The tool loadsare thus transmitted directly through theface plate and drivers without imposingany pressure upon the spindle front of the openings in the turrets,for the forming tools, is made with aslight taper, to fit which a correspondingtaper is provided on the tool tools are thus accurately centered andsecurely held against side motion. Thisalso permits a reduction in the size of thetool body without decreasing the broadbearing surface which supports the toolnear the cutting edge. The power is transmitted to the faceplates from the long driving shaft throughtwo reductions of gearing, and not di-rectly from the shaft itself. This ar-rangement, in connection with the largediameter of the ^haft, produces a drivewhich is free from all tendency to chat-ter. The spindle caps on the heads are. VIEW OF LATHE SHOWING TURRET TOOL HOLDERS AND BENCH. are not subject to frequent renewals, andmay be conveniently made with shortshanks. The turrets are mounted on sliderests which are very heavy and low, car-ried on a bench adjustable by racks andpinions to suit the diameters of base of the slide rest is arranged toswivel on the bench to suit the angle ofthe wheel tread. The slides are each pro-vided with a feed ratchet, the connectionsfor which are fitted with ball joints. Aconvenient micrometer screw and stop onthe side of the cross slide enables thewheels to be rough turned to the samediameter without calipering. The stopcan be swung aside while finishing. The lathe is thoroughly well built inevery respect. It is exceedingly massiveand of great weight. The bed is broadand of unusual depth, forming a veryrigd base. The pinions for driving theface plates are placed in ne
