Two elderly ladies had been fr...

Two elderly ladies had been friends for many decades. Over the years they had shared all kinds of activities and adventures. Lately, their activities had been limited to meeting a few times a week to play cards.
One day they were playing cards when one looked at the other and said, "Now don't get mad at me... I know we've been friends for a long time... but I just can't think of your name! I've thought and thought, but I can't remember it. Please tell me what your name is."
Her friend glared at her. For at least three minutes she just stared and glared at her. Finally she said, "How soon do you need to know"?

U.S. Patent for Carriage Propulsion

In 1794, U.S. letters patent were granted by George Washington to John J. Staples, Jr., of New York, for what the inventor described as a "Carriage to be Propelled by the Mechanic Powers" (not steam power). However, reading the text of the patent shows that the specifications were vague, and the invention wholly impractical. It proposed five powers be used, including "The first power ... is the weight of the whole carriage ... which is raised up by the oval wheels in turning round, and when descending acts on the shortest lever. 2d Power is the weight of the top frame which supports the carriage body ... which being likewise wound up by the said oval wheels at the same or a different time acts in descending on the two next size levers."
