The engineis on wheels, making the whole deviceportable and easily moved about the counterpart of this engine, also drivenby air, is used with a cold saw for squaringup the ends of heavy work. Another rather novel use for compressedair was seen here, in the way that oil wasfurnished several tools. A 12 x 33-inchauxiliary reser\oir was placed on end andused as an oil tank. The pipe from airsupply was tapped into top of tank, fromwhich pipes were led to the bolt cuttersand nut tappers, the pressure on the oilbeing regulated at the tank, and the vol-vime of flow handled at the is said to be superior to the old ma-chine pumps, in that it is cleaner. The. floor around the tools seemed to bear outthe claim. An inquiry about the compressor fur-nishing the air for all these purjioseselicited the word Westinghouse. Thereare three pumps—two compounded—anda good reservoir capacity to draw are still looking for places where aircan be used to advantage. Among the new wrinkles for loweringthe cost of work was their way of gettingup valve-stem glands. First, the glandswere chucked, bored and threaded onouter end, in lots of twenty or more ; theywere then reversed and the threaded partscrewed on a special chuck that was fittedto the lathe spindle, and taking the place ofthe face plate. While on this chuck theglands were turned for the .stuffing-boxfit and bored, with one roughing cut, 556 leaving merely a scrape for a reamer usedto bring them to a uniform size and were then readv for the babbitt, andtaken to another special rig
