Patented 1876. This boiler has all the essen-tial qualities of the later watertube boilers. Ample water circulation isprovided for by the back con-nections, one of which is shownin the cut. 90. DOWN DRAUGHT WOOD-BURNING FURNACE. Thecurved chute facilitates the self feedingof the wood to the grate. Width ofchute suitable for cord wood. Firetrimmed from a side door. St. Clairtype, which is also adapted to the burn-ing of bituminous coal. 91. GRAVITY FEED FUR-NACE. For an internal fire-boxboiler. For bituminous coal the in-clination of the grate made to suit thesliding properties of the coal. Thefeed hopper extends clear across thegrate width. The coal feeds down byrate of combustion, which in turn isregulated by the amount of draft ad-mitted. The new coal is heated bythe burning fuel before it properly catches, and thus a preliminary evo-lution of gas is effected, which lessensvery perceptibly the amount of visiblesmoke given off by the furnace. GENERATION OF POWER, STEAM. 59. 92. TRAVELING LINKGRATE. The link-bar grateis fed forward by a geared drumcarrying the coal fed from ahopper and coked under thefore arch of the furnace. Mo-tion of grate and amount of coalregulated by speed of gear andopening of the hopper, slidingdoor, and grate guard. 93. UNDER FEEDFURNACE. A circulargrate with a central recess towhich the coal is lifted fromthe magazine by a spiral car-rier. The coal is pushed upthrough the central funneland falls over on to the grate,which is circular. A, magazine or hopper. B, feed screw. 94. DOWN DRAUGHT FURNACE in an internal fired type.
