The knee, table and saddle are counterweighted by means of weights inside the column. Easy vertical adjust-ment of the work in relation to the cutter makes an auxiliaryvertical slide for the spindle unnecessary. The table has aworking surface of 70 in. by 18 in. and a longitudinal rangeof 42 in. Table wear is taken up on adjustable taper gibswith locked adjustment. Face milling cutters may be drivenin either direction and the spindle nose construction permitscutters to be set up or removed easily. A spindle reverse hasbeen incorporated for the reason that, in order to get cutting. Kempsmith No. 4 Vertical Type Maximiller strains in the ))ro])er direction on the gilis and tables, a facemill must be run in the opposite direction to a spiral or slabmill. The spindle reverse of this machine is controlled by asingle lever conveniently located. The No. 4 jSIaximiller is arranged with power quick tra-verse, giving a 100-in. ])er min. travel of the table in eitherdirection and a vertical movement of .16 in. per min. control is concentrated, and it is unnecessary for theoperator to change his position in operating any of the quicktraverse and feed movements. In case of error on the part ofthe operator in engaging wrong levers, the machine is amplyjirotected by safety devices. Eight changes of feed are provided, ranging from ^ in. to25 in. per min. in geometrical progression. The gears areall heat treated and proper safety devices are incorporatedthroughout to prevent exceeding the maximum safe load. Par-ticular attention has been paid to the question of lub
