Bramah made their first lock in 1784 and the patent was awarded in 1787. The designer was Joseph Bramah.
Joseph Bramah was a leading inventor of the industrial revolution, patenting over 18 new ideas, including a new valve for the water closet (toilet), the hydraulic pump, a fountain pen, and a fire engine. Bramah also introduced a beer hand pump for use at the bar, to prevent fluid loss when barmen went downstairs to pour a new jug! Due to the quality of his manufacturing, his name became a by-word amongst British Engineers for engineering excellence and many of his inventions are on display in the Science Museum in London. You can find one of his original toilets still working in Osborne House, Queen Victoria's home on the Isle of Wight.
The Bramah lock was unique and advanced property and valuables protection enormously. Indeed it was 50 years ahead of any Chubb lock and 70 years ahead of Yale.
Original Bramah locks are most often found on the highest quality homes and furniture.
