Abstract:
A reciprocating saw comprising:a housing; a spindle mounted for reciprocation relative to said housing, said spindle having an end adapted to support a saw blade; a motor for moving said end during a first cutting stroke and during a first return stroke, said end being movable along a first path of travel relative to said housing during said first cutting stroke and during said first return stroke; and means for selectively changing said first path of travel of said end to a second path of travel relative to said housing, said end being movable along said second path of travel during a second cutting stroke and along said second path of travel during a second return stroke, said second path of travel being different than said first path of travel; wherein said changing means includes a track and a track follower, one of the track and the track follower being connected with said spindle, wherein, during said first cutting stroke, said track follower moves along said track, resulting in motion of said end along said first path of travel; wherein, during said second cutting stroke, said track follower moves along said track, resulting in motion of said end along said second path of travel; and wherein the saw blade is selectively supported by said end in a first orientation relative to said spindle to have a first cutting direction and in a second orientation relative to said spindle to have a second cutting direction opposite the first cutting direction, wherein said first path of travel is characterized by movement at least partially in the first cutting direction during said first cutting stroke, and wherein said second path of travel is characterized by movement at least partially in the second cutting direction during said second cutting stroke.
