A policeman is on scene at a terrible accident - body parts everywhere. He is making his notes of where the pieces are and comes across a head.
He writes in his notebook: "Head on bullevard", and scratches out his spelling error.
"Head on bouelevard". Nope, doesn't look right - scratch scratch.
"Head on boolevard..." dang it! Scratch scratch.
He looks around and sees that no one is looking at him as he kicks the head. "Head on curb."

Singer's treadle sewing machine

In 1851, Isaac M. Singer of New York City was granted a patent for the first sewing machine with a rocking treadle. Although a sewing machine had already been patented, Singer's sewing machine was revolutionary, having a double treadle. With patent in hand, Isaac set up shop in Boston, Massachusetts and began to manufacture his invention. Even after huge settlements paid to Elias Howe, another sewing machine patent holder, Singer, through business innovations like installment buying, after-sale servicing and trade-in allowances, had the marketplace all sewn up.
