The missus was watching a cooking program the other day.
I said, "What you watching that for? You can't cook."
She said, ........"You watch porn!!."

Rock drill patentIn 1851, James W. Fowle was issued he first U.S. Patent for a direct-action percussion rock-drill (No. 7,972). He had filed a caveat in 1849, about two months after Joseph J. Couch received a patent for the first steam-powered percussion rock-drill. In Couch's design, the drill bar was not fastened to the piston head, but at each stroke was alternately caught, drawn back and thrown against the rock, like a lance. Both employed steam power. At first, Couch and Fowle had collaborated, but Fowle separated to pursue his own design, which is the real precursor of the drills developed in the following decades. To employ the direct action on the drill-bar Fowle had to solve the problem of how to avoid damage to the piston cylinder. He used compressed air to drive his“S” shaped drill.« |
