Description: |
| Self-adjusting nut wrench that appears to be a simplification of DE-51700; DINGLER'S POLYTECHNISCHES JOURNAL (March 20, 1891) describes a self-adjusting wrench based on this patent with opening range of 25 - 50 mm. An 1892 issue of POLYTECHNICHES NOTIZBLATT includes an article that mentions a second size with opening range of 6 - 32 mm and notes the wrench was marketed as "Schilling's Patentschraubenschlüssel."
