Samuel Brown (engineer)

Samuel Brown was an English engineer and inventor, who developed in the early 19th century as one of the first internal combustion engine or gas engine with hydrogen as fuel. Brown, a cooper by trade ( he also improvements in machinery for the manufacture of drums and other containers patented ), was described as the "father of the gas turbine ." While he was in the Eagle Lodge lived in Brompton in west London from 1825 to 1835, he developed the first working gas turbine, which was a mechanical success. He built two machines for demonstration purposes on the grounds of the lodge.

Brown's Gas Engine

In two patents on 4 December 1823 to April 22, 1826 Brown proposed to fill an enclosed chamber with a gas flame and then expel the air; then he dropped his flame by injecting water and operating a turbine during inflow of air into the resulting partial vacuum. The idea was clearly copied by James Watt's steam engine, wherein it is used a flame instead of steam, in order to generate the vacuum.

Brown later designed (by 1826) a machine that used hydrogen as fuel - an early example of an internal combustion engine. It was based on an old steam engine by Thomas Newcomen, had a separate combustion and working cylinders, and was cooled with water circulating in a jacket or lining around the cylinder. The water was kept in motion by a pump and cooled in contact with the outside air. 1825 Brown founded a company to produce the machine. She had a displacement of 8800 cc, but reached only 4 hp. He tested the machine by on May 27th, 1826 thus drive a vehicle that drove the Shooter's Hill up. The great effort that was needed to operate the gas vacuum machine, but prevented their application.

The machine was also used to pump water and drive a river boat. Brown founded a company to produce machines for boats and barges, one of which is a speed of 8 miles per hour to have upstream reaches. The company was not successful, although this might have more located on the gas supply than on the machine itself
