ABSTRACT:
An improved leg shear for use in slaughterhouses includes a movable blade supported in opposed tracks throughout its travel, such movable blade having flat "stop" portions at opposite ends of its cutting edge which, at the end of the travel of the movable blade in its cutting direction, engages an adjustably fixed spacer plate carried in the frame to provide a positive stop for the movable blade, the shear including, in addition, a fixed blade supported by the frame of the shear and sloped with respect to the movable blade to provide a scissorlike shearing of the object to be cut.
