To Do List

When I returned home from college for a break, I noticed a paper posted on the refrigerator. It listed some goals my dad had set for himself: Help wife more; lose weight; be more productive at work.

I promptly added: “Send Michelle money every month.”

A few days later my brother wrote: “Make payments on car for Jason.”

Then my boyfriend joined in with: “Buy Tom a Jeep.”

Finally my father added a new goal to his amended list: “Wean kids.”

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.
