  • Patent number: 4485859
    Abstract: A planer adapted to be mounted on a multipurpose woodworking tool which includes a housing, a rotating blade driven by the headstock of the tool, and a vertically displaceable table mounted beneath the blade. The table is supported by a plurality of jack screws mounted on the housing and attached to the table by connector nuts which eliminate binding as the table is raised or lowered. The jack screws are driven by a chain drive having an adjustable idler sprocket which permits the chain to be disengaged from a selected jack screw to allow it to be rotated to level the table. Vertically displaceable feed roller assemblies are attached to the housing and each includes a sprocket meshing with a common drive sprocket with sufficient engagement to be driven throughout the vertical displacement of the rollers. A chip removal hood is mounted on the housing and has an exhaust nozzle adapted to receive a vacuum cleaner hose. The planer is releasably mounted to the woodworking tool by a pair of clamps.
