The workers in a large office...

The workers in a large office were making secret plans to stage a big office party for the 70-year old cleaning woman who had spent the better part of her life with the company.
Somehow the secret leaked out and the woman got wind of it. Much perturbed, she rushed to the office manager. "Please sir," she cried, "Do not let them do it! Do not let them do it!"
"Oh, come now, Mrs. Smith, you must not be so modest. After all, they simply want to show how much you are appreciated."
"Appreciated, my foot," exclaimed the woman. "I am NOT going to clean up after a mess like that!"

Carpet sweeper patent

In 1876, American inventor Melville (Reuben) Bissell (1843-89) received a U.S. patent for the carpet sweeper (No. 182,346). At his a crockery shop in Grand Rapids, Mich., his wife Anna's health was affected by dust from the packing materials. From a desperate need for self-preservation, he invented the carpet sweeper. They recognized the sweeper's marketing possibilities and began to assemble them in a room over the store. The inner workings and cases were made by women working in their homes. Tufts of hog bristles were bound with string, dipped in hot pitch, inserted in brush rollers and finally trimmed them with scissors. Anna Bissell gathered the parts together in clothes baskets and brought them back to the store for assembling.
