Description:
The central idea of the the patent is multiple pivot points for tongs, with each handle having similar jaws. The patent was realized as multiple pivot point pliers -- "Pease's Combination Pliers" -- in the 1880s. Pease received another patent for adjustable-pivot tools on January 10, 1882 (pat. no. 252,248). The current patent is also cited together with H.S. Pullman's Mar. 25, 1884 pat. (no. 295,885) on Billings & Spencer pliers marketed early in the 20th Century.
