A newmethod has been devised for operating the chuck wedgewhich not only makes the chuck easier to operate but in-creases its gripping power. The bar feed head travels ontwo parallel bars, the outer ends of which are supported ina rigid stand. Extensive and complete tool equipment forboth bar and chucking work are designed for the Fosterturret lathe. Fig. 1 shows a few special chucking toolsmounted on the turret head, but Fig. 4 shows the ones mostcommonly used. The machine can be driven either from a coimtershaft orby means of an individual motor, which is usually mountedon the back ledge of the machine where it wnll be out ofthe way. .\ special study has lieen made of the method.

Two of an order of twenty for the Swed-ish State railways were received the first week in March,and the other eighteen were promised before April 1. Thescarcity of brass and copper in Germany is evidenced bythe fact that nearly all locomotive parts usually made of thesemetals are made of iron or steel in the locomotives alreadyreceived. The Swedish State railways have also closed acontract with the German steel trust
