Abstract:
1. An apparatus for removing a fastener from a corresponding aperture defined by a workpiece, the apparatus comprising: a pulling plug for engaging a head of the fastener, a drive shaft operably connected to said pulling plug; and a sleeve member that is threadably engaged by said drive shaft and is capable of being urged into operable contact with a surface of the workpiece without positively engaging the workpiece, wherein said drive shaft is capable of being threadably retracted so as to move in a direction away from the workpiece while said sleeve member continues to be urged into operable contact with the surface of the workpiece without positively engaging the workpiece, thereby correspondingly moving said pulling plug away from the surface of the workpiece in to remove the fastener from the aperture defined by the workpiece, and wherein the operable connection of said drive shaft to said pulling plug is such that said drive shaft and said pulling plug rotate in unison so that the threadable retraction of said drive shaft also imparts both relative axial and rotational movement between said pulling plug and said sleeve member.
