ABSTRACT:
Handle-operated shear-type cable cutter with one jaw member integral with one of its handles, the other jaw member being connected with the first by a main pivot about which said other jaw member rotates. An arcuate ratchet segment, integral with the rotatable jaw member, has ratchet teeth on a portion of its periphery remote from the cutting edge of the jaw. It is driven by a pawl assembly comprising a U-shaped bracket, the saddle of which houses a drive pawl and the legs of which carry, at their free ends, journals which support the main pivot pin and transmit thrust to the jaw members. A link member, pivoted at both ends, interconnects the operating handle with the pawl assembly. The cutting edges of the jaws are shaped to define an opening within the tips as the jaws meet, which is preferably diamond-shaped, but which reduces in size as the jaws close. A lost-motion pin-in-slot connection limits closing movement of the handles.
