July 21, 2006: Classifying tools as wrenches is arbitrary at the "fringes." The original intent of this portion of the HISTORIC PATENT IMAGES listings was to list the patent numbers of wrench patents including some pliers, tongs, ratchets, and tool patents that include auxiliary wrenches in the drawings or text. A few patents for wrench manufacturing processes and machinery were also going to be included.
The compiler has since redirected this effort to adding wrench patents to the DATAMP database.
The 8-digit number in parenthesis is the patent issue date in YYYYMMDD format.
