Washing machine milestones


The first English patent under the category of Washing and Wringing Machines was issued in 1691.A drawing of an early washing machine appeared in the January 1752 issue of "The Gentlemen's Magazine," a British publication. In Germany, Jacob Christian Schäffer's washing machine design was published in 1767. In 1782 Henry Sidgier was issued a British patent for a rotating drum washer.

The first United States Patent titled "Clothes Washing" was granted to Nathaniel Briggs of New Hampshire in 1797. Fire destroyed the patent office and no description of the device exists so it is not known what kind of washing device Briggs invented. A device that combined a washing machine with a wringer mechanism did not appear until 1843 when John E. Turnbull of Saint John, New Brunswick patented a "Clothes Washer With Wringer Rolls."

Electric washing machines were advertised and discussed in newspapers as early as 1904.Louis Goldenberg of New Brunswick, New Jersey invented the electric washing machine around the late 1800s to early 1900s. He worked for the Ford Motor Company at that time, and all inventions that were created while working for Ford under contract, belonged to Ford. The patent would have been listed under Ford and or Louis Goldenberg.[citation needed] Alva J. Fisher has been incorrectly credited with the invention of the electric washer. The US patent office shows at least one patent issued before Mr. Fisher's US patent number 966677 (e.g. Woodrow's US patent number 921195).

US electric washing machine sales reached 913,000 units in 1928. However, high unemployment rates in the Depression years hit sales; by 1932 the number of units shipped was down to about 600,000.

The first laundromat opened in Fort Worth, Texas in 1934[citation needed]. It was run by Andrew Clein. Patrons used coin-in-the-slot facilities to rent washing machines. The term laundromat can be found in newspapers as early as 1884 and they were widespread during the depression. It is almost impossible to determine who had the "first" laundromat. England established public "wash rooms" for laundry along with bath houses throughout the nineteenth century.
