A novel application of electricity in the handling of iron and steel is now in operation in Cleveland, Ohio, in the way of a magnet.

This form of magnet consists of a large iron disk supported by chains, which may be fastened to the hook of a derrick or crane block. To the top of the disk is applied an electric plug device connected with insulated wires, which by an ingenious auxiliary pulley arrangement are led to a controller at some convenient point at the base of the derrick or in the operator's cab of the crane. The disk is lowered over the material to be lifted and the current turned on, and in this way enormous loads of material may be gathered together and held by the magnet as long as the current remains connected. Different forms of the disk are made for handling pig iron, heavy melting stock, such as crop ends, butts, steel risers, small castings, tin scrap, whether loose or in bales, shearing scrap, rod scrap, bolts, nuts, punches, rivet spikes, rail ends, machine borings, flats, sheets and, in fact, almost any form of iron or steel which affords a surface sufficiently large for the magnet to act upon. When the material has been carried to the place where it is to be deposited the current is turned off and the magnet at once releases the load. Scrap tin has always been an ugly form of material to handle satisfactorily, but by the use of this device it may be disposed of as rapidly and as easily as heavier stock.

At the present time all wire is made by the drawing-process, and while permitting the production of a much thinner wire than could be obtained from the rolls, it also gives a wire of greater tensile strength, so much so that the smaller the size to which the wire is drawn down, the greater is its ultimate breaking strength.
