Description: |
| Wedge adjust nut wrench with a spring connecting the sliding wedge and main frame; corresponds to wrenches marked "SUL / Germany." Corresponding British patent GB-169,675. German patents could be issued to manufacturing firms rather than named individuals.
The basic design of these wedge-adjust wrenches likely evolved from J.R. Long patents -- 890,146 and others in that evolutionary chain. |
