. K, shewn in dotted lines, is a deflector for throwing the flames downwards, and 5 giving it an extended sweep under the rest of the boiler; but this may be dispensed with, not being essential to the action of the apparatus. It will be seen by the foregoing description that the gases cannot fail to be brought into the most intimate mechanical mixture with the air, in the endeavour to find their way through the numerous channels 10 presented to them by such an array of bars, and the agitation conse¬ quent thereon; and as the bars become red hot, and form besides a great natural harbour for heat, a steady combustion goes on from one end of the admixers to the other. A row of admixers is represented separately at Figure 5, which is a front elevation; Figure 6, a vertical 15 section; and Figure 7, a plan. Figures 8, 9,and 10, shew respectively a front elevation, vertical section, and plan of another mode of con¬ structing the rows of admixers, the difference being that the base b, is made with holes through it, in which the upright bars c, are fixed. Figure 11, is a vertical section of a third plan, varying from the latter SO only in having projecting shoulders g, on the bars c, in lieu of reducing the thickness of them at their lower ends. Perforated plates of metal or slabs of fire-clay might be used in substitution of the admixers already described. The admixers may be placed vertically or horizon¬ tally, as is thought best. I prefer having the admixers made of cast 25 iron, when the heat of the furnace is not so intense as to burn them away too rapidly, on account of the cheapness of the metal, and the facility it offers for renewing them. For furnaces of very high tempe¬ rature, the plan shown in vertical section at Figure 14, may be adopted with advantage. It is composed of two vessels of plate iron L, M, 30 built in the sides of the furnace, and connected together by metal pipes or tubes h, which serve as admixers, &c. A pipe N, communicates with the force pump, and another pipe P, with the boiler; and thus all the water that enters the latter must pass through the tubular admixers, and, by absorbing the heat, prevent them from being burnt
