ABSTRACT:
A cutter suitable for severing thick communications cable comprises a cutting lever member and a holding lever member pivoted to each other between their ends to provide, at one end thereof, a pair of opposed jaws. One of the jaws is in the form of a hook-shaped holding member having a concave nesting area for receiving the cable to be cut, and the other jaw is in the form of a cutting head having a cutting edge facing the nesting area and the cable. The cutting lever member has an integral handle at its other end, while a ratchetting lever member, with handle, is pivotally mounted on the other end of the holding lever member. The rim of the cutting head opposite from its cutting edge is toothed to form a gear segment which meshes with a drive sprocket wheel rotatably mounted on the pivot which mounts the ratchetting lever member. An automatically controlled pawl acts between the ratchetting lever member and the sprocket, and when engaged permits ratchetted advance of the cutting edge through the cable by angularly reciprocating motion of the ratchetting lever member within a predetermined range. Stop means lock the ratchetting lever member to the holding lever member when it is urged beyond its ratchetting angular range, to permit rapid opening of the jaws for receiving the cable and rapid closing of the jaws into contact with the cable preparatory to cutting. The hook-shaped holding member comprises a pair of spaced-apart plates for receiving and supporting the cutting head laterally during the cutting operation.
