Description: |
| "This invention of improvements in wood-planing machines has reference to machines for planing boards; and, in the first place, to the arrangement of the cutting instruments, whereby the wood is planed and smoothed; and secondly, to the method of weighting the wood under operation, for the purpose of keeping it steady and to its work. The first improvement consists in disposing the different tools or plane-irons at inclines or angles to the surface to be operated upon, best adapted to the kind of cut which each particular tool is to take. The angle of the tool for removing the rough outside, differs a little from that at which the smoothing tool or iron is placed; while tools placed intermediate of those two are disposed at different intermediate angles, according to the kind of cut they are intended to take, but are all set at a much more acute angle than that heretofore used in planing machines. The second part of the improvements consists in applying rollers or pressers separately weighted and independent of each other, to keep the wood in proper contact with the cutting tools while being planed, so as to produce a better and more uniform bearing on each individual tool than is obtained by the ordinary method of weighting and working these rollers or pressers."This patent was cited as prior art in the 1883 lawsuit involving an alleged infringement of a patent granted to James Goodrich and Henry J. Colburn (USA patent 111,632, reissued as RE8,438) and assigned to William H. Doane of J. A. Fay & Co. |
