His ethics and fairness in business paid off as in 1916 impressed with the Upton Companies reputation Sears who ran a mail order only business placed two off Upton's washers in their catalogue. Within one year Sears were selling the washing machines quicker than Upton could make them and they knew that a larger production plant was required. Sears delighted with the products gave Upton a loan to expand his factory in 1921 off $87,000 and two years later agreed to sell exclusively only Upton's washing machines both the electric and rural gasoline versions. With production demands still increasing Upton decided to merge with a company called the Nineteen Hundred Washer Company of Binghamton and the merged company was called the Nineteen Hundred Corporation. This new company continued to grow even through the depression and continued to expand and develop new products until the Second World War started and all appliance production was halted. But Upton was smart and the production lines were carefully dismantled and stored so that after the war restarting production would be a relatively straightforward task.
During the war they were very busy making aircraft parts such as propellers and electric sighting systems and many other components vital to the war effort. Production off washing machines restarted in 1945 with the introduction of a new type of machine the automatic spin washer introduced in 1947 called the Jeep. In 1948 they launched a new range off household appliances which were called the whirlpool range which contained washers, wringers, dryers and irons. Lou Upton retired in 1949 and Elisha Gray II took over as president of the company and in 1950 due to the success of the whirlpool range he changed the company's name to the Whirlpool Corporation and it remains with that name today as one of the biggest household washer, dishwasher and refrigerator appliance manufacturer in the world.
