  • Patent number: 5383275
    Abstract: A hand planer comprises a housing, a planer head supported in the housing, a motor driving the planer head, a fan blower connected with the motor for generating a flow of air for moving chips, a chip ejector, two air guidance ducts through which the flow of air is guided from the fan blower to the chip ejector, a chip conveying duct having a chip discharge opening such that planed chips exit the chip conveying duct through the chip discharge opening, the chip ejector accommodating both the chips and the flow of air, and guides for guiding the flow of air in a switchable manner to the chip conveying duct via one of the two air guidance ducts. Therefore the problem of ejecting the chips in a preselected direction with extreme precision and high efficiency is met.
