Apparatus for cutting a conduit or tubular element transversely to the longitudinal axis thereof which includes a base having a housing projecting vertically therefrom. The housing includes opposed, substantially parallel side plates separated by a vertical slot at their upper ends, and by a mechanism chamber at their lower ends. A blade element is pivotally supported between the parallel side plates, and carries a plurality of ratchet teeth along the lower peripheral edge, and a cutting edge disposed at the opposite side of the blade element from the ratchet teeth. Between the teeth and cutting edge, the knife element has an elongated, arcuate slot formed therethrough. An operating handle is pivotally connected to the housing at a side thereof spaced from the pivotal axis of the blade element. A pawl lever is pivotally connected to the operating handle and has a dog thereon positioned to ride over and operatively engage the ratchet teeth as the operating handle is pivoted. An elongated indexing link is pivotally connected at one end to the pawl lever and carries a stud at its other end which rides in the arcuate slot in the blade element. A conduit supporting jaw is mounted at the upper side of the housing, and defines an arcuate recess dimensioned to support a conduit to be cut by the apparatus.

Floor or bench mounted conduit cutting device

A clamping device comprising an elongated wedge body having a bifurcated end, and a second end opposite the bifurcated end. The wedge body is of substantially rectangular transverse cross-sectional configuration, and is relatively thick at the second end, tapering to a relatively thin dimension at the bifurcated end. The wedge body has first and second sides extending between its bifurcated and second ends. Each of these sides carries a plurality of longitudinally spaced, contiguous teeth or serrations over a major portion of its length. The bifurcation in one end of the wedge body defines a pair of spaced, substantially parallel legs, which legs have continuations of the teeth or serrations extended along one side thereof, and are relatively smooth on the opposite side thereof. In a useful combination, the clamping device retains an electrical conductor in place at the location where it enters a knock-out window in a synthetic resin electrical box. The clamping device is wedged between the conductor and the portion of the box which defines the window so that the serrations carried on opposite sides of the wedge body engage, respectively, the synthetic resin of the box and the insulating jacket of the conductor to firmly clamp the conductor in position.
