Railway and Locomotive Engineering . , they are simply driven out andnew ones put in their place: so that, whenthe bars have once been bored they aredone with for the balance of their life. These bushings always last from oneshopping to the next and frequently inL jnu IDT -lur REDUCING GEAR FOR MOTOR DRIVE taper shank of the spindle of the last gearof the train. The air motor is being extensively usedfor all sorts of purposes. One is the August, 1921 RAILWAY AND LOCOMOTIVE ENGINEERING 217 grinding of the joints between the cylin-ders and their heads. The arrangement used for this consistsof a spindle having a taper shank, for tak-ing the air motor, and a pinion driving a the largest boring mill available. In theSomerset, Ky., shops of the Southern condition was encountered wherebushings 27 in. in diameter and 42 in. longhad to be bored, and the largest boring and screw. The bushing is first bored andcounterbored on a lathe to vihich thischuck is fitted. The two ends are thenclosed with two cylinder heads that are. GEARING FOR GRINDIXG CYLINDE spur gear which is keyed to a crank drives a connecting rod that iscoupled to the head. The head, to be ground, is put in placeand a crossbar or arm is bolted to it asshown on the engraving. The connectingrod is attached to the projecting end ofthe crossbar and gives it an oscillatingmotion which is continued until the seatis ground. * * * Another use is ihat of pulling cylinderbushings into place. The bushing is entered at one end of thecylinder and a crossbar or plate is putacross the outer end. The center of theplate is threaded to take a screw of 2J4in. diameter. The other end of the screwpasses through a head at the far end ofthe cylinder and has a collar which takesthe thrust against the head. The screw is SOUTHERN RAILWAY #
