Abstract:
1. An arbor device having a first end adapted to be combined with a power driver and a second end having a receiving bore that is adapted to receive a tool having at least one engagement surface, the device comprising: a drive key pivotally combined with the arbor, the drive key having a first position and a second position, wherein the drive key has a first face and a second face, and wherein the second face is at an angle with respect to the engagement surface of the tool when the drive key is in the first position and the second face is engaged with the engaging surface when the tool is in the second position; an outer sleeve combined with the arbor second end, the outer sleeve having a threaded inner surface; a threaded member having a threaded outer surface in threaded engagement with the threaded inner surface of the outer sleeve and having a first face engageable with the first face of the drive key; wherein rotation of the outer sleeve in a first direction causes the threaded member to move in a first direction and rotation of the outer sleeve in a second direction causes the threaded member to move in a second direction; wherein the first face of the threaded member engages the first face of the drive key and moves the drive key into its second position to engage the engagement surface of the tool as the threaded member is moved in the second direction; wherein the receiving bore receives the tool axially beyond an operative location where the first face of the threaded member engages the first face of the drive key; and an anti-rotation key combined with the arbor second end and adapted to be received by the elongated opening in the threaded member to prevent the threaded member from rotating as the outer sleeve is rotated.
