The machine is entirelyself-contained. The cast-iron spool holding fifty to sixtypounds of band wire is mounted on the frame, windingcenters being supplied to fill the spool in the lathe from alarge wooden reel, which operation takes but a few min-utes. The machine may be used in connection with the Peer-less banding machine or an ordinary lathe. It may bebolted to wall or as it is provided with casters may be quick-ly and easily placed in front of a banding machine or lathefor use, and then pushed under the work bench or any place. COMBINED TENSION AND BANDING MACHINE in the barn where it is out of the way. The large drumwhich is used for the tension on the magnet wire in con-nection with the field-coil winding is applied to the machinewith three cap screws, the same excellent feature apply-ing as when used for band wire. The machine in brief,consists of two side frames mounted on angle-steel sillsand- casters. The lower shaft runs in babbitted bearingsand one end carries the brake pulley. On the other end isa pinion which engages with the gear on the upper shaft,this ratio being 3 to 1. On the gear is mounted the largedrum for insulated wire and on the shaft the taperedflanged band-wire drum. The taper is so designed thatthe tendency of the band wire to crawl up is neutralized bythe tendency of the taper to slide down. Six or seven turnsof the band wire on this drum will hold any tension the front end of the frame is mounted the cast-iron wirespool with the small retard
