Abstract
A device for transversely shearing a conduit including a first handle having a recessed conduit-receiving jaw at one end thereof, a shearing blade pivotally mounted on said first handle at the location for pivoting toward and away from said jaw, and including a plurality of ratchet teeth along one edge thereof, and a second handle pivotally connected to said jaw. An elongated toothed pawl bar having an elongated slot near one end thereof, and having pawl teeth at the other end thereof, is pivotally secured by a pivot pin extending through said slot to said second handle at a point spaced from its point of pivotal connection to said jaw. A cam stud secured to said first handle bears against one side edge of said pawl bar opposite the edge upon which the pawl teeth are located, and functions, when the handles are pivoted toward each other, to cam said pawl bar to a location at which said pawl teeth engage said ratchet teeth.
