Description: |
There is an offset bend in the shank so the "T" handle is in line with the sockets. The socket pair has opposite-facing teeth, with corresponding opposite-facing teeth on the pivoting frame member holding the connecting shank for the socket pair. A 1907 ad shows two sizes of square and two sizes of hex socket pairs.
Marketed as the "BOSS" or "IMPROVED BOSS" cylinder tooth wrench. A trade announcement in 1902 noted the Minneapolis Implement Co. had an exclusive five-year distribution contract for the wrench. |
