Description: |
| The patent describes a wrench with rotating sockets at both ends. Wrenches of this type are known as rotating socket bone wrenches.
Some variants of the HANDEE wrench from Mansfield, OH have "Pat Appld," but the wrench was already marketed in late 1921. The STAR 8-in-1 wrench from Bellevue, OH has "cube" shaped heads rather than the reinforced edge openings and "rounded" head shown in this patent. |
