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.
Patents 28, 37, 93, 98, 150, 229 & 238:
This mechanism operates so that as the lid of the box is raised, the two winged side trays and the front panel automatically open out simultaneously; this action is then reversed as the lid is lowered.
Patents 6, 45, 54, 59, 61, 75, 78, 101, 117, 132, 151, 228:
These mechanisms enabled the box to cantilever out and open into six compartmented tiers.
- The front panel of the box drops forward.
- The top two compartments cantilever out at 90 degrees.
- Secondary lower spring-loaded compartments cantilever out, operated by a sliding push button. The top two compartments have now swung round to the 180 degree position.
- Concealed spring-loaded drawers are released from the front of the secondary compartments, operated by push buttons.
Other important Betjemann Patent designs included ‘The Tantalus’ spirit and perfume stands (believed to have been conceived by John Betjemann), the ‘Self-Closing Book Slide’, the ‘Partners Inkwell’, the ‘Lockable Decanter’, the ‘Extending Dressing Case’ and ‘Extending Dressing Table’, the ‘Double Winged Cabinet of Games’, the ‘En Garde’ lock, the ‘Triple Opening Travelling Bag’, the ‘Quadruple Opening Travelling Bag’, the ‘Lift Out Well Travelling Bag’, the ‘Reverse Opening Travelling Bag’, the ‘Equipoise Candlestick’ and many other inventive adaptations to box, cabinet and lock mechanisms.
