The 1907 conventionwill be held in Montreal, NEW SPRINGFIELD 14, 16 AND 18 INCH LATHE WITH DOUBLE BACK GEARS. NEW SPRINGFIELD ENGINE LATHE. A new line of standard engine lathes, 14, 16 and 18 ins.,equipped with three-step cones and double back gears, thusfurnishing eighteen different spindle speeds in connectionwith a two-speed countershaft, and making it possible to useexceptionally wide belts for lathes of these sizes, has recentlybeen placed on the market by The Springfield Machine ToolCompany, Springfield, Ohio. The back gear ratios are 3 to 1and 9y2 to 1, and this, with a 314-in. belt on the 16-in. latheand a 3%-in. belt on the lS-in., furnishes sufficient power totake care ef the heaviest work within the range of these ma-chines. The wide range of spindle speeds, a convenient feedarrangement and the powerful drive make it possible to turnout quickly and accurately either light or heavy work. The spindles are of large diameter, and are equipped withring oil bearings, which may be replaced with
