Baseball boy

A little boy walked up to homeplate in an empty baseball field, with his bat and ball in hand.

As he threw the ball up in the air, he proclaimed, "I am the best ball player ever!" He swung with all his might, but missed.

He did the same thing and missed again.

He picked up the ball, tossed it up one more time, said "I am the best ball player in the world!" Then he swung and missed again.

"Wow!" he said. "What a pitcher!"

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.]
