A cable cutting device having one handle of the cutter placed parallel and closely adjacent to the cable which is to undergo cutting. When a cable is about to be cut, the cable and the handle of the cutter are placed in a side by side relationship and both the cable and handle of the cutter are grasped by the user. The remaining handle is attached to a ratchet mechanism in the cutter and is oscillated to drive the cutter by means of a ratchet device to cut the cable which is still being grasped by the user. Now, the severed cable may be suitably disposed of in a controlled and safe manner. If the user is a utility lineman, the safety associated with the above operation cannot be overemphasized.
A ratchet cable cutter comprising, in combination, a housing having a stationary handle and a stationary blade mounted thereon, a ratchet blade rotatably mounted on pivot means in said housing for rotation about a pivot axis, a driving handle rotatably mounted on said housing, whereby said driving handle can swing back and forth toward and away from said stationary handle during a cutting operation, at least one ratchet drive lever rotatably mounted in said housing, whereby said ratchet drive lever swings back and forth in a small arc within said housing, a pawl rotatably mounted on said ratchet drive lever so as to engage said ratchet blade to rotate said ratchet blade forward, a detent rotatably mounted in said housing so as to engage said ratchet blade to prevent backward rotation of said ratchet blade, and connecting means for connecting said driving handle to said ratchet drive lever to cause said ratchet drive lever to move in concert with said driving handle,
A ratchet cable cutter comprising, in combination, a stationary frame assembly having a stationary blade and a stationary handle assembly, a ratchet blade rotatably supported about a pivot axis in said frame assembly, a driving handle assembly rotatably supported upon said frame assembly, a drive lever rotatably supported upon said frame assembly, a pawl rotatably supported upon said drive lever in cooperative relationship with said ratchet blade to drive said ratchet blade forward, a detent rotatably supported upon said frame assembly in cooperative relationship with said ratchet blade to restrain backward movement of said ratchet blade, and a motion transfer mechanism mounted between said driving handle assembly and said drive lever, wherein said handle assemblies are mounted on said frame assembly in a plane parallel to said pivot axis.
A ratchet cutter comprising a housing for mounting a stationary blade and a stationary handle thereon, a ratchet blade rotatably supported in said housing and a driving handle assembly rotatably supported on said housing to ratchet said ratchet blade toward said stationary blade, wherein said stationary handle and said driving handle assembly are located in a plane parallel to the pivot axis of said rotatable ratchet blade.
