MARINE WATERTUBE BOILER. A lightand powerful boiler inventedby Du Temple in France andused on an English torpedogunboat. 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,
