In overflowing the oil lubricatesthe table gear and pinion as well as the bearings. The control is centralized, and the convenient arrange-ment of control handles, which is indicated in Fig. 1. addsto the productiveness of the machine.

The ability to use large amounts of cutting lubricantwithout the possibility of its entrance into the machine itself,is an item of considerable importance which has been keptin mind in the design of ever}- detail and is the result of aseries of experiments extending over a period of four years. Crank handles on shafts revolved at high speeds to obtainrapid traverse of the head are dangerous and have beeneliminated. Patented hammer handwheels. shown in Fig. 4,which put lost motion to good use and eliminate all danger,actually increase the operators atiility to obtain fine settings of the tools. The clearly graduated scale mounted onthe tool slide gives the coarser settings and micrometer dials,
