Description: |
| Major elements of the set are the ratchets that insert in slots in the ends of the heavy shank sections, the shanks with end and mid-line openings, the smaller extensions, universal joints, and the sockets. The parts can be assembled in various arrangements and are extensively interchangeable.
A socket and ratchet set produced by the Boston Auto Tool Company of Cambrigde, Mass. matches this patent in features and appearance, although none of the parts of the set have any patent markings. |
