Abstract
One embodiment of a fastener holding driver 1-100 having a shank 1-126 with a shank tip 1-128, sleeve 1-102, assembly spring 1-142, jaw carriage 1-114 and jaws 1-124 which uses tightening threads 1-152 to tension a fastener onto the shank tip 1-128 with only one operation. When the driver 1-100 installs the fastener into a workpiece the sleeve 1-102 causes the jaws 1-124 to be open so that the fastener can be driven fully into the workpiece with the driver 1-100 returning to it's original driver state ready for the next fastener. Other embodiments are described and shown.
Claims20
A fastener holding driver comprising:
- a) a shank with a shank tip for engaging a fastener,
- b) a jaw assembly movably mounted on said shank, said jaw assembly comprising:
- i) a jaw carriage, and
- ii) a plurality of jaws, and
- iii) a sleeve on said jaw carriage,
- c) a plurality of tightening threads located on the elements of said fastener holding driver,
- wherein a user may manipulate one or more elements of said fastener holding driver causing said plurality of tightening threads to cause said plurality of jaws to rigidly hold said fastener onto said shank tip with positive force,
- further wherein installation of said fastener into a workpiece by said fastener holding driver causes said sleeve to cause said plurality of jaws to no longer hold said fastener onto said shank tip,
- further wherein installation of said fastener into said workpiece by said fastener holding driver causes said plurality of tightening threads to be returned into their original thread position ready for the next fastener to be installed.

A fastener holding driver comprising:
- a) a shank with a shank tip for engaging a fastener,
- b) a jaw assembly movably mounted on said shank, said jaw assembly comprising:
- i) a jaw carriage, and
- ii) a plurality of jaws, and
- iii) a sleeve on said jaw carriage,
- c) a releasable helical mechanical advantage means,
- wherein a user may manipulate one or more elements of said fastener holding driver causing said releasable helical mechanical advantage means to cause said plurality of jaws to rigidly hold said fastener onto said shank tip with positive force,
- further wherein installation of said fastener into a workpiece by said fastener holding driver causes said sleeve to cause said plurality of jaws to no longer hold said fastener onto said shank tip,
- further wherein said user may manipulate as few as one element of said fastener holding driver to both lock said plurality of jaws and also to rigidly hold said fastener onto said shank tip with said positive force.
6 more elements
A fastener holding driver comprising:
- a) a shank with a shank tip for engaging a fastener,
- b) a jaw assembly movably mounted on said shank, said jaw assembly comprising:
- i) a jaw carriage, and
- ii) a plurality of jaws, and
- iii) a sleeve on said jaw carriage,
- c) a plurality of tightening threads located on the elements of said fastener holding driver,
- d) a means to hold said jaw assembly in one or more positions on said shank,
- wherein a user may manipulate one or more elements of said fastener holding driver causing said plurality of tightening threads to cause said plurality of jaws to rigidly tension said fastener onto said shank tip by the full force generated by said user manipulating said plurality of tightening threads,
- further wherein installation of said fastener into a workpiece by said fastener holding driver causes said sleeve to cause said plurality of jaws to no longer hold said fastener onto said shank tip.
6 more elements
