Raffle prizes!

Bubba & Earl were in the local bar enjoying a beer when the decided to get in on the weekly charity raffle. They bought five tickets each at a dollar a pop.

The following week, when the raffle was drawn, each had won a prize. Earl won 1st prize, a year's supply of gourmet spaghetti sauce and extra-long spaghetti. Bubba won 6th prize, a toilet brush.

About a week or so had passed when the men met back in the neighborhood bar for a couple of beers. Bubba asked Earl how he liked his prize, to which Earl replied, "Great, I love spaghetti! How about you, how's that toilet brush?"

"Not so good," replied Bubba, "I reckon I'm gonna go back to paper."

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.
