Clothes Washer
I.
First thoughts.
Would you name any household duties? What about
washing clothes?
Do you wash your clothes yourself?
Do you wash clothes by hand or with a clothes washer?
II. Study the words. Make sure you know them
stream, soap, laundry, boiler, machine, lye, ashes, to scrub,
to wring, to extract.
III. Read the text and try to point out some features the
washers offer today.
And you wonder why it is called the Stone Age. In the good
old days, clothes were washed in a stream, by bounding the
garments with rocks, stones and heavy sticks. Forget about soap
- water was the sole cleansing agent.
Fire added heat to the laundry mix, when clothes were
washed in tubs with water heated over open fires and soap made
at home from a combination of lye and ashes. Clothes were
scrubbed on a corrugated board, wrung by hand, rinsed, then
wrung again, and draped on lines or bushes to dry. Women's
hands were freed by 1927, when wringer washers became
standard, eliminating the washboard, open tubs and the boiler. A
few "pumps" with the foot started the motor of the machine and
kept it humming.
The first automatic washer - one that washed, rinsed and
extracted water from clothes in one process - debuted at a
county fair in Louisiana, in September of 1937. After World
War II, the demand for washers was enormous. By 1953,
automatic washers were outselling wringer washers ten to one.
Today, washers offer a variety of features including a
selection of cycles for washing different types of garments and
water temperature and level options.
