Wheels used on the standard machinesare 16 in. diameter up to 3 in. face; wheels used cm theheavy drive are 18 in. up to 4 in. face. The table drive is of a simplified type, eliminating whatwas formerly known as the table transmission. This driveconsists of a single unit contained in the bed of the machine,which is a combination of table drive and transmission. , and four table feeds from 22 iii. to 14 in. per min-ute. The feeds and speeds arc entirely independent of eachother. The new sizes have the single constant speed drive used on the larger machine-, which reduces the COSt whenequipping the machines with End View, Showing Main Drive and Pump All-steel spur gears are used for the reversing power table traverse is controlled by a lever imme-diately to the left of the table hand wheel, which providesfor starting or stopping the table at any point in its stroke.\\ hen the table is under power the hand wheel is auto-matically disengaged, and when the power is removed thehand wheel is automatically engaged for traversing thetable by hand. There are four table feeds, derived from asingle unit gear box, and controlled by a lever at the rightimmediately below the table hand wheel. The automatic cross feed is positive in its action and issimplified without losing any of its features. This can beset for a reduction of any amount from .0005 in. to .005 either or both ends of the table reverse. This latter fea-ture is especially advantageous when grinding against ashoulder. The feed is automatically thrown out when workis ground to size and a positive st
