Title: Steam Power &
1Steam Power The Industrial Revolution
218th Century Timeline, 1700 - 1799
- The Technology, Science and Inventions
3Introduction
- The 18th century (also referred to as the 1700s)
began the first Industrial Revolution. Modern
manufacturing began with steam engines replacing
animal labor. The 18th century saw the widespread
replacement of manual labor by new inventions and
machinery. - The 18th century was also part of the "The Age of
Enlightenment", an historical period
characterized by a change away from traditional
religious sources of authority, and a move
towards science and rational thought.
4Introduction
- The effects of the 18th century Enlightenment led
to the American Revolutionary War and the French
Revolution. The 18th century saw the spread of
capitalism and the increased availability of
printed materials.
5Industrial Revolution Timeline of Textile
Machinery
- Several inventions in textile machinery occurred
in a relatively short time period during the
Industrial Revolution.
6Timeline of Textile Machinery
- 1733 Flying shuttle invented by John Kay - an
improvement to looms that enabled weavers to
weave faster. - 1742 Cotton mills were first opened in England.
- 1764 Spinning jenny invented by James Hargreaves
- the first machine to improve upon the spinning
wheel. - 1764 Water frame invented by Richard Arkwright -
the first powered textile machine.
7Timeline of Textile Machinery
- 1769 Arkwright patented the water frame.
- 1770 Hargreaves patented the Spinning Jenny.
- 1773 The first all-cotton textiles were produced
in factories. - 1779 Crompton invented the spinning mule that
allowed for greater control over the weaving
process. - 1785 Cartwright patented the power loom. It was
improved upon by William Horrocks, known for his
invention of the variable speed batton in 1813.
8Timeline of Textile Machinery
- 1787 Cotton goods production had increased 10
fold since 1770. - 1789 Samuel Slater brought textile machinery
design to the US. - 1790 Arkwright built the first steam powered
textile factory in Nottingham, England. - 1792 Eli Whitney invented the cotton gin - a
machine that automated the separation of
cottonseed from the short-staple cotton fiber.
9Timeline of Textile Machinery
- 1804 Joseph Marie Jacquard invented the Jacquard
Loom that weaved complex designs. Jacquard
invented a way of automatically controlling the
warp and weft threads on a silk loom by recording
patterns of holes in a string of cards. - 1813 William Horrocks invented the variable speed
batton (for an improved power loom). - 1856 William Perkin invented the first synthetic
dye.
101712 - Newcomen Steam Engine and the Industrial
Revolution
- In 1712, Thomas Newcomen, together with John
Calley built their first steam engine on top of a
water-filled mine shaft and used it to pump water
out of the mine. The Newcomen steam engine was
the predecessor to the Watt steam engine and it
was one of the most interesting pieces of
technology developed during the 1700s. The
invention of engines, the first being steam
engines, was very important to the Industrial
Revolution.

121733 - Flying Shuttle, Automation of Textile
Making The Industrial Revolution
- In 1733, John Kay invented the flying shuttle, an
improvement to looms that enabled weavers to
weave faster. - By using a flying shuttle, a single weaver could
produce a wide piece of cloth. The original
shuttle contained a bobbin on to which the weft
(weaving term for the crossways yarn) yarn was
wound. It was normally pushed from one side of
the warp (weaving term for the the series of
yarns that extended lengthways in a loom) to the
other side by hand. Before the flying shuttle
wide looms needed two or more weavers to throw
the shuttle.
13- The automation of making textiles (fabrics,
clothing, etc.) marked the beginning of the
Industrial Revolution.
14Flying Shuttle
151764 - Increased Yarn and Thread Production
During Industrial Revolution
- In 1764, a British carpenter and weaver named
James Hargreaves invented an improved spinning
jenny, a hand-powered multiple spinning machine
that was the first machine to improve upon the
spinning wheel by making it possible to spin more
than one ball of yarn or thread. Spinner machines
like the spinning wheel and the spinning jenny
made the threads and yarns used by weavers in
their looms. As weaving looms became faster,
inventors had to find ways for spinners to keep
up.
16Spinning Jenny
171769 - James Watt's Improved Steam Engine Powers
the Industrial Revolution
- James Watt was sent a Newcomen steam engine to
repair that led him to invent improvements for
steam engines. - Steam engines were now true reciprocating engines
and not atmospheric engines. Watt added a crank
and flywheel to his engine so that it could
provide rotary motion. Watt's steam engine
machine was four times more powerful than those
engines based on Thomas Newcomen's steam engine
design.

