Description: |
| The handle, stock and fixed jaw are made from a single piece of metal. The movable jaw slides in a slot, and is adjusted by a bolt which extends through the fixed jaw end of the wrench. A retaining piece is inserted in the same opening. Gates' Feb. 12, 1889 patent (no. 397,794) elaborates related manufacturing processes.
This design also received Canadian patent no. 28,873 granted April 12, 1888.
Often called the "GATES BULL" which is most likely a mis-reading of "GATES BOLT WRENCH." If anyone has seen a contemporary product ad for this wrench, please contact the steward (use the "Report data errors.." link). |
