Steam percussion rock drill

In 1849, Joseph J. Couch received the first U.S. patent for a steam-powered percussion rock drill (No. 6,237) as “improved machinery for drilling rocks”. It was driven by steam power and acted without need of gravity supplying any part of the motion. A sliding drill support frame enabled it to be operated in any desirable position or direction. Power was supplied by the piston of a steam cylinder connected to a suitable steam generator. The machine would be held stationary as the rotating drill was thrown against the rock. The drill rod would disengaged at each stroke, and travel with its own momentum, so that upon striking the rock, the shock was not transmitted back to the rest of the machine, preventing it from damage. After each blow, the tool was seized by means of friction-grips to retract and repeat.«

Old Goat

The young couple invited their aged parson for Sunday dinner.
While they were in the kitchen preparing the meal, the minister asked their son what they were having.
"Goat," the little boy replied.
"Goat?" replied the startled man of the cloth, "Are you sure about that?"
"Yep," said the youngster. "I heard Pa say to Ma, 'Might as well have the old goat for dinner today as any other day.'"
