About this ebook

In this book, Stan Yorke explains the history of the steam engine and the enormous variety of uses to which it was put. There are over 50 photographs, plus detailed diagrams. Steam engines with their hissing pistons, revolving wheels and smell of oil and coal smoke have an irresistible attraction for many of us. The realisation that steam could be used to power machinery became one of the great Eureka moments of history—comparable to the discovery of iron and the invention of the printing press. It was steam-powered engines of all kinds that drove the vast industrial expansion during the 19th century. They featured in almost every aspect of life. They made possible the excavation of deep mines, the forward thrust of ships through the oceans and the propulsion of trains along the tracks of the world’s railways.

INDEX

Introduction

Today we have become so used to a regular stream of new products and developments that it is very easy to forget that our progress over the centuries has been marked by a small number of inventions of enormous importance. These have often arrived gradually without that Eureka! moment for historians to write about and record. The discovery of iron was one; the invention, for want of a better word, of steel (which predates the Roman Empire and which over time led to the steel we all rely on today) would certainly be another. So would printing, held by many as the greatest single invention made by man. The steam engine possibly also deserves to be on such a list for without it the Industrial Revolution would have petered out with just the canals and some very impressive water wheels.

Pre-steam factory power, locked to a good stream or river and dependent on the weather, but relatively cheap.

Whilst to most of us today the term ‘steam engine’ probably means a railway locomotive, in fact throughout the 19th century it featured in almost every aspect of life. It enabled deep mines to produce the extraordinary quantities of coal that kept industry working and our homes warm. It drove the factories that made Britain the leading industrial nation of the century and by the 1880s it powered ships, canal boats, cars, buses and trams as well. All these activities have long passed over to the internal combustion engine or to electricity. Here is one of life’s little surprises, for whilst the steam engine drove the first electricity generators – it still does! Roughly half of the world’s electricity is still produced courtesy of the steam engine, including almost all of our supplies here in Britain.

Two examples of the basic workshop engine (see Chapter 3).

Both can be regularly seen working in the Markham Grange Steam Museum, near Doncaster.

In this book I have used a fairly wide definition of the term ‘steam engine’. Basically, if a machine takes steam as its input and produces mechanical movement as its output then it is a steam engine. I want to follow the story of these machines from their shaky start, through the frantic 19th century to the birth of mechanical transport and on to today’s turbines.

CHAPTER 1

How It All Started

The seeds were sown a long way back in time. Hero of Alexandria had understood that gases expand and contract when heated and cooled. In 1606 the pressure of steam lifting water had been demonstrated, as had the force of a vacuum, though the reason for this wasn’t understood. Nearly 40 years were to pass before it was realized that the atmosphere had weight and it was this that produced the power, not the vacuum itself. Further people experimented, slowly adding to the understanding of gases, until in 1690 Denis Papin used condensing steam to draw a piston into a cylinder. Though he only made an experimental model with a piston just 2½ inches in diameter he had in fact demonstrated the first atmospheric engine.

FIG 1.1: In 1698 the Cornish engineer Savery patented a machine for ‘Raising of Water by the Impellant Force of Fire’ aimed at pumping water out of mine workings.

I must mention the work of Thomas Savery for, though his work led to
