Birth control pills

An elderly woman went into the doctor's office. When the doctor asked why she was there, she replied, "I'd like to have some birth-control pills."

Taken aback, the doctor thought for a minute and then said, "Excuse me, Mrs. Smith, but you're 72 years old. What possible use could you have for birth control pills?"

The woman responded, "They help me sleep better."

The doctor thought some more and continued, "How in the world do birth control pills help you to sleep?"

The woman said, "Simple. I put them in my granddaughter's orange juice every morning and I sleep better at night."

Rotary washer

In 1858, a U.S. patent was issued for cycling reheated water in a washing machine, to Hamilton E. Smith of Philadelphia, Pennsylvania (No. 21,909). His invention was an improvement for washing machines in which a reciprocating plunger acts on clothes in a tub. His invention placed two horizontal diaphragms in the tub. Both moved vertically with the action of the plunger. The upper one was perforated, and the lower one had a valve. Below the lower diaphragm springs pushed it up as the plunger was lifted. Their motion acted to pump water into the tub from a circuit of pipe that included coils in a heating tank and drained cooler water from the top of the tub. Smith improved his machine and obtained a second patent in 1863.
