These micrometers are regularly furnished witha clamp ring which clamps the spindle and preserves thesetting. A feature of the micrometers is the rectangular shape ofthe frames which gives greater measuring capacity thanframes of the circular type. Holes are used in the largersizes to lighten the frames.

August, 1922 RAILWAY MECHANICAL ENGINEER 481 parts of the Rex line are similar to the parts of the regularBrown & Sharpe micrometer calipers. Cleans are providedfor adjustment for wear of measuring surfaces and screw. In the larger sizes, Rex micrometers are supplied withfinished wooden cases, substantially made and affording asafe place in which to keep the tools. Radial Drill Equipped for Side Rod Boring AN interesting side rod boring operation is performedon a 6-ft. plain, triple purpose, radial drill built bythe American Tool \\orks Company, Cincinnati,Ohio. The slow speeds for this and similar boring and tap-ping operations are obtained through an internal gear drive
