Michigan Central Railroad. The accompanying engravings illustrate a novel and ef-fective method of making a permanent repair upon somecracked cylinders, that was resorted to at the Jackson, Mich.,shops of the Michigan Central Railroad. Trouble was ex-perienced with breakages of the high-pressure cylinders of PIG. 65.—MOTOR DRIVE APPLIED TO NILES WHEEL PRESS. The method of repairing adopted was a very simple and ef-fective expedient, and its worth has been proven in service, asno further trouble has been experienced since these may be seen from Fig. 2, heavy wrought iron bars wereforged with right-angle bends at each end, forming fixedclamps; the distances between the jaws were made somewhatless than the lengths of the cylinder castings outside. Thebars were then heated and slipped, while red hot, over theedges of the castings as shown in Fig. 2; when cooled theyshrunk onto the casting so tigh
