    Fontenays Improvements in Smolce-consuming Furnaces. position, by preference, parallel or nearly so to the large grate J, K, L, and at such distance apart from the latter as to leave room for the fuel on the grate and for the gases evolved by the fuel to pass freely, in the manner as represented in the Figs. 1 & 4. The small boiler F may be in direct communication with 5 the main boiler B, or the same may be entirely separate therefrom and be replaced by an inclined iron screen, or even by a partition of fire-bricks, or other suitable material; by preference, however, the liquid in the small boiler F and that in the main boiler B should be in direct communication by the tubes or tubular wings G, and the small boiler duly fixed to the large one, and to 10 the sides of the furnace, by means of screw bolts P, rivets or other suitable contrivance, allowing of easily replacing this small boiler F by another one. One of the tubular wings G is situated at each side of the door M, and they leave between them an opening H, provided with a sliding plate, folding door, or other suitable means for allowing either to shut this opening H, or by 15 means of the same reach the under part of the main boiler B, evaporating pan, or other vessel to which the boiler F is attached, or even the fire tubes of the boiler of a locomotive engine, whilst for lighting the fire this sliding plate or folding door is opened, in order to allow the smoke arising at that moment easily to take its exit through the opening H. 20 In Fig. 3, one of the tubular wings G and the top plate U of the boiler F are represented as partly cut away. The lower end of the small boiler F should be provided with a screw plug /, for allowing to empty or clean the same. For stationary steam engine boilers, evaporating pans, or other similar fixed vessels, the opening H might entirely be dispensed with, and the small 25 boiler F connected over its entire width to the lower part of the main boiler B. In this case it will be good that the sides of the small boiler F should project for a small distance through the lower part of the large one, so as to prevent any sediment to collect in this small boiler. As has been mentioned above, the small boiler F might be replaced by an inclined iron screen or partition 30 plate, or by a wall of fire-bricks, or other suitable material, situated in a suit¬ ably sloping or even in the vertical position, in order to force the smoke emitted by the fresh fuel on the front part of the grate to pass through the flame of the highly incandescent fuel at the further end of this grate. From w hat has been described may be inferred that as the fuel on the 35 further end of the grate is constantly kept in a highly incandescent state, and as the smoke evolved by the fresh fuel on the front part of the grate is pro¬ jected at right angles or nearly so in the flame of the highly incandescent part of the fuel, this smoke in the presence of a suitable quantity of atmospheric air will be fully decomposed into gaseous products, so as no more to be
