Drill Chuck
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.
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
rest, as they say, is history.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.
