After a year struggle, women had won the precious right to vote. The generations of suffragists that had fought for so long proudly entered the political world. Carrie Chapman Catt carried the struggle into voting awareness with the founding of the League of Women Voters. Margaret Sanger declared that female independence could be accomplished only with proper birth control methods.
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.
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.
to including the history for each year, events, news, significant technology advances during the time period and Military and Political Leaders. The yo-yo has enjoyed many periods of popularity throughout world history and may be the second oldest toy in the world (after dolls). The automobile was monumental in the evolution of courtship. High speed and moonlight drives inspired a spirit of reckless abandon. In the 19th century, the American world consisted of children and adults. Most Americans tried their best to allow their children to enjoy their youth while they were.
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.Jul 30, Automobile with Combustion Engine It was invented by Henry vetconnexx.com automoblie with the combustion was the most popular invention in the s.

Life moved fast as a new sense of prosperity and freedom emerged at the end of World War I. Products were manufactured in mass-produced packaging. WASHING MACHINE: For centuries, people on sea voyages washed their clothes by placing the dirty laundry in a strong cloth bag, and tossing it overboard, letting the ship drag the bag for hours.
