A power driver may include a housing, a tool chuck and a power take off mechanism. The tool chuck may have an input shaft mounted for rotation on the housing. The input shaft may support jaws. A chuck actuating shaft may be mounted for rotation on the input shaft. The power take off mechanism may be connected to the tool chuck. The power take off mechanism may be adjustable into a DRILL DRIVE MODE to rotationally drive the input shaft and the chuck actuating shaft together as a unit, and a CHUCK MODE to rotationally drive the chuck actuating shaft relative to the input shaft. The power take off mechanism may include a shift ring that is movable axially to achieve the various operational modes. During such axial movement, the shift ring may be rotationally locked to the housing and/or transmission components via compliant grounding mechanisms.

What is claimed is: 1. A power driver comprising: a housing; a lock member mounted for axial movement on the housing, the lock member being rotationally fixed to the housing; a tool chuck mounted for rotation on the housing, the tool chuck supporting jaws; a shift member for axial movement relative
What is claimed is: 1. A power driver comprising: a housing; a lock member mounted for axial movement on the housing, the lock member being rotationally fixed to the housing; a tool chuck mounted for rotation on the housing, the tool chuck supporting jaws; a shift member for axial movement relative to the housing and the tool chuck between a first position in which the shift member is rotatable relative to the lock member to achieve a DRILL/DRIVE MODE to rotationally drive the jaws, and a second position in which the shift member rotationally locks with the lock member if the shift member is meshed with the lock member to achieve a CHUCK MODE to open or close the jaws; wherein the lock member is axially displaced by the shift member when the shift member is moved to the second position and the shift member is not meshed with the lock member. 2. The power driver as set forth in claim 1, comprising: a spring captured between the lock member and the housing to influence the lock member toward the shift member. 3. The power driver as set forth in claim 1, wherein the lock member is ring shaped. 4. The power driver as set forth in claim 1, wherein the lock member has lugs facing the shift member, and wherein the shift member has lugs to engage with the lugs of the lock member. 5. The power driver as set forth in claim 1, wherein the lock member has axial extended legs that are slidably received by the housing. 6. The power driver as set forth in claim 1, wherein the lock member has radial extended tabs that are slidably received by the housing. 7. The power driver as set forth in claim 1, wherein the shift member is axially moveable to a third position in which the shift member is rotatable relative to the lock member to achieve a MANUAL OVERRIDE MODE to open or close the jaws. 8. The power driver as set forth in claim 1, comprising: a shift collar mounted for rotation on the housing to influence the shift member into the first and the second positions; wherein, when the shift member is in the second position, the lock member is axially displaceable by the shift collar to achieve a MANUAL OVERRIDE MODE to open or close the jaws. 9. The power drive as set forth in claim 1, wherein the jaws are threadless jaws. 10. A power driver comprising: a housing; a lock member mounted for axial movement on the housing, the lock member being rotationally fixed to the housing; a tool chuck having an input shaft, and a chuck actuating shaft mounted for rotation on the input shaft; and a power take off mechanism connected to the tool chuck, the power take off mechanism including a shift member for axial movement between a first position in which the shift member is rotatable relative to the lock member to achieve a DRILL/DRIVE MODE to rotationally drive the input shaft and the chuck actuating shaft together as a unit, and a second position in which the shift member rotationally locks with the lock member if the shift member is meshed with the lock member to achieve a CHUCK MODE to rotationally drive the chuck actuating shaft relative to the input shaft; wherein the lock member is axially displaced by the shift member when the shift member is moved to the second position and the shift member is not meshed with the lock member. 11. The power driver as set forth in claim 10, comprising: a spring captured between the lock member and the housing to influence the lock member toward the shift member. 12. The power driver as set forth in claim 10, wherein the lock member has lugs facing the shift member, and wherein the shift member has lugs to engage with the lugs of the lock member. 13. The power driver as set forth in claim 10, wherein the lock member has axial extended legs that are slidably received by the housing. 14. The power driver as set forth in claim 10, wherein the lock member has radial extended tabs that are slidably received by the housing. 15. The power driver as set forth in claim 10, wherein the shift member is axially moveable to a third position in which the shift member is rotatable relative to the lock member to achieve a MANUAL OVERRIDE MODE to rotationally drive the input shaft relative to the chuck actuating shaft. 16. The power driver as set forth in claim 10, comprising: a shift collar mounted for rotation on the housing to influence the shift member into the first and the second positions; wherein, when the shift member is in the second position, the lock member is axially displaceable by the shift collar to achieve a MANUAL OVERRIDE MODE to rotationally drive the input shaft relative to the chuck actuating shaft. 17. A power driver comprising: a housing; a lock member mounted for axial movement on the housing, the lock member being rotationally fixed to the housing; a transmission output; a tool chuck having an input shaft mounted for rotation on the housing and supporting jaws, and a chuck actuating shaft mounted for rotation on the input shaft; an output coupling rotationally fixed to the input shaft; a power take off drive disk rotationally fixed to the chuck actuating shaft; a shift member mounted for axial movement between a first position in which the shift member rotationally locks the output coupling to the transmission output, and a second position in which the shift member rotationally locks the output coupling to the lock member if the shift member is meshed with the lock member; wherein the lock member is axially displaced by the shift member when the shift member is moved to the second position and the shift member is not meshed with the lock member. 18. The power driver as set forth in claim 17, comprising: a drive member mounted for axial movement on the transmission output, the drive member being rotationally fixed to the transmission output; wherein the drive member is axially displaced by the shift member when the shift member is moved to the first position and the shift member is not meshed with the drive member. 19. The power driver as set forth in claim 18, comprising: a spring captured between the drive member and the housing to influence the drive member toward the shift member. 20. The power driver as set forth in claim 18, wherein the drive member has lugs facing the shift member, and wherein the shift member has lugs to engage with the lugs of the drive member.
