Description: |
| "This invention relates to an improvement in double siding-machines, whereby logs, ties, &c., are flattened on two sides at one operation; and more particularly the invention relates to that class of siding-machines which are used in saw-mills for canting logs for stocking the gang, such machines being commonly provided with circular saws; and the invention consists, primarily, in two rotary movable disks securely fastened upon their respective shafts, which are journaled in frames located equidistant from the center line of the log-chain, on either side thereof, the said disks being provided with knives or cutter, whose cutting-edges project slightly past the face of the disks and extend backward sufficiently far to cut the necessary width of timber from the opposite sides of a log during its passage between the disks. These cutting-disks are moved laterally toward or away from each other with a uniform motion, in order to suit whatever thickness it is desired to leave the log after its sides are flattened, this movement of the disks being accomplished by means of a rod extending across both of the above-mentioned frames, provided on either end with hand-wheels and connecting by suitable mechanism with the shafts which carry the disks, so that the rotation of the rod may impart an endwise motion to the disk-carrying shafts, for this rod is screw-threaded throughout portions of its length near each end, the portion near one end being cut with a right-hand screw, awhile the portion near the other end is cut with a left-hand screw. Suitable nuts having pins on each side are arranged to travel on these screw-threaded portions..." |
