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.«

A man walked into a doctor's...

A man walked into a doctor's office and the receptionist asked him what he had. He replied, "I got shingles."
She said, "Fill out this form and supply your name, address, medical insurance number. When you're done, please take a seat."
Fifteen minutes later a nurse's aide came out and asked him what he had. He said, "I got shingles."
So she took down his height, weight, and complete medical history, then said, "Change into this gown and wait in the examining room."
A half hour later a nurse came in and asked him what he had. He said, "I got shingles."
So she gave him a blood test, a blood pressure test, an electrocardiogram, and told him to wait for the doctor.
An hour later the doctor came in and asked him what he had. He said, "Shingles."
The doctor gave him a full-cavity examination, and then said, "I just checked you out thoroughly, and I can't find shingles anywhere. " The man replied, "They're outside in the truck. Where do you want them?"
