Description: |
| Combined pocket wrench and screwdriver for bicyclists. The screwdriver is slid in and out of the case and clamped in place by the set screw. The adjusting nut for the movable wrench jaw is stabilized by pins that fit in a groove.
A known example was offered at auction in the fall of 2010.
Brooke's parallel patent (no. 486,759) has a different arrangement for the screwdriver. |
