The result wasnot only a saving in time, labor and material, but a strength- ening of the frames at the points welded. After the weldswere completed and the deck casting put in place, it wasonly necessary to ream out the holes and rebolt the welds were made by J. W. Boyd on April 6, 1920, andthe locomotive has since been in constant service. TRIPLE VALVE GRINDING MACHINE The device illustrated was designed to eliminate the laborof grinding triple valve slide valves. As shown, the valveis arranged to be held on a stand on the air brake grinding compound is applied to the slide valve andit is then placed in position on the valve seat. An eccentricwith a crank arm and crank is driven bv means of a light
