Mr. William J. Taylor, of Round Brook, N. J., has pat-ented a method of manufacturing car-wheels, of which thefollowing is a description : In the production of a wheel of my invention, shown byfig. 10, the rinli. rim, or hoop to constitute the tread a is madeof forged or rolled steel, and preferably of a composition ortemper that will not flatten in service, and also that will give. JOUGHINS RAILROAD CAR-TRUCK. good resistance to wear ; and the flange is made of cast iron,as well as the body of the wheel, the flange being chilled inorder to resist tendency to curve-wear in use. The mode of making a car-wheel of my invention isas follows : A ring, hoop, or tire of required dimensionsand of substantially uniform thickness throughout, as illus-trated in fig. 10, or slightly thicker on the edge or side nextthe flange, to constitutethe tread of the wheel, isprovided and is heatedto required temperature,so as preferably to bewelded to molten castiron in order to form thebody and flange of thewheel. This ring, hoop,or tire a is then intro-duced into a mould justbefore the metal to con-stitute the body andflange of the wheel ispoured. The molten ironby such operation isfused or welded to thehot steel rim or tire, toform with the same onesolid structure, while thefiance of the wheel ischilled at the same time. It may be here rema
