What is Probably the greatest layoff which ever occurredin the transportation industry took place between August, 1°20,and March, 1921, when, according to the statistics of the Inter-state Commerce Commission, the total number of employees onthe Class I railroads decreased from 2,197,824 in August, 1920,to ,068 in March, 1921, representing a decrease of 604,756,or per cent. From a circular issued by the Diami nd Saw & Stamping Work*. Buffalo, X iiernicc Odilcr Heavy Pattern 90-In. Driving Wheel Lathe MODERN facilities for wheel turning, quartering andjournal turning are combined in the heavy pattern90-in. wheel lathe, illustrated, which has been de-veloped recently by William Sellers & Co., Inc., Philadelphia,Pa. As usual in this type of lathe, the left-hand head isbolted to the bed in a fixed position, while the right-handhead is adjustable for putting in and taking out the mountedwheels. The adjustment of the sliding head is accomplishedby a motor, driving through a slip clutch to insure the properpressure being put upon the lathe centers. This also pro- diameter wheels. This feature is important in eliminatingdeflection and chatter. All of the tools necessary to complete the turning, fromroughing to form finishing, are assembled and carried inturrets mounted on top of each tool slide as order to release the clamp and lock for the turret, prepar-atory to bringing a set of tools int
