Abstract
The present invention relates to an improved torquing apparatus that may be retrofitted in an in-line relationship, onto an existent power wrench as normally employed in mass production assembly processes. The disclosed apparatus is adapted to fit between the head of the wrench motor and the wrench attachment,so that the original torquing speed and power are transmitted to the work-piece in the same manner as originally intended. The disclosed torquing apparatus is designed to practically immune extraneous forces; so that the disclosed apparatus is particularly well adapted for wrenches employed in hand-held applications.
