P.B Downing came out with the first mailbox design
In 1891 the procedure for mailing just got better. P. B. Downing
design a metal box with 4 legs and got it patented October 27 1891.
Downing called it a street letter box and is a form of what today’s
mailbox is like. So if you ever feel too tired to get into your car and
mail off your letters, he just saved you a trip. Marvelous!
But it does not stop there- P.B. Downing also designed an
electrical switch for railroads which allowed railroad workers
to supply shut off powers to trains at certain times.
Because of his design, inventors would be able to create
electrical switches like light switches in the home.
