Description: |
| The patent focuses on the gripping chain, the rack teeth on the end of that chain and corresponding gear teeth on the handle, and the helical spring behind the gear teeth on the handle. The objects of the construction are to accomplish the firmest grip possible on a well casing, without crushing said casing, and to have easily replaceable parts.
The "safety chain" in the patent is the subject of patent 1,587,892, and the basic tongs structure is from patent no. 1,447,920.
In the absence of proof, it is uncertain whether the details of this patent were incorporated in "improved BESSOLO ROTARY TONGS" produced by Bethlehem Shipbuilding in the early - mid 1920s. |
