The patent appears to coincide with Canadian patent CA-2,923 in that it includes several alternate means of constructing adjustable pipe tongs which received separate U.S. patents (142,143, 144,253 and 145,929).

Note: Early British patents (pre 1916) were numbered by the year and started at patent #1 at the start of each year in January. The patent # used in DATAMP represents the year of registration and the patent # (with "leading zeros" interposed to make the number total nine digits). This patent is #3762 of the year 1873.
