Description: |
| The tool combines an adjustable open-end wrench and a crimper tool to damage bolt threads to prevent nuts from vibrating loose and falling off. A known example appears to be a "double end" adjustable wrench, with a thumb screw in a sliding collar to hold the adjusted size.
Markings on that known example include "CAMPBELL PATENT AUG 27, 78" and *illegible* MAKER / ?Portland St.? NEW YORK |
