The illustration shows that the motor is wellup from the floor, away from dirt and chips, but not highenough to make the machine top heavy. An adjusting nuton the back of the motor drive housing is provided for ad-justing the friction clutch for the main drive. By this new development, all the advantages of individualelectric motor drive are secured not only for users of newNo. 1 and No. 2 Cleveland milling machines but for thosealready operating belt driven machines. The time and ex-pense required for changing over will in many cases be farless important than the elimination of belt troubles and themore convenient placing of the Milling Machine Arranged for Electric Motor Drive Wood Turning Lathe of Unusual Length THE wood turning lathe illustrated herewith was built inaccordance with specifications written for the UnitedStates Government during the year 1919. The lathewas designed for the turning of spars or ship masts and hasa swing of 32 in. and a bed 62 ft. long.
