HUNT President-elect American Institute of Mining Engineers Blast-Furnace Charging Apparatus.* — A device for charg-ing blast furnaces has been so designed that the contents of thehopper may be directed toward the sides of the furnace or maybe divided into two streams, one flowing toward the middle ofthe furnace and the other toward the sides. The inventor isGibbon C. Shackleford, Allegheny, Pa. Fig. 1 is a sectionalelevation of the upper portion of a blast furnace, showing thearrangement of the charging apparatus. In Fig. 2 the bell isshown as lowered. There is the usual hopper a, with its lowersides b converging and having a central discharge opening. Theopening is closed by the bell c, which is of the usual shape andconstruction and fits closely into the opening in the distributing bell d has its upper end cut away so as to forman opening into which the main bell will fit, closing the openingin the distributing bell.
