SMALL EVERYDAY INVENTIONS

Whitcomb L. Judson was an American inventor from Chicago
who was the first to invent, conceive of the idea, and to
construct a workable zipper. The method, still in use today, is based
on interlocking teeth. Initially it was called the “hookless fastener”
and was later redesigned to become more reliable.
The safety match was invented in 1844 in Sweden, by
Gustaf Eric Pasch, improved on by Johan Edvard Lundström, and
prevented unintentional combustion by separating the reactive
ingredients between the match head and the striking surface.
The Band-Aid was invented in 1920 by Earle Dickson, an
employee of Johnson & Johnson, for his wife Josephine Dickson,
who frequently cut and burned herself while cooking. The prototype
product allowed his wife to dress her wounds without assistance.
Velcro is a fabric hook and loop fastener, invented in
1948 by the Swiss electrical engineer George de Mestral.
The first known reference to the name Vaseline was by the inventor
of petroleum jelly, Robert Chesebrough in his U.S. patent for the process
of making petroleum jelly in 1872
The cotton swab or bud was invented in the 1920s by Leo Gerstenzang
after he attached wads of cotton to toothpicks. His product,
which he named "Baby Gays", went on to become the most widely
sold brand name, "Q-tips", with the Q standing for "quality".
Doctors have said for years that usage of the
cotton swab or bud for ear cleaning or scratching is not safe.
THE SAFETY PIN
The safety pin was invented while Walter Hunt was twisting a
piece of wire, trying to think of something that would help him pay
off a fifteen dollar debt. He later sold his patent rights to the safety pin for
four hundred dollars to the man that he owed the money to.
The first modern recorded patent on ball bearings was awarded to
Philip Vaughan, a British inventor and ironmaster who created the first
design for a ball bearing in Carmarthen in 1794. His was the first modern
ball-bearing design, with the ball running along a groove in the axle assembly.
