Chemical engineering . certain ore withproper fluxes and proper attendance, it is possible to predictalmost exactly the result that will be obtained in a smeltingfurnace of modern construction. The modern smelting fur-nace is the result of a process of evolution. It has been de-veloped by the cooperation of the metallurgists at the smeltingplant with the manufacturers of smelting furnaces. The following notes describe the latest types of blast fur-naces, both for lead and for copper smelting, made by theAllis-Chalmers as the result of some forty years experi-tnce as manufacturers of machinery for the mining and reduc-tion of ores. Small furnaces arc made round and will not beconsidered in the following. Large furnaces are built rec-tangular in shape. All the dimensions given in the followingare measurements made inside the jackets of the tuyere \st Fukn.^ce for Le.\d Smelting. The general design of the modern 44-inch x 144-inch steelwater-jacketed lead furnace, made by the .\llis-Chalmers Co.,. FIGS. I .\ND 2.—RECT.\NGUL.\R STEEL \V.\TEK-J.\CKETED LEAD I-LRN ACE, 44 X 144. is shown in Figs. I and 2, which give a half section and endelevation. The curbs of these furnaces are of steel or cast-iron plates, resting upon a steel-bottom plate, and very stronglybound on the outside. The jackets are made of the best flangesteel, having either welded or riveted joints, and are bracedbetween the front and back sheets by our special steel stays. November, 1905.] ELECTROCHEMICAL AND METALLURGICAL INDUSTRY. 443 No rivet heads appear anywhere on the front sheets. All jackets are provided at their sides with heavy steel lugsand bolts for binding them to the adjoining jackets, and theentire set of jackets is bound together by strong steel bindersencircling the jackets, or by jackscrews, resting against themantle frames or a binding frame provided for that purpose,encircling the furnace outside of the main columns. Suitable tuyere openings are provided in the side jac
