Sarah Boone
  • In 1892, Sarah Boone invented the ironing board
    in New Haven, Connecticut.
  • Sarah Boones ironing board was narrow and
    curved, and it was also reversible.  Making the
    ironing board reversible made it easy to iron
    both sides of a sleeve.
  • Sarah Boone was one of the first African American
    women to ever receive a patent for an invention.

Lewis Latimer
  • In 1881, Latimer received a patent for inventing
    the carbon filament for the electric light bulb.
    This filament made it cheaper and safer to use
    the light bulb.
  • Latimer invented the flushing water closet, now
    called a toilet, for railway trains.
  • Latimer also created the threaded socket, which
    allows the bulb to screw into a fixture.

    rotation method, which revolutionized southern
    agriculture.
  • Carver invented 325 uses for the peanut.
  • From common clays, he created dyes and paints.
  • Carver looked at ways of using the sweet potato
    and was able to develop more than 115 products
    from it including flour and starch (the United
    States Army used many of his products during
    World War I.)

Phillip Downing
  • Phillip Downing invented the letter drop, public
    mailbox in 1891.
  • Downing designed the mailbox to protect the mail
    and to make the mailman's job easier.

    letters out of them and protected letters from
    the rainwater blowing in.

Madame C. J. Walker
  • In 1905, Madame C. J. Walker invented a method to
    soften and smooth black women's hair using
    chemical softeners, hot combs, and curlers, --
    instead of a hot flat-iron.
  • Walker developed The Walker Method, which
    trained her employees to walk door to door
    selling her products.

    millionaire in America.

    for the Love
  • Sharpener.
  • Love's invention was the very simple, portable
    pencil sharpener that many artists use today.

    sharpener and rotated by hand. The shavings stay
    inside the sharpener.

    the fountain pen.

Thomas Stewart
  • Thomas Stewart invented the first mechanically
    clamping mop on June 11, 1893.

    be replaced by unclamping the old mop head and

    mounted on fire wagons in 1878.
  • Winters noticed that firemen had to take ladders
    off of their wagons to climb to windows, rescue
    people, and spray water on fires. He thought they
    should have ladders that they could raise that
    were already mounted to the wagon.
  • Winters' invention was important because a set of
    ladders could reach the high windows on a tall
    building.
