Abstract

According to typical inventive practice, a cable is grasped by a Kellum grip and is positioned through the topside “V”-notch of an “M”-structure. Two wires engage pulleys and a ratchet distanced from the pulleys. The pulleys are joined with a grip plate, attached at an axial end of the Kellum grip. The ratchet is joined with a ratchet plate, proximate and/or attached to the “M”-structure. The “M”-structure has joined therewith three blade wheels having cutting orientations in the same linear direction. The blade wheels are situated interiorly and perpendicularly in correspondence to the geometric sides of the inverted triangle defined by the “V”-notch. Each blade wheel is adjustable to suit the diameter of the cable positioned through the “V”-notch. Ratcheting of the wires moves the ratchet plate and hence the “M”-structure, resulting in creation via the blade wheels of three parallel slices in the cable along its axis.

First claim

What is claimed is:

1. A cutting tool comprising:
a blade support having an inverted triangular opening, the inverted triangular opening describing a geometric isosceles triangle characterized by a vertical bisector, two isosceles sides forming an upward interior angle of approximately sixty degrees, and a horizontal geometric side opposite the upward interior angle;
three blade wheels for rotatably effecting three respective longitudinal cuts in a cable characterized by a length, a first said blade wheel associated with a first said isosceles side, a second said blade wheel associated with a second said isosceles side, a third said blade wheel associated with the horizontal geometric side, the first said blade wheel being adjustable in a direction along the first said isosceles side and being further adjustable in a direction perpendicular to the first said isosceles side, the second said blade wheel being adjustable in a direction along the second said isosceles side and being further adjustable in a direction perpendicular to the second said isosceles side, the third said blade wheel being adjustable in a direction along the vertical bisector.

2. The cutting tool of claim 1 wherein, based on the respective said adjustabilities of said three blade wheels, said three blade wheels are positionable for rotatably effecting said three respective longitudinal cuts in said cable during relative movement of said blade support and said cable passing through said inverted triangular opening.

3. The cutting tool of claim 2 wherein said cable is characterized by a circumference, and wherein said three blade wheels are positionable for rotatably effecting said three longitudinal cuts separated approximately one hundred twenty degrees apart around said circumference of said cable, the first said blade wheel for effecting the first said longitudinal cut, the second said blade wheel for effecting the second said longitudinal cut, and the third said blade wheel for effecting the third said longitudinal cut.

4. The cutting tool of claim 3 wherein said three blade wheels are positioned relative to one another such that they are capable of making said three longitudinal cuts having approximately the same cut length.

5. A cable incision device comprising:
a generally M-shaped member having an isosceles triangular notch through which a cable may pass, said isosceles triangular notch characterized by a vertical geometric bisector, a first angled edge, and a second angled edge, said first angled edge and said second angled edge edges meeting at a geometric apex of said isosceles triangular notch;
a horizontal cross-member attached to the generally M-shaped member so as to traverse said isosceles triangular notch, said horizontal cross-member extending perpendicular to the vertical geometric bisector and positionally adjustable along the vertical geometric bisector;
a first blade associated with and perpendicular to said first angled edge, said first blade being positionally adjustable in directions along and perpendicular to said first angled edge;
a second blade associated with and perpendicular to said second angled edge, said second blade being positionally adjustable in directions along and perpendicular to said second angled edge;
a third blade associated with the bar said horizontal cross-member and coincident with the vertical geometric bisector, said third blade being positionally adjustable in a direction along the vertical geometric bisector in accordance with the positional adjustability of said horizontal cross-member along the vertical geometric bisector.

6. The cable incision device of claim 5 wherein:
said cable has a longitudinal axis;
said first blade, said second blade, and said third blade are positionable for effectuating three parallel incisions in said cable along the longitudinal axis of said cable during relative motion of said cable through said isosceles triangular notch with respect to said first blade, said second blade, and said third blade;
said first blade for making a first one of said incisions;
said second blade for making a one of second said incisions; and
said third blade for making a third one of said incisions.

7. The cable incision device of claim 6 wherein each of said first blade, said second blade, and said third blade is a wheel blade rotatable for making the corresponding said incision along the longitudinal axis of said cable.

8. The cable incision device of claim 7 wherein said three blades are positioned relative to one another such that they are capable of making said three parallel incisions approximately equal in length.

9. An apparatus for incising a cable, the apparatus comprising:
a vertical V-notched plate, said vertical V-notched plate having an upwardly open V-notch;
a horizontal bar, said horizontal bar attached to said vertical V-notched plate and extending across said upwardly open V-notch, said horizontal bar having a lower bar edge, wherein a combination of a portion of said upwardly open V-notch and a portion of said lower bar edge geometrically describing describes an inverted isosceles triangle lying in a vertical geometric plane, said inverted isosceles triangle having two equal triangular sides and a horizontal triangular base above said two equal triangular sides, said two equal triangular sides corresponding to said portion of said upwardly open V-notch, said horizontal triangular base corresponding to said portion of said lower bar edge, wherein said inverted isosceles triangle is characterized by a vertical bisector between said two equal triangular sides;
three wheel blades, said three wheel blades spaced apart so as to respectively correspond to said two equal triangular sides and said horizontal triangular base of said inverted isosceles triangle, each said wheel blade being rotatable perpendicular to said geometric plane, said three wheel blades including:
a vertical said wheel blade, the vertical said wheel blade coupled with said horizontal bar, said horizontal bar and hence the vertical said wheel blade being adjustable in a direction along said vertical bisector of said V-notch inverted isosceles triangle;
a first oblique said wheel blade, the first oblique said wheel blade being adjustable both in a direction along and a direction perpendicular to a first said equal triangular side of said inverted isosceles triangle;
a second oblique said wheel blade, the second oblique said wheel blade being adjustable both in a direction along and a direction perpendicular to a second said equal triangular side of said inverted isosceles triangle;

wherein, in association with motion of said three wheel blades relative to a cable when the cable is positioned through said V-notch inverted isosceles triangle and contacts said three wheel blades, said three wheel blades can incise said cable to form three parallel cable-lengthwise cuts in said cable.

10. The apparatus for incising of claim 9 wherein said three wheel blades are positioned relative to one another such that they are capable of making said three parallel cable-lengthwise cuts in said cable about equal in cut length.
