CA-254158 in Canadian Patents Database
Description:
Canadian patent corresponding to U.S. patent 1,659,081. The primary features emphasized in the patent are the gripping jaw component with recessed center section, and the threaded connector end for the chain which allows for adjusting the grip. The Cantiliver Pipe Wrench was written up and advertised in oil and gas trade journals.

The Canadian Patents Database does not include the cover sheet that would provide the applicants' addresses. The drawing has a patent attorney's New York City location.

As in the parallel U.S. patent, the specifications describe the patent as improvement on a design which was the subject of an earlier application.
