Abstract

Claims (32)

1. A stripping tool for cutting an armored cable, the stripping tool comprising:

a cable receiving handle comprising first and second channel members defining a cable receiving channel, the cable receiving channel having a channel width defined by a distance between the first channel member and the second channel member; and

a saw assembly comprising:

a first saw handle pivotally mounted to the first channel member at a first pivot point;

a second saw handle pivotally mounted to the second channel member at a second pivot point;

a first saw blade retained in a fixed first blade position onto the first saw handle;

a second saw blade retained in a fixed second blade position onto the second saw handle; and

a drive mechanism coupled to the first and second saw blades for rotatably driving the first and second saw blades;

wherein:

the channel width is adjustable between a maximum width and one of a plurality of cutting positions by applying a squeezing force to the first and second channel members;

the first channel member and the second channel member are each slidably connected to each other by a pair of spring pins, each spring pin comprising a spring to bias the first channel member away from the second channel member to the maximum channel width; and

the first saw handle and the second saw handle are each slidably connected to the pair of spring pins to bias the first saw handle and the second saw handle beyond the first channel member and the second channel member until the first saw blade and the second saw blade are outside the cable receiving channel.

2. The stripping tool according to claim 1 , wherein the fixed first blade position is opposed to the fixed second blade position.

3. The stripping tool according to claim 1 , wherein the drive mechanism comprises a series of gears coupled to the first and second saw blades.

4. The stripping tool of claim 3 , wherein the series of gears is an even number of interconnected gears in a planar alignment, such that the first and second saw blades rotate in the opposite direction with respect to an axis of the cable receiving channel.

5. The stripping tool of claim 3 , wherein the series of gears comprises a gear having a mobile axis of rotation.

6. The stripping tool according to claim 1 , wherein the drive mechanism comprises a manually rotatable crank arm.

7. The stripping tool according to claim 1 , wherein:

each of the first and second pivot points is located at a first end of the cable receiving handle;

each of the fixed first and second blade positions is located at a second end of the cable receiving handle; and

each of the fixed first and second blade positions is stationary relative to the first and second saw handles, and mobile relative to the cable receiving handle.

8. A method for cutting the armored cable, the method comprising:

positioning the armored cable within the cable receiving handle of the stripping tool of claim 1 ;

applying the squeezing force comprising a first force to the first channel member and a second force opposing the first force to the second channel members, such that the channel width defined by the distance between the first channel member the second channel member is equal to a width of the armored cable;

cutting an armor layer of the armored cable by rotating the first and second saw blade at a cutting depth within the cable receiving channel;

releasing the squeezing force; and

removing the armored cable from the cable receiving channel.

9. The method of claim 8 , wherein applying the squeezing force to the first and second channel members comprises:

applying the first force to the first saw handle pivotally connected to the first channel member, thereby pivoting the first saw handle into a fixed contacting position relative to the first channel member and advancing the first saw blade into the cable receiving channel through a slot in the first channel member;

applying the second force to the second saw handle pivotally connected to the second channel member, thereby pivoting the second saw handle into a fixed contacting position relative to the second channel member and advancing the second saw blade into the cable receiving channel through a slot in the second channel member, the second force opposing the first force;

the combined first and second forces further advancing at least one of the first and second channel members toward the other of the first and second channel members.

10. The method of claim 8 , wherein the squeezing force restricts axial movement of the armored cable during a cutting step.
