Coffee Maker

The newlywed Blonde went to the store to ask how to operate the new coffeemaker received as a wedding gift. The salesman carefully explained how everything worked; how to plug it in, set the timer, go to bed, and upon rising, the coffee is ready.

A few weeks later the goober was back in the store and the salesman asked her how she liked the coffee maker.

"Wonderful!" she replied, "But... it's just awfully inconvenient to have to go to bed every time I want to make a pot of coffee."

Margaret E. Knight

Died 12 Oct 1914 at age 76 (born 14 Feb 1838).Prolific American inventor of machines and mechanisms for a variety of industrial and everyday purposes. She created, but did not patent, her first invention at age 12, a cutoff safety device that shut down a power loom automatically when a steel-tipped shuttle fell out. Her first patent came in 1870 when she invented a machine to make square-bottomed paper bags, an improvement over V-shaped ones. The 27 patents she eventually held for inventions included a dress and skirt shield (1883), a clasp for robes (1884), a spit (1885)and even a new valve sleeve for an auto engine. She also received six patents over a span of years for machines used in the manufacturing of shoes. She never married, and her creative genius never made her rich. As a self-supporting working-class woman, she had rarely been able to wait for royalties but sold the rights to her inventions outright. Although she was not the first woman to receive a patent, she was one of the most prolific.*
