Description: |
| The movable jaw's adjustment is held by a spring-tensioned secondary toothed lever within the "hollow" handle. Reif's wrench appears to have evolved from this patent, a second he received in September 1908 (Pat. No. 899805), and further modifications reflected in 1930 patent no. 1,761,586. |
