FIG. 5.—PLAN OF CONTINUOUS REGENERATOR of cast iron tubes suitably carried on cast iron plates, allowancebeing made for their free expansion. The gases from the boilerpass down the tubes to the chimney flue. The air to be heatedwill be drawn from the tipping floor overhead, circulated aroundthe tubes, and be led away to the hot air conduit, which runsunder the ashpit floor of furnace, suitable openings being left forthe air to pass to the air boxes, carrying blowers. The engravingsshow an overhead platform and portion of another unit. As theplatform will be of an ordinary construction, it is unnecessary todescribe it. The method of firing will be by hand, the refuse beingtipped from the cart into the containing hopper (Figs. 2 and 3).which will have a capacity equal to a days supply. In charging destructors many favor the hopper method of feed-ing on to a drying hearth, but if it is carefully considered it willbe seen that hand firing is to be preferre
