Joseph Br Amah, an English engineer, born at Stainborough, Yorkshire, April 13, 1749, died Dec. 9, 1814. He showed at an early age a remarkable mechanical ingenuity, was apprenticed to a carpenter, and subsequently removed to London, where he worked for a cabinetmaker, and afterward set up in the same business for himself. In 1784 he took out a patent for his widely renowned locks. Among many other inventions, he devised the hydraulic press, which is used not only in the ordinary mode of a press, but also for lifting enormous weights. He was the inventor of a mode of printing the number and date of bank notes used in the bank of England, by which the services of 100 clerks out of 120 were dispensed with. In 1812 he secured a patent for the construction of main pipes through the principal streets of a city, of sufficient strength to withstand great pressure to be applied by force pumps. The object of this invention was to provide the means of extinguishing fires without the aid of a fire engine.
