when was the first front load washer made
Washing machine Bendix Home Appliances, a subsidiary of Avco, an otherwise unrelated company, who licensed the name from Bendix Corporation, introduced the first domestic automatic washing machine in 1937,[23] having applied for a patent in the same year.[24] In appearance and mechanical detail, this first machine was not unlike the front loading automatic washers produced today. Although it included many of the today's basic features, the machine lacked any drum suspension and therefore had to be anchored to the floor to prevent "walking". Because of the components required, the machine was also very expensive. For instance, the Bendix Home Laundry Service Manual (published November 1, 1946) shows that the drum speed change was facilitated by a 2-speed gearbox built to a heavy duty standard (not unlike a car automatic gearbox, albeit at a smaller size). The timer was also probably fairly costly, because miniature electric motors were expensive to produce.
Technological and industrial history of the United States In the mid-1780s, Oliver Evans invented an automated flour mill that included a grain elevator and hopper boy. Evans' design eventually displaced the traditional gristmills. By the turn of the century, Evans also developed one of the first high-pressure steam engines and began establishing a network of machine workshops to manufacture and repair these popular inventions. In 1789, the widow of Nathanael Greene recruited Eli Whitney to develop a machine to separate the seeds of short fibered cotton from the fibers. The resulting cotton gin could be made with basic carpentry skills but reduced the necessary labor by a factor of 50 and generated huge profits for cotton growers in the South.[21] While Whitney did not realize financial success from his invention, he moved on to manufacturing rifles and other armaments under government contract that could be made with "expedition, uniformity, and exactness"â€”the foundational ideas for interchangeable parts.[22] However, Whitney's vision of interchangeable parts would not be achieved for over two decades with firearms and even longer for other devices.
