. Railway mechanical engineer . Wheel Drive and Elevating Mechanism ball bearings each way, adjustable endwise for any wear. It isstated that machines have been run constantly for eight yearson hard work, with bearings thus constructed, and have given,the best of satisfaction. The grinding wheel is made up of 14sectional blocks forming a wheel 32 in. in diameter, 8 Heavy Duty Face Grinder With Traversing Column and Grinding Wheel February, 1921 RAILWAY MECHANICAL ENGINEER 127 deep, with a cutting rim 4 in. thick. An open space is pro-vided between each section for material ground off to workinto, as is common with metal-working tools. The motor ontop of the upright column, designed to operate the grindingwheel head up or down through spur and worm gears, is back-geared down to a practical speed for the elevating screw. Ashifting lever operates the gears to move the wheel head upor down as desired. A suitable cast iron guard covers the gears on the motorand grinding wheel spindle. There is a 5 in. lead screwthrough the center of the entire length of the bed, connectedat the left hand end to the 7,i-hp., motor through a chaindrive and a train of spur gears to get the right reduction ofspeed between the screw and the motor. There is in thistrain a toothed clutch operated by the shifting lever to revolvethe lead screw in either direction to make an
