Jacobs Chuck

It’s hard to believe that a set of bruised knuckles was the impetus for one of the most significant industrial advancements in the 20th Century.

Arthur Irving Jacobs was never one for leaving things alone. He was always improving them - continually coming up with new ways of working and new gadgets to do the work. Before he was 30, "A.I.", as he was known, had perfected a new method for making bicycle spokes, and chains, plus many other manufacturing advancements.
