The several lines of steel I beams overhead, above de-scribed, all terminate in an overhead transfer carriage. FIG. 2.—A CORNER IN THE MACHINE SHOP whereby any or each of the several trolleys can be carriedwhile loaded, from one pit to another, or to a great manyother parts of the shop which are reached by other linesof single steel overhead I beams and trolleys with hoistsattached. At the 100-ton wheel press, one of the lines leading fromthe pit transfer has its transfer in the radial length of Ibeam, which is pivoted on the track end, the other end be-ing mounted on a small trolley made to travel in the arc ofa circle upon another I beam placed crosswise overhead,to which the radial beam is directly attached by meansof the trolley mentioned. Another circular beam, andanother transverse trolley support the I beam in aboutthe middle of its 16-ft. length. A novel method of supporting the wooden trusses wasadopted. Outside of the building, at places where the oldwalls had fallen, pilasters were built to sustain the endsof the trusses, which were built right into
