There is perhaps no problem in connection with locomotiveengineering, if we except the valve-gcariug on which so muchingenuity has been exercised, as on that of providing a flexibledriving-wheel base. By that is meant an arrangement ofdriving-wheels which will permit them to adjust themselves. prt a? nags SALVETERS METAL DRAFT-SILLV] to the sinuosities of curves and assume radial positions in rela-tion thereto. A very large number of such inventions havebeen proposed of varying degrees of practicability and im-practicability—chiefly the latter. Messrs. Richard Klein andRobert Lindner, of Chemnitz, Germany, have recently takenout an American patent for an ingenious arrangement, whichis not without some promise of success. Fig. 1 is a transverse section on the lines t c and v id of fig. 3,which is a plan of the running gear of a six-wheeled coupledlocomotive. Fig. 2 is a transverse section in the middle of theleading axle on the line x y of fig. 1. The invention relates to what is called in the specifications displaceable axles. In the illustrations herewith only onesuch displaceable axle—the leading one—is shown, but theinventors describe an engine in which both the front and trail-ing axles are arranged in this way, and the i
