The Sign

A boss was complaining in a staff meeting the other day that he wasn't getting any respect. Later that morning he went to a local sign shop and bought a small sign that read, "I'm the Boss". He then taped it to his office door.
Later that day when he returned from lunch, he found that someone had taped a note to the sign that said. "Your wife called, she wants her sign back!"

Steam pump

In 1844, Henry Rossiter Worthington (b. 17 Dec 1817, d. 17 Dec 1880) patented the independent single direct-acting steam power pump, an invention which laid the foundation of the entire pump industry. He was a U.S. mechanical engineer, and this invention solved the major steam-engine problem of supplying water to the boiler - even when the engine was shut down - and replaced hand-pumping to keep the boiler filled. He had several inventions leading to the perfection of the direct-acting steam power pump (1845-55), patented the duplex steam pump (1859), and built the first duplex waterworks engine, widely adopted and used for more than 75 years. He established a pump manufacturing plant, New York City, in 1859.
