Abstract

See full text

A customized, substantially standard power wrench is disclosed which has been modified to provide bolt holding capability. The housing is machined to provide a cylindrical opening and an internal, shallow, oval-shaped recess. An adapter assembly includes an adapter ring projecting through the housing opening formed with an oval-shaped flange axially positioning the adapter ring and preventing relative rotation between the adapter ring and the main housing of the wrench. A bit rod extends longitudinally through the wrench to the drive end and is biased toward the drive end by a spring located in a spring housing threaded onto the adapter ring. The simple mounting of the bit rod and adapter ring minimizes the conversion cost of the tool to render it capable of bolt holding operation.
