ABSTRACT:
A planer of the type adapted to be mounted on and driven by a multipurpose woodworking tool includes a housing, a rotating blade member, and a table mounted beneath the blade member and vertically displaceable relative thereto by a plurality of jack screws. The jack screws carry connector nuts having outer members attached to the table which allow relative sideward movement between the table and screws to minimize table binding. A chain drive engages the jack screws and includes an idler sprocket which can be adjusted to allow adjustment of an individual jack screw to level the table. First and second roller assemblies upstream and downstream of the blade member are rotatably mounted on the housing and are vertically displaceable; the roller assemblies are driven by a single, fixed drive sprocket which is capable of rotating the rollers throughout a range of vertical displacement. A chip removal hood is mounted on the housing and has an exhaust nozzle adapted to receive a hose of a vacuum cleaner to draw chips through the hood. A pair of clamping members are attached to side walls so that the blade member and an output shaft of a head stock of the woodworking tool are coaxial, whereby a coupling member may be used to transmit rotary power therebetween. A switching device includes a master switch that controls the flow of electric current to both the head stock and the electric motor driving the feed mechanism, and includes a key-operated locking mechanism.
