Abstract
A portable hand tool includes a frame for guiding a sheet of material, e.g., sheet metal. A pair of shafts are spaced from each other and are selectively slideable relative to the frame to define a plurality of adjustment positions. A pair of rollers are respectively mounted to the shafts for deforming the sheet of material between the rollers. An adjustment rod is mounted to and extends outwardly from the frame. A support interconnects the shafts and an adjustment device is rotatably engaged with the support. A coupling device is disposed about the adjustment rod and is moveable between an engaged position and a disengaged position. In the engaged position, the coupling device couples the adjustment rod and the adjustment device to lock the shafts and rollers laterally relative to the frame. In the disengaged position, the shafts and rollers are slideable relative to the frame between the adjustment positions.
