ABSTRACT:
An improved self-feeding cable stripper is provided which has a base, preferably divided into two parts clampable together about a cable opening extending up through the base. The stripper also includes a cylinder bearing external threads, the cylinder being secured to the top of the base and also having a central cable-receiving opening extending therethrough and aligned with the base opening. A fitting bearing internal threads is threadably secured over the cylinder, the threads being arranged such that when the fitting approximates the base, the threads disengage so that the fitting turns freely on the cylinder. A cutter is mounted in the fitting and extends into a central cable-receiving opening in the fitting, which opening is aligned with the cylinder opening. The cutter has an adjustable blade for cutting sheathing of a cable, clamped in the base and extending up through all of the openings, when the fitting is screwed down on the cylinder. The cable sheathing is cut in a spiral pattern until the threads disengage, whereupon the cutter cuts a square edge on the sheathing. In one embodiment the cylinder threads are vertically interrupted to define a space for passage of waste cable sheathing particles without abrading the threads. For similar purposes a protector blade and washer may be secured to the fitting and overlie the cylinder. The lower end of the cylinder may also be notched to provide a cleaning area for removal of cable sheathing debris.
