 It was only in 1837 that Hancock finally patented both his masticator and spreader (UK patent 7,344).Although the Mackintosh style of coat has become generic (abbreviated as mac or mack), the company that Hancock and Mackintosh established lives on as two separate entities, Mackintosh and Hancock Vulcanised Articles.Both continue to make rubberised coats using the same techniques and procedures pioneered by the two inventors, with Hancock Vulcanised Articles alone continuing to use the original Victorian Mill for all fabric production.
