Abstract:
1. In apparatus for cutting through a covering layer on a cable, or the like, by a circular cutting edge of a blade which is moved in an orbital path about the central axis of the cable by a drive motor rotatable about said central axis, the improvement comprising: a) an elongated rod having a first end affixed to said motor for rotation thereby and a linear axis intersecting said central axis at an acute angle at a point forwardly of said motor, whereby rotational motion of said motor is translated to orbital motion of all points on said linear axis other than said point of intersection; b) a spherical bearing through which said rod slidingly extends for transmission of said orbital motion from said rod to said bearing; c) a first member upon which said bearing is mounted for transmission of said orbital motion from said bearing to said first member; d) a second member upon which said first member is mounted by linear roller bearings extending along a first axis in a plane perpendicular to said central axis for relative movement of said first and second members along said first axis; e) a third member upon which said second member is mounted by linear roller bearings extending along a second axis in the plane of and perpendicular to said first axis for relative movement of said second and third members along said second axis, whereby said first member is movable along said first axis upon said second member and along said second axis with said second member for orbital movement of said first member with said bearing; and f) means for mounting said blade to said first member for direct transmission of said orbital motion from said first member to said blade.
