Abstract

1432238 Cable strippers UTILITY TOOL CORP 3 April 1973 15815/73 Heading H2C A cutting member for severing covering material from electric cable has a chisel blade and an incising blade, the incising blade having at least one cutting edge disposed for cutting when the member is moved in the chiselling direction of the chisel blade, the cutting edge of the chisel blade and the one cutting edge of the incising blade lying in respective mutuallyperpendicular planes each parallel to the chiselling direction, the one cutting edge of the incising blade being inclined to the chiselling direction, the member having a stop at a point on, or at the end of, the one cutting edge of the incising blade and spaced from the cutting edge of the chisel blade. For removing the sheath and screen from a cable, Fig. 1, a member 10 has a chisel blade 16 and an incising blade 18 so disposed that when the member 10 traces a helical path relative to the cable the chisel blade makes a cylindrical cut and the incising blade 18 a radially-extending helical cut. When the member 10 is redirected into a circular path the cut material is severed to leave a square shoulder at 40 and a reduced cylindrical end portion 28, Fig. 5. The cutting line of the incising blade 18, Fig. 3, is stopped at 38 where the edge 34 intersects the bevelled surface (22, Fig. 1) of the chisel blade 16 a little way behind the chisel edge 20; this arrangement allows the bevel 22 to flare the cut end at F, Fig. 5, to facilitate the insertion of a sleeve. A modification, 110, Figs. 6 and 7, has a chisel blade 116, and an incising blade 118 stopped at 138 by a further blade having an edge 144, the convergence of the edges 134 and 144 enabling soft materials to be cut with less risk of tearing. A further embodiment 210, Fig. 13, suitable for severing the primary insulation from coaxial cable, has a chisel blade 216, and an incising blade 218 comprising two edges 234, 234<SP>1</SP>, a stop being provided at 238 where the edge 234 intersects the periphery of a roller 252. The arrangement is such that the cut end is square. Adjustment of the depth of cut is provided by rotating an element 246 carrying the roller 252 about a pivot 248 in a main element 214 having the blade portions 216, 218.