211769 - Spinning Frame or Water Frame
- Richard Arkwright patented the spinning frame or
water frame that could produce stronger threads
for yarns. The first models were powered by
waterwheels so the device came to be first known
as the water frame. - It was the first powered, automatic and
continuous textile machine and it enabled the
move away from small home manufacturing towards
factory production of textiles. The water frame
was also the first machine that could spin cotton
threads.
22Spinning Frame or Water Frame
231779 - Spinning Mule Increased Variety in Threads
and Yarns
- In 1779, Samuel Crompton invented the spinning
mule that combined the moving carriage of the
spinning jenny with the rollers of the water
frame. - The spinning mule gave the spinner great control
over the weaving process. Spinners could now make
many different types of yarn. Finer cloths could
now be made.
24Spinning Mule
251785 - Power Loom's Effect on the Women of the
Industrial Revolution
- The power loom was a steam-powered, mechanically
operated version of a regular loom. A loom is a
device that combines threads to make cloth. - When the power loom became efficient, women
replaced most men as weavers in the textile
factories.
26Power Loom
271830 - Practical Sewing Machines Ready Made
Clothing
- After the sewing machine was invented, the
ready-made clothing industry took off. Before
sewing machines, nearly all clothing was local
and hand-sewn. - The first functional sewing machine was invented
by the French tailor, Barthelemy Thimonnier, in
1830. - About 1831, George Opdyke was one of the first
American merchants to begin the small-scale
manufacture of ready-made clothing. But it was
not until after the power-driven sewing machine
was invented that factory production of clothes
on a large scale occurred.

29The History of Steam Engines
- Thomas Savery
- Thomas Newcomen
- James Watt
30Thomas Savery (1650-1715)
- Thomas Savery was an English military engineer
and inventor who in 1698, patented the first
crude steam engine, based on Denis Papin's
Digester or pressure cooker of 1679. - Thomas Savery had been working on solving the
problem of pumping water out of coal mines. His
machine consisted of a closed vessel filled with
water into which steam under pressure was
introduced. This forced the water upwards and out
of the mine shaft. Then a cold water sprinkler
was used to condense the steam. This created a
vacuum which sucked more water out of the mine
shaft through a bottom valve.
31Thomas Savery
- Thomas Savery later worked with Thomas Newcomen
on the atmospheric steam engine. Among Savery's
other inventions was an odometer for ships, a
device that measured distance traveled.
32Illustration of Thomas Savery's Engine circa 1698
33Thomas Newcomen (1663-1729)
- Thomas Newcomen was an English blacksmith who
invented the atmospheric steam engine, an
improvement over Thomas Slavery's previous
design. - The Newcomen steam engine used the force of
atmospheric pressure to do the work. Thomas
Newcomen's engine pumped steam into a cylinder.
The steam was then condensed by cold water, which
created a vacuum on the inside of the cylinder.
The resulting atmospheric pressure operated a
piston, creating downward strokes. In Newcomen's
engine the intensity of pressure was not limited
by the pressure of the steam, unlike what Thomas
Savery had patented in 1698.
34Thomas Newcomen
- In 1712, Thomas Newcomen, together with John
Calley built their first engine on top of a
water-filled mine shaft and used it to pump water
out of the mine. The Newcomen engine was the
predecessor to the Watt engine and it was one of
the most interesting pieces of technology
developed during the 1700s.
35Thomas Newcomens Engine
36James Watt (1736-1819)
- James Watt was a Scottish inventor and mechanical
engineer, born in Greenock, who was renowned for
his improvements of the steam engine. In 1765,
James Watt, while working for the University of
Glasgow was assigned the task of repairing a
Newcomen engine, which was deemed inefficient but
the best steam engine of its time. That started
the inventor to work on several improvements to
Newcomen's design.
37James Watt
- Most notable was Watt's 1769 patent for a
separate condenser connected to a cylinder by a
valve. Unlike Newcomen's engine, Watt's design
had a condenser that could be cool while the
cylinder was hot. Watt's engine soon became the
dominant design for all modern steam engines and
helped bring about the Industrial Revolution. - A unit of power called the Watt was named after
James Watt. The Watt symbol is W, and it is equal
to 1/746 of a horsepower, or one Volt times one
Amp.
38Engraving of James Watt
39Progress of the Atmospheric Steam Engine
- The atmospheric engine, as first designed, had a
slow process of condensation by the application
of the condensing water to the exterior of the
cylinder. Producing the vacuum caused the strokes
of the engine to take place at very long
intervals. - More improvements were made which immensely
increased the rapidity of condensation. Thomas
Newcomen's first engine produced 6 or 8 strokes a
minute and he improved that to 10 or 12 strokes.
40Atmospheric Steam Engine
- In the following diagram, the steam was generated
in the boiler A. The piston P moved in a cylinder
B. When the valve V was opened, the steam pushed
up the piston. At the top of the stroke, the
valve was closed, the valve V' was opened, and a
jet of cold water from the tank C was injected
into the cylinder, thus condensing the steam and
reducing the pressure under the piston. The
atmospheric pressure above then pushed the piston
down again.

