Description: |
| This invention "has for its principal object the provision of a slow-hitting hammer having such fine control of air delivery that a single light rap may be given the rivet set, thus better adapting the tool to use in airplane manufacturing plants where the light rap serves as a signal from the operator on the outside of an airplane fuselage to his or her helper inside who backs up the rivets which rivet will next be hammered, thus reducing to a minimum any likelihood of the relatively frail aluminum wall that is being riveted being dented, or even punctured, and requiring removal of a large panel as a result of the failure on the part of the helper to back up the proper rivet."This patent number was listed in a Skil Corporation catalog. |
