A heavy bar measuring about 6 in. by2 in. is bolted across the engine fromframe to frame in Jine with the holes tobe bored. To this is bolted the frame ofthe machine, which is made from an oldengine truck oil box, the two legs ofwhich are bored to carry the boring leg is faced oflf to take the thrust. Outside of this is the feed consisting ofa worm and gearing, as shown in the illus-trations.

GEARING FOR DRIVING BORING BAR FOR EQUALIZER RAILWAY CHUCK FOR PLANING ROCKER & HUDSON CO. vertical portion of the base carries a 2}/in. bolt E over which the two conicalwashers C C are slipped. The bolt isrigidly attached to the base, and, after therocker box has been fitted and the two EQUALIZER WITH BUSHED PIN RAILWAY parts bolted together, it is slipped overthe bolt and squared and held by theconical washers, which enter the hole ofthe rocker bearing. In setting up the work it is merely nec- wear, and when they wear the pins mustbe renewed and the holes should be re-paired in some way to save the expenseof a new equalizer. The problem has beensolved in a very efficient manner at theSomerset, Ky., shops of the Southern simply making a new pin of the orig-inal dimensions and then boring out theholes in the equalizer that have worn ob-long. The holes are bored out to a stand-ard size and then bushed back to theiroriginal dimen
