Samuel Brown

Samuel Brown was an English The area now called England has been settled by people of various cultures for about 35,000 years, but it takes its name from the Angles, one of the Germanic tribes who settled during the 5th and 6th centuries. England became a unified state in AD 927, and since the Age of Discovery, which began during the 15th century, has had a significant engineer An engineer is a professional practitioner of engineering, concerned with applying scientific knowledge, mathematics and ingenuity to develop solutions for technical problems. Engineers design materials, structures, machines and systems while considering the limitations imposed by practicality, safety and cost. The word engineer is derived from and inventor An invention is a new composition, device, or process. An invention may be derived from a pre-existing model or idea, or it could be independently conceived in which case it may be a radical breakthrough. In addition, there is cultural invention, which is an innovative set of useful social behaviors adopted by people and passed on to others credited with developing one of the earliest examples of an internal combustion engine The internal combustion engine is an engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber. In an internal combustion engine the expansion of the high temperature and pressure gases, which are produced by the combustion, directly applies force to a movable component of the engine, such as the, during the early 19th century.

Brown, a cooper Traditionally, a cooper is someone who makes wooden staved vessels of a conical form, of greater length than breadth, bound together with hoops and possessing flat ends or heads. Examples of a cooper's work include but are not limited to casks, barrels, buckets, tubs, butter churns, hogsheads, firkins, tierces, rundlets, puncheons, pipes, tuns, by training (he also patented improvements to machinery for manufacturing casks and other vessels),[1] has been described as the 'father of the gas engine'. While living at Eagle Lodge in the Brompton Brompton is a locality in the Royal Borough of Kensington and Chelsea. It is roughly defined by the triangle of Brompton Road, Sloane Street and Sloane Avenue area of west London London is a leading global city, the world's largest financial centre alongside New York, and has the largest city GDP in Europe. Central London is home to the headquarters of most of the UK's top 100 listed companies and more than 100 of Europe's 500 largest. London's influence and strengths in the arts, education, entertainment, fashion, finance,, 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.[2]

Brown's Gas Vacuum Engine

In patents dated 4 December 1823 and 22 April 1826,[3], 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 James Watt, FRS, FRSE was a Scottish inventor and mechanical engineer whose improvements to the Newcomen steam engine were fundamental to the changes brought by the Industrial Revolution in both the Kingdom of Great Britain and the world's condensing steam engine A steam engine is a heat engine that performs mechanical work using steam as its working fluid, flame being employed instead of steam to obtain a vacuum.

Brown later designed an engine that used hydrogen Hydrogen is the chemical element with atomic number 1. It is represented by the symbol H. With an average atomic weight of 1.00794 u (1.007825 u for Hydrogen-1), hydrogen is the lightest and most abundant chemical element, constituting roughly 75 % of the Universe's elemental mass. Stars in the main sequence are mainly composed of hydrogen in its as a fuel Fuel is any material that can be used to generate energy to produce mechanical work in a controlled manner. The processes used to convert fuel into energy include chemical reactions, such as combustion, and nuclear reactions, such as nuclear fission or nuclear fusion. Fuels are also used in the cells of organisms in a process known as metabolism -- an early example of an internal combustion engine The internal combustion engine is an engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber. In an internal combustion engine the expansion of the high temperature and pressure gases, which are produced by the combustion, directly applies force to a movable component of the engine, such as the. It was based on an old Newcomen steam engine The atmospheric engine invented by Thomas Newcomen in 1712, today referred to as a Newcomen steam engine , was the first practical device to harness the power of steam to produce mechanical work. Newcomen engines were used throughout Britain and Europe, principally to pump water out of mines, starting in the early 18th century. James Watt's later, had a separate combustion Combustion or burning is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species. The release of heat can result in the production of light in the form of either glowing or a flame. Fuels of interest often include organic compounds in the gas, liquid or and working cylinders A cylinder is the central working part of a reciprocating engine, the space in which a piston travels. Multiple cylinders are commonly arranged side by side in a bank, or engine block, which is typically cast from aluminum or cast iron before precision features are machined into it. The cylinders may then be lined with sleeves or liners of some, 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).[4] It had a capacity of 8,800 cc but was rated at only 4 hp.[5] He tested the engine by using it to propel a vehicle up Shooter's Hill Shooter's Hill is a place, and an electoral ward in the London Borough of Greenwich in south-east London. It lies east of Blackheath and west of Welling, south of Woolwich and north of Eltham. It is one of the highest points in London on 27 May 1826.[6][7]

"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.[8]

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 8 mph upstream.[9][10] The company was unsuccessful,[11] although this may have been due concerns about obtaining adequate supplies of the gas fuel rather than concerns about the engines[citation needed].
