STEAM

Master Li and I discovered that The Elsecar Heritage Railway do steam hauled Cream Teas on Wednesdays during the month of August. This naturally appealed to two gentlemen of taste and discernment like Li and myself, so yesterday we went over the border into South Yorkshire to partake of this delight. The trip, and cream tea, were excellent, they even trundled to and fro for a while to make up for the shortness of the line and to give passengers time for a second cup of tea.

Two other things played a part in the decision to make the trip. First was that we wanted to see in the flesh the legendary ‘Mardy Monster’, the most powerful Industrial loco ever to work in Britain. Secondly we wanted to see the Newcomon Engine, the only one still on it’s original site anywhere in the world. Been there since 1795 and ran until 1923. Puts todays throw away culture to shame, especially with all that guff about saving the planet.

Images from a book I have had for a while but only got the opportunity to give it a proper read while on a trip the past weekend.

The book is: A History of the Growth of the Steam Engine by Robert H. Thurston. Published in 1886.

It is available from Project Gutenberg here.

The images represent (clockwise from top left): Savery’s Engine (1702), Newcomen’s Engine (1705), Fly-ball governor (circa 1780), Boulton & Watt’s Double-Acting Engine (1784) and Corliss Engine (circa 1850).

Scottish inventor and mechanical engineer,James Watt died on 19 August 1819.
Watt was born in Greenock on 18 January 1736. His father was a prosperous shipwright. Watt initially worked as a maker of mathematical instruments, but soon became interested in steam engines.
The first working steam engine had been patented in 1698 and by the time of Watt’s birth, Newcomen engines were pumping water from mines all over the country. In around 1764, Watt was given a model Newcomen engine to repair. He realised that it was hopelessly inefficient and began to work to improve the design. He designed a separate condensing chamber for the steam engine that prevented enormous losses of steam. His first patent in 1769 covered this device and other improvements on Newcomen’s engine.
Watt’s partner and backer was the inventor John Roebuck. In 1775, Roebuck’s interest was taken over by Matthew Boulton who owned an engineering works in Birmingham. Together he and Watt began to manufacture steam engines. Boulton & Watt became the most important engineering firm in the country, meeting considerable demand. Initially this came from Cornish mine owners, but extended to paper, flour, cotton and iron mills, as well as distilleries, canals and waterworks. In 1785, Watt and Boulton were elected fellows of the Royal Society.
By 1790, Watt was a wealthy man and in 1800 he retired and devoted himself entirely to research work. He patented several other important inventions including the rotary engine, the double-action engine and the steam indicator, which records the steam pressure inside the engine.
