Abstract

An angle shear for cutting profile steel has generally parallel and spaced front and rear frame plates fixed relative to each other, at least one fixed blade carried on the front plate, a working slide displaceable vertically between the frame plates, and individual guide rails extending at an acute angle of generally 45.degree. to the vertical and secured to one of the frame plates. An angle slide displaceable along the guides generally at 45.degree. to the vertical between the plates carries a movable blade displaceable past the fixed blade. Formations link the slides for joint synchronous movement between the plates. Both slides move in generally the same plane and have front and rear faces directly confronting and engaging the front and rear plates, respectively.
