Description: |
| Self-adjusting wrench, compare to Gaisser's Nov. 16, 1915 patent 1,160,160. The patent includes a "return" spring which tends to close the jaws, and an internal spring to compensate for "lost motion." Although marked with the earlier patent date, the L.G. AUTOMATIC wrench as produced appears to actually better correspond to this patent. |
