IMPROVED CIRCULAR RE-SAWING MACHINE AND SIDING SAW
Our engraving is a representation of a re-sawing machine, to which was awarded the first medal and diploma at the Exhibition of the American Institute for 1870. The award was made with discrimination and justice, as the machine is undoubtedly one of the best of its kind.
A prominent feature of the saw is that the feed rolls may be set inclined to the saw, so as to saw siding. This adjustment is made simultaneously for all the feed rolls by inclining the table to which they and their gearing are journaled, a set screw holding the table when set, and a simple adjustment compensating for what would otherwise be the increased tension of one of the belts when the table occupies this position.
The feed rolls have an adjustable speed motion through the use of a system of cone pulleys intermediate between the first pulley, from which motion is carried to the feed, and the last, which imparts motion to the gears of the rolls. They are also self-centering, so as to guide the stuff for uniform thickness through all inequalities on each side of the saw; or they may be made not self centering, and may be held in a fixed position by the adjustment of a single screw.
The machine is constructed in a very substantial and workmanlike manner. It was patented February 2, 1870, and is manufactured by John B. Schenck’s Sons, the manufacturers of the celebrated Schenck’s planers, at Matteawnn, N. Y. The salesroom are at 118 Liberty street, New York, where the machine may be seen and the firm addressed.
Note: The patent date is wrong. It should be patent #99,600 granted on 08 Feb, 1870. |
