Description: |
The patent improves the chain wrench based on patent nos. 876,927 and 952,860. The link connecting the chain to the handle is strengthened. The jaw plates are more widely spaced, and extensions of the handle form the "floor" of the chain holding space. Amborn patented a second modification in a parallel patent (no. 1,146,120).
