This document discusses the history and development of the steam engine. It describes how Thomas Savery first invented the steam engine in 1698, and how Thomas Newcomen and James Watt later improved upon the original design. The steam engine helped power the Industrial Revolution and transform technology, transportation, and society. However, steam engines also contributed to pollution and the inefficient use of energy.

 “If human thought is a growth, like all other growths, its
logic is without foundation of its own, and is only the
adjusting constructiveness of all other growing things. A
tree cannot find out, as it were, how to blossom, until
comes blossom-time. A social growth cannot find out the
use of steam engines, until comes steam-engine-time.” —

What Is a Steam Engine?
 Steam engine was first invented in the 1698 by an
English inventor, Thomas Savery. In which later in the
1711 it was improved by Thomas Newcomen he is
also an Englishman. Then again, in 1781 a Scottish
guy named James Watt improved the steam engine
that produce continuous rotative motion in which
later this engine became truly viable machinery that
helped start the Industrial Revolution in the 18th
century.
 Steam engine is an engine where it uses heats (by
boiling water) to build a high pressure force to
produce a mechanical motion.
 This was used for water pump and transportations.

Thomas Savery
 Thomas Savery was born in 1650, Shilstone,
Devinshire, England. And he was the first
person who successfully invented the steam
powered engine.
 He was a military engineer and he was a
mechanic lover.
 His first design was pretty simple in which it is
only can be used to pump water up of the
mines.
 Later on he decided to work together with
Thomas Newcomon after he got a patent tu run
this steam powered engine. Then they decided
to improve the steam engine to become more
advanced.

Thomas Newcomen
 He was born in 28th February 1664 in Dartmouth
Devon England.
 He was a British Engineer and one of the steam
engine developer.
 His initiative to develop the steam engine is
because as he was an ironmonger in his city and
running a water pump engine using horses power
to pump out the water from the Cornish tin
mines was too expensive.
 His new design was using piston instead of
vessels from Savery.
 Their innovation was really important in that time
to help the coal miners pumping up the water.

James Watt
 He was born in Greenock, Scotland 1736.
 He raised in the carpenter family and he loves
instruments.
 Later in 1755 he went to London to study
engineering. In which later he improved the
Newcomen’s steam engine design and
afterwards he met a guy named Matthew
Boulton, in which then they become a partner
and runs this business of steam engine together.
 His steam engine was working successfully and
even it can be used in transportation. Since
then the steam train was build and ships etc.
 It was really helping the Industrial revolution.

How Does It Work?

9. +
 Inside the locomotive cab, the coals are loaded in the firebox,
 The boiler is a big tank of water with dozens of thin metal tubes running
through it, in which it brings heat and smoke from the firebox to the
chimney to release them. As the heat is released from that tube, the
water in the tank is boiled.
 The steam from the water goes to the cylinder and giving a pressure
towards the piston right in front of the wheel.
 A little mechanical gate in the cylinder, known as an inlet valve lets the
steam in. The piston moves back and forth and as it is connected to the
wheel using crank and connecting rod, it able to moves the wheels.

Effects Towards…
 Innovation of Technology
 It helps the world into more modern era called Industrial revolution.
 Technology invention begins and things are being build rapidly. Such as
the locomotive steam engine.
 Social lifestyle
 Help jobs easier and cheaper.

11. +
What Are the Disadvantages
 High pressure steam which is dangerous.
 Giving too much pollution
 Too much energy is used to make the steam
