Everything about Samuel Brown Engineer totally explained
This article is about the English engineer and inventor. See Samuel Brown for other persons of the same name.
Samuel Brown was an
English engineer and
inventor credited with developing one of the earliest examples of an
internal combustion engine, during the early
19th century.
Brown, a
cooper by training (he also patented improvements to machinery
for manufacturing casks and other vessels), has been described as the 'father of the gas engine'. While living at Eagle Lodge in the
Brompton area of west
London, from
1825 to
1835, he developed 'the first gas engine that unquestionably did actual work and was a mechanical success'. He set up two engines for demonstration purposes in the grounds of the Lodge.
Internal combustion engine
In patents dated
4 December 1823 and
22 April 1826,, Brown proposed to fill a closed chamber with a gas flame, and so expel the air; then he condensed the flame by injecting water, and operated an air engine by exhausting into the partial vacuum so obtained. The idea was evidently suggested by
James Watt's
condensing steam engine, flame being employed instead of steam to obtain a vacuum.
Brown later designed an engine that used
hydrogen as a
fuel -- an early example of an
internal combustion engine. It was based on an old
Newcomen steam engine, had a separate
combustion and working
cylinders, and was cooled by water contained within a casing or cylinder lining, circulated around the cylinders (water was constantly kept moving through the action of a pump and was recooled by contact with outside air). It had a capacity of 8,800 cc but was rated at only 4 hp. He tested the engine by using it to propel a vehicle up
Shooter's Hill on
27 May 1826.
» "In 1826, Mr. Samuel Brown applied his gas-vacuum engine ... to a carriage, and ascended Shooter's hill to the satisfaction of numerous spectators. The great expense, however, which attended the working of a gas-vacuum engine, prevented its adoption.
The engine was also employed to pump water and to propel river boats. Brown formed a company to produce engines for boats and barges, one of which is said to have achieved a speed of 8mph upstream. The company was unsuccessful, although this may have been due concerns about obtaining adequate supplies of the gas fuel rather than concerns about the engines.
