. Railway age . Boring Non-Parallet Cylinder Chambers. machines produce very excellent work. But the examples thus farconstructed are heavy, ponderous affairs, costing a great deal forthe weight of metal in them alone, and they do not have the uni-versally wide range for accommodating all classes of locomotivecylinder boring that should be a requisite in modern machines forthis purpose. Their flrst cost is high, and the best results are notalways obtained from them, not to of the relative large amountof shop room required. At the Topeka shops of the Santa Fe there has been built acylinder boring mill which will answer all requirements in boringcylinders for all classes of compound engines. This machine isalso adapted to bore cylinders on engines which have one cylinder.

This table has an elevating movement of:17 In. and a cross tnivel of 35 In. The table, which has the crosstravel movement, has also a swiveling motion by which a rangeof 15 deg. incline may be had.
