ers, built a birthday present for his wife. It was a machine that removed and washed away dirt from clothes. It consisted of a wooden tub in which there was a flat piece of wood containing six small wooden pegs. The inner mechanism looked something like a small milking stool. It was moved back and forth by means of a handle and an arrangement of gears. Dirty clothes were snagged on the wooden pegs and swished about in hot soapy water. Mr. Blackstone began to build and sell his washers for $2.50 each. Five years later he moved his company to Jamestown, New York where it is located today and where it still produces washing machines. Competitors moved in quickly - there have been more than 200 washing machine manufacturers in the U.S. in the past century. Competition has kept keep prices down. Many early washing machines cost less than $10. A wringer, invented in 1861, was added to the washer. Metal tubs replaced wooden types around 1900. Drive belts made possible use of steam or gasoline engines in the early 1900s and electric motor power for the first time in 1906. A rotary handle and a flywheel underneath operated Maytag's first washer, built in 1907. In 1875 there had been more than 2,000 patents issued for various washing devices. Not every idea worked, of course. One company built a machine designed to wash only one item at a time. What may have been the first "laundromat" was opened in 1851 by a gold miner and a carpenter in California. 10 donkeys powered their 12-shirt machine. Earliest washers were hand powered by means of a wheel, pump handle, or similar device. One was driven by twisted ropes that powered the washer by "unwinding" somewhat like the use of a rubber band to power model airplanes. One washer contained rollers that were pushed back and forth by hand to squeeze out dirt. Several featured "stomping" devices and one - called a "Loca-motive" was moved rapidly back and forth on a track washing the clothes by slamming the...
