Steam Power The Industrial Revolution
2
18th Century Timeline, 1700 - 1799
  • The Technology, Science and Inventions

3
Introduction
  • 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.

4
Introduction
  • 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.

5
Industrial Revolution Timeline of Textile
Machinery
  • Several inventions in textile machinery occurred
    in a relatively short time period during the
    Industrial Revolution.

6
Timeline 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.

7
Timeline 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.

8
Timeline 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.

9
Timeline 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.

10
1712 - 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.

1733 - 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.

1764 - 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.

1769 - 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.

1769 - 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.

1779 - 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.

1785 - 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.

1830 - 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.

The History of Steam Engines
  • Thomas Savery
  • Thomas Newcomen
  • James Watt

30
Thomas 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.

31
Thomas 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.

33
Thomas 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.

34
Thomas 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.

36
James 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.

37
James 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.

39
Progress 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.

40
Atmospheric 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.

How Steam Engines Work
46
How 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.

47
How 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.

48
How 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.

49
How 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.

50
How 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.

51
Steam 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.

52
Steam Engine Operation
53
Steam 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.

55
Boilers
  • 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

56
Fire-tube Boiler
57
Boilers
  • 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

58

59
Boilers
  • 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.

60
Conclusion
  • 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.

61
Conclusion
  • 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.
