Abstract
Apparatus for straightening frames and sheet metal products including an upright post mounted on a base plate. A tubular member is adjustably mounted on the post for movement along the same. A fluid-actuated power device is secured to and extends laterally from the tubular member on the post, said power device including a piston rod extending outwardly from a fluid cylinder, the outer end of the piston rod being coupled to the adjacent ends of a pair of parallel bars which extend alongside the cylinder and in opposed directions away from the tubular member. A hook is secured to first ends of the bars and to first ends of a pair of braces so that, when the piston of the power device is moved away from the workpiece, a force will be exerted on the workpiece to tend to straighten it. During the time when the force is exerted on the workpiece, the apparatus is held down by a chain or other fastener to the floor on which the apparatus is mounted. A pair of braces are provided to provide a moment arm during application of the straightening force to the workpiece.
