DEVELOPMENTS

2. INTERCHANGEABLE PARTS
 Eli Whitney first
developed this idea in
1801
 This invention made it
so that if a product
part failed, another
could be ordered
without having to order
a whole new product
 Whitney first used this
idea with gun
parts, but production
was expensive and
dif ficult

3. RAILROAD
 Samuel Homfray funded the
development of a steam-
powered vehicle that would
replace the horse-drawn
wagons or carts on the
tramways
 This development began in
1803
 The vehicle was actually built
by Richard Threvithick

4. STEAMBOAT
 The steamboat was invented
by Rober t Fulton in 1 807
 -Fulton made the
Clermont, which was a vessel
that he put a steam engine in.
 -In 1 807, the Clermont went
up the Hudson River from New
York City to Albany.
 -The invention of the
steamboat completely
revolutionized America's
water ways, and made
traveling and transpor ting
goods much easier
 -The invention also helped in
opening the west and the
south, and made the
transpor t of manufactured
necessities quicker and
cheaper

5. COTTON GIN
 Eli Whitney invented
the cotton gin in
1793, but it was not
officially patented until
1807
 Was used to clean
cotton more efficiently
and quickly
 Revolutionized industry
because cotton could
be produced more
quickly and could
become a more stable
and useful crop for
Americans, thus
boosting the American
economy.

6. TIN CAN
 Peter Durand first
patented the tin can in
1810
 Brian Donkin and John
Hall opened the first tin
can producing factory
 Early cans were sealed
with lead which
ultimately lead to lead
poisoning
 This revolutionized the
food industry because
it helped to preserve
the food so it would not
go to waste

7. THE REAPER
 Invented by Cyrus
McCormick in 1831
 The reaper cut,
threshed, and bundled
grain.
 Was pulled through
the field by horses
 Increased grain
production in America;
farmers could produce
10 acres of grain a
day as opposed to the
previous 2 or 3

8. ELECTRIC STREETCAR
 Thomas Davenport
invented the first
electric motor in 1834
and a small electric
railway in 1835
 This demonstrated
technological advances
in America
 This invention was
dif ferent because it was
powered by an electric
motor, versus one that
runs on gasoline

9. STEEL PLOW
 -The steel plow was
invented by John Deere
 -It was invented in 1837
 -The original wooden
plows that were brought
over to Illinois would not
work on the thick
Midwestern soil, as they
were easily broken.
 -In 1837, Deere made a
steel plow that could get
through the thick soil
 -This invention made
farming in the Midwest
possible, and Deere went
into the business of
manufacturing plows.

10. TELEGRAPH
 -Invented by Samuel F. B. Mor se in
1 844
 -The telegraph was a new form of
communicati on that used pulses
of electricity to transmit
information over wires
 -Mor se recieved $30,000 from
Congress to fund his experiment
 - Alongside the telegraph Mor se
Code was invented, which was a
series of dots and dashes that
represented letter s in the
alphabet.
 -In 1 844, Mor se sent the message
"What hath God wrought?" from
Washington to Baltimore.
 -The telegraph revolutioni zed
communication, and by 1 854,
there were 23,000 miles of
telegraph wire in use.

11. SEWING MACHINE
 Invented by Elias Howe
in 1846
 New machine out
stitched five hand-
sewers and was known
for its speed
 Made producing
clothing quicker and
increased clothing
production in America
 At first, the idea didn’t
catch on, then Howe
struggled with
imitators trying to
steal his idea
