ABSTRACT OF THE DISCLOSURE The present invention is directed to a shearing machine comprising a frame member having a throat, first upper and lower blades, second upper and lower blades and a ram member for carrying the first and second upper blades. The first upper and lower blades are connected at right angles to the second upper and lower blades, respectively. The shearing edge of the first upper blade is originally so inclined as to ascend from its free end toward the intersecting point where the shearing edges of the first and second upper blades intersect or are connected with each other at the right angle. Also, the shearing edge of the second upper blade is originally so inclined as to descend from the intersecting point toward its free end. The ram member is pivotally connected to the frame member by means of a pivot means so as to be rotated or swung up and down thereon by a drive means. The pivot means is horizontally coupled to the frame member at a location spaced upwardly from the level of the first and second lower blades so that the shearing edge of the second upper blade may be inclined with its free end located higher than the intersecting point when the ram member is lowered. Also, the second upper and lower blades are so disposed as to be located outside of the vertical plane of the outer side of the frame member to protrude outwardly therefrom together with the ends of the first upper and lower blades connected to the intersecting point.
