The pressure bar in front of the upper cylinder is dividedand adjustable to and from the cut, and has chilled toes, re-ducing wear to a minimum. The bar behind the cut is ad-justable for difference in thickness of material worked. Thebars in front of and behind the lower cylinder are adjustableto and from the cut, and are vertically adjustable for varyingdepths of cut. The bar over the lower cylinder is adjustable. Six-Roll Double Cylinder Planing and Matching Machine,J. A. Fay & Co. nals 2>4 inches in diameter, and runs in self-oiling bearings10% inches long. The cylinder-raising screws are outside ofthe frame and are fitted with ball bearings and a device forquickly taking up all lost motion in the screw caused by thewear of the threads. The lower cylinder is mounted in a heavyyoked frame, has 2i/i-inch journals that run in self-oiling bear-ings lOV^ inches long, and is vertically adjustable at eachend. The matching works are heavy. The arbors are of steel 1%Inches in diameter where the cutter-heads are applied, and re-volve in long bearings, both of which are adjustable verticallyand horizontally, and are i-igidly locked in any desired posi-tion by a lever conveniently located outside the frame. Thetop plate of each matcher hanger is detached from the maincasting for convenience and economy. The machine will matchstock from 2 to 30 inches wide. Th
