Abstract
Abstract A hand tool for slitting the sheath on flat, two to four conductor, plastic clad cables wherein one or more pointed knives project from the end of a handle into a chamber bounded, opposite the knife blades, by a sloping wall, one end of which defines an opening only slightly larger than the cable to be cut while the other end of the wall defines one end of an elongated opening throughout which the cable can be moved to assume a range of angles relative to the knives. A cable to be cut may be introduced into the chamber at an angle such that its surface does not touch the knives, and the tool can then be moved to an angle such that the knife points are driven into the cable and the sheath is cut, to facilitate separation and stripping of the conductors.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
192 words
A cable splitting tool (according to claim 2 wherein) comprising an elongated handle portion and a hollow head portion at one end of the handle portion, the head portion including spaced parallel internal side walls and an internal top having a rear edge, said walls defining a cutting chamber, at least one pointed slitting blade extending into said chamber from the direction of the handle portion, the top wall of the chamber being so disposed that its rear edge defines the upper limit of a lateral opening, said edge lying substantially in a plane which passes through the blade point and is perpendicular to the length of the handle, the angle of the top wall relative to said plane being such that no point on the top wall surface is spaced from the point of the splitting blade by less than the thickness of a cable to be slit, the tool including a plurality of blades and means for mounting said blades in a predetermined position in the handle portion, and the blade mounting means (is) being an elongated turret pivotally mounted in the handle and provided with blades at each end.
Claim 2
Dependent Claim
20 words
A cable splitting tool according to claim 1 wherein there are more blades on one end than on the other.
Claim 3
Dependent Claim
211 words
A cable splitting tool (according to claim 1 which includes) comprising an elongated handle portion and a hollow head portion at one end of the handle portion, the head portion including spaced parallel internal side walls and an internal top having a rear edge, said walls defining a cutting chamber, at least one pointed slitting blade extending into said chamber from the direction of the handle portion, the top wall of the chamber being so disposed that its rear edge defines the upper limit of a lateral opening, said edge lying substantially in a plane which passes through the blade point and is perpendicular to the length of the handle, the angle of the top wall relative to said plane being such that no point on the top wall surface is spaced from the point of the slitting blade by less than the thickness of a cable to be slit, the tool including a rotatable turret having a hub portion journaled in said side walls of the cutting chamber, the turret being provided with a plurality of sets of pointed slitting blades projecting radially from said hub portion and being movable selectively into cutting positions, means for locking the turret in different selected positions and means for releasing said locking means.
Claim 4
Dependent Claim
26 words
A cable splitting tool according to claim 3 wherein the turret is provided with four sets of slitting blades spaced at 90° intervals around the hub.
Claim 5
Dependent Claim
78 words
A cable splitting tool according to claim 3 or 4 wherein the head portion is provided with a plurality of lateral slots in a side wall equal to the number of sets of blades, the turret is provided with an axially movable key, the hub is provided with means engageable with the key, and the key is engageable selectively with each slot and with said last named means to lock a selected set of blades in cutting position.
Claim 6
Dependent Claim
33 words
A cable splitting tool according to claim 5 which includes axially movable means associated with the turret for moving the key to a release position and means biasing the key toward locking position.
