In the design great care has been taken toarrange the details to facilitate operation and inspection. UNDERWOOD PORTABLE BORING BAR. NEW PLANER CONSTRUCTION. The J. A. Fay & Egan Company has recently placed on themarket a new device consisting of a patent sectional clamp bearingfor cylinder journals, which the company is now placing on itsNo. 156 single-cylinder planer. The X-ray view shown will give an idea of this of the cap bearings is made up in two sets of thin babbittmetal plates, five to each set. The edges of these plates In contactwith the journals are turned on a lathe to describe the circum-ference of the lower bearing. They rest diagonally upon the upper ^l. ^. Sectional Clamp Bea surface of the journals and exert no pressure downward except thatproduced by their own weight. By simply loosening the clampbolts and pressing the plates down by hand, all looseness of thejournals from wear may be taken up each day. No packing orliners are used. The manufacturers state that no matter fromwhat direction the machine is belted there is no heating of theboxes and there is never any occasion to scrape and rebabbitt thebearings, tor the babbitted plates take up their own wear. Circulars giving all details of_ every part of this tool and show-ing two views of the machine may be had on application to themanufacturer. The accompanying engraving illustrates the portable boringbar manufactured by H. B. Underwood & Co., of Philadelphia,which is designed for general cylinder boring. The bar can beoperated in a space no larger than that needed to remove thepiston from the cylinder, and by its use the reboring can oftenbe done in place
