. Railway mechanical engineer . swing inside the water guard is 6 in.,while without the guard, it is 10 in. The work-head isdriven by a cross belt through the base from a cone givingthree speeds of 160, 290 and 530 It is arranged toswivel and is graduated to 45 deg. or 4 in. taper per rotation of the work head and the pump is automatic-ally and quickly stopped as the grinding wheel is drawnfrom the work. The feed to the cross slide is calibrated to read to one-half thousandth of an inch on the diameter of the c?n be operated by power or hand as desired. The main table has flat and V ways and is very rugged for thissize machine. The travel of the table can be either by power,reversing accurately at any point desired or by hand feedwith the power thrown out entirely. A two-step cone drivegives two speeds of travel with the power feed. The wheelhead has a solid adjustable taper bearing at the wheel endwith ball bearings at the pulley end. Various holding fixtures have been designed and can be. Cross Section Through Wheel Spindle furnished on order. The one usually supplied and givingthe largest range consists of a quick acting collet chuck withjaws, having a capacity of Y% in. diameter up to 3 is operated by a lever with an adjustable compensatingdevice which prevents the work from being distorted frompressure. In railway machine shops, the Heald No. 80internal grinder would be of particular value for such workas grinding hardened motion work bushings made in quantityto be carried in stock and later fitted to valve motion levers. Fundamental Principles of Handling Men In a talk to foremen published in Industrial Manage-ment, George D. Halsey lays down the following principlesas requisite for securing best results in handling men: 1. Delegate and supervise the work. 2. Keep compensation fair and strictly proportional tooutput or general value to the company. 3. Study each individual carefully and fit the methodof handling to the individ
