The owner of a drugstore walks

The owner of a drugstore walks in to find a guy leaning heavily against a wall with an odd look on his face.
The owner asks the clerk, "What's with that guy over there by the wall?"
The clerk says, "Well, he came in here at 7 A.M. to get something for his cough. I couldn't find the cough syrup, so I gave him an entire bottle of laxatives."
The owner says, "You idiot! You can't treat a cough with laxatives!"
The clerk says, "Oh yeah? Look at him-he's afraid to cough!"

Typewriter

In 1843, the first U.S. design of a typewriter that successfully typed was issued a patent to Charles Thurber of Norwich, Conn. (No. 3,228) as a “machine for printing by hand by pressing upon keys which contain the type, called ‘Thurber's Patent Printer.’” He was the first to place the paper on a roller and give it longitudinal motion with provision for accurate letter and word spacing. It had a wheel carrying the keys around its circumference. A roller provided inking. However, the machine was slow to use, and only a concept model. Two years later, he patented a design for a writing (not typing) machine, which he called a Chirographer (18 Nov 1845, No. 4,271). On 27 Jun 1857, British Letters Patent were sealed (No. 1805) on Thurber's invention of “An improved caligraph.”«[Image: Thurber's Patent Printer of 1843.]
