A man walked into a restaurant...

A man walked into a restaurant and saw a sign that read, "We'll give you $300 if we're unable to serve you any entree you order."
He sat down and told the waitress he wanted elephant liver on rye.
The waitress took the order and left.
All of a sudden, the man heard terrible noises coming from the kitchen - the sound of feet stamping, screaming and the banging of pots and pans.
It went on and on.
The noise finally stopped, and the cook appeared from the kitchen.
He slapped down $300 in front of the customer and said, "I can't believe it. We're out of rye."

Shoe manufacturing patent

In 1883, Jan Matzeliger was issued his first U.S. patent for his shoe “Lasting-Machine” (No. 274,207). It provided step-by-step lasting and tacking of a shoe in the same way as the hand method, but much more efficiently. It held the shoe on the last, gripped and pulled the leather down around the heel, then guided and drove the nails in place. The sole could be attached to the upper of the shoe in a minute, significantly increasing the output of finished shoes compared to usual hand work. He later patented further improvements to his machine. The machine was successful, and known as the consolidated hand method lasting machine. He also obtained Canadian Patent No. 24,000 on 7 May 1886 for his “Lasting Machine.”.«
