The early history of the steam.
Thomas
Newcomen (1663-1729) built the first steamengine
He made use of the effect of condensation of steam in
the cylinder. During the condensation the pressure in
the cylinder drops and the plunger is pushed inside by
the atmospheric pressure around the cylinder. (The condensation
could be easened by spraying water over the cylinder and
plunger)
As far as is known, the first engine of the socalled Newcomen
type was built in 1712. In the early 20th century still
some of these engines
were in operation.
It was the Scottish engineer James Watt (1736-1819) who
developed the “modern” steam engine, approx
50 years after the invention of the Newcomen engine.
As you can understand this invention boosted the industrial
revolution and mechanisation of human labour.
The engines designed by James Watt had a higher reliability
and were stronger. Another advantage was that the power
could be withdrawn from a rotating axis. The engine of
Newcomen had no rotating movement. The efficiency of the
Watt engine was much higher, a saving in fuel (coal) consumption
up to 75% was obtained.
It was especially in England where this industrial revolution
commenced already around 1700, and from other parts of
the world many people visited England to study all these
developments.
An example is the construction of the first iron bridge
over the river Severn: with a length of 43 meters it crossed
the gorge of the river. This was realised by Abraham Darby
III in 1779.
The bridge still exists near the village “Iron Bridge”
named after this bridge
Nearly 70 years before this bridge was built it was discovered
in the village Coalbrookdale that melting iron ore with
coal produced iron. 
The process was developed by Abraham Darby 1 in 1709 and
can be seen as an important step in the birth of the Industrial
Revolution. Abraham Darby founded the Bristol Iron Company
and from 1712 all steamcylinders used Newcomen were casted
here. In 1759 already 200 steamcylinders were casted by
the Iron Company for Newcomen. The village Coalbrookdale
in the valley of the Severn near Blist Hill was in these
days a centre of industrial activities and new developments.
Coalmines and iron ore mines formed the basis of the iron
industry. The first steampump used to remove water from
the mineshafts was installed in 1790. For the iron blast
furnaces which required large amounts of air, the first
steamdriven aircompressors were developed and constructed
in 1840. Also a lot of steamengines were installed for
the elevators of the mineshafts.
In this area the first cast iron steamengines were constructed
and the first iron ships were built.
It was also in this period that the engineer Richard Trevithick
(1771-1833) from Cornwall built the first steamlocomotive
in 1803-1804.
The first steamlocomotive that could be used more practically
was built by George Stephenson (1781-1848) in 1814. The
engine had a weight of 30 ton and could develop a speed
of 4 miles/hour.
When the mines near Coalbrookdale and Iron Bridge were
exhausted, the industrial boom came to a stop. In 1912
the blast furnaces were
blasting for the last time. It had played its role as
a leader in the industrial revolution.
At
other places the industrial activities went on.
The development of the first stream driven traction
engine started in 1857 in the premises of the firm Garrett.
Portable engines which could not drive themselves, were
already known since 1839/1840 and were used as the basis
for the first self moving engine: traction engine.
This first step led to the development of the other
wellknown steamengines like rollers, traction engines
for general use and special purposes like the heavy
road loco’s and showmans engines. Ploughing engines
are another example.
The development of the road loco was possible in a later
stage, after modifying the traffic act (the “locomotive
act”) in 1904.
In the early twentieth century started the development
of steamdriven cars for transport of persons and freightlorries.
These looked already very much like the lorries as we
know them. Speeds up too 70 km/hr (nearly 50 mph) were
normal.
It is this history of the development of the industrial
revolution in England which has my interest and from
which you can find pictures and descriptions on my “steamwebsite”.
It is an era which is called sometimes the “good
old days” In how far this is true, I have sometimes
my doubts!
From
the many tenth-thousands of steam engines which were
once in operation, nowadays the number is reduced to
the hundreds which still exist. It was after the second
world war that people started to show interest in these
engines to keep them for the future generation instead
of scrapping them or sending them to the steel furnaces.
Many engines are nowadays restored and brought back
in operation by steam enthousiasts. On steam events,
or rallies as they are also called, these engines do
revive the past. Started in England, these rallies are
nowadays also more and more popular in Continental Europe.
The disadvantage of this revival is that the value of
these engines, once at kilogram scrap price, is nowadays
sometimes many times the value of a luxurious topclass
automobile. However, this is in principle only a fraction
of the historical value. Many steamlovers share the
opinion with me that these engines have to be treated
with respect, built in a period that craftsman workmanship
and manual labour were the basis of constructing them.
For example, in 1891 the Fowler works, wellknown from
traction engines and ploughing engines, employed approximately
1600 men. Many techniques, developed in the steamera,
are still used in modern technology. An example is the
differential 1), applied in several types of traction
engines, is now applied in every automobile. Many steampeople
have contributed to the preservation of engines, so
we can still see and experience how the industrial revolution
was started and grew, the basis of our industrial society
nowadays.

Differential: a mechanical construction which enables
the powered wheels of a car to rotate with different
speeds. Of importance for steering the car through bends
With
this website I hope to contribute to keep the interest
alive for the workhorses of the 19th and early 20th
century.
I hope you enjoy it!
