EFFICIENT shop devices that have worked out well inactual practice in the San Bernadino Shops of theAtchison, Topeka & Santa Fe are shown in the accom-panying illustrations and described below. Clamps Used on Tire Boring Mill In boring the largest tires for passenger locomotives, it was found a difticult task to clamp them to the borin mill Facing Steam Pipe Joints At one time in railroad slioj) practice it was thought ad-visable to make up all steam and exhaust pipe joints usingwhite lead. Under the action of higli temperature steamover a considerable period of time, this white lead acted onthe joints to make them very rough. The result was thatthey often required machining before being ground in andthis work was fomierly done at San Bernardino on a hori-zontal boring bar, already overcrowded with work. To relieve the boring bar of this work, the tool illus-trated in Fig. 2 was designed and the machine operation. table owing to their large size. Before making the clamps,shown in Fig. 1, bolts and blocks were used, requiring con-siderable time for the set-up and not holding the tires obviate this difficulty, special clamps were forged withT-heads to fit the in the boring mill table, the clamps Fig. 3—View Showing Use of Guide Adjusting Block can now be performed on a radial drill press. As indicated,the tool consists of cutters suitable for flat seats or balljoints, the cutter in either case being guided by a spider orpilot block adjusted to any desired position by the use ofset screws. In operation, the spider is set in the steam pipe
