Launderette reunion

Two elderly ladies meet at the launderette after not seeing one another for some time. After inquiring about each other's health, one asked how the other's husband was doing.

"Oh! Ted died last week. He went out to the garden to dig up a cabbage for dinner, had a heart attack and dropped down dead right there in the middle of the vegetable patch!"

"Oh dear! I'm so very sorry," replied her friend. "What did you do?"

"Opened a can of peas instead."

Fire sprinkler patent

In 1872, the first U.S. patent for an automatic sprinkler system was issued to Phillip W. Pratt, of Abington, Mass., titled “Improvement in Fire-Extinguishers” (No. 131,370). The system consisted of overhead, pivoted water-arms or perforated pipes, which when connected to a supply of water from a supply-pipe would revolve rapidly, throwing water in all directions, wetting ceiling, walls and floor. This operation was controlled by a valve opened by a spring-loaded lever, held closed by a system of cords and fuses. In case of a fire, when the fuses ignited, the cords burned, and the valve opened releasing the scattered stream of water. Pratt was an inventor holding a number of other patents, and is also credited with demonstrating the first electrically powered automobile in the U.S., a tricycle, on 27 Jul 1888.
