His victory had stirred up a lot of controversy as well as the desire for a white man to reclaim the title.
The principle was sound: Women from all classes tried to find ways to get relief from doing laundry. Some hired washerwomen and others used commercial laundries. Eventually mechanical aids lightened the load.
They lugged weighty tubs and baskets full of wet laundry outside, picked up an article, hung it on the line, and returned to take it all down; they ironed by heating several irons on the stove and alternating them as they cooled, never straying far from the hot stove.
This type of washer was first patented in the United States in and survived as late as in the Montgomery Ward catalogue. The first electric clothes washers, in which a motor rotated the tub, were introduced into America about The motor was not protected beneath the machine and water often dripped into it causing short-circuits and jolting shocks.
Byit was possible to buy oscillating, cylinder, domestic washing machines with sheet metal tubs mounted on angle-iron frames with perforated metal or wooden slat cylinders inside.
Manufacturing Challenges From a technological perspective, washing machine manufacturers faced a number of challenges. These included discovering a method of transferring power from the motor to the mechanism, finding a suitable motor with sufficient initial starting torque, and ensuring that the operator did not get an electrical shock during operation.
In the transference of power, some washing machines were chain driven, some belt driven and others used shafts and gears. To overcome the initial resistance in starting a washing machine, a fractional horsepower motor which would not burn out or overheat during the start-up period was used.
The United States Turns Inward: the s and s. After its participation in the conflagration then known as the Great War, the American nation was ready to turn inward and concentrate on domestic affairs (a "return to normalcy," as presidential candidate Warren Harding called it). The s is the decade when America's economy grew 42 percent. Mass production spread new consumer goods into every household. The modern auto and airline industries were born. The U.S. victory in World War I gave the country its first experience of being a . Today the style of a man's suit remains classic and timeless.. Like those of the s. The industrial developments, perfected after World War I, contributed to the death of the quality neighborhood tailor.
To prevent electric shocks, the stator and rotor of the machine were enclosed in a housing equipped with a fan to prevent overheating. Improvements From the customer satisfaction perspective, a machine that would wash without shredding the clothes needed to be developed.
This meant that if the original scrubbing machines were used, the machine had to be operated at different speeds for different textiles.
To overcome the problem, washing machines that sloshed water through the clothing by agitation were developed. Either the tub moved or a baffle placed inside the tub moved. Early washing machines had a heavy, dirty, cast-iron mechanism mounted on the inside of the tub lid.
The introduction of a metal tub and reduction gears to replace this bulky apparatus was a great improvement. Bythe coopered wooden tub was no longer being manufactured.
Beatty Brothers of Fergus, Ontario was the first company to produce an agitator washing machine. The early Beatty machines had ribbed copper tubs which were nickel or nickel-chromium plated.
In the US, the first firm to adopt agitator technology was Maytag. The vertical orientation of these machines became the industry standard replacing the horizontal rotating axis of earlier machines.
Starting in the s, white enamelled sheet metal replaced the copper tub and angle-iron legs.
By the early s, enamelled steel was used and sold as being more sanitary, easier to clean and longer lasting than the other finishes. The sheet-metal skirt was also designed to extend below the level of the motor mount.
In the early s, a number of Canadian machines were offered with built-in gas or electric water heaters. By the s, domestic water heaters were in many homes and the washing machine heater was of little use. The addition of a motor-driven drain pump at this time moved the machine one step closer to complete automaticity.
The next development of the washing machine was the fitting of a clock timing device which allowed the machine to be set to operate for a pre-determined length of wash cycle. Now, the operator no longer needed to constantly monitor its action. By the early s, many American manufacturers were supplying machines with a spin-dry feature to replace the wringer which removed buttons, and caused accidents involving hair and hands.
InGE introduced a washing machine equipped with 5 push buttons to control wash temperature, rinse temperature, agitation speed and spin speed. For bringing housework into the light of historical scholarship, Strasser deserves to have her name become a household word.
