Description: |
| The patent is for an "S" shaped double-ended alligator wrench with thread cleaning dies in an enlarged portion of the center of the shank. Corresponding Canadian patent CA-86524 was granted April 12, 1904 with Marshall Oil Company also listed as patentee. The wrench was produced without the separate plate containing die sockets described in the specifications and shown in the drawing. British patent GB-190406259 (No. 6259 of 1904) conforms to the wrench as produced.
An uncommon variant has three sizes of pipe dies rather than the bolt dies shown in the advertising. The "CROCODILE" variant has one tip extended to form a screwdriver.
The double alligator wrench with threading dies produced on the basis of patent no. 816,570 is nearly identical in appearance to the HAWKEYE wrenches.
The earliest wrench patent incorporating threading dies was George Meader's January 17, 1865 adjustable wrench (Pat. no. 45,931). |
