Betjemann Patent Mechanisms

From 1859, based at 36, 38 & 40 Pentonville Road, London, George Betjemann and his two sons, George William Betjemann and John Betjemann, started to take the art of cabinet and box making to new creative heights. Under the business name of George Betjemann & Sons, they began to patent their innovative designs and mechanisms, and specific to boxes, there were two particularly impressive types of patented design.
