Abstract: A stabilizer pad for attachment to an arm of a piece of earthmoving equipment such as a backhoe. In one embodiment the pad has a solid geometric shape such as a cube or pyramid with at least three outer surfaces, any one of which can be arranged as a ground engaging surface. The pad or the arm has a cut-out section for permitting rotation of the pad relative to the arm to at least two different positions. In another embodiment the pad is pivotally secured to the arm. In one position the pad is positioned below the arm and in the other position the pad rotates about 180.degree. with the end of the arm forming a grouser and the other side of the pad functioning to limit the penetration of the arm into the ground.

Abstract: Stretch bending or dieing mechanism including a drawing die press having apparatus for tensioning and/or stretching a workpiece, typically in sheet form, at opposite ends of a lower horizontally oriented stationary die. Prior to or in timed relation with the movement of the movable die to form a workpiece having its opposite ends secured in clamp jaws of sheet clamp units of the tensioning and/or stretching apparatus, fluid pressure actuated motors which support the sheet clamp units are actuated to lower the units to stretch and wrap the workpiece partly about the lower die. Simultaneously the units are moved in a predetermined path away from the lower die to tension and/or stretch the workpiece, as desired, by link mechanism having links of different length spaced lengthwise of the path of movement of the movable die.
