Wrench Patentee: Silvanus Hussey - Brant NY Granted:1892-05-24

Improvement to Hussey's January 20,1891 patent (no. 444,937). Both sides have "hook" fixed jaws and toothed gripping pieces on the movable jaw. The NIAGARA WRENCH COMPANY was incorporated at Albion, NY in December, 1892 under the laws of West Virginia in relation to the Hussey patents. Martin Donnelly suggests the Hartford Hardware Company produced it, in his writeup for an example with the patent date the only visible marking. That wrench includes a combination screw / quick adjustment on the main shank and head features closer to the earlier Hussey patent (no. 444,937).

US Patent: 1,334,156

October 10, 2017 - 3:29pm
Wrench Patentees: John H. Lagreid - Seattle WA , Oscar Becklin - Seattle WA Granted:1920-03-16

The quick-adjust mechanism is a toggle with teeth, that engages an off-center rack on the shank. An unmarked 14 inch example matching this patent may represent an early attempt at manufacture; the parts look mass produced rather than hand made as would be the case for a prototype. The design has a provision for an adjustment lock which does not appear on the unmarked example. The BECKLIN pipe wrench based on this patent matches further elaborations and refinements for which Becklin received pat. no 1,656,343 on Jan. 17, 1928. Lagreid developed an alternate design with a sliding pawl to hold adjustment; it received patent no. 1,559,328 on Oct. 27, 1925.
