Iron Chink
The ‘Iron Chink‘, however, is a machine/device used for scaling, cutting, dressing and canning fish, especially salmon fish, automatically, needing very few workers. This machine was invented and patented by Edmund A. Smith in 1905, and as the Chinese fish plant workers were held in great respect for their workmanship in those days, he named his machine ‘Iron Chink’.
