ABSTRACT:
An apparatus is provided for selectively shearing angle iron and flat stock. The apparatus has a frame defining a receiving station for separately receiving angle iron or flat stock. The receiving station includes a stationary shear blade assembly having two shearing edges extending from a vertex to define a generally 90.degree. angle inside corner. A first arm is pivotally mounted to the frame about a first pivot axis. A second arm is pivotally mounted to the first arm for pivoting movement about a second pivot axis. The second arm includes a movable shear blade assembly having two shearing edges directed outwardly to define a generally 90.degree. angle outside corner. An actuator is mounted on the frame for pivoting the first arm about the first pivot axis between open and closed positions. The second arm defines a guide way, and the frame has a guide member which is selectively positionable relative to the first axis for slidably engaging the guide way to pivot the second arm about the second pivot axis.
