The modern electroplater; a complete book considering fully the elementary principles of electro deposition of metals, their practical application and industrial use . aking it possible to continue opera-tions without moving from the wheel.

Power for driving the machinery may be suppliedby a motor of the correct capacity and speed. If themotor is located in the polishing room, dust-proof orprotected bearings should be provided. It is seldomnecessary to provide a motor for each machine; powermay be transmitted to a number of machines throughline shafts and counter shafts. THE MOTOR-DRIVEN LATHE The most simple type of polishing or buffing latheis direct motor-driven, the armature shafts, extendedbeyond the bearings, serving as the arbor for thewheel. This extension may be made on either or both. Fig. 107.—Polishing and Buffing Motor Lathe(General Platers Supply Co.) sides of the motor. Particular care must be exercisedin the protection of the bearings and commutatoragainst the injurious emery dust from the wheel. Afully-enclosed motor, as illustrated in Fig. 107, shouldbe secured, if possible. It will be noted that even 196 The Modern Electroplater the oil holes and cups are omitted, self-oiling bearingsbeing used. The advantage of this single unit machine is ap-parent. It may be placed where most convenient, ona bench or on a column, without regard to locationof overhead shafting. Again, such units may beadded to the equipment without causing a drain uponthe existing power plant. THE BELT-DRIVEN LATHE Belt-driven lathe heads form the standard equip-ment for many polishing rooms. According to theshop requirem
