Surface Planer
All Resolutions
Description:
Three-quarter view of a double surfacing planer supported by six stout cast-iron legs. A spoked drive wheel is visible on the near side, connected to the mechanism enclosed within the central frame. A roller assembly sits above the planer bed, which extends toward the right. The following details are provided by the catalogue description:
[This machine] is intended for large planing mills, bridge, railroad and car shops, and wherever a heavy and substantial machine of large capacity is desired [...]
The cylinders are belted on both sides, have three knives, steel lipped chip breakers and wearing edges, large steel journals with long and self-oiling bearings all perfectly balanced. The line of the bed being in a fixed position, the upper cylinder is made to adjust to the thickness of the lumber.
...The upper cylinder is carried in stands, planed in and gibbed to the sides of the machine, and is raised and lowered by screws, connected by gearing worked by a hand wheel. The pressure rolls are raised and lowered with the cylinder, and supplied with our patent folding and weighted levers, allowing the rolls to operate independently or together, to accommodate the thickness of the lumber.
The under cylinder carries three cutters, has combined boxes, secured to a heavy yoke, which can be instantly raised or lowered to suit the work, by simply turning a crank, and is made easy of access by swinging the table in front entirely out of the way by the removal of one bolt, both upper and lower pressure bars having independent adjustment.
