A Good Day for Ice Fishing

After church, little Johnny and his brother go ice fishing. Little Johnny starts drilling on the ice when a voice from above says, "Young man, there's no fish down there.”
Little Johnny asks his brother, "Who is that?"
His brother replies, "I don't know."
So little Johnny starts to drill again and the voice says again, "For the second time, there's no fish down there."
Little Johnny asks his brother, "Could that be God?"
His brother replies again, "I don't know."
Little Johnny starts drilling again and the voice says once more, "Young man, for the last time, I'm telling you there's no fish down there."
Johnny looks up and asks, "Is that you, God?"
The voice says, "No, I'm the manager and the rink's closed."

Edison patent

In 1893, a patent for a "Roller for Crushing Ore or Other Material" was issued to Thomas A. Edison (U.S. No. 498,385). Edison had in mind crushing iron ore. "It is usual in ore crushing machines employing rollers to mount them in pairs on suitable supporting frames and to provide means for driving each pair, and for feeding material to be crushed separately to each pair of rollers and to provide separate means for pressing the rollers of each pair together. In the machine to be described I employ three or more rollers supported side by side in a frame and moveable towards or away from each other, instead of using them in pairs, and a single weight and lever serves to press all of said rollers together."Image: drawing of the side elevation of the apparatus.
