Abstract
A tool manipulating device includes a combination of depth setting, length adjusting and workpiece clamp members provided on a longitudinal hand-held handle. The depth setting member has a blade assembly that extends perpendicular to the hand-held handle. The blade assembly is capable of rotating onto itself after penetrating into a workpiece to be stripped from its jacket at a predetermined depth to produce a ring cut and an axial cut of the workpiece upon sequentially rotating and axially pulling the cable relative to the handle.
Claims34
A device for manipulating a workpiece selected from the group consisting of wires and cables, said device comprising:
- a handle having a longitudinal axis defining a seat receiving a workpiece;
- a guide opening toward the seat and mounted on the handle to extend therefrom along a guide axis transverse to the longitudinal axis;
- a blade received in the guide to rotate therewith about the longitudinal axis, the blade spinning freely about the guide axis and controllably projecting from the guide into the seat at a predetermined depth;
- a clamp for engaging the workpiece, the clamp being pivotally mounted on the handle to swing between an open position and a closed position about a clamp axis extending perpendicular to the longitudinal and guide axes, wherein the clamp presses the workpiece in the seat against the blade to enable it to penetrate the workpiece at the predetermined depth, the clamp being sized to enable the workpiece and the handle to rotate and to axially move relative each other upon applying radial and axial external thrusts respectively.

- a clamp for engaging the workpiece pivotally mounted on the handle to swing between an open position and a closed position, the clamp being sized to enable the workpiece and the handle to rotate and to axially move relative each other upon applying radial and axial external thrusts respectively, the clamp having
- inner and outer ends, the outer end being swung away from the handle in the opening position of the clamp to form a passage receiving the workpiece and urging against the handle in the closed position of the clamp,
- a pair of spaced apart longitudinal arms extending between the inner and outer ends, and
- a pair of spaced apart compression springs braced against the inner end of the clamp and the handle to resiliently urge clamp to its closed position.

A device for manipulating a workpiece selected from the group consisting of wires and cables, said device comprising:
- a handle having a longitudinal axis and defining a workpiece seat;
- a blade having a blade axis transverse to the longitudinal axis, the blade controllably projecting into the seat at a predetermined depth;
- a clamp mounted on the handle and engageable with the workpiece in the seat for pressing the workpiece against the blade to enable it to penetrate the workpiece at a predetermined depth;
- a stop mounted displaceably in the handle and shaped to abut the workpiece to reciprocally move therewith along the longitudinal axis between an inner position relatively close to said blade and an outer position relatively remote from blade;
- and
- a locking element removably mounted on the handle and displaceable perpendicular to the longitudinal axis towards an arresting position, wherein said the locking element urges against the stop at any of a plurality of axial positions in and between its inner and outer positions, so as to set a predetermined length of the workpiece to be stripped.

A device for manipulating a workpiece selected from the group consisting of wires and cables, said device comprising:
- a handle defining a seat for receiving a workpiece and extending along a longitudinal axis;
- a guide opening toward the seat and mounted on the handle to extend therefrom along a guide axis transverse to the longitudinal axis;
- a blade mounted rotatably in the guide to freely spin about the guide axis and having a substantially flat cutting edge lying generally in a plane that extends radially of the guide axis;
- a depth setting member mounted on the handle and controllably actuatable to set a predetermined distance at which the cutting edge penetrates into the workpiece, the depth setting member being connected to and displacing the blade along the guide axis at the predetermined distance;
- and
- a clamp for pressing the workpiece in the seat against the flat cutting edge to enable the flat cutting edge to penetrate into the workpiece at the predetermined distance, the flat cutting edge extending substantially perpendicular to the longitudinal axis to circumferentially cut the workpiece when the handle and the workpiece rotate relative each other, the flat cutting edge spinning about the guide axis to extend parallel to the longitudinal axis to slice the workpiece parallel to the longitudinal axis upon pulling the workpiece and handle apart along the longitudinal axis.
