The automobile as we know it was not invented in a
single day by a single inventor. The history of the automobile reflects an
evolution that took place worldwide. It is estimated that over 100,000 patents
created the modern automobile. However, we can point to the many firsts that
occurred along the way. Starting with the first theoretical plans for a motor
vehicle that had been drawn up by both Leonardo da Vinci and Isaac Newton.
In 1769, the very first
self-propelled road vehicle was a military tractor invented by French engineer
and mechanic, Nicolas Joseph Cugnot (1725 - 1804). Cugnot used a steam engine to
power his vehicle, built under his instructions at the Paris Arsenal by mechanic
Brezin. It was used by the French Army to haul artillery at a whopping speed of
2 1/2 mph on only three wheels. The vehicle had to stop every ten to fifteen
minutes to build up steam power. The steam engine and boiler were separate from
the rest of the vehicle and placed in the front (see engraving above). The
following year (1770), Cugnot built a steam-powered tricycle that carried four
passengers.
In 1771, Cugnot drove one of his road
vehicles into a stone wall, making Cugnot the first person to get into a motor
vehicle accident. This was the beginning of bad luck for the inventor. After one
of Cugnot's patrons died and the other was exiled, the money for Cugnot's road
vehicle experiments ended. Steam engines powered cars by burning fuel that
heated water in a boiler, creating steam that expanded and pushed pistons that
turned the crankshaft, which then turned the wheels. During the early history of
self-propelled vehicles - both road and railroad vehicles were being developed
with steam engines. (Cugnot also designed two steam locomotives with engines
that never worked well.) Steam engines added so much weight to a vehicle that
they proved a poor design for road vehicles; however, steam engines were very
successfully used in locomotives. Historians, who accept that early
steam-powered road vehicles were automobiles, feel that Nicolas Cugnot was the
inventor of the first automobile.
After Cugnot Several Other Inventors
Designed Steam-Powered Road Vehicles
-
Cugnot’s vehicle was improved by
Frenchman, Onesiphore Pecqueur, who also invented the first differential gear.
-
In 1789, the first U.S. patent for a
steam-powered land vehicle was granted to Oliver Evans.
-
In 1801, Richard Trevithick built a
road carriage powered by steam - the first in Great Britain.
-
In Britain, from 1820 to 1840,
steam-powered stagecoaches were in regular service. These were later banned from
public roads and Britain's railroad system developed as a result.
-
Steam-driven road tractors (built by
Charles Deitz) pulled passenger carriages around Paris and Bordeaux up to 1850.
-
In the United States, numerous steam
coaches were built from 1860 to 1880. Inventors included: Harrison Dyer, Joseph
Dixon, Rufus Porter, and William T. James.
-
Amedee Bollee Sr. built advanced
steam cars from 1873 to 1883. The "La Mancelle" built in 1878, had a
front-mounted engine, shaft drive to the differential, chain drive to the rear
wheels, steering wheel on a vertical shaft and driver's seat behind the engine.
The boiler was carried behind the passenger compartment.
-
In 1871, Dr. J. W. Carhart, professor
of physics at Wisconsin State University, and the J. I. Case Company built a
working steam car that won a 200-mile race.
Early Electric Cars-Steam engines were not the only
engines used in early automobiles. Vehicles with electrical engines were also
invented. Between 1832 and 1839 (the exact year is uncertain), Robert Anderson
of Scotland invented the first electric carriage. Electric cars used
rechargeable batteries that powered a small electric motor. The vehicles were
heavy, slow, expensive, and needed to stop for recharging frequently. Both steam
and electric road vehicles were abandoned in favor of gas-powered vehicles.
Electricity found greater success in tramways and streetcars, where a
constant supply of electricity was possible. However, around 1900,
electric land vehicles in America outsold all other types of cars. Then
in the several years following 1900, sales of electric vehicles took a nosedive
as a new type of vehicle came to dominate the consumer market.
