Description: |
| "The object of my invention is to provide a plow or analogous wood-working tool in such manner as to cause it to make a clean square cut when straight downward cuts are desired, and when applied to a cutter employed on a cutter-head will avoid heating and discoloration of the wood by friction."My invention consists in providing such plows or cutter with a narrow rib on the face in line with the part of the tool at which the straight downward cut is desired."It also consists in a cutter having the working-face side wider than the other, and having such face provided with the rib at the point of straight cut, as before stated."It also consists in a cutter inclined inward slightly from the cutting-edge toward the body of the tool."A reported example is labeled, "McDERMOTT BRO'S & LOW NEW YORK WELL'S IMPROVED". |
