One day a college professor of Psychology was greeting his new college class. He stood up in front of the class and said, "Would everyone who thinks he or she is stupid please stand up?"
After a minute or so of silence, a young man stood up.
"Well, good morning. So, you actually think you're a moron?" the professor asked.
The kid replied, "No sir, I just didn't want to see you standing there all by yourself."
Caulking gun patentIn 1894, Canadian inventor Theodore Witte of Chilliwhack, British Columbia, was issued a U.S. patent for a "Puttying-Tool" to improve the application "of putty to window sashes and similar things." It incorporated the ratcheted feed now familiar in the caulking gun (No. 512930). The putty is placed in a tube fitted with a nozzle at one end, and a ratcheted lever-operated piston at the other which moves longitudinally through the body in order to squeeze the compound out through the nozzle. The lever is "manipulated so as to force the putty outward as fast as is necessary, and the nozzle is dragged over the surface to be puttied," until the whole mass within the body is ejected from the nozzle. The method has since been adopted to apply a variety of construction materials, including caulking and glue.« |
