Patent ID: 8201430

Claim:
A device for preparing a workpiece, the device comprising: a hydraulic cylinder, the hydraulic cylinder fluidly coupled to a controlled source of hydraulic fluid pressure, the hydraulic cylinder having a ram, the ram moving responsive to the hydraulic fluid pressure; a linear gear, a first end of the linear gear coupled to the ram; a pinion gear, teeth of the pinion gear meshed with teeth of the linear gear such that linear motion of the linear gear results in rotational motion of the pinion gear; a bending member coupled to the pinion gear, the bending member rotating responsive to the rotational motion of the pinion gear; a bending mandrel mounted on a face of the bending member at a center of rotation of the bending member; a force mandrel mounted on the face of the bending member; a means for actuating the hydraulic fluid pressure; a means for attaching the device for preparing the workpiece to a boom of a skid-steer loader; wherein the hydraulic cylinder, the linear gear and the pinion gear are mounted within a case and an outside surface of the case has the means for attaching the device for preparing the workpiece to the boom of the skid-steer loader.
