On July 5, 1910, U.S. Patent No. 963677 issued to Edward H Amet on a Hair Drying Fan.

As the patent explains, the double handles are jointed to allow the user to dry hair on the sides and back of the head.

Amet was born in Philadelphia in 1860. His first patent, age seventeen, was for an improved telephone. In 1884 Amet settled in Waukegan, Illinois, and became a consulting engineer, obtaining patents for coin-operated weighing machines. He designed a clockwork motor for Edison’s phonograph and developed his own phonograph. He also developed a motion picture projector, and other film making equipment, and even produced some films.
Amet eventually settled in California, and by 1911 had filed the first of a series of patents for a synchronised sound camera and projector (US Patent No. 1,065,576). He also worked in 3-D projection, gliders, and a guided torpedo. Edward Amet died 16 August 1948 in Redondo Beach, California.

His hair dryer was probably not his most technical invention, but it is today’s Patent of the Day.
