Key to Links for Patent Information

USPTO = U.S. Patent Office . Images of the actual patent can be viewed on the U.S. Patent Office web site but a special TIFF viewer must be installed with your browser in order properly work. More information on how to configure your computer to view these patents can be found at TIFF image Viewers for Patent Images.

Patent Number Date Title Name City Description
339,606 Apr. 06, 1886 Knife for cutter-heads John H. Wells New York, NY "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".
