Description:

The patent is an improvement to patent no. 800,850, relating to the connection between the movable jaw and internal rod that transmits force and movement from the internal compression spring and operating lever.

This patent and parallel patent (no. 868,126) relate to the Irland Pipe Wrench (pat. nos. 732,858, 739,316, 800,850).

A 1913 Page-Storms catalog shows the IRLAND pipe wrench with "Patent Applied For." Perhaps their version had some additional modifications.