45How Steam Engines Work
46How Steam Engines Work
- A steam engine is a device that converts the
potential energy that exists as pressure in
steam, and converts that to mechanical force.
Early examples were the steam locomotive trains
and steamships that relied on these steam engines
for movement. The Industrial Revolution came
about primarily because of the steam engine. The
thirty seconds or so required to develop pressure
made steam less favored for automobiles, which
are generally powered by internal combustion
engines.
47How Steam Engines Work
- The first steam device was invented by Hero of
Alexandria, a Greek, before 300BC, but never
utilized as anything other than a toy. While
designs had been created by varous people in the
meanwhile, the first practical steam engine was
patented by James Watt, a Scottish inventor, in
1769. Steam engines are of various types but most
are reciprocal piston or turbine devices.
48How Steam Engines Work
- The strength of the steam engine for modern
purposes is in its ability to convert raw heat
into mechanical work. Unlike the internal
combustion engine, the steam engine is not
particular about the source of heat. Since the
oxygen for combustion is unmetered, steam engines
burn fuel cleanly and efficiently, with
relatively little pollution.
49How Steam Engines Work
- One source of inefficiency is that the condenser
causes losses by being somewhat hotter than the
outside world. Thus any closed-cycle engine will
always be somewhat less efficient than any
open-cycle engine, because of condenser losses.
50How Steam Engines Work
- Most notably, without the use of a steam engine
nuclear energy could not be harnessed for useful
work, as a nuclear reactor does not directly
generate either mechanical work or electrical
energy - the reactor itself does nothing but sit
there and get hot. It is the steam engine which
converts that heat into useful work.
51Steam Engine Operation
- The following diagram shows the major components
of a piston steam engine. This sort of engine
would be typical in a steam locomotive. - The engine shown is a double-acting steam engine
because the valve allows high-pressure steam to
act alternately on both faces of the piston.
52Steam Engine Operation
53Steam Engine Operation
- You can see that the slide valve is in charge of
letting the high-pressure steam into either side
of the cylinder. The control rod for the valve is
usually hooked into a linkage attached to the
cross-head, so that the motion of the cross-head
slides the valve as well. - The following animation shows the engine in
action.
54Steam Engine Operation

55Boilers
- The high-pressure steam for a steam engine comes
from a boiler. The boiler's job is to apply heat
to water to create steam. There are two
approaches fire tube and water tube. - A fire-tube boiler was more common in the 1800s.
It consists of a tank of water perforated with
pipes. The hot gases from a coal or wood fire run
through the pipes to heat the water in the tank,
as shown here
56Fire-tube Boiler
57Boilers
- In a fire-tube boiler, the entire tank is under
pressure, so if the tank bursts it creates a
major explosion. - More common today are water-tube boilers, in
which water runs through a rack of tubes that are
positioned in the hot gases from the fire. The
following simplified diagram shows you a typical
layout for a water-tube boiler
58Water-tube Boiler
59Boilers
- In a real boiler, things would be much more
complicated because the goal of the boiler is to
extract every possible bit of heat from the
burning fuel to improve efficiency.
60Conclusion
- Early steam engines had limited application
because of design limitations. - The first applications were in mines for
ventilation and pumping out water. - As time passed improvements in steam engine
design opened up new possibilities for steam
engine applications. - Britains textile industry was the first to be
mechanized by steam engines.
61Conclusion
- As steam engines were applied to new applications
more design improvements were made. - This increased productivity greatly.
- Steam engines were then applied to railways and
steamships. - Because Britain industrialized first it became
the strongest world power, despite its size as a
tiny island nation. - The Industrial Revolution spread and other
countries eventually overtook Britain in
industrial capacity.
