1901 Engine-powered vacuum cleaner
British civil engineer H. Cecil Booth patents a vacuum cleaner powered by an engine and mounted on a horse-drawn cart. Teams of operators would reel the hoses into buildings to be cleaned.
1903 Lightweight electric iron introduced
Earl Richardson of Ontario, California (darn, almost Canadian), introduces the lightweight electric iron. After complaints from customers that it overheated in the center, Richardson makes an iron with more heat in the point, useful for pressing around buttonholes and ruffles. Soon his customers are clamoring for the "iron with the hot point"—and in 1905 Richardson’s trademark iron is born.
1905 Electric filaments improved
Engineer Albert Marsh patents the nickel and chromium alloy nichrome, used to make electric filaments that can heat up quickly without burning out. The advent of nichrome paves the way, 4 years later, for the first electric toaster.
1907 First practical domestic vacuum cleaner
James Spangler, a janitor at an Ohio department store who suffers from asthma, invents his "electric suction-sweeper," the first practical domestic vacuum cleaner. It employs an electric fan to generate suction, rotating brushes to loosen dirt, a pillowcase for a filter, and a broomstick for a handle. Unsuccessful with his heavy, clumsy invention, Spangler sells the rights the following year to a relative, William Hoover, whose redesign of the appliance coincides with the development of the small, high-speed universal motor, in which the same current (either AC or DC) passes through the appliance’s rotor and stator. This gives the vacuum cleaner more horsepower, higher airflow and suction, better engine cooling, and more portability than was possible with the larger, heavier induction motor. And the rest, as they say, is history.
1909 First commercially successful electric toaster
Frank Shailor of General Electric files a patent application for the D-12, the first commercially successful electric toaster. The D-12 has a single heating element and no exterior casing. It has no working parts, no controls, and no sensors; a slice of bread must be turned by hand to toast on both sides.
1913 First electric dishwasher on the market
The Walker brothers of Philadelphia produce the first electric dishwasher to go on the market, with full-scale commercialization by Hotpoint and others in 1930.
1913 First refrigerator for home use
Fred W. Wolf of Fort Wayne, Indiana, invents the first refrigerator for home use, a small unit mounted on top of an old-fashioned icebox and requiring external plumbing connections. Only in 1925 would a hermetically sealed standalone home refrigerator of the modern type, based on pre-1900 work by Marcel Audiffren of France and by self-trained machinist Christian Steenstrup of Schenectady, New York, be commercially introduced. This and other early models use toxic gases such as methyl chloride and sulfur dioxide as refrigerants. On units not hermetically sealed, leaks—and resulting explosions and poisonings—are not uncommon, but the gas danger ends in 1929 with the advent of Freon-operated compressor refrigerators for home kitchens.
1919 First automatic pop-up toaster
Charles Strite’s first automatic pop-up toaster uses a clockwork mechanism to time the toasting process, shut off the heating element when the bread is done, and release the slice with a pop-up spring. The invention finally reaches the marketplace in 1926 under the name Toastmaster.
1935 First clothes dryer
To spare his mother having to hang wet laundry outside in the brutal North Dakota winter, J. Ross Moore builds an oil-heated drum in a shed next to his house, thereby creating the first clothes dryer. Moore’s first patented dryers run on either gas or electricity, but he is forced to sell the design to the Hamilton Manufacturing Company the following year because of financial difficulties.
1945 Magnetron discovered to melt candy, pop corn, and cook an egg
Raytheon Corporation engineer Percy L. Spencer’s realization that the vacuum tube, or magnetron, he is testing can melt candy, pop corn, and cook an egg leads to the first microwave oven. Raytheon’s first model, in 1947, stands 5.5 feet tall, weighs more than 750 pounds, and sells for $5,000. It is quickly superseded by the equally gigantic but slightly less expensive Radarange; easily affordable countertop models are not marketed until 1967.
1952 First automatic coffeepot
Russell Hobbs invents the CP1, the first automatic coffeepot as well as the first of what would become a successful line of appliances. The percolator regulates the strength of the coffee according to taste and has a green warning light and bimetallic strip that automatically cuts out when the coffee is perked.
1962 Spray mist added to iron
Sunbeam ushers in a new era in iron technology by adding "spray mist" to the steam and dry functions of its S-5A model. The S-5A is itself an upgrade of the popular S-4 steam or dry iron that debuted in 1954.
1978 First electronic sewing machine
Singer introduces the Athena 2000, the world’s first electronic sewing machine. A wide variety of stitches, from basic straight to complicated decorative, are available at the touch of a button. The "brain" of the system is a chip that measures less than one-quarter of an inch and contains more than 8,000 transistors.
