Description: |
| The patent claims a principle of "plates" to adjust the size of a wrench jaw opening. The plates could pivot or slide from a recess in the wrench, with or without the use of a clamping screw to hold them in position. The patent received an extensive write-up in the May 24, 1872 "English Mechanic and World of Science." (pg 243 ff.)

The patent # used in DATAMP represents the year of issue and the patent # (with "leading zeros" to make the number total nine digits). This patent is #2,182 of the year 1871. |
