Before Arthur Irving was 30, "A.I.", as he was known, had perfected a new method for making bicycle spokes, and chains, plus many other manufacturing advancements. On one particular occasion, he was working with an old style drill press, trying to hold the belt control with one hand, and applying the spanner wrench to the other. The wrench slipped and he badly battered his knuckles. A.I. knew there had to be a better way. In a matter of days, he had developed the first drill chuck with a toothed sleeve and key. A few months later, he founded what would become The Jacobs Chuck Manufacturing Company. The keyed chuck helped to transform the production process just at the time when industrial manufacturing was about to experience its most significant growth in modern times. Today, the concept of the original keyed chuck is an integral part of all drill chuck technology. It has been applied to a wide range of applications, from the most sophisticated CNC machining to drilling with the smallest cordless portable drill. 

The Jacobs Chuck Manufacturing Company now operates as a division of APEX Tool Group.
