Abstract
Abstract A tool for stripping the insulation from electrical cables and the like. An elongated handle has a generally circular cablereceiving zone on one end with a rigid frame overlying and defining part of the cable-receiving zone. The handle and frame are spring-biased toward each other along the axis of the handle for firmly holding a cable in the cable-receiving zone. A cutting edge is adjustably mounted in the cable-receiving zone at an angle to its pivotal axis about which it is free to rotate.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
108 words
In a tool for stripping the insulation from cable and the like, an elongated handle with a generally circular cablereceiving zone on one end thereof, a frame overlying and defining a part of the cable-receiving zone with the handle and frame being spring-biased toward each other so that a cable in the cable-receiving zone will be firmly held against the end of the handle, and a cutting edge adjustably mounted in the cablereceiving zone with the cutting edge being free to rotate about a pivotal axis extending longitudinally through the handle and said cutting edge being along a line disposed at an angle that intersects the pivotal axis.
Claim 2
Dependent Claim
108 words
In a tool for stripping the insulation from cable and the like, an elongated handle with a generally circular cablereceiving zone on one end thereof, a frame overlying and defining a part of the cable-receiving zone with the handle and frame being spring-biased toward each other so that a cable in the cable-receiving zone will be firmly held against the end of the handle, and a cutting edge adjustably mounted in the cablereceiving zone with the cutting edge being free to rotate about a pivotal axis extending longitudinally through the handle and said cutting edge being along a line disposed at an angle that intersects the pivotal axis.
Claim 3
Dependent Claim
88 words
The structure of claim 1 further characterized in that the cutting edge is formed along the free end portion of a cutting blade, with the blade being rotatably mounted along said pivotal axis, and with the free end portion being laterally offset from said pivotal axis which the cutting edge faces, so that the cutting edge may swivel about the pivotal axis and automatically align itself in the direction of motion of the tool for both circular cuts around the cable and axial cuts longitudinally along the cable.
Claim 4
Dependent Claim
20 words
The structure of claim 2 further characterized in that the pivotal axis is parallel to the axis of the handle.
Claim 5
Dependent Claim
35 words
The structure of claim 1 further characterized in that the generally circular cable-receiving zone on one end of the handle is defined and positioned such that its center is laterally offset from the pivotal axis.
Claim 6
Dependent Claim
38 words
The structure of claim 2 further characterized in that the blade is mounted on the handle and projects therefrom beyond the said one end so that its cutting edge is disposed at least partially within the cable-receiving zone.
Claim 7
Dependent Claim
52 words
The structure of claim 2 further characterized in that the blade is adjustably mounted along said pivotal axis such that it can be fixed in a number of positions so that the cutting edge will project into the cable-receiving zone by varying amounts depending on the size of the cable being stripped.
Claim 8
Dependent Claim
48 words
The structure of claim 1 further characterized in that the cutting edge is disposed at an acute angle to the pivotal axis so that as the handle is rotated about a cable there will be a component of force tending to bias the cutting edge toward the cable.
