Washing machine was patented by Nathaniel Briggs in 1797. A fire in the patent office in 1836 destroyed all records of his patent. However, his patent probably resembled a current wash board.

First Parachute
Parachute jump was made for the first time in 1797. André-Jacques Garnerin dropped from a hot air balloon 3,200 feet above the city of Paris. His parachute resembled an umbrella. On the ascent, the parachute was closed. At the designated height, he cut the balloon away, opened the parachute, and landed with the gondola.
