Thebearing for the ram is SO^-inch by 10-inch, and attention isdirected to the manner in which the slides for the same over-bang, especially in front, giving the tool increased stiffness. The ram design is original with the builders. The archconstruction brings the maximum section of metal into serv-ice at the point where leverage is greatest, i. e., when thecutting tool is in its extreme forward position. Length ofstroke and position of ram can be changed witbout the ope-rator leaving the work, and while the tool is in motion orat rest. The rail is extremely heavy. It lias 9 ins. front and 1%- I H.
