The Works Of Messrs. Schneider And Co.

PLAN OF CONSTRUCTION DEPARTMENT. 97 of the usual kind of masonry work, more or less intricate, according to the requirements of the piece, the mould when finished being placed in a pit, where it is cash, after having been firmly secured by earth rammed in between the mould and the sides of the pit. The early experience of Ci’eusot in casting chilled roils became of special service at a later time. Since the use in fortifiée! works of stationary, and disappearing, armoured turrets, they have cast a very large number of chilled plates a small reverberatory furnace, a large crucible constantly in use and provided with a mechanical device for casting, and eight ordinary crucibles. The total annual output of the brass foundry is 350 tons. The moulding sand is prepared in a special building fitted with all the necessary plant for erushing and screening the varions mixtures. Sand pits in the near vicinity of Creusot supply almost the whole of the varions materials required. Plan of Construction Shops. Fig. 253. for the French Government, and for Belgium, Roumania, Holland, &c. The expérience acquired by Messrs. Schneider and Co. during many years has enabled them to succeed easily in the manufacture of these pièces, and to produce them of such a résistance that they can withstand the action of heavy fire. There are in the foundries, one 60-ton travelling crâne, three steam crânes of 30 tons ; eleven of 20 tons ; four of 15-tons; 12cupolas; and two large reverberatory fur- naces, the latter being exclusively used for melting brass for casting screws. There are besides, in the brass foundry, Smiths’ Shop.—This shop is fitted up with furnaces and steam-hammers for the working of steel ingots, the weight of which does not exceed 10 tons ; all work requiring ingots of a greater weight is ordered by the Construction works from the Steel works départaient, which is perfectly laid out for the manufacture of all heavy forgings. In the smiths’ shop there are 22 steam hammers, varying in power from 10 cwt. to 10 tons. The larger sizes of these hammers, namely, those of 10, 8, and 6 tons, with the furnaces by which they are served, are used for forging; pieces of comparatively simple shape ; they are used also for
