Preach A Good Sermon

The preacher's 5-year-old daughter noticed that her father always paused and bowed his head for a moment before starting his sermon. One day, she asked him why.
"Well, Honey," he began, proud that his daughter was so observant of his messages, "I'm asking the Lord to help me preach a good sermon."
"How come He doesn't answer it?" she asked.

Lathe

In 1819, a U.S. patent for a profile lathe was issued to Thomas Blanchard of Middlebury, Connecticut. It was capable of manufacturing irregular forms, such as gun stocks. His machine used a friction-wheel to follow the surface of a sample pattern and a cutting wheel on the same shaft which would thus carve the workpiece to the same contour. It could produce the work of 13 operators, and thus provided the finished materials at much less cost. After inventing a tack-making machine at his brother's factory, Blanchard was recruited by the U.S. Armory at Springfield, Mass. to build machines to efficiently produce gun parts. Congress twice extended this patent, first to 1834, then to 1848, giving a total of 42 years in force.*
