. American engineer and railroad journal . a removable partition atthe middle into two parts, one for soft and one for hard does away with the usual coal and coke boxes, and allowsfree access to the forge from both the sides and the end. Theouter end of the top of the forge is partitioned off to hold thegood slack left when tearing down the fire. The space betweenthe backs of the two forges is occupied by tne blast valves andby shelves for holding small tools. The hood and the piecewhich connects it to the blast pipe are of cast iron. The forgeswere designed and patented by Mr. McCaslin, and are manu-factured by the Monessen Foundry and Machine Company, ofMonessen, Pa. The rather high blast pressure of 14 ozs. is used, and theadvantage of this can best be explained by quoting from a paperon The Ideal Blacksmith Shop, read by Mr. McCaslin beforethe recent Railroad Master Blacksmiths convention. Thewriter, through experience, has determined to his own satis-faction that any volume that will fully supply each forge with. A carefully arranged system of single jib cranes serve thesteam hammers, and a double jib crane, No. 5, serves two of theforge fires used for heavy work. Three steam hammers areprovided; a 4,000-lb. and a 600-lb., made by the ChambersburgEngineering Company, and a 1,100-lb., made by Bement, Miles& Co. Two large circular fires near cranes Nos. 1 and 3 areused for heating heavy work for the 4,000-lb. hammer. Twosmall coke furnaces are built in the double forge to the left ofthe small bull-dozer, and are used to heat small and short workfor the bull-dozers. The pneumatic bull-dozers, a 20-ton and a100-ton, were designed by Mr. McCaslin and built at the shops,and are used for forging anything from a bolt head or hand-hold to a wrecking chain hook or heavy arch bar. The furnacesbetween the bull-dozers are used for case-hardening and forheating heavy material, a trolley extending from this pointto the large steam hammers. The large punch and shear
