The Safety Chuck was invented for the textile industry in 1948 by Boschert GmbH in Germany. The inventor called it a "folding bearing" or klapplager. The British were the next to see it. They observed that the locking collar or handwheel closed automatically if the roll rotated. It starts to close from 5 degrees either side of 0 degrees and is closed at 15 degrees either side of 0 degrees. They considered this a safety feature, so they called it a "Safety Chuck". Although it is a coupling and not a true chuck, the name Safety Chuck stuck. Boschert GmbH is the world's largest manufacturer of Safety Chucks and is considered as the standard of the industry.
