Inventor Joseph Bramah Patented a New Safety Lock
Inventor Joseph Bramah Patented a New Safety Lock Joseph Bramah was born April 13, 1748, in à Stainborough Lane Farm, Stainborough,à Barnsleyà Yorkshire. He was an Englishà inventorà andà locksmith. He is best known for having invented theà hydraulic press. He is considered along with William George Armstrong, a father of hydraulic engineering. Early Years Bramahà was the second son in the family ofà four sons and two daughtersà of Joseph Bramma (different spelling), a farmer, and his wife, Mary Denton. He studied at the local school and after finishing school he completed a carpentry apprenticeship. He then moved toà London, where he began working as a cabinet-maker. In 1783 he married Mary Lawton and the couple established their home in London. They eventually had a daughter and four sons. Water Closet Inà London, Bramah worked installing water closets (toilets) which were designed by Alexander Cumming in 1775. He discovered, though, that model being installed in London houses had a tendency to freeze in cold weather. Although it was technically his boss who improved the design by replacing the usual slide valve with a hinged flap that sealed the bottom of the bowl, Bramah obtained the patent for it in 1778,à and began making toilets at a workshop. The design was produced well into the 19th century. Bramahs original water closets are still working inà Osbourne House,à Queen Victorias home on theà Isle of Wight. Bramah Safety Lock After attending some lectures on technical aspects ofà locks, Bramah patented the Bramahà safety lockà on August 21, 1784. His lock was considered unpickable until it was finally picked in 1851. This lock is now located in the Science Museum in London. According to lock expert Sandra Davis, In 1784, he patented his lock which for many years had the reputation of being absolutely unpickable. He offered à £200 to anyone who could pick his lock and although many tried it - it was not until 1851 that the money was won by an American, A.C. Hobbs, although it took him 16 days to do it! Joseph Bramah was deservedlyà honouredà and admired as one of the earliest mechanical geniuses of his day. The same year as he received his lock patent, heà set up the Bramah Lock Company. Other Inventions Bramah went on to create a hydrostatic machine (hydraulic press), a beer pump, the four-cock, a quill sharpener, a workingà planer, methods of paper-making, improved fire engines and printing machines.à In 1806, Bramah patented a machine for printing banknotesà that was used by the Bank of England. One of Bramahs last inventions was a hydrostatic press capable of uprooting trees. This was used at Holt Forest inà Hampshire. While superintending this work Bramah caught a cold, which led to pneumonia. He died at on December 9, 1814. He was buried in the churchyard of St. Marys,à Paddington . Bramah ultimately obtained 18 patents for his designs between 1778 and 1812. In 2006 a pub inà Barnsley was opened named the Joseph Bramah in his memory.
