Abstract:
A manually-operable wire stripper comprising:a body defining at its forward region a first wire-clamping jaw and at its rear a fixed handle; a second wire-clamping jaw pivoted about a first axis to the body and opposed to the first wire-clamping jaw for co-operation therewith to clamp a wire to be stripped, the first axis being displaced to one side of the center-line of the pair of clamping jaws; a pair of co-acting stripping jaws arranged between the clamping jaws for sliding movement with respect thereto along the length of a clamped wire, closing movement of the clamping jaws closing the stripping jaws; and an operating mechanism having: an operating lever pivoted about said first axis to the body and extending across the line of sliding movement of the stripping jaws to project from the body, juxtaposed to the fixed handle for gripping therewith; a draw-bar slidably mounted in the body and connected to the stripping jaws to effect said sliding movement thereof, the draw-bar defining a generally forwardly-facing first cam surface; an arm projecting from the second clamping jaw and having a second cam surface, and a roller located between the first and second cam surfaces and a rearwardly directed edge of the operating lever, the roller being driven by rearward pivoting movement of the lever; the arrangement of the operating mechanism being such that during initial movement of the operating lever the roller is driven against the first and second cam surfaces to effect closing movement of the second wire-clamping jaw until a wire to be stripped is clamped, whereafter continued movement of the operating lever drives the roller along the second cam surface thereby driving the draw-bar rearwardly through the first cam surface, to effect sliding stripping movement of the stripping jaws.
